存储过程因“将 varchar 转换为数字数据类型的算术溢出错误”而失败。即使我明确地转换所有字段也会出错

Question

I've spent an inordinate amount of time on getting this one stored proc to work, it's basically putting results from the query into an html format that is getting emailed.我花了很多时间来让这个存储过程正常工作，它基本上是将查询的结果放入通过电子邮件发送的 html 格式。 The query that the proc collects data from works fine and returns results as expected however when the output is attempted to be put into the table for the email it fails with the arithmetic overflow error. proc 从中收集数据的查询工作正常并按预期返回结果，但是当尝试将 output 放入 email 的表中时，它会因算术溢出错误而失败。

These are the results of the query:这些是查询的结果：

Any guidance would be extremely appreciated.任何指导将不胜感激。

In the failing line you essentially have:在失败的行中，您基本上拥有：

declare @sITTQty numeric(19,5); -- = ...
declare @sITT varchar(max); -- = ...
set @sITT = @sITT  
 + '</td><td style="border-style: solid; border-width: thin">' 
 + @sITTQty 
 -- + ...

So you are trying to add a numeric to a varchar.因此，您正在尝试将数字添加到 varchar。 This attempts to promote the varchar data to numeric, and that is why you are getting the error.这试图将 varchar 数据提升为数字，这就是您收到错误的原因。

Add an explicit cast to @sITTQty向@sITTQty添加显式强制转换

declare @sITTQty numeric(19,5);
declare @sITT varchar(max);
set @sITT = @sITT 
 + '</td><td style="border-style: solid; border-width: thin">' 
 +  cast(@sITTQty as varchar(19)) 
 -- + ...

Edit: You will have to do the same with @sDiff and @sSrlQty编辑：您必须对@sDiff和@sSrlQty执行相同的操作
