UPDATE  TableName  SET  ColumnName    Replace  ColumnName     StringToRemove      Replacement      In your instance it would be  UPDATE  TableName  SET  ColumnName    Replace  ColumnName     StringToRemove          Because there is no replacement  you want to get rid of it    This will run on every row of the specified table  No need for a WHERE clause unless you want to specify only certain rows

Use the  REPLACE  string function on the column in question   UPDATE  yourTable  SET YourColumn   REPLACE YourColumn           WHERE  your conditions    Replace the     with the character you want to strip out and specify your WHERE clause to match the rows you want to apply the update to   Of course  the REPLACE function can also be used - as other answerer have shown - in a SELECT statement - from your question  I assumed you were trying to update a table   Marc
