    Question Unanswered: Bulk Update Advice

    Hello,

    We are building a data warehouse that pulls it's data from a DB2 database into Sql Server. The table that we are pulling from in DB2 has a 1 character field to determine if we have already loaded that record into the warehouse. The problem that we are experiencing is that updating the flag in DB2 is taking way too long because we have to iterate over the records. Does anyone have some advice on a better way to handle this in DB2?

    Thank you for help in advance!

    Make sure you don't have an index on the indicator column. It probably would not be used for retrievals anyway.
