Example: Merging into a Table with an Implicit Isolated Load Operation - Analytics Database - Teradata Vantage

Following are the table definitions for the example:

CREATE TABLE ldi_table1,
     WITH CONCURRENT ISOLATED LOADING FOR ALL
     (a INTEGER,
      b INTEGER,
      c INTEGER)
PRIMARY INDEX ( a );


CREATE TABLE t1
     (c1 INTEGER,
      c2 INTEGER,
      c3 INTEGER)
PRIMARY INDEX ( c1 );

This statement performs a merge into the load isolated table ldi_table1 from table t1 as an implicit concurrent load isolated operation:

MERGE WITH ISOLATED LOADING INTO ldi_table1
    USING t1 ON a=c1
    WHEN NOT MATCHED THEN INSERT
    VALUES (c1, c2, c3);
