使用Windows批处理脚本将SQL表导出到CSV文件

Question

I am trying to create a windows batch file to export data from an SQL file to a CSV file.

I have an SQL file in %MYHOME%\\database\\NET-DB.sql which contains data that is:

NET-DB.sql

insert into net_network (id, a_id, alias, address, domain, mask) values('NET_10.10.1.0_10', 1, 'Local Network', '10.10.1.0', '', '255.255.252.0');

What I have tried so far in exporting the data from net_network table into a CSV file in my .bat file is with this command:

export.bat

if not exist "%MYHOME%\net\NUL" mkdir "%MYHOME%\net"
COPY net_network TO '%MYHOME%\net\CSV-EXPORT_FILE.csv' DELIMITER ',' CSV HEADER;
pause

Since that does not work for me, what should be the correct approach for this implementation? Any help will be much appreciated.

Answer 1

Use SQLCMD

You need to modify the code to make it work in your environment, but here goes.

if not exist "%MYHOME%\net\NUL" mkdir "%MYHOME%\net"
cd "C:\your path\to\sqlcmd"
sqlcmd -S YourDBServer -d DB_NAME -E -Q "select id, a_id, alias, address, domain, mask from net_network" 
       -o "CSV-EXPORT-FILE.csv" -s"," -w 255

Some explanations:

-S The database server to connect to.

-d Name of the database to connect to.

-Q Query to run, can also be insert, delete, update etc.

-o select the output file

-s "," separated by comma

-w column width, this has to be as big as your largest columns characters.
