Prepared Statements in PostgreSQL
This PostgreSQL tutorial will walk you through one of the things you need to know in the PostgreSQL space: this PostgreSQL tutorial will walk you through PostgreSQL prepared statements and showcase how to create and execute them.
You don't need to go to a PostgreSQL conference to learn that PostgreSQL supports prepared statements in the sense that it allows you to generate SQL queries once and re-use them with different inputs.
In Postgres, prepared statements are scoped per-session and they also last for the duration of the session. PostgreSQL prepared statements can be created using PREPARE, then executed using the EXECUTE clause.
Use PostgreSQL prepared statements once you need to perform the same task over and over again during long-running sessions.

Here's how to prepare a PostgreSQL prepared statement (in this postgresql tutorial we name our PostgreSQL prepared statement "custom_task"):
PREPARE custom_task AS
INSERT INTO data_table (task_title, task_due, iscomplete)
VALUES ($1, $2, $3);
Here's how to execute a PostgreSQL prepared statement with the name of "custom_task":
EXECUTE custom_task ('First Task', '2024-06-05', false);
Adjust as necessary.
