sql query to replace a blank cell with any text in access 2007 column

Question

I have an access table which has some cells as blank ( no data ) in a particular column.

how i write an sql query to replace a blank cell with any text in access 2007 column

any help appreciated.

i have already tried the sql query

update tableA set colA = 'abc' where ISNULL(colA);

It updates 0 rows.

Answer 1

Update Table
Set [ColumnName] = "my random text"
Where Len([ColumnName]) = 0 OR [ColumnName] Is Null

This will account for situations where the cell value is an empty string or if it is null. If you are trying update one column from another you can do:

Update Table
Set [ColumnName] = [MyOtherColumnName]
Where Len([ColumnName]) = 0 OR [ColumnName] Is Null

Answer 2

Im pretty sure its

update tableA set colA='abc' where colA is null

Answer 3

Try this:

update tableA set colA = 'abc' where colA IS NULL;
