ORA-12704: character set mismatch

Post by skoub » Wed 13 Jun 2012 19:00

hi!

i was using dotConnect for Oracle v6.50.237 with CodeFirst without any problems. Today, we have upgraded our project to v7.0.17 and now we get the error ORA-12704: character set mismatch.

I'm not sure where the problem come from but here's my research so far:

Here's the query that throw the 'character set mismatch' error:

Code: Select all

var q = from publication in this.appContext.Publications
            .Include(x => x.Transactions)
            .Include(x => x.PublicationsCommandes)
        select publication;

q.ToList();
If i test each entities one by one, everything is fine:

Code: Select all

this.appContext.Publications.ToList();
this.appContext.Transactions.ToList();
this.appContext.PublicationsCommandes.ToList();
If i remove one Include in the query, everything is fine:

Code: Select all

var q = from publication in this.appContext.Publications
            .Include(x => x.Transactions)
        select publication;

q.ToList();

// OR

var q = from publication in this.appContext.Publications
            .Include(x => x.PublicationsCommandes)
        select publication;

q.ToList();
So the problem is the 2 Includes at the same time. Here's the SQL generated by the query that throw the error:

Code: Select all

Is it a bug on your side or did i miss something on my side?

thank you for the help!

The config.CodeFirstOptions.UseNonUnicodeStrings configuration option (default value is False) is added in order to treat string properties without an explicitly specified server data type, as non-unicode.

We will post here when the corresponding public build of dotConnect for Oracle is available for download.
