首先，我們知道php是完全支持oracle的，那么作為php框架的thinkphp5也是完全可以支持oracle的。
thinkphp5如何連接oracle？
數(shù)據(jù)庫：ray
表的結(jié)構(gòu)：ray_user
CREATE TABLE IF NOT EXISTS ray_user ( user_id int(11) unsigned NOT NULL AUTO_INCREMENT, user_name varchar(10) NOT NULL, user_pwd varchar(40) NOT NULL, PRIMARY KEY (user_id) ) ENGINE=InnoDB DEFAULT CHARSET=utf8 AUTO_INCREMENT=18 ;
轉(zhuǎn)存表中的數(shù)據(jù)：ray_user
INSERT INTO ray_user (user_id, user_name, user_pwd) VALUES (1, ‘updatename’, ‘ray’), (2, ‘testname’, ‘testpwd’),

控制器User.php
<?php namespace appindexcontroller; use thinkController; use appindexmodelUser as US; class User extends Controller { public function index() { $obj_user = new US; // 查找 $data = $obj_user->operateUser("find",null,"1"); var_dump($data); // 更新 $updateData = [ 'user_name' => 'updatename' ]; $result = $obj_user->operateUser("update",$updateData,"1"); var_dump($result); // 新增 $insertData = [ 'user_name' => 'testname', 'user_pwd' => 'testpwd' ]; $result = $obj_user->operateUser("insert",$insertData); var_dump($result); // 刪除 $result = $obj_user->operateUser("delete",null,'2'); var_dump($result); } }
模型User.php
<?php namespace appindexmodel; use thinkModel; class User extends Model { public function operateUser($directive,$data = null,$user_id = null) { if($directive == "find" && $user_id != null) { return User::where('user_id',$user_id)->find(); } else if($directive == "insert" && $data != null) { return User::save($data) ? 1 : 0; } else if($directive == "update" && $data != null && $user_id != null) { return User::where('user_id',$user_id)->find()->save($data) ? 1 : 0; } else if($directive == "delete" && $user_id != null) { return User::where('user_id',$user_id)->delete() ? 1 : 0; } else { return null; } } }
2、oracle環(huán)境下的CURD操作
數(shù)據(jù)庫配置文件database.php
<?php // +---------------------------------------------------------------------- // | ThinkPHP [ WE CAN DO IT JUST THINK ] // +---------------------------------------------------------------------- // | Copyright (c) 2006~2018 http://thinkphp.cn All rights reserved. // +---------------------------------------------------------------------- // | Licensed ( http://www.apache.org/licenses/LICENSE-2.0 ) // +---------------------------------------------------------------------- // | Author: liu21st <liu21st@gmail.com> // +---------------------------------------------------------------------- return [ // 數(shù)據(jù)庫類型 'type' => 'thinkoracleConnection', // 服務(wù)器地址 'hostname' => '127.0.0.1', // 數(shù)據(jù)庫名 'database' => 'orcl', // 用戶名 'username' => 'Scott', // 密碼 'password' => '', // 你的密碼 // 端口 'hostport' => '1521', // 連接dsn 'dsn' => '', // 數(shù)據(jù)庫連接參數(shù) 'params' => [], // 數(shù)據(jù)庫編碼默認(rèn)采用utf8 'charset' => 'utf8', // 數(shù)據(jù)庫表前綴 'prefix' => 'ray_', // 數(shù)據(jù)庫調(diào)試模式 'debug' => true, // 數(shù)據(jù)庫部署方式:0 集中式(單一服務(wù)器),1 分布式(主從服務(wù)器) 'deploy' => 0, // 數(shù)據(jù)庫讀寫是否分離 主從式有效 'rw_separate' => false, // 讀寫分離后 主服務(wù)器數(shù)量 'master_num' => 1, // 指定從服務(wù)器序號(hào) 'slave_no' => '', // 是否嚴(yán)格檢查字段是否存在 'fields_strict' => true, // 數(shù)據(jù)集返回類型 'resultset_type' => 'array', // 自動(dòng)寫入時(shí)間戳字段 'auto_timestamp' => false, // 時(shí)間字段取出后的默認(rèn)時(shí)間格式 'datetime_format' => 'Y-m-d H:i:s', // 是否需要進(jìn)行SQL性能分析 'sql_explain' => false, ];
3、根據(jù)指定ID查詢記錄
由于Oracle表名和字段名均需加上雙引號(hào)，故改寫thinkphplibrarydbBuilder.php中的parseSqlTable和parseWhereItem方法。改寫完成后根據(jù)ID查詢記錄OK。
... /** * 將SQL語句中的__TABLE_NAME__字符串替換成帶前綴的表名（小寫） * @access protected * @param string $sql sql語句 * @return string */ protected function parseSqlTable($sql) { return '"'. strtoupper($this->query->parseSqlTable($sql)).'"'; //// 前后加上雙引號(hào)并將表明設(shè)置為大寫 } ...... // where子單元分析 protected function parseWhereItem($field, $val, $rule = '', $options = [], $binds = [], $bindName = null) { // 字段分析 $key = $field ? '"'. $this->parseKey($field, $options, true) .'"' : ''; ////前后加上雙引號(hào) // 查詢規(guī)則和條件 if (!is_array($val)) { $val = is_null($val) ? ['null', ''] : ['=', $val]; } list($exp, $value) = $val; ...
