JSqlParser：CCJSqlParserUtil.parse（sql）异常;

Question

在2008年SQLSERVER：

/** 
sql1：use Subquery AS 'PIVOT' ResultSet 
*/ 
SELECT * FROM (
    SELECT a.Station_ID stationId, b.Factor_Code factoryCode, a.Value value 
    FROM T_Data_Real a 
    LEFT JOIN T_Bas_Factor b ON a.Factor_ID = b.Id 
)f 
PIVOT (max(f.value) for f.factoryCode in (ZD, COD, SW, PH))d 

/** 
sql2：use with 
*/ 
WITH A AS(
    SELECT a.Station_ID stationId, b.Factor_Code factoryCode, a.Value value 
    FROM T_Data_Real a 
    LEFT JOIN T_Bas_Factor b ON a.Factor_ID = b.Id) 
SELECT * FROM A 
PIVOT (max(value) for factoryCode in (ZD, COD, SW, PH))d 

执行在SSMS上述两个语句具有相同的结果。

但是当我使用的方法来格式化SQL 1和2：

CCJSqlParserUtil.parse(sql) 

第一个抛出异常，我不能使用子查询AS“PIVOT”结果集。

异常消息是这样的：

请帮帮我！

Answer 1

这是JSqlParser的问题。我为此提出了一个问题（https://github.com/JSQLParser/JSqlParser/issues/473）。

问题是与数据透视表结合使用子查询的别名。

因此，这应该与您当前的版本：

select * from (select * from mytable) pivot (...)

固定它。尝试使用JSqlParser 1.2-SNAPSHOT。这个版本尚未部署，你必须自己编译它。
