PostgreSQL – How to Get the DDL of a View
To retrieve the Data Definition Language (DDL) script for a specific view in PostgreSQL, you can use the pg_get_viewdef function. This function allows you to obtain the SQL statement that defines the view. Here’s how you can use it:
SELECT pg_get_viewdef('view_name', true);Replace 'view_name' with the name of the view for which you want to retrieve the DDL script.
Here’s an example:
Consider a view named “my_view” that you want to get the DDL script for. You can use the following SQL query:
SELECT pg_get_viewdef('my_view', true);This query will return the DDL script that was used to create the “my_view” view. Setting the second argument to true (pg_get_viewdef('my_view', true)) formats the output to be more human-readable.
Keep in mind that the pg_get_viewdef function retrieves the definition of the view as it was created. If the view has been modified after its creation, this script may not reflect the current state of the view.
