SQL Null or Empty   How to Check for Null or Empty Column in SQL Server   SQL Training Online

http://www.sqltrainingonline.com SQL Null or Empty - How to Check for Null or Empty Column in SQL Server - SQL Training Online You can download the sample table script at http://www.sqltrainingonline.com/how-to-filter-for-sql-null-or-empty-string/. In this video, I show you how to filter for a SQL null or empty string. It can be difficult to filter a null because you can't simply compare with an equal sign. You have to use a special IS NULL clause to make the filter work. I also show you how to combine both the SQL Null and Empty String together in a special trick with the isnull SQL Server function. I use SQL Server 2012 to demonstrate the technique. Let me know what you think by commenting or sharing on twitter, facebook, google+, etc. If you enjoy the video, please give it a like, comment, or subscribe to my channel.

Oracle SQL Tutorial 13 - How to Add Column Constraints (Attributes)
 
05:55
So far, we have this table declaration: CREATE TABLE users( user_id NUMBER, username VARCHAR(50 CHAR) first_name VARCHAR2(50 CHAR), last_name VARCHAR2(50 CHAR) ) We can run this command see that it works. As we are learning though, we are going to want to be able to recreate our table with different settings and such, but if you try to run this command, it will complain that the table already exists. So we first need to delete this table before we start editing settings. When we get more experienced, we will learn about ways to edit the structure of a table that already exists. To fix this, we can get rid of the table using the DROP TABLE command: DROP TABLE users You can run this every time if you need to practice by adding a semicolon after it. This is how you can tell Oracle that you are putting in another command after it. This is known as a delimiter. When you run the script, it is going to run both commands. Now we can go through and reconsider our table structure. This is fine for starting out because we don't have any important data in our database, but once your database is in production you are not going to want to just drop tables. In the last video we discussed different constraints that you can apply to columns in a database table, but how do you actually apply these when you are creating a table? The first way you define constraints is to put them right after the column in your CREATE TABLE statement. CREATE TABLE users( username VARCHAR2(50 CHAR) NOT NULL ) When we define constraints this way, we usually say we are adding column attributes. If you have two constraints you want to add, you just put one after the other with spaces in between. There is no particular order that is required. CREATE TABLE users( username VARCHAR2(50 CHAR) NOT NULL UNIQUE ) In this situation we have already given the column the NOT NULL and UNIQUE attributes, so we should consider making this a primary key: CREATE TABLE users( username VARCHAR2(50 CHAR) PRIMARY KEY ) As you can see, adding column attributes is super easy. We can add a default like this: CREATE TABLE users( username VARCHAR2(50 CHAR) PRIMARY KEY, account_balance NUMBER DEFAULT 0 ) Note that now we need the comma after the first row. There are a few constraints we did not talk go through an example, specifically foreign keys and check constraints. We will be adding these constraints to our database in future videos. In the mean time, I have a thought for you… Many people prefer to name their column constraints. That way, we can refer to certain constraints by name. For example, we might have a primary key constraint that could be named users_pk. The way we are creating these constraints does not allow for this feature, so in the next video we are going to be discussing different ways to create constraints. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 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!)

MySQL 33 - Datetime, Date, Time Data Types
 
06:40
Next up on our MySQL to-do list is to learn about storing dates and times. There are various data types in MySQL for storing dates and times. It seems MySQL and databases likes to break everything up into multiple data types to make things more organized at the consequence of being confusing and annoying. This video is going to be talking about the DATETIME, DATE, and TIME data types. These are all used to store, you guessed it, dates and times. The one you choose depends on your needs. If you just need dates, choose DATE. If you just need times, choose TIME, if you need both stored together, choose DATETIME. Now you set a column one of these data types whenever you want every row for this field to have some sort of date, time or both…but how exactly is the data formatted? This requires us to understand some convention. For example, in the USA at least, if you have something like 4:30AM, by convention you know the hour is 4 and the minutes are 30. But this is just an agreed upon convention. MySQL has its own convention…For example 2017-02-02. The first thing is the year, the second is the month, and the third is the day. That is for the DATE. The convention for time is 22:54:30. The first is the hour (military time), the second is the minute, and the third is the seconds. Lastly, there can actually be fractions of seconds…up to microseconds! .123456. To use fractional seconds though you must specify to MySQL the precision of the TIME or DATETIME when you create it, for example DATETIME(6) would allow microsecond precision. How do you actually give a date to MySQL? By that I mean let's say you have a table with a column of DATETIME(6), and you want to give a value for that column, how do you format it? It's quoted. For example: '2017-02-02 22:54:30.333333' MySQL interprets this as a DATETIME. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Support me! 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!)

