How to drop a table if it exists

0 votes

The table name is Scores.

Is it correct to do the following?

IF EXISTS(SELECT *
          FROM   dbo.Scores)
  DROP TABLE dbo.Scores

Hello @kartik,

No. That will drop the table only if it contains any rows (and will raise an error if the table does not exist).

Instead, for a permanent table you can use

IF OBJECT_ID('dbo.Scores', 'U') IS NOT NULL 
  DROP TABLE dbo.Scores; 

Or, for a temporary table you can use

IF OBJECT_ID('tempdb.dbo.#T', 'U') IS NOT NULL
  DROP TABLE #T; 

Hope it works!!
Thank you!
