Hello Everybody!
I have a POLINE table on a SQL Server 2000 DB. Before I update the
record I need to check that either field, STORELOC or WONUM has data
on it. If both fields are NULL I would like to send a message letting
the user know that either fields needs data before they can save the
record. If any of the fields have data then, it is OK to save the
record.
Could you please let me know how to accomplish this? An example will

Hi all
In my functions I'm using a double-check all the time to trap if a value has
nothing in it and my question is do I need this double-check.
My check line is:
IF IsNull(xxx) OR LEN(xxx) = 0 THEN
blah blah

Hi,
I have following value which I need to check wether it's null or not. Issue is that StartPrice itself can be a null and checking (myItem.StartPrice.Value == null) do not produce true.
How do I check for null in this kind of case. I don't want to check StartPrice for null and then Value for null again as one option. I just want to check Value for null.
Thanks,
Greg

I have a Customer table. The table has two different CHECK constraints.
Then there is the Customer details dialog, which provides the user with
an UI for changing users. I have some UPDATE sql, which is called once
the user clicks the OK button on this dialog.
try
{
int rows = cmd.ExecuteNonQuery();
}
catch(SqlException se)

With the development of smart home technology, a variety of wireless communication protocols have appeared on the market, such as Zigbee, Z-Wave, Wi-Fi, Bluetooth, etc. Each protocol has its own unique characteristics and advantages, but as a user who is planning to build a smart home system, I am a bit confused by the choice of these technologies.

Let's talk about the concept of autonomous AI software engineers and no-code agents. These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention.
