I have a question regarding oracle application express.
I want to upload the csv data to the database using apex application.
I used a code from otn but it does not work to the number datatype value..
It gives an error like number to charcter conversion error am not able to resolve it.
I also use TO_NUMBER functions to convert but it doesn't works..please help me out..
Following code I used to upload the data:
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;
v_rows number;
BEGIN
delete from chktable;
select blob_content into v_blob_data
from wwv_flow_files
where last_updated = (select max(last_updated) from wwv_flow_files where UPDATED_BY = :APP_USER) and id = (select max(id) from wwv_flow_files where updated_by = :APP_USER); v_blob_len := dbms_lob.getlength(v_blob_data); v_position := 1; 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; IF v_char = CHR(10) THEN v_line := REPLACE (v_line,',','~'); v_data_array := wwv_flow_utilities.string_to_table (v_line,'~'); EXECUTE IMMEDIATE 'insert into SRS_CC_MI_DATA(OUTAGE,TAR_#,CUSTOMER_NAME,RECEIVED,RESOLUTION_TIME,SEVERITY,PRIORITY)
values (:1,:2,:3,:4,:5,:6,:7)'
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_line := NULL;
END IF;
END LOOP;
END;
my table contains:
"OUTAGE" VARCHAR2(4000),
"TAR_#" VARCHAR2(4000),
"CUSTOMER_NAME" VARCHAR2(4000),
"RECEIVED" VARCHAR2(4000),
"RESOLUTION_TIME" VARCHAR2(4000),
"SEVERITY" VARCHAR2(1),
"PRIORITY" VARCHAR2(4000) NOT NULL ENABLE

Hello,
>> "PRIORITY" VARCHAR2(4000) NOT NULL ENABLE
What is the valid values of this column that you need to use varchar2(4000)? Are you sure this column include valid numbers?
