This method is also used for SQL statements. So when your condition or action type is SQL Statement, you can specify the page item with a colon, as demonstrated in the above example. Getting Item Value using V() Function in Oracle Apex. You can use V() function to get the page item value in PL/SQL code. Check the below example Variable Declaration in PL/SQL PL/SQL variables must be declared in the declaration section or in a package as a global variable. When you declare a variable, PL/SQL allocates memory for the variable's value and the storage location is identified by the variable name. The syntax for declaring a variable is â In PL/SQL, a variable is named storage location that stores a value of a particular data type. The value of the variable changes through the program. Before using a variable, you must declare it in the declaration section of a block

The PL/SQL Function is very similar to PL/SQL Procedure. The main difference between procedure and a function is, a function must always return a value, and on the other hand a procedure may or may not return a value. Except this, all the other things of PL/SQL procedure are true for PL/SQL function too. Syntax to create a function Introducing to PL/SQL function PL/SQL function is a named block that returns a value. A PL/SQL function is also known as a subroutine or a subprogram. To create a PL/SQL function, you use the following syntax In Oracle, each value or constant is assigned with a data type. Basically, it defines how the data is stored, handled and treated by Oracle during the data storage and processing. The main difference between PL/SQL and SQL data types is, SQL data type are limited to table column while the PL/SQL data types are used in the PL/SQL blocks The PL/SQL programming language provides a data structure called the VARRAY, which can store a fixed-size sequential collection of elements of the same type. A varray is used to store an ordered collection of data, however it is often better to think of an array as a collection of variables of the same type
The above PL/SQL code will get the employee's first name and last name against the employee number being entered in the Page Item P12_EMPNO. It will return the employee name and the effected Page Item is P12_EMPLOYEE_NAME. 2. Oracle Apex Dynamic Action Execute PL/SQL Code to Set Page Item Value The keyword 'SET' instruct that PL/SQL engine to update the value of the column with the value given. 'WHERE' clause is optional. If this clause is not given, then the value of the mentioned column in the entire table will be updated. Data Deletion. Data deletion means to delete one full record from the database table. The 'DELETE' command is used for this purpose. Syntax: BEGIN DELETE FROM. ORA-06512 - PL/SQL: numeric or value error%s Apologies... this is related to a previous question answered earlier today, but I did not know how to ask a 'follow up' question...I've written the code below to generate an email report on users in an instance which have not been logged into in the last 15 days.I tried to add a variabl Description. The Oracle/PLSQL NTH_VALUE function returns the nth value in an ordered set of values from an analytic window. It is similar to the FIRST_VALUE and LAST_VALUE functions except the NTH_VALUE lets you find a specific position in the analytic window such as 2nd, 3rd, or 4th value Use datatypes in your PL/SQL code that correspond to, or are at least compatible with, the underlying database tables. Think twice, for example, before reading a TIMESTAMP value from a table into a DATE variable, because you might lose information (in this case, the fractional seconds and perhaps the time zone). Getting the current date and time

In PL/SQL, we can pass parameters to procedures and functions in three ways. 1) IN type parameter: These types of parameters are used to send values to stored procedures. 2) OUT type parameter: These types of parameters are used to get values from stored procedures. This is similar to a return type in functions. 3) IN OUT parameter. Bind values from PL/SQL-only datatypes to SQL statements. Return result sets from SQL queries implicitly, easing the migration path from languages such as Transact-SQL to Oracle PL/SQL.

