CASE/Switch Crystal Reports function

[Former Member]

Let's assume column XYZ has both numbers (1), and letters (any alphabet).

I have a case statement on SQL to turn any value that's not 1 into 0, then I am getting a sum of that column.

I am also grouping by Row A, B etc to get aggregated sum of column XYZ for those group.

Now on Crystal Reports function, I need to sum up values under column XYZ for all the groups.

If I try using sum function like below, I get an error stating:

"A number field or currency amount field is required here"

(sum({Command.XYZ}))

So I thought if I can use a case statement to change the non-numbers to 0 prior to sum that will probably resolve it. But I could not get the below case statement to work either (Error: A string is required). 

SELECT {Command.XYZ}

   Case = 1:

      1 

   Default:

      0;

If I try using SWITCH, I receive an error for underlined below "A string is required here"

Switch(

  {Command.XYZ} = 1, 1,

  true, 0

)

Hi Ashish,

You said "I have a case statement on SQL to turn any value that's not 1 into 0, then I am getting a sum of that column." and  "Now on Crystal Reports function, I need to sum up values under column XYZ for all the groups"

So, are you trying to create a similar function in CR or are you trying to just sum up the values that you bring in from the database?

If you're simply trying to 'sum' up the XYZ column that already shows 1 or zero, create a formula in the report with this code:

tonumber({XYZ})

Then, go to Insert > Summart > Choose this formula field > Place this summary on all levels.

Converting using tonumber, then inserting that function as summary worked. Thank you for all of your help!
