    AND A.CREATED_BY = B.USER_ID
    AND A.LAST_UPDATED_BY = C.USER_ID
    AND TO_CHAR(A.CREATION_DATE, 'DD-Mon-YYYY') BETWEEN '01-Jan-2015'
        AND '08-Jan-2015'

Answer 1

您应该修复连接语法和格式。简单规则：永远不要在FROM子句中使用逗号。始终使用明确的JOIN语法。

但你的问题可能就是约会。日期比较为日期而不是字符串：

TRUNC(A.CREATION_DATE) BETWEEN DATE '2015-01-01' and DATE '2015-01-08'

DATE关键字非常方便，因为您可以将日期常量放在ISO标准YYYY-MM-DD格式中。

Answer 2

上述查询的正确编码是

'AND TRUNC(A.CREATION_DATE) BETWEEN TO_DATE('01-JAN-2015', 'DD-MON-YYYY') AND TO_DATE('08-JAN-2015', 'DD-MON-YYYY')`
