Have you ever worked up a example to display dynaimc source to destination data column mapppings using the same technique, and also the matching of data items from source column to destination columns, basically a frgament of code that replicates the SSIS data mapper, removing the need to map source to destination in SSIS...?

I've been coming to these forums long enough to know that Joe Celko was going to respond to this one. I recall Joe discussing the TOP clause in another forum long ago. Correct me if I'm wrong Joe, but TOP isn't to be trusted to pull the "first rows in a table" because tables don't store rows in any particular order. Is that what you were going for in your re-education reprimand? I've always felt it was a little misleading...it should have been called LIMIT or something like that because that's all it's really doing...limiting the result set.

IMHO.

What I would like to see is a source to destination dynamic data mapper, which is all referenced by using the dynaim columns as in the exmaple you have used, only extended to to also reference a second table, which agin the ordinal positions are sorted to relfect the data mapping, and then having further SQL conditions tagged on to allow a filter to be put in place.

I want two tables, ordinal position to relfect the data mapping sequence, the source and destination columns and condition blocks may exist in either table, a dynamic process to put it all together, just the SQL part, don't want to execute it.....
