SQL JOIN on 2 tables with a list and column ID

SQL JOIN on 2 tables with a list and column ID

(OP)
How can I Join on KidsData and Fruitdescription table to get Fruit Name from Fruitdescription table rather than hard coding it.
this is what I can get to this far.

CODE

<cfquery name="kidsData">
 SELECT *
 FROM KidsData K
 LEFT JOIN Fruitdescription F ON F.ID = K.FruitData
 WHERE FruitData IS NOT NULL AND ID = #ID#
 </cfquery> 

Table: KidsData

CODE

ID Name FruitData
 1 Candy 100000
 2 Andy  001000
 3 Sarah 001010
 4 Gabby NULL
 5 Jack  000110 
Table: Fruitdescription

CODE

ID FruitName 
 0 apple
 1 orange 
 2 kiwi 
 3 banana 
 4 pineapple 
 5 grape 

RE: SQL JOIN on 2 tables with a list and column ID

Looks to me like your Fruitdescription.ID (PK) relates to KidsData.FruitData (FK), but the data in the tables does not look right because in one table you have values 0, 1, 2, ...5, and in another 100000, 001000, 001010, 000110
So, what is the data, what are the columns that relate one table to another?

Have fun.

There is a great need for a sarcasm font.

Thanks Andrzejek I understand and have corrected this. I guess i just needed someone to point that out. sorry and thanks.

RE: SQL JOIN on 2 tables with a list and column ID

To me FruitData looks like binary data, bits set, each bit for a fruit. For that to work fruits would need ids 1,2,4,8,16... and no join type would fit that schema. To get n:m relations between kids and fruits you should design a table fruitskidslike (for example) with tuples (kidid, fruitid).

Edit: Well, normal joins would work, but you need unusual join conditions, eg KidsData.FruitData & Fruitdescription.ID = Fruitdescription.ID, besides needing a default value for ID which doubles with each new fruit would limit FruitData to 32 or 64 fruits, depending on using integer or biginteger. IDs like they are would only work as 2^ID.

Bye, Olaf.
