Then write a RPG function that converts the character string into a numeric
value using %DEC.
If the function crashes return 0 else 1.
Register this RPG function as SQL UDF and use it!

No, you only can check for numeric values by translating all digits

*Blank.
This is a nice and simple method for "well behaved" data, but has
limitations. For example, it will also consider '123.4.5.6' and '12
.3 4....' to be numeric values. It also doesn't handle negative
numbers or scientific notation, which may or may not be relevant.
The lack of an IsNumeric function is a common complaint. See this article

tl;dr: Create a UDF. You'll probably need it over and over again anyway,
so in the long run you'll be glad you did.
