SQL stands for Structured Query Language. It is used to communicate with a database. With SQL, we can insert data, select data, update data, delete data, and create or modify database tables. It is used in database systems like Oracle, MySQL, and SQL Server.

A PL/SQL function error like PLS-00302 usually happens when a column, variable, or component is not declared properly. It may occur if the column name is wrong, the variable is not defined, or there is a mismatch in spelling or case. Checking the table structure and variable declarations can fix this problem.
