How to Resolve Oracle SQL Parent Key Not Found (ORA-02291)
 
05:49
In this video, we’ll explain what the ORA-02291 “parent key not found” error is, see an example, and look at how to resolve it. This error usually happens when we try to insert data into a table. It looks like this: Error is: ORA-02291: integrity constraint (constraint_name) violated - parent key not found So what does this error mean? It means we’re trying to insert data into a child table, and there is no related record in the parent table. If a foreign key has been set up to enforce this relationship, there needs to be a parent to insert a child that refers to it. Watch the video to see an example of this error as well as how to resolve it. For more information on Oracle SQL, refer to the Database Star website here: https://www.databasestar.com/

8. Use LOG ERRORS to suppress SQL errors at the row level.
 
06:23
The impact of a non-query DML statement is usually "all or nothing". If my update statement identifies 100 rows to change, then either all 100 rows are changed or none are. And none might be the outcome if, say, an error occurs on just one of the rows (value too large to fit in column, NULL value for non-NULL column, etc.). But if you have a situation in which you would really like to "preserve" as many of those row-level changes as possible, you can add the LOG ERRORS clause to your DML statement. Then, if any row changes raise an error, that information is written to your error log table, and processing continues. IMPORTANT: if you use LOG ERRORS, you must must must check that error log table immediately after the DML statement completes. You should also enhance the default error log table.

Oracle SQL Tutorial 19 - ON DELETE (SET NULL and CASCADE)
 
05:59
Welcome everyone! Something you need to consider when you are creating foreign keys is what happens if you delete the parent? As a reminder, the parent is the row that has the value you are referencing in the row that has a foreign key. Why is this something important to consider? It's important because foreign keys need to protect us from two primary things, unacceptable INSERT statements, and unacceptable DELETE statements. Let's see what happens when we try to insert incorrect data into the table with the foreign key: INSERT INTO projects VALUES (1, 'Update website homepage', 'CalebCurry') The response tells us plainly that there is no such user in the users table. So this works correctly. Deleting data on the other hand works a bit differently because the database does not know what you want to do with the child row when you delete the parent from the parent table. By default, we will get an error message that prevents the parent from being deleted, but there are some other options. How do we configure this? This is where the ON DELETE statement comes in. We add the keywords ON DELETE right after the foreign key and then we can give it the option of CASCADE or SET NULL. CASCADE means that if we delete the parent, we are also going to delete the child. In our situation what that means is that if somebody creates a project in our project table and then that persons account gets deleted, all of the projects he owns will also be deleted. CASCADE: CREATE TABLE projects( project_id NUMBER, Project_name VARCHAR2(50 CHAR) UNIQUE, creator VARCHAR2(50 CHAR) NOT NULL, CONSTRAINT projects_pk PRIMARY KEY (project_id), CONSTRAINT projects_users_fk FOREIGN KEY (creator) REFERENCES users (username) ON DELETE CASCADE ) SET NULL will take the value in the child table and get rid of it. What you are left with is NULL. This means that we have an orphaned child. The first thought you might have is that it is a bad thing to have an orphaned child, but in databases that is not always so. In our application if we had it set to SET NULL, when a user account gets deleted the projects would remain in existence they would just lack a creator. This might be a good thing if you are concerned about the long term survival of a project, this might be the route you want to go. It ultimately depends on the application purpose. If you don't like CASCADE or SET NULL, you can leave the entire ON DELETE statement and just have Oracle throw an error when a parent is deleted. As for us, we are going to use ON DELETE CASCADE. We need to use this with extreme caution. If you are not careful, someday you will run a delete a row and that will cascade through you database deleting a bunch of stuff you didn't want to delete. Stuff happens, so make sure you back up your database every once in eternity. Now, in the last video we started with a database design that had three tables. We've only created two in this video. In the next video we are going to create the next one, which is a little special. Then we'll finish things up by adding some indexes. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Support me on Patreon! http://www.patreon.com/calebcurry Subscribe to my newsletter: http://bit.ly/JoinCCNewsletter Donate!: http://bit.ly/DonateCTVM2. ~~~~~~~~~~~~~~~Additional Links~~~~~~~~~~~~~~~ More content: http://CalebCurry.com Facebook: http://www.facebook.com/CalebTheVideoMaker Google+: https://plus.google.com/+CalebTheVideoMaker2 Twitter: http://twitter.com/calebCurry Amazing Web Hosting - http://bit.ly/ccbluehost (The best web hosting for a cheap price!)

