Oracle offline synchronization

This article provides implementation ideas, configuration examples, and verification methods for Oracle offline synchronization scenarios, which can be used as a reference for actual project configuration.

Implement offline synchronization of data from the result table to the target table in Oracle (11g)

Case

Offline synchronization of data in t_source to t_target in Oracle

solution

CREATE TABLE from_table(
    username STRING,
    age INT
) WITH (
    'connector'='jdbc',
    'url'='jdbc:oracle:thin:@localhost:15201:helowin',
    'driver'='oracle.jdbc.driver.OracleDriver',
    'table-name'='T_SOURCE',
    'username'='root',
    'password'='root123',
    'scan.fetch-size'= '1'
);

CREATE TABLE target_table(
    username STRING,
    age INT
) WITH (
    'connector'='jdbc',
    'url'='jdbc:oracle:thin:@localhost:15201:helowin',
    'driver'='oracle.jdbc.driver.OracleDriver',
    'table-name'='T_SINK',
    'username'='root',
    'password'='root123',
    'sink.buffer-flush.max-rows'='1'); 

INSERT INTO target_table select * from from_table;
