Allow SQL Precompiler to handle longer names of fields

It must be possible to use long names of fields/attributes defined in qualified data structures when building applications using modern free format RPG with embedded SQL.


Use Case:

When using names for fields/attributes defined in qualified data structures there is a limit of how long names the SQL Pre-compiler can handle when these fields are used in the embedded SQL statements. This leads to strange compile errors that are very hard to understand.


Idea priority High

    The CAAC has reviewed this requirement and recommends that IBM view this as a medium priority requirement that should be addressed. As the use of qualified data structures is expanded, the size of the variable names needs to increase.

    Background: The COMMON Americas Advisory Council (CAAC) members have a broad range of experience in working with small and medium-sized IBM i customers. CAAC has a key role in working with IBM i development to help assess the value and impact of individual RFEs on the broader IBM i community, and has therefore reviewed your RFE.

    IBM will use this request as input to planning but no commitment is made or implied. This request will be updated in the future if IBM implements it.

    The CEAC has reviewed this requirement and recommends that IBM view this as a HIGH priority requirement that is important to address.

    To be able to build modern RPG applications we long descriptive attribute names to increase the number of characters would help to improve the image of RPG.

    It is the limit of 64-characters that is the problem. This when the host variables used in the SQL statement is based on a qualified DS with a long a name with subfields with long names. The limit of 64 characters should be extended to for example 128 characters.

    Here is an example:

    EXEC SQL
    SELECT MachineLine_ID, DimDiesIndicator, UsedFrom, UsedUntil, SeriesID, SeriesName,
    Update_TS, Update_User
    INTO :Create_MachineLineDimensionAndDiesSeries_Data
    FROM FINAL TABLE(
    INSERT INTO NLPMDDV2
    VALUES(
    :v1_Create_MachineLineDimensionAndDiesSeries_Data.MachineLine_ID,
    :v1_Create_MachineLineDimensionAndDiesSeries_Data.DimensionDiesIndicator, <= Too long...
    :v1_Create_MachineLineDimensionAndDiesSeries_Data.UsedFrom,
    :v1_Create_MachineLineDimensionAndDiesSeries_Data.UsedUntil,
    :v1_Create_MachineLineDimensionAndDiesSeries_Data.SeriesID,
    :v1_Create_MachineLineDimensionAndDiesSeries_Data.SeriesName,
    DEFAULT,
    DEFAULT ));

    Please provide an example of what you are trying to do.

    - Have you coded the ALIAS keyword for your File or DS definitions? You do need to code ALIAS to use the long names.
    - Or do you want to use names that are longer than the 64-character limit for the SQL precompiler?

    Specify the Alias keyword on the DS... Dcl-DS MyDS ExtName("MYFILE") Qualified Alias;

    Or are you referring to another issue, please provide an example.
