Crystal report; Combining rows of data into a single value

Question

I have a data in rows like this for id 1

id1 a1

id1 b2

id1 c3

id1 d4

id1 e5

I like to combine it as \"a1b2c3d4e5\" into a sin

Answer 1

It will depend on the data type for the columns a1-e5 and what you're trying to do with the single value.

If you're just trying to display the value, you can create a formula that uses Crystal's ToText() function to first convert them to strings and then concatenate them together using '+'.

ToText({id1.a1}) + ToText({id1.b2}) + ToText({id1.c3}) + ToText({id1.d4}) + ToText({id1.e5})

You could accomplish the same thing on the DBMS side, also.

If you can provide more info, we might be able to come up with a better solution.
