SQL Server 2019 : PHP から利用する2020/04/23

 
PHP からの SQL Server 利用例です。
[1] PHP 7.2 インストール済みを前提として例示します。
追加で必要なパッケージをインストールしておきます。
[root@dlp ~]#
dnf -y install gcc make php-pear php-pdo php-devel

[root@dlp ~]#
pecl install sqlsrv pdo_sqlsrv

[root@dlp ~]#
echo 'extension=pdo_sqlsrv.so' > /etc/php.d/30-pdo_sqlsrv.ini

[root@dlp ~]#
echo 'extension=sqlsrv.so' > /etc/php.d/30-sqlsrv.ini

[2] テスト用のデータベース接続用ユーザーとデータベースを作成しておきます。
[cent@dlp ~]$
sqlcmd -S localhost -U SA

Password:
# ログインユーザー作成
1> create login cent with PASSWORD= N'password';
2> go

# [SampleDB] 作成
1> create database SampleDB;
2> go

1> use SampleDB;
2> go
Changed database context to 'SampleDB'.

# ログインユーザー [cent] と関連付けて DBユーザー作成
1> create user cent for login cent;
2> go

# [cent] にDBオーナーロール付与
1> exec sp_addrolemember 'db_owner', 'cent';
2> go

# テストテーブル作成
1> create table SampleTable (
2> ID int identity(1,1) not null primary key, First_Name NVARCHAR(50), Last_Name NVARCHAR(50)
3> );
4> insert into SampleTable (
5> First_Name, Last_Name) values (N'CentOS', N'Linux'), (N'RedHat', N'Linux'), (N'Fedora', N'Linux'
6> );
7> go
[3] 基本的な利用例です。データベースや接続ユーザーは上記で作成したものを使用します。
