$conn_identifier, int $param_type, int $param_value): boolThe cubrid_set_db_parameter() function is used to set the CUBRID database parameters. It can set the following CUBRID database parameters:
PARAM_ISOLATION_LEVELPARAM_LOCK_TIMEOUT
注意:
The auto-commit mode can be set by using cubrid_set_autocommit().
參數
-
conn_identifier -
The CUBRID connection. If the connection identifier is not specified, the last link opened by cubrid_connect() is assumed.

範例
示例 #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);
?>
以上例程會輸出：
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)
}
