NO. We can use mapping parameters or variables in any transformation of the same maping or mapplet in which U have created maping parameters or variables.

I have a table having column col1, col2. If for a col1 there is some data in col2.

EX: Col1=0012 and Col2 = 12,13,14

then i need these three values 12, 13,14 separately not as a single string as it is in table. Or you can say in need to separate these three values after it is returned by query.There may be only one value or more than 3 as well.