COALESCE Function in SQL ORACLE Query With Example
 
03:53
ORACLE/PLSQL: COALESCE FUNCTION The Oracle/PLSQL COALESCE function returns the first non-null expression in the list. If all expressions evaluate to null, then the COALESCE function will return null. The syntax for the Oracle/PLSQL COALESCE function is: coalesce( expr1, expr2, ... expr_n ) PARAMETERS: expr1 to expr_n are the expressions to test for non-null values. EXAMPLE: The COALESCE function can be used in Oracle/PLSQL. You could use the coalesce function in a SQL statement as follows: SELECT COALESCE( address1, address2, address3 ) result FROM suppliers; The above COALESCE function is equivalent to the following IF-THEN-ELSE statement: IF address1 is not null THEN result := address1; ELSIF address2 is not null THEN result := address2; ELSIF address3 is not null THEN result := address3; ELSE result := null; END IF; The COALESCE function will compare each value, one by one. Lets apply the same to emp table. We have some NULL values in comm and mgr columns. but not in any other columns. So lets take a example for this 2 columns. COALESCE(comm,mgr,sal) Here if comm is null, function returns mgr value. If mgr is null it returns sal value! Query used in video: SELECT ename,comm,mgr,sal,COALESCE(comm,mgr,sal) result FROM emp;

