动态Sql出错

SQL code

set @sql=N'SELECT a.ID,Title,AddDate ' +@tablename+ ' a INNER JOIN @Products b    ON CHARINDEX(b.keyWord,a.Title)>0    WHERE CONTAINS(Title,@contains)    GROUP BY a.ID,Title,AddDate    ORDER BY Sum(keyNum) DESC,COUNT(DISTINCT keyword),AddDate desc'print @sqlexec sp_executesql @sql

@tablename 接受参数作为表名
@Products是一个根据关键词顺序生成的权重表
@contains是关键词组合

最终输出的SQL语句为

SQL code

SELECT a.ID,Title,AddDate FS_News a INNER JOIN @Products b    ON CHARINDEX(b.keyWord,a.Title)>0    WHERE CONTAINS(Title,@contains)    GROUP BY a.ID,Title,AddDate    ORDER BY Sum(keyNum) DESC,COUNT(DISTINCT keyword),AddDate desc消息 102，级别 15，状态 1，第 1 行'a' 附近有语法错误。

[解决办法]
你用全局临时表，##Products
