SQL Insert - How To Combine More Than One Field Value To A Single Column Insert
Jan 18, 2010I have a form with many form fields and controls, with some offering an "other" if a value does not meet the needs for the user. How can I bind the sql insert so that it will take the ddl selection along with the txt field selection for the "other" value? Even if the txt field is empty it should not be a big deal since the ddl would provide something other than null. Since the column in the db does not allow nulls. I'm using asp.net (vb) 3.5 sp1

ADO.NET :: Insert A Null String Value Into An SQL Database?
Dec 22, 2010I'm having some problems with the interface I've created. After some searching, I've discovered that it is inserting an empty string into my database fields as opposed to an null value. I need my application to insert null values, not emptry strings. Can someone provide an example of how this is done?
View 2 RepliesSQL Server :: Insert Null Datetime Into DB?
Nov 4, 2010I have 2 textboxes for BEGINNING DATE and END DATE. First I compare the dates so that the END DATE is bigger than the BEGINNING DATE. This is OK with the validators.
MY PROBLEM IS: If the END DATE´S TEXTBOX is empty, then it should insert into the SQL DB, a null value. The field has a DATETIME type.
Since my INSERT Query requires a parameter when i call the ADD METHOD, it returns that the END DATE parameter is required.
Fluent NHibernate Cascade - Trying To Insert NULL ID?
Mar 8, 2011I have the following models & mappings (code snippets further below).
One Competition has to have multiple CompetitionAnswers associated with it (multiple choice) from the outset.
At present, using the Fluent NHibernate mappings shown below, when I create a brand new Competition object, populate the properties, then create 3 brand new CompetitionAnswer objects and add them to the CompetitionAnswers property (property on Competition), I would expect to call Save on the session which would INSERT the 1 Competition row and 3 CompetitionAnswer rows to the DB.
However, as soon as I try to call Save on the session, it complains that CompetitionId is null and it can't insert a null into the CompetitionAnswers table for that field - which is right, it shouldn't, however, I assumed that the NHibernate would first create the Competition, then use the newly generated IDENTITY value (CompetitionId) in the CompetitionAnswers table?

SQL Server :: Insert NULL Int Into Stored Procedure?
Jan 17, 2011I'm strugling with this problem for quite some time and I've tried many different solution but nothing works. In my application there are 3 textboxes. First is mandatory but user can leave second and third empty. I that case I want that application insert NULL.
Here is .aspx code:
[Code]....
c# code:
[Code]....
Stored procedure:
[Code]....
I've tested code when user fills all 3 textboxes and it's working fine. If one second or third (or both) textbox(es) is(are) empty I wish to insert NULL into table. I've tried with DbNull.Value, null, 0, "3232131" and nothing works. I always get error Input string was not in a correct format. which is strange since code works when 2. and 3. tbs are filled and I'm not inserting string. And I've specified that table allows inserting of null values.
