当我执行此动态查询时，我收到错误：

我执行了@SQL变量的输出（我通过PRINT命令获得）它完美运行。有什么我想念的东西。这之前执行得很完美，我在查询中做了一些更改，现在一切都搞砸了！我很快就会把它投入生产。
@SQL的部分输出是：

答案 0 :(得分：1)
即使变量@sql被声明为nvarchar（max），但是连接字符串select catid ...不是nvarchar（max），并且在被分配给@sql之前它被截断了。
set @sql = convert(nvarchar(max), '')
+ 'select catid ...'
这将确保在分配给@sql变量之前，连接字符串的结果是nvarchar（max）
另请注意，PRINT功能能打印出多少个字符取决于SSMS中的设置。无论设置如何，都有最大值，因此对于大型动态查询，您将无法打印完整查询
