It has todo with performance since every SQL which varies only in its parameters will result in a new query parsing and compile unless simple parameterization kicks in consuming CPU unnecessarily and filling your plan cache with garbage.

Temp tables created in EXEC can not use temp table caching mechanism. Ahmad Abuhasna Ahmad Abuhasna 2, 3 3 gold badges 19 19 silver badges 35 35 bronze badges. Darren Darren 1 1 silver badge 5 5 bronze badges. You really should mention that in more significant detail than just the next steps.

That could easily be missed. I actually wrote a function to go through a string column list like your example, and apply quotes [] to the names to block sql injection. Just different ways of executing a dynamic statement. I must develop a stored procedure in a dynamic way. But the operand of the "where" clause must be a parameter. I think that Dynamic SQL is the solution, but we consider this one not enough "elegant" and the Sql injection issue too These variables can be used anywhere, in strings, as server, table, or database name, or even parts of names.

The variable definition is active for the entire script, even across GO. You can write multi-server scripts, like a database copy. I want to store the result of a dynamic query into a variable, assuming the query returns only 1 value. Is there anyway to see the actual SQL state being created with the parameters actually substituted.

It is a little confusing that I used the same name twice. Hopefully that helps answer your question. Francisco - try something like this. Not sure if this is exactly what you need to do or not. I have a Dynamic select, I want to choose dynamically the columns of table 2 who have names as a month but I dont want to use the complete name when I call them with SSRS, my question is how to save the results of this Dynamic Select in Table 2?

I can not do it can someone help me. Everywhere it tell me to store the result into a temp table and then query the temp table to store the value into a variable. Can anybody please help me if there is any easier way to directly put the result into a variable, just like how mysql lets you with keyword into variable in its dynamic query. I can execute my dynamic SQL statement, but when I use it in a stored procedure, I can't get at the data. As a simple example, when I run the following in a query window, it returns a set of data:.

But when I put the same statement in a stored procedure and try to return the set of data, calling the stored procedure just gives me:. I usually write queries whose ouptput itself is a query. Is there a way to execute the ouptut of the query without copy pasting and runing it? Later i realized that some of keywords within the stored proc are in upper case and some in lower case,now to give it a standard look i want to change all the lowercase keywords into uppercase.

For that i need a query or stored proc. I was trying but couldn't find out how to get all the keywords used within a stored proc. Would be very thankfull if you could help me Roberto - this isn't exactly true. Always remember that anything called by EXEC statement is executed in a separated session.

So you can't use:. I have 4 textbox firstname, middlename, lastname and city. User will enter data in any of the four textbox during runtime. So the problem is, on submit I have to build an sql query during run time for my asp. I wisht to fetch out the total record count from the Table.

The following syntax gives me error. Can some one help me on the same. I need to develop a "generic" statement that works in various databases. Each DB has the same set of table names, e. There is a fourth DB where all stored procedures are housed, e. My stored procedure has to allow user of the branch office to grab the data pertaining to the branch location.

The real difference is whether a parameterized plan will be cached. Thanks for the post, explains the difference well. Those pesky lines in the query plan can be difficult to see at times — caught me a couple of times. But I hate using those.

And, they work just like stored procedures in that their plan is determined by the first execution. As a result, you can end up with a bad plan getting into cache and then being reused for subsequent executions. Oh, and we take cash, check, and all major credit cards ;-.
