I am working on IBMi where whole number and fraction is represented by comma instead of decimal point (eg: 123,45 instead of 123.45)

This seem to be causing SQL functions to fail

Example:

 SUBSTR(MySTRING,1,1)

 SQL0104  30      12  Position 1 Token ,1 was not valid. Valid tokens: ) ,.  

STRSQL provides a session value for this (Decimal point = *Comma, *Period, *Job…)

Is there header value or environment value for SQL Stored Procedures that would make a decimal and commas behave as US/UK users expect?
