How do I run a script using a BAT file?

问题

I would like to have a BAT file open a sql server script. Currently I have this code in the sql file:

declare @path varchar(255), @mydb varchar(50)
SELECT @mydb = 'timeclockplus'
select @path = 'C:\Program Files\Microsoft SQL Server\MSSQL.2\MSSQL\Backup\' 
            + @mydb + '-' + convert(varchar(8),getdate(),112) + '.bak'
BACKUP DATABASE @mydb TO DISK = @path

How do I open this SQL file from a BAT file?

I am currently trying to run it like this:

C:\Program Files\Microsoft SQL Server\80\Tools\Binn\osql -E 
   -S Sql server-hl7\timeclockplus timeclockplus.sql -oresults.txt

but OSQL does not exist in the BINN directory,

回答1:

You should invoke the sqlcmd command-line tool from your batch file. Assuming your sql file is "backup.sql", the command line would be something like:

sqlcmd -E -S yoursqlinstance -i backup.sql

-E uses trusted connection, replace with -U and -P if you need to specify a SQL username and password. See also this article with examples.

回答2:

sqlcmd -S 127.0.0.1 /E -i MySqlScript.sql

Replace /E with /U and /P if you don't have trusted connection

If you want a much better answer, here it is:

@echo off
SETLOCAL ENABLEDELAYEDEXPANSION
:: batch file for sql query
SET FIELDVAL=Empty
SET DBNAME=MYDB
SET SQLSTRING=SELECT column_name(s)^
 FROM table_name1^
 INNER JOIN table_name2^
 ON table_name1.column_name=table_name2.column_name^
 AND table_name2.field=%FIELDVAL%
ECHO !SQLSTRING!

ECHO.
sqlcmd.exe -b -S localhost -E -d !DBNAME! -Q "!SQLSTRING!" -W
ECHO Query is done. Hit any key to close this window....
pause>nul
