Question

im trying the dynamic cursor concept in my stored procedure in oracle i used the stmt as below:

OPEN d for
            'select datetime,'|| v_paramname ||',tt from datasource where '|| v_vrformula ||' and  feederid=cast('||v_meterid||',varchar2(6)) and datetime>=:v_timeperiod' using v_timeperiod;
    LOOP
    FETCH d INTO V_dateval,V_value,V_dataid;
    EXIT WHEN d%NOTFOUND;
    INSERT INTO pseb.validationfailureaudit (MeterID,RuleID,DataType,Value,Dataid, TimePeriod,EditedValue,EditedTimePeriod,paramname) VALUES  (V_meterid,V_ruleid,V_datatype,V_value ,V_dataid,V_dateval,null, null,V_paramname);
    V_length:=V_length+1;
    END LOOP;
CLOSE d;

I m getting missing keyword error in open statement.

Please help me to solve it.

Answer 1

You seem to be missing as AS clause in the CAST:

... and feederid=cast('||v_meterid||' AS varchar2(6)) ...
