Issue

use WillReturnResult(sqlmock.NewErrorResult(errors.New("mock db execute err"))) mock result err，but seem not available. mock code like this:
...
mock.ExpectBegin()
mock.ExpectExec("UPDATE").WithArgs(...).WillReturnResult(sqlmock.NewErrorResult(errors.New("mock db execute err")))
mock.ExpectCommit()
...

biz code like this:
...
result, err := b.WithContext(tCtx).Where(....).UpdateColumn(...)
if err != nil {
return err
}
if result.Error != nil {
return result.Error
}
return nil

Reproduction steps

Expected Result

if result.Error != nil {
return result.Error
}

Actual Result

step into 'return nil'
