MYSQLND_MS_QUERY_IS_SELECT(3) 1 MYSQLND_MS_QUERY_IS_SELECT(3)mysqlnd_ms_query_is_select - Find whether to send the query to the master, the slave or the last used MySQL serverSYNOPSIS
int mysqlnd_ms_query_is_select (string $query)
DESCRIPTION
Finds whether to send the query to the master, the slave or the last used MySQL server.
The plugins built-in read/write split mechanism will be used to analyze the query string to make a recommendation where to send the query.
The built-in read/write split mechanism is very basic and simple. The plugin will recommend sending all queries to the MySQL replication
master server but those which begin with SELECT, or begin with a SQL hint which enforces sending the query to a slave server. Due to the
basic but fast algorithm the plugin may propose to run some read-only statements such as SHOW TABLES on the replication master.
PARAMETERS
o $query
- Query string to test.
RETURN VALUES
A return value of MYSQLND_MS_QUERY_USE_MASTER indicates that the query should be send to the MySQL replication master server. The function
returns a value of MYSQLND_MS_QUERY_USE_SLAVE if the query can be run on a slave because it is considered read-only. A value of
MYSQLND_MS_QUERY_USE_LAST_USED is returned to recommend running the query on the last used server. This can either be a MySQL replication
master server or a MySQL replication slave server.
If read write splitting has been disabled by setting mysqlnd_ms.disable_rw_split, the function will always return
MYSQLND_MS_QUERY_USE_MASTER or MYSQLND_MS_QUERY_USE_LAST_USED.
EXAMPLES
Example #1
mysqlnd_ms_query_is_select(3) example
<?php
function is_select($query)
{
switch (mysqlnd_ms_query_is_select($query))
{
case MYSQLND_MS_QUERY_USE_MASTER:
printf("'%s' should be run on the master.
", $query);
break;
case MYSQLND_MS_QUERY_USE_SLAVE:
printf("'%s' should be run on a slave.
", $query);
break;
case MYSQLND_MS_QUERY_USE_LAST_USED:
printf("'%s' should be run on the server that has run the previous query
", $query);
break;
default:
printf("No suggestion where to run the '%s', fallback to master recommended
", $query);
break;
}
}
is_select("INSERT INTO test(id) VALUES (1)");
is_select("SELECT 1 FROM DUAL");
is_select("/*" . MYSQLND_MS_LAST_USED_SWITCH . "*/SELECT 2 FROM DUAL");
?>
The above example will output:
INSERT INTO test(id) VALUES (1) should be run on the master.
SELECT 1 FROM DUAL should be run on a slave.
/*ms=last_used*/SELECT 2 FROM DUAL should be run on the server that has run the previous query
