Question

I have a procedure called Insert and the code looks like:

Create procedure Gen_insert
As
BEGIN


create table #temp
 ( insert_stmt varchar(max) ) 
 insert into #temp  
EXEC Generate_Insert @Table = 'Admin'

 insert into #temp  
EXEC Generate_Insert @Table = 'Impas'

 insert into #temp 
 EXEC Generate_Insert @Table = 'Asui'

 insert into #temp 
 EXEC Generate_Insert @Table = 'Alstd'  

select * from #temp 

End

When I execute it I am getting following error:

Msg 8164, Level 16, State 1, Procedure Gen_Insert, Line 73
An INSERT EXEC statement cannot be nested.

Can anyone help me.

Answer 1

An INSERT EXEC statement cannot be nested. The error message is quite clear. You are nesting INSERT … EXEC. statements. Either the procedures you call (Generate_Insert) use again INSERT … EXEC or the caller of insert procedure uses it in an INSERT … EXEC. Only you can find which is the case. As a rule of thumb, INSERT … EXEC should be avoided, because of this and other problems.
