HSQLDB

Question

我是 hsqldb 的新手。我在调用 BITANDNOT() 函数时遇到以下错误。

Caused by: org.hsqldb.HsqlException: user lacks privilege or object not found: BITANDNOT

例如，我在此函数调用中仅传递两个值

BITANDNOT(field1, val1)
Here,
field1 is field in table
val1 is string value of an Integer object

我有点被这个例外困住了。如果有人有 hsqldb 的经验，请帮助。

提前致谢。

Answer 1

v2.2.6 中引入了新的位运算函数。

如果你不能应付 2.3，那就去 2.2.9。它对我有用。

HSQLDB - 未找到按位运算方法 BITANDNOT()

HSQLDB - bitwise operation method BITANDNOT() is not found
