voltdb run sql file

  • Script files — You can run multiple queries or stored procedures in a single command using the file directive. The file directive takes a text file as an argument and executes all of the SQL queries and exec directives in the file as if they were entered interactively. Any showexplainrecall, or exit directives are ignored. For example, the following command processes all of the SQL queries and procedure invocations in the file myscript.sql:

    $ sqlcmd 1> file myscript.sql;

    If the file contains only data definition language (DDL) statements, you can also have the entire file processed as a batch by including the -batch argument:

    $ sqlcmd 1> file -batch myscript.sql;

    If a file or set of statements includes both DDL and DML statements, you can still batch process a group of DDL statements by enclosing the statements in afile -inlinebatch directive and the specified end marker. For example, in the following code the three CREATE PROCEDURE statements are processed as a batch:

    load classes myprocs.jar; file -inlinebatch END_OF_BATCH CREATE PROCEDURE FROM CLASS procs.AddEmployee; CREATE PROCEDURE FROM CLASS procs.ChangeDept; CREATE PROCEDURE FROM CLASS procs.PromoteEmployee; END_OF_BATCH

    Batch processing the DDL statements has two effects:

    • Batch processing can significantly improve performance since all of the schema changes are processed and distributed to the cluster nodes at one time, rather than individually for each statement.

    • The batch operates as a transaction, succeeding or failing as a unit. If any statement fails, all of the schema changes are rolled back.

  • Exit — When you are done with your interactive session, enter the exit directive to end the session and return to the shell prompt.

To run a sqlcmd command without starting the interactive prompt, you can pipe the command through standard input to the sqlcmd command. For example:

File
一个磁盘路径为:D:\\A\\b,在类中书写路径的时候应该写成:D:\\\\A\\\\b,前面的/是帮后面的/转义。关于Java的File.separator在Windows下的路径分隔符和Linux下的路径分隔符是不一样的,当直接使用绝对路径时,跨平台会暴出“Nosuchfileordiretory”的异常。比如说要在temp目录下建立
