Build-view tools / Autogen processes should never build views using "SELECT * FROM..."

Any automated processes such as View Builder in Collect, or any Autogen processes that build views typically in dswXXX databases shouldn't use the coding to build views of "SELECT * FROM xxx".

Views should be built by reading the metadata information to find every column, and build out the explicit SELECT statement with each columnname.

    John has SOLD me on this - the case of the shifting of fields and "non-breakage" of view, but integrity issues that could be hidden and cause VERY BAD THINGS is something I have had happen. I still think this is an edge case as any table schema change should only be done via an autogen activity/recycle, but this is good hygiene. VOTED UP!

    This should extend to our methodology where our consultants should NEVER do SELECT * in a view they are creating (e.g. off a target). ALWAYS select all the fields.

    You'll have to sell me on this one for a vote. :-) What is the downside of current implementation?
