Replacing null values in a table
Does anyone know a quick way to replace ALL nulls with zeros throughout the table
Thank you for taking the time to report an issue.
What's wrong... Please write below.
My table in its basic form has two fields.
Field A: Client
Field B: Quantity
The data is pulled from elsewhere in the database, but when it extracts it will have the client, and quantities. but some clients will have a Null quantity. e.g. below:
If it returns Null, I want the Null result to be replaced with a zero. I have tried, and tried to make this work, but keep failing
Is function I can make that searches for null values and sets them equal to zero before I run my main program?
I need to convert that field to a date/time one. Which is being hindered by these values of NULL.
The problem is that when I put the word NULL in the field criteria spot, Access believes that I am referring to a value of 'null' and will not do the update.
I have done "NULL", NULL, =NULL, ="NULL", is NULL. and no success.
Please remember that the actual value is not 'null'. It is a text field that has the word NULL in the field.
I tried simply renaming the value but all the records that had already had the incorrectly named version stayed the same.
Is there a way to fix this without going record by record and replacing the erroneously named value with the correct one? That would take forever.
ACCNO Address1 Address2 Address3 Address4 Address5 Postcode
I import it into a table called address which is fine. I then go to put it into another table (customer_register) using an append query but it kicks up a fuss saying it can't do it because of a data validation rule.
I’ve worked out this is because not everybody in the table in excel has full data, for example some people only have three address lines and when appending it to the new table it picks these up as blanks ("") rather than null values (is null) and refuses to do it.
is there any way of replacing these blank cells at import level rather than writing queries that will remove each one?I’m now faced with writing six queries to ensure all blanks are removed from address1,2,3,4,5 and post-code but I’d like a better way.
Now I am looking for a query that can help me update this table to keep all the records as it is and only changing the null values to zero so that adding the other values to zero can give me the desired result
Or (tbl_finaloutput.[Discharge Disposition])<>"PVH Inpt/Outpt")
AND ((tbl_finaloutput.[Patient Type])="er"
I want to make sure I return all Null values in the Discharge Disposition field. For example, there may be another record where the patient type is "er" but the discharge disposition field is blank--this should be in the result because it's an "er" record. I know that I need to define that null values should be recognized as valid, but not sure how
I have a large table that contains NULL values and values like €0,00 in a field with the name price. I need to replace these values with €0,01
So I thought my rusty sql knowledge and google could help me solve this, but I am stuck.
To remove the null values I used the query:
SET tblItem.prijs = "€0,01"
WHERE (((tblItem.prijs) Is Null));
and that worked well to remove the NULL values and changed them to €0,01
00 to €0,01
SET tblItem.prijs = "€0,01"
WHERE (((tblItem.prijs) Is "€0,00"));
But it does not and I am puzzled why. It must be something very obvious that I am overlooking, but what?
