WINFORM算术溢出错误将表达式转换为数据类型int

Question

I am running an SQL Server query in a WINFORM to get data and fill a DataGridview.

I am searching for certain files extension.

I am using for examples like '%exe' and get the results, for this and every file type there is in the database for examples; jpg, apk, cab etc…

The problem that I am having is when I search for file extension .dll every time I get the error: “arithmetic overflow error converting expression to data type int.”

I can run the same query inside SQL Server management Studio and search for the dll extension and get the results successfully.

Adding details:

I am also have a counter and Joins.

I can't paste the actual code with the tables name, so I substituted the names of the tables and columns.

select 
 t.column1, t.column2, t.column3 ,COUNT([column4]) as [Total]
 FROM table1 j 
 join table2 f on f.column1 = j.column1 and j.column7 = 1 
 join table3 t on j.column3 = t.column6
 join table4 lc on t.column6 = lc.column6
 where j.column2 like '%dll' Group by t.column1, t.column2, t.column3 order by Total desc

As I mention before, the query runs ok in the WINFORM C# for every other file extension that I enter and search for with the exception of the DLL in the.

Thanks again.

Any ideas? Regards

First of all, I want to thank everyone that took the time to read this thread.

The solution was to change COUNT to COUNT_Big

Once I did this my query executed successfully searching for the dll file extension.
