<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">We are using OTP18.3 on Centos towards a MySQL database using ODBC. When switching a column to LONGTEXT, ODBC type SQL_LONGVARCHAR, we noticed that the values were chopped off when reading from Erlang.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">Reading odbcserver.h and odbcserver.c in the erlang distribution this was no surprise, as the ‘size’ variable is set to MAXCOLSIZE (=8001).<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">Increasing this define and recompiling the odbcserver fixed the limitation. Has anyone else experienced this limitation, and perhaps come up with a better solution? The solution feels wrong, since the maximum value of
a LONGTEXT is rather big, and you do not want to malloc 4GB of memory for each LONGTEXT column.<o:p></o:p></span></p>
