Select Query In Sqlite Android
String temp_address='nothing'; try { String selectQuery = 'SELECT lastchapter FROM Bookdetails INTO'+temp_address+'WHERE bookpath=?'; db.execSQL(selectQuery
Solution 1:
There are SQL syntax problems and you'll need to use a Cursor
to retrieve query results, for example with rawQuery()
:
StringselectQuery="SELECT lastchapter FROM Bookdetails WHERE bookpath=?";
Cursorc= db.rawQuery(selectQuery, newString[] { fileName });
if (c.moveToFirst()) {
temp_address = c.getString(c.getColumnIndex("lastchapter"));
}
c.close();
Solution 2:
The logcat said it all, you've forgot spaces. To get data into the string:
String temp_address="nothing";
String[] args = newString[] { fileName };
Cursor cursor = sqLiteDatabase.rawQuery("SELECT lastchapter FROM Bookdetails WHERE bookpath=?", args);
if (cursor.moveToFirst()){
temp_address = cursor.getString(cursor.getColumnIndex("lastchapter"));
}
cursor.close();
Solution 3:
Correct your query with below: add space at WHERE
Cause
StringselectQuery="SELECT lastchapter FROM Bookdetails WHERE bookpath=? ";
Update: go with rawQuery()
becoz it's return Cursor
with results
StringselectQuery="SELECT lastchapter FROM Bookdetails WHERE bookpath=? ";
Cursorc= db.rawQuery(selectQuery, newString[] { fileName });
if (c.moveToFirst()) {
temp_address = c.getString(0);
}
c.close();
