Hi Gareth,
As a general point, NEVER put a commit or rollback in a directly executed database procedure. Down that path lies madness. I suspect the ODBC is simply bitching about this.
You should also check the value of iierrornumber on entry to the procedure. Ensure you have all the locks you will need before the procedure really gets going.

Subject: [Info-Ingres] Stored procedures and ODBC
I have this stored procedure...
create procedure testit as
begin
update test set col1 = date('now')
rollback;
end
When I run this from isql it works fine, when I run it from ODBC it throws an erro, and in the errlog.log it says:
E_QE0258_ILLEGAL_XACT_STMT A commit/abort/rollback was attempted in a context where transaction statements are not allowed.
Heres the straight foreward calling code from visual basic .net
Dim cnn As New Odbc.OdbcConnection("dsn=imadb")
Dim com As New Odbc.OdbcCommand
com.Connection = cnn
com.CommandType = CommandType.StoredProcedure
com.CommandText = "Execute Procedure testit"
cnn.Open()
com.ExecuteNonQuery()
cnn.Close()
com.Dispose()
cnn.Dispose()
So I'm not wrapping the call in any transaction that I'm aware of, is this something to do with auto commit?
Cheers
Gareth
