The PIVOT function in SQL Server is not used very often in projects I work on, but can be extremely useful for specific kinds of pages, especially when consumed in ASP.NET using GridView objects. Some people struggle with PIVOT on one field, the online documentation should be sufficient for...
Pivot函数的基本语法如下: SELECT...FROM...PIVOT(aggregate_function(column_to_aggregate)FORcolumn_to_pivotIN(value1,value2,...))ASalias; 1. 2. 3. 4. 5. 6. 其中,aggregate_function是聚合函数(如SUM、COUNT、AVG等),column_to_aggregate是需要进行聚合的列,column_to_pivot是需要进行透视的列,valu...
<aggregation function>(<column being aggregated>) FOR [<column that contains the values that will become column headers>] IN ( [first pivoted column], [second pivoted column], ... [last pivoted column]) ) AS <alias for the pivot table> <optional ORDER BY clause>; 示例1:pivot 1.数据准...
aggregate-function(<column>)FOR<pivot-column>IN(<value1>,<value2>,...,<valuen>) )AS<alias>WHERE... 注意:FOR<pivot-column>这个是不支持表达式的,如果需要,请通过子查询或者视图先预处理。 Pivot 例子1:先构造一个子查询,然后根据CHANNEL列进行转置,源表sales_view里面可能有很多列,不需要列先通过子...
(<SELECT query that produces the data>)AS<alias for the source query>PIVOT(<aggregation function>(<column being aggregated>)FOR<column that contains the values that become column headers>IN(<first pivoted column>,<second pivoted column>, ...<last pivoted column>) )AS<alias for the pivot ...
...因此我们可以编写汉字转拼音的函数 GetPY 进行进一步操作,如下图: 在搜索时,我们通过该函数进行了一次转化,以得到预期结果,另外通过在查询字段列表里进行转化验证,可以看到 PY 字段对应 NAME...函数实现 打开SQL SERVER 查询分析器,执行如下代码: create function [dbo]...end return @str1--返回输入汉字的...
