You’ll have to sign in to your Oracle account in the event that you don’t have a single tick on making a record and set one up.

Prophet SQL Developer versus Oracle SQL Developer Data Modeler:

• Two separate items however

 

• There is a variant of Data Modeler that incorporates into SQL Developer

 

• To see the information structures and articles in the data set and to keep up the information SQL Developer

 

• To plan the information base and keep up the information structures

Information Modeler

• To plan the information engineering Data Modeler

Highlights of Oracle SQL Developer:

Article Browser:

SQL Developer permits you to tour the contents of your database. We can use the connection tree for this purpose. Extend the table junction will show you the list for the connected user.

SQL Worksheet:

•  The use of the SQL query builder found in the SQL developer product. The data used in this example imported from an excel file. In worksheet the first allows you to enter script files in standard SQL format. The second query builder allows you to import items and use a graphical interface.

 

•  We will drag the car to the table into the query builder window now. You may select specific data items within the table. which you will notice appear in the separate window below to run an SQL query in this mode. select the run statement which is the green arrow. which appears at the top of the toolbar?

 

•  Your results will appear in the query result to see the same query in an SQL script file click on the worksheet tab. which will show you the same query in a text format? You may use the query builder panels to create complex SQL queries in this example? I have set up a query.

 

• Where I’m looking for the average model year of a particular car the Fiesta to access. For the Associated SQL statements click on them here. You can see the same query in a script file notice that the query builder provides for many options.

 

• Here you can select any of the following including count max min standard deviation. You may also set up your aliases for column headers sort types primary and secondary. It allows you to associate items with particular sets in this example.

 

•  I am seeking the greatest or oldest year for each car grouped by car make here. I’ve laid out criteria for that query that same criterion as set forth in the script file. When I run it you will notice that the results. I have results. I want it and I can also change to allow for sorting. You sort orders a good use of the query builder. The ability to set up a script file and then use that script file to change your queries.

 

•  I will use the largest query. I Illustrated and will now change that to provide for the least for those same types. now we have a similar result. it shows the lowest year for each of the cars makes I can also provide for an average year for each of these.

 

•  You see the average year based on car make. so this provides a quick way of setting up your scripts. and then allows you to go in and change as appropriate in conclusion. the query builder worksheet allows you to jumpstart. your query creations and also allows you to access many of the Oracle functions. in a quick and efficient manner.

 

Data Grids:

• We’re going to talk about everything. You ever wanted to know about the data grids and Oracle sequel developer. When I say data grids. I’m talking about the presentation of query results. When you run a query using this button which maps to control-enter.

 

• If you’re going to browse the contents of a table here on the data tab this is a grid. You’ll see these grids all over the place in the tool. And so a lot of what I’m showing you today applies for. wherever these grids present. I’ll be showing you the data grid and a sequel worksheet.

 

• So the first thing I want to take a look at is controlling. How do these grids look? So we have black text on a white background. We have the default font on windows at least. So let’s go into the preferences. You’ll see on the database category at the very bottom there’s a worksheet page.

 

• We’re going to make two changes. so I so going to make one change here. we are going to enable this and then we’re also going to go to the code editor page to fonts. We’re going to choose a font that we’d like let’s say joy seems mom. I want you guys to be able to see the data.

 

• I’m going to go up on a larger font by the way you can make this text here anything that you want. So if you’re having problems getting certain Unicode characters to display. Your favorite emoji or a character from a Chinese character set or Arabic. You type them in here and you’ll see how they print below right out of the box. So that’s good trouble with shooting technique.Procedure Editor:
• We took a look at named and anonymous PL sequel blocks. We said those are the two basic ways of creating PL sequel code. That you can run against your database. We said that named blocks can be either function. And took a look at some functions that are pretty easy to understand.

 

• They’re always going to return a value procedure that doesn’t return a value. You can call them without assigning them to a variable. but you can have parameters that go along with procedures. we saw that was true of functions also you have parameters that go along with procedures.

 

• Those parameters can be of three types. It’s two parameters and they can have three types. You can have in parameters you can have out parameters. You can have it out all right these are going to read these are going to be right and these are going to read right.

 

• So a procedure doesn’t have to return a value. You can specify parameters as being out parameters. Which will return the value back. whatever calls this particular procedure in outs are exactly. you know what they sound like also there are parameters.

