Re: How to use like with a list

The example was a general case.  It won't be jo and mo and fo.  In fact, the values will be stored in a csv perl
scalar. 

If you know perl...

$str = "jo,mo,do,fo";

Using DBI, I need to "prepare" a query that will accept a string like the one above.

So...

select name,age,weight from people_table where name ~ '^(' || replace(?, ',', '|') || ')l'

but it doesn't work :-(


bi_dev=# create table test (name text);
CREATE TABLE
bi_dev=# insert into test (name) values ('jolly'),('frenchie'),('dollymadison');
INSERT 0 3
bi_dev=# select name from test where name ~ '^(' || replace('jo,mo,do,fo', ',', '|') || ')l';
ERROR:  argument of WHERE must be type boolean, not type text

ah, yeah, that.

and to complete the original requirement...

where field ~ '^(' || replace(?, ',', '|') || ')l'


btw, no need for a .* on the end, since the regex isn't anchored at the
end with a $
