ERROR:
ORA-06550: line 38, column 8: PLS-00221: 'V_DATA_ARRAY' is not a procedure or is undefined ORA-06550: line 38, column 8: PL/SQL: Statement ignored ORA-06550: line 39, column 8: PLS-00221: 'V_DATA_ARRAY' is not a procedure or is undefined ORA-06550: line 39, column 8: PL/SQL: Statement ignored ORA-06550: line 40, column 8: PLS-00221: 'V_DATA_ARRAY' is not a procedure or is undefined ORA-06550: line 40, column 8: PL/SQL: Statement ignored ORA-06550: line 41, column 8: PLS-00221: 'V_DATA_ARRAY' is not a proc
Error
OK
CODE:
DECLARE
v_blob_data BLOB;
v_blob_len NUMBER;
v_position NUMBER;
v_raw_chunk RAW(10000);
v_char CHAR(1);
c_chunk_len number := 1;
v_line VARCHAR2 (32767) := NULL;
v_data_array wwv_flow_global.vc_arr2;
BEGIN
-- Read data from wwv_flow_files
select blob_content into v_blob_data
from wwv_flow_files where filename = 'DDNEW.csv';
v_blob_len := dbms_lob.getlength(v_blob_data);
v_position := 1;
-- Read and convert binary to char
WHILE ( v_position <= v_blob_len ) LOOP
v_raw_chunk := dbms_lob.substr(v_blob_data,c_chunk_len,v_position);
v_char := chr(hex_to_decimal(rawtohex(v_raw_chunk)));
v_line := v_line || v_char;
v_position := v_position + c_chunk_len;
-- When a whole line is retrieved
IF v_char = CHR(10) THEN
-- Convert comma to : to use wwv_flow_utilities
v_line := REPLACE (v_line, ',', ':');
-- Convert each column separated by : into array of data
v_data_array := wwv_flow_utilities.string_to_table (v_line);
-- Insert data into target table
EXECUTE IMMEDIATE 'insert into TABLE_X (v1, v2, v3, v4 ,v5, v6, v7,v8 ,v9, v10, v11)
values (:1,:2,:3,:4,:5,:6,:7,:8,:9,:10,:11)'
USING
v_data_array(1),
v_data_array(2),
v_data_array(3),
v_data_array(4);
v_data_array(5);
v_data_array(6);
v_data_array(7);
v_data_array(8);
v_data_array(9);
v_data_array(10);
v_data_array(11);
-- Clear out
v_line := NULL;
END IF;
END LOOP;
END;
what i understand from this is system does not identify v_data_array as array for some reasons, please help me.
initially system was giving error for hex_to_decimal, but i managed to get this function on discussion forum and now it seems to be ok. but v_data_array problem is still there.
thanks in advance

Hi,
Mistakes in your sample I did correct
Problem 1
select blob_content into v_blob_data
from wwv_flow_files where filename = 'DDNEW.csv'; to
select blob_content into v_blob_data
from wwv_flow_files where name = :P1_FILE;Problem 2
EXECUTE IMMEDIATE 'insert into TABLE_X (v1, v2, v3, v4 ,v5, v6, v7,v8 ,v9, v10, v11)
values (:1,:2,:3,:4,:5,:6,:7,:8,:9,:10,:11)'
USING
v_data_array(1),
v_data_array(2),
v_data_array(3),
v_data_array(4);
v_data_array(5);
v_data_array(6);
v_data_array(7);
v_data_array(8);
v_data_array(9);
v_data_array(10);
v_data_array(11);  to
EXECUTE IMMEDIATE 'insert into TABLE_X (v1, v2, v3, v4 ,v5, v6, v7,v8 ,v9, v10, v11)
values (:1,:2,:3,:4,:5,:6,:7,:8,:9,:10,:11)'
USING
v_data_array(1),
v_data_array(2),
v_data_array(3),
v_data_array(4),
v_data_array(5),
v_data_array(6),
v_data_array(7),
v_data_array(8),
v_data_array(9),
v_data_array(10),
v_data_array(11);  And I did create missing table
CREATE TABLE TABLE_X
    v1  VARCHAR2(255),
    v2  VARCHAR2(255),
    v3  VARCHAR2(255),
    v4  VARCHAR2(255),
    v5  VARCHAR2(255),
    v6  VARCHAR2(255),
    v7  VARCHAR2(255),
    v8  VARCHAR2(255),
    v9  VARCHAR2(255),
    v10 VARCHAR2(255),
    v11 VARCHAR2(255)
  );Regards,
Jari
