Don't matter if all the fields are null.

If you don't have this table you must create the table with this command:

This command is for Oracle DB

CREATE TABLE umpAlarmAnnotations (
nimid VARCHAR2(50) DEFAULT NULL,
created date DEFAULT NULL,
username VARCHAR2(64) DEFAULT NULL,
annotation VARCHAR2(1024) DEFAULT NULL,
alarmSource VARCHAR2(50) DEFAULT NULL) 

For the Microsoft SQL

CREATE TABLE umpAlarmAnnotations (
nimid VARCHAR(50) DEFAULT NULL,
created date DEFAULT NULL,
username VARCHAR(64) DEFAULT NULL,
annotation VARCHAR(1024) DEFAULT NULL,
alarmSource VARCHAR(50) DEFAULT NULL) 

If you have the table please just execute this command to adjust the columns size:

For Oracle DB:

ALTER TABLE umpAlarmAnnotations MODIFY nimid VARCHAR2(50);

ALTER TABLE umpAlarmAnnotations ADD alarmSource VARCHAR2(50);

UPDATE umpAlarmAnnotations SET alarmSource = 'NAS';

For Microsoft DB:

ALTER TABLE umpAlarmAnnotations alter column nimid VARCHAR(50);

ALTER TABLE umpAlarmAnnotations ADD alarmSource VARCHAR(50);

UPDATE umpAlarmAnnotations SET alarmSource = 'NAS';
