Longueur du caractère SQL Server 2005

Question

J'ai créé une requête (voir ci-dessous) mais, au lieu d'avoir un retour de "supérieur à 20 ou 30", je veux que ma requête affiche réellement le nombre (par exemple 31, 35, 50, etc.). Je n'arrive pas à comprendre comment le faire. Merci pour l'aide.

select 
cc_units_of_measure.description as UOM_Description, 
case when LEN(cc_units_of_measure.description) < 20 then 'OK' 
else 'Greater than 20' 
end as Results_UOM_description, 
cc_units_of_measure.company_abbreviation as UOM_Company_Abbreviation, 
case when LEN(cc_units_of_measure.company_abbreviation) < 20 then 'OK' 
else 'Greater than 20' 
end as Results_UOM_company_abbreviation, 
cc_frequencies.description as Freq_Description, 
case when LEN(cc_frequencies.description) < 30 then 'OK' 
else 'Greater than 30' 
end as Results_Frequency_description 
from cc_units_of_measure, cc_frequencies 

Answer 1

Si vous changez la partie else des déclarations de cas pour retourner la longueur que vous obtiendrez la valeur que vous cherchez comme ceci:

SELECT cc_units_of_measure.description AS UOM_Description , 
     CASE WHEN LEN(cc_units_of_measure.description) < 20 THEN 'OK' 
      ELSE LEN(cc_units_of_measure.description) 
     END AS Results_UOM_description , 
     cc_units_of_measure.company_abbreviation AS UOM_Company_Abbreviation , 
     CASE WHEN LEN(cc_units_of_measure.company_abbreviation) < 20 THEN 'OK' 
      ELSE LEN(cc_units_of_measure.company_abbreviation) 
     END AS Results_UOM_company_abbreviation , 
     cc_frequencies.description AS Freq_Description , 
     CASE WHEN LEN(cc_frequencies.description) < 30 THEN 'OK' 
      ELSE LEN(cc_frequencies.description) 
     END AS Results_Frequency_description 
FROM cc_units_of_measure , 
     cc_frequencies
