Using SIMILAR TO for a regex?

Question

Why is the following instruction returning FALSE?

SELECT \'[1-3]{5}\' SIMILAR TO \'22222\' ;

I can\'t find what is wrong with that

Answer 1

The operator is defined as:

string SIMILAR TO pattern 

so the first parameter is the string that you want to compare. The second parameter is the regex to compare against.

You need:

SELECT '22222' SIMILAR TO '[1-3]{5}';
