Here is a short T-SQL script for finding all columns in a database matching a given search string:
SELECT t.name AS table_name,
SCHEMA_NAME(schema_id) AS schema_name,
c.name AS column_name
FROM sys.tables AS t
INNER JOIN sys.columns c ON t.OBJECT_ID = c.OBJECT_ID
WHERE c.name LIKE '%Supervisor%'
ORDER BY schema_name, table_name;
