The code generating that trace message is in DBI.xs which I believe it used by all C DBDs.

    /* --- dispatch --- */

    if (!keep_error && !(*meth_name=='s' && strEQ(meth_name,"set_err")
+)) {
        SV *err_sv;
        if (trace_level && SvOK(err_sv=DBIc_ERR(imp_xxh))) {
            PerlIO *logfp = DBILOGFP;
            PerlIO_printf(logfp, "    !! %s: %s CLEARED by call to %s 
+method\n",
                SvTRUE(err_sv) ? "ERROR" : strlen(SvPV_nolen(err_sv)) 
+? "warn" : "info",
                neatsvpv(DBIc_ERR(imp_xxh),0), meth_name);
        }
        DBIh_CLEAR_ERROR(imp_xxh);
    }
    else {      /* we check for change in ErrCount during call */
        ErrCount = DBIc_ErrCount(imp_xxh);
    }

It is in the despatch code. I /think/ its purpose is that any call to a new method other than set_err clears any previous error/warning/informational error state. 2000 may not be an error - it may be a warning (have you PrintWarn and warnings set) or it may be an informational message which don't get printed at all - you have to go out of your way to get those. Some DBI methods can return true but when tested the return is actually 0E0 and this indicates an informational - read the DBI docs on that.

Without knowing the driver it is impossible to guess what 2000 is.
