Re: del not working in .bat file

Try using the CALL command inside the batch file. Without
the CALL command you run into problems where the next
statements do not get executed.

@echo off
Call RunSQL.bat
Call Del file.db

There's some ways to check the return value of the previous
statements as well, although I'm not sure if DEL returns anything.

Typing HELP CALL in a cmd.exe prompt yields...

<cmd.exe command="HELP CALL">
Calls one batch program from another.

CALL [drive:][path]filename [batch-parameters]

batch-parameters Specifies any command-line information required by the
batch program.

If Command Extensions are enabled CALL changes as follows:

CALL command now accepts labels as the target of the CALL. The syntax
is:

CALL :label arguments

A new batch file context is created with the specified arguments and
control is passed to the statement after the label specified. You must
"exit" twice by reaching the end of the batch script file twice. The
first time you read the end, control will return to just after the CALL
statement. The second time will exit the batch script. Type GOTO /?
for a description of the GOTO :EOF extension that will allow you to
"return" from a batch script.

In addition, expansion of batch script argument references (%0, %1,
etc.) have been changed as follows:


%* in a batch script refers to all the arguments (e.g. %1 %2 %3
%4 %5 ...)

Substitution of batch parameters (%n) has been enhanced. You can
now use the following optional syntax:

%~1 - expands %1 removing any surrounding quotes (")
%~f1 - expands %1 to a fully qualified path name
%~d1 - expands %1 to a drive letter only
%~p1 - expands %1 to a path only
%~n1 - expands %1 to a file name only
%~x1 - expands %1 to a file extension only
%~s1 - expanded path contains short names only
%~a1 - expands %1 to file attributes
%~t1 - expands %1 to date/time of file
%~z1 - expands %1 to size of file
%~$PATH:1 - searches the directories listed in the PATH
environment variable and expands %1 to the fully
qualified name of the first one found. If the
environment variable name is not defined or the
file is not found by the search, then this
modifier expands to the empty string

The modifiers can be combined to get compound results:

%~dp1 - expands %1 to a drive letter and path only
%~nx1 - expands %1 to a file name and extension only
%~dp$PATH:1 - searches the directories listed in the PATH
environment variable for %1 and expands to the
drive letter and path of the first one found.
%~ftza1 - expands %1 to a DIR like output line

In the above examples %1 and PATH can be replaced by other
valid values. The %~ syntax is terminated by a valid argument
number. The %~ modifiers may not be used with %*
</cmd.exe>

While it states that the CALL command is used to call BATCH files,
it also works in calling executables and scripts.

Without using the CALL command to execute executables, the next
statements in the batch file get lost (at least when one batch file calls
another, and it doesn't hurt - I don't think - to use it to call other files).

For instance try the following:

<test.bat>
@echo off
xcopy /v test1.bat test11.bat
test11.bat
xcopy /v test2.bat test22.bat
test22.bat
</test.bat>

<test1.bat>
@echo off
echo.
echo INSIDE test1.bat
echo.
call test2.bat
echo.
echo INSIDE test1.bat
echo.
</test1.bat>

<test2.bat>
@echo off
echo.
echo INSIDE test2.bat
echo.
pause
echo.
echo INSIDE test2.bat
echo.
</test2.bat>

You'll see that the first xcopy gets executed and then the test11.bat
executes, which calls test2.bat and that executes. But when it exits
the second xcopy never executes.

Hope this helps.
