Placeholders are used to distinguish between parameter values used as criteria and those providing identifiers like column names. Placeholders help to avoid ambiguity in the code and make it more readable and easy to maintain. DDLs (Data Definition Language) are used to create database objects such as tables, views, and indexes. DMLs (Data Manipulation Language) are used to modify or retrieve data from database objects. Cursors are used to retrieve and manipulate a set of rows one at a time.
