Ms sql invalid use of null

My problem starts when I link the two tables, and as stated, it runs, but i can't scroll through all the data. Can you help me understand the context or how to correct? I've read some of the messages about this message, but I can't understand how they apply to my situation. I cannot change the data tables corporate table , I can only try to fix the queries.

The problem sounds like one of the columns allows null values or they both do. While cstr function will convert the number to a string, the function will error out if the column has a null value cstr function does not work on null columns.

So, you have to use a expression that converts the empty null to some string. This type of join will run quite slow. I would perhaps ask the server guy if a view of the joined tables can be created for you.

You would then link to that view and it would eliminate the need for the ctstr in those joins, and in fact you would not need to create the join either. It won't stop the code to tell you which one is having a problem. However, if you use a very specific default value, then you should be able to tell which ones were assigned the default value. To clarify what I said above about assigning a specific default value.

If you assign a value which will "never" occur in your data set, then you can easily spot them on your report. I can't find rstOutput.

Update in the code you posted earlier. This line must be in another function. We also suggest that you could upload your database file on OneDrive, it will help other partners can either share their knowledge and resolve your issue or learn from your interaction with us.

Close 'DoCmd. Quit Application. Thank you, Jessica. Monday, September 12, PM. Thank you so much to everyone for all your help. And especially DBGuy Friday, September 16, PM. Hi Jessica, When you get the error and if you're given a choice to debug the code, click on the Debug button and let us know which like gets highlighted. Hope it helps Tuesday, September 13, AM. Tuesday, September 13, PM. Thanks, Jessica. But still, as I was asking earlier, what do you want leaseDue to be if leaseMonths or ShipDate is empty?

Hi Jessica, Based on what you just posted, the only question left is what happens if there is no ShipDate available? Is there a way to find where that is coming from? Hi Jessica, The code does not know what to do when there is no ShipDate because you haven't told it what to do when there is no ShipDate. Or am I missing something Hi Jessica, I know it can get confusing. That does help a lot. I am beginning to understand it all better.

Hi Jessica, ShipDate is an argument of the function. I found this in that query Spacing does matter in coding, right? Hi Jessica, I would just like to repeat you originally came here because you had a problem with an error about a Null value. Just my 2 cents I love your 2 cents!!

How could I share a sample copy? I would happily do that to get this solved. Thank you so much for your patience with me and for helping. Not the DLookup. The CDate I meant. Hi Jessica, You're welcome. My email address should be in my profile or my website. If you can't find it, let me know.

Thank you so much. I will make a copy and get it over to you. I tried it but i don't know if I did it right. I have default constraints in my database. I want to update all of the columns with a default value to not allow NULLs. Dear folks, please tell me the query for altering a column from not null to null Vinod. Is there any way to achieve this I have a table, which is a "customers" table.

I have a stored procedure which takes in parameters name, address, password etc I've always done this, and works great. Now, this works fine locally. I've even dropped and recreated the stored procedure but makes no difference. Any ideas why? I have a pivot transform that pivots a batch type.

After the pivot, each batch type has its own row with null values for the other batch types that were pivoted. I want to group two fields and max the remaining batch types so that the multiple rows are displayed on one row.

I tried using the aggregate transform, but since the batch type field is a string, the max function fails in the package. Is there another transform or can I use the aggragate transform another way so that the max will work on a string? Hello everyone,I have a table that stores data of a Person. For personal data, there are 2 different fields, for example My question is, i would like to know if it's possible to make it for at least one of these fields to be NOT NULL, but not necessarily both.

I dont care which one is filled in, as long as ONE is filled in Thanks in advance,SuperJB. Hello all I am trying to run a sql statement, without having to run stored procedures , that will lookup a value stored in a Record.

I have a field tied to a Microsoft Access form - ItemLocation. If the user selects a unique ItemLocation the report will attempt to locate all values within that ItemLocation.

If the user decides to leave the field blank, I would like for it to return all values for every ItemLocation. If anyone can help, I would really appreciate it. I will attach code.

My problem is the last line of this SQL statement. ITemLocation is null, I get no data. I would like for it to return everything. Thank you. BarCodeID, A. ItemDescription, A. ItemCategory, A. TypeOfItem, A. SerialNumber, B. ItemLocation, B. LocationID, B. LastUpdate, B. TrackItID, B. Is there any way in SQL Server 6. None of the values in this column contain null values. I need to add a primary key constraint on the column for replication purposes and SQL won't let me because the column is nullable.

The table has got records. Thanks in advance, Srini.
