我遇到了无法执行命令的问题，如下所示：

Unable to execute command:
create table `payrollmanagementsystem`.DEDUCTION
(
    CODE VARCHAR(50) not null primary key,
    NAME VARCHAR(50),
    SALARYPERDAY DOUBLE PRECISION,

    KWSP DOUBLE PRECISION,
    TOTALDEDUCTION DOUBLE PRECISION
)
You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'LEAVE INT,
    KWSP DOUBLE PRECISION,
    TOTALDEDUCTION DOUBLE PRECISION
)' at line 6

Answer 1

因此： LEAVE - keyword

Answer 2

正如其他人所指出的，LEAVE是一个关键词。要解决您的问题，请使用反引号：

`LEAVE` INT,

请注意 CODE 也是关键字，但在这种情况下，它不会导致问题。逃避列名称仍然是一种很好的做法。
