Unit Testing sqlboiler with sqlmock failing select - unit-testing

Question

I'm trying to mock a method written with sqlboiler but I'm having massive trouble building the mock-query.
The model I'm trying to mock looks like this:
type Course struct {
ID int, Name string, Description null.String, EnrollKey string, ForumID int,
CreatedAt null.Time, UpdatedAt null.Time, DeletedAt null.Time,
R *courseR, L courseL
}
For simplicity I want to test the GetCourse-method
func (p *PublicController) GetCourse(id int) (*models.Course, error) {
c, err := models.FindCourse(context.Background(), p.Database, id)
if err != nil {
return nil, err
}
return c, nil
}
with this test
func TestGetCourse(t *testing.T) {
db, mock, err := sqlmock.New()
if err != nil {
t.Fatalf("an error '%s' was not expected", err)
}
oldDB := boil.GetDB()
defer func() {
db.Close()
boil.SetDB(oldDB)
}()
boil.SetDB(db)
ctrl := &PublicController{db}
rows := sqlmock.NewRows([]string{"ID", "Name", "Description", "EnrollKey", "ForumID"}).AddRow(42, "Testkurs", "12345", 33)
query := regexp.QuoteMeta("SELECT ID, Name, Description, EnrollKey, ForumID FROM courses WHERE ID = ?")
//mockQuery := regexp.QuoteMeta("SELECT * FROM `courses` WHERE (`course AND (`courses`.deleted_at is null) LIMIT 1;")
mock.ExpectQuery(query).WithArgs(42).WillReturnRows(rows)
course, err := ctrl.GetCourse(42)
assert.NotNil(t, course)
assert.NoError(t, err)
}
But running this test only returns
Query: could not match actual sql: "select * from course where id=? and deleted_at is null" with expected regexp "SELECT ID, Name, Description, EnrollKey, ForumID FROM courses WHERE ID = ?"
bind failed to execute query
And I can't really find out how to construct it correctly.
How do I correctly mock the sqlboiler-query for running unit tests?
UPDATE
I managed to solve this by using different parameters in AddRow()
.AddRow(c.ID, c.Name, null.String{}, c.EnrollKey, c.ForumID)
and building the query differently
query := regexp.QuoteMeta("select * from `course` where `id`=? and `deleted_at` is null")
Now my issue is that in contrast to this method the others have a very large complexity in comparison with a large amount of complex queries (mainly insert-operations). From my understanding, sqlboiler-tests needs to mimic every single interaction made with the database.
How do I extract the necessary queries for the large amount of database interactions? I solved my problem by just using the "actual sql-query" instead of the previously used one but I'm afraid this procedure is the opposite of efficient testing.
