In MS-Access database, table called NewTable3
colname is a text column containing lot of empty cells or blanks.
i want to put ? character in empty cells . when i run the query
UPDATE NewTable3 SET colname = '?' WHERE ISNULL(colname) ;
This query updates 0 records why . what is wrong with this query
Two quick things:
1) Try putting the colname in square brackets.
2) Remember that empty cells (Nulls) and empty strings (“”) are different.
Together:
Also, are you running the query in Access itself, or just using the Access engine and using the data in another program/via a VBA script? It can make a difference.
