Detailed Description
A set of parameters for Kinetica.showTable.
Retrieves detailed information about a table, view, or schema, specified in ShowTableRequest.table_name. If the supplied ShowTableRequest.table_name is a schema the call can return information about either the schema itself or the tables and views it contains. If ShowTableRequest.table_name is empty, information about all schemas will be returned.
If the option GET_SIZES is set to TRUE, then the number of records in each table is returned (in sizes and full_sizes), along with the total number of objects across all requested tables (in total_size and total_full_size).
For a schema, setting the SHOW_CHILDREN option to FALSE returns only information about the schema itself; setting SHOW_CHILDREN to TRUE returns a list of tables and views contained in the schema, along with their corresponding detail.
To retrieve a list of every table, view, and schema in the database, set ShowTableRequest.table_name to ’*’ and SHOW_CHILDREN to TRUE. When doing this, the returned total_size and total_full_size will not include the sizes of non-base tables (e.g., filters, views, joins, etc.).

Property Documentation
◆ options
| getset |
Optional parameters.
- DEPENDENCIES: Include view dependencies in the output. Supported values:The default value is FALSE.
- FORCE_SYNCHRONOUS: If TRUE then the table sizes will wait for read lock before returning. Supported values:The default value is TRUE.
- GET_ACCESS_DATA: If TRUE then data about the last read, write, alter and create will be returned. Supported values:The default value is FALSE.
- GET_CACHED_SIZES: If TRUE then the number of records in each table, along with a cumulative count, will be returned; blank, otherwise. This version will return the sizes cached at rank 0, which may be stale if there is a multihead insert occurring. Supported values:The default value is FALSE.
- GET_SIZES: If TRUE then the number of records in each table, along with a cumulative count, will be returned; blank, otherwise. Supported values:The default value is FALSE.
- REFERENCING_MATERIALIZED_VIEWS: Include materialized views using this table as a source in the output. Supported values:The default value is FALSE.
- SKIP_ADDITIONAL_INFO: If TRUE then the response will not populate the additional_info field. Supported values:The default value is FALSE.
- NO_ERROR_IF_NOT_EXISTS: If FALSE will return an error if the provided ShowTableRequest.table_name does not exist. If TRUE then it will return an empty result. Supported values:The default value is FALSE.
- SKIP_TEMP_SCHEMAS: If TRUE then the table list will not include tables from SYS_TEMP and other system temporary schemas. This is the default behavior for non-admin users. Supported values:The default value is FALSE.
- SHOW_CHILDREN: If ShowTableRequest.table_name is a schema, then TRUE will return information about the tables and views in the schema, and FALSE will return information about the schema itself. If ShowTableRequest.table_name is a table or view, SHOW_CHILDREN must be FALSE. If ShowTableRequest.table_name is empty, then SHOW_CHILDREN must be TRUE. Supported values:The default value is TRUE.
- GET_COLUMN_INFO: If TRUE then column info (memory usage, etc) will be returned. Supported values:The default value is FALSE.
The default value is an empty Dictionary.
