I am using Sugar ORM, which is actually a library for SQL database operation. My database has over 4000 records, and I would like to retrieve 500 records from it, say the 501th to 1000th record.
The extraction of 500 records are as follows:
db_record_listing = Records.findWithQuery(Records.class, "Select * FROM Records ORDER BY recordId ASC WHERE qref_canton BETWEEN '" + s_start + "' AND '" + s_end + "'");
However, the error logcat is as follows:
11-25 23:29:35.639: E/AndroidRuntime(28801): Caused by: android.database.sqlite.SQLiteException: near "WHERE": syntax error (code 1): , while compiling: Select * FROM Records ORDER BY recordId ASC WHERE qref_canton BETWEEN '1' AND '500'

recordId
within the range and thereby very slow? If yes, would there be a quicker way where system would only retrieve those 500 records and no more?Select * FROM Records WHERE qref_canton BETWEEN '1' AND '500' ORDER BY recordId ASC
