How can i use Regex to get data from sqlite?


I want to search in a column that containing String like "I will have #dinner with @Akki on her #Bday.I am searching now like this but it's note working. while the variable search having value like #dinner. Thank you.

selectionArgs = new String[] {"'"+search+"'"}; String qur="SELECT * FROM TODOS WHERE fullnote REGEXP"; Cursor c = db.rawQuery(qur,selectionArgs);


Try using

String[] selectionArgs = new String[] {"%"+search+"%"}; Cursor c = db.rawQuery("SELECT * FROM TODOS WHERE fullnote LIKE ?",selectionArgs);

See <a href="http://developer.android.com/reference/android/database/sqlite/SQLiteDatabase.html#rawQuery(java.lang.String,%20java.lang.String[])" rel="nofollow">Android SQLite reference</a>:


public Cursor rawQuery (String sql, String[] selectionArgs)

selectionArgs - You may include ?s in where clause in the query, which will be replaced by the values from selectionArgs. The values will be bound as Strings.



selectionArgs = new String[] {search}; Cursor c = db.rawQuery("SELECT * FROM TODOS WHERE fullnote LIKE '%?%'",selectionArgs);


After long R&D i came to point that i can not use REGEXP directly. then i tried Cursor c = db.rawQuery("SELECT * FROM TODOS WHERE tag LIKE '%"+search+"%' ",null);

and it worked fine. Thanks everybody.
