PDO_CUBRID is a driver that implements the PHP Data Objects (PDO) interface to enable access from PHP to CUBRID databases.


Current version of PDO_CUBRID doesn't support persistent connection now.


To build the PDO_CUBRID extension, the CUBRID DBMS must be installed on the same system as PHP. PDO_CUBRID is a » PECL extension, so follow the instructions in PECL 확장의 설치 to install the PDO_CUBRID extension. Issue the configure command to point to the location of your CUBRID base dir as follows:

   $ ./configure --with-pdo-cubrid=/path/to/CUBRID[,shared]
The configure command defaults to the value of the CUBRID environment variable.

PECL 확장에 대한 DLL은 현재 사용할 수 없습니다. 윈도우에서 빌드하기 섹션을 참고하십시오. Detailed information about installation on Linux and Windows manually, please read build-guide.html in PECL package CUBRID for reference.


Feature Description
Scrollable cursors PDO_CUBRID supports scrollable cursors. The default cursor type is forward only, and you can use parameter driver_options in PDO::prepare() to change cursor type.
Timeout PDO_CUBRID supports sql statement execution timeout setting; You can use PDO::setAttribute() to set timeout value.
Autocommit_mode and Transaction PDO_CUBRID supports both autocommit_mode and transaction, and autocommit_mode is enabled by default. You can use PDO::setAttribute() to change its state.

If you use PDO::beginTransaction() to begin a transaction, it will disable autocommit_mode automatically and restore it after PDO::commit() or PDO::rollBack(). Note that before disabling the autocommit_mode, any pending work is automatically committed.

Multiple SQL Statements PDO_CUBRID supports Multiple SQL statements. Multiple SQL statements are separated by semicolons (;)
Schema Information PDO_CUBRID implements a function PDO::cubrid_schema() to get schema information.
LOBs PDO_CUBRID supports BLOB/CLOB data type. The LOB in PDO is represented as a stream, so you can insert LOBs by binding a stream, and get LOBs by reading a stream returned by CUBRID PDO. For example:

Example #1 Insert LOBs in CUBRID PDO


$sql_stmt "INSERT INTO lob_test(name, content) VALUES('lob_test.png', ?)";

$stmt $dbh->prepare($sql_stmt);
$ret $stmt->bindParam(1$fpPDO::PARAM_LOB);
$ret $stmt->execute();

Example #2 Fetch LOBs in CUBRID PDO

"SELECT content FROM lob_test WHERE name='lob_test.png'";

$stmt $dbh->prepare($sql_stmt);
$result $stmt->fetch(PDO::FETCH_NUM);

header("Content-Type: image/png");

Column meta The PDOStatement::getColumnMeta() in CUBRID PDO will return an associative array containing the following values:
  • type
  • name
  • table
  • def
  • precision
  • scale
  • not_null
  • auto_increment
  • unique_key
  • multiple_key
  • primary_key
  • foreign_key
  • reverse_index
  • reverse_unique
Collection Data Type PDO_CUBRID supports SET/MULTISET/SEQUENCE data type. If you don't specify data type, the default data type is char,for example:

Example #3 Insert set in CUBRID PDO with default data type.

$cubrid_pdo = new PDO($conn_str'dba''');

$cubrid_pdo->exec("DROP TABLE if exists test_tbl"); 
$cubrid_pdo->exec("CREATE TABLE test_tbl (col_1 SET(VARCHAR))");
$sql_stmt_insert "INSERT INTO test_tbl VALUES (?);";
$stmt $cubrid_pdo->prepare($sql_stmt_insert);
$data = array("abc","def","ghi");
$ret $stmt->bindParam(1$dataPDO::PARAM_NULL);
$ret $stmt->execute();

Example #4 Specify data type when insert set in CUBRID PDO

$cubrid_pdo = new PDO($conn_str'dba''');

$cubrid_pdo->exec("DROP TABLE if exists test_tbl"); 
$cubrid_pdo->exec("CREATE TABLE test_tbl (col_1 SET(int))");
$sql_stmt_insert "INSERT INTO test_tbl VALUES (?);";
$stmt $cubrid_pdo->prepare($sql_stmt_insert);
$data = array(1,2,3,4);
$ret $stmt->bindParam(1$data0,0,"int");
$ret $stmt->execute();

CUBRID Bind Data Types:(The fifth parameter of PDOStatement::bindParam):
  • CHAR
  • BIT
  • INT
  • DATE
  • TIME

예약 상수

아래 상수는 이 드라이버에서 정의된 것으로, 확장을 PHP에 컴파일하였거나 실행중에 동적 로드하였을 때만 사용할 수 있습니다. 추가로, 드라이버-특정 상수는 이 드라이버를 사용할 때만 사용할 수 있습니다. mysql-특정 속성를 postgres 드라이버에서 사용하면 기대하지 않은 작동을 할 수 있습니다. 코드에서 여러 드라이버를 실행한다면, PDO::getAttribute()를 사용하여 PDO_ATTR_DRIVER_NAME 속성으로 드라이버를 확인할 수 있습니다.

