为什么我的if Else if语句在批处理脚本中不起作用？

Question

我的剧本

echo "Enter your choice (1 or 2 or 3) :"
set /p dbchoice=

IF %dbchoice EQU 1 ( 
    set dbtype="oracle"
) ELSE ( 
    IF %dbchoice EQU 2 ( 
        set dbtype="sqlserver" 
    )
) ELSE ( 
    IF %dbchoice EQU 3 ( 
        set dbtype="db2" 
    )
) ELSE (
    echo "Incorrect choice" 
)

我得到以下输出:

E:\csmilm>set /p dbchoice=
1
ELSE was unexpected at this time.
E:\csmilm>) ELSE (
E:\csmilm>

这里有什么问题？

将括号放在错误的位置.尝试:

IF %dbchoice EQU 1 ( 
    set dbtype="oracle"
) ELSE ( 
    IF %dbchoice EQU 2 ( 
        set dbtype="sqlserver" 
    ) ELSE ( 
        IF %dbchoice EQU 3 ( 
            set dbtype="db2" 
        ) ELSE (
            echo "Incorrect choice" 
        )
    )
)
