SHOW FILE FORMATS¶

Lists the file formats for which you have access privileges. This command can be used to list the file formats for a specified database or schema (or the current database/schema for the session), or your entire account.

Syntax

SHOW FILE FORMATS [ LIKE '<pattern>' ]
                  [ IN
                       {
                          ACCOUNT                                         |

                          DATABASE                                        |
                          DATABASE <database_name>                        |

                          SCHEMA                                          |
                          SCHEMA <schema_name>                            |
                          <schema_name>

                          APPLICATION <application_name>                  |
                          APPLICATION PACKAGE <application_package_name>  |
                       }
                  ]

Parameters¶

LIKE 'pattern'

Optionally filters the command output by object name. The filter uses case-insensitive pattern matching, with support for SQL wildcard characters (% and _).

For example, the following patterns return the same results:

... LIKE '%testing%' ...

... LIKE '%TESTING%' ...

. Default: No value (no filtering is applied to the output).

[ IN ... ]

Optionally specifies the scope of the command. Specify one of the following:

ACCOUNT

Returns records for the entire account.

DATABASE, . DATABASE db_name

Returns records for the current database in use or for a specified database (db_name).

If you specify DATABASE without db_name and no database is in use, the keyword has no effect on the output.

Note

Using SHOW commands without an IN clause in a database context can result in fewer than expected results.

Objects with the same name are only displayed once if no IN clause is used. For example, if you have table t1 in schema1 and table t1 in schema2, and they are both in scope of the database context you’ve specified (that is, the database you’ve selected is the parent of schema1 and schema2), then SHOW TABLES only displays one of the t1 tables.

SCHEMA, . SCHEMA schema_name

Returns records for the current schema in use or a specified schema (schema_name).

SCHEMA is optional if a database is in use or if you specify the fully qualified schema_name (for example, db.schema).

If no database is in use, specifying SCHEMA has no effect on the output.

APPLICATION application_name, . APPLICATION PACKAGE application_package_name: Returns records for the named Snowflake Native App or application package.

Default: Depends on whether the session currently has a database in use:

Database: DATABASE is the default (that is, the command returns the objects you have privileges to view in the database).
No database: ACCOUNT is the default (that is, the command returns the objects you have privileges to view in your account).

Output¶

The command output provides file format properties and metadata in the following columns:

Column	Description
format_options	Values of all options for the file format type. Returns the default value for any option that is not explicitly defined.
created_on	Date and time when the database was created.
name	Name of the file format.
database_name	Database in which the file format is stored.
schema_name	Schema in which the file format is stored.
type	File format type: CSV, JSON, Avro, ORC, Parquet, or XML.
owner	Role that owns the file format.
comment	Comment for the database.
owner_role_type	The type of role that owns the object, for example `ROLE`. . If a Snowflake Native App owns the object, the value is `APPLICATION`. . Snowflake returns NULL if you delete the object because a deleted object does not have an owner role.

Usage notes¶

The output of this command might include objects with names like SN_TEMP_OBJECT_<n> (where <n> is a number). These are temporary objects that are created by the Snowpark library on behalf of the user.

The command doesn’t require a running warehouse to execute.
The command only returns objects for which the current user’s current role has been granted at least one access privilege.
The MANAGE GRANTS access privilege implicitly allows its holder to see every object in the account. By default, only the account administrator (users with the ACCOUNTADMIN role) and security administrator (users with the SECURITYADMIN role) have the MANAGE GRANTS privilege.

To post-process the output of this command, you can use the RESULT_SCAN function, which treats the output as a table that can be queried.

The command returns a maximum of ten thousand records for the specified object type, as dictated by the access privileges for the role used to execute the command. Any records above the ten thousand records limit aren’t returned, even with a filter applied.

To view results for which more than ten thousand records exist, query the corresponding view (if one exists) in the Snowflake Information Schema.
