Oracle SQL Tutorial 33 - NUMBER Data Type
 
07:18
This video we are going to discuss the NUMBER data type. The Number data type is used to store integers, and real numbers. When you create a column as a NUMBER, you can store pretty huge or pretty small numbers in this column. Now there are two things you need to consider when working with numbers, and that is the precision as well as the how big the number is. For example, we can store the number 9.9. This has two significant digits. We could also store the number 9.9 X 10^4. In this situation, the number is much larger, but the number of significant digits is the same. 9.9 are the significant digits. When we expand this out we just have 99000, and the zeros are just used for size and are not considered "significant" in this situation. In fact, you get a max precision of 38, but a maximum value of 9.99 * 10^125. You can also use this data type to store very small numbers. Check the docs for the specifics on maximums and minimums. You can provide it with two pieces of information: Precision - The total number of digits. Scale - The number of digits to the right of the decimal. You do it in this format: NUMBER (precision, scale). The important thing to remember in this is that when you specify a precision, you will be limiting the max size of the numbers. The secret behind this data type is that it is actually stored in scientific notation. That is we store a number and then we can multiply it by 10 raised to some power. This allows us to store much larger numbers without taking up a ton of space. The oracle docs actually gives a formula that you can use to see how much storage is going to be required for a specific NUMBER data type. How much precision can be used? The acceptable range is 1-38. What about scale? The range is actually -84 to 127. I'll explain the scale in more detail in an upcoming video. That's because there is a lot of confusing things here…What does it mean for the scale to be negative? How can we have a scale that is bigger that the total number of digits available through the precision. That's a topic for another video. It's important to understand that when we increase our scale, we decrease the max size of the number. For example if we have a precision of 5 and a scale of 3, the highest number we can store is 99.999. This is in contrast to a precision of 5 and a scale of 2 which allows for up to 99.999. Either way you get 5 significant digits, but the numbers of digits to the left and right of the decimal change. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Support me! http://www.patreon.com/calebcurry Subscribe to my newsletter: http://bit.ly/JoinCCNewsletter Donate!: http://bit.ly/DonateCTVM2. ~~~~~~~~~~~~~~~Additional Links~~~~~~~~~~~~~~~ More content: http://CalebCurry.com Facebook: http://www.facebook.com/CalebTheVideoMaker Google+: https://plus.google.com/+CalebTheVideoMaker2 Twitter: http://twitter.com/calebCurry Amazing Web Hosting - http://bit.ly/ccbluehost (The best web hosting for a cheap price!)

MySQL 31 - DECIMAL Data Type
 
02:20
The DECIMAL data type is similar to the INT data type in that when you use the number for math, it maintains precision. The difference though is obvious in the name. The DECIMAL data type allows for numbers after a decimal point (and before the decimal point). The DECIMAL data type allows us to store what is known as a fixed-point number. A fixed point number is a number that has a specific number of digits available to store numbers in. That means we can't do things like use a DECIMAL data type to store as many digits of PI as possible, because we can't store unlimited digits. We are limited to a certain number. There are two keywords you need to understand when you are working with the DECIMAL data type, precision and scale. Precision is the number of digits and scale is the number of those digits that will come after the radix. You are going to want to provide these numbers when you declare a column of this data type. For example, DECIMAL(5, 2) has a precision of 5 digits and a scale of 2 digits. That means we can store a maximum of two digits after the decimal and four digits total. This gives us a possible range from -999.99 to 999.99 The highest number of digits is 65, and the highest number of digits after the decimal is 30. This data type is also known as DEC, NUMERIC, and FIXED. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Support me! http://www.patreon.com/calebcurry Subscribe to my newsletter: http://bit.ly/JoinCCNewsletter Donate!: http://bit.ly/DonateCTVM2. ~~~~~~~~~~~~~~~Additional Links~~~~~~~~~~~~~~~ More content: http://CalebCurry.com Facebook: http://www.facebook.com/CalebTheVideoMaker Google+: https://plus.google.com/+CalebTheVideoMaker2 Twitter: http://twitter.com/calebCurry Amazing Web Hosting - http://bit.ly/ccbluehost (The best web hosting for a cheap price!)

