Oracle tutorial : sys_refcursor  in oracle pl sql (sys_refcursor)
 
09:53
Oracle tutorial : sys_refcursor in oracle pl sql oracle tutorial for beginners cursor in pl sql we can use sys_refcursor as OUT parameter. A cursor is a pointer to a result set for a query. By returning a sys_refcursor you allow the client to fetch many rows from the query as it requires. basically we use sys ref cursor to return set of rows to client. so client can use this result set. u can fetch multiple rows. lets see example.. CREATE OR REPLACE PROCEDURE get_my_list (list OUT SYS_REFCURSOR) AS BEGIN OPEN list FOR SELECT ALTID, FNAME, LNAME FROM EMPLOYEE; END get_my_list; / DECLARE l_cursor SYS_REFCURSOR; ID VARCHAR2(20); FNAME VARCHAR2(20); LNAME VARCHAR2(20); BEGIN get_my_list (list = l_cursor); LOOP FETCH l_cursor INTO ID, FNAME, LNAME; EXIT WHEN l_cursor%NOTFOUND; DBMS_OUTPUT.PUT_LINE(ID || ' | ' || FNAME || ' | ' || LNAME); END LOOP; CLOSE l_cursor; END; / Subscribe on youtube: https://www.youtube.com/channel/UCpiyAesWNYOXSz5GPq8lbkA For more tutorial please visit #techquerypond https://techquerypond.wordpress.com https://twitter.com/techquerypond database cursor example database cursor sql server cursor

Let us understand this with an example. SQL script to create Employees table Create table Employees ( ID int primary key identity, FirstName nvarchar(50), LastName nvarchar(50), Gender nvarchar(50), Salary int ) Go Insert into Employees values ('Mark', 'Hastings', 'Male', 60000) Insert into Employees values ('Steve', 'Pound', 'Male', 45000) Insert into Employees values ('Ben', 'Hoskins', 'Male', 70000) Insert into Employees values ('Philip', 'Hastings', 'Male', 45000) Insert into Employees values ('Mary', 'Lambeth', 'Female', 30000) Insert into Employees values ('Valarie', 'Vikings', 'Female', 35000) Insert into Employees values ('John', 'Stanmore', 'Male', 80000) Go We want to write a dynamic sql statement that returns total number of male of female employees. If the gender value is specified as "Male", then the query should return total male employees. Along the same lines, if the the value for gender is "Female", then we should get total number of female employees. The following dynamic sql, will give us what we want. In this case, the query returns total number of "Male" employees. If you want the total number of female employees, simply set @gender='Female'. Declare @sql nvarchar(max) Declare @gender nvarchar(10) Set @gender = 'Male' Set @sql = 'Select Count(*) from Employees where [email protected]' Execute sp_executesql @sql, N'@gender nvarchar(10)', @gender At the moment we are not using output parameters. If you want the count of employees to be returned using an OUTPUT parameter, then we have to do a slight modification to the query as shown below. The key here is to use the OUTPUT keyword in your dynamic sql. This is very similar to using OUTPUT parameters with a stored procedure. Declare @sql nvarchar(max) Declare @gender nvarchar(10) Declare @count int Set @gender = 'Male' Set @sql = 'Select @count = Count(*) from Employees where [email protected]' Execute sp_executesql @sql, N'@gender nvarchar(10), @count int OUTPUT', @gender, @count OUTPUT Select @count The OUTPUT parameter returns NULL, if you forget to use OUTPUT keyword.. The following query returns NULL, as we removed the OUTPUT keyword from @count parameter Declare @sql nvarchar(max) Declare @gender nvarchar(10) Declare @count int Set @gender = 'Male' Set @sql = 'Select @count = Count(*) from Employees where [email protected]' Execute sp_executesql @sql, N'@gender nvarchar(10), @count int OUTPUT', @gender, @count Select @count

