## Writing To Hive
-Similarly, data can be written into hive using an `INSERT INTO` clause.
+Similarly, data can be written into hive using an `INSERT` clause. Consider
there is a mytable table with two columns: name, age.
{% highlight bash %}
-Flink SQL> INSERT INTO mytable (name, value) VALUES ('Tom', 4.72);
+# -- Insert with append mode --
+Flink SQL> INSERT INTO mytable SELECT 'Tom', 25;
+
+# -- Insert with overwrite mode --
+Flink SQL> INSERT OVERWRITE mytable SELECT 'Tom', 25;
+{% endhighlight %}

+We support partition table too, Consider there is a myparttable table with
four columns: name, age, my_type and my_date. Column my_type and column my_date
are the partition columns.
+
+{% highlight bash %}
+# -- Insert with static partition --
+Flink SQL> INSERT OVERWRITE myparttable PARTITION (my_type='type_1',
my_date='2019-08-08') SELECT 'Tom', 25;
+
+# -- Insert with dynamic partition --
+Flink SQL> INSERT OVERWRITE myparttable SELECT 'Tom', 25, 'type_1',
'2019-08-08';
+
+# -- Insert with static(my_type) and dynamic(my_date) partition --
+Flink SQL> INSERT OVERWRITE myparttable PARTITION (my_type='type_1') SELECT
'Tom', 25, '2019-08-08';
{% endhighlight %}
## Formats
We have tested on the following of table storage formats: text, csv,
SequenceFile, ORC, and Parquet.
