Data Type Mapping
Ensure proper mapping of data types between Oracle and MySQL. For instance:
NUMBER in Oracle corresponds to INT or DECIMAL in MySQL.
VARCHAR2 in Oracle maps to VARCHAR in MySQL.
Test the Migration
Apply the translated MySQL code to your MySQL database. Test the functionality to ensure that the migrated code behaves as expected.
Example Output:
After migrating the PL/SQL function to MySQL and inserting test data:
MySQL Query:
SELECT get_employee_name(101) AS emp_name;
How to migrate an PL/SQL to MySQL
Migrating PL/SQL (Procedural Language/Structured Query Language) code to MySQL involves translating Oracle’s PL/SQL syntax and features into MySQL’s SQL language.
This process requires careful consideration of differences in syntax, data types, and supported features between the two database systems. Let’s go through the steps of migrating PL/SQL code to MySQL, along with examples.
