Dear all, I have an urgent (aren't they all) question about ESQL/C. How do you change the isolation level to dirty read in an ESQL/C program ? I have an insert trigger which calls a stored procedure that calls an ESQL/C program:- The ESQL/C program tries to select a blob from the row which is being inserted so that it can take the blob and split it up to lines of text in a separate table. The problem is that the ESQL/C program gets Error -245 Could not position within file via an index ISAM Error: -144 key value locked I though setting isolation level to dirty read could bypass the lock ?? How do I do that ??. Thanks in advance, David.
