its properly work 3 times but at 4 or 5th time when i use bulk insert command all data are successfully inserted into table but it lost the sequence.
after 1136th row 201545th row added and break all the sequence
Please Give me Proper Solution for that.
What do you mean by "lost the sequence"? How are you determining what the sequence is? Tables have no inherent sequence and insertion order is not something you can determine just by looking at the data in a table. The way to order a table is using an ORDER BY clause in your SELECT statement.
In your case it looks like you have an IDENTITY column and you are using the KEEPIDENTITY option to insert those values directly from the file. Are you saying the IDENTITY column values don't match the data in the file?