MySQL 32 - FLOAT and DOUBLE Data Types
 
06:23
FLOAT and DOUBLE data types are data types that can be used to store numbers that can include decimal numbers. They are specifically used to store estimates. What do I mean? I mean that the precision of a FLOAT or DOUBLE value can be lost when doing math. The data types are only capable of maintaining a certain level of precision. The level of precision is usually adequate for most mathematical operations. If you need to store exact data, you will want to look into using the INT or DECIMAL data type instead. The numbers stored in a FLOAT or DOUBLE column are called floating point numbers, we'll see why in just a moment. Why are they called floating point numbers? let's look at a number. 150. This number could be represented as 150, or it could be represented as 1.5 * 10^2, or 1.5e2. With floating point numbers, scientific notation is used. These numbers are called floating point numbers because the decimal can float to different spots as we change the exponent. This means that the data type needs to store the number, how many decimal the number needs moved, and a sign bit. The benefit of floating point numbers is that they allow us to store pretty huge numbers. The down side is that they are not storing values exactly because they are limited in size. This means that only a certain level of precision is to be expected from a floating point data type. If you remember from the video of DECIMAL, precision is the number of digits in a number. As long as the precision for one of these data types exceeds the need for your specific data, the data type can work fine. For example, if you are storing a number like 15 trillion, you don't have to worry as much with precision as your number does not contain a lot of digits. This number can be represented as 1.5 x 10^13. This is a lot different than trying to store 1.5534534534 x10^13. Now we know both of these data types do not maintain a high number of digits correctly, but what is the difference between FLOAT and DOUBLE. The difference is the amount of storage they take up. Float takes up 4 bytes while DOUBLE takes up 8. The benefit in DOUBLE is that because it has more room to store data, it has a higher level of precision and can store bigger numbers. Now, what level of precision can you expect from either of these? FLOAT around 7 and DOUBLE around 15. Now, these data types are obnoxious because the exact values depend on your operating system and in general these monsters cannot be trusted. Especially when you start doing math with different numbers. In general, it is recommended to use the DOUBLE data type to have a higher level of precision and calculations in MySQL are done with DOUBLE. Always remember… prepare for trouble, make it double. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Support me! http://www.patreon.com/calebcurry Subscribe to my newsletter: http://bit.ly/JoinCCNewsletter Donate!: http://bit.ly/DonateCTVM2. ~~~~~~~~~~~~~~~Additional Links~~~~~~~~~~~~~~~ More content: http://CalebCurry.com Facebook: http://www.facebook.com/CalebTheVideoMaker Google+: https://plus.google.com/+CalebTheVideoMaker2 Twitter: http://twitter.com/calebCurry Amazing Web Hosting - http://bit.ly/ccbluehost (The best web hosting for a cheap price!)

Oracle MONTHS_BETWEEN Function
 
02:17
https://www.databasestar.com/oracle-months_between/ The Oracle MONTHS_BETWEEN function allows you to find the number of months between two dates. You can enter two dates and the function returns the difference. This function is often used as part of other calculations. Sometimes you’ll want to know the difference between two dates to perform other functions. The syntax of the MONTHS_BETWEEN function is: MONTHS_BETWEEN(date1, date2) What do these two parameters mean? The function performs date1 minus date2. So, if date1 is larger, the result is positive. If date2 is larger, then the result is negative. What data type is returned? It depends on the values you provide. If the dates are both on the same day of the month (e.g. both on the 10th of the month), then the result is an integer or whole number. If not, then the result will be a decimal value. For more information on the MONTHS_BETWEEN function, including the code used in this video and examples, read the related article here: https://www.databasestar.com/oracle-months_between/

