ref_no datatype is number and we are creating text_parameter. Is this creating problem?Why do you have the leading Zero's if REF_NO is a NUMBER? Oracle will automatically strip the leading Zero's unless you specify REF_NO as a VARCHAR2. Your code sample used 000001 so this implied your REF_NO was a VARCHAR2. Is the Data Type of :PARAMETER.A_REF_NO a NUMBER or a CHAR? If it is a CHAR, you will need to cast the value to a NUMBER using the TO_NUMBER() function. You can't rely on Oracle to implicitly convert the CHAR to NUMBER - in fact - Oracle strongly recommends you always cast data type conversion rather than relay on implicit conversions.
And wht do you mean by where clause in forms? are you talking about data block------properties-----------Query data source type------ From clause query------------ (WHERE ref_no=:PARAMETER.A_REF_NO)>
Is your Datablock based on a From Clause Query? If yes, you can't using the BLOCK WHERE property to filter your block records. You will have to alter the From Clause Query each time. Let me know if you are using a From Clause and I'll show you how to make this work.
