ORA-00907 在 Crystal 中缺少右括号 - 在 Oracle Developer 中工作

Question

我有一个查询问题，它在 Oracle Developer 中工作正常，将 {?Month} 替换为 '2015-01-01'，但在 Crystal 中，当使用下面的查询时，它给了我错误 ORA-00907 missing right parenthesis。

参数

参数名称：月份

提示文字：输入月份

值类型：字符串（也试过日期）

默认值：2015-01-01 00:00:00AM

代码

Answer 1

你的前提是错误的；它在 SQL Developer 中不起作用。如果您复制并粘贴查询并将{?Month} 替换为'2015-01-01'，则会收到相同的ORA-00907 错误，报告在第14 行第1 列，即AND 本身。

这个：

BETWEEN
(trunc(to_date({?Month}, 'yyyy-mm-dd'),'month')
AND
last_day({?Month}))

括号在错误的位置 - 你试图做 between (x and y) 这不是正确的语法。应该是：

BETWEEN
trunc(to_date({?Month}, 'yyyy-mm-dd'),'month')
AND
last_day({?Month})

在联合的两半中。

（另外，可能相关的问题：Crystal Reports - Oracle 01861 Error。this 问题中的代码仍然不一致地处理参数 - 有时作为日期，有时作为字符串 - 所以它依赖于 NLS 设置按预期工作。）
