Native UTF-8 Support in Db2 DSNxLI Interfaces

We have some issues with customer's name, as we don't have this special characters in our codepage. So we try to use UTF-8 on the mainframe (as the data is coming raw in as UTF-8). PL/I and COBOL newly supports native UTF-8: COBOL: PIC U, PL/I: UCHAR.

Problem is, the Db2-Interfaces (for example DSNULI) does not support native UTF-8.

COBOL: IGYPS0212-S

PL/I: IBM3888I S 12.0 The reference <variable> has no corresponding DB2 type.


Please enable the Db2-Interfaces with the use of native UTF-8. COBOL, PL/I and Db2 supports this, but not the Db2-Interfaces.


Thank you, Patrick

    Hi Janet.

    I will not give up this topic until we understand us correctly. I think there are some misunderstandings.

    I have to do some more clarifications with the IBM PL/I responsible.

    Dear Patrick, Thank you for submitted this Aha! idea. The Db2 for z/OS team in this component area reviewed the idea and determined that, because they are not enhancing the Db2 precompiler, suggest that you instead use the Db2 coprocessor, if you want to include UCHAR type host variable in your application(s).

    We appreciate your input to the Db2 for z/OS development team. We hope that you will continue to submit enhancement suggestions for improvements as customer feedback is a key component to shaping the future direction of Db2 for z/OS.

    Sincerely,

    The Db2 for z/OS Team

    Hi Patrick, Can you please let us know if you were using the precompiler or coprocessor? Thank you.

    Just found the documentation about the SQLTYPE and Cobol:

    https://www.ibm.com/docs/en/db2-for-zos/12?topic=statements-equivalent-sql-cobol-data-types

    There may be new types for UTF-8 Character Data.

    I think, the problem ist, that there is no responding SQLAVTYPE (example: SQLPLIST7.SQLAVARS.SQLAVTYPE(1) = 452;) for UTF-8 in the SQL Parameterlist of an "EXEC SQL".

    Hi Janet

    We need Unicode Support in the DSNULI Db2 Interface for (PL/I Language): UCHAR, VARYING UCHAR and CLOB Datatypes.

    It is mentioned on https://www.ibm.com/docs/de/db2-for-zos/12?topic=scya-specifying-ccsids-pli-applications-when-using-db2-coprocessor

    as UCHAR (CCSID 1208).


    Nothing to do with RACF, just special (Unicode) Characters we need to get and put into Db2 (only DATA), read (SELECT) and written (INSERT) without any conversion.

    Hello Patrick, The Db2 for z/OS development team has reviewed this enhancement request. Could you kindly review their below questions and reply?

    Which variables or character strings do you need unicode support for?

    1. customer's name - does that mean the RACF authid on the connection call

    2. variables used in the connection function calls, for example CONNECT, OPEN for CAF or IDENTIIFY, SIGNON for RRSAF

    3. SQL data in Db2 tables or SQL statements


    Thank you.
