it seems like you would need transaction control. also, in you sql
statement, there should be a clause that allows you to set a wait time for
data control language (dcl) when encountered a locking issue. often, it is
undesirable to have locking issues within an app. probably should start
looking at your codes, or looking into database performance tuning. also,
your issue could specifically be a C issue. so it could be an area that
you can look into as well...good luck! tim
