I am trying to create a query which will fetch me rows which has matching values between 2 columns. Column 1 is declared as DECIMAL(17) and Column 2 is CHAR 15. I tried CAST and SUBSTR but end up with -104. Let me know how to approach this problem.
Of course you will get the sqlcode -420.
Why are you comparing alphanumeric to decimal? This is wrong at first place and still if you want to go ahead then you should either skip the one with alphanumeric or remove alphabets from the alphanumeric part and then compare. You need to explain better what do you want to achieve to get moving further.
Please learn to use code tags.

try the other direction, try to convert numeric values in alphanumerics:
Use CAST(col1 AS VARCHAR(17)) (i.e. 123 would be converted in '123') or DIGITS(col1) (i.e. 123 would be converted in '0000000123' or something similar)...
