Question

I have got a mysql table structure:

uid     company     value

Description:
uid -> unical id
company -> four letters code of company ie. AAAA, BIEW
value -> is a code of two different type of data: country or region, where:
country: "/[0-9]+\-/", ie. 49-, character at the end - means this is a region value
region: "/[0-9]+\_[0-9]+/", ie. 49_002 , 49_4, character _ means this is a country value

Now I want to SELECT all records WHICH:

• has a multiple company definitions, ie. AAAA' OR 'BIEW'
• has a multiple country definitions, ie. '49-' OR '5698-'
• first of countries above has specified region. I wan to search 49_01 only but not 49_03 and 49_965, which also “belongs” to 49- country
• second of countries '5698-' don’t have specified regions and should return only records where value='5698-'

The AAAA company has ‘filter’ that specify country/region records but BIEW has not any specified country/region values. The MYSQL query don’t work properly:

SELECT * FROM `table` WHERE (company='AAAA' OR company='BIEW') AND (value='5698-' OR value='49_01')

Answer 1

If I understand

SELECT * 
FROM `table` 
WHERE tourOP = 'AAAA' AND (val = '5698-' OR val = '49_01') OR tourOP = 'BIEW'
