Apache Hive Like

Apache Hive Like(Like | rlike | not like | like not ) Apache Hive Like ---Rlike---- Not Like ----- Like Not1like的使用详解 1.语法规则: 1.A like B只能使用简单匹配符号 _%,”_”表示任意单个字符,字符”%”表示任意数量的字符 2.like的匹配是按字符逐一匹配的,使用B从A的第一个字符开始匹配 LIKE主要进行简单正则匹配。 4.案例演示:foobar LIKE foo的值为FALSE,而foobar LIKE foo___的值为TRUE, foobar LIKE foo%的值为TRUE。 如果数据包含分号,你想匹配它,则需要转义,像a;b 5.注意事项:否定比较时候用NOT A LIKE B(使用A NOT LIIKE B也可以),结果与like的结果时相对的。 abcde like b --匹配失败,左边第一个字母是a hive> select 1 from a2data.test where football like foot%; 1hive> select

    PostgreSQL LIKE 子句

    LIKE 子句中,通常与通配符结合使用,通配符表示任意字符,在 PostgreSQL 中,主要有以下两种通配符:百分号 %下划线 _如果没有使用以上两种通配符,LIKE 子句和等号 = 得到的结果是一样的 语法以下是使用 LIKE 子句搭配百分号 % 和下划线 _ 从数据库中获取数据的通用语法:SELECT FROM table_name WHERE column LIKE XXXX%;或者SELECT FROM table_name WHERE column LIKE %XXXX%;或者SELECT FROM table_name WHERE column LIKE XXXX_;或者SELECT FROM table_name WHERE column LIKE _XXXX;或者SELECT FROM table_name WHERE column LIKE _XXXX_;你可以在 WHERE 子句中指定任何条件 实例下面是 LIKE 语句中演示了 % 和 _ 的一些差别:实例描述WHERE SALARY::text LIKE 200%找出 SALARY 字段中以 200 开头的数据。

    BI-SQL丨LIKE

    LIKE操作符 LIKE操作符属于对WHERE子句的补充。通常我们使用WHERE子句都是知道具体的筛选条件,但是有些时候,也需要进行模糊查询,这种情况就需要LIKE。 SELECT * FROM 产品表 WHERE 商品名称 LIKE N%童% 结果如下: 例子2: 在PowerBI中,筛选出产品表中商品名称包含“鞋”的所有信息。 SELECT * FROM 产品表 WHERE 商品名称 LIKE N%鞋 结果如下: 例子3: 在PowerBI中,筛选出产品表中商品序号以“2”开头的所有信息。 SELECT * FROM 产品表 WHERE 商品序号 LIKE 2% 结果如下: 例子4: 在PowerBI中,筛选出产品表中商品分类不包含“婴儿类”的所有信息。 SELECT * FROM 产品表 WHERE 商品分类 NOT LIKE N%婴% 结果如下: 这里是白茶,一个PowerBI的初学者。

    SQLite Like 子句

    SQLite Like 子句 SQLite 的 LIKE 运算符是用来匹配通配符指定模式的文本值。如果搜索表达式与模式表达式匹配,LIKE 运算符将返回真(true),也就是 1。 table_name WHERE column LIKE %XXXX% or SELECT column_list FROM table_name WHERE column LIKE XXXX_ or 实例 下面一些实例演示了 带有 % 和 _ 运算符的 LIKE 子句不同的地方: 语句描述WHERE SALARY LIKE 200%查找以 200 开头的任意值WHERE SALARY LIKE %200% 查找任意位置包含 200 的任意值WHERE SALARY LIKE _00%查找第二位和第三位为 00 的任意值WHERE SALARY LIKE 2_%_%查找以 2 开头,且长度至少为 3 个字符的任意值 WHERE SALARY LIKE %2查找以 2 结尾的任意值WHERE SALARY LIKE _2%3查找第二位为 2,且以 3 结尾的任意值WHERE SALARY LIKE 2___3查找长度为

    SQL 使用like '%ABC' 和 like '%ABC%'的优

    一般情况下,sql中使用col_name like ABC%‘的情况才能使用到col_name字段上的索引。那么如果是col_name like %ABC%的情况,能否使用索引呢? 一、col_name like %ABC时的优化方法? 二、col_name like %ABC%时的优化方法?一般认为这种情况是不能使用索引的,但还是有一些优化方法可以使用。 TAB%;情况2、先创建reverse+substr组合函数索引,再使用like reverse‘%ABC’。 reverse(%TAB_COL);情况3、这种情况需要like的字段上存在普通索引,主要在SQL的写法上做改进。

    Linq Like的操作

    Selec * from table where id like %AD%Selec * from table where id like %ADSelec * from table where id like AD%上面的%是通配符,表示,该字段含有某个值,不知道的位置使用%代替。 Any single character not within the specified range () or set (). WHERE au_lname LIKE de% all author last names beginning with de and where the following letter is not LIKE @p0-- @p0: Input String (Size = 5; Prec = 0; Scale = 0) 对于Not Like,也很简单,加个取非就是。

    奇奇怪怪的ORA-01841错误,分析处理过程(全)

    2、CBO在计算NOT LIKE这类条件时,其计算思路是先计算出LIKE的选择率(类似于相等条件,是条件列中唯一值数量的倒数),然后用1-(like的选择率)就是NOT LIKE的选择率。 再来看对NOT LIKE的选择率:SQL> set autot traceonly expSQL> select * from test_tab1where c1 like X%; 2 3 Execution LIKE X%) 如上所示,我们看到对LIKENOT LIKE的估算,与我们的理解也是吻合的。 这时,CBO已经先执行条件“c1 NOT like ‘X%’”了。 同理,即使这时我们执行最初的两层SQL,其也应该是先执行条件“c1 NOT like ‘X%’”。

    not:只需要操作数 1,它将包含在 NOT() 中。例如, 将生成 。操作数 1 也可以是个描述多个表达式的数组。 not in:用法和 in 操作符类似,这里就不再赘述。like:第一个操作数应为一个字段名称或 DB 表达式,第二个操作数可以使字符串或数组, 代表第一个操作数需要模糊查询的值。 or like:用法和 like 操作符类似,区别在于当第二个操作数为数组时, 会使用 OR 来串联多个 LIKE 条件语句。 not like:用法和 like 操作符类似,区别在于会使用 NOT LIKE 来生成条件语句。 or not like:用法和 not like 操作符类似,区别在于会使用 OR 来串联多个 NOT LIKE 条件语句。

    Go is not (very) simple, folks

    But like I said, I’m not complaining about Go here, I don’t really mind the receiver argument (if I can I really would not like anyone to try to sell this to me as “simple” because this syntax is nothing but (I’m not even sure what all the implications of those features really are.)Secondly, I’d like to make Not handling the ambiguity like that seems like a designimplementation bug.
