我遇到以下代码的问题
public long findDataCount(EntityUiBean entityUIBean){

}

}

} else
sql.append(" and a.entity_type !='corporate' and a.entity_type !='vendor'");
MY_LOGGER.info("SQL Query is : "+sql.toString());
try {

} catch (Exception re) {
MY_LOGGER.error("SERVICE:AuLoginDao.checkLoginStatus Fail sql=" + sql, re, 1);
throw re;
}
return count;
}
堆栈跟踪是：

我似乎无法理解问题的原因。查询在MySQL中成功执行，但通过代码抛出异常。请帮我查询。
答案 0 :(得分：1)
您有WITH个关键字代替AND（我从您的堆栈跟踪中获取了查询）
SELECT Count(a.id)
FROM entity_listing a
LEFT OUTER JOIN relation_master d
ON d.entity_id = a.id,
entity_location b
LEFT OUTER JOIN city_master c
ON c.id = b.city_id
WITH --Here
b.entity_id = a.id
AND a.entity_type != 'corporate'
AND a.entity_type != 'vendor'
不确定你想要实现的目标，但AND是预期的（现在应该编译）
SELECT Count(a.id)
FROM entity_listing a
LEFT OUTER JOIN relation_master d
ON d.entity_id = a.id,
entity_location b
LEFT OUTER JOIN city_master c
ON c.id = b.city_id
AND b.entity_id = a.id
AND a.entity_type NOT IN ( 'corporate', 'vendor' )
注意：您可以使用NOT IN运算符代替多个!=条件
更新：
您已将明确的JOIN语法与逗号分隔的旧样式结合使用Join语法可能是问题所在。试试这个
SELECT Count(a.id)
FROM entity_listing a
LEFT OUTER JOIN relation_master d
ON d.entity_id = a.id
JOIN entity_location b
ON b.entity_id = a.id
LEFT OUTER JOIN city_master c
ON c.id = b.city_id
AND a.entity_type NOT IN ( 'corporate', 'vendor' )
