For information on defining a load isolated table, see the WITH ISOLATED LOADING option for CREATE TABLE and ALTER TABLE in Teradata Vantage™ - SQL Data Definition Language Syntax and Examples, B035-1144.
CREATE TABLE ldi_table1, WITH CONCURRENT ISOLATED LOADING FOR ALL (a INTEGER, b INTEGER, c INTEGER) PRIMARY INDEX ( a );
UPDATE WITH CONCURRENT ISOLATED LOADING ldi_table1 SET b = b + 1;
An EXPLAIN shows that the UPDATE step is performed as concurrent load isolated. The isolated load begins and performs a concurrent load isolated UPDATE of ldi_table1 (Load Uncommitted) with a condition of ("(ldi_table1.TD_ROWLOADID_DEL = 0) AND ((1=1))").
