Detailed Description

A set of parameters for Kinetica.showTable.

Retrieves detailed information about a table, view, or schema, specified in table_name. If the supplied table_name is a schema the call can return information about either the schema itself or the tables and views it contains. If 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 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.).

Constructor & Destructor Documentation

◆ ShowTableRequest() [1/2]

kinetica.ShowTableRequest.ShowTableRequest ( )

inline

Constructs a ShowTableRequest object with default parameters.

Definition at line 316 of file ShowTable.cs.

◆ ShowTableRequest() [2/2]

kinetica.ShowTableRequest.ShowTableRequest	(	string	table_name,
		IDictionary< string, string >	options = `null`
	)

inline

Constructs a ShowTableRequest object with the specified parameters.

Parameters

table_name Name of the table for which to retrieve the information, in [schema_name.]table_name format, using standard name resolution rules. If blank, then returns information about all tables and views.

options

Optional parameters.

DEPENDENCIES: Include view dependencies in the output. Supported values:
- TRUE
- FALSE
The default value is FALSE.
FORCE_SYNCHRONOUS: If TRUE then the table sizes will wait for read lock before returning. Supported values:
- TRUE
- FALSE
The default value is TRUE.
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 occuring. Supported values:
- TRUE
- FALSE
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:
- TRUE
- FALSE
The default value is FALSE.
NO_ERROR_IF_NOT_EXISTS: If FALSE will return an error if the provided table_name does not exist. If TRUE then it will return an empty result. Supported values:
- TRUE
- FALSE
The default value is FALSE.
SHOW_CHILDREN: If 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 table_name is a table or view, SHOW_CHILDREN must be FALSE. If table_name is empty, then SHOW_CHILDREN must be TRUE. Supported values:
- TRUE
- FALSE
The default value is TRUE.
GET_COLUMN_INFO: If TRUE then column info (memory usage, etc) will be returned. Supported values:
- TRUE
- FALSE
The default value is FALSE.

The default value is an empty Dictionary.