Best Way to Write Basic SQL Queries
 
13:33
SQL Server Query writing strategies is something I have yet to find in any book. When enthusiastic SQL students do this, they experience a revelation. The number of errors drops significantly and the speed at writing complex queries increases immediately. Knowing how to narrow down what we are looking for amongst a vast list of choices helps immensely. Grabbing the right tables first and then the fields second is akin to grabbing the right menu before ordering an item from it. In fact, one student named Tim took this back to his team of SQL developers and they immediately implemented this process. We are all used to following steps. Most of the time, actions are sequential from top to bottom or left to right. Other times we complete things in phases. The two phases we are going to use in this exercise apply to joining tables. This is easy to implement as we only need remember to organize first and clean up second. When visiting a new restaurant, we will ask to see the menu, because we want to see all they have to offer. The odds are that we might be interested in half of the items, but only need a few dishes for our group at the table. Looking at the menu is like starting a query with a ‘SELECT *’ statement. Once we have looked at all the fields, we narrow our choice(s) to only the items we want at the time. Sometimes restaurants have multiple menus. My favorite restaurant has a kids’ menu, an adult menu, a gluten-free menu and a drink menu. These menus were each gathered at our table. Ultimately, in my head, a selection was narrowed to what was needed. Phase I: Organize. When building a new query from many tables, we often find ourselves wondering, “Where do I start?” First, lay the steps out by identifying which tables contain the essential data. Second, get all the table joins working with a basic ‘SELECT *’ statement. Third, add any basic filtering criteria. Phase II: Itemize. Once all joins and criteria, such as SELECT, FROM and WHERE are working, we are ready for Phase II. This entails going back and changing our ‘SELECT *’ to an itemized SELECT field list as the final step. Let’s explore how this two-phase process of Organize and then Itemize can be a big time-saver. We are going to use one of the challenges from the last lab. In Lab 3.2 (Outer Joins), Skill Check 2, we needed to get four fields from two different tables. If we were to list all four desired fields and test one table at time, we will get an error as seen on the right side of the figure below. In the figure below we write a SELECT statement and part of the FROM clause. When completed, the FROM clause will have two tables, but for now we just want to get the Location table working. By using the ‘SELECT *’ strategy, we remove any possible errors from line 1. From there, we can focus on the more complicated logic used for joining tables together. We can add tables one at a time until everything is working. This is the Organize phase. NOTE: SELECT * never results in an Error message stating “invalid column name”, however; a SELECT list with itemized field(s) can have this error. After our query is organized and working, we can go back and itemize the SELECT field list to display only the fields that are necessary. This is done during Phase II (Itemize). The steps for this system are broken down as follows: Since SELECT is always the first statement in a query, it’s natural to want to write the field names before writing the FROM clause. However; we can save time and trouble by using the ‘*’ until the entire query is working properly. When this is complete, it is very easy to itemize the field list, with the confidence of knowing it will not cause any problems. Exercise: Simple membership for a club: Table1 (id_Member,name_Member, email_member, title, age, company) Table2 (id_Club,club_name, club_Location, address) Table3 (id_club, id_member,membership_date) Q1: Show all member names, email, age, and company from Table1 Q2: Show all club name, location, and address data Q3: Show member name, club name, club location (hint: Use joins and all 3 tables) You can find all other classes related to this video here: http://www.joes2pros.com/joes2pros/Course/Introduction_To_Microsoft_SQL_Server Enroll Today & Get the First Month for only $1!

7. Compile-time warnings help avoid "WHEN OTHERS THEN NULL".
 
03:23
One of Tom Kyte's favorite pet peeves, the following exception sections "swallow up" errors. EXCEPTION WHEN OTHERS THEN NULL; EXCEPTION WHEN OTHERS THEN DBMS_OUTPUT.PUT_LINE (SQLERRM); In fact, any exception handler that does not re-raise the same exception or another, runs the risk of hiding errors from the calling subprogram, your users, and yourself as you debug your code. Generally, you should log the error, then re-raise it. There are certainly some cases in which this advice does not hold (for example: a function that fetches a single row for a primary key. If there is no row for the key, it's not an application error, so just return NULL). In those cases, include a comment so that the person maintaining your code in the distant future knows that you weren't simply ignoring the Wisdom of the Kyte. Example: EXCEPTION WHEN OTHERS THEN /* No company or this ID, let calling subprogram decide what to do */ RETURN NULL; One way to avoid this problem is to turn on compile-time warnings. Then when your program unit is compiled, you will be warned if the compiler has identified an exception handler that does not contain a RAISE statement or a call to RAISE_APPLICATION_ERROR.
