Question

I’ve a problem with LIKE operator in PostgreSQL. It does not match patterns that contain the - character. I’ve tried to escape these characters using the ESCAPE option, but it still does not work.

Query:

select * from footable where trascrizione like '% [---]is Abraam %';

Sample data (contents of column trascrizione):

[---]is Abraam [e]t Ise[---] / ((crux quadrata))

How can I solve this problem?

Answer 1

That pattern would not match because there is no space before [---]is Ambraam. There is a space in your pattern, between the % and [ characters, and it’s requiring that space to be in your data. Try LIKE '%[---]is Abraam %'.
