sql query
fyi... Section 6.4.1 of the manual says:
"
SELECT [STRAIGHT_JOIN]
[SQL_SMALL_RESULT] [SQL_BIG_RESULT] [SQL_BUFFER_RESULT]
[SQL_CACHE | SQL_NO_CACHE] [SQL_CALC_FOUND_ROWS] [HIGH_PRIORITY]
[DISTINCT | DISTINCTROW | ALL]
select_expression,...
[INTO {OUTFILE | DUMPFILE} 'file_name' export_options]
[FROM table_references
[WHERE where_definition]
[GROUP BY {unsigned_integer | col_name | formula} [ASC | DESC], ...]
[HAVING where_definition]
[ORDER BY {unsigned_integer | col_name | formula} [ASC | DESC] ,...]
[LIMIT [offset,] rows]
[PROCEDURE procedure_name]
[FOR UPDATE | LOCK IN SHARE MODE]]
"
In addition to being able to specify an update lock or a shared mode
lock, one should be able to specify no lock. This is the moral
equivalent of the Sybase "noholdlock" option. This is useful if you
normally want to run in a high isolation environment but are, say,
running a transaction where you don't need repeatable reads for some
select in that transaction.
