I use pg-promise@8.4.4 and I would like to have wildcard characters and the unaccent function of the PostgreSQL.

My pl/pgsql query has something like

WHERE unaccent(p.name) ILIKE (''%'' || unaccent($1) || ''%'')'

I want to make it into a pg-promise query like

uniqueQuery('select id, name from place WHERE unaccent(name) ILIKE \'% unaccent($1) #%\' ', [name])

Without the unaccent it works fine. When I add the unaccent , I get a synta error : error: syntax error at or near "ονομα μερους" (ονομα μερους is an the string I am searching for).

How can I combine the wildcards with the unaccent ?

Thanks

    If you can work out an example that works within pgAdmin, then it will be possible to advise how to change it for `pg-promise` query formatting. Without such an example it is not clear whether the issue is with your SQL or the query formatting. – vitaly-t Jul 15 '18 at 18:12
  • If I understand what you ask, this works : `uniqueQuery('select id, name from place WHERE name ILIKE \'%$1)#%\' ', [name])`. If I search for something with tones I get nothing and I should, this is why I need the `unaccent` (`όνομα μέρους` is the same as `ονομα μερους` , but the first has tones and gives back nothing) . Also, a SQL simpler query that works with `unaccent` is this `SELECT p.id, p.name, p.geom FROM place p WHERE unaccent(p.name) ILIKE unaccent('%κοιλαδα%') ;` . Thanks – slevin Jul 15 '18 at 18:30

    Then you should use `ILIKE unaccent(\'%$1#%\')`, which is the same as `ILIKE unaccent(\'%$1:value%\')`. See the [Open Values](https://github.com/vitaly-t/pg-promise#open-values) syntax. – vitaly-t Jul 15 '18 at 18:32
  • Thanks. My angular just flopped,I will debug angular and test your suggestion and let you know. – slevin Jul 15 '18 at 18:35
  • @vitaly-t Hi again. This is not working. If I do `unaccent(name)`, the results have the name data with an `unaccent` name, not a `name` name. In simpler terms, look : the result is `{ id: '3', unaccent: 'κοιλαδα' }` but it should be `{ id: '3', name: 'κοιλαδα' }` – slevin Jul 16 '18 at 15:04
  • Also all the results are unaccent. In simple SQL the results are accent, they have tones etc. but with this approach they end up unaccent. – slevin Jul 16 '18 at 15:05

    Use `as.format(query, values)` to get the resulting string without executing it, and then see what is wrong with the SQL, then we can figure out how to fix the formatting for it. Otherwise, it is all blind guessing. – vitaly-t Jul 16 '18 at 15:07
  • Thanks. Working on it. – slevin Jul 16 '18 at 15:09
  • This is the string, that `as.format` gives back : `select id, unaccent(name) from place WHERE name ILIKE unaccent('%κ%')` . I might be wrong, but this looks normal to me. All the problems remain. Unaccent removes all tones and if I search with tones I still cannot find anything, because I guess unaccent removed them ? Sorry, I am out of ideas, but I am willing to help you . So, anything you need, tell me. – slevin Jul 16 '18 at 15:20
  • You should diagnose the result SQL in pgAdmin, and then fix the formatting as required. – vitaly-t Jul 16 '18 at 15:26

    Ah, the query should be generalQuery('select id, name from place WHERE unaccent(name) ILIKE unaccent(\'%$1#%\') ', [name]). The `unaccent` must go in the WHERE, not the SELECT part. Now it works fine. I am so sorry for wasting your time vitaly. You are a good and helpful developer. Feel free to turn your comments to an answer, so I can upvote and choose as accepted. Thanks I'm gonna go and hit a brick wall with my head now. – slevin Jul 16 '18 at 15:35
