# Table Functions
|
||
|
||
Table functions are methods for constructing tables.
|
||
|
||
You can use table functions in:
|
||
|
||
- [FROM](../../sql-reference/statements/select/from.md) clause of the `SELECT` query.
|
||
|
||
The method for creating a temporary table that is available only in the current query. The table is deleted when the query finishes.
|
||
|
||
- [CREATE TABLE AS table_function()](../../sql-reference/statements/create/table.md) query.
|
||
|
||
It's one of the methods of creating a table.
|
||
|
||
- [INSERT INTO TABLE FUNCTION](../../sql-reference/statements/insert-into.md#inserting-into-table-function) query.
|
||
|
||
:::note
|
||
You can’t use table functions if the [allow_ddl](../../operations/settings/permissions-for-queries.md#settings_allow_ddl) setting is disabled.
