How to write WHERE IN clause from a dynamic ArrayList for Android SQLite query
You can use the Android TextUtils class join method to make a comma separated list of IDs to put in the in clause.
String selection = KEY_GROUP_ID + " IN (" + TextUtils.join(", ", groupIds) + ")";
return db.query(TABLE_CUSTOMERS, new String[] { KEY_CUSTOMER_ID, KEY_NAME}, selection, null, null, null, null);
BTW if groupIds is a list of primary keys from another table you should be using Longs to store them not Integers otherwise it will overflow when the IDs get large.
return db.query(TABLE_CUSTOMERS, new String[] { KEY_CUSTOMER_ID, KEY_NAME }, KEY_GROUP_ID + " >=" + groupIdsLowLimit + " and " + KEY_GROUP_ID + " <=" + groupIdsUpLimit, null, null, null, null);
String where = "";
for (int i = 0; i < list.size(); i++) {
where = where + KEY_GROUP_ID + " =" + list.get(i).toString() + "";
if (i != (list.size() - 1))
where = where + " or";
}
return db.query(TABLE_CUSTOMERS, new String[] { KEY_CUSTOMER_ID, KEY_NAME }, where, null, null, null, null);
