Question

I know, I know with what I wrote in the question I shouldn’t be surprised. But my situation is slowly working on an inherited POS system and my predecessor apparently wasn’t aware of JOINs so when I looked into one of the internal pages that loads for 60 seconds I see that it’s a fairly quick, rewrite these 8 queries as one query with JOINs situation. Problem is that besides not knowing about JOINs he also seems to have had a fetish for multiple databases and surprise, surprise they use different collations. Fact of the matter is we use all “normal” latin characters that English speaking people would consider the entire alphabet and this whole thing will be out of use in a few months so a bandaid is all I need.

Long story short is I need some kind of method to cast to a single collation so I can compare two fields from two databases.

Exact error is:

Cannot resolve the collation conflict
between
“SQL_Latin1_General_CP850_CI_AI” and
“SQL_Latin1_General_CP1_CI_AS” in the
equal to operation.

Answer 1

You can use the collate clause in a query (I can’t find my example right now, so my syntax is probably wrong – I hope it points you in the right direction)

select sone_field collate SQL_Latin1_General_CP850_CI_AI
  from table_1
    inner join table_2
      on (table_1.field collate SQL_Latin1_General_CP850_CI_AI = table_2.field)
  where whatever
