Guest column: Delaney has a different take on Boonie Williams case Prosecutors and police from the era recall a different case than the one that the media described. Gentlemen, I am having a hard time to get column/field values from the last union select query. The new dataset can exist within the same project, but must not have the same name as the. ) i need a query to merge these so all characters from all 4 different fields are in one column, an not merged into one field. The UNION operator removes by default duplicate rows from the result set. Right, I forgot to say you need to null or otherwise default the columns that don't line up as cyberkiwi mentioned. The Select All and Deselect All buttons can be used to make the selection faster.
