"GO SET QUOTED_IDENTIFIER OFF GO SET ANSI_NULLS ON" Dear friends,could you please let me know,what the above syntax signifies. Thanks, Amara
Hi, ------------------------------------------------------------------------------------------------------ When SET QUOTED_IDENTIFIER is ON (default), all strings delimited by double quotation marks are interpreted as object identifiers. Therefore, quoted identifiers do not have to follow the Transact-SQL rules for identifiers. They can be reserved keywords and can include characters not generally allowed in Transact-SQL identifiers. Double quotation marks cannot be used to delimit literal string expressions; single quotation marks must be used to enclose literal strings. If a single quotation mark (') is part of the literal string, it can be represented by two single quotation marks ("). SET QUOTED_IDENTIFIER must be ON when reserved keywords are used for object names in the database. When SET QUOTED_IDENTIFIER is OFF, literal strings in expressions can be delimited by single or double quotation marks. If a literal string is delimited by double quotation marks, the string can contain embedded single quotation marks, such as apostrophes. ------------------------------------------------------------------------------------------------------ i would suggest to refer BOL for more.

thanks hemanth. I got another doubt: Say I want to create ab table in a Database.I first want to check whether we have any table of that name or not.If that table is already there,query shld print out a message that table already exists.if the table is not there it should create one CREATE TABLE [dbo].[temporary] ( [DriveLetter] [varchar] (1) COLLATE SQL_Latin1_General_CP1_CI_AS NULL , [Reason] [varchar] (255) COLLATE SQL_Latin1_General_CP1_CI_AS NULL , [DenyDate] [datetime] NULL ) ON [PRIMARY] GO what should be the syntax to check if this table exists or not:
you may use object_id function to check the existance of the object from master..sysobjects table. Regards Hemantgiri S.

Note that the current settings are saved with the stored procedure definition and will be used everytime you execute the procedure. Roji. P. Thomas Microsoft SQL Server MVP http://toponewithties.blogspot.com
if object_id('temporary') is not null print 'table exists' else CREATE TABLE [dbo].[temporary] ( [DriveLetter] [varchar] (1) COLLATE SQL_Latin1_General_CP1_CI_AS NULL , [Reason] [varchar] (255) COLLATE SQL_Latin1_General_CP1_CI_AS NULL , [DenyDate] [datetime] NULL ) ON [PRIMARY] GO quote:Originally posted by amara thanks hemanth.

quote:if object_id('temporary') is not null print 'table exists'That systax is common to check for all objects. To check for table, then use sysobjects with xtype='u' or make use of ObjectProperty Madhivanan Failing to plan is Planning to fail
