Modifying existing tables in sqlCVS is a multistep process which involves manually executing stuff on the sqlCVS main server (schema.linuxmce.org as of this writing). The current master database is main_sqlcvs.

On the main sqlCVS server

Add the modification statement to psc_<repo>_schema

For example, to add a new field FK_Text to the CommandGroup table in the local repository, the command is

insert into psc_local_schema set Value= "ALTER TABLE `CommandGroup` ADD `FK_Text` INT(11) DEFAULT NULL AFTER `TemplateParm2`";

Update the psc_<repo>_repset table

After adding the above alter statement to the schema, we need to update table rep_set with the latest psc_id created by the above statement

UPDATE psc_local_repset SET Value=(Select max(psc_id) From psc_local_schema);

Modifying the actual table

Now we modify the actual table, by executing the ALTER TABLE command in the main_sqlcvs database

ALTER TABLE `CommandGroup` ADD `FK_Text` INT(11) DEFAULT NULL AFTER `TemplateParm2`;

On the local system

To update the schema on our system, we need to run the dump command locally

/usr/pluto/bin/sqlCVS -H schema.linuxmce.org -R 3999 -r local dump

Notes

If anyone knows of a simpler approach, please amend. Thanks.
