LIST

Returns a list of files that have been staged (i.e. uploaded from a local file system or unloaded from a table) in one of the following Snowflake stages:

  • Named internal stage.

  • Named external stage.

  • Stage for a specified table.

  • Stage for the current user.

LIST can be abbreviated to LS.

Syntax

LIST { internalStage | externalStage } [ PATTERN = '<regex_pattern>' ]
Copy

Where:

internalStage ::=
    @[<namespace>.]<int_stage_name>[/<path>]
  | @[<namespace>.]%<table_name>[/<path>]
  | @~[/<path>]
Copy
externalStage ::=
    @[<namespace>.]<ext_stage_name>[/<path>]
Copy

Required parameters

internalStage | externalStage

Specifies the location where the data files are staged:

@[namespace.]int_stage_name[/path]

Files are in the specified named internal stage.

@[namespace.]ext_stage_name[/path]

Files are in the specified named external stage.

@[namespace.]%table_name[/path]

Files are in the stage for the specified table.

@~[/path]

Files are in the stage for the current user.

Where:

  • namespace is the database and/or schema in which the named stage or table resides. It is optional if a database and schema are currently in use within the session; otherwise, it is required.

  • path is an optional case-sensitive path for files in the cloud storage location (i.e. files have names that begin with a common string) that limits access to a set of files. Paths are alternatively called prefixes or folders by different cloud storage services.

Note

If the stage name or path includes spaces or special characters, it must be enclosed in single quotes (e.g. '@"my stage"' for a stage named "my stage").

Tip

Specifying a path provides a scope for the LIST command, potentially reducing the amount of time required to run the command.

Optional parameters

PATTERN = 'regex_pattern'

Specifies a regular expression pattern for filtering files from the output. The command lists all files in the specified path and applies the regular expression pattern on each of the files found.

Usage notes

  • In contrast to named stages, table and user stages are not first-class database objects; rather, they are implicit stages associated with the table/user. As such, they have no grantable privileges of their own:

    • You can always list files in your user stage (i.e. no privileges are required).

    • To list files in a table stage, you must use a role that has the OWNERSHIP privilege on the table.

Output

The command returns the following columns:

Column

Data type

Description

name

VARCHAR

Name of the staged file.

size

NUMBER

Size of the file compressed (in bytes).

md5

VARCHAR

The MD5 column stores an MD5 hash of the contents of the staged data file.

For internal stages with default encryption (SNOWFLAKE_FULL), during upload the source file is encrypted with a random key, and its resulting MD5 digest will always differ from the original local file.

Amazon S3 stages report the value via the S3 eTag field, which might not be an MD5 hash of the file contents.

For Google Cloud stages that use a customer-managed encryption key (CMEK), md5 is expected to be NULL.

For more information, see Customer-managed encryption keys.

last_modified

VARCHAR

Timestamp when the file was last updated in the stage.

Examples

List all the files in the stage for the mytable table:

LIST @%mytable;
Copy

List all the files in the path1 path of the mystage named stage:

LIST @mystage/path1;
Copy

List the files that match a regular expression (i.e. all file names containing the string data_0) in the stage for the mytable table:

LIST @%mytable PATTERN='.*data_0.*';
Copy

List the files in the /analysis/ path of the my_csv_stage named stage that match a regular expression (i.e. all file names containing the string data_0):

LIST @my_csv_stage/analysis/ PATTERN='.*data_0.*';
Copy

Use the abbreviated form of the command to list all the files in the stage for the current user:

LS @~;
Copy
