Question

Here\'s a very simple question. I have an SP that inserts a row into a table and at the end there\'s the statement RETURN @@IDENTITY. What I can\'t seem to find is a way to

Answer 1

One point to mention. You should really use SCOPE_IDENTITY to return the identity value after INSERT. There is potential for @@IDENTITY to return the wrong value. Especially if TRIGGERS are in use, writing value to other tables after INSERT.

See the Books Online page for more detail.

Answer 2

BTW, in most circumstances, you should use SCOPE_IDENTITY() rather than @@IDENTITY. Ref.

Answer 3

Dim c as new sqlcommand("...")

Dim d As New SqlParameter()
d.Direction = ParameterDirection.ReturnValue
c.parameters.add(d)

c.executeNonQuery

(@@IDENTITY) = d.value

It is more or less like this...either this or just return the value from a stored procedure as an output parameter.

Answer 4

Sounds to me like you want to execute with a scalar value

SqlCommand.ExecuteScalar()

as others have mentioned I think using SCOPE_IDENTITY() is more secure than the @@IDENTITY variable

Answer 5

Someone says use

IDENT_CURRENT('TableName')
