PostgreSQL equivalent to MySQL LOCATE()

[zerogreen]

Hi

I am looking for an equivalent to the LOCATE function from MySQL.
I have a query(PHP) that looks like this:

$query="SELECT * FROM table WHERE LOCATE('".$var."', field)> 0 ORDER BY LOCATE('".$var."', field) LIMIT 10";

Any Ideas?

I do not know mysql, but does LOCATE work as regular expressions. If so u can use postgres LIKE (or ILIKE) statement.

This may be a little late, but if I got here from a Google search, other people will, too. So here's an answer:

MySQL locate('substring','long string containing substring')
is equivalent to
PostgreSQL position('substring' IN 'long string containing substring')

I am having a similar problem.

However I wish to use this form:
LOCATE(substr,str,pos)

Can someone offer me a way too do this in postgresql?
(as 'position' does not contain the 'pos' function)

Thanks.

You can use

strpos(string, substring)
 

but it takes only two arguments.

You can use strpos with substr and it works lile locate

locate(to_find,str,pos)=strpos(substr(str,pos),to_find)
