使用：
Usp_OutputData 'contact',0
结果：
insert contact(FirstName,LastName,EmailAddress,testdate) values( N'AAAAA' , N'BBBBB' , N'CCCCC' , NULL )
insert contact(FirstName,LastName,EmailAddress,testdate) values( N'xxx' , N'BBBBB' , N'CCaaaa' , NULL )
insert contact(FirstName,LastName,EmailAddress,testdate) values( N'AAAAA' , N'BBBBB' , N'CCCCC' , NULL )
insert contact(FirstName,LastName,EmailAddress,testdate) values( N'AAAAA' , N'cc' , N'CCCCC' , NULL )
insert contact(FirstName,LastName,EmailAddress,testdate) values( N'AAAAAxxx' , N'BBBBB' , N'CCCCC' , NULL )
insert contact(FirstName,LastName,EmailAddress,testdate) values( N'ccccc' , N'BBBBB' , N'CCCCC' , NULL )
