SQL Server 2005 XQuery and XML-DML - Part 1
You can use it to define a column type for a table, as a parameter or variable in a stored procedure, and anywhere else you would use built-in types such as nvarchar, int, etc. Instead, you can take advantage of two extensions to the XQuery syntax supported by SQL Server 2005 by binding to relational data within your XQuery - as described next
SQL Server - Create an SQL View, Update an SQL View, Drop SQL View
For example you may want to allow employees to see other employees to see the phone number column, but only certain employees to be able to access an employees salary column! Can provide huge time savings in writing queries by already having a group of frequently accessed tables joined together in a view. This is a pretty common thing to do, By having a view that already does this we save having to write that function in every query where this is a requirement
MySQL :: MySQL 5.6 Reference Manual :: 5.1.4 Server System Variables
This is because MySQL relies on the operating system to perform file system caching for data reads, so you must leave some room for the file system cache. When the server begins executing, it inherits a time zone setting from the machine defaults, possibly modified by the environment of the account used for running the server or the startup script
MySQL :: MySQL 5.5 Reference Manual :: 5.1.4 Server System Variables
This is because MySQL relies on the operating system to perform file system caching for data reads, so you must leave some room for the file system cache. There is no gain from setting the buffer larger than required to hold each matching row, and all joins allocate at least the minimum size, so use caution in setting this variable to a large value globally
This feature is very helpful for the DBAs handling lots of partition in a single table and if they want to delete any particular partition(s) data quickly. I am sure it will change the way databases will be designed specially data warehouses because now we do not need to create separate audit tables to record each state manually by using stored procedure or triggers etc while TEMPORAL TABLE is doing it for us behind the scene automatically

While generating the entire data dictionary, you can remove those restrictions and generate it for all the columns (of course you need to add the table name in the select list:-)) In the next and final part of this series, we will build the appendix which will contain additional details like Views, Functions, and other objects. Note that, in the above query we have excluded the dbo schema using the WHERE clause as it is the default schema and we are more interested in the user defined schemas
Another alternative which I prefer is actually in the stored proc if you have a helper function that converts a CSV to a table, then you are able to join on that which is much safer than just sending the input directly to the query.

Generating Insert or Update statements from table data using SQL Server - CodeProject
Anyone using SQL Server on a frequent basis should learn the in's and out's of the metadata built into the system tables - there is virtually nothing that can't be accomplished with a bit of tinkering, some lateral thinking, and clever script.

mysql - How can an SQL query return data from multiple tables - Stack Overflow
There is a limit which depends on your database, but short of recursive functions of some insane and maniacal programmer, most folks will never hit that limit. Some databases will allow a full outer join which will bring back results (whether matched or not) from both tables, but this isn't supported in all databases
You also might have things later in the transaction that are taking longer than you think, and maybe you don't realize that the locks on all of the objects involved in the transaction (not just the statement that is currently running) can be held for the duration of the transaction. In order to improve concurrency, there are several "granularities" of locking that the server might decide to use, in order to allow multiple processes to run: row locks, page locks, and table locks are common (there are more)
In previous versions of SQL Server, we had to write separate statements to INSERT, UPDATE, or DELETE data based on certain conditions, but now, using MERGE statement we can include the logic of such data modifications in one statement that even checks when the data is matched then just update it and when unmatched then insert it. StudentID 2 is deleted as it is more than 250, 25 marks have been added to all records that exists i.e StudentID 1,3 and the records that did not exists i.e
-- Check the content of the table SELECT * FROM Table1 SELECT * FROM Table2 GO As you can see that using JOIN clause in UPDATE statement it makes it very easy to update data in one table from another table. However, the easiest and the most clean way is to use JOIN clause in the UPDATE statement and use multiple tables in the UPDATE statement and do the task
