China DOS Union

For example, how to find out the installation path of SQL Server?
I used the following statement, but there are other information besides the path. Is there any other method to directly find out the path?
-----------------------------------------------------------------------------------------------------------------
FOR /F "delims=" %%i IN ('@reg query "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSSQLServer\Setup" /v
SQLPath') DO @SET mypath=%%i
-----------------------------------------------------------------------------------------------------------------

Is it that I didn't describe clearly? I want to find out the installation path of installing SQL Server 2000 and then pass it to a variable. But according to the above method, what is obtained is " SQLPath REG_SZ C:\Program Files\Microsoft SQL Server\MSSQL.2\MSSQL ". I want to get C:\Program Files\Microsoft SQL Server\MSSQL.2\MSSQL, how should the batch processing be written? (Note: there is no space at the end)

```@echo off
for /f "skip=4 tokens=1,2 delims=:" %%a in ('reg query "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSSQLServer\Setup" /v "SQLPath"') do (
set SQLL=%%a
set SQLR=%%b
)
set SQL=%SQLL:~-1%:%SQLR%
echo %SQL%
```

Thanks, HAT.
People on CN-DOS are really helpful. I spent the whole afternoon without getting results, but didn't expect it to be done in 10 minutes here.

Please check that the installation path should be in the local variable path

To everest79: The value taken from the path doesn't seem to be the installation path. I want to get the storage directory of the SQL Server database files

to HAT: That code is a bit strange. It's retrieved on one machine, but not fully retrieved on another. Could it be that reg really misses characters? But it's not a Chinese path?
Also, I want to ask, when is %%b evaluated?

What is the system version for machines with missing characters?

You can go to the Registry Editor to see if there are really Chinese characters:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSSQLServer\Setup\SQLPath

Also, will the code that calls VBS to read the registry mentioned in the group last night have the same problem?

There is no Chinese. Using the code from the third floor, this machine has:
~-1SQLR\Data
--------------------------------------------------------
@echo off
>"%temp%\my.vbs"
echo Set WshShell = WScript.CreateObject("WScript.Shell")
>>"%temp%\my.vbs"
echo WScript.Echo WshShell.RegRead("HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSSQLServer\Setup")
for /f "delims=" %%a in ('cscript /nologo "%temp%\my.vbs"') do set SQL=%%a
echo %SQL%
pause
--------------------------------------------------------------------------------------------
This code doesn't see the effect, it flashes by.

What is the version of the machine with the problem?
Run this code on that machine and post the result:
for /f "skip=4 tokens=1,2 delims=:" %%a in ('reg query "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSSQLServer\Setup" /v "SQLPath"') do ( set SQLL=%%a set SQLR=%%b ) set SQL=%SQLL:~-1%:%SQLR% echo %SQL% pause

Should the code for calling VBS be like this:
@echo off >"%temp%\my.vbs" echo Set WshShell = WScript.CreateObject("WScript.Shell") >>"%temp%\my.vbs" echo WScript.Echo WshShell.RegRead("HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSSQLServer\Setup\SQLPath") for /f "delims=" %%a in ('cscript /nologo "%temp%\my.vbs"') do set SQL=%%a echo %SQL% pause

The first code running result:
~-1SQLR\Data
--------------------------------------------------------------------------
The second code successfully fetched:
C:\Program Files\Microsoft SQL Server\MSSQL.2\MSSQL
---------------------------------------------------------------------------
I originally wanted to obtain the path of the Date file under the sqlserver directory, that is, the directory where database files are stored.
Now when SQL Server 2000 is installed, the data directory and the installation directory are separated.
The SQLPath found in HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSSQLServer\Setup\SQLPath is the installation directory. I don't know which item in the registry should be checked to find the directory where database files are stored?

The `/nologo` option for `cscript` is used to suppress the Microsoft Visual Basic Script host logo from being displayed when the script is run.

Re 11th floor:
Save the first paragraph of the code on the 10th floor as test.bat, double-click to run it, and post the complete result for us to see.

Re 12th floor:
Check the help

I put it on the desktop and ran it. Just now, I copied it to d:\ and it didn't work...
==================================================
Another question: Is there a mistake in copy xx.txt %SQL% ? (xx.txt is a file in the same directory, SQL is a variable assigned a path)

Start
Run
cmd
reg query "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSSQLServer\Setup" /v "SQLPath"

What is the result? If there is no result, please check if this machine has SQL Server 2000 installed.

When the path has spaces, remember to add quotes:
copy "xx.txt" "%SQL%"
