param_value

Isolation level value (1-6) or lock timeout (in seconds) value.

范例

Example #1 cubrid_get_db_parameter() example

<?php
$conn 
cubrid_connect("localhost"33000"demodb""dba");

$params cubrid_get_db_parameter($conn);
var_dump($params);

cubrid_set_autocommit($connCUBRID_AUTOCOMMIT_TRUE);
cubrid_set_db_parameter($connCUBRID_PARAM_ISOLATION_LEVEL2);

$params_new cubrid_get_db_parameter($conn);
var_dump($params_new);

cubrid_disconnect($conn);
?>

以上例程会输出:

array(4) {
  ["PARAM_ISOLATION_LEVEL"]=>
  int(3)
  ["PARAM_LOCK_TIMEOUT"]=>
  int(-1)
  ["PARAM_MAX_STRING_LENGTH"]=>
  int(1073741823)
  ["PARAM_AUTO_COMMIT"]=>
  int(0)
}
array(4) {
  ["PARAM_ISOLATION_LEVEL"]=>
  int(2)
  ["PARAM_LOCK_TIMEOUT"]=>
  int(-1)
  ["PARAM_MAX_STRING_LENGTH"]=>
  int(1073741823)
  ["PARAM_AUTO_COMMIT"]=>
  int(1)
}
