SQL Server: Find out default value of a column with a query

Question

How can I find out the default value of a column in a table using a SQL query?

By using this stored procedure:

sp_columns @tablename 

Answer 1

I use INFORMATION_SCHEMA table like this:

SELECT 
    TABLE_SCHEMA, TABLE_NAME, COLUMN_NAME, COLUMN_DEFAULT
FROM
    INFORMATION_SCHEMA.COLUMNS
WHERE
  TABLE_SCHEMA = @SchemaName 
  AND TABLE_NAME = @TableName
  AND COLUMN_NAME = @ColumnName;