Learn in depth about cursor in oracle database 11g, and why to use cursor.Writing Implicit cursor and explicit cursor following using 'for loop' inside cursor to fetch multiple records from oracle database. Cursor in Oracle Cursor in PL/SQL Oracle Cursor PL/SQL Cursor What is cursor in PL/SQL How to use cursor in PL/SQL Implicit cursor in PL/SQL Explicit cursor in PL/SQL A cursor is a pointer to this context area. PL/SQL controls the context area through a cursor. A cursor holds the rows (one or more) returned by a SQL statement. The set of rows the cursor holds is referred to as the active set. Implicit Cursors Implicit cursors are automatically created by Oracle whenever an SQL statement is executed, when there is no explicit cursor for the statement. Programmers cannot control the implicit cursors and the information in it. %FOUND Returns TRUE if an INSERT, UPDATE, or DELETE statement affected one or more rows or a SELECT INTO statement returned one or more rows. Otherwise, it returns FALSE. %NOTFOUND The logical opposite of %FOUND. It returns TRUE if an INSERT, UPDATE, or DELETE statement affected no rows, or a SELECT INTO statement returned no rows. Otherwise, it returns FALSE. %ISOPEN Always returns FALSE for implicit cursors, because Oracle closes the SQL cursor automatically after executing its associated SQL statement. %ROWCOUNT Returns the number of rows affected by an INSERT, UPDATE, or DELETE statement, or returned by a SELECT INTO statement. Explicit Cursors Explicit cursors are programmer-defined cursors for gaining more control over the context area. An explicit cursor should be defined in the declaration section of the PL/SQL Block. It is created on a SELECT Statement which returns more than one row Linkedin: https://www.linkedin.com/in/aditya-kumar-roy-b3673368/ Facebook: https://www.facebook.com/SpecializeAutomation/

Oracle DECODE Function
 
04:31
https://www.databasestar.com/oracle-decode-function/ The Oracle DECODE function lets you perform IF-THEN-ELSE functionality in your queries. It’s similar to a CASE statement. The syntax of the DECODE function is: DECODE ( expression, search, result [, search, result]... [,default] ) The parameters of the Oracle DECODE function are: - expression (mandatory): This is the value to compare. - search (mandatory): This is the value to compare against the expression. - result (mandatory): This is the return value if the search value matches the expression value. There can be multiple combinations of search and result values, and the result value is attached to the previous search value. - default (optional): If none of the search values match, then this value is returned. If this is not provided, the DECODE function will return NULL if no matches are found. If you compare this to an IF-THEN-ELSE statement, it would look like this: IF (expression = search) THEN result [ELSE IF (expression = search) THEN result] ELSE default END IF The parameters can be one of many different data types, and the return type is calculated from them. Earlier I mentioned it’s similar to CASE. So why would you use one and not the other? - DECODE is an older function, and CASE was introduced as a replacement for DECODE. - CASE offers more flexibility then DECODE - CASE is also easier to read and debug (in my opinion) The performance of these functions is the same, so if you’re considering using DECODE, I would suggest using CASE instead. For more information about the Oracle DECODE function, including all of the SQL shown in this video and the examples, read the related article here: https://www.databasestar.com/oracle-decode-function/

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.

Oracle Database11g tutorials 13 || SQL substr function / SQL substring function
 
06:34
link of SQL substr blog : http://www.rebellionrider.com/SQL-substr-function.htm SQL substr function SQL Substr function will return a sub string of a specified length from the source string beginning at a given position. Tool used in this tutorial is command prompt. This tutorial series is part of SQL expert exam certification training. if you are preparing for SQL certification you can use my tutorials. This SQL Tutorial is a part of free training.