MySQL 33 - Datetime, Date, Time Data Types
 
06:40
Next up on our MySQL to-do list is to learn about storing dates and times. There are various data types in MySQL for storing dates and times. It seems MySQL and databases likes to break everything up into multiple data types to make things more organized at the consequence of being confusing and annoying. This video is going to be talking about the DATETIME, DATE, and TIME data types. These are all used to store, you guessed it, dates and times. The one you choose depends on your needs. If you just need dates, choose DATE. If you just need times, choose TIME, if you need both stored together, choose DATETIME. Now you set a column one of these data types whenever you want every row for this field to have some sort of date, time or both…but how exactly is the data formatted? This requires us to understand some convention. For example, in the USA at least, if you have something like 4:30AM, by convention you know the hour is 4 and the minutes are 30. But this is just an agreed upon convention. MySQL has its own convention…For example 2017-02-02. The first thing is the year, the second is the month, and the third is the day. That is for the DATE. The convention for time is 22:54:30. The first is the hour (military time), the second is the minute, and the third is the seconds. Lastly, there can actually be fractions of seconds…up to microseconds! .123456. To use fractional seconds though you must specify to MySQL the precision of the TIME or DATETIME when you create it, for example DATETIME(6) would allow microsecond precision. How do you actually give a date to MySQL? By that I mean let's say you have a table with a column of DATETIME(6), and you want to give a value for that column, how do you format it? It's quoted. For example: '2017-02-02 22:54:30.333333' MySQL interprets this as a DATETIME. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Support me! http://www.patreon.com/calebcurry Subscribe to my newsletter: http://bit.ly/JoinCCNewsletter Donate!: http://bit.ly/DonateCTVM2. ~~~~~~~~~~~~~~~Additional Links~~~~~~~~~~~~~~~ More content: http://CalebCurry.com Facebook: http://www.facebook.com/CalebTheVideoMaker Google+: https://plus.google.com/+CalebTheVideoMaker2 Twitter: http://twitter.com/calebCurry Amazing Web Hosting - http://bit.ly/ccbluehost (The best web hosting for a cheap price!)

Check if Value is Numeric by using ISNUMERIC & TRY_Convert Function in SQL Server - TSQL Tutorial
 
13:38
How to Determine if value is Numeric by using ISNumeric and Try_Convert Function in SQL Server - TSQL Tutorial ISNUMERIC( ) function is provided to us in SQL Server to check if the expression is valid numeric type or not. As per Microsoft it should work with Integers and Decimal data types and if data is valid integer or decimal, ISNumeric() should return us 1 else 0. But ISNUMERIC() does not work as expected with some of values specially when we have "-" or "d" in value and have two numbers after "d" such as 123d22, it still return us 1. Also if we have data in money format $XXXXX e.g $2000, It returns us 1. In SQL Server 2012. Microsoft introduced new function call Try_Convert( ). You can use try_convert function to convert to required data type and if it is not able to convert then it will return Null as output. As you will see below, I did some experiment and found out that Try_Convert will produce 0 for "-" when we try to convert to Int, That should not be happening as "-" is symbol not Integer. But when I try to convert "-" to decimal, Try_Convert produced Null output. Take a look in below results and keep in mind the outputs when you have to evaluate expression to Numeric or find out if expression is Numeric or Not.

Oracle SQL Tutorial 25 - ASCII and Unicode
 
03:33
In the previous video we talked about some of the most popular data types. We are going to discuss them in more detail. The data type we are going to start with is CHAR and NCHAR. I told you of both of these but I never explained the difference. That's because there is some other stuff I need to explain before I can explain the difference. This has to deal with what is known as character sets. When you have a string, there are only so many characters you are allowed to store in that string. The characters you are allowed to store is determined by what is known as the character set. A common character set is ASCII. This character set allows you to store English characters, numbers, and some symbols. ASCII started with 127 characters, and then they came out with the ASCII extended, which allows for up to 255 characters. Even with 255 characters though, we are limited in what we can store using one character set. If the computer only allows ASCII, we are going to be limited when working with different languages. Of course it works for some situations, but globalization of software has been a big thing with the development of the interwebs …and the movement towards a new world order (Revelation 13:7). That means that ASCII is no longer the best character set. It has largely been replaced with a character set known as Unicode. Oracle has a few Unicode character sets that we can use when we work with string data. When you start studying character sets, I can promise that you will run across the word encoding. Encoding refers to the way that the allowed characters can be stored on the computer. A computer doesn't just store a letter, everything has to be stored in binary. Unicode is the character set, but it has numerous different encodings. Essentially, the computer can store the same characters in multiple different ways, depending on which encoding is used. The most popular encodings for Unicode are UTF-8 and UTF-16. UTF stands for Unicode Transformation Format. In the next video we will be discussing these in detail and express their differences. Once we got that down, we'll be able to loop back around to data types. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Support me! http://www.patreon.com/calebcurry Subscribe to my newsletter: http://bit.ly/JoinCCNewsletter Donate!: http://bit.ly/DonateCTVM2. ~~~~~~~~~~~~~~~Additional Links~~~~~~~~~~~~~~~ More content: http://CalebCurry.com Facebook: http://www.facebook.com/CalebTheVideoMaker Google+: https://plus.google.com/+CalebTheVideoMaker2 Twitter: http://twitter.com/calebCurry Amazing Web Hosting - http://bit.ly/ccbluehost (The best web hosting for a cheap price!)

