Question

我尝试运行此查询时出现上述错误

DECLARE @ColumnNames NVARCHAR(MAX)=''
DECLARE @SQL NVARCHAR(MAX)=''

SELECT @ColumnNames=Stuff((SELECT DISTINCT ',' + Quotename([COL1])
               FROM table1
               FOR XML PATH(''), TYPE).value('.', 'NVARCHAR(MAX)'), 1, 1, '')
SET @SQL = 'SELECT * FROM

( SELECT 
   [COL1]
  ,[COL2]
FROM 
  FROM table1 ) AS BaseData

PIVOT(
 COUNT([COL2])
 FOR [COL1]
 IN('+@ColumnNames +
 ')
) As PivotTable'


EXECUTE sp_executesql @SQL

请问我做错了什么？

Answer 1

查询中有两个from。

FROM FROM table1 --change this

关键字“FROM”附近的语法不正确。没有线索
