I have many many column that are char(36) imported from VFP that have been constructed to be cast as UID.
For the most part they convert fine when I
ALTER TABLE tblname
ALTER COLUMN colname Uniqueidentifier
GO
However on the four or five that fail, all I get is
Conversion failed when converting from a character string to uniqueidentifier.
but there are half a million rows, so I don't know where my upsizer is failing to catch a badly formed GUID(36)
Is there a tsql syntax that would be something like (forgive the bad pseudocode but you get the idea)
SELECT success = CAST(cid as Uniqueidentifier) from ACCOUNT_CREDITS where success = false
I need to know which row it chokes on. Could probably write an iteration but seems there must be a set based way to do this.
TIA

Half the harm that is done in this world is due to people who want to feel important. They don't mean to do harm-- but the harm does not interest them. Or they do not see it, or they justify it because they are absorbed in the endless struggle to think well of themselves.
