MS Access: How to replace blank (null ) values with 0 for all records?
I guess it has to be done using SQL. I can use Find and Replace to replace 0 with blank, but not the other way around (won't "find" a blank, even if I enter [Ctrl-Spacebar] which inserts a space.
So I guess I need to do SQL where I find null values for MyField, then replace all of them with 0.

UPDATE [table] SET [column]=0 WHERE [column] IS NULL; Null Values can be replaced in SQL by using UPDATE, SET, and WHERE to search a column in a table for nulls and replace them. In the example above it replaces them with 0.
The ISNULL Function is a built-in function to replace nulls with specified replacement values. To use this function, all you need to do is pass the column name in the first parameter and in the second parameter pass the value with which you want to replace the null value.
All options will replace NULL data with zeros. Options 3, 4, and 5 will replace missing data with zeros. Options 2, 3, and 4 will replace filtered out data with zeros. It may be possible to show additional rows/columns in the view with the Analysis > Table Layout > Show Empty Rows/Columns option; However, no data can be written into these rows.
Because if any parameter of Replace function is null then it returns only NULL. It can be advisable to use NULLIF (columnName, ''). It is replacing all values to null. declare @Blank nvarchar (1)='' SELECT nullif (COLUMN1,@Blank) FROM Orders; Its select all COLUMN1 records as null if thay are blank.
NULL data: this occurs when the underlying data set contains records but the measure value (s) is NULL or blank. In the attached Excel workbook, "NULL and Missing Examples.xlsx", the project "Brosnya" is NULL for "In-Progress" and "Completed". Missing data: this occurs when there are no records in the underlying data set.
IFNULL function can also be used to replace NULL values with another value. It simply checks if the value of its first argument is NULL, so it will be replaced by the value of the second argument. SELECT IFNULL(Age, '0') AS Age FROM Clients;
Go to the query designer window, switch to SQL mode, and try this:
Update Table Set MyField = 0
Where MyField Is Null;
If you're trying to do this with a query, then here is your answer:
SELECT ISNULL([field], 0) FROM [table]
Edit
ISNULL function was used incorrectly - this modified version uses IIF
SELECT IIF(ISNULL([field]), 0, [field]) FROM [table]
If you want to replace the actual values in the table, then you'll need to do it this way:
UPDATE [table] SET [FIELD] = 0 WHERE [FIELD] IS NULL
without 'where's and 'if's ...
Update Table Set MyField = Nz(MyField,0)
