SELECT tableA.columnA, tableA.columnB, tableB.columnX, tableB.columnY FROM tableA, tableB WHERE tableA.columnA = tableB.columnX AND tableA.columnB = tableB.columnY;In the same above, the rows from the two tables are joined where ColumnA = ColumnX and ColumnB = ColumnY. You can code any join condition this way. Oracle also supports the ANSI SQL standard join syntax. The above query in ANSI SQL standard would look like the following:
SELECT tableA.columnA, tableA.columnB, tableB.columnX, tableB.columnY FROM tableA INNER JOIN tableB ON tableA.columnA = tableB.columnX AND tableA.columnB = tableB.columnY;
