We call many stored procs using myBatis which have IN / OUT parameters which we know how to handle
But I dont know how to handle when the procedure actually returns a value instead of declaring it as a OUT param
For example using a SQL editor (TOAD for SQL Server) I can run a proc and get a return value as so:
DECLARE @return_value int;
EXEC @return_value = someProcedure
@param1 = 'abc',
@param2 = 12345
SELECT @return_value as N'@Return Value';
GO
However I have only ever gotten results as either result sets and dont know how to handle this scenario. I thought something like this might work:
<select id="callSomeProcedure" resultType="java.lang.Integer" statementType="CALLABLE">
{ call someProcedure (
#{param1},
#{param2}
) }
</select>
But it returns NULL
Any ideas?
OK got it
<select id="callSomeProcedure" statementType="CALLABLE">
{ #{returnVal} = call someProcedure (
#{param1},
#{param2}
) }
</select>
