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>
}
]
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
withoutdb_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-qualifiedschema_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.

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