The last step in the above code creates following table EMP:
The addition of blank (' ') between strings has returned a desired output. But the addition of comma(,) between strings has returned so many undesired commas. Main question/concern is how to remove the UNNECESSARY commas (especially at the end)in the data/records returned under the COMMA column? I can reduce the length of variable to 11 char to get rid of a comma (in the first row: sea, contrct,) but that won't solve the issues with the other rows that have shorter strings. There will still be unnecessary commas.
Any help would be greatly appreciated.
