Bulk insert using FORALL in Oracle

Question

I am currently using the following code to do a bulk insert of 50 million rows:

declare cnt number;
BEGIN 
    select max(run_ver_issue_id) into cnt from "ABHINAV"."MV_RUN_VER_ISSUE";
    FOR x IN 1 .. 50000000 LOOP
         INSERT INTO "ABHINAV"."MV_RUN_VER_ISSUE" NOLOGGING ("RUN_VER_ISSUE_ID","CUST_ISSUE_ID","TITLE","ORIGINAL_ISSUE_ID","SOURCE_FILE_LINE","DISPLAY_TEXT","RUN_VER_ID","SANDBOX_SRC_FILE_ID","ACCOUNT_ID","ISSUE_STATE","CURRENT_SEVERITY","INSERT_TS","MODIFIED_TS","CWE_ID","TEMPLATE_FILE_ID","TEMPLATE_FILE_LINE","CURRENT_EXPLOIT_LEVEL","CNT","SOURCE_FUNCTION_PROTOTYPE","SOURCE_RELATIVE_LOCATION","SOURCE_SCOPE","PROCEDURE_NAME","PROCEDURE_HASH","PROTOTYPE_HASH","STATEMENT_HASH","STATEMENT_HASH_COUNT","STATEMENT_HASH_ORDINAL","SUBMODULE_PATH") VALUES (x+cnt,2,..);
    END LOOP;
END;

It takes almost 6 hours it to finish. The table does have an index on RUN_VER_ISSUE_ID, but still doesn't help. I tried using FORALL, getting an error PLS-00430: FORALL iteration variable X is not allowed in this context for the below code:

declare cnt number;
BEGIN 
    select max(run_ver_issue_id) into cnt from "ABHINAV"."MV_RUN_VER_ISSUE";
    FORALL x IN 1 .. 5
    INSERT INTO "ABHINAV"."MV_RUN_VER_ISSUE" NOLOGGING ("RUN_VER_ISSUE_ID","CUST_ISSUE_ID","TITLE","ORIGINAL_ISSUE_ID","SOURCE_FILE_LINE","DISPLAY_TEXT","RUN_VER_ID","SANDBOX_SRC_FILE_ID","ACCOUNT_ID","ISSUE_STATE","CURRENT_SEVERITY","INSERT_TS","MODIFIED_TS","CWE_ID","TEMPLATE_FILE_ID","TEMPLATE_FILE_LINE","CURRENT_EXPLOIT_LEVEL","CNT","SOURCE_FUNCTION_PROTOTYPE","SOURCE_RELATIVE_LOCATION","SOURCE_SCOPE","PROCEDURE_NAME","PROCEDURE_HASH","PROTOTYPE_HASH","STATEMENT_HASH","STATEMENT_HASH_COUNT","STATEMENT_HASH_ORDINAL","SUBMODULE_PATH") VALUES (x+cnt,2,.....);
END;

I would request you to please provide your suggestions and comments as to how I can speed this up.

Answer 1

you may use this:

declare 
    p_array_size number := 100000; 
    type array is table of number;
    l_data ARRAY;
    cursor c is select rownum seq_no from dual connect by rownum <= p_array_size; 
    cnt number;
begin 
    open c;
    loop
        select max(RUN_VER_ISSUE_ID) into cnt from "ABHINAV"."MV_RUN_VER_ISSUE"; 
        fetch c bulk collect into l_data limit p_array_size;
        forall x IN 1 .. l_data.count
        insert into "ABHINAV"."MV_RUN_VER_ISSUE"("RUN_VER_ISSUE_ID","CUST_ISSUE_ID","TITLE","ORIGINAL_ISSUE_ID","SOURCE_FILE_LINE","DISPLAY_TEXT","RUN_VER_ID","SANDBOX_SRC_FILE_ID","ACCOUNT_ID","ISSUE_STATE","CURRENT_SEVERITY","INSERT_TS","MODIFIED_TS","CWE_ID","TEMPLATE_FILE_ID","TEMPLATE_FILE_LINE","CURRENT_EXPLOIT_LEVEL","CNT","SOURCE_FUNCTION_PROTOTYPE","SOURCE_RELATIVE_LOCATION","SOURCE_SCOPE","PROCEDURE_NAME","PROCEDURE_HASH","PROTOTYPE_HASH","STATEMENT_HASH","STATEMENT_HASH_COUNT","STATEMENT_HASH_ORDINAL","SUBMODULE_PATH")
