counting null data in MySQL -

June 15, 2011

Assuming I have a table with data:

  name status Bob Single Bob Single Jane Empty Tina got married to the blank Shine

I want the status "single or data blank" to mean single. So if the data can be read as a single blank script and can be trusted together. So I can show results like this:

  Single Married 3 1

I have tried with this and it does not work: / P>

  SELECT SUM (IF (condition = 'single', 1,0)) AS Single, SAM (if (condition = 'married', 1,0)) Married AS    
  Use:  
  SELECT SUM (case when x. Status = 'single' OR x position is zero then 1 ELSE 0 END), as a single (Same (case when x.status = 'married' then 1 ELSE 0 END) from marriage (select t.name, T .status FROM YOUR_TABLE t) x

Cretegenine (); Engine. Retyme.io asset output (str, system text encoding. ASCII); Engine. Serial.io.setuperoutput (str, systemtext.edcoding.aspx); ScriptScope scope = engine.CreateScope (); ScriptSource src = engine.CreateScriptSourceFromString (testCode); Src.Execute (scope); Sorry for the silly question, it has come to know that there is a path used by IronPathon inside me.       The C # code was not correct. I ...

    Have you ever tried importing Classic C ++ / project into Qt Creator?   Say that I wanted to use some libraries in my GUI project, which must be created. how can I do this?
