Hi,

I am new to DB2 and would appreciate any help with the SQL query.

I have to write a balancing script which would compare the column (AMT) of the same Balance ID and its corresponding step_keys and need your help with this.


My table data is as below:


BAL_ID, STEP_KEY, COMPANY, DAC, STATE, TYPE, AMT, PROC_DATE

1, 5, 1, 4, IL, PYMT, 54001.23, 2007-11-28

1, 2, 1, 4, IL, PYMT, 54001.24, 2007-11-28



2, 3, 1, 4, IL, RSV, 100.05, 2007-11-28

2, 4, 1, 4, IL, RSV, 100.25, 2007-11-28

2, 3, 1, 5, IL, PYMT, 2201, 2007-11-28

2, 4, 1, 5, IL, PYMT, 2201.5, 2007-11-28



Say for example: For every BAL_ID, there are two step_keys and I have to compare the AMT of these two steps keys and display them as AMT1 and AMT2 if they don't match.



For BAL_ID 1, I have to compare 540001.23 with 54001.24 for step keys 5 & 2 respectively.



Final output based on the above data should be like



BAL_ID COMPANY DAC STATE TYPE STEP_KEY1 AMT1 STEP_KEY2 AMT2 PROC_DATE

1 1 4 IL PYMT 5 54001.23 2 54001.24 2007-11-28

2 1 4 IL RSV 3 100.05 4 100.25 2007-11-28

2 1 5 il RSV 3 2201 4 2001.5 2007-11-28



Thanks,

Pinki
