Using Parameters in SQL-Query not only in where clauses

Question

Hi,
I try to use Publisher parameters in the SQL Query from a Data Set.
All of them have default values.
So far, this is no problem, unless I try to use such a parameter value as an ordinary attribute value:
>
select
     case when (:pv_Group = 'no') then "DM15D_BETRIEBSTEIL"."BETR_TEIL"
                                        else :pv_some_Text end                                                                  as Betr_Teil,
     case when (:pv_Group = 'no') then "DM15D_BETRIEBSTEIL"."SUVA_NR_FORM"
                                        else :pv_some_Text end                                                        as Suva_Nr,
     case when (:pv_Group = 'no') then "DM15K_RIS_FAKTEN_PRO_BTT_JHR"."RIS_VOLLBESCH"
                                        else sum("DM15K_RIS_FAKTEN_PRO_BTT_JHR"."RIS_VOLLBESCH") end      as Vollbesch
from "GDWH05"
where
     "DM15D_BETRIEBSTEIL"."SUVA_NR_FORM" in (:pv_nim100)
     fetch first 65001 rows ONLY
>
The parameters 'pv_Group' and 'pv_nim100' are working fine. (when or where clauses)
The parameter 'pv_some_Text' unfortunately not. (simple literals)
When I try to validate the above SQL, I get the following Error:
<font color="red">
java.io.IOException: prepare query failed[nQSError: 43113] Message returned from OBIS. [nQSError: 46033] Datatype: 25 is not supported.
</font>
After use a cast function:
>
else CAST(:pv_some_Text AS CHARACTER)
>
I get this ERROR:
<font color="red">
java.io.IOException: prepare query failed[nQSError: 43113] Message returned from OBIS. [nQSError: 19002] Incorrect use of parameters. The parameters used in CAST cannot be resolved without ambiguity.
</font>
We use OBIEE 11.1.1.6.4 on a Win64-System.
Thank's for any help.

Hi Alex,
let's leave away any unnecessary details.
This is the SQL, inserted in the window 'Edit Data Set' of BIP Data Model:
>
select
     '--1'     as Betr_Teil,
     '--2'      as Suva_Nr,
     sum("GDWH05"."DM15K_RIS_FAKTEN_PRO_BTT_JHR"."RIS_VOLLBESCH") as Vollbesch
from "GDWH05"
where
     "DM15D_BETRIEBSTEIL"."SUVA_NR_FORM" in ('122-4.4')
     fetch first 65001 rows ONLY
>
Everything is fine when I click OK, the script goes back to the metadata.
Let's try this script with bind values in ORACLE SQL Developer.
This SQL is the physical part, found in the OBIEE-Log (Log level 5), except the bind values. Therefore we find, in the where clause, the join. In the logical sql, we don't have to join, because it's handled in the Common Enterprise Information Model (CEIM)

with
sawith0 as
select
sum(t39617.ris_vollbesch) as c1
from
dm15d_betriebsteil t39455,
dm15k_ris_fakten_pro_btt_jhr t39617
where
t39455.id_betriebsteil = t39617.id_betriebsteil
and t39455.suva_nr_form = '122-4.4'
select
d1.c1 as c1,
d1.c2 as c2,
d1.c3 as c3
from
select
:pv_some_text as c1,
:pv_some_text as c2,
sum(d1.c1) as c3
from
sawith0 d1
d1
where
rownum <= 65001

This SQL works fine, even with bind values for 'pv_some_text'.
But, when using the following SQL in the BIP Data Model:
>
select
     :pv_Text as Betr_Teil,
     :pv_Text as Suva_Nr,
     sum("GDWH05"."DM15K_RIS_FAKTEN_PRO_BTT_JHR"."RIS_VOLLBESCH") as Vollbesch
from "GDWH05"
where
     "DM15D_BETRIEBSTEIL"."SUVA_NR_FORM" in ('122-4.4')
     fetch first 65001 rows ONLY

The following ERROR occurs:
<font color="red">java.io.IOException: prepare query failed[nQSError: 43113] Message returned from OBIS. [nQSError: 46008] Internal error: File server\Query\Optimizer\ServiceInterfaceMgr\Utility\Src\SQOIUTypeVisitor.cpp, line 643.</font>
In my opinion, either I use a wrong syntax, or BIP has a problem with parsing the script.
Thank you for your most welcome help.
