我的更新语句哪里有问题呢

为什么会报错不知道sql语句哪里出问题了，感觉写的是对的啊

    <update id="updatemoney">
update sys_money
<set>
    <if test="bsalary!=null">
        bsalary = #{bsalary}
    if>
    <if test="psalary!=null">
        psalary = #{psalary}
    if>
set>

        <where>
            id =#{id}
        where>
    update>

错误提示：

Error updating database. Cause: java.sql.SQLSyntaxErrorException: 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 'psalary = '0'

     WHERE id =1' at line 5

The error may exist in file [D:\vuedemo\salaryManage\target\classes\mapper\UserMapper.xml]

The error may involve defaultParameterMap

The error occurred while setting parameters

Cause: java.sql.SQLSyntaxErrorException: 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 'psalary = '0'

更新多个字段的时候，字段中间要加个逗号
