说明

cubrid_set_db_parameter ( resource $conn_identifier , int $param_type , int $param_value ) : bool

• PARAM_ISOLATION_LEVEL
• PARAM_LOCK_TIMEOUT

Note:

The auto-commit mode can be set by using cubrid_set_autocommit().

参数

conn_identifier

The CUBRID connection. If the connection identifier is not specified, the last link opened by cubrid_connect() is assumed.

param_type

Database parameter type.

param_value

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

false on failure.

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($conn, CUBRID_AUTOCOMMIT_TRUE);cubrid_set_db_parameter($conn, CUBRID_PARAM_ISOLATION_LEVEL, 2);$params_new = cubrid_get_db_parameter($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)
}
