Hi,
What i have done is created a custom JDBC plug-in subclass of the
default MySQLPlugIn that generates the correct sql. I based mine off the
PostgreSQL plug-in in Project WOnder. From memory, i didn't have to
change much and everything just works.
Give that a go and let me know if you need help.
I have thought about contributing this back to WOnder but i need
permission to do that first. Unfortunately, i can't contribute that
until i get that permission.
Regards
Peter

Hi,
You probably should try using left outer join for the relationship,
although we had no luck with it for MySQL. Looks like the EOF sql
generation doesn't support outer joins with MySQL.
The same problem is discussed here:
http://wodeveloper.com/omniLists/eof/2002/October/msg00005.html
I would also really like to hear what is the recommended solution to
this problem.
Denis.

Has anyone got a generic search qualifier construction utility method
that takes an array of key/keyPaths of text attributes to search, a
search term and will take into account that some objects in the
keyPath relationships may be null. A simple EOOrQualifier of
EOKeyValueQualifiers does not do it for the simple reason that null
relationships on the keypaths get excluded as a result of the SQL
generated.
For example, here is an array of key/keypaths to search (using * +
searchTerm + * and an EOOrQualifier from array of
EOKeyValueQualifiers with case insensitive like on keys/keypaths:
contactFirstName,contactLastName,emailAddress,traderCode,businessName,ownerUser.firstName,ownerUser.lastName,ownerUser.emailAddress,ownerUser.comment,address.street1,address.street2,address.city,address.state,address.zip
The address and ownerUser relationships are optional, so a term that
matches the traderCode attribute for example will not select the
object of the ownerUser is null, but will if ownerUser is not null.
The SQL generated using simple EOKeyValueQualifier array and
EOOrQualifier is like this for the example above and the final 'AND
t0.oidowneruser = T1.oid' obviously excludes records where
t0.oidowneruser is null:
SELECT t0.businessname, RTRIM(t0.cellphone), t0.contactfirstname,
t0.contactlastname, t0.contacttitle, t0.defaultcommission,
t0.defaultfixedamountcommission, t0.emailaddress, t0.enddate,
RTRIM(t0.fax), RTRIM(t0.isnotificationson), t0.oid, t0.oidaddress,
t0.oidowneruser, t0.oidreseller, RTRIM(t0.phone), t0.recaddtime,
t0.recadduser, t0.recmodtime, t0.recmoduser, t0.startdate,
t0.tradercode, t0.type FROM trader t0, address T2, usr T1
WHERE (t0.type = 20 AND (UPPER(t0.contactfirstname) LIKE
UPPER('%CBUF%') ESCAPE '|' OR UPPER(t0.contactlastname) LIKE
UPPER('%CBUF%') ESCAPE '|' OR UPPER(t0.emailaddress) LIKE
UPPER('%CBUF%') ESCAPE '|' OR UPPER(t0.tradercode) LIKE
UPPER('%CBUF%') ESCAPE '|' OR UPPER(t0.businessname) LIKE
UPPER('%CBUF%') ESCAPE '|' OR UPPER(T1.firstname) LIKE
UPPER('%CBUF%') ESCAPE '|' OR UPPER(T1.lastname) LIKE UPPER('%CBUF%')
ESCAPE '|' OR UPPER(T1.emailaddress) LIKE UPPER('%CBUF%') ESCAPE '|'
OR UPPER(T1.comment) LIKE UPPER('%CBUF%') ESCAPE '|' OR
UPPER(T2.street1) LIKE UPPER('%CBUF%') ESCAPE '|' OR
UPPER(T2.street2) LIKE UPPER('%CBUF%') ESCAPE '|' OR UPPER(T2.city)
LIKE UPPER('%CBUF%') ESCAPE '|' OR UPPER(T2.state) LIKE
UPPER('%CBUF%') ESCAPE '|' OR UPPER(T2.zip) LIKE UPPER('%CBUF%')
ESCAPE '|')) AND t0.oidaddress = T2.oid AND t0.oidowneruser = T1.oid;
Anyone done this already and has code to share please?
