关系数据操作符

数据库操作符用于执行特定操作的符号或关键字。

优先级

下表按照从最高优先级到最低优先级的顺序列出了 KWDB 支持的所有运算符。具有相同优先级的运算符是左关联的，这意味着这些运算符从左侧开始向右移动。

优先级	操作符	名称	操作符数目
1	.	成员字段访问运算符	双目
2	::	类型转换	双目
3	-	取反	单目（前缀）
3	~	按位取反	单目（前缀）
4	^	求幂	双目
5	*	乘	双目
5	/	除	双目
5	//	除（结果向下取整，3/2=1）	双目
5	%	求余	双目
6	+	加	双目
6	-	减	双目
7	<<	按位左移	双目
7	>>	按位右移	双目
8	&	按位与	双目
9	#	按位异或	双目
10	|	按位或	双目
11	||	字符串拼接	双目
11	< ANY，SOME，ALL	多值比较：小于	双目
11	> ANY，SOME，ALL	多值比较：大于	双目
11	= ANY，SOME，ALL	多值比较：等于	双目
11	<= ANY，SOME，ALL	多值比较：小于或等于	双目
11	>= ANY，SOME，ALL	多值比较：大于或等于	双目
11	<> ANY / != ANY，<> SOME / != SOME，<> ALL / != ALL	多值比较：不等于	双目
11	[NOT] LIKE ANY，[NOT] LIKE SOME, [NOT] LIKE ALL	多值比较：LIKE	双目
11	[NOT] ILIKE ANY，[NOT] ILIKE SOME，[NOT] ILIKE ALL	多值比较：ILIKE	双目
12	[NOT] BETWEEN	值不在指定范围	双目
	[NOT] BETWEEN SYMMETRIC	类似于 [NOT] BETWEEN，但未排序。例如，a BETWEEN b AND c 指的是 b <= a <= c，a BETWEEN SYMMETRIC b AND c 指的是 (b <= a <= c) OR (c <= a <= b)	双目
12	[NOT] IN	值不在指定的集合中	双目
12	[NOT] LIKE	匹配[或不匹配] LIKE 表达式，区分大小写	双目
12	[NOT] ILIKE	匹配[或不匹配] LIKE 表达式，不区分大小写	双目
12	[NOT] SIMILAR	匹配[或不匹配] SIMILAR TO 正则表达式	双目
12	~	匹配正则表达式，区分大小写	双目
12	!~	与正则表达式不匹配，区分大小写	双目
12	~*	匹配正则表达式，不区分大小写	双目
12	!~*	与正则表达式不匹配，不区分大小写	双目
13	=	等于	双目
13	<	小于	双目
13	>	大于	双目
13	<=	小于或等于	双目
13	>=	大于或等于	双目
13	!=，<>	不等于	双目
14	IS [DISTINCT FROM]	等于，考虑 NULL 值	双目
14	IS NOT [DISTINCT FROM]	不等于，a IS NOT b 相当于 NOT(a IS b)	双目
14	ISNULL，IS UNKNOWN , NOTNULL, IS NOT UNKNOWN	等价于 IS NULL 或 IS NOT NULL	单目（后缀）
14	IS NAN, IS NOT NAN	与浮点 NAN 值的比较	单目（后缀）
14	IS OF(...)	类型谓词（是不是某种类型）	单目（后缀）
15	NOT	逻辑非	单目
16	AND	逻辑与	双目
17	OR	逻辑或	双目
