These rows are sometimes called childless parent rows. More or less, the use case for this type of query is to find order headers without order lines. Add the following line 8 to the query and you get only those rows in the righthand table that have no parent-related rows in the lefthand table.

These rows are sometimes called orphans because they have no parent row. More or less, the use case for this type of query is to find latent order lines after deleting the order header. Add the following lines 18 and 19 to the query and you get only those rows that are childless parent rows or orphaned child rows. More or less, the use case for this type of query is to find both order headers without order lines and order lines abandoned by deleted order headers.

With respect to determining which rows satisfy the join condition, both joins are semantically identical. That column is omitted from the result.

An ON clause can refer only to its operands. The statement fails with an Unknown column 'i3' in 'on clause' error because i3 is a column in t3 , which is not an operand of the ON clause. To enable the join to be processed, rewrite the statement as follows:. This affects statements that use an ON clause because that clause can refer only to columns in the operands of the join, and the precedence affects interpretation of what those operands are. Because t1. Group the first two tables explicitly with parentheses so that the operands for the ON clause are t1, t2 and t3 :.
