I have an SQL Server Database with 100's of tables with as many rows in each and I'm turning on CDC for some reporting. Since data was created/inserted BEFORE turning on CDC, the CDC tables are current empty and I would like to get the data into the CDC tables to start reporting.
Is there a way to 'refresh' or seed the existing data into the CDC tables?
I've tried a simple update with existing data, however this doesn't actually cause a CDC entry. Presumably it isn't writing to the transaction log and triggering an write.
UPDATE table1 SET column1 = column1;
In my case, most of my tables currently have an
UPDATEDON column which I could just update to a now timestamp, which will cause an update and subsequent entries in the CDC tables, but I'd prefer to retain the existing update time.
UPDATE table1 set UPDATEDON = getDateUtc();
Alternatively I could go through and move all the data into temporary tables, delete the data and re-insert it to cause updates, but surely there is a better way? How have others tackled this?
