Performance Tuning SQL Server Cursors - SQL Server Performance
The greater the number of rows being modified, the greater the locks, and the higher the likelihood of lock contention on the server, hurting performance. LOCAL cursors are more secure as they cannot be referenced outside the procedure or trigger unless they are passed back to the calling procedure or trigger, or by using an output parameter
Most business applications will need some sort of PIVOT queries and I am sure many of you must have come across pivoting requirements several times in the past. CREATE TABLE invoice ( InvoiceNumber VARCHAR(20), invoiceDate DATETIME, InvoiceAmount MONEY ) The above SQL statement creates a table for the purpose of this example
Angie Reply shaunmacrae Says: November 17, 2011 at 8:07 pm You can also incorporate parameters into your query when using the query designer (rather than manually writing sql code) in the applied filters section. In the Default Values we can pick or set a value to be the default, and the Advanced lets us determine how often we need to refresh the source data for our parameter
Another restriction decided as well in the time frame of SQL Server 7.0 development was meant to avoid small tables frequently getting updated in statistics by requiring at least 500 rows to be in the static table (6 rows in temp tables). As a result some customers reported update statistics taking place extremely rarely and with that outdated statistics sometimes resulting in query plans which were not optimal

OR GIVE ME A EXAMPLE TO KNOW HOW TO DOTHANK YOU VERY MUCH!! Dave Oct 27, 2009 at 9:50 PM 1 Comments Hi J.D,If you can join ECRPYHS and ECRHDHS, it should be easy to join PAYINFO as well. It doesn't happen all that often (most of my SQL is fairly simple), but every now and then someone shows me something that just rocks my world, whether it be the power of Indexing or just something as simple as using UNION ALL instead of UNION
UPDATE from SELECT using SQL Server - Stack Overflow
If the source table is on the many side of a one to many join then it is undeterministic which of the possible matching joined records will be used in the Update (An issue that MERGE avoids by raising an error if there is an attempt to update the same row more than once)
How to update two tables in one statement in SQL Server 2005? - Stack Overflow
The columns cannot be derived in any other way, such as through the following: An aggregate function: AVG, COUNT, SUM, MIN, MAX, GROUPING, STDEV, STDEVP, VAR, and VARP. Columns that are formed by using the set operators UNION, UNION ALL, CROSSJOIN, EXCEPT, and INTERSECT amount to a computation and are also not updatable
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
