CASE WHEN P.NURSING_UNIT is not null THEN P.NURSING_UNIT ELSE '' END NURSING_UNIT
    ,CASE WHEN P.UNIT_CODE is not null THEN P.UNIT_CODE ELSE '' END UNIT_CODE, 
    CASE WHEN M.SIGN_DATE IS NOT NULL THEN 'COMPLETED' ELSE 
    WHEN M.SIGN_DATE IS NULL THEN 'UNCOMPLETED' AS ASSESSMENTS

error: because the sp is not compiling now. getting this error message:

Standard SQL:

COALESCE(P.NURSING_UNIT, '') AS NURSING_UNIT, 
COALESCE(P.UNIT_CODE, '') AS UNIT_CODE, 
CASE 
   WHEN M.SIGN_DATE IS NULL THEN 'UNCOMPLETED' 
   ELSE 'COMPLETED' 
END AS ASSESSMENTS

If your vendor provides a REPLACE() function:

COALESCE(P.NURSING_UNIT, '') AS NURSING_UNIT, 
COALESCE(P.UNIT_CODE, '') AS UNIT_CODE, 
COALESCE(REPLACE(M.SIGN_DATE, M.SIGN_DATE, 'COMPLETED'), 'UNCOMPLETED') AS ASSESSMENTS
