Is there an IIF Function in SQL Server?
Posts: 8 Thanks: 0 Thanked 0 Times in 0 Posts Is there an IIF Function in SQL Server? Hi All, This is slightly off topic, but I am developing an ASP application using SQL Server. If you have posted the question and it is not answered after a reasonable period of time, then add a comment to your question asking why hasn't anybody helped
I tried the SQL Server Replace function , but it replaces only one character or a sequence of character and not each occurrence of each of the specified characters given in the second argument i.e 'et'

Since I was not able to determine which parts of the conditions in the IF statement where false the ELSE portion printed the message "Not in Northwind database or Table Customer does not exist". If you have complicated logic that needs to be performed prior to determining what T-SQL statements to execute you can either use multiple conditions on a single IF statement, or nest your IF statements
Paging in SQL Server 2005
The record count is used to prevent returning empty results when possible, and to support paging interfaces that calculate the number of pages available (such as GridView). If we were calling this stored procedure to populate a GridView, we would return @recct as a ReturnValue parameter instead of using a result set, but we will use a result set for demonstration purposes
Inside trigger you can add a check like this, if (condition to check if remote server database is online) begin perform what ever your action you want to perform. In addition to this, the CATCH block captures and provides error information that shows you the ID, message text, state, severity and transaction state of an error
if given condition is satisfied by compiler then cursor rollback deleted records to table and condition is not satisfied then cursor commit that record. you can always conditionalize on the @@ROWCOUNT variable if you need to have different trigger functionality defendant on whether only one row or multiple rows where effected
There are situations in which a server database is the proper solution; there are other situations in which a simple desktop database is theproper solution. I would kindly suggest that you test your two example queries, because I would hazard a guess that you'll find that the performance is the exact opposite of what you expect
Finally, you might also have issues with NULL values and performance problems in general as you nest these IN clauses one inside another, especially if you use the even more dreaded "Nested WHERE-NOT IN" anti-pattern. Can you provide a specific example where a nested in performs better? I'm definitely curious, it would be very interesting to see something that performs better with all the INs, and I'm willing to revise my statements if we can find that scenario.In terms of extensibility, if technique A always performs equally or better than technique B, they have approximately the same complexity, and technique A also has the benefit of better extensibility, I will personally stick with technique A

Because, in reality, it is not feasible to always know which procedure will be the outermost procedure in the chain, a certain amount of flexibility is necessary. Attempting to execute a second rollback will generate an error with the message 'The ROLLBACK TRANSACTION request has no corresponding BEGIN TRANSACTION.'

Overview of Error Handling in SQL Server 2005 - CodeProject
There are some scenarios like, we are expecting some rows should come when we will execute the store procedure, but unfortunately SP returns none of them. As I have already said, @@Error returns the error number for the last Transact-SQL statement executed, so if we execute any @@Error statement, we will get output 0

IF ELSE with WHERE, AND, OR - Microsoft SQL Server
Can I use CASE statements in the WHERE section? Or is that strickly for SELECT statements? You cannot use CASE statements, because there are none in T-SQL. For this reason, one sometimes has to duplicate code in a way that conflicts with the best practices you've learnt when working with traditional languages
Nested if statements in SQL Server stored procedure SELECT statement - Stack Overflow
I am trying to build a stored procedure (MS SQL Server 2005) that takes a number of passed in values and in effect dynamically builds up the SQL as you would with inline SQL. I've hugely simplified the code in the above example for clarity, since it's the general concept of a nested IF statement with SELECT and ORDER BY that I'm inquiring about
SQL Server Forums - Nested If Then Else vs. Multiple If's
This seems rather inefficent to me and as a result my question is that do you think that grouping these statements under blanket if clauses will actually speed up the stored procedure? I really want to do this but it would be hard to justify the work and risk if it really won't help at all.All you optimizers out there, would love some input
