SQL嵌套和/或语句

问题描述 投票:0回答:1

我被困在一条SQL语句上。我正在尝试获取以下内容:

从rentedTab的WHERE中选择字段属性与propertyIDTr相匹配

AND

the rentedHouseMoveInDateTr is less than or equal to today AND
the rentedHouseMoveOutDateTr is NULL 

OR

the rentedHouseMoveInDateTr is less than or equal to today AND 
the rentedHouseMoveOutDateTr is greater than today's date.

如果返回结果,则该属性被占用否则是空的

我正在使用的SQL语句是:

SELECT * FROM rentedHouseTbl,其中propertyIDTr ='1'AND((rentedHouseMoveInDateTr <= CURDATE()AND rentedHouseMoveOutDateTr为NULL)或(rentedHouseMoveInDateTr <= CURDATE()AND rentedHouseMoveOutDateTr> CURDATE())] >>

但是我没有得到预期的结果。任何帮助,将不胜感激!
