Sorry....

But what does the right( do (i used select right(space(20) + 'TEST', 25)? i tested the also with select left(space(20) + 'TEST', 25)... i did not notice a difference.

What does the left or right do in this section?

select replicate('.', 9 - len(ltrim(rtrim(TestColumnValue)))) + ltrim(rtrim(TestColumnValue))
from YourTable

and this will left prefix with '.' character your field.

Try Convert.IsDBNull(dg.currentrow[5].cell.value).

Yes, I even try to figure out the reason, I'm puzzled still.

Why can't be -> sp.StateProvinceID = p.StateProvinceID, instead of p.StateProvinceID = p.StateProvinceID ?

It's a typo. It should be

sp.StateProvinceID = p.StateProvinceID

Hi,
Anyone knows how to use login control and how to connect it with the SQl server 2005 and connect to the table within my application database. So it can match the values from the table I have already created in my database.

SQL-Server assumed that you wanted an integer result because both of the operands were integers.

Try: select convert(float, 5) / 7

how to make many foreign key from one table [modified]

hi there,
i have 2 table, first have 2 columns(ID, Name) here ID is primary key
second have 9 columns (ID, 1, 2, 3, ... 8) here ID is primary key too

in second table column names from 1 to 8 have ID Numbers from Table First(which is primary)
and i want to make them foreign keys (from 1 to 8) so that if i delete ID from first table then the action that is set to "Set Null" will set that cell to null
for example
first table have data like this
[ID] [Name]
15 ABC
16 ERT
17 GHJ
18 LKI

in second table :
[ID]_[1]__[2]__[3]__[4]__[5]__[6]__[7]__[8]
14___16___18___17___15___17___17___15___15
15___18___18___17___16___18___18___17___15
16___15___18___16___15___17___17___16___15

now what i want, if i delete ID 16 from first table then the value 16 in table second shoul be set to "null" (from 1 to 8) so it will look like this:

[ID]_[1]__[2]__[3]__[4]__[5]__[6]__[7]__[8]
14________18___17___15___17___17___15___15
15___18___18___17________18___18___17___15
16___15___18________15___17___17________15

to do that i make 8 relationships, and set all actions as
update = cascade
delete = set null
but when i save it, it give error

'firsttable' table saved successfully
'secondtable' table
- Unable to create relationship 'FK_secondtable_II_firsttable'.
Introducing FOREIGN KEY constraint 'FK_secondtable_II_firsttable' on
table 'secondtable' may cause cycles or multiple cascade paths.
Specify ON DELETE NO ACTION or ON UPDATE NO ACTION,
or modify other FOREIGN KEY constraints.
Could not create constraint. See previous errors.

i want both actions, but sql is not allowing me to do that

it can be done by this, but i dont want to use this method

update secondtable set [1] = NULL where [1] = 
update secondtable set [2] = NULL where [2] = 
update secondtable set [3] = NULL where [3] = 
update secondtable set [4] = NULL where [4] = 
update secondtable set [5] = NULL where [5] = 
update secondtable set [6] = NULL where [6] = 
update secondtable set [7] = NULL where [7] = 
update secondtable set [8] = NULL where [8] =

some have any solution?
thanks

A few quick tips:
* Use parameters as much as possible.
* Validate EVERYTHING.
* If you are needing to dynamically set the name of tables or columns then have your SQL check the existance of the table first (A lookup on INFORMATION_SCHEMA.TABLES and INFORMATION_SCHEMA.COLUMNS will help here - remember to use parameters to pass the table name)
* Validate EVERYTHING.
* Run the code in the most restrictive account possible.
* Validate EVERYTHING.* Call stored procedures and have the SP validate the parameters and generate the dynamic SQL.
* Validate EVERYTHING.

recently i appeared for an exam... below question was asked:
You work as a database administrator.
You need to install a new SQL Server 2005 instance on a newly installed Windows
Server 20003 server named Server2. This new instance must have the same settings as the existing SQL Server 2005 instance on a server named Server1.
The only two services that need to be installed are the SQL Server service and the
SQL Server agent service.
The default installation folder should be used for the new SLQ Server instance on Server2. You will be able to refer to Server1 to view the settings to use.
You need to complete the installation wizard on Server2.

What operations do i need to perform....
(i dnt hv much experience on sql i am a beginner.)
