What is limit in MySQL Limit Data Selections From a MySQL Database. MySQL provides a LIMIT clause that is used to specify the number of records to return. The LIMIT clause makes it easy to code multi page results or pagination with SQL and is very useful for large tables. The SELECT TOP clause is useful on large tables with thousands of records. Returning a large number of records can impact on performance.

11 MySQL Tutorial for Beginners: The LIMIT Clause
 
06:36
The LIMIT clause limits the number of rows in the result set. In its simplest form, you code the LIMIT clause with a single numeric argument. If you code a single argument, it specifies the maximum row count, beginning with the first row. If you code two arguments in a LIMIT clause, the first one represents the starting point for the result set, also called the "offset". This "offset" starts to count from a value of zero. This means that zero refers to the first row in the result set, one to the second, two to the third and so on. SELECT, FROM, WHERE, ORDER BY, and LIMIT are the five main clauses of the SELECT statement but only the SELECT clause is required. When you code the SELECT clause, you should include only the columns you really need (for example, you shouldn't code an asterisk to retrieve all the columns unless you need all the columns). That's because the amount of data that's retrieved can affect system performance. That goes for retrieving rows too. The fewer rows you retrieve, the more efficient the statement will be. Because of that, you typically include a WHERE clause on your SELECT statements with a search condition that filters the rows in the base table so only the rows you need are retrieved EXERCISES for your SELF-TRAINING: http://golearnfast.com/Quizzes.php?_SelectSmallerGroup_288=0&Lessons_ID=288 SCRIPT FOR THE EXAMPLES: http://www.golearnfast.com/files/lessons_material/lesson_277_1440544998.sql SUBSCRIBE! https://www.youtube.com/channel/UCMEaGDoHU7c9tWyafZ9vC6Q?sub_confirmation=1 FACEBOOK https://www.facebook.com/golearnfast GOOGLE+ https://plus.google.com/u/0/b/101326338689489366802/

Use NOCOPY to Improve Performance

Top Nine Coding Guidelines for Oracle PL/SQL
 
08:00
My take, as of November 2015, of some of the most helpful guidelines to follow when writing PL/SQL code: 1. MAXSQL - maximize use of SQL first and foremost 2. SPOD - single point of definition 3. TRACE - production-available application-level tracing 4. LOG - consistent, encapsulated error logging 5. BULK - avoid row by row 6. OBVIOUS - make your code tell its own story, comment when it can't 7. NESTPROG - use nested subprograms 8. DECLARE - use declarative features of language 9. WARN - use compile-time warnings Accompanying blog post: http://stevenfeuersteinonplsql.blogspot.com/2015/10/your-ideas-for-more-important-plsql.html ======================================== Practically Perfect PL/SQL with Steven Feuerstein Copyright © 2015 Oracle and/or its affiliates.

Oracle DB Vs MySQL for Enterprise DataBase Deployments
 
08:54
Oracle DB is big, and expensive, but it brings a lot to the "table" when compared with MySQL. MySQL has limited ability to audit. MySQL's security is unsophisticated. There are no groups or roles, no ability to deny a privilege (you can only grant privileges). A user who logs in with the same username and password from different network addresses may be treated as a completely separate user. There is no built-in encryption comparable to Oracle. MySQL's Authentication is built-in. There is no LDAP, Active Directory, or other external authentication capability. MySQL has no MPP (massively parallel processing ) support. Unlike Oracle MySQL has no fractional-second storage type for times, dates, or intervals. There is no RAC (Real Application Cluster) support in My SQL, and no failover or server promotion either. These are strong features in Oracle MySQL's number of joins per query is limited to 61. Oracle's limit is much larger. MySQL Replication is asynchronous and has many limitations and edge cases. For example, it is single-threaded, so a powerful slave can find it hard to replicate fast enough to keep up with a less powerful master.

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!)
