在窗口批处理中将返回值设置为变量

Question

如果值大于1，我如何使用if else语句来回显？

@echo off

setlocal
set "sql=c:\xampp\mysql\bin\mysql.exe"
for /f "usebackq" %%a in (`%sql% -u root -ss -e "select COUNT(*) FROM mytable"      mydatabase`) do set TESTVAR=%%a

if %TESTVAR% GEQ 1 (echo Database has already existed.) else echo import 

pause

Answer 1

有点像这样：

@echo off
setlocal
set "sql=c:\xampp\mysql\bin\mysql.exe"
for /f "usebackq" %%a in (`%sql% -u root -ss -e "select COUNT^(*^) FROM browser" form_generator`) do set TESTVAR=%%a
if %TESTVAR% LSS 1 echo whatever
pause
