Go中较少的冗长错误处理？

I have some Go code that queries a Database using the "database/sql" package. Most of these functions return: result, err or rows, err.

Because of this, you end up with many repetitive blocks like this:

if err != nil {
  // Handle Error
}

I've seen "cleaner" code for functions that only return err:

if err := SomeFunc(); err != nil {
  // Handle Error
}

I can't do this with these functions because the variable gets trapped in the scope when I need to access it in another query function later on.

Is there a way to clean up this go code?

They're only trapped in scope if they're declared in the if block using :=. If you declare them outside the if, they're in the outer scope:

var err error
var result SomeResultType
if result,err = SomeFunc(); err != nil {
    // Handle error
}
// Do something with result (or error if you want)
