This is my problem

Table A has columns ID1,ID2 and NAME
Table B has columns ID1 and CATEGORY
Table C has columns ID1, ID2

B.CATEGORY can have the value X,Y and Z
A.ID2 has not had any values assigned

Step A: Get C.ID1, C.ID2 where C.ID1=B.ID1 and B.CATEGORY = 'X'
Step B: Update A.ID2 with C.ID2 where C.ID1 = A.ID1 for the records selected in step A

I am using DB2