Converting Julian days into date and time in excel
 
01:46
How to convert Julian days into dates in excel In this video I show how to change the cell formatting in excel and use custom formatting to show Julian days as date and time. Julian days are simply a continuous count of days and fractions instead of dates. They were originally called Julian days because they came from the Julian calendar and started on noon Universal Time on January 1, 4713 BC. However the name is now used for other continuous counts of days.

MySQL 25 - CHAR Data Type
 
04:47
The first category of data types that we are going to cover in this MySQL series are the string data types, or character data types. There are two that I am going to talk about in this video, CHAR and VARCHAR. We'll start with CHAR. CHAR is a string data type where you specify how many characters are allowed in parenthesis after you declare the column as this type. For example, we can say CHAR(50) to allow up to 50 characters for each value in that column. The thing to know about CHAR though is that it is a fixed-length string. That means every single value inside of that column is actually going to be whatever you declare the length as. So if you say CHAR(50), every string is going to be 50 characters long. If, for example, you have a row that only uses 40 characters, MySQL will pad the right side of the string with spaces until it fills 50 characters. Now, the highest value you can put in here is 255. The 255 refers to characters. This means that you can have strings with up to 255 characters. How does the computer know how to store these characters? That has to deal with the character set and the encoding of the characters. By default, MySQL is going to use UTF-8. We are not going to discuss UTF-8 in detail for a while but essentially UTF-8 says that each character can take up to 3 bytes of storage. 255 comes from the max number you can count to using binary. So if we are keeping track of how many values are in this column in an 8 bit number, 255 is the highest. If you don't know what I'm talking about it, we'll worry about it later. You can actually make the column CHAR(0). In this situation, the only thing you could put in as a value for this column is an empty string (''). When retrieving variable length CHAR data from a database it may not look like the database pads the value. That's because MySQL actually strips spaces from the value when presented. If you want to keep all of the spaces that have been added when you retrieve the value, you can do that. Look up PAD_CHAR_TO_FULL_LENGTH online. In the next video we are going to discuss VARCHAR. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Support me! http://www.patreon.com/calebcurry Subscribe to my newsletter: http://bit.ly/JoinCCNewsletter Donate!: http://bit.ly/DonateCTVM2. ~~~~~~~~~~~~~~~Additional Links~~~~~~~~~~~~~~~ More content: http://CalebCurry.com Facebook: http://www.facebook.com/CalebTheVideoMaker Google+: https://plus.google.com/+CalebTheVideoMaker2 Twitter: http://twitter.com/calebCurry Amazing Web Hosting - http://bit.ly/ccbluehost (The best web hosting for a cheap price!)

round an average to 2 decimal places in postgreSQL
 
03:33
If you have an average value , how to round it up to 2 / more decimal places . 1. You don't always have to typecast it to numeric either . You can just say round(avg(salary),2) as well . While converting to a numeric datatype does make sense , it is not always required . 2. small change : at 0:44 , I refer to using job title and salary as the main columns , that is inaccurate . We will be using department and salary as the main columns . Hope this helps . Thanks !

Date type conversion from any date format to any date format in DataStage
 
04:30
Use the type conversion functions to change the type of an argument. StringToDate Returns a date from the given string in the given format. You do not have to specify a format string if your string contains a date in the default format yyyy-mm-dd. Input: string (string) [,format (string)] Output: result (date) Examples: If the column mylink.mystring contains the string ″1958--08--18″, then the following function returns the date 1958--08--18. StringToDate(mylink.mystring) If the column mylink.mystring contains the string ″18:08:1958″, then the following function returns the date 1958--08--18. StringToDate(mylink.mystring,"%dd:%mm:%yyyy")
