Hi Nuwandi, The parameter type should be set as ARRAY instead of SCALAR if you want to input an array. For example,
<param name="employeeNumbers" ordinal="2" paramType="ARRAY" sqlType="INTEGER" type="IN"/> However the NPE should be fixed. Can you create an issue for that. In the request you can send the payload as in [1] [1] https://docs.wso2.com/display/DSS351/Data+Types+of+Mappings#DataTypesofMappings-Arraydatatype On Sat, Oct 20, 2018 at 1:58 AM Nuwandi Wickramasinghe <nuwan...@wso2.com> wrote: > Hi, > > I'm trying (With EI 6.4.0) to create an operation for a db query where the > input param *SQLType* is defined as an *ARRAY*.
