动态SQL中的动态表

Question

i have a declared a table :

DECLARE @V_TABLE (ROW_ID INT IDENTITY(1,1), CLIENTKEY, UNIQUEIDENTIFIER)

i have tried to use this table in a piece of dynamic sql

SET @SQL = ' INSERT INTO #CLIENTTABLE ( CLIENTKEY )
              (SELECT CLIENTKEY FROM '+ @V_TABLE  +')'

the code keeps asking me to declare @v_table how can i use this table in the dynamic sql

Answer 1

In your query @V_TABLE is a table variable and not a string variable containing the name of the table. Hence, if the query is prepared like so, it should work.

SET @SQL = ' INSERT INTO #CLIENTTABLE ( CLIENTKEY )
              (SELECT CLIENTKEY FROM @V_TABLE')'
