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  

I get some information on the columns of a particular table but the default value of the columns is missing, How can I get it?

Answer 1

You can find the stored definition with the below (remember to adjust the column and table name to find to be ones relevant to your environment!)

SELECT object_definition(default_object_id) AS definition FROM   sys.columns WHERE  name      ='colname' AND    object_id = object_id('dbo.tablename') 

Answer 2

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;
