Subject [Roller-JIRA] Resolved: (ROL-1563) Errors in postgres migration script from 3.1 to 4.0
Date Wed, 12 Sep 2007 14:41:28 GMT

     [ http://opensource.atlassian.com/projects/roller/browse/ROL-1563?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

David Johnson resolved ROL-1563.
--------------------------------

    Resolution: Fixed

See commit: http://svn.apache.org/viewvc?rev=574968&view=rev

1) Postgres doesn't like drop index on syntax
- Added Postgres to special cases in #dropIndex() macro

2) Postgres doesn't allow you to use alias name the set column of update
- Added special case for Postgres so alias is not used in that update

3) Boolean values were not properly quoted
- Use $db.BOOLEAN_FALSE and $db.BOOLEAN_TRUE to ensure that Posgtres gets true and false instead
of 1 and 0.

> (From Adib Saikali)
> I downloaded the roller 4.0 rc1 and discovered that the upgrade scripts from
> roller 3.1 to 4.0 were not working, they had a few syntax errors.
> I encountred three tyes of errors.
> 1) various drop index statements were of the form "drop index xyz on table"
> those had to be changed to
> "drop index xyz" the on table part of the syntox did not work with postgres
> 8.2.4
> 2) a udpate statement on weblog entry was of the form update weblogentry e
> set e.coulmname ... Etc postgres does not allow you to use the alias name on
> the set column so I had to drop the e. from the update statement
> 3) various update statements where clauses did not work because boolean
> values were not properly quoted, changes were of the form column=1 to
> column='1'
> I made the chages to the script to get to execute with psql without erros,
> hopefuly there is nothing missing from the script.
