Ive searched StackOverFlow , and didnt find any.
Is there any way for me to know if a Table Variable already exists ?
something like :
IF OBJECT_ID('tempdb..#tbl') IS NOT NULL
DROP TABLE #tbl
but for table Var…
Table variables, because they are variables, are distinct from either temporary or non-temporary tables in that they are not created – they are declared. They are much closer in that respect to ‘normal’ variables rather than to tables.
So, there’s as much sense in talking about a table variable’s existence as in talking about the existence of any variable: if you have declared the thing in your source code, it exists starting from that point until the end of its scope, which, in SQL Server, is known to be either the batch or the stored procedure/function it is declared in. And if you haven’t declared the variable and are trying to reference it in your code, your code will just not compile, rendering any existence check pointless, if ever possible.
Perhaps, if you feel the need to drop and re-(create/declare) a table variable in your script, then you should probably consider using a temporary table instead.
