describe table from oracle to mysql shows wrong data type

[General Info]

Hi

I have upgraded mysql odbc in a server where Oracle 19c is running, we use this ODBC to access a remote MYSQL database. The ODBC driver installed is 8.0.31.

The developers noticed that when describe table we see different behaviour compare with previous ODBC which was 5.3.6.



ODBC 5.3.6
SQL> desc "lecturas"@mysql_t
Name Null? Type
----------------------------------------- -------- ----------------------------
idSim NOT NULL NUMBER(10)
idAlfresco NOT NULL VARCHAR2(65 CHAR)
nombre NOT NULL VARCHAR2(60 CHAR)
descripcion VARCHAR2(500 CHAR)
bloqueado CHAR(1 CHAR)

ODBC 8.0.31
SQL> desc "lecturas"@mysql_t
Name Null? Type
----------------------------------------- -------- ----------------------------
idSim NOT NULL NUMBER(10)
idAlfresco NOT NULL VARCHAR2(780)
nombre NOT NULL VARCHAR2(720)
descripcion LONG
bloqueado CHAR(12)



Anyone have observer this behaviour change?
