deleteBySQL

Description

Deletes features in a table by performing a query on a table using an MI SQL Delete command string. In some cases the table will need a primary key column, depending on the data provider and the query. See the MapInfo SQL Language Reference for detailed information on MI SQL commands and functions.

ACL Authorization Flow

To delete features in a named table, the user (or the role they belong to) needs both EXECUTE and DELETE permission on the Named table.

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.
