 ## Usage
 
 You need to use [RdbStore.query()](js-apis-data-rdb.md#query) to obtain a **resultSet** object.
 
 ```js
 import dataRdb from '@ohos.data.rdb';
-let predicates = new dataRdb.RdbPredicates("EMPLOYEE")
-predicates.equalTo("AGE", 18)
-let promise = rdbStore.query(predicates, ["ID", "NAME", "AGE", "SALARY", "CODES"])
+let predicates = new dataRdb.RdbPredicates("EMPLOYEE");
+predicates.equalTo("AGE", 18);
+let promise = rdbStore.query(predicates, ["ID", "NAME", "AGE", "SALARY", "CODES"]);
 promise.then((resultSet) => {
     console.log(TAG + "resultSet columnNames:" + resultSet.columnNames);
-    console.log(TAG + "resultSet columnCount:" + resultSet.columnCount);})
+    console.log(TAG + "resultSet columnCount:" + resultSet.columnCount);
+});
 ```
 
 ## ResultSet
