Thanks in Advance

Hi ppl
Take a look a simple query.
String sql = (@"
SELECT Ins_ID, Ins_Nm
FROM Institution_Profile
WHERE Ins_ID = '{0}'
", combobox.Text);
If the query above works perfect without no erro then why the below query is not working.
String sql = (@"
SELECT Ins_ID, Ins_Nm
FROM '{0}'
WHERE Ins_ID = '{1}'
", tableName.text, Ins_ID.Text);
Anybody ans this pls
Thanks

It might be that you have made a typo.
Try changing tableName.text, Ins_ID.TexttableName.Text, Ins_ID.Text.
But on the other hand it could be anything. If you ask a question about an error, tell people what the error is and which part of the posted code gives the error, otherwise most members will ignore you.
Also please don't use text speak in your posts. We older folks don't understand it and once again you are cutting down the number of people willing to help you.

Remove the single quotes from the tablename: FROM '{0}' becomes FROM {0}.

This continues to be vulnerable to SQL Injection attacks.

To paraphrase dialog from the film 'Riddick': The CPer in me says that he has only just started learning SQL and nobody has given the little bit of help that he needs to continue with his project. However, the pedant in me says that I should tar and feather him for not following established best practice at all times; Ignorance of the Law is not a defence.

You should be using parameterised queries rather than injecting values into a SQL Statement. This is easy for data elements like the ID value, but slightly more difficult, yet doable, for the table name. As it stands your code is vulnerable to attack.

How to retrive attribute Name
<names>
<zipcode zc="*">
<rule rll="%LEIN">
Here the thing is in some Names tag the attribute of Rule is RL or RLL.
<rule rll="%LEIN">
<rule rl="LE%">
I am getting error at bold line below. Bcz, i mentioned direcly RLL. If RL exists as attirbute then getting error. how to get attribute name?
XmlNodeList NameList = doc.GetElementsByTagName("Names");
foreach (XmlNode node in NameList)
{
XmlElement nameElement = (XmlElement)node;
foreach (XmlNode xnode in nameElement)
{
XmlElement childElement = (XmlElement)xnode;
if (childElement.Name.ToLower() == "rule")
{
if (childElement.HasAttributes)
strrule = childElement.Attributes["RLL"].InnerText.ToLower();
}
}
}

Don't want to give stored proc to client? What are your options if there is one?
Thanks

Have you considerd encrypting it?

I didn't know you can encrypt them? (stored proc in db owned by client)

You can in SQLServer, don't know about the others, but why worry if its in their database? Have you hidden some sort of malicious timebomb code in the proc?

timebomb? no, just good code i plan to charge for money (as off-the-shelf-app)

Best option is to not give the password to the user. If the database is his/hers, then you should behave like a good guest within that database.
They're not going to put you out of business by copying your sprocs. People don't bother with that kind of thing, they just come here to ask for the code

haha that's so true though

In which case why not just put your business logic in the application - which generally they will be able to de-compile anyway
Its a constant battle to keep your code secure, but in my (25+ years) experience if you are selling to proper businesses they will respect your licence agreement.

becuase it's more optimized in stored proc

thanks anyway, just checking to see if I've missed anything

Add the stored proc in code on app start then drop it on app close. Of course if the app crashes, you're stuffed.
Out of interest, why wouldn't you want the client to have the proc?

no - thing is, because I want this to be highly optimized and best place to put the logic is actually in database. Dilemma is now i have to give away the source code.
Perhaps what I can do is to encapsulate only half in stored proc, the other half in obfuscated dll =)

you can use encryption. Eg.
create proc MyProc with Encryption
(
@parameters....
)
as
select query.....
BTW why dont you use .
google [^]
hope it helps...

AFAIK you could play around with the permissions, ie execute only to all but the developer. This will not secure your code but will reduce your exposure. The actual text of the code is stored in a sys table and is accessible to anyone with the right permissions (sa) and the knowledge to get at it.
I'd go with the license option - most clients are not SW people and only want to use the toll not reinvent it.
