What are SQL and plsql | Welcome to this article. Here, we will discuss about SQL and PLSQL. Imagine handling terabytes worth of data generated every single hour of every single day. This pause is a challenge even to the most powerful query tools and languages out there. And in this article, we are gonna compare procedure language SQL with the normal SQL.
So, here is the agenda for today’s article. We will take out the introduction of SQL and after this, we will check out everything there is to know about plsql such as what is plsql and much more. And after this, we will make the comparison between plsql and SQL to see where it stands?
And guys, if you have any queries make sure to hand out the comment section below and do let us know we will happy to out there.
So coming to the first item is an introduction to plsql. Well, what is plsql?
What is plsql?
Well, basically the PL in the part of SQL actually stands for the procedural language but then what we mean by them is exactly what we gonna check out.
So plsql is nothing but a procedural relational database language which actually developed by oracle corporation in 1990. So again plsql stands for procedural language and SQL stands for the structured query language.
By procedural language what we actually mean is that it allows the execution of a singular block of code at any point of time basically in hancing a powerful SQL language at the same time. So the block of code that you might be wondering what plsql actually comprised of. Well, it comes with many things and everything from procedures, functions, loops, variables, triggers and much more are the items in the block of code of a plsql block.
Then coming to the application of plsql, basically, plsql is used to build d web application, and maintain and work with server pages at the same time and it can do all of this very efficiently. But you can not use object-oriented techniques such as data abstraction, data hiding, and data encapsulation as well. Because we go about using a procedural language along with SQL. And this brings to us a quick introduction to SQL. So this is all about what is plsql.
What is SQL?
SQL is the structured query language. And it is the number one language that is used to deal with all the relational databases that are out there today. So basically SQL is used to perform the various operation that deals with the data stored in a database.
It involves the creation, operations such as reading, updating, deletion, and much more.
So what do you mean by relational database? So basically a relational database is nothing but a simple type of database that actually stores and provides access to data. But the difference here is what relation comes in. When we actually relate the data from one to another, this is done by making use of the point called keys and then you know primary keys, candidate keys, secondary keys, and much more which actually interlink the data form one table in the database to another table in the database and hence the name relational database.
Well, here is some relational database example, so we have mysql, Oracle, SQL Server, Sybase olise, and many other multiple players in the field of SQL. Again there is not much difference between each of these but there are certain time flavor changes when it comes to thinking such as appropriate syntaxes. So this is all about what is SQL.
Comparison between plsql and SQL
First, we look at the meaning. So, plsql helps execute one single block of code which consists of a procedural language and this is actually done in a very sequential way as the name suggests.
But when we talk about SQL, SQL actually involves the s execution of queries or let’s say even commands for that matter. Well, at any given point in time pretty much talk to the database, work with the database.
And when we talk about abbreviation, again plsql stands for procedural language as an extension of SQL. And SQL is generally known as a structure query language
When comes to the nest point that is purpose plsql and SQL. Well, basically plsql is concerned with the creation of the application. So why do we need this application? So, this application is mainly used to deal with all the data that is acquired by SQL. Well, SQL is again concerned with acquiring all of this data. So after acquiring data, they have to be stored in a database and let a walk on and that is where SQL comes into the picture. Again plsql is basically used to create all the applications by making use of all the data that is stored and manipulated by SQL.
Coming to the knowledge, plsql supports blocks of code again as mentioned procedures, functions, variables, packages, and much more.in the code block.
Conclusion:
In this article. We have covered the topics such as what is SQL and what is plsql and the comparison between SQL and plsql.
