php Detailed explanation of accessing oracle stored procedure instances
For example, my local Oracle database has a package with a stored procedure in it:
create or replace package PKG_TRANS_REL is -- Author : test -- Created : -- Purpose : test -- Public type declarations PKG_NAME varchar2(20) := 'PKG_TRANS_REL'; --存储过程,测试用 procedure pro_GC_withdraw(in_merch_no in varchar2, in_withdraw_amt in number, out_result out number, out_errmsg out varchar2); end PKG_TRANS_REL;
The package name is PKG_TRANS_REL, and the stored procedure is pro_GC_withdraw. This stored procedure has four parameters, two input parameters and two output parameters.
Example of calling via pdo in PHP:
$this->_pdo = new PDO(PDO_DB_DNS, PDO_DB_USER, PDO_DB_PASSWORD); $call = "CALL PKG_TRANS_REL.pro_GC_withdraw(?,?,?,?)"; try{ $stmt = $this->_pdo->prepare($call); $stmt->bindParam(1, $merch_no); $stmt->bindParam(2, $amount, PDO::PARAM_INT); $stmt->bindParam(3, $result, PDO::PARAM_INT, 4); $stmt->bindParam(4, $error_msg, PDO::PARAM_STR, 64); $stmt->execute(); }catch (PDOException $e) { $msg = 'SQL:'.$e->getMessage(); $msg = iconv('GBK','UTF-8',$msg); user_dump('SQL:'.$msg); return false; } ...
The third parameter of bindParam defaults to PDO::PARAM_STR, if it is other types To specify
It is relatively simple to pass the value of the incoming parameter, but it is slightly more complicated to pass the outgoing parameter, and the length must be specified.
