In-Depth Information
There are now two additional criteria columns that relate to the
`book`.`title`
and
the
`book`.`genre`
columns respectively. phpMyAdmin used its knowledge of the
relations defined between the tables to generate a
LEFT
JOIN
clause (highlighted
in the preceding screenshot) on the
author_id
key column. A shortcoming of the
current version is that only the internal relations, and not the
InnoDB
relations,
are examined.
There may be more than two tables involved in a join.
Executing the query
Clicking on the
Submit
Query
button sends the query for execution. In the following
screenshot, you can see the complete generated query in the upper part, and the
resulting data row in the lower part:
There is no easy way (except by using the browser's
Back
button) to come back to the
query generation page once we have submitted the query.
Chapter
14
discusses how
to save the generated query for later execution.
