将数值转换为数值类型的算术溢出错误

Question

In the past couple of weeks my client's customers have been receiving the error below when running any sort of query on their website. I am not proficient with SQL, so any help would be appreciated.

Stack Trace:

Answer 1

The places to look are either:

1. There is an update query that is trying to change an int (or some other small number datatype) with a larger number datatype (like a single or a double).
2. It is trying an isert with the same conditions.

Focus on looking for something changing values with numeric fields and check to see what datatypes are trying to make those changes. When you see a mismatch, that is most likely your culprit.

Answer 2

将sum(col1)更改为sum(cast(col1 as bigint))即可动态更改当前列的类型，或在表设计模式下进行更改。
