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.

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'

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%' ...
[ 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 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 (e.g. 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 (i.e. the command returns the objects you have privileges to view in the database).

  • No database: ACCOUNT is the default (i.e. the command returns the objects you have privileges to view in your account).

Usage Notes

  • 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 primary and secondary database properties and metadata in the following columns:

| format_options | created_on | name | database_name | schema_name | type | owner | comment |
Copy

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. Note that Snowflake returns NULL if you delete the object because there is no owner role for a deleted object.
