Hello, I've got a databasese with 55 mil records. I've got about 30 update statements which have to run in a particular sequence. When I run a single update statement in the query analyser, it take for example 30 minutes to run. But when I run all the statements in a row, some of them will run for more that a day!! Is there anyone who can point me in the right direction? TIa, Gerben.