SQL: Check Constraint
 
05:11
In this tutorial, you'll learn how to make use of check constraint. PL/SQL (Procedural Language/Structured Query Language) is Oracle Corporation's procedural extension for SQL and the Oracle relational database. PL/SQL is available in Oracle Database (since version 7), TimesTen in-memory database (since version 11.2.1), and IBM DB2 (since version 9.7).[1] Oracle Corporation usually extends PL/SQL functionality with each successive release of the Oracle Database. PL/SQL includes procedural language elements such as conditions and loops. It allows declaration of constants and variables, procedures and functions, types and variables of those types, and triggers. It can handle exceptions (runtime errors). Arrays are supported involving the use of PL/SQL collections. Implementations from version 8 of Oracle Database onwards have included features associated with object-orientation. One can create PL/SQL units such as procedures, functions, packages, types, and triggers, which are stored in the database for reuse by applications that use any of the Oracle Database programmatic interfaces. PL/SQL works analogously to the embedded procedural languages associated with other relational databases. For example, Sybase ASE and Microsoft SQL Server have Transact-SQL, PostgreSQL has PL/pgSQL (which emulates PL/SQL to an extent), and IBM DB2 includes SQL Procedural Language,[2] which conforms to the ISO SQL’s SQL/PSM standard. The designers of PL/SQL modeled its syntax on that of Ada. Both Ada and PL/SQL have Pascal as a common ancestor, and so PL/SQL also resembles Pascal in several aspects. However, the structure of a PL/SQL package does not resemble the basic Object Pascal program structure as implemented by a Borland Delphi or Free Pascal unit. Programmers can define public and private global data-types, constants and static variables in a PL/SQL package.[3] PL/SQL also allows for the definition of classes and instantiating these as objects in PL/SQL code. This resembles usage in object-oriented programming languages like Object Pascal, C++ and Java. PL/SQL refers to a class as an "Abstract Data Type" (ADT) or "User Defined Type" (UDT), and defines it as an Oracle SQL data-type as opposed to a PL/SQL user-defined type, allowing its use in both the Oracle SQL Engine and the Oracle PL/SQL engine. The constructor and methods of an Abstract Data Type are written in PL/SQL. The resulting Abstract Data Type can operate as an object class in PL/SQL. Such objects can also persist as column values in Oracle database tables. PL/SQL is fundamentally distinct from Transact-SQL, despite superficial similarities. Porting code from one to the other usually involves non-trivial work, not only due to the differences in the feature sets of the two languages,[4] but also due to the very significant differences in the way Oracle and SQL Server deal with concurrency and locking. There are software tools available that claim to facilitate porting including Oracle Translation Scratch Editor,[5] CEITON MSSQL/Oracle Compiler [6] and SwisSQL.[7] The StepSqlite product is a PL/SQL compiler for the popular small database SQLite. PL/SQL Program Unit A PL/SQL program unit is one of the following: PL/SQL anonymous block, procedure, function, package specification, package body, trigger, type specification, type body, library. Program units are the PL/SQL source code that is compiled, developed and ultimately executed on the database. The basic unit of a PL/SQL source program is the block, which groups together related declarations and statements. A PL/SQL block is defined by the keywords DECLARE, BEGIN, EXCEPTION, and END. These keywords divide the block into a declarative part, an executable part, and an exception-handling part. The declaration section is optional and may be used to define and initialize constants and variables. If a variable is not initialized then it defaults to NULL value. The optional exception-handling part is used to handle run time errors. Only the executable part is required. A block can have a label. Package Packages are groups of conceptually linked functions, procedures, variables, PL/SQL table and record TYPE statements, constants, cursors etc. The use of packages promotes re-use of code. Packages are composed of the package specification and an optional package body. The specification is the interface to the application; it declares the types, variables, constants, exceptions, cursors, and subprograms available. The body fully defines cursors and subprograms, and so implements the specification. Two advantages of packages are: Modular approach, encapsulation/hiding of business logic, security, performance improvement, re-usability. They support object-oriented programming features like function overloading and encapsulation. Using package variables one can declare session level (scoped) variables, since variables declared in the package specification have a session scope.

Roman Asks A Psychic If He'll Ever Date Rita Ora
 
04:23
Her name is DEFINITELY short for Rita Oracle, right? RIGHT?! We may have made a huge, expensive mistake. We thought Rita's full name was Rita Oracle. So we spent all of this month's budget on tarot cards, ancient relics, smoke machines and a psychic. It turns out that that's not Rita's actual name. This. Is. Awkward. Still, when in Rome... The 'Your Song' singer popped by #CapitalBreakfastWithRomanKemp, and they pair of them got their futures read by a fully-fledged psychic, and it started off pretty well. According to Carrie, our fortune teller (http://www.carriekirkpatrick.com), One Direction ARE going to be making a comeback, so all is good. And - luckily for us - Roman Kemp and Vick Hope won't be getting fired anytime soon. Now, this is where it gets awkward... Roman asked/shouted at Carrie to see whether or not he and Rita will ever spark a romantic bond in the near-future. He would have known the answer too, if he didn't blank out as soon as Carrie said the word "sexual". All he heard was white noise from there. Having been told that Rita is an oracle when she sings, her, Roman and Carrie all joined hands and... Sang 'I Do Like To Be Beside the Seaside'. Obviously. Single-handedly, this is the most surreal moment of our lives. Subscribe: http://bit.ly/SubscribeToCapitalFM Get involved with the UK's No. 1 Hit Music Station!

