I have a float column that I need to search with LIKE /using of course some kind of string cast). The problem is that DB2 float to string cast, casts to scientific notation. I have tried casting to a decimal first, this helps, but pads the LHS with 0s. This causes problem when the numbers are negative. I have a column with the following value '-129.543'. I would like to be able to search with the following examples:
select char(decimal(wkz, 12, 4)) from lst.klk where char(decimal(wkz, 12, 4)) like '%129.5%'
works for all examples except those with a minus sign.
