DB2: What is Atomic in SQL Query

Inserting of multiple rows into Table is possible in DB2 and the below is the SQL to use in DB2.

EXEC SQL INSERT INTO test-table (col1, col2, col3) 

In this example, the INSERT into table column is the same as any other INSERT statement you might have used in previous versions of DB2. Even the VALUES clause looks the same.

However, in our example, the host variables used in the VALUES clause are all defined as arrays in our COBOL program.

Adding FOR 50 ROWS tells DB2 that the arrays will contain 50 values.

And finally, the keyword ATOMIC tells DB2 to treat the entire INSERT as a single piece of work were all rows will be inserted or no rows will be inserted.
