Hello Everyone,

I have one table which have results stored in 5 fields. In the parameter form, I am asking the user to choose the fields to be shown. User can select all the fields or any one of them.
In the report the results should come as per his selection.

I have tried using lexical parameter but it has the restriction.

code for the test table:
CREATE TABLE TESTING1
(
  ID  NUMBER,
  T1  NUMBER,
  T2  NUMBER,
  T3  NUMBER,
  T4  NUMBER,
  T5  NUMBER
)
Insert into TESTING1
   (ID, T1, T2, T3, T4, 
    T5)
 Values
   (1, 1, 2, 3, 4, 
    5);
Insert into TESTING1
   (ID, T1, T2, T3, T4, 
    T5)
 Values
   (2, 1, 2, 3, 4, 
    5);
Insert into TESTING1
   (ID, T1, T2, T3, T4, 
    T5)
 Values
   (3, 1, 2, 3, 4, 
    5);
Insert into TESTING1
   (ID, T1, T2, T3, T4, 
    T5)
 Values
   (4, 1, 2, 3, 4, 
    5);


Please help.

Use format triggers to hide the fields the users haven't selected.

Yes I have tried format trigger also but suppose if the user only selects the last field (i.e. test 5 in our table) then the report will show space for 1 to 4 field and then last field.... it will not look good.

True, reports isn't really designed to cater for this requirement.
You could try combining all the columns into a single result column, using || and nullif and then probably the pad functions to get uniform spacing.

I have tried that also but all the fields come nearby and I was unable to put space between them.

I have found one solution for this. I have selected all the fields in the main query and used same amount of formula columns in it. Now, according to the selection I am filling the data into the Formula columns.

Thanks cookiemonster for your consent.
