0	Hi Maximum column can be 1024. Do you want to confirm it ? DECLARE @nTable INT, @Sql NVARCHAR(MAX) SELECT @nTable =1, @Sql ='CREATE TABLE TB_TABLE1(' WHILE(@nTable<=1025) BEGIN SELECT @Sql = @Sql + 'Col' + CAST(@nTable AS VARCHAR(4)) + ' INT,' SELECT @nTable = @nTable +1 END SELECT @Sql = LEFT(@Sql,LEN(@Sql)-1) + ')' EXEC(@Sql) You'll get an error Msg 1702, Level 16, State 1, Line 1 CREATE TABLE failed because column 'Col1025' in table 'TB_TABLE1' exceeds the maximum of 1024 columns. So, The maximum column can be 1024 Cheers www.sqlserverbuddy.blogspot.com Cheers www.SQLServerbuddy.blogspot.com iLink Multitech Solutions Johnseelan, if this helps please login to Mark As Answer. \| Alert Moderator

Hi

Maximum column can be 1024.

Do you want to confirm it ?

DECLARE @nTable	INT,

	@Sql		NVARCHAR(MAX)

			

SELECT @nTable =1, @Sql ='CREATE TABLE TB_TABLE1('



WHILE(@nTable<=1025)

BEGIN

	SELECT @Sql = @Sql + 'Col' + CAST(@nTable AS VARCHAR(4)) + ' INT,'

	SELECT @nTable  = @nTable +1

END



SELECT @Sql = LEFT(@Sql,LEN(@Sql)-1) + ')'



EXEC(@Sql)

You'll get an error

Msg 1702, Level 16, State 1, Line 1

CREATE TABLE failed because column 'Col1025' in table 'TB_TABLE1' exceeds the maximum of 1024 columns.

So, The maximum column can be 1024

0	Even though the max number is 1024.. Try to normalize your tables for better performance and easy readable. Thanks and Regards Madhu Johnseelan, if this helps please login to Mark As Answer. \| Alert Moderator
