BeastMode: Field contains lower case

swagner

Working on a exception report where item descriptions in our item file contain a lower case character.

 

Logic would work like this:

 

case

when `Description` LIKE '%[lower_case]%' then 'Yes'

else 'No'

end

 

Thanks!

@swagner What if you did this?

case
when `Description` = UPPER(`Description`) then 'All upper'
else 'Contains lowercase'
end

If your descriptions come in as all uppercase then it should match on the first when statement. Otherwise it wouldn't match because your description contains a lowercase letter and fall into the else condition.

I haven't tested, but hope it helps.

Hi @swagner ,

 

What is the issue here?

 

Thanks,

@Neeti what are you asking?

Neeti

@swagner , I cant see complete post, was just wondering is the lower case giving you any issue?

@Neeti the case statement I provided is simply an example of the logic I am attempting to build with a real beast mode.  This beast mode does not work as is.

I don't think this is doable with a regular expression in a Beast Mode however you can utilize a Magic ETL data flow with a replace text tile and a regex to remove any non-lowercase characters and then check if the value is NULL or not to determine if it doesn't or does have lowercase characters in it.

 

Another option is to utilize a MySQL dataflow instead:

select `holidayDescr`
, case when `holidayDescr` REGEXP '[a-z]' then 'Y' else 'N' end as has_lowercase
from `calendar_dates`

I suppose technically you could do a really long case statement based on each letter in the alphabet.

 

case when `Description` like '%a%' OR
`Description` like '%b%' OR
`Description` like '%c%' OR
`Description` like '%d%' OR
`Description` like '%e%' OR
`Description` like '%f%' OR
`Description` like '%g%' OR
`Description` like '%h%' OR
`Description` like '%i%' OR
`Description` like '%j%' OR
`Description` like '%k%' OR
`Description` like '%l%' OR
`Description` like '%m%' OR
`Description` like '%n%' OR
`Description` like '%o%' OR
`Description` like '%p%' OR
`Description` like '%q%' OR
`Description` like '%r%' OR
`Description` like '%s%' OR
`Description` like '%t%' OR
`Description` like '%u%' OR
`Description` like '%v%' OR
`Description` like '%w%' OR
`Description` like '%x%' OR
`Description` like '%y%' OR
`Description` like '%z%' THEN 'Y' ELSE 'N' END

Of course I overthink the whole thing. @MarkSnodgrass has a much cleaner solution.
