If you need to locate a field in a large database and you don’t know what table the filed is or not really sure of the exact spelling of the field, you can use this simple query to search for fields names in a database.

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_Field_Name%'
ORDER BY schema_name, table_name
