 ## Import Using Script
 
-TDengine CLI `taos` supports `source <filename>` command for executing the SQL statements in the file in batch. The SQL statements for creating databases, creating tables, and inserting rows can be written in single file with one statement on each line, then the file can be executed using `source` command in TDengine CLI `taos` to execute the SQL statements in order and in batch. In the script file, any line beginning with "#" is treated as comments and ignored silently.