CREATE TABLE tblEmployee ( Id int IDENTITY PRIMARY KEY, Name nvarchar(50), Email nvarchar(50), Age int, Gender nvarchar(50), HireDate date, ) Insert into tblEmployee values ('Sara Nan','[email protected]',35,'Female','1999-04-04') Insert into tblEmployee values ('James Histo','[email protected]',33,'Male','2008-07-13') Insert into tblEmployee values ('Mary Jane','[email protected]',28,'Female','2005-11-11') Insert into tblEmployee values ('Paul Sensit','[email protected]',29,'Male','2007-10-23') Name, Email, Age and Gender parameters of spSearchEmployees stored procedure are optional. Notice that, we have set defaults for all the parameters, and in the "WHERE" clause we are checking if the respective parameter IS NULL. Create Proc spSearchEmployees @Name nvarchar(50) = NULL, @Email nvarchar(50) = NULL, @Age int = NULL, @Gender nvarchar(50) = NULL as Begin Select * from tblEmployee where (Name = @Name OR @Name IS NULL) AND (Email = @Email OR @Email IS NULL) AND (Age = @Age OR @Age IS NULL) AND (Gender = @Gender OR @Gender IS NULL) End Testing the stored procedure 1. Execute spSearchEmployees - This command will return all the rows 2. Execute spSearchEmployees @Gender = 'Male' - Retruns only Male employees 3. Execute spSearchEmployees @Gender = 'Male', @Age = 29 - Retruns Male employees whose age is 29

SQL Tutorial - Create Table with Constraints
 
20:35
This video tutorial will show you how to create a table with constraints in Microsoft SQL Server. The video covers, data types of columns, NOT NULL constraints, PRIMARY KEY constraints, FOREIGN KEY constraints, CHECK constraints and DEFAULT constraints. Data types enforce limits to the what can inserted in to tables and constraints further build on this, for example if you wanted to add a column called age, the values will usually range from 0 - 100 so we could choose a data type of TINYINT which allows values of up to 255 but this means if you enter 255 this is still a valid age. We want to control this even further so we can add a CHECK constraint that will only allow values from 0 - 100. Check out the video for how to add this constraint. CREATE TABLE dbo.[Login] ( Username VARCHAR(30) NOT NULL CONSTRAINT PK_Login_Username PRIMARY KEY (Username) , [Password] VARCHAR(30) NOT NULL , LastUpdate DATETIME2 NOT NULL CONSTRAINT DF_Login_LastUpdate DEFAULT (CURRENT_TIMESTAMP) , [Status] CHAR(10) NOT NULL CONSTRAINT CK_Login_Status CHECK ([Status] IN ('Active', 'Inactive')) , CustomerID INT CONSTRAINT FK_Login_CustomerId FOREIGN KEY (CustomerId) REFERENCES Customers (CustomerId) )

Search Value In All Tables
 
04:25
This cursor is used for to search specific value or string value in all columns in all tables under SQL Server database. In this cursor you are specifying data type as varchar means this cursor will search specific value in only in varchar datatype, you can also change data type from varchar to any other data type like uniqueidentifier, datetime etc..

Foreign Key in Oracle oracle foreign key WHAT IS A FOREIGN KEY IN ORACLE? 1)A foreign key is a use to make referential integrity in database. 2)Foreign key values in one table must also appear in another table also. 3)The referenced table is called the parent table. 4)Table with the foreign key is called the child table. 5)The foreign key generally reference a primary key in the parent table. CREATE TABLE DEPT --- parent table ( DEPT_ID NUMERIC(10) NOT NULL, EMP_ID NUMERIC(10) NOT NULL, CONSTRAINT DEP_PK PRIMARY KEY (DEPT_ID) ); CREATE TABLE EMPLOYEE -- child table ( EMP_ID NUMERIC(10) NOT NULL, NAME VARCHAR2(50) NOT NULL, CITY VARCHAR2(50), DEPT_NO NUMERIC(10), CONSTRAINT ID_PK PRIMARY KEY (EMP_ID), CONSTRAINT FK_DEP FOREIGN KEY (DEPT_NO) REFERENCES DEPT(DEPT_ID) ); #techquerypond https://techquerypond.wordpress.com https://twitter.com/techquerypond
