I typically run queries like:
SELECT s.name, t.name, c.name
FROM sys.columns c
JOIN sys.tables t ON c.object_id = t.object_id
JOIN sys.schemas s ON t.schema_id = s.schema_id
WHERE c.name LIKE '%mob%'
Of course this assumes that the column naming is "reasonable". For a larger database with many tables, this can be a bit of needle-in-a-haystack thing.
Note: because you can add up to five tags in a post, doesn't mean that you have to. I took the liberty to remove two tags that were entirely irrelevant.
