检查数据库中是否存在某个表，不存在则生成该表
方法一：
IF NOT EXISTS (select * from dbo.sysobjects where xtype='U' and Name = 'T_Users')
BEGIN
CREATE TABLE [dbo].[T_Users](userName varchar(20),userPass varchar(20));
END
方法二： create procedure sel_tab @table_name varchar(20) AS declare @flag int set @flag=0; set @flag = (select flag from (select count(*) as flag from dbo.sysobjects where xtype='U' and Name = 'T_Users') as sel_count); if @flag = 0 create table T_Users(userName varchar(20),userPass varchar(20)); GO EXEC sel_tab "T_Users"
