ExecuteSqlInterpolated/ExecuteSqlRaw 参数在 asp.net 内核中错误地传递到数据库

Question

I am attempting to use ExecuteSqlInterpolated to update my database. However, it seems that there is a problem with my SQL parameters. Running the following code correctly updates intField1 and intField2, however stringField becomes the string "@p0".

_context.Database.ExecuteSqlInterpolated($"UPDATE table SET stringField='{someString}', intField1={someInt}, intField2={someOtherInt} WHERE id='{id}'");

I have already verified that my variables contain the desired values when the string is passed to the method. I understand that @p0 is what SQL uses to represent the first parameter in the query, but why isn't it being replaced by the string I gave it? I have also tried using ExecuteSqlRaw but ran into the same issue. My knowledge of SQL is limited at best, I know just enough to get by in web dev, so I'm guessing I'm committing some simple error in crafting the query here, but obviously I'm not sure.

I know it's late but just don't use quotation mark with your parameters, specially where you use int data-type (delete single quotes)

_context.Database.ExecuteSqlInterpolated($"UPDATE table SET stringField={someString}, intField1={someInt}, intField2={someOtherInt} WHERE id={id}");
