I have create procedure code, what is a delete procedure code.
Create procedure [dbo].[saveemp]
#Empname varchar(50),
#EmpAddress varchar(50),
#EmpDOB int,
#EmpGender varchar(50)
as
begin
insert employee(Empname, EmpAddress, EmpDOB, EmpGender)
values (#Empname, #EmpAddress, #EmpDOB, #EmpGender)
end
you are missing into in insert statement
insert into employee(Empname,EmpAddress,EmpDOB,EmpGender)
values
(#Empname,#EmpAddress,#EmpDOB,#EmpGender)
for deleting row using procedure
Create procedure [dbo].[deleteempname]
#Empname varchar(50)
as
BEGIN
DELETE FROM employee WHERE Empname= #Empname
END
Are you looking for "drop procedure"? http://technet.microsoft.com/en-us/library/ms174969.aspx
To delete the whole table, your query will be,
DELETE FROM employee
And to delete a single row (depending upon a parameter) it will be like,
DELETE FROM employee WHERE EmpName= #EmpName
It will be better if you delete a row depending upon the primary key (if you have any),
DELETE FROM employee WHERE EmpID = #EmpID

I have a table in my app
CREATE TABLE VisitDetails (VisitId INTEGER, UserId TEXT, VisitNumber
TEXT, JobId INTEGER, JobNumber TEXT, StatusId INTEGER, Status TEXT,
SignatureRequired BOOL, StatusDate TIMESTAMP DEFAULT CURRENT_TIMESTAMP
,StartDate TIMESTAMP DEFAULT CURRENT_TIMESTAMP, EndDate TIMESTAMP
DEFAULT CURRENT_TIMESTAMP, IsPPMJob BOOL)
and it was working fine but now I need to alter this table to make already existing column 'VisitId' to become the primary key. Can somebody help me please? It might work by adding Unique constraint to VisitId column of the table but I am trying to put some efficient solution !
You can't change SQLite tables field's primary key once the table is created,
Possible solution is,
Create new table with desired primary key
Copy all data
Drop old table
Here is the documentation link : https://www.sqlite.org/omitted.html

I have a database table with these columns:
Banner_Title varchar(500)
Existing_Banner_Image varchar(500)
Banner_URL varchar(500)
Banner_ALT varchar(500)
CheckBoxText varchar(500)
[for these 3 checkboxes have taken chkArticles,chkFittness,chkHealthArticle
but I want to check checkboxes also while insertion of data.For that I added one extra column in datatable named as sectionId for chkArticle checkbox I will assign 10 as a sectionId ,for chkFittness sectionId 11 and for chkHealthArticle as 12 so when I insert banner_title='article1', click chkArticle checkbox and fill other field data as mentioned in table format from then data should insert but next time when I try banner_title='article1' and click same checkbox then data not allowed to insert.but when I give banner_name='article1' and click another checkbox chkFittness it should allowed though the name of banner is same but maintained sectionid for checkboxes is different then what changes need to do stored procedure?? Basically I want to maintained unique banner_title for each checkbox click and to differentiate I maintained sectionid.plz help me
Create Unique constraint:
USE YourDatebase;
GO
ALTER TABLE YourTable
ADD CONSTRAINT YourConstraintName UNIQUE (Banner_Title);
GO
Check if banner title exists before insert attempt:
IF NOT EXISTS(SELECT Banner_Title FROM YourTable WHERE Banner_Title =
'TitleYourAreAttemptingToInsert')
BEGIN
INSERT .....
END

Create an index-by table and populate with rows from emp, then loop over and print them.
hi can anyone understand this question and give me the suggestions to solve this please..
A collection is an ordered group of elements having the same data type
which can be accessed though subscript/index. Oracle PL/SQL supports
three different types of collection
Index-by tables or Associative array
Nested table
Variable-size array or Varray
Below is an example of how you can define a Index-by table and populate it with rows from Emp table and print them accordingly.
DECLARE
CURSOR c_emp is
select name from emp;
TYPE c_list IS TABLE of emp.name%type INDEX BY binary_integer;
name_list c_list;
counter integer :=0;
BEGIN
FOR n IN c_emp LOOP
counter := counter +1;
name_list(counter) := n.name;
dbms_output.put_line('Employee('||counter|| '):'||name_list(counter));
END LOOP;
END;
/
See Oracle Documentation as well as PL/SQL - Collections for more information on the same.

Get the last record from a Microsoft SQL database table using ASP.net (VB) onto a web form.
I'm assuming he's trying to retrieve the last inserted record. As Ariel pointed out, the question is rather ambiguous.
SELECT TOP 1 * FROM Table ORDER BY ID DESC
If you have an identity column called ID, this is easiest. If you don't have an identity PK column for example a GUID you wont be able to do this.
Here is a basic solution:
var order = (from i in db.orders
where i.costumer_id.ToString() == Session["costumer_id"]
orderby i.order_id descending
select i).Take(1).SingleOrDefault();
You need to be more specific with actually putting it onto a web form, but the SQL to get the last record is:
SELECT *
FROM TABLE_NAME
WHERE ID = (SELECT MAX(ID) FROM TABLE_NAME)
Where ID is your ID and TABLE_NAME is your table name.
