ARGSIZE2

The ARGSIZE2 global variable stores the second size for arguments that have a size. For example, if the fourth argument's data type was NUMERIC(18,4), then ARGSIZE1[4] would be equal to 18 and ARGSIZE2[4] would be equal to 4.

Arguments that do not have a second size value such as a varchar, date, or an integer have an ARGSIZE2 value of negative one.
