If this is a one to many relationship you may need to get more complex to truly get the answer you want. A denormalized table like this can be much more difficult to query when you need data from several of these numbered fields.My database (dbo_finance) column - test The other database is assestsc and I am going to pull the data from column issuename1, however I only want to pull the issuename1 when the field [Min Sec Class] is = 9.This is what I wrote also, these different tables are in seperate SQL servers dbo_finance table is in dev01.finance(server, database) and assets C table is in dev02.dw(server, database) didnt know to do that so i left it out for [email protected] toby, primary key in Assets C is a security ID field that doesnt match anything in dbo_finance, completely unrelated field, what will match up is my dbo_finance key is cusip9, that should match up perfectly with assets C.cusip (assets C.cusip will always be unique)MERGE INTO dbo_finance USING (SELECT Issue Name1, cusip FROM Assets C WHERE Min Sec Class = 9) AS source ON dbo_= source.After each exercise, we provide the solution so you can check your answer.
