How do I list or search all the column names in my database in the SQL server?

You can use following query to list all columns or search columns across tables in a database.

USE AdventureWorks 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 '%EmployeeID%' ORDER BY schema_name, table_name;
You can make use of information_schema views to list all objects in SQL Server 2005 or 2008 databases.
SELECT * FROM information_schema.tables SELECT * FROM information_schema.columns
