How do I check if a string contains a number

Question

I need to check if a string contains a number. Any number. Not wether or not the string IS a number, but if it contains one.

Examples:

\'test\' = no numbers.

Answer 1

I sometimes use REGEXP_INSTR in NetSuite saved searches since the SQL functions are limited. It returns a zero if no numbers are found, or the starting position of the first number found in the string:

REGEXP_INSTR(my_var, '[[:digit:]]')

This example returns zero:

REGEXP_INSTR('test', '[[:digit:]]')

This example returns a number greater than zero since it found a number:

REGEXP_INSTR('test2', '[[:digit:]]')
