ORA-12704: character set mismatch Table-Per-Type inheritance

ORA-12704: character set mismatch Table-Per-Type inheritance

Postby nicolas.bourgoin » Mon 08 Jul 2013 16:44

Using dotConnect for Oracle 7.7.276.6 and Entity Framework 6.0 beta1, I am trying to fetch some data from oracle database 10g Enterprise Edition Release 10.2.0.4.0

Schema (simplified)
Job HasMany Elements (which can be cable or terminal)

Cable is an element.
Terminal is an element.

This is setup using table per type inheritance.

Goal: Query a job and include all its elements.

If I remove completely Cable from my project, the query will run fine and include all the terminals related. The same applies if I remove Terminal completely from my project: The query will run fine and include all the cables related.

When I include both and try to run the query, I get a "ORA-12704: character set mismatch" error.

Please refer to http://forums.devart.com/viewtopic.php?t=23267.

If this doesn't help, send us a small complete test project with the corresponding DDL/DML script of database objects to reproduce the issue in our environment.

Re: ORA-12704: character set mismatch Table-Per-Type inheritance

Postby nicolas.bourgoin » Wed 10 Jul 2013 14:20

After digging throught the issue, I found it had nothing to do with table-per-type inheritance.

Putting in my mappings for string VARCHAR2 columns:

Code: Select all
Property(t => t.FIBER_MODE).HasMaxLength(8).HasColumnType("VARCHAR2")


was not enough to make dotConnect understand that the column type is a VARCHAR2. Therefore, it tried to cast in SQL as "TO_NCHAR". The workaround was to specify that the column is not unicode:

Code: Select all
Property(t => t.FIBER_MODE).IsUnicode(false).HasMaxLength(8).HasColumnType("VARCHAR2");


And it now correctly cast to VARCHAR2 in SQL using: "TO_CHAR"
