>Subject: [PATCH] Bug 38602: Do not check if columns bookings.creation_date and
> bookings.modification_date from information_schema
>
>If one has multiple databases in use adding columns
>bookings.creation_date and bookings.modification_date is added
>just to first updated database and skipped in other updates.
>This happens because we check if these columns already exist
>in database from information_schema. We should instead make
>this check with method column_exists.
>
>To test:
>1. Apply this patch.
>3. Drop columns bookings.creation_date and bookings.modification_date:
>ALTER TABLE bookings DROP COLUMN creation_date;
>ALTER TABLE bookings DROP COLUMN modification_date;
>2. Revert your database back to version 24.0600028:
>UPDATE systempreferences SET value = "24.0600014" WHERE variable = "version";
>3. Run updatedatabase.pl.
>=> Check that columns were added.
>
>If you happen to have two databases:
>1. Check if you have columns in your bookings table:
>SELECT DISTINCT TABLE_SCHEMA, TABLE_NAME FROM
>INFORMATION_SCHEMA.COLUMNS WHERE COLUMN_NAME IN
>('creation_date', 'modification_date');
>=> Note that columns exist only in one of the databases.
>2. Make sure you're using database missing columns
>from booking table.
>3. Apply this patch.
>4. Revert back to version 24.0600028.
>5. Run updatedatabase.pl
>=> Check that columns were now added to database.