Let's see the Syntax Substr (source_string, start_pos, Substr_length) As we can see SQL substr function takes 3 parameters. First one is Source string from which you want to extract the segment. Second parameter is Starting position for sub string from the Source string. And the third parameter is Substr_length which is the length for the substring. First two parameters are mandatory to specify while third one is optional. So we can say. SQL Substr function will return a sub string of a specified length from the source string beginning at a given position. First parameter source string can be of any data type CHAR, VARCHAR2, NCHAR, NVARCHAR2, CLOB, or NCLOB whereas both start_pos, Substr_length parameters must be number data type. The returning result of SQL Substr function is of same data type of source string. Let's see an example of SQL Substr function. SELECT substr('www.RebellionRider.com',5,14) FROM dual; Here in this query url of my website www.RebellionRider.com is our source string with the total length of 22 characters, Now, I want to extract the name of my website that is, RebellionRider. So if you count the total length of the name of the website, it is 14. That's why I have specified 14 as my third parameter of SQL Substr function which is substr_length. Also the name of the website RebellionRider is starting from 5th position therefore I have specified 5 at second parameter of SQL substr function which is strt_pos or starting position. Execute it. Here is our result RebellionRider When starting position is larger than the length of source string. In this case SQL Substr function will return NULL as a result. Let's do an example. SELECT substr('www.RebellionRider.com',23,14) FROM dual; As you can see here I have specified 23 at starting position and the total length of our source string is 22 characters Let's execute And the result is Null. Second scenario When the Substr_length is greater than source string In this case the segment return is the substring from starting position to the end of the string. For example SELECT substr('www.RebellionRider.com',5,23) FROM dual; Our starting position is at 5 means at the first R of RebellionRider and length of substring is set to 23 which is greater than the length of source string that is 22. Execute. As you can see we get a substring from first R of RebellionRider till the end of the source String. Third scenario When you supply numeric or arithmetic expression or a DATE instead of character as Source string to SQL Substr function In this scenario If you have supplied a numeric string instead of character as source string, the oracle engine casts them as a character when they occur as parameter to SQL Substr function. And if you have supplied Arithmetic expression or a DATE then The Oracle engine first solves or evaluates the Arithmetic expression or the DATE Then casts them as a character. Means if you have arithmetic expression in your source string then oracle will first solve it and then change or say cast the value of its result into character. Let's see some example. SELECT substr(50000-7,2,4) FROM dual; Oracle first evaluates the arithmetic expression that is 50000-7 equals to 49993. And then oracle engine casts this result 49993 into a character string. Means 49993 will be a 5 characters string. Starting position of substring is 2, that means from the first 9 of 49993 We specified the length of substring is 4 so we must get 9993 as our result. Let's check execute

Send datatable as parameter to stored procedure
 
09:27
how to pass datatable to stored procedure in c#.net pass datatable to stored procedure in sql server 2008 In this video we will discuss how to send datatable as parameter to stored procedure. This is continuation to Part 99. Please watch Part 99 from SQL Server tutorial before proceeding. In Part 99, we discussed creating a stored procedure that accepts a table as a parameter. In this video we will discuss how to pass a datatable from a web application to the SQL Server stored procedure. Here is what we want to do. 1. Design a webform to insert 5 employees at a time into the database table. 2. When "Insert Employees" button is clicked, retrieve the from data into a datatabe and then pass the datatable as a parameter to the stored procedure. 3. The stored procedure will then insert all the rows into the Employees table in the database. WebForm1.aspx.cs code using System; using System.Configuration; using System.Data; using System.Data.SqlClient; namespace Demo { public partial class WebForm1 : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) {} private DataTable GetEmployeeData() { DataTable dt = new DataTable(); dt.Columns.Add("Id"); dt.Columns.Add("Name"); dt.Columns.Add("Gender"); dt.Rows.Add(txtId1.Text, txtName1.Text, txtGender1.Text); dt.Rows.Add(txtId2.Text, txtName2.Text, txtGender2.Text); dt.Rows.Add(txtId3.Text, txtName3.Text, txtGender3.Text); dt.Rows.Add(txtId4.Text, txtName4.Text, txtGender4.Text); dt.Rows.Add(txtId5.Text, txtName5.Text, txtGender5.Text); return dt; } protected void btnInsert_Click(object sender, EventArgs e) { string cs = ConfigurationManager.ConnectionStrings["DBCS"].ConnectionString; using (SqlConnection con = new SqlConnection(cs)) { SqlCommand cmd = new SqlCommand("spInsertEmployees", con); cmd.CommandType = CommandType.StoredProcedure; SqlParameter paramTVP = new SqlParameter() { ParameterName = "@EmpTableType", Value = GetEmployeeData() }; cmd.Parameters.Add(paramTVP); con.Open(); cmd.ExecuteNonQuery(); con.Close(); } } protected void btnFillDummyData_Click(object sender, EventArgs e) { txtId1.Text = "1"; txtId2.Text = "2"; txtId3.Text = "3"; txtId4.Text = "4"; txtId5.Text = "5"; txtName1.Text = "John"; txtName2.Text = "Mike"; txtName3.Text = "Sara"; txtName4.Text = "Pam"; txtName5.Text = "Todd"; txtGender1.Text = "Male"; txtGender2.Text = "Male"; txtGender3.Text = "Female"; txtGender4.Text = "Female"; txtGender5.Text = "Male"; } } Text version of the video http://csharp-video-tutorials.blogspot.com/2015/09/send-datatable-as-parameter-to-stored.html Slides http://csharp-video-tutorials.blogspot.com/2015/09/send-datatable-as-parameter-to-stored_18.html All SQL Server Text Articles http://csharp-video-tutorials.blogspot.com/p/free-sql-server-video-tutorials-for.html All SQL Server Slides http://csharp-video-tutorials.blogspot.com/p/sql-server.html All Dot Net and SQL Server Tutorials in English https://www.youtube.com/user/kudvenkat/playlists?view=1&sort=dd All Dot Net and SQL Server Tutorials in Arabic https://www.youtube.com/c/KudvenkatArabic/playlists

