    dim cryrpt new reportdocument      cryrpt.load(application.startuppath & "\reports\report1.rpt")      dim crparameterfielddefinitions parameterfielddefinitions     dim crparameterfielddefinition parameterfielddefinition     dim crparametervalues new parametervalues     dim crparameterdiscretevalue new parameterdiscretevalue      crparameterdiscretevalue.value = textbox1.text     crparameterfielddefinitions = _     cryrpt.datadefinition.parameterfields     crparameterfielddefinition = _     crparameterfielddefinitions.item("controlid")     crparametervalues = crparameterfielddefinition.currentvalues      crparametervalues.clear()     crparametervalues.add(crparameterdiscretevalue)     crparameterfielddefinition.applycurrentvalues(crparametervalues)      rptreport         .crreport1.reportsource = cryrpt         .crreport1.refresh()     end      rptreport.show()

here new stored procedure on mysql database

create definer=`root`@`localhost` procedure `sreadings`(in `controlid` int) begin      select         a.controlid,         a.data1,         a.data2,         a.date1,         a.date2      shifts     a.controlid = @controlid; end

but loading report throw me error:

failed retrieve data database. details: [database vendor code: 1318].

removing in controlid int stored procedure where a.day_id = @controlid removes error need filter data controlid provided user via vb interface.
