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...
rowset_function 適用於:SQL Server 和 SQL Database。 指定其中一個資料列集函數 (如 OPENROWSET),其會傳回可代替資料表參考使用的物件。 如需有關資料列集函數清單的詳細資訊,請參閱資料列集函數 (Transact-SQL)。 使用OPENROWSET 和 OPENQUERY 函數來指定遠端物件時,主要取決於存取此物件之 OLE DB 提供者的...
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,value1, value2, ...是透视...

5分钟学会SQL SERVER PIVOT操作 PIVOT和UNPIVOT PIVOT 通过将表达式中的一个列的唯一值转换为输出中的多列(即行转列),来轮替表值表达式。PIVOT 在需要对最终输出所需的所有剩余列值执行聚合时运行聚合。与 PIVOT 执行的操作相反,UNPIVOT 将表值表达式的列轮换为行(即列转行)。
PIVOT语法可以等效为group by + aggregate function + filter的结合。以下面这个例子为例 SELECT ... FROM ... PIVOT ( agg1 AS a, agg2 AS b, ... FOR (axis1, ..., axisN) IN ( (v11, ..., v1N) AS label1, (v21, ..., v2N) AS label2, ...
