mysql count not null

I'm trying to count non null row in a column but it's counting all the rows and and count the rows in a column that has string "1". I was able to count the rows in a column that has string "1" for the 1st column but on the 2nd one, it's count the "0" too. I've seen some articles here but it didn't resolved the issue.

SELECT NAME as Agent_Name, COUNT(case when Thumbs_Up= 1 then 1 else null end) as Thumbs_Up, COUNT(case when No_Solution_Found =1 then 1 else null end) as No_Solution, COUNT(case when Save is null then 0 else 1 end) as Total_Saves, FROM table GROUP BY NAME

Table:

Name | Thumbs_up | No_Solution_Found | Save Jonathan | 1 | 0 | Saved Mike | 0 | 1 | Null Peter | 1 | 0 | Null Mike | 1 | 0 | Saved Peter | 0 | 1 | Saved Mike | 1 | 0 | Saved Peter | 0 | 1 | Saved

Expected results:

Name | Thumbs_up | No_Solution | Total_Save Jonathan | 1 | 0 | 1 Mike | 2 | 1 | 2 Peter | 1 | 2 | 2

Try with `SUM`

instead of `COUNT`

SELECT NAME as Agent_Name, SUM(case when Thumbs_Up = 1 then 1 else 0 end) as Thumbs_Up, SUM(case when No_Solution_Found =1 then 1 else 0 end) as No_Solution, SUM(case when Save is null then 0 else 1 end) as Total_Saves, FROM table GROUP BY NAME

**SQL Tip: COUNTing NULL values – Benjamin's Blog,** The COUNT function can tell you the total number of rows returned in a result set (both NULL and non-NULL together depending on how it's used). For example: Using SELECT COUNT(*) or SELECT COUNT(1) (which is what I prefer to use) will return the total of all records returned in the result set regardless of NULL values. COUNT() function. The SQL COUNT() function returns the number of rows in a table satisfying the criteria specified in the WHERE clause. It sets the number of rows or non NULL column values. COUNT() returns 0 if there were no matching rows. Syntax: COUNT(*) COUNT( [ALL|DISTINCT] expression ) The above syntax is the general SQL 2003 ANSI standard syntax.

Since only the `Save`

column has `NULL`

s, I assume that's the column you have the problem with.

In your query you wrote:

COUNT(case when Save is null then 0 else 1 end) as Total_Saves,

That is, you're replacing `NULL`

by `0`

, which is a non null value and therefore is counted.

You presumable wanted to just write:

COUNT(Save) as Total_Saves

(And BTW, there is a comma after `as Total_Saves`

in your query, that doesn't belong there, as no other column expression follows.)
