Mysql custom order

See the following orders table from the sample database. I need to sort of a given query by fixed column values. I have a column named status and which holds the following values 4. I must disagree: controlled insertion order cannot be the solution. Queries must not rely on the order the rows are in the table, because they can change anytime for any reason. I would rather find a way to achieve it using order by clause then to enhance software consistency.


For columns that could potentially have duplicates, specify a secondary (or tertiary etc.) ORDER BY column name. It orders the result set by specified column list. When used with character data type columns it sorts data in dictionary- order.

One easy way could be to make a join with the master table. Tag: mysql ,select, order. Any help would be appreciated.


Sharing your query and CREATE TABLE statement would help us answer your question more specifically. It all works fine, but the problem is the blank value in the drop down menu shows up last. I am assuming this is because of default ordering. So I am wondering how I could order it so that NULL (or even a varchar of none) would show up before the numbers, without changing the order in which numbers appear (from smallest to greatest).
