Question

我在Postgres中有一个表，我需要在MySQL中反映出来。我发现这个http://wiki.postgresql.org/wiki/Foreign_data_wrapper#mysql_fdw虽然方向很清楚如何实际链接到MySQL。 CREATE FOREIGN TABLE在Postgres中工作，但在MySQL中是一个语法错误。在运行所有CREATE FOREIGN TABLE并在Postgres中创建CREATE SERVER mysql_svr后，MySQL中没有任何数据神奇地出现，所以我必须错过一个步骤，他们不提供。

mysql> CREATE FOREIGN TABLE ex_staff ( id integer, name text, address text) SERVER mysql_svr OPTIONS (query ‘SELECT * FROM hr.employees WHERE date_left IS NOT NULL’);
ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'FOREIGN TABLE ex_staff ( id integer, name text, address text) SERVER mysql_svr O' at line 1

... DOH

OPTIONS (
    database 'myplace',
    schema 'test', 
    table 'dblist', 
    sql_query 'select description,id,name,created_datetime,sd,users from `test`.`dblist`',
    sql_count 'select count(id) from `test`.`dblist`',
    db_id 'id', 
    db_name 'name',
    db_desc 'description',
    db_users 'users',
    db_createdtime 'created_datetime'
);

使用mysql_fdw或者将表从Postgres连接到MySQL