How to declare variable in PL/SQL. You must declare the PL/SQL variable in the declaration section or in a package as a global variable. After the declaration, PL/SQL allocates memory for the variable's value and the storage location is identified by the variable name Problem You want to create a PL/SQL procedure that accepts several parameters. However, some of those parameters should be made optional and contain default values. Solution You can allow the procedure caller to omit the parameters if default values are declared for the variables within the procedure. The following example shows a procedure declaration that contains default values What Is PL/SQL Ref Cursors In Oracle Database? When it comes to performance, PL/SQL Ref Cursors in Oracle have always proven themselves superior to static cursors. Because of the ability of a single ref cursor to get associated with multiple SELECT statements in a single PL/SQL block. In addition, this reduces the need for writing separate.
. Below is an example: Assign Value to a Variable from SELECT Statement in PL/SQL Example In the following PL/SQL program, it will get the employee name into variable V_ENAME from the EMP table for employee number 7369 While procedure and function are often used as synonyms, in PL/SQL they are quite different and should be used accordingly. If you need a program that changes something (delete content, create new structures and so on), it should be a procedure. However, if the main purpose is getting a return value (selecting data, getting results for calculations etc), it should be a function. Functions.
The PL/SQL CASE statement allows you to execute a sequence of statements based on a selector. A selector can be anything such as variable, function, or expression that the CASE statement evaluates to a Boolean value. You can use almost any PL/SQL data types as a selector except BLOB, BFILE and composite types . means that PL/SQL engine cannot convert a character-typed string into a number or a subset of arithmetic for overall evaluation
Performs an XQuery against the XML and returns a value of SQL type. This method returns a scalar value. You typically use this method to extract a value from an XML instance stored in an xml type column, parameter, or variable.

lt_tab(1).some_field := some_value; for all pl/sql tables involved in those 10 lines. That is, just write over everything into the first element. If this eliminates the slowdown, one could even try to write into some _high_ element: lt_tab(999999999).some_field := some_value; just to see if it makes any difference (very much doubt it). One question for Greg assuming the code is in a package. In several ways: Write a procedure: If you don't need the function in SQL, a procedure might do the trick just as well. Here's an example: [code]CREATE PROCEDURE a. Furthermore, the value of SQL%ROWCOUNT attribute is unrelated to the state of a transaction. Therefore: When a transaction rolls back to a savepoint, the value of SQL%ROWCOUNT is not restored to the value it had before the save point. When an autonomous transaction ends, SQL%ROWCOUNT is not restored to the original value in the parent transaction. Here's the code for the quiz - see how you do.

Q #30) What do you understand by PL/SQL Records? Answer: A PL/SQL records can be referred as a collection of values or say, a group of multiple pieces of information, each of which is of simpler types and can be related to one another as fields. There are three types of records supported in PL/SQL: Table based records; Programmer based record The anonymous PL/SQL blocks also allow me to handle the transaction commit or rollback in the block rather than putting that code in the Oracle stored procedure or function. Since PL/SQL has a rich set of capabilities, we felt it better to leverage it as much as possible and just call it from the SSIS packages
Whenever PL/SQL block having procedural statements and also those statements find to convert string type to number type then oracle servers returns an error: ora-6502:numeric or value error: character to a number conversion erro In PL/SQL code groups of commands are arranged within a block.

Given two strings and the task is to concatenate them and store it in another string. Examples: Input: str1 = ' RAMESH', str2 = 'SURESH' Output: RAMESH SURESH Input: str1 = ' Ramesh is a. The Oracle Database supports a concept of a null value, which means, essentially, that it has no value.The idea of having nulls in a relational database is controversial, but Oracle Database supports them and you need to know how they can impact your work in PL/SQL. First, and most important, remember that: Null is never equal to anything else, including null PL/SQL function to return more than one value. Julian Forum Advisor. Messages: 68 Likes Received: 1 Trophy Points: 90. hello, is it possible to return more than one value from a PL/SQL function. for example, in my function I have a IF block from where I want to return two values: Code (Text):.. IF sales_cur%NOTFOUND THEN CLOSE sales_cur; RETURN NULL; ELSE CLOSE sales_cur; RETURN [B]return. The value of the SQL%ROWCOUNT attribute refers to the most recently executed SQL statement from PL/SQL. To save an attribute value for later use, assign it to a local variable immediately. The SQL%ROWCOUNT attribute is not related to the state of a transaction. When a rollback to a savepoint is performed, the value of SQL%ROWCOUNT is not restored to the old value before the savepoint was taken.
