Syntax

SHOW CLASSES [ LIKE '<pattern>' ]
             [ IN DATABASE [ <db_name> ] ]
             [ LIMIT <rows> [ FROM '<name_string>' ] ]
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 DATABASE db_name

Specifies the scope of the command, which determines whether the command lists records only for the current/specified database or across your entire account.

The DATABASE keyword is not required; you can set the scope by specifying only the database name. Likewise, the database name is not required if the session currently has a database in use.

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).

STARTS WITH 'name_string'

Optionally filters the command output based on the characters that appear at the beginning of the object name. The string must be enclosed in single quotes and is case-sensitive.

For example, the following strings return different results:

... STARTS WITH 'B' ...
... STARTS WITH 'b' ...

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

LIMIT rows [ FROM 'name_string' ]

Optionally limits the maximum number of rows returned, while also enabling “pagination” of the results. The actual number of rows returned might be less than the specified limit. For example, the number of existing objects is less than the specified limit.

The optional FROM 'name_string' subclause effectively serves as a “cursor” for the results. This enables fetching the specified number of rows following the first row whose object name matches the specified string:

  • The string must be enclosed in single quotes and is case-sensitive.

  • The string does not have to include the full object name; partial names are supported.

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

Note

For SHOW commands that support both the FROM 'name_string' and STARTS WITH 'name_string' clauses, you can combine both of these clauses in the same statement. However, both conditions must be met or they cancel out each other and no results are returned.

In addition, objects are returned in lexicographic order by name, so FROM 'name_string' only returns rows with a higher lexicographic value than the rows returned by STARTS WITH 'name_string'.

For example:

  • ... STARTS WITH 'A' LIMIT ... FROM 'B' would return no results.

  • ... STARTS WITH 'B' LIMIT ... FROM 'A' would return no results.

  • ... STARTS WITH 'A' LIMIT ... FROM 'AB' would return results (if any rows match the input strings).

Usage Notes

  • The owner and owner_role_type columns do not return a value.

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

  • The value for LIMIT rows cannot exceed 10000. If LIMIT rows is omitted, the command results in an error if the result set is larger than 10K rows.

    To view results for which more than 10K records exist, either include LIMIT rows or query the corresponding view 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.
