Question

I am trying to create a stored procedure that selects from a database name that would be parameterized. However, I am having a lot of trouble doing so. I am trying to perform something as simple as the following:

DECLARE @tableName VARCHAR
SET @tableName = 'MY_TABLE_NAME'

SELECT
  *
FROM
  @tableName

This produces the error: Incorrect syntax near '@tableName'.

Could someone please tell me how I could select from a parameterized table name?

Answer 1

Execute dynamic SQL in this case.

DECLARE @tableName VARCHAR 
SET @tableName = 'MY_TABLE_NAME'
exec('
SELECT
  *
FROM ' + @tableName )
