DELETE

The DELETE statement deletes table rows specified in the statement's WHERE clause. If the optional WHERE clause is not specified, then the DELETE statement deletes all rows of the table.

When deleting row(s) of a multi-tenant table, a regular tenant can only delete rows in its partition, but a super-tenant or a DBA can delete rows in all the tenant partitions and group partitions. A super-tenant or a DBA may refine which tenants' rows must be affected by using the tenantid_tbl() or the tenantName_tbl() function in the WHERE clause search_condition.

The DELETE statement uses the following syntax:

Syntax

DELETE FROM [owner_name]{table_name|view_name}[ WHERE search_condition] ;

The following example depicts a simple delete on a single table.

DELETE from Customer
     WHERE Name = 'Hoops' ;

The following example deletes the row from a multi-tenant table using custnum and tenantid_tbl() in the WHERE clause.

DELETE FROM mtcustomer
WHERE custnum = 1428 AND tenantName_tbl (pub.mtcustomer) = 'SNCSoftware';
