Subj:   SQL Case statement help needed.
 
From:   mark barlow

I am relatively new SQl coder and am struggling to get to grips with the syntax of case statements.

In the code below the place the code falls over on is or (a.code = c.code), I would be grateful if someonce could point out where I am going wrong please?

     insert into table_1
     select
     b.id,
     brand,
     case when (substr(offer,1,5) between 'G100' and 'G816' )
      or (offer not like 'G%' and substr (band,1,1) = 'T')
      or (a.code = c.code) then 1
             else 0
     end,
     case when (substr(offer,1,5) not between 'G100' and 'G816')
      and substr (band,1,1) ne 'T'
      and (a.code ne c.code) then 1
             else 0
     end
     from table_4 a,
     table_5 b,
     table_6 c
     where a.id = b.id
     and date >= date '2004-01-31'
     group by 1,2,3,4
     ;
