How to replace blank null values with 0 for all records

Question

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

I would change the SQL statement above to be more generic  Using wildcards is never a bad idea when it comes to mass population to avoid nulls    Try this   Update Table Set     0 Where   Is Null

I used a two step process to change rows with  blank  values to  Null  values as place holders     UPDATE  TableName  SET  TableName   ColumnName     0  WHERE     TableName   ColumnName          UPDATE  TableName  SET  TableName   ColumnName     Null  WHERE     TableName   ColumnName    0

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
