Example: use temporary tables in dynamic SQL

Source: Internet
Author: User

-- Define counters and dynamic SQL strings
Declare @ itcount Int = 0;
Declare @ strsql nvarchar (max) = NULL;

-- Create a temporary table
If object_id ('tempdb .. # mytable') is not null
Drop table # mytable

Create Table # mytable (strname nvarchar (50), strpass nvarchar (50 ));

-- Assign values to temporary tables cyclically
While @ itcount <100
Set @ itcount = @ itcount + 1;
Insert # mytable values ('str: '+ Cast (@ itcount as nvarchar), @ itcount );

-- Dynamically Execute SQL strings
Set @ strsql = 'select * from # mytable'
Execute (@ strsql );

Additional: currently, the test result is that table variables cannot be queried in dynamic SQL. Therefore, the temporary table is used as the processing container for temporary data.
