Recently wanted to get logical names of 25 columns at one go. Business analyst provided us with display names. One colleague of mine quickly told me about a workaround from database to read all at one go
Select ll.Label, Attr.LogicalName From LocalizedLabelAsIfPublishedView ll
INNER JOIN Attribute attr
ON ll.ObjectId = attr.AttributeId
INNER JOIN EntityView ev ON ev.EntityId = attr.EntityId
WHERE ev.ObjectTypeCode = EntityTypeCode and ll.ObjectColumnName in (‘DisplayName1’,
‘DisplayName2’)
