Use CASE in WHERE clause - Data Parameters Sql Server -

-

i'm trying verify example, if date null pick date field. below query:

select     *     orderpublish op     inner join advertising ad on         ad.idorderpublish = op.idorderpublish     inner join client cli on         cli.idclient = op.idclient     left join advertisinginserted aii on         ad.idadvertisinginserted = aii.idadvertisinginserted     left join typeproduct tp on         aii.idtypeproduct = tp.idtypeproduct     inner join publication pub on         pub.idadvertisinginserted = aii.idadvertisinginserted     tp.idtypeproduct in (5,7)     , case when pub.dtini null                     op.dtinc >= isnull('08/18/2013', op.dtinc)         else             pub.dtini >= isnull('08/18/2013', pub.dtini)         end     , case pub.dtfinal when null                     op.dtinc <= isnull('08/23/2013', op.dtinc)         else             pub.dtfinal <= isnull('08/23/2013', pub.dtfinal)         end

you can coalesce() in case, if want use case in where criteria can so. move matching criteria outside case statement, need case statement return values compared, not comparison itself. requires doubling each case statement:

select     *     orderpublish op     inner join advertising ad on         ad.idorderpublish = op.idorderpublish     inner join client cli on         cli.idclient = op.idclient     left join advertisinginserted aii on         ad.idadvertisinginserted = aii.idadvertisinginserted     left join typeproduct tp on         aii.idtypeproduct = tp.idtypeproduct     inner join publication pub on         pub.idadvertisinginserted = aii.idadvertisinginserted     tp.idtypeproduct in (5,7)     , case when pub.dtini null                     op.dtinc         else             pub.dtini          end     >=  case when pub.dtini null                     isnull('08/18/2013', op.dtinc)         else             isnull('08/18/2013', pub.dtini)         end      , case pub.dtfinal when null                     op.dtinc          else             pub.dtfinal          end     <= case pub.dtfinal when null                     isnull('08/23/2013', op.dtinc)         else             isnull('08/23/2013', pub.dtfinal)         end

that's how can use case statement in where criteria, use and () , or () criteria along coalesce() without case

also, isnull() statements backwards, '08/18/2013' never null, field won't evaluated, mean: isnull(op.dtinc,'08/23/2013')
