How to get Option Set Description field in MSCRM - sql-server

Question

I've tried to find where Option Set descriptions are stored in CRM's database. After research on the internet I've found that Option Set data is stored in the StringMap SQL table but this table doesn't contain description Field I want.
Does anyone know where Option Set descriptions are stored stored in CRM's SQL database? Below is a screenshot highlighting the field value I'm looking for:

Answer 1

Try this:
SELECT Label FROM [LocalizedLabelView] llv
join [AttributePicklistValueView] apvv on llv.ObjectId = apvv.AttributePicklistValueId
join [OptionSetView] osw on apvv.OptionSetId = osw.OptionSetId
join [AttributeView] aw on osw.OptionSetId = aw.OptionSetId
where aw.Name = 'fieldname' and llv.ObjectColumnName = 'Description'
This works for both global and non-global option sets, you just have to put as fieldname the name of the attribute on the entity (not a name of global option set). Of course to handle only global option sets you will not need the last join, simply do osw.Name = 'globaloptionsetname'

Answer 2

This seems to work:
SELECT DISTINCT l.Label
FROM MetadataSchema.LocalizedLabel l
LEFT JOIN MetadataSchema.AttributePicklistValue ap ON l.ObjectId = ap.AttributePicklistValueId
LEFT JOIN MetadataSchema.OptionSet os ON os.OptionSetId = ap.OptionSetId
WHERE l.ObjectColumnName = 'Description' AND os.Name = '<OPTIONSET_NAME>' AND ap.Value = <OPTIONSET_VALUE>
There are two parameters in the above script that you need to modify:
<OPTIONSET_NAME> must be replaced with the schema name of your optionset and prefixed with the entity's schema name. For example, if your optionset is called new_businessTypes and it's on the account entity, then <OPTIONSET_NAME> would be replaced with 'account_new_businesstypes'.
<OPTIONSET_VALUE> must be replaced with the integer value of the option you're looking for. In your example screenshot, that value is 2.
