ORACLE SQL/PLSQL Online Training Course Content

Duration:3-4 Weeks

PL/SQL Stands for Procedural Language extension of SQL. PL/SQL is a combination of sql along with the procedural features of Programming languages.With PL/SQL, You can use SQL Statements to Manipulate ORACLE data and flow of Control Statements to process the data. By using of these we can create Data,update data and retrieve the data.
