I have requirement to pull a bunch of SQL's from a table in DB and execute them in parallel and update the status of each query as and when they complete. Can you please help me with ideas on how this can be achieved?
id - auto-generated number
full_sql - will have the sql to be executed
status - P : Pending (when the sql is added but not picked up for execution yet)
A : Active (Once the query is picked up for execution and is running)
C : Completed (Once the query execution has completed)
It will be easy to do this sequentially but the requirement is to run the sql's in parallel and at a time there will be no more than 10 sql;s in the table.

PDO.QUERY(3) 1 PDO.QUERY(3)PDO ::query - Executes an SQL statement, returning a result set as a PDOStatement object
SYNOPSIS
public PDOStatement PDO::query (string $statement)
DESCRIPTION
PDOStatement PDO::query (string $statement, int $PDO::FETCH_COLUMN, int $colno) PDOStatement PDO::query (string $statement, int
$PDO::FETCH_CLASS, string $classname, array $ctorargs) PDOStatement PDO::query (string $statement, int $PDO::FETCH_INTO, object
$object)
PDO.query(3) executes an SQL statement in a single function call, returning the result set (if any) returned by the statement as a
PDOStatement object.
For a query that you need to issue multiple times, you will realize better performance if you prepare a PDOStatement object using PDO.pre-
pare(3) and issue the statement with multiple calls to PDOStatement.execute(3).
If you do not fetch all of the data in a result set before issuing your next call to PDO.query(3), your call may fail. Call PDOState-
ment.closeCursor(3) to release the database resources associated with the PDOStatement object before issuing your next call to
PDO.query(3).
Note
Although this function is only documented as having a single parameter, you may pass additional arguments to this function. They
will be treated as though you called PDOStatement.setFetchMode(3) on the resultant statement object.
PARAMETERS
o $statement
- The SQL statement to prepare and execute. Data inside the query should be properly escaped.
RETURN VALUES PDO.query(3) returns a PDOStatement object, or FALSE on failure.
EXAMPLES
Example #1
Demonstrate PDO::query
A nice feature of PDO.query(3) is that it enables you to iterate over the rowset returned by a successfully executed SELECT state-
ment.
<?php
function getFruit($conn) {
$sql = 'SELECT name, color, calories FROM fruit ORDER BY name';
foreach ($conn->query($sql) as $row) {
print $row['name'] . " ";
print $row['color'] . " ";
print $row['calories'] . "
";
}
}
?>
The above example will output:
apple red 150
banana yellow 250
kiwi brown 75
lemon yellow 25
orange orange 300
pear green 150
watermelon pink 90
