Hello Daniel, thx for your quick answer. After having failed with db_oracle module, we effectively tried db_unixodbc. But even with unixodbc, we got some strange errors when kamailio tries to do queries including dates in the where clause: Example of an error reported by kamailio: May 2 08:30:14 newvm1 /usr/sbin/kamailio[26298]: ERROR: nathelper [nathelper.c:2089]: nh_timer(): failed to fetch contacts May 2 08:30:15 newvm1 /usr/sbin/kamailio[26298]: ERROR: db_unixodbc [dbase.c:133]: db_unixodbc_submit_query(): rv=-1.

Hello, It is two single quote characters (‘). If I try with one double quote character (“), it also fails. The only way to make it work is to have one single quote character surrounding the date.

Thx Daniel! I will get the code from git. What do I need to recompile? Only unixodbc module? Any other lib? We are using installation done with the official rpm and would like to keep an environment as clean as possible and just change the modified libs. Thx for this quick support.

The usrloc was setting the value for time already quoted and then the db api was quoting again. I guess you were using db-only mode for usrloc. Can you try again with latest git branch 4.4 or master?

Hello Daniel, I patched our kamailio 4.4.0 with the following modified files: lib/srdb1/db_ut.h lib/srdb1/db_ut.c modules/urloc/dlist.c I recompiled and replaced libsrdb1.so.1.0 and usrloc.so.

Hello Daniel, I add a look to the db_unixodbc and the presence modules. To correct the ODBC replace query that is visibly not supported by Oracle, I would like to add a new parameter in the db_unixodbc module : replaceQuery = {0:1}. 0 = not supported, 1 = supported (default). Now, in the presence module, I found this comment : if (pa_dbf.replace != NULL) { if(pa_dbf.replace(pa_db, db_keys, db_vals, n_query_cols, 2, 0) < 0) ... } else { */* If you use insert() instead of replace() be prepared for some * DB error messages. There is a lot of time between the * query() that indicated there was no matching entry in the DB * and this insert(), so on a multi-user system it is entirely * possible (even likely) that a record will be added after the * query() but before this insert(). */* if(pa_dbf.insert(pa_db, db_keys, db_vals, n_query_cols )< 0) What will happen if we do inserts only? Will the table grow? Is there a purge mechanism somewhere? Would it be possible in the replace method to do an update and in case of error, do an insert? What is your opinion?

Hello, on the master branch (development). Then the commits will be backported to stable branches using "git cherry-pick". An important detail is to format the commit log messages as recommended by the guidelines at: - https://www.kamailio.org/wiki/devel/github-contributions#commit_message_for… For example, if you committed to db_oracle module, then the commit message must start like: db_oracle: ...

Hello Daniel, I found the problem: kamctl tool for oracle created a BLOB for the BODY column of table PRESENTITY. I changed it to CLOB and now it works better.

I still have some errors in a query to replace watchers (see below). I'm trying to investigate the problem before boring you with that. Here is the the error I get: Query= replace watchers(presentity_uri,watcher_username,watcher_domain,event,status,inserted_time,reason ) values ('sip:frederic.mathys@ims-nagra.test','giovanni.mele','ims-nagra.test','presence',1,1462195290,'') May 2 15:21:30 newvm1 /usr/sbin/kamailio[560]: ERROR: db_unixodbc [connection.c:220]: db_unixodbc_extract_error(): unixodbc:SQLExecDirect=42000:1:900:[Oracle][ODBC][Ora]ORA-00900: invalid SQL statement#012 I fail to understand where is the where clause of the replace query...
