Delete Features Using SQL

Description

Deletes features in a table by performing a query on a table using an MI SQL Delete command string. See the MapInfo SQL Language Reference for detailed information on MapInfo SQL functions.

Note: You must have View permissions on the named table as well as Create/Modify/Delete permissions on the named table's associated dataset to perform insert, update, and delete operations on writable tables. See Users and Roles in the Administration section for more information.

Note: Delete is supported on PostGIS, Oracle, SQL Server, GeoPackage, and generic JDBC tables. It also supported on MapInfo native TAB and extended native TAB (NativeX) files. Named tables with composite primary keys are not writable.

ACL Authorization Flow

To delete features in a named table by performing a query on a named table using an MI SQL delete command string, the user (or the role they belong to) needs both EXECUTE and DELETE permission on the Named table.

HTTP POST URL Format

The following format is used for HTTP POST requests:

HTTP POST:  /FeatureService/tables/features.rep?
POST Data: [delete=MI SQL query]
POST BODY: Content-Type:application/json {bound parameters}

Parameters

The {bound parameters} is a POST json body (Content-Type: application/json) for the MI SQL delete query containing one or multiple parameters to be included. Null values are supported; however, a type is still required.

Note: The json in the POST is optional; it is only required if the SQL query uses bound parameters.

For information on the parameter types listed below, see Request URL Data Types.

delete=DELETE FROM "/Samples/NamedTables/MyTable" WHERE Column1=@stringParam
{
                "parameters" : [
              {
