Native CLOB and BLOB in RPG

CLOB and BLOB fields as dynamic size dependent on actual datasize. It would be appreciated that RPG could support these datatypes native in RPG and used exactly like varchar with out any explicit size


Use Case:

CLOB and BLOB is implemented as a structure containing a length (long integer) and a pointer to data (and for CLOB also an integer with the ccsid).

When data size changed, then the data is "realloc'ed" to the new actual size.

The access to a CLOB/BLOB is 100% identical as for varchars and also compatible with varchar. i.e. %subst, %len, '+' concat.

Code would look like ( note explicit size is not allowed for BLOB and CLOB):

dcl-s myClob CLOB *utf8;
dcl-s myVarchar VARCHAR(256) *utf8;

myVarchar = 'ABC';
myClob = myVarchar + myClob + 'XYZ';
myVarchar = %subst(myClob : 1 : 10);

    IBM does not intend to provide a solution to this request at this time, so it is being closed.

    It is not feasible for native RPG to access BLOB and CLOB data.

    The COMMON Europe Advisory Council (CEAC) has reviewed this requirement and recommends that IBM view this as a medium priority requirement that should be addressed.

    Background: The CEAC members have a broad range of experience in working with small and medium-sized IBM i customers. CEAC has a crucial 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.

    To find out how CEAC help to shape the future of IBM i, see CEAC @ ibm.biz/BdYSYj and the article "The Five Hottest IBM i RFEs Of The Quarter" at ibm.biz/BdYSZT

    The CAAC has reviewed this requirement and recommends that IBM view this as a medium priority requirement that should be addressed. As we move toward more unstructured data elements with AI, RPG needs to stay current and compatible.