The following constants can be used when setting the database attribute. They can be passed to PDO::getAttribute() or PDO::setAttribute().

PDO::CUBRID attribute flags
Constant Description
PDO::CUBRID_ATTR_ISOLATION_LEVEL Transaction isolation level for the database connection.
PDO::CUBRID_ATTR_LOCK_TIMEOUT Transaction timeout in seconds.
PDO::CUBRID_ATTR_MAX_STRING_LENGTH Read only. The maximum string length for bit, varbit, char, varchar, nchar, nchar varying data types when using CUBRID PDO API.

The following constants can be used when setting the transaction isolation level. They can be passed to PDO::getAttribute() or returned by PDO::setAttribute().

PDO::CUBRID isolation level flags
Constant Description
PDO::TRAN_COMMIT_CLASS_UNCOMMIT_INSTANCE The lowest isolation level (1). A dirty, non-repeatable or phantom read may occur for the tuple and a non-repeatable read may occur for the table as well.
PDO::TRAN_COMMIT_CLASS_COMMIT_INSTANCE A relatively low isolation level (2). A dirty read does not occur, but non-repeatable or phantom read may occur.
PDO::TRAN_REP_CLASS_UNCOMMIT_INSTANCE The default isolation of CUBRID (3). A dirty, non-repeatable or phantom read may occur for the tuple, but repeatable read is ensured for the table.
PDO::TRAN_REP_CLASS_COMMIT_INSTANCE A relatively low isolation level (4). A dirty read does not occur, but non-repeatable or phantom read may.
PDO::TRAN_REP_CLASS_REP_INSTANCE A relatively high isolation level (5). A dirty or non-repeatable read does not occur, but a phantom read may.
PDO::TRAN_SERIALIZABLE The highest isolation level (6). Problems concerning concurrency (e.g. dirty read, non-repeatable read, phantom read, etc.) do not occur.

The following constants can be used when getting schema information. They can be passed to PDO::cubrid_schema().

PDO::CUBRID schema flags
Constant Description
PDO::CUBRID_SCH_TABLE Get name and type of table in CUBRID.
PDO::CUBRID_SCH_VIEW Get name and type of view in CUBRID.
PDO::CUBRID_SCH_QUERY_SPEC Get the query definition of view.
PDO::CUBRID_SCH_ATTRIBUTE Get the attributes of table column.
PDO::CUBRID_SCH_TABLE_ATTRIBUTE Get the attributes of table.
PDO::CUBRID_SCH_METHOD Get the instance method. The instance method is a method called by a class instance. It is used more often than the class method because most operations are executed in the instance.
PDO::CUBRID_SCH_TABLE_METHOD Get the class method. The class method is a method called by a class object. It is usually used to create a new class instance or to initialize it. It is also used to access or update class attributes.
PDO::CUBRID_SCH_METHOD_FILE Get the information of the file where the method of the table is defined.
PDO::CUBRID_SCH_SUPER_TABLE Get the name and type of table which table inherites attributes from.
PDO::CUBRID_SCH_SUB_TABLE Get the name and type of table which inherites attributes from this table.
PDO::CUBRID_SCH_CONSTRAINT Get the table constraints.
PDO::CUBRID_SCH_TRIGGER Get the table triggers.
PDO::CUBRID_SCH_TABLE_PRIVILEGE Get the privilege information of table.
PDO::CUBRID_SCH_COL_PRIVILEGE Get the privilege information of column.
PDO::CUBRID_SCH_DIRECT_SUPER_TABLE Get the direct super table of table.
PDO::CUBRID_SCH_PRIMARY_KEY Get the table primary key.
PDO::CUBRID_SCH_IMPORTED_KEYS Get imported keys of table.
PDO::CUBRID_SCH_EXPORTED_KEYS Get exported keys of table.
PDO::CUBRID_SCH_CROSS_REFERENCE Get reference relationship of tow tables.