Source Control:

• source control for Oracle enables easy database source control with SVN and TFS. The tool tracks the differences between the database. Your source control repository and notifies you when a change needs to check-in. you can then review the DDL before you source control.

 

• Your changes let’s take a closer look at how source control for Oracle works. Let’s say you’ve been working on the database source control for Oracle detects. the changes in the database and reminds you to check them into source control. You can go to those changes.

 

• Which you can review comparing the DDL for the objects in the database to what’s in source control. You can check in all the changes together or select individual objects. If objects are dependent on other objects. You prompted to check them in at the same time. Once you’ve made your selection and your log message. and that’s it you and your team can see a complete history of changes that have in showing.
• Why including revision numbers source control? The Oracle makes the process of checking changes into source control. As simple as clicking a button. the need for the complex solutions currently required to manage database version control.

Reports DBA Console:

• We’ll save the SQL worksheet and then we can invoke the worksheet. Now tell me this thing how good will it be if you can save the SQL query within your SQL Developer. Where you don’t need to open a SQL script file amazing right. How do we do it so first of all we need a query that we want to store inside the SQL Developer
• It makes their life easy because they can store as many reports as they want inside the SQL Developer. And click and see the data and that helps them to create great pl/SQL programs. This was the simplest introduction to the reports guys inside the SQL developer
  Now there are a lot of other types of reports. what I will do is for you guys? I’ll add some reading material below this video. So that you can go ahead and look at different other types of reports that you can create inside the SQL Developer

Unit Testing:

We are finding out about unit testing work processes. It has parts, making experiments and test suites, producing experiments. The test-driven improvement approach and code inclusion reports in unit testing.

• Database Utilities :
  it is a very fast utility. Its use for export-import data pumps data database backup. We can take a backup live sorry schema level and user-level data mem export-import mod. There are some mods full database backup schema level backup export-import and table. They were export-import and tablespace level export-import.

 

• We can also take an export-import transport table tablespace. From one platform to another platform. We can use the export-import command. And export-import utility data bump utility provided flexibility. It is a very fast export-import utility

 

Data Modeler:

• We are going to see how to create a data model using SQL Developer for an existing schema. We will be creating a data model using an existing schema. So first of all let me tell you that the data model can create with more than one schema.
• It depends on the need. I will tell you what is exactly the data model can use. We create into two-way well one is forward upon this backward. Which call reverse engineering. So what is that you create a data model without creating any physical database. You create a logical model.

 

• Your beautiful title creates all kinds of rules or kinds of constraints. And after creating the data model. you can generate one data definition language and the data definition language. you can create the database and suite on the tables and different objects. But here what we are going to see we are going to create one data model from an existing database. There is it existing schema with a couple of tables and

 

• We will be creating the data model using that it’s the same schema so for creating it. I will first show you the wizard okay in the wizard. How can we create a data model so go to file go to data modeler input and data dictionaries?
• What exactly the data actually? Those data dictionary actually fetches the existing data dictionary of the Oracle. From the Oracle database and whichever schema. You select it manipulates is data dictionary to create the data module. So let us click on the data dictionary so this is the list of connections.

 

• I have an existing collection so this connection is from for SQL Developer. So you have to select one of the connections. I ting office and next so what is happening. when you are selecting this collection and clicking next. It is connecting to the connection string. which provides to the office okay. when it is connecting. it’s getting a couple of users schemas or uses okay.
• This thing under this connection so sees here. we have a lot of connections. so what we are going to do yeah exactly going to use the office’s connection. Because this is the schema user. Because we have a lot of connected users. which has permission on this schema all our office like officer manager.

APEX Listener:

Oracle Application Express is a low-code development platform. It enables you to build scalable, secure enterprise apps. We can do work with world-class features, that can deploy anywhere.

 

Conclusion:

• Oracle SQL Developer knows as an enterprise database. it’s a program that’s designed to store a bunch of information or data. so database stores data. so data goes inside of the database. if that makes any sense well what’s data well think of data very.

 

• it’s nothing too specific. It can do anything that you need to store for later use. you can use it for business and other needs. so business will need to store data so they can analyze that data and make business decisions right
