  If a record returns null for a particular field I would like to insert -1 into that row.  How is this done?

   

  Select * from aTable where aField = 'aValue'

  afield may have aValue in every row but bField will have null in many rows.  I would like to insert -1 into those rows.

   

   

  Thank you for any assistance

  After You have completed this task you will want to set the column to NOT NULL, and perhaps DEFAULT = -1.

  ALTER TABLE myTable ALTER COLUMN myColumn INT NOT NULL

  ALTER TABLE myTable ADD CONSTRAINT DF_myColumn_MinusOne DEFAULT(-1) FOR myColumn

  Or just in EM.
