If you need to query your sql server's database to find out where a specific column is present into a table's schema, you can lauch this query against your database.

USE YOUR_DATA_BASE_NAME
GO
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 '%YOUR_Column_NAME%'
ORDER BY schema_name, table_name;
