Thanks Daniel,  I just needed to cast the NULL before returning  it from my MySQL function.

 

cast(NULL as unsigned integer)

ok, good hint. I guess MYSQL_TYPE_NULL is returned as type for such cases -- I assume the type is not a valid one to define columns, but used for returned values from functions and procedures, also probably for views with columns defined null always.

It may be an option to map internally in db_mysql module the MYSQL_TYPE_NULL to integer type -- the value should have the null flag set as well.

Cheers,
Daniel

Hello,

 

I thought I’d post this again just in case anyone has some suggestions.   Apologies if this is a basic question!!

 

We are using Kamailio 3.1.5 in production.  We use the sqlops module to run a mysql function to return parameters.   In the logs I am seeing the flowing warnings.  

 

/usr/sbin/kamailio[3991]: WARNING: db_mysql [km_res.c:143]: unhandled data type column (diallednumber) type id (6), use DB1_STRING as default

/usr/sbin/kamailio[3991]: WARNING: db_mysql [km_res.c:143]: unhandled data type column (ringtime) type id (6), use DB1_STRING as default

 

 

I think these are generated when we return a null value,  although this is not causing us a problem can anyone advise how to eliminate these warnings.

what are the definitions of the columns diallednumber and ringtime in the database table?

The log message is not related to value, but to the column's data type, which is not recognized by db_mysql, thus the value is stored as string in the result array.

Cheers,
Daniel
