Problem sending query that contains § char

[RiccardoFrancescato]

Hi,
I have a problem running querys that contains char §.
The DB2 instance contins table with column names that contains § char for example CLM$§1.
when i try to execute the query the following query, laravel returns sql error

 DB::connection('ibmi')
    ->table('ST3SFA.TSTCLM$F')
    ->selectRaw('
        TRIM(CAST(CLM$§1 AS VARCHAR(255))) AS id
        ,TRIM(CAST(CLM$02 AS VARCHAR(255))) AS description
        ,TRIM(CAST(ECLM05 AS VARCHAR(255))) AS super_calss_id
        ,CASE WHEN TRIM(CAST(CLM$96 AS VARCHAR(255))) = \'\' THEN CAST(NULL as VARCHAR(255)) ELSE CURRENT_TIMESTAMP END AS deleted_at
    ')
    ->orderByRaw('TRIM(CAST(CLM$§1 AS VARCHAR(255)))')
    ->chunk(10, function ($lines) {
        foreach ($lines as $line) {
            $result = [
                'id'=>ucfirst(strtolower($line->id)),
                'description'=>ucfirst(strtolower($line->description)),
                'super_calss_id'=>ucfirst(strtolower($line->super_calss_id)),
                'deleted_at'=>$line->deleted_at,
            ];
            dump($result);
       }
    });

Error:

Illuminate\Database\QueryException
SQLSTATE[42000]: Syntax error or access violation: 0 (SQLPrepare[0] at /builddir/build/BUILD/php-7.3.14/ext/pdo_odbc/odbc_driver.c:204) (SQL: select TRIM(CAST(CLM$§1 AS VARCHAR(255))) AS id ,TRIM(CAST(CLM$02 AS VARCHAR(255))) AS description ,TRIM(CAST(ECLM05 AS VARCHAR(255))) AS super_calss_id ,CASE WHEN TRIM(CAST(CLM$96 AS VARCHAR(255))) = '' THEN CAST(NULL as VARCHAR(255)) ELSE CURRENT_TIMESTAMP END AS deleted_at from ST3SFA.TSTCLM$F order by TRIM(CAST(CLM$§1 AS VARCHAR(255))) FETCH FIRST 10 ROWS ONLY)

I have tried to enable 'UNICODESQL' => 1, and 'DEBUG' => 65536, in the cfg but without success.
If i try to execute the same query wituout specifying column names and using the *

DB::connection('ibmi')
    ->table('ST3SFA.TSTCLM$F')
    ->selectRaw('*')
    ->get();

the result is returned but the colun is not accessible sing it contains $ in the name.
Anyone has faced this kind of problem before?
Thanks in advance
Riccardo

Hi, I have the same problem with (Ñ) character, my temporal solution is add utf8_decode(COLUMN) in my where method:

Wodetal2::where('WDSERV','BAS')
->where(utf8_decode('WDCURÑ'),'2')
->where('WDMRC$','>',0)
->get();

i think this is a problem with driver, in other librarys like adodb php i have to do the same utf8_decode in my sql instrucction to work.

if you have a other best solution i want to know.
