How to make for loop in windows batch file run in name order
I have a windows batch file that does this:
for %%s in (*.sql) do call
It loops through all the sql script in a folder.
In the folder the file names are like:
s4.06.01.sql
s4.07.01.sql
s4.08.01.sql
s4.10.01.sql
s5.01.sql
But the for loop goes through the files randomly (not in the name order), it first run s5.01, then s4.06, then s4.08, then s4.10, then s4.07. How can I make them run in the name order?
It used to work, but now it 开发者_Go百科doesn't. What may cause this problem?
Jerry's answer might very well be what is causing the problem.
You might solve it by changing
for %%s in (*.sql) do call
to
for %%s in (dir"*.sql ^| sort) do call

The posted solution does not work as is on a Windows 8 machine (perhaps it did back then with Windows XP but I have no idea).
Following is a working solution using Windows 8 command prompt.
for /f "tokens=*" %%s in ('dir /b *.sql ^| sort') do echo %%s
If memory serves, it will operate on the files in the order they're returned by the file system. As such, if you run it on a disk partition that's formatted with NTFS, the names will be returned in sorted order so they'll be processed in sorted order. If the disk partition is formatted with something like FAT or FAT32, the names will be retrieved (and processed) in a more or less random order.
I too had to deal with spaces in the filenames, so I added quotes around the input variable like so:
for /f "tokens=*" %%s in ('dir /b *.sql ^| sort') do echo "%%s"
In my case it was SQLCMD, with the scripts in a subdirectory, like so:
SET "machineName=localhost"
for /f "tokens=*" %%f in ('dir /b PostDeployScripts\*.sql ^| sort') do sqlcmd -E -S%machineName% -i"PostDeployScripts\%%f"