改寫了控制器和模型層方法：
控制器Users.php
<?php namespace appindexcontroller; use thinkController; use appindexmodelUsers as US; class Users extends Controller { public function index() { // 查詢 $obj_users = new US; $data = $obj_users->operateUser("find",null,"1"); var_dump($data); // 更新 $updateData = [ 'NAME' => "updateora", 'PWD' => "newpwd" ]; $result = $obj_users->operateUser("update",$updateData,"1"); var_dump($result); // 插入 $insertData = [ 'NAME' => 'testname', 'PWD' => 'testpwd' ]; $result = $obj_users->operateUser("insert",$insertData); var_dump($result); // 刪除 $result = $obj_users->operateUser("delete",null,'18'); var_dump($result); } }
模型Users.php
<?php namespace appindexmodel; use thinkModel; class Users extends Model { public function operateUser($directive,$data = null,$ID = null) { if($directive == "find" && $ID != null) { return Users::where('ID',$ID)->find(); } else if($directive == "insert" && $data != null) { /*$id = Users::getLastInsID('SEQUSERS')-2; var_dump($id); $data['ID'] = $id;*/ return Users::save($data,[],'SEQUSERS') ? 1 : 0; // 注意這里傳參 } else if($directive == "update" && $data != null && $ID != null) { return Users::where('ID',$ID)->find()->save($data) ? 1 : 0; } else if($directive == "delete" && $ID != null) { return Users::where('ID',$ID)->delete() ? 1 : 0; } else { return null; } } }
經(jīng)測(cè)試更新數(shù)據(jù)通過，接下來是最為頭疼的新增。因?yàn)镸ySQL主鍵自增通過給PK添加A-I屬性即可，而Oracle則需要通過觸發(fā)器來實(shí)現(xiàn)。下面采用了簡(jiǎn)單的實(shí)現(xiàn)方法。
觸發(fā)器，序列實(shí)現(xiàn)Oracle主鍵自增。
CREATE OR REPLACE TRIGGER TRIUSERS BEFORE INSERT ON SCOTT.USERS FOR EACH ROW WHEN ( new.id is null ) begin select SEQUSERS.nextval into:new.id from dual; end; create sequence SEQUSERS minvalue 1 maxvalue 999999999999999999999999999 start with 1 increment by 1 nocache;
需要改寫think-oraclesrcConnection.php里面的getLastInsId()方法
/** * 獲取最近插入的ID * @access public * @param string $sequence 自增序列名 * @return string */ public function getLastInsID($sequence = null) { $pdo = $this->linkID->query("select {$sequence}.nextval as id from dual"); $pdo = $this->linkID->query("select {$sequence}.currval as id from dual"); $result = $pdo->fetchColumn(); $pdo = $this->linkID->query("alter sequence {$sequence} increment by -1"); $pdo = $this->linkID->query("select {$sequence}.nextval as id from dual"); $pdo = $this->linkID->query("alter sequence {$sequence} increment by 1"); return $result; }
