Writing a procedure in oracle pl/sql

Ever since we created our first stored packaged function, we have had to suffer a continual trade-off between the encapsulation of business rules and optimal performance. We have usually paid a performance penalty for good programming practices in one or more of the following ways:

If the dynamic SQL statement invokes a subprogram, ensure that: The subprogram is either created at schema level or declared and defined in a package specification. Every bind variable that corresponds to a placeholder for a subprogram parameter has the same parameter mode as that subprogram parameter and a data type that is compatible with that of the subprogram parameter.

No bind variable is the reserved word NULL. To work around this restriction, use an uninitialized variable where you want to use NULL, as in Example No bind variable has a data type that SQL does not support such as associative array indexed by string. If the data type is a collection or record type, then it must be declared in a package specification.

Bind variables can be evaluated in any order. If a program determines order of evaluation, then at the point where the program does so, its behavior is undefined.

Collection types are not SQL data types. In each example, the collection type is declared in a package specification, and the subprogram is declared in the package specification and defined in the package body.

Specify mode for first parameter. Modes of other parameters are correct by default. The record type is declared in a package specification, and the subprogram is declared in the package specification and defined in the package body.

Use the FETCH statement to retrieve result set rows one at a time, several at a time, or all at once. The dynamic SQL statement can query a collection if the collection meets the criteria in " Querying a Collection ".A PL/SQL subprogram is a named PL/SQL block that can be invoked repeatedly.

If the subprogram has parameters, their values can differ for each invocation. A subprogram is either a procedure or a function. Typically, you use a procedure to perform an action and a function to compute and return a value.

Java Database Connectivity (JDBC) is a method of Java calling SQL and PL/SQL. The DML operations of SELECT, INSERT, UPDATE, and DELETE as well as calling PL/SQL procedures and returning of resultsets can be done using JDBC.

This is my SQL Server Stored Procedure which is below: CREATE PROCEDURE passenger_details AS BEGIN SELECT Full_Name, Age, Nationality, Category, Airline_Name, Class_Type FROM Passenger, Ticket, Ai. A PL/SQL subprogram is a named PL/SQL block that can be invoked repeatedly.
