sql - Insert Or Update After a Merge -


i have following merge operation on ms sql server.

declare @data xml declare @id int declare @version rowversion set @data = ? set @id = ? <# if ( tw.local.enableoptimisticlocking == true ) { #> set @version = cast(? rowversion) <# } #> merge [<#=tw.local.dbschema#>].[<#=tw.local.tablename#>] target using (select @id id, @version version ) source on target.id = source.id when matched <# if ( tw.local.enableoptimisticlocking == true ) { #> , target.version = source.version <# } #>     update set data = @data when not matched     insert (data) values (@data) output $action _action<# if ( tw.local.enableoptimisticlocking == true ) { #>, cast( inserted.version bigint) [version]<# } #>, inserted.id;

i wish have insert / update statement db , table update columns based on results of above merge.

i not sure if can have other insert/update inside merge or need use output data want insert/update merge?

i tried following not work....

declare @data xml declare @id int declare @version rowversion set @data = ? set @id = ? <# if ( tw.local.enableoptimisticlocking == true ) { #> set @version = cast(? rowversion) <# } #> merge [<#=tw.local.dbschema#>].[<#=tw.local.tablename#>] target using (select @id id, @version version ) source on target.id = source.id when matched <# if ( tw.local.enableoptimisticlocking == true ) { #> , target.version = source.version <# } #>     update set data = @data when not matched     insert (data) values (@data) output $action _action<# if ( tw.local.enableoptimisticlocking == true ) { #>, cast( inserted.version bigint) [version]<# } #>, inserted.id, inserted.version, inserted.data;  if exists (select inserted.* inserted left join deleted on inserted.id = deleted.id deleted.id null)     begin         insert [emeaworkflowbpm].[cmf].[businesscontextreporting] (id, version, data, updatedon, toprocess)         select i.id, i.version, i.data, getdate(), 1         inserted         left join [emeaworkflowbpm].[cmf].[businesscontextreporting] bcr         on i.id = bcr.id , i.version = bcr.version         bcr.id null;     end else if exists (select inserted.* inserted inner join deleted on inserted.id = deleted.id)     begin         update [emeaworkflowbpm].[cmf].[businesscontextreporting]         set version = i.version, data = i.data, updatedon = getdate(), toprocess = 1             inserted             left join [emeaworkflowbpm].[cmf].[businesscontextreporting] bcr             on i.id = bcr.id;     end

many in advance time , help.

you have combine output clause , make updates , inserts new statement following merge.

take @ accepted answer in question:

using merge..output mapping between source.id , target.id
