What is the difference between sql and mysql and plsql.
PL/SQL (Procedure Language/Structured Query Language) is a database language used with Oracle Database. As SQL is a one line command system, in some situations it is not sufficient to process data for some batch processing systems. So PL/SQL is developed with the help of which batch processing can be performed and it is an extension using SQL.
MySQL is a database like Oracle and SQL Server that uses SQL language. It is a Open Source Software i.e., you can procure it freely. As the Oracle and SQL Server are costly, for simple web applications, one can make use of MySQL because it is free and has almost the basic features required for a database management system.
