I have a 40,000 record database which consists of the following fields:

ID, STATE, TYPE

The type field contains one of 5 distinct values.

I want to run a query where I group the records by state and also get counts of each distinct type value. The resulting output I want is as follows:

STATE, TYPE_A, TYPE_B, TYPE_C, TYPE_D, TYPE_E, TYPE_ALL

type_all is a total count of records for that state.

My SQL Thus far looks like this:

SELECT TABLE1.STATE,
COUNT(TABLE1.type) as TYPE_ALL,;
COUNT(TABLE1.type='A') as TYPE_A,;
COUNT(TABLE1.type='B') as TYPE_B,;
COUNT(TABLE1.type='C') as TYPE_C,;
COUNT(TABLE1.type='D') as TYPE_D,;
COUNT(TABLE1.type='E') as TYPE_E;
FROM TABLE1;
GROUP BY TABLE1.STATE

However, all count values are the same. Any ideas of what I'm doing wrong and how I might fix it?

Thanks, in advance, for your help!

Can't tell top of my head what's wrong with the SQL stement.
However, I do have an alternative:

Code:
SELECT TABLE1.state, ;
	SUM( IIF(TABLE1.type = "A", 1, 0) ) AS type_a, ;
	SUM( IIF(TABLE1.type = "B", 1, 0) ) AS type_b, ;
	SUM( IIF(TABLE1.type = "C", 1, 0) ) AS type_c, ;
	SUM( IIF(TABLE1.type = "D", 1, 0) ) AS type_d, ;
	SUM( IIF(TABLE1.type = "E", 1, 0) ) AS type_e  ;
  FROM TABLE1 ;
 	GROUP BY TABLE1.state ;
  INTO CURSOR result

Should give the desired result...

I guess in your original SQL statment you should add an ORDER BY.

They cling emotionally to code and fix development rather than choosing practices based on analytical assesments of what works best.

Use the query designer and create a CROSS TAB query grouped by STATE and TYPE. That way, you don't have to hard-code each TYPE in your query and should you add more TYPEs, you don't have to change your code.
