PXF访问SQL Server

本示例演示如何使用PXF连接SQLServer2016

1. PXF安装

sudo yum install pxf-matrixdb3-5.16.1-1.el7.x86_64.rpm -y
sudo mkdir /usr/local/pxfconf
sudo chown mxadmin.mxadmin -R /usr/local/pxfconf
sudo chown mxadmin.mxadmin -R /usr/local/pxf-matrixdb3

export PXF_HOME=/usr/local/pxf-matrixdb3
export PXF_CONF=/usr/local/pxfconf
export PATH=$PXF_HOME/bin:$PATH

cd $PXF_CONF/servers
mkdir sqlserv_server

2. 配置

初始化PXF:

pxf cluster init

https://docs.microsoft.com/en-us/sql/connect/jdbc/using-the-jdbc-driver?view=sql-server-ver15 下载jdbc驱动: sqljdbc4.jar 将驱动放入pxf库目录(所有节点都需要):

cp sqljdbc4.jar $PXF_CONF/lib

同步配置到其它节点:

pxf cluster sync

3. 启动并查看集群状态

启动节点:

pxf cluster start

查看集群状态:

pxf cluster status

4. 访问

创建插件:

postgres=# create extension pxf_fdw ;
CREATE EXTENSION

定义SERVER:

DROP SERVER sqlserv_server cascade;

CREATE SERVER sqlserv_server FOREIGN DATA WRAPPER jdbc_pxf_fdw OPTIONS (
    jdbc_driver 'com.microsoft.sqlserver.jdbc.SQLServerDriver',
    db_url 'jdbc:sqlserver://{ip}:{端口};databaseName={数据库名}',
    batch_size '10000',
    fetch_size '2000'
);

创建用户映射:

CREATE USER MAPPING FOR mxadmin SERVER sqlserv_server OPTIONS ( user '{用户名}' , pass '{密码}');

创建外部表:

CREATE FOREIGN TABLE foreign_sqlserver (
    id int4  ,
    banzu varchar(20) ,
    banzu_name varchar(50) ,
    realdate timestamp
)
SERVER sqlserv_server
OPTIONS (resource '{源数据库schema.表名}');

通过外部表访问SQL Server数据:

select * from foreign_sqlserver limit 10;
