Re: using sql to crack packed decimal out of a char field

I have a packed(3,0) value embedded in an located at position 140 of a
256 char field. I am creating an sql view to crack all the values out
of that 256 char field. The char and zoned decimal values I can
isolate using sql substr.

The packed decimal values are another story. I am using HEX to give
me the data in hex external form. Then use substr to extract the
digit characters of the HEX output, excluding the final sign
character. Last step is use the DECIMAL to convert the HEX digits back
to a decimal value:
dec(substr(
hex(substr(a.cp960mstrp,140,2))
,1,3),3,0) ChgOff,

If there was a negative value in the original packed decimal value I
suppose CASE can be used on the final char of the HEX return value to
handle that.

Is there a more direct way in SQL of extracting packed decimal values
from character strings?
