In MSSQL, we all know that pivot can be used to statistic data, and to implement the pivot table function like Excel.First, our usual usage in the MSSQLServer1. SQL Server database Test---Creating a test table create

In today's article I would like to discuss a special T-SQL language structure in SQL Server-the pivot operator introduced from SQL Server 2005. I often cite this and the language structure is the most dangerous one in

Pivot is used to rotate column values to column names (row to column)Grammar:Table_sourcepivot (Aggregation function (value_column) for Pivot_columnin (Unpivot used to set the column value to a column (that is, a column change)Grammar:Table_sourceunpivot (value_columnfor pivot_columnin (Note: PIVOT, Unpivot is the syntax for SQL

First of all, let's look at one of the steps here that translates into banner, which requires pivot, step-by-step Then look at the overall query results for the two query methods after the main table join So take a look at the latter query method is also through the industry after the conversion to do the join execution plan, you can see only the Word table

Label:Original: Use of the SQL Server 2005 pivot operatorThe pivot,unpivot operator is one of the new features supported by SQL Server 2005 and is primarily used to implement row-to-column conversions. This article mainly describe

: Table_source Pivot (aggregate function (Value_column) pivot_column for (columnlist)) A little explanation: Table_source: Is the table we want to convert. Pivot_column: Is the column name for row to column. Value_column: Is the value of the column after the conversion. Columnlist is the column to be generated. This is also the case with pivot, which can be used
