Converting ID values in substring of varchar to it's lookup values - sql

Question

I have a SQL column of type varchar that is meant to contain SQL conditions, eg (3 rows below):
WHERE Language = 1 OR Region = 10
WHERE Color= 3 OR Region = 10
WHERE Status = 1 OR Region = 10 AND Language = 1
I need to create a query to get the lookup values of these that can be sent to any non technical person. The output would be:
WHERE Language = English OR Region = Canada
WHERE Color= Red OR Region = Canada
WHERE Status = Active OR Region = Canada AND Language = English
I know I can first put all the lookups in a temp table and then use the REPLACE function, but I was wondering if there's any better (and shorter) way to do this? Any help would be appriciated.
Thanks.

Answer 1

I would create subquery column values ready to replace originals, f.eks for Regions:
SELECT
CONCAT('%Region = ', Region,'%') ConditionToJoin,
CONCAT('Region = ', Region) ConditionToFind,
CONCAT('Region = ', RegionName) ConditionToReplace
FROM Regions
The join this sub query with condition rows using LIKE operator and ConditionToJoin column.
There is also a question if you need to handle situations like:
Region=1
Region =1
etc...
Alternatively you could write user function to wash data and perform all replacements, something like:
CREATE FUNCTION replaceLookups(#condition VARCHAR(MAX))
RETURNS VARCHAR(MAX)
BEGIN
#string_replacement VARCHAR(MAX), #string_pattern VARCHAR(MAX);
SET #string_pattern = SELECT TOP 1 CONCAT('Region = ', Region) FROM Regions WHERE #condition LIKE CONCAT('%Region = ', Region, '%')
SET #string_replacement = SELECT TOP 1 CONCAT('Region = ', RegionName) FROM Regions WHERE #condition LIKE CONCAT('%Region = ', Region, '%')
SET #ret = REPLACE(#condition, #string_pattern, #string_replacement)
... --and so on for each lookup
RETURN #ret
END
Word of warning. Above code was written from top of my head - might need some work. Also I wouldn't expect great performance.
