SHOW DYNAMIC TABLES¶

Syntax¶

SHOW DYNAMIC TABLES [ LIKE '<pattern>' ]
                    [ IN
                      {
                           ACCOUNT              |

                           DATABASE             |
                           DATABASE <db_name>   |

                           SCHEMA               |
                           SCHEMA <schema_name> |
                           <schema_name>
                      }
                    ]
                    [ STARTS WITH '<name_string>' ]
                    [ LIMIT <rows> [ FROM '<name_string>' ] ]

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).

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¶

• To SHOW a dynamic table, you must be using a role that has MONITOR privilege on the table.

• 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.

Output¶

The command output provides table properties and metadata in the following columns:

Examples¶

Show all the dynamic tables with names that start with product_ in the mydb.myschema schema:

SHOW DYNAMIC TABLES LIKE 'product_%' IN SCHEMA mydb.myschema;
