How to Add Default Value in Oracle?<\/p>\n

When working with databases, particularly Oracle, it is common to come across scenarios where you need to assign default values to columns. A default value allows you to set a predetermined value in a column if no specific value is specified during the data insertion. In Oracle, adding default values is a straightforward process. Let’s explore how it can be done.<\/p>\n

To add a default value to a column in Oracle, you can use the ALTER TABLE statement combined with the DEFAULT keyword. Here’s the basic syntax:
\n“`
\nALTER TABLE table_name
\nMODIFY (column_name DEFAULT default_value);
\n“`<\/p>\n

Replace “table_name” with the name of the table containing the column you want to add a default value to. Similarly, substitute “column_name” with the actual name of the column. Finally, specify “default_value” with the value you want to set as the default.<\/p>\n

Let’s assume we have a table called “employees” with a column named “salary” that we want to set a default value of 5000. We can achieve this by executing the following statement:
\n“`
\nALTER TABLE employees
\nMODIFY (salary DEFAULT 5000);
\n“`<\/p>\n

Once this operation is complete, any new row inserted into the “employees” table without explicitly setting a value for the “salary” column will automatically have a default value of 5000.<\/p>\n
