关于java错误的子查询

嗨，伙计们，我试图在java上查询数据库中的access数据，但当我编译时，错误是语法错误在或接近v，当我尝试在postgresql上编译我的查询时，它可以工作，数据可以显示，但当我在eclipse上编译时，它不能

这就是问题所在

谢谢，这是个打字错误。确保在每一行的末尾留一个空格

+"AND v.master_user_id = a.master_user_id "

在第一个查询中，您遗漏了一个空格

+"AND v.master_user_id = a.master_user_id"
+ "AND v.master_role_id = a.master_role_id ) as in_progress, "

现在的问题是

...AND v.master_user_id = a.master_user_idAND v.master_role_id =....

SQL引擎认为.master_user_id是一个列。所以下一个v是个问题。这就是错误的原因

在v或v附近出现语法错误

也许可以尝试简化您的查询，缩小问题的范围？这个问题与promefaces无关，因此我删除了标记good spotting！不幸的是，还有更多的地方在这条线的末尾缺少一个空格。
