How to handle NULL parameters,EMPT Y parameters and ERROR HANDLING in stored procedure

Soniad

Hello,

I have stored procedure in which i am passing parameters (varchar(8000)) ,
these parameters can have values or can be empty (''), i have written blocks of codes for each parameter , which executes only if parameter has values, it should not enter the block if parameter is empty,
how to detect whether the parameter is empty or not.

and also i am having output parameter (varchar(1)) that is returned by stored procedure, if all of the parameters has values then output parameter returns some value, if any of the parameters is empty, then it doesn't go till the line where OUPUT parameter is set to some value, thats y no value is returned.
can anyone help me to sort out this problem.

Regards,

"D"

You can actually give default values to those parameters during creation/definition.

Hi, I've been working through a number of turorials to try to learn more about retrieving data from a SQL database. I think i've mastered techniques where i create a sql string in the page and pass it to the Db and retrieveing data from a stored procedure, but I can't get the hang of parameters. I have a method where I can get the parameters passed to the sp but it doesn't want to return any results. Here's a copy of my code:

Is it possible to pass a null value to a stored procedure in .net? I have a search Sproc that can take one of two numbers to search on, but not both. I use the code below to pass a null value to the sproc if a TextBox is empty. SqlCommand getLesNumbers = new SqlCommand(); getLesNumbers.CommandText="usp_getLesNumbers"; getLesNumbers.CommandType = CommandType.StoredProcedure; getLesNumbers.Connection = msoConn;

I think I have discovered a bug in the handling of null values (vs NULL values) passed as parameters to a stored proc. I have always believed that the database handled NULL and null the same. The following statement returns the expected results: select case when NULL is null then 'SAME' else 'DIFFERENT' end from sysibm.sysdummy1; returns SAME.

I am using vb.net 2005 and SQL server 2000. In my table I have a date field of type "smalldatetime". In my vb application, the user may or may not enter a date value into the appropriate text box.

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
