If you query the sysobjects table, with a query like

SELECT * FROM sysobjects WHERE xtype = 'U' AND name = 'yourTableName'

xtype = 'U' is a user table

you can then wrap this is an IF EXISTS statement

IF EXISTS (SELECT * FROM sysobjects ...)
BEGIN
    ' do your stuff here if it exists
END

    +1 It is important to note that Microsoft has been moving functionality like this to Dynamic Management Views (DMVs) since SQL Server 2005. This will technically work, but Microsoft now recommends using the sys.tables DMV for this. IF EXISTS(SELECT * FROM sys.tables WHERE type = 'U' AND name = 'yourTableName'). Functionally, your statement and my statement do the exact same thing. Just wanted to mention DMVs. To learn more about DMVs, check out the documentation http://msdn.microsoft.com/en-US/library/ms188754%28v=SQL.105%29.aspx – Matt M Jan 27 '11 at 13:12
  • That's a good call Matt. Old habits die hard :-) Yours is the better way. – Miles D Jan 27 '11 at 15:02

    I'm not sure if it makes much difference but I'd favour IF EXISTS (SELECT 1 FROM sys.tables...) – David Hayes Aug 03 '11 at 20:06
  • @DavidHayes Yes, I guess this solution is faster because it does not query to find column names. – Xriuk Feb 04 '18 at 18:19

Here is one more way of finding it

IF OBJECT_ID('tablename') IS NULL
PRINT 'Table Does not Exist'

IF EXISTS (SELECT * FROM INFORMATION_SCHEMA.TABLES 
           WHERE TABLE_NAME = 'your table name here')
BEGIN
  PRINT 'Table Exists'
END
