ODBC foxpro ORDER BY multiple columns and a specific value issue

Question

I am working on a PHP program that reads from a FoxPro system. I am not allowed to modify the foxpro system as it is used for daily operations. So I have been using the ODBC driver with much success. The system I am currently working on requires me to create a union and show the data in a specific order. I have this query thus far:

SELECT arinvt01.item as recipe_group, arinvt01.item, arinvt01.descrip, arinvt01.cost, arinvt01.code as rcode
FROM arinvt01
WHERE code = 'RW'
UNION ALL
SELECT arrecp01.item as recipe_group, arinvt01.item, arinvt01.descrip, arinvt01.cost, arinvt01.code as rcode
FROM arinvt01
  INNER JOIN arrecp01 ON (arrecp01.recipe = arinvt01.item)
WHERE arrecp01.item IN (
    SELECT item
    FROM arinvt01
    WHERE code = 'RW'
)
ORDER BY recipe_group

The first SELECT fetches the RAW items from the table while the second SELECT fetches the items that use the RAW items (the table arrecp01 stores the associations for the items to the RAW items.) I am trying to list all items and categorize them by the RAW item so we can see all the items used for each RAW item. This means some items will be in more than one RAW item. I basically want the RAW item listed first for each recipe_group.

This returns (only showing 20 rows):

I imported these tables into MySQL for testing the data and in MySQL I can use this query to get the results as I need them.

SELECT arinvt01.item as recipe_group, arinvt01.item, arinvt01.descrip, arinvt01.cost, arinvt01.code as rcode
FROM arinvt01
WHERE code = 'RW'
UNION ALL
SELECT arrecp01.item as recipe_group, arinvt01.item, arinvt01.descrip, arinvt01.cost, arinvt01.code as rcode
FROM arinvt01
    INNER JOIN arrecp01 ON (arrecp01.recipe = arinvt01.item)
WHERE arrecp01.item IN (
        SELECT item
        FROM arinvt01
        WHERE code = 'RW'
)
ORDER BY recipe_group, (rcode = 'RW') desc

Adding , (code = 'RW') desc to the ORDER BY claus returns the results exactly as I need them. It also works in MySQL with ORDER BY recipe_group, CASE tcode WHEN 'RW' THEN 2 ELSE 3 END.

This returns (only showing 20 rows):

When I do this with the foxpro ODBC driver I get the following error: [Microsoft][ODBC Visual FoxPro Driver]SQL: ORDER BY clause is invalid. or when using the CASE I get [Microsoft][ODBC Visual FoxPro Driver]Command contains unrecognized phrase/keyword.

Update IIF throws the error: [Microsoft][ODBC Visual FoxPro Driver]SQL: ORDER BY clause is invalid.

Is it possible to get these results using the ODBC driver for foxpro? When I checked the syntax for the SELECT structure I noticed it does allow multiple column ORDER BY but like I said, I keep getting a error.

It should be noted that RAW items have a code of RW while most have no code and some have other values for code (EQ,EA,PA to name a few.) I only want RW to be listed first, the rest are irrelevant for this system.

Perhaps I am missing something so thought I'd ask here for some help on this matter.

Thanks

I am using the ADOdb Database Abstraction Library for PHP if this helps.

Answer 1

Well, first, it definitely smells of SBT Accounting system which I specialized in throughout the 90's. Anyhow, you should be able to get away with a LEFT-JOIN to the recipe table.

As for the order by, yes, VFP/ODBC (I have used the Microsoft Visual Foxpro OleDB provider with C#), allows you to use the alias column name as the group by clause, so here, I have the same recipe_group basis, but if there is a "recipe", the NVL() will grab the recipe item value instead of the actual item for grouping purposes. THEN grab the item, etc...

So the order by is based o the recipe_group, then the second is base on an IIF(). If the code is that of 'RW', then put it 1st (via 1) else second (via 2). So now, within, given recipe all the 1 entries are at the top, then all others. After that secondary level of sorting, then the items will be listed in alpha order.

SELECT
      NVL( rcp.item, ari.item ) as recipe_group,
      IIF( ari.code = 'RW', 1, 2 ) as RWSort,
      ari.item,
      ari.descrip,
      ari.cost,
      ari.code as rcode
   from
      arinvt01 ari
         LEFT JOIN arrecp01 rcp
            ON ari.item = rcp.recipe
   where
      ari.code = 'RW'
   order by
      recipe_group,
      RWSort,
      ari.item

Answer 2

First, try to use AS clause after IIF, e.g.:

IIF(ari.code = 'RW', 1, 2) AS field1

Also, you could possibly run your query w/o IIF statement, then run the following UPDATES:

UPDATE ari SET field1=1 WHERE code='RW'
UPDATE ari SET field1=2 WHERE code<>'RW'