Lead and Lag functions in SQL Server 2012
 
07:27
In this video we will discuss about Lead and Lag functions. Lead and Lag functions Introduced in SQL Server 2012 Lead function is used to access subsequent row data along with current row data Lag function is used to access previous row data along with current row data ORDER BY clause is required PARTITION BY clause is optional Syntax LEAD(Column_Name, Offset, Default_Value) OVER (ORDER BY Col1, Col2, ...) LAG(Column_Name, Offset, Default_Value) OVER (ORDER BY Col1, Col2, ...) Offset - Number of rows to lead or lag. Default_Value - The default value to return if the number of rows to lead or lag goes beyond first row or last row in a table or partition. If default value is not specified NULL is returned. We will use the following Employees table for the examples in this video SQL Script to create the Employees table Create Table Employees ( Id int primary key, Name nvarchar(50), Gender nvarchar(10), Salary int ) Go Insert Into Employees Values (1, 'Mark', 'Male', 1000) Insert Into Employees Values (2, 'John', 'Male', 2000) Insert Into Employees Values (3, 'Pam', 'Female', 3000) Insert Into Employees Values (4, 'Sara', 'Female', 4000) Insert Into Employees Values (5, 'Todd', 'Male', 5000) Insert Into Employees Values (6, 'Mary', 'Female', 6000) Insert Into Employees Values (7, 'Ben', 'Male', 7000) Insert Into Employees Values (8, 'Jodi', 'Female', 8000) Insert Into Employees Values (9, 'Tom', 'Male', 9000) Insert Into Employees Values (10, 'Ron', 'Male', 9500) Go Lead and Lag functions example WITHOUT partitions : This example Leads 2 rows and Lags 1 row from the current row. When you are on the first row, LEAD(Salary, 2, -1) allows you to move forward 2 rows and retrieve the salary from the 3rd row. When you are on the first row, LAG(Salary, 1, -1) allows us to move backward 1 row. Since there no rows beyond row 1, Lag function in this case returns the default value -1. When you are on the last row, LEAD(Salary, 2, -1) allows you to move forward 2 rows. Since there no rows beyond the last row 1, Lead function in this case returns the default value -1. When you are on the last row, LAG(Salary, 1, -1) allows us to move backward 1 row and retrieve the salary from the previous row. SELECT Name, Gender, Salary, LEAD(Salary, 2, -1) OVER (ORDER BY Salary) AS Lead_2, LAG(Salary, 1, -1) OVER (ORDER BY Salary) AS Lag_1 FROM Employees Lead and Lag functions example WITH partitions : Notice that in this example, Lead and Lag functions return default value if the number of rows to lead or lag goes beyond first row or last row in the partition. SELECT Name, Gender, Salary, LEAD(Salary, 2, -1) OVER (PARTITION By Gender ORDER BY Salary) AS Lead_2, LAG(Salary, 1, -1) OVER (PARTITION By Gender ORDER BY Salary) AS Lag_1 FROM Employees Text version of the video http://csharp-video-tutorials.blogspot.com/2015/10/lead-and-lag-functions-in-sql-server.html Slides http://csharp-video-tutorials.blogspot.com/2015/10/lead-and-lag-functions-in-sql-server_5.html All SQL Server Text Articles http://csharp-video-tutorials.blogspot.com/p/free-sql-server-video-tutorials-for.html All SQL Server Slides http://csharp-video-tutorials.blogspot.com/p/sql-server.html All Dot Net and SQL Server Tutorials in English https://www.youtube.com/user/kudvenkat/playlists?view=1&sort=dd All Dot Net and SQL Server Tutorials in Arabic https://www.youtube.com/c/KudvenkatArabic/playlists
