+# Insert Just The Defaults
+
+If you are constructing an `INSERT` statement for a table whose required
+columns all have default values, you may just want to use the defaults. In
+this situation, you can break away from the standard:
+
+```
+> insert into table_name (column1, column2) values (value1, value2);
+```
+
+Instead, simply tell Postgres that you want it to use the default values:
+
+```
+> insert into table_name default values;
+```
