Cry How to...
Create a table unless it already exists
To create a table in SQL Server, unless it has already been created:
if not exists (select * from sysobjects
where name='<table_name>' and xtype='U')
create table <table_name>' ...
where <table_name> is the name of the table. The 'xtype' field holds the type of object, 'U' denoting a user defined table.
if not exists (select * from sysobjects where name='cars' and xtype='U')
create table cars (
Name varchar(64) not null
These notes have been tested against SQL Server 7 and SQL Server 2000, SQL Server 2005 and SQL Server 2008.
