SQLite .query() method, WHERE clause is only taking double quotes strings

Question

I have variable:

String owner=\"Mike\";
String[] columns ={\"quantity\", \"price\",\"owner\"}

My cursor is trying to get
Curso

Answer 1

the simplest way is to use SELECT col1,col2 FROM table_name WHERE col =' something' ; just like Leandros said , my problem was the single quotes , thnx

Answer 2

SELECT quantity, price, owner, FROM sku_table WHERE owner='Mike' this is the correct SELECT. You forget the ' ' (single quotes)

Answer 3

Cursor findEntry = db.query("sku_table", columns, "owner='"+owner+"'", null, null, null, null);

Answer 4

 public Cursor show_vol(String  vol,String bk,String hadnu)
           { 
              SQLiteDatabase db = this.getReadableDatabase();
              String[] columns ={"hadith"};//colums name that you select

              Cursor res = db.query("volume2", columns, "hadithno=?", new String[] { hadnu }, null, null, null);

 //volume2 is table name  and hadithno is colume name  l
//select hadith from volume2 where hadithno=hadnu  //working like s

 1. List item

              return res;
           }

Answer 5

Sorry, but that is exactly the reason why you should work with what the method offers! @Leandros and @Jake are helping in the totally wrong direction! Sorry to say that...

The only solution you should use is this:

Cursor findEntry = db.query("sku_table", columns, "owner=?", new String[] { owner }, null, null, null);

ps: Yes I down voted both answers as they may work but providing a solution that shouldn't be used.

Update:

If you need more than one where condition, just add it like you would do in a normal query

Cursor findEntry = db.query("sku_table", columns, "owner=? and price=?", new String[] { owner, price }, null, null, null);

The order of the ? and the new String[] {...} elements must be the same!

Answer 6

I know this is an old question, but you can also do it like this:

Cursor findEntry = db.query("sku_table", columns, "owner=\'"+owner+"\'", null, null, null, null);

I just did it in my app and it worked as expected.

Jake's answer was similar, but probably wouldn't work without the \ before the '
