Android中sqlite3中的多个where子句

Question

I'm struggling with sqlite query since 2 days in Android.

Here is details -

I've two table

1. localeResource

2. Banner table

Table structure is -

LocalResource - id, locale, key, value

Banner - bannerid, bannername, bannerimage, bannerlink, bannertext, countryid, bannerassociate

My query is like -

Working query -

select ban.bannerid,loc.value,ban.bannerimage,ban.bannerlink,ban.bannertext,ban.countryid,ban.bannerassociatedstyle from banner ban left outer join localeResources  loc on  loc.key = ban.bannername and loc.locale='FR';

But I wanted query like -

select ban.bannerid,loc.value,ban.bannerimage,ban.bannerlink,locs.value,ban.countryid,ban.bannerassociatedstyle from banner ban left outer join localeResources  loc, localeResources  locs on  loc.key = ban.bannername, locs.key = ban.bannertext and loc.locale='FR';

When I'm running second query my sqlite is hanging and crashing.

Please let me know what & where i'm missing.

Answer 1

Your query is wrong:

This one should work:

    select ban.bannerid,loc.value,ban.bannerimage,ban.bannerlink,locs.value,ban.countryid,ban.bannerassociatedstyle 
   from banner ban left outer join localeResources  loc on loc.key = ban.bannername and loc.locale='FR'
   left outer join localeResources  locs on  locs.key = ban.bannertext ;

You have the on statement at the wrong place.

Answer 2

Thanks Jens, based on your query, correct query is -

select ban.bannerid,loc.value,ban.bannerimage,ban.bannerlink,locs.value,ban.countryid,ban.bannerassociatedstyle from banner ban 
left outer join localeResources  loc on loc.key = ban.bannername and loc.locale='FR' left outer join localeResources  locs on  locs.key = ban.bannertext 
and locs.locale='FR';";
