Exclude rows that do not have data type uniqueidentifier value in them

[aalbetski]

I am trying to query a table and return only the rows where the value in Column1 can be cast as a uniqueidentifier. I run into problems when the cast fails (Syntax error converting from a character string to uniqueidentifier.) and am stumped as to how to do this. Any ideas?

select * from table where Column1 = cast(Column1 as uniqueidentifier) -- this, of course fails when non-guid data is found

Column1-------C762C6D6-6167-4B3C-B493-CB1294FF0FFD8E9D557F-B899-4B66-91DB-81DAC3D1D4AE00-11-22-9918-49-e4-33-a1-20-1b-91-a4-40-77-81-6a-7e-d5-df29-70-c8-c2-1e-b9-d9-ee-cb-26-55-04-8d-c9-19-e5

got it

select * from table where column1 like '________-____-____-____-____________'

not my first choice, but it works
