Hi
What does the brackets around column names mean??
SELECT [Data] FROM Table
Please help
|
|
|
|
|
The brackets are used to escape any syntax that might otherwise be confused with a SQL keyword, or to allow spaces to appear in a column name.
In some contexts Data is a SQL keyword, but not actually in the column list of a SELECT statement. However, the brackets don't do any harm, so you can leave them in.
|
|
|
|
|
Signifies that the code elements between the square brackets can optionally appear in the SQL query, but are not required. Note that these brackets are not part of the code and must not appear in the SQL query.
|

Actually the brackets can appear in the SQL query. They just signify some text string that is its own entity, such as a table name composed of two words with a white space delimiter. You could also use it in a query like this:
SELECT columns FROM table WHERE column LIKE '%[%]%'
Which essentially escapes the middle percent sign, treating it like a percent sign instead of a wildcard character. I hope this helps.

What I am currently doing now is trying to have a backup on database and transaction log on databaseA. But when i tried to restore the transaction log of databaseA to databaseB. It occurred an error.
Msg 3154, Level 16, State 4, Line 1
The backup set holds a backup of a database other than the existing 'Test_Remote' database.
Msg 3013, Level 16, State 1, Line 1
RESTORE LOG is terminating abnormally.
How do i resolve this problem? Such that if i restore transaction log from one database to the other, it won't have an error?
Thanks

This cannot be done. Transaction logs are associated with a specific database and cannot be applied to a different database.

select *
from TABLE1 A
INNER JOIN TABLE2 B
ON A.STUDENT_ID = B.STUDENT_ID
INNER JOIN TABLE3 C
ON A.CLASS_ID = C.CLASS_ID
INNER JOIN TABLE4 E
ON A.FORM_ID = E.FORM_ID,
TABLE5 D
INNER JOIN E
On D.SCHOOL_ID = E.SCHOOL
I want to use TABLE1 A to inner join on TABLE2 B, TABLE3 C, TABLE4 E and the TALBE4 E inner join on TABLE5 D. But I get an error
"Invalid object name 'E'."
Thanks for helping

Oh. I get the answer la. It should be
select *
from TABLE1 A
INNER JOIN TABLE2 B
ON A.STUDENT_ID = B.STUDENT_ID
INNER JOIN TABLE3 C
ON A.CLASS_ID = C.CLASS_ID
INNER JOIN TABLE4 E
ON A.FORM_ID = E.FORM_ID
INNER JOIN TABLE5 D
On D.SCHOOL_ID = E.SCHOOL
Thanks

You are injecting values into the SQL String - This is a potential security flaw in your application and you should resolve it. See SQL Injection Attacks and Tips on How to Prevent Them[^]
The resoltion for the security flaw is also the resolution for your problem. You should use Parameterised queries to insert binary data.

Hello there
I need to find out the Columns that make up a key in an existing table...
Say I have a TABLE named USERS, I create a connection and I have a CADOREcordset to that table say we call it cUSERS... It has several keys, one of them is "USERID", I need to find a way (using ADO) to find out what columns make up that Key...
Looking for help, a function like CSTring CgetColumns("USERID"); will be just fantastic...
Cheers

I am trying to install SQL EXPRESS on my PC to run with VS 2005.
I had previously uninstalled it.
Now when I try (re)install it won't proceed thru the final steps, showing:
"Existing components have been found" - all options are greyed out & I cannot install.
Any ideas?
Any help is greatly appreciated.

First off, this is a rather complicated mixup I ended up in so I apologize if I'm not being clear enough. If you have any questions, don't hesitate to ask as I greatly appreciate any help you guys can give me on this....
I'm having trouble trying to read tables & stored procedures in Sql 2000's Enterprise Manager, that were originally written in Sql Server 2005. Is there any way I can view this 2005 data in Enterprise Manager?
I started working for a new company a few months ago and was told to develop my first project in the asp.net 2.0 framework & sql server 2005. So for 2 months, I've been developing this project only to discover they made a mistake & told me the wrong thing. All web applications need to use the 1.1 framework and sql server 2000 (They're console apps were the ones that were using 2.0 and sql 2005).
So I spent last week downgrading my application to 1.1 and today, I started downgrading my database stuff to sql 2000. I uninstalled Sql Server 2005 and installed Sql Server 2000. Now however, I'm unable to use Enterprise Manager to open any databases that were created in Sql 2005. I keep getting an error which says to open the tables in Sql 2005.
So my question is, even though I can't view this 2005 data in Enterprise manager, will the stored procedures I create in Sql 2000 still be able to reference any tables & views created in Sql 2005?
Thanks in advance.

As a general rule, you cant view or access data or procedures in databases created with a newer release of SQL server (SQL7 didn't like SQL2K either). You should, however, be able to use SQL2005 tools to script the database, then recreate the structures and procedures in an SQL2000 database (the scripts might need editing to account for SQL2K5 specific feature/syntax usage). Youl'll have to "downgrade" your databases as well...

Basically I want graphs. Like in Excel based on the data, readymade graphs can be made. Is this possible with SQL Server 2000???

SQL Server can certainly provide the data for the graphs, but it cannot draw them.

Hi,
I am using datasets to work with the data and populate text boxes appropriately. Something like:
textBox1.Text = dataset.table["tableName"].Row[0].column["LastName"]
In some books, they do databinding like:
textBox.DataBindings.Add("Text", _
table, table.Columns(I).ColumnName)
Which of these methods is better to get used to?
Are these two methods basically the same thing.
Thanks

Personally, I find data binding to be a real PITA! It always has some limitation which I need to get around, so invariably I just don't use it.

Yes and No
If you want to save the data back to the database and use update on the dataadapter, then databinding knows where to pick the values for fields from. If not, and you are doing it manually, there is not much difference.

Hey guys.
A little question on transaction best practices:
1. Where do you put your transaction control code? I mean: Do you put it in the code (try catch rollback()), or do you put it in the stored procedure?
2. Do you use transactions for simple insert, delete, update sentences?
Best Regards
Soeren

Stored Procedure usually, but sometimes I'll need to do several things in sequence so I'll managet the transaction in .NET
Bad Robot wrote: 2. Do you use transactions for simple insert, delete, update sentences?
If it is a simple oneliner then no because SQL Server, by default, will automatically put that in a transaction for me.
