Parameter Value From Empty Text Box - Null Or 0 Length?

Jul 20, 2005

Hi,
I run a stored procedure with a parameter given from a text box in an access
adp. If the text box is empty then what is passed to the parameter? I can't
seem to get it to flag up as either null, or 0 length.

Any tips?
Cheers,
Chris

Setting Empty Text Box Input On Form To Null Parameter For Sql

Feb 19, 2007

Hi,
 I'm pretty new to ASP.NET and VB, but I'm working on a project which is essentially a staff directory. Using VS 2005, I've setup a basic grid view which connects to an object which connects via a data layer to a SQL database with Name, Surname, Email, Extension No and Department fields.
I have it working so that if a user enters a name and surname for example, it will return all records with either the name matching or surname matching input parameters. What I want to do is to set up a SQL query which is:
 SELECT * FROM records WHERE (Name LIKE @Name) AND (Surname LIKE @Surname) AND (Email LIKE @Email) AND (Dept LIKE @Dept)
so that if the user only enters the first name and surname for example as above, it ONLY returns the record which matches the first name and surname and not all records with either/or. One way I've thought of to do this is to convert the empty fields to "Nothing" so that it fullfils the search parameter for the empty fields. If someone can explain how to do this, or can suggest a better way, I'd be grateful.
Cheers,
Tom

Anyway To Check If A Text Field Is Blank (not Null But Just A Empty String '') ?

Oct 27, 2004

i have a trigger on a table right now... when fields are inserted, theres a text field inserted and i want to check if that text field = '' (the empty string, not NULL) and if it doesn't equal that, then perform some row updates on other tables, but if it is empty, to not do anything else in the trigger... right now i have this:


Code:


IF ((SELECT Note FROM XATPoDetail WHERE ReqNbr = (SELECT ReqNbr FROM Inserted)) LIKE(''))



Note is the text field, XATPoDetail is the table where its being inserted into. I had to do the select FROM the table because it wouldn't let me select a text data type from the "Inserted" virtual table

but it tells me me "Error 279: The text, ntext, and image data types are invalid in this subquery or aggregate expression"

thanks

Empty &&<&&> IS NOT NULL

Jul 22, 2007

Hello,



I have a query that returns the appropriate values I need, however there is one field I'd like to add and utilize but my problem is I only want to use it if it contains data.



If I filter it with IS NOT NULL it returns all the records, including the empty records. The field is simply empty, and doesn't come back as NULL. If I filter it with =' ' , it shows all the records with the empty records only.



I need to do the opposite, be able to filter it only if it's not empty.



Any help would be appreciated.

Any help please?

Thanks!

COALESCE: Empty Instead Of NULL?

Mar 25, 2008

I've inherited a terribly designed database. When cells in the tables have nothing in them, rather than being NULL, they're just empty. So now I can't use COALESCE...

Is there a way for COALESCE to check if a cell is empty instead of NULL? And if not, is there a way to get around this?

Well met,

Let's say I have a web form that allows users to insert and update records in a SQL database. Is it better to set empty web controls (textbox, etc.) to DBNull or let it go as an empty string into the database?

Example code:

if (tboxNAME.Text == "")
{
sqlCommand1.Parameters["@NAME"].Value = DBNull.Value;
}
else
{
sqlCommand1.Parameters["@NAME"].Value = tboxNAME.Text;
}

Is the above overkill? It seems like it would be a good idea to set fields which the user empties back to Null rather than an empty string.

Thanks,

-Tony

HELP : Empty String To Null Conversion By SQL

Nov 10, 2005

Hi folks,

I've have about 100 tables, for some reasons, column values that are originally NULL was inserted as emtpy string. So, I am wondering if I can write JUST ONE SQL (hopefully don't have to specify the field names in the SQL as well) for each table so that all the empty strings will be converted back to NULL.

THANKS JOHN

T-SQL (SS2K8) :: Field Has No Value But Is Not NULL Or Empty?

Aug 13, 2015

I added a new field to an existing ETL process which uses SSIS to ingest a CSV file. The new field in the file, Call_Transaction_ID, will not always be populated for every record and so can be NULL or empty for certain records.

Here's the problem:After the file is extracted into a staging table, the Call_Transaction_ID field is showing blank or empty when it has no ID for that particular record. The problem is when I try to then ETL this data into a fact table - I'm trying to set the Call_Transaction_ID field to -1 if it is NULL or empty, however SQL Server doesn't see the field as empty even though there is no value in the field so -1 will NEVER return.

Using a WHERE DATALENGTH(Call_Transaction_ID) = 0 returns 0 records, again because SQL Server doesn't see the field as empty or NULL.

What do I do now to get around this? How do I fix it?

The sum of those two is zero, but the cube get messed but by thousands of zero.

Subscription Issue With Null Default Parameter - Key Cannot Be Null

May 3, 2007

I have a report that is run on a monthly basis with a default date of null. The stored procedure determines the month-end date that it should use should it be sent a null date.

The report works fine when I tell it to create a history entry; however, when I try to add a subscription it doesn't appear to like the null parameter value. Since I have told the report to have a default value of null it doesn't allow me to enter a value on the subscription page.

Now, I suppose I could remove the parameter altogether from the stored proc, but then the users would never be able to run the report for a previous time period. Can someone explain to me why default values aren't allowed to be used on subscriptions when they seem to work fine for ad hoc and scheduled reports? This is really quite frustrating as most of my reports require a date value and default to null so that the user doesn't have to enter them for the latest data.



An internal error occurred on the report server. See the error log for more details. (rsInternalError) Get Online Help




Key cannot be null. Parameter name: key

SQL Server 2014 :: NULL And Empty Strings

Oct 29, 2015

I have always (or at least intended to) treat NULL and empty strings separately in my SQL querying history. Now I have run across something that mystifies me (but probably shouldn't) that I would like an explanation for.

Consider this bit o' code:

DECLARE @ORDER CHAR(10)
SET @ORDER=
(
SELECT NULL
)
IF @ORDER <> ''
PRINT 'Not an empty string'

IF @ORDER IS NULL
PRINT 'It is NULL'

Run this and you will get:

It is NULL

I was expecting:

Not an empty string
It is NULL

Why is NULL not passing the 'not an empty string' test? In other words, how does NULL = '' ? Is NULL cast to an empty string for this comparison?

Web Service Dataset With Null Or Empty Spaces.

Sep 6, 2007

HI,
I am using XmlDataDocuments returned by webservices and query in the reports to populate the reports.

The issue I have is if the dataset used to populate the XML document has any nulls or empty spaces in any field the whole column or row is missing in the data generated by my query in the Reports. Sometimes the whole data is not being returned to the reports.

Sample query I use

<Query>
<SoapAction>http://xxxx.webservices.org/SelectReportRegisters</SoapAction>
<Method Namespace="http://xxxx.webservices.org/" Name="SelectReportRegisters">
<Parameters>
<Parameter Name="p_registerType">
<DefaultValue>All</DefaultValue>
</Parameter>
<Parameter Name="p_registerName">
<DefaultValue>All</DefaultValue>
</Parameter>
<Parameter Name="p_asOfDate">
<DefaultValue>7-1-2009</DefaultValue>
</Parameter>
</Parameters>
</Method>
</Query>

I have tested the webservice with sample data and it works well, returns data.

I use the ISNULL() in my stored procedures to avoid nulls but with empty strings, replacing them with a default value in the managed code is expensive and slows down the reports.
Is there some feature I am missing because of which nulls and empty strings are causing this problem.

I am using Reporting services 2005.

Any pointers will be truly appreciated.
