Peut-être qu'un peu plus de SQL dynamique fera l'affaire (avec un parseur)
Declare @String varchar(max) = '1,25,659'
Declare @SQL varchar(max) = ''
Select @SQL = @SQL + concat('Exec [dbo].[sp1] ',Key_Value,';',char(13))
From (Select * from [dbo].[udf-Str-Parse-8K](@String,',')) A
Select @SQL
--Exec(@SQL)
Retours
Exec [dbo].[sp1] 1;
Exec [dbo].[sp1] 25;
Exec [dbo].[sp1] 659;
L'UDF si besoin (super rapide !)
