mysql can
read a query from its argument list. Use the -e
(or
--execute
) option to specify a query on the
command line.
For example, to find out how many records are in the
limbs
table, run this command:
% mysql -e "SELECT COUNT(*) FROM limbs" cookbook
+----------+
| COUNT(*) |
+----------+
| 12 |
+----------+
To run multiple queries with the -e
option, separate
them with semicolons:
% mysql -e "SELECT COUNT(*) FROM limbs;SELECT NOW( )" cookbook
+----------+
| COUNT(*) |
+----------+
| 12 |
+----------+
+---------------------+
| NOW( ) |
+---------------------+

By default, results generated by queries that are specified with
-e
are displayed in tabular format if output goes to
the terminal, and in tab-delimited format otherwise. To produce a
different output style, see Recipe 1.22.
