Cheers,

Did not work. Same symptoms as before.
I see that the file modules/db_unixodbc/connection.h defines a strn
structure with a hardcoded limit of STRN_LEN=1024 bytes per field.

I have solved this issue. In order to make it work with unixodbc, I
need to apply the attached patch. This patch removes the hardcoded
1024-byte limit for field data that exists in current kamailio-4.1.3.
What the patch does is replace the embedded array in the 'struct
strn' with a pointer and a field for allocated size. The patch also
introduces three functions for manipulation of the modified 'struct
strn'. When the SQLGetData function returns SQL_SUCCESS_WITH_INFO,
the SQLSTATE is queried for the "data truncated" method. Then the
rest of the data is fetched in a loop.
Please review this patch for inclusion. The actual detection of the
truncation could need some work.
Also, the ODBC implementation could trip on true binary data
(containing embedded binary zeroes) because it is not binary-safe.
Are there scenarios in which the rest of Kamailio might need to
retrieve or store data with a binary-safe implementation?
How should I proceed to
submit this patch for inclusion to the git
repository?
