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.

See also:

CREATE FILE FORMAT , DROP FILE FORMAT , ALTER FILE FORMAT , DESCRIBE FILE FORMAT

Syntax

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

                          DATABASE                 |
                          DATABASE <database_name> |

                          SCHEMA                   |
                          SCHEMA <schema_name>     |
                          <schema_name>
                       }
                  ]
Copy

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.

SCHEMA, . SCHEMA schema_name, . 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.

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).

Usage Notes¶

  • Columns that start with the prefix is_ return either Y (yes) or N (no).

  • The command does not require a running warehouse to execute.

  • The command returns a maximum of 10K records for the specified object type, as dictated by the access privileges for the role used to execute the command; any records above the 10K limit are not returned, even with a filter applied.

    To view results for which more than 10K records exist, query the corresponding view (if one exists) in the Snowflake Information Schema.

  • 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 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.

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, either ROLE or DATABASE_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.
