describe-table

Description

Describes the detailed information about a table from metadata in the cluster. The information includes its columns. A token is returned to page through the column list. Depending on the authorization method, use one of the following combinations of request parameters:

• Secrets Manager - when connecting to a cluster, specify the Amazon Resource Name (ARN) of the secret, the database name, and the cluster identifier that matches the cluster in the secret. When connecting to a serverless workgroup, specify the Amazon Resource Name (ARN) of the secret and the database name.

• Temporary credentials - when connecting to a cluster, specify the cluster identifier, the database name, and the database user name. Also, permission to call the redshift:GetClusterCredentials operation is required. When connecting to a serverless workgroup, specify the workgroup name and database name. Also, permission to call the redshift-serverless:GetCredentials operation is required.

See ‘aws help’ for descriptions of global parameters.

describe-table is a paginated operation. Multiple API calls may be issued in order to retrieve the entire data set of results. You can disable pagination by providing the --no-paginate argument. When using --output text and the --query argument on a paginated response, the --query argument must extract data from the results of the following query expressions: ColumnList

Options

--cluster-identifier (string)

The cluster identifier. This parameter is required when connecting to a cluster and authenticating using either Secrets Manager or temporary credentials.

--connected-database (string)

A database name. The connected database is specified when you connect with your authentication credentials.

--database (string)

The name of the database that contains the tables to be described. If ConnectedDatabase is not specified, this is also the database to connect to with your authentication credentials.

--db-user (string)

The database user name. This parameter is required when connecting to a cluster and authenticating using temporary credentials.

--schema (string)

The schema that contains the table. If no schema is specified, then matching tables for all schemas are returned.

--secret-arn (string)

The name or ARN of the secret that enables access to the database. This parameter is required when authenticating using Secrets Manager.

--table (string)

The table name. If no table is specified, then all tables for all matching schemas are returned. If no table and no schema is specified, then all tables for all schemas in the database are returned

--workgroup-name (string)

The serverless workgroup name. This parameter is required when connecting to a serverless workgroup and authenticating using either Secrets Manager or temporary credentials.

--cli-input-json | --cli-input-yaml (string) Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, those values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally. This may not be specified along with --cli-input-yaml.

--starting-token (string)

A token to specify where to start paginating. This is the NextToken from a previously truncated response.

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--page-size (integer)

The size of each page to get in the AWS service call. This does not affect the number of items returned in the command’s output. Setting a smaller page size results in more calls to the AWS service, retrieving fewer items in each call. This can help prevent the AWS service calls from timing out.

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--max-items (integer)

The total number of items to return in the command’s output. If the total number of items available is more than the value specified, a NextToken is provided in the command’s output. To resume pagination, provide the NextToken value in the starting-token argument of a subsequent command. Do not use the NextToken response element directly outside of the AWS CLI.

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. Similarly, if provided yaml-input it will print a sample input YAML that can be used with --cli-input-yaml. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

See ‘aws help’ for descriptions of global parameters.

Output

ColumnList -> (list)

A list of columns in the table.

(structure)

The properties (metadata) of a column.

columnDefault -> (string)

The default value of the column.

isCaseSensitive -> (boolean)

A value that indicates whether the column is case-sensitive.

isCurrency -> (boolean)

A value that indicates whether the column contains currency values.

isSigned -> (boolean)

A value that indicates whether an integer column is signed.

label -> (string)

The label for the column.

length -> (integer)

The length of the column.

name -> (string)

The name of the column.

nullable -> (integer)

A value that indicates whether the column is nullable.

precision -> (integer)

The precision value of a decimal number column.

scale -> (integer)

The scale value of a decimal number column.

schemaName -> (string)

The name of the schema that contains the table that includes the column.

tableName -> (string)

The name of the table that includes the column.

typeName -> (string)

The database-specific data type of the column.

NextToken -> (string)

A value that indicates the starting point for the next set of response records in a subsequent request. If a value is returned in a response, you can retrieve the next set of records by providing this returned NextToken value in the next NextToken parameter and retrying the command. If the NextToken field is empty, all response records have been retrieved for the request.

TableName -> (string)

The table name.
