If the dynamic SQL statement is a DML statement with a RETURNING INTO clause, put in-bind variables in the USING clause and out-bind variables in the RETURNING INTO clause.Dynamic SQL is a programming methodology for generating and running SQL statements at run time. It is useful when writing general-purpose and flexible programs like ad hoc query systems, when writing programs that must run database definition language (DDL) statements, or when you do not know at compile time the full text of a SQL statement or the number or data types of its input and output.


OPEN CURSOR: The dynamic SQL will execute in the same way as a cursor. So in order to execute the SQL statement, we must open the cursor. PARSE SQL: The next step is to parse the dynamic SQL. This process will just check the syntax and keep the query ready to execute.The second statement is an Execute Immediate statement of Dynamic SQL. Here you write the reserved phrase EXECUTE IMMEDIATE followed by the name of the variable where your block is stored. Followed by a semi colon at the end of the statement.
