pl sql programs

Sometimes, we may find that some functions are difficult to complete through PL/SQL, while programming through C/C ++ is much easier. Therefore,OracleProvides the ability to directly call external functions (including C functions or Java methods) in PL/SQL programs, thus ext

Stored Procedures and functions A subroutine stored in a database for calls by all user programs is called a stored procedure and a stored function. Create a stored procedure: UseCREATEPROCEDURECommand to create a stored procedure and a stored function. Syntax: Create[OrReplace]PROCEDUREProcess name (parameter list) AS PLSQL subprogram body; Note: stored procedures are generally used in highly secure systems. Example 1: increase the salary

. These datatypes are not supported ed in this article. In practice, you may encounter other numeric types, such as float, integer, and decimal. These are subtypes of the four core numeric types in the preceding list. Now let's take a closer look at number and pls_integer. The number datatype. the number data-type is by far the most common numeric datatype you'll encounter in the world of Oracle and PL/SQL

1) classification of Sets Oracle supports three types of collections: Associative array (Index-by table) Nested table) Variable-length array (VARRAY) One of their differences is that the Nested table and VARRY can be used either in PL/SQL or directly in the database, but the Associative array doesn't work, that is, associative array cannot be created separately using the create type statement. It can only b
