Create Table

  • Artikkeli

The Create Table operation creates a new table in a storage account.

Request

You can construct the Create Table request as shown here. We recommend that you use HTTPS. Replace myaccount with the name of your storage account:

Method Request URI HTTP version
POST https://myaccount.table.core.windows.net/Tables HTTP/1.1

Emulated storage service request

When you're making a request against the emulated storage service, specify the emulator hostname and Azure Table Storage port as 127.0.0.1:10002, followed by the emulated storage account name:

Method Request URI HTTP version
POST http://127.0.0.1:10002/devstoreaccount1/Tables HTTP/1.1

The Table service in the storage emulator differs from the Table Storage service in several ways. For more information, see Differences between the storage emulator and Azure Storage services.

URI parameters

None.

Request headers

The required and optional request headers are described in the following table:

Request header Description
Authorization Required. Specifies the authorization scheme, account name, and signature. For more information, see Authorize requests to Azure Storage.
Date or x-ms-date Required. Specifies the Coordinated Universal Time (UTC) for the request. For more information, see Authorize requests to Azure Storage.
x-ms-version Optional. Specifies the version of the operation to use for this request. For more information, see Versioning for the Azure Storage services.
Content-Type Required. Specifies the content type of the payload. Possible values are:

- application/atom+xml (versions earlier than 2015-12-11 only)
- application/json

For more information, see Payload format for Table Storage operations.
Accept Optional. Specifies the accepted content type of the response payload. Possible values are:

- application/atom+xml (versions earlier than 2015-12-11 only)
- application/json;odata=nometadata
- application/json;odata=minimalmetadata
- application/json;odata=fullmetadata

For more information, see Payload Format for Table Service Operations.
Prefer Optional. Specifies whether the response should include the inserted entity in the payload. Possible values are return-no-content and return-content.

For more information about this header, see Set the Prefer header to manage response echo on insert operations.
Content-Length Required. The length of the request body.
x-ms-client-request-id Optional. Provides a client-generated, opaque value with a 1-kibibyte (KiB) character limit that's recorded in the logs when logging is configured. We highly recommend that you use this header to correlate client-side activities with requests that the server receives. For more information, see Monitor Azure Table Storage.

Request body

The request body specifies the name of the table to be created. Table names must conform to the naming restrictions that are described in Understand the Table Storage data model.

The request body is an OData entity set, which can be expressed as JSON or as an Atom feed.

Note

JSON is the recommended payload format, and it's the only format that's supported for version 2015-12-11 and later.

For guidance on valid table names, see the "Table Names" section in Understand the Table Storage data model.

JSON (version 2013-08-15 and later)

The request body as a JSON feed is in the following general format:

{   
    "TableName":"mytable"  
}

Atom feed (versions earlier than 2015-12-11)

The request body as an Atom feed is in the following general format:

<?xml version="1.0" encoding="utf-8" standalone="yes"?>

          <d:TableName>mytable</d:TableName>  
        </m:properties>  
      </content>   
    </entry>

Response

The response includes an HTTP status code, a set of response headers, and a response body.

Status code

The status code depends on the value of the Prefer header. If the Prefer header is set to return-no-content, a successful operation returns status code 204 (No Content). If the Prefer header isn't specified or if it's set to return-content, a successful operation returns status code 201 (Created). For more information, see Set the Prefer header to manage response echo on insert operations.

For information about status codes, see Status and error codes and Table Storage error codes.

Response headers

The response for this operation includes the headers that are described in the following table. The response might also include additional standard HTTP headers. All standard headers conform to the HTTP/1.1 protocol specification.

Response header Description
x-ms-request-id Uniquely identifies the request that was made, and you can use it to troubleshoot the request. For more information, see Troubleshoot API operations.
x-ms-version Indicates the Table Storage version that was used to execute the request. This header is returned for requests that are made against version 2009-09-19 and later.
Date A UTC date/time value that's generated by the service, which indicates the time when the response was initiated.
Preference-Applied Indicates whether the Prefer request header was honored. If the response doesn't include this header, the Prefer header wasn't honored. If the header is returned, its value will be either return-content or return-no-content.

For more information, see Set the Prefer header to manage response echo on insert operations.
Content-Type Indicates the content type of the payload. The value depends on the value that's specified for the Accept request header. Possible values are:

- application/atom+xml
- application/json;odata=nometadata
- application/json;odata=minimalmetadata
- application/json;odata=fullmetadata

For more information about content types, see Payload format for Table Storage operations.
x-ms-client-request-id Can be used to troubleshoot requests and corresponding responses. The value of this header is equal to the value of the x-ms-client-request-id header if it's present in the request and the value contains no more than 1,024 visible ASCII characters. If the x-ms-client-request-id header isn't present, it isn't present in the response.

Response body

If the request includes the Prefer header with the value return-no-content, no response body is returned. Otherwise, the response body is an OData entity set.

Note

We recommend JSON as the payload format. It's the only format that's supported for version 2015-12-11 and later.
