Useful Scripts for SQL Server 2000

/*
I work mostly on SQL Server 2000, and try to be as dynamic as possible. For this reason i created some SCRIPTS.
*/

/*
1. This SCRIPTS will return all the tables in a database.
It is useful if you want a select or delete query for every table.
*/

FETCH NEXT FROM ALLTABLES INTO @TABLENAME

WHILE @@FETCH_STATUS = 0
BEGIN
PRINT 'SELECT top 100 * FROM [' + @TABLENAME + ']'
--PRINT 'DELETE FROM [' + @TABLENAME + ']'
FETCH NEXT FROM ALLTABLES INTO @TABLENAME
END

CLOSE ALLTABLES
DEALLOCATE ALLTABLES

/*
3. Now to put the above knowledge into something important (atleast for me)
If you change the SELECT query to the one shown below, then it will only the first columns of each table, a good way to return the primary keys of tables, usually the first column of each table is the primary key. It will also be helpful if you want to make a fucntion, that return the next primary key value to help you inserts records.

SELECT SO.[NAME], SC.[NAME], SC.* FROM
SYSOBJECTS SO INNER JOIN SYSCOLUMNS SC ON SO.ID = SC.ID
WHERE SO.XTYPE='U' AND SYSSTAT <> 8275
AND SC.COLORDER = 1
ORDER BY SO.[NAME], SC.[NAME]

This script will return a script that will create a function, which takes as input a tablename and returns the next primary key value if the primary key is a numeric field.

How to execute this procedure
SELECT [dbo].[fnGetIDByName]('TABLENAME')

ANOTHER USE
INSERT INTO TABLENAME(PRIMARYKEY, ANYFIELD, ...)
VALUES ([dbo].[fnGetIDByName]('TABLENAME'), @ANYFIELD, ....)

There could be better use of this kind of scripts.
And there could be better ways of writing them as well. This is to my knowledge.

The important thing is the SYS.... tables in a SQL Server databases. They are tables that keep all the information about user tables, views, procedures etc. If you look closely in them, the primary key in them is the [id] field, make joins with it and you can get every bit of information about the database that you are working on.

Hijri Calendar


VS.NET is cool, and you can do cool things with it as well.
I had a problem of saving Hijri dates in an application. To solve it i made a DateTimePicker for Hijri calendar. But in hijri calendar the main problem is of not knowing the number of days in a month and also not knowing on which date, which day will fall. As hijri calendar is based on Moon. If you see the moon then the months starts, and so no one can predict the dates.

The other problem, is showing arabic dates in Arabic numerals or characters.

So in my calendar, i dont have options like Day names or the number of days in a month. It contantly shows 30 days.

had to work hard to make it, but after completeion it looks cool.

Here is some things that are needed to complete this task in Visual Basic.Net

Import these classes.

Imports System.Threading
Imports System.Globalization

Convert the current date to Hijri date.
Dim myCal As New HijriCalendar
Year = myCal.GetYear(Now)
Month = myCal.GetMonth(Now)
Day = myCal.GetDayOfMonth(Now)

But if you want to show Arabic numerals as well.

"٠١٢٣٤٥٦٧٨٩" Numerics
"محرم", "صفر", "ربيع الأول", "ربيع الثاني", "جمادىالأولى", "جمادىالأخرة", "رجـــب", "شعبان", "رمضان", "شوال", "زوالقعدة", "زوالحجة" Months

All you need now is some functions to return the arabic numerals for english and the month name for specific month.

In SQL Server.

you can easily convert a varchar date to hijri date through

select CONVERT(datetime, '16/04/1426 5:51:59:967PM', 130)
Return '2005-05-25 17:51:59.967'

select CONVERT(nvarchar, getdate(), 130)
Return '16 ربيع الثاني 1426 5:53:00:5'
select CONVERT(nvarchar, getdate(), 131)
Return '16/04/1426 5:53:00:500PM'

The values 130 and 131 are called the Quati Algorithm to convert dates


Rest is all logic that you use to make this happen.
