创建一个KDB库，建立dblink，需要在KDB库内访问KINGBASE库中的数据；

KINGBASE=#CREATE DATABASE KDB

[kingbase@localhostconfig]$ vim sys_dblink.conf

[kingbase]DriverType=ODBCDriverName="KingbaseES7 ODBC Driver"Host=127.0.0.1Port=54321dbname=KINGBASE#dbname=REGRESSIONExtendedProperties="UseServerCursor=1;Fetch=1000"

CREATE TABLE tb1(col1 INT, col2 CHAR(10), col3TIMESTAMP);
CREATE TABLE tb2(col2 BIGINT, col3 VARCHAR(10), col4 BOOL);
INSERT INTO tb1 VALUES(100, 'char', current_timestamp);
INSERT INTO tb2 VALUES(100, 'varchar', 't');
KINGBASE=# SELECT * FROM tb1;

COL1 | COL2 | COL3

------+------------+----------------------------

100 | char | 2014-09-18 19:33:19.401817

(1 row)

KDB=# CREATE PUBLIC DATABASE LINK KINGBASE CONNECT TO'SYSTEM' IDENTIFIED BY 'beijing' USING 'kingbase';

KDB=# SELECT * FROM tb1@kingbase;

COL1 | COL2 | COL3

------+------------+----------------------------

100 | char | 2014-09-18 19:33:19.401817
