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(kù)：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(kù)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(kù)類型    'type'            => 'thinkoracleConnection',    // 服務(wù)器地址    'hostname'        => '127.0.0.1',    // 數(shù)據(jù)庫(kù)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(kù)連接參數(shù)    'params'          => [],    // 數(shù)據(jù)庫(kù)編碼默認(rèn)采用utf8    'charset'         => 'utf8',    // 數(shù)據(jù)庫(kù)表前綴    'prefix'          => 'ray_',    // 數(shù)據(jù)庫(kù)調(diào)試模式    'debug'           => true,    // 數(shù)據(jù)庫(kù)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(kù)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(yǔ)句中的__TABLE_NAME__字符串替換成帶前綴的表名（小寫）     * @access protected     * @param string $sql sql語(yǔ)句     * @return string     */    protected function parseSqlTable($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(guò)，接下來(lái)是最為頭疼的新增。因?yàn)镸ySQL主鍵自增通過(guò)給PK添加A-I屬性即可，而Oracle則需要通過(guò)觸發(fā)器來(lái)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;     }

以上內(nèi)容僅供參考！
