首先我们要安装好sqoop 笔者我用的是sqoop1 其次我们需要ojdbc6.jar 这个jar 包下载地址如下: http://www.oracle.com/technetwork/database/enterprise-edition/jdbc-112010-090769.html 将解压的包 复制到sqoop安装目录下的lib 目录中 最后执行我们的导入

其次我们需要ojdbc6.jar 这个jar 包下载地址如下:
http://www.oracle.com/technetwork/database/enterprise-edition/jdbc-112010-090769.html
将解压的包 复制到sqoop安装目录下的lib 目录中
最后执行我们的导入命令即可
sqoop export --table FDC_JPLP --connect jdbc:oracle:thin:@localhost:port:test1 --username test --password test --export-dir /user/hive/warehouse/data_w.db/seq_fdc_jplp --columns goal_ocityid,goal_issueid,compete_issueid,ncompete_rank --input-fields-terminated-by '\001' --input-lines-terminated-by '\n'
注意要指定 --columns 参数 否则会报错 找不到 columns
用法: --columns
查询数据是否导入成功
sqoop eval --connect jdbc:oracle:thin:@localhost:port:test1 --query "select * from FDC_JPLP" --username fccsreport --password fccsoracle10g_report
当然你也可以使用Oracle相关的管理工具查看。
说明:做数据导入 导出操作的时候请注意 两边表字段类型尽量要保持一致 否则会出现数据类型转化错误

Adding MySQL users through the PHP web interface can use MySQLi extensions. The steps are as follows: 1. Connect to the MySQL database and use the MySQLi extension. 2. Create a user, use the CREATEUSER statement, and use the PASSWORD() function to encrypt the password. 3. Prevent SQL injection and use the mysqli_real_escape_string() function to process user input. 4. Assign permissions to new users and use the GRANT statement.
