Sum of the first and last digit of a number in PL/SQL
In this problem, we are given a number n. Our task is to create a program to find the sum of the first and last digit of a number in PL/SQL.First, let’s brush-up about PL/SQL, PL/SQL is a combination of SQL along with the procedural features of programming languages.Let’s take an example to understand the problem, Input − n = 31415Output − 8Explanation − first digit = 3 , last digit = 5. Sum = 8To, solve this problem, we will extract the first and last digit to number n. And the print their sum.The first and last digits are ...
Read MoreCount no. of characters and words in a string in PL/SQL
We are given a string of any length and the task is to calculate the count of characters and words in a string using PL/SQL.PL/SQL is a combination of SQL along with the procedural features of programming languages.It was developed by Oracle Corporation in the early 90's to enhance the capabilities of SQL. PL/SQL is one of three key programming languages embedded in the Oracle Database, along with SQL itself and Java.In PL/SQL block, we have DECLARE block which is used to declare the variables used in programming and we have BEGIN block where we write the logic for the ...
Read MoreConvert distance from km to meters and centimeters in PL/SQL
The task is to convert the distance from kilometers to meters and centimeters in PL/SQL.PL/SQL is the extension of SQL which combines the Data manipulation of SQL with the working of procedural language.According to the problem we should have distance in kilometers whose value we have to convert in meters and centimeters.As per the conversion rule −1km = 1000 meters1km = 100000 centimetersAccording to this conversion rule we want the distance to be converted by a logic in PL/SQL.ExampleInput: kilometer = 10 Output: meter = 10000 Centimeter = 1000000 Input: kilometer = 9 Output: meter = 9000 Centimeter ...
Read MoreDatabase Wars: MSSQL Server, Oracle PL/SQL and MySQL

Read MoreCheck if a number is Palindrome in PL/SQLs
In this section we will see how to check whether a number is Palindrome or not using the PL/SQL. In PL/SQL code, some group of commands are arranged within a block of related declaration of statements.A number is palindrome if the number, and the reverse of that number are same. Suppose a number 12321, this is palindrome, but 12345 is not a palindrome.ExampleDECLARE n number; m number; temp number:=0; rem number; BEGIN n :=12321; m :=n; while n>0 loop rem := mod(n, 10); temp := (temp*10)+rem; ...
Read MoreCheck if a given year is leap year in PL/SQL
Here we will see how to check given year is leap year or not, using PL/SQL. In PL/SQL code, some group of commands are arranged within a block of related declaration of statements.The leap year checking algorithm is like below.AlgorithmisLeapYear(year): begin if year is divisible by 4 and not divisible by 100, then it is leap year else if the number is divisible by 400, then it is leap year else it is not leap year endExampleDECLARE year NUMBER := 2012; BEGIN IF MOD(year, 4)=0 ...

PL/SQL stands for “Procedural Language extension to SQL” . It is the mixture of SQL and Procedural features provided by programming language. It was developed by Oracle Corporation in the late 1980s as procedural extension language for SQL and the Oracle relational database.PL/SQL programs consists of blocks that can be nested and a block structure look likes this −DECLARE -- it contains declaration statements BEGIN -- It contains executable statements EXCEPTIONS -- It contains exception handling statements END;ExampleIn PL/SQL single-line comments begin with double hyphen(--) and Multi-line comments begin with a slash-asterisk ( /* ) and end ...
Read MoreCan’t create a Dictionary Object: View by adding two db tables
When you create a view, it is created on top of multiple database tables using an inner join. Note that basis table of database views should be transparent tables.To create a view on 2 tables, you have to enter the primary table you want to maintain and place the cursor in that field and click on the button below the list of tables and select the other table to add the view. If you are not getting this option, it means Relationship is wrong.To know more about database Views: https://help.sap.com/doc/abapdocu_750_index_htm/7.50/en-US/abenddic_database_views.htm
Read MoreHow to use SUM function for NUMC type field?\\n
NUMC is numeric text. As this is text, SUM function cannot be implemented as it is of type varchar in the database.There is no simple solution to do it. The one method is to copy the data to internal tables, convert the NUMC data into DEC by looping through all the rows, SUM and GROUP them and then convert back the DEC values back to NUMC values.
