| # 导入导出 TsFile |
| |
| TsFile 工具可帮您 通过执行指定sql、命令行sql、sql文件的方式将结果集以TsFile文件的格式导出至指定路径. |
| |
| ## 使用 export-tsfile.sh |
| |
| ### 运行方法 |
| |
| ```shell |
| # Unix/OS X |
| > tools/export-tsfile.sh -h <ip> -p <port> -u <username> -pw <password> -td <directory> [-f <export filename> -q <query command> -s <sql file>] |
| |
| # Windows |
| > tools\export-tsfile.bat -h <ip> -p <port> -u <username> -pw <password> -td <directory> [-f <export filename> -q <query command> -s <sql file>] |
| ``` |
| |
| 参数: |
| * `-h <host>`: |
| - IoTDB服务的主机地址。 |
| * `-p <port>`: |
| - IoTDB服务的端口号。 |
| * `-u <username>`: |
| - IoTDB服务的用户名。 |
| * `-pw <password>`: |
| - IoTDB服务的密码。 |
| * `-td <directory>`: |
| - 为导出的TsFile文件指定输出路径。 |
| * `-f <tsfile name>`: |
| - 为导出的TsFile文件的文件名,只需写文件名称,不能包含文件路径和后缀。如果sql文件或控制台输入时包含多个sql,会按照sql顺序生成多个TsFile文件。 |
| - 例如:文件中或命令行共有3个SQL,-f 为"dump",那么会在目标路径下生成 dump0.tsfile、dump1.tsfile、dump2.tsfile三个TsFile文件。 |
| * `-q <query command>`: |
| - 在命令中直接指定想要执行的查询语句。 |
| - 例如: `select * from root.** limit 100` |
| * `-s <sql file>`: |
| - 指定一个SQL文件,里面包含一条或多条SQL语句。如果一个SQL文件中包含多条SQL语句,SQL语句之间应该用换行符进行分割。每一条SQL语句对应一个输出的TsFile文件。 |
| |
| |
| 除此之外,如果你没有使用`-s`和`-q`参数,在导出脚本被启动之后你需要按照程序提示输入查询语句,不同的查询结果会被保存到不同的TsFile文件中。 |
| |
| ### 运行示例 |
| |
| ```shell |
| # Unix/OS X |
| > tools/export-tsfile.sh -h 127.0.0.1 -p 6667 -u root -pw root -td ./ |
| # or |
| > tools/export-tsfile.sh -h 127.0.0.1 -p 6667 -u root -pw root -td ./ -q "select * from root.**" |
| # Or |
| > tools/export-tsfile.sh -h 127.0.0.1 -p 6667 -u root -pw root -td ./ -s ./sql.txt |
| # Or |
| > tools/export-tsfile.sh -h 127.0.0.1 -p 6667 -u root -pw root -td ./ -s ./sql.txt -f myTsFile |
| |
| # Windows |
| > tools/export-tsfile.bat -h 127.0.0.1 -p 6667 -u root -pw root -td ./ |
| # Or |
| > tools/export-tsfile.bat -h 127.0.0.1 -p 6667 -u root -pw root -td ./ -q "select * from root.**" |
| # Or |
| > tools/export-tsfile.bat -h 127.0.0.1 -p 6667 -u root -pw root -td ./ -s ./sql.txt |
| # Or |
| > tools/export-tsfile.bat -h 127.0.0.1 -p 6667 -u root -pw root -td ./ -s ./sql.txt -f myTsFile |
