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).
The owner and owner_role_type columns don’t return a value.
The command doesn’t require a running warehouse to execute.
The command only returns objects for which the current user’s current role has been granted at least one access privilege.
The MANAGE GRANTS access privilege implicitly allows its holder to see every object in the account. By default, only the account administrator (users with the ACCOUNTADMIN role) and security administrator (users with the SECURITYADMIN role) have the MANAGE GRANTS privilege.
To post-process the output of this command, you can use the pipe operator (->>) or the RESULT_SCAN function. Both constructs treat the output as a result set that you can query.
The output column names for this command are generated in lowercase. If you consume a result set from this command with the pipe operator or the RESULT_SCAN function, use double-quoted identifiers for the column names in the query to ensure that they match the column names in the output that was scanned. For example, if the name of an output column is type, then specify "type" for the identifier.
The value for LIMIT rows can’t exceed 10000. If LIMIT rows is omitted, the command results in an error if the result set is larger than ten thousand rows.
To view results for which more than ten thousand records exist, either include LIMIT rows or query the corresponding view in the Snowflake Information Schema.
