将 XML 变量从存储过程传递到 SQL 服务器中的另一个存储过程

Question

I have 2 stored proc.

The first one receive as input parameter some variables and one of them is XML.

Inside this proc i call another proc but dynamically like that. This proc handle the XML to insert it in the DB.

SET @SQL = 'EXEC [' + @ServerIp + '].[List_' + CAST(@AccountId AS VARCHAR) + '].[dbo].[psu_proc_name] @ParameterId = ' + CAST(@ParameterId AS VARCHAR) + ',@MappingFields = ' + @MappingFields

@MappingFields is the name of the XML variable in the first proc and also in the second proc (called dynamically)

I manage the treatment of the XML in the second proc (dynamic) but i don't know how to pass the parameter as XML to the second proc.

Thanks

Answer 1

The best way to do this is to use the sp_executesql stored procedure instead of using the simle exec command. See the not duplicate, but very clear examples in the question EXEC sp_executesql with multiple parameters for easy to understand details.

Answer 2

i've tried something like that:

SET @SQL = N'EXEC [' + @ServerIp + '].[List_' + CAST(@AccountId AS VARCHAR) + '].[dbo].[psu_opensystem_field_mapping_add]'
EXEC sp_executeSQL @SQL, N'@ParameterId INT, @MappingFields XML' , @ParameterId, @MappingFields

But it says that

Procedure or function 'psu_opensystem_field_mapping_add' expects parameter '@ParameterId', which was not supplied
