To add a column with a default value to an existing table in SQL Server, you can use the ALTER TABLE statement along with the ADD clause. Here’s the general syntax:
ALTER TABLE table_name
ADD column_name data_type DEFAULT default_value;
For example, suppose you have a table named MyTable and you want to add a new column named NewColumn with a default value of 0:
ALTER TABLE MyTable
ADD NewColumn INT DEFAULT 0;
This SQL statement adds a new column named NewColumn to the MyTable table with the INT data type and a default value of 0.
Remember to replace table_name, column_name, data_type, and default_value with the appropriate values for your specific scenario.
