Question

name = namebox.getText().toString();
db.open();
Cursor c1 = db.executequery("SELECT _id FROM " + DATABASE_TABLE_CUSTOMER + " where name='" +name+"'" );
_id = c1.getInt(c1.getColumnIndex("name"));
Cursor c2 = db.executequery("SELECT amount FROM " + DATABASE_TABLE_CUSTOMER
        +
        " where _id=" + _id);
Double amount = c2.getDouble(c2.getColumnIndex("amount"));
Cursor c3 = db.executequery("SELECT arrear FROM " + DATABASE_TABLE_CUSTOMER + " where CUSTOMER_ID =" + _id);
arrear = c3.getDouble(c3.getColumnIndex("arrear"));
db.close();

This is giving me a bad request for field error. The method executequery on my adapter looks like this:

public Cursor executequery(String query) throws SQLException
{
    Cursor mCursor = db.rawQuery(query, null);
    if(mCursor != null){
        mCursor.moveToFirst();
    }
    return mCursor;
}

Can anyone please tell me what Im doing wrong. Im new at this.

You are being inconsistent when dealing with Cursor1. getColumnIndex("name") cannot succeed because IDs, not names are being SELECTed. It should read getColumnIndex("_id").
