ORA-01476: divisor is equal to zero Error in tabular form
Hello,
My tabular form will give me this error sometimes: Error in add row internal routine: ORA-01476: divisor is equal to zero. I don't understand what causes it. On the form I have a on load - before header process that will add 5 blank rows automatically, which was wizard generated. This error doesn't always happen, when I turn off this process and then turn it back on it works fine. Currently I have to set the condition to never, so I don't get the error. Is this a bug with Apex?
Also, when there is data available I have to click on the next arrow for the data to display.
Please advise.
Thanks,
Mary

Hello,
I have the same error message for ADD ROWS in tabular form. It is also happens when I try to open one empty record using On Load when page rendered. Have you found a fix for that ?
Thanks,
Marina

Error in add row internal routine: ORA-01476: divisor is equal to zero
Hi,
I am using Tabular Form Report in my application. So, when the user enters the page for the first time, no fields appear (if he has previously not entered any values in the DB). So to avoid this I added a Data Manipulation process-> Add rows to tabular Form ->On load after footer, so that when the user logins whether he entered previous values or not, he can see some empty fields, but this is not working as expected.
Any ideas how to resolve this issue.Hmm other people have had this errorm found this hope it helps,
Hi,
Have a look at: Re: Add Row in detail table when check box is checked on a master report table as this shows how you can use javascript to clone a row -

ROUND(SUM(VALOR_VDA) / SUM(DECODE(QTDE_VDA,0,1,QTDE_VDA)),2)
Oracle 10.2.0.1.0

The only issues here with the decode is see is if the total value of all the rows when summed is 0 - zero then you will have zero-divide error

Divisor is equal to zero error
Hi, I am getting divisor is equal to zero error while doing a calculation using sql. Is there a workaround this ?
ThanksWhat do you want to do, if the divisor is 0?
Is the SQL executed in SqlPlus or in a procedure/function?

group by tablespace_nameThe various NVL and DECODE solutions may get rid of the error, but will not get you the correct answer. By the way, you may want to look at the differences in behaviour between
(sum(fbyte)/decode(sum(byte),0,NULL))*100 free and
(sum(fbyte)/decode(sum(byte),0,1))*100 free before you use either.
Your real problem is that you have a temp tablespace using temporary files. This is the right thing to do, but, you need another union in your statement, to access dba_temp_files:
SELECT tablespace_name,SUM(obj_cnt) object_count,
SUM(ini_ext) init_ext, SUM(nex_ext) next_ext,
SUM(byte)/1048576 bytesize,

SUM(fbyte)/1048576 bytefree, SUM(frags), SUM(largest)/1048576 avail,
(SUM(fbyte)/SUM(byte))*100 free
FROM (SELECT tablespace_name, 0 obj_cnt, 0 ini_ext, 0 nex_ext, 0 byte,
SUM(bytes) fbyte, COUNT(*) frags, MAX(bytes) largest
FROM dba_free_space
GROUP BY tablespace_name
UNION ALL
SELECT tablespace_name,0, 0, 0, sum(bytes), 0, 0, 0
FROM dba_data_files
GROUP BY tablespace_name
UNION ALL
SELECT tablespace_name,0, 0, 0, sum(bytes), 0, 0, 0
FROM dba_temp_files
GROUP BY tablespace_name
UNION ALL
SELECT tablespace_name, 0, initial_extent/1024 ini_ext,
next_extent/1024 nex_ext, 0,0,0,0
FROM dba_tablespaces
UNION ALL
SELECT tablespace_name, COUNT(*) obj_cnt, 0, 0, 0, 0, 0, 0
FROM dba_segments
GROUP BY tablespace_name)
GROUP BY tablespace_nameYou should also use UNION ALL instead of UNION, because UNION implies a sort distinct, whil union all does not. The sort is unneccessary, and the distinct may cause you to lose rows.

Can you help please.Well the easiest way to troubleshoot this problem would be to find the row where FBASEVOLTAGE = 0. Something like this maybe:
SELECT BV.FBASEVOLTAGE

Looks like HTMLDB is removing the zeros?Billy,
I've confirmed this behavior but I cannot explain why it is happening. So for now, it'a a bug.

On a wizard generated tabular form on a table, I keep getting
Error in mru internal routine: ORA-20001: Error in MRU: row= 1, ORA-20001: ORA-20001: Current version of data in database has changed since user initiated update process.
when I click the Apply Changes button.
The data has definitely not changed.
How do I go about troubleshooting this? I did add some derived fields to the SQL query that the wizard generated, but they are not Editable, they are read-only fields.
I am at my wits end.
ThanksMarc:
I did the latter thing. I started with the wizard generated form, made sure it was working and added my changes one at a time, keeping my fingers crossed after each change! Its still fine.
<rant>
See the frustrating thing about the MRU error is that it gives absolutely no indication as to what the real problem is, it doesnt help to fix it. So basically one has to "backtrack" all the way to the beginning, the same way I did above i.e. start all over again. Its very time-consuming and counter-productive.
</rant>
Marc: Is there a way you can basically prevent changes to the wizard-generated form that would make it "not work" anymore?

Character string buffer too small error in tabular form
Hi Folks,
One of my tabular forms suddenly stopped working out of the blue after 3 months of working perfectly. So I've run into the debug and looks like something went wrong rendering my LOV as below:
0.16968 0.00328 ...Execute Statement: begin begin SELECT TIME_DISPLAY D, TIME_RETURN R bulk collect into wwv_flow_utilities.g_display,wwv_flow_utilities.g_value FROM TS_HOURS ORDER BY 2; end; end; 4

0.21211 0.00224 report error: ORA-06502: PL/SQL: numeric or value error: character string buffer too smallI've looked around and saw few others having same issues but nothing that's like mine. Could someone please help me find what the issue is? THanks.
I am using Apex 4.1.1Hi Andre, I have figured out the issue.
You were correct about the 32K limit. However it applies to the whole tabular form not to do with the particular LOV.
I tweaked my other LOV's (with 200 return value) to display fewer and this issue was resolved. I think there wasn't enough left for my 60 row LOV by the time APEX engine got to it which renders after the bigger LOV was rendered.
I think Advisor should have some kind of feature to check forms against 32k limit. Otherwise you wake up one morning and application broke after working 3 months perfectly. -
Hi
I created a tabular form. Also created a trigger that would insert a sequence number, user and system date each time a new record is inserted. I have associated an existing LOV to one of the fields.
I hit the 'Add Row' button. Select a value from the LOV for the account code. Hit the submit button and page indicates 1 row inserted.
I hit the 'Add Row' button again to insert another row and the following message appears:
Error in mru internal routine: ORA-20001: Error in MRU: row= 0, ORA-20001: ORA-20001: Current version of data in database has changed since user initiated update process. current checksum = "F246ADAF68494BEE51356ECC92B1047C", item checksum = "B9E444CAB12B67D92A5DBC8BB3E48517"., update "TEST"."VIEW_ACCOUNTS" set "CONTROL_SEQUENCE" = :b1, "ACCOUNT_CODE" = :b2
If I come completely out of the application and go back in to insert another record, I get the same error.Hi,
I think above probem is caused by the trigger created.
Check without the trigger for test-purposes and check if the error is gone. ( checksum error, I suppose )
Kind regards,

TJHi TJ,
You could write a JavaScript function to do that for you. Just call it onChange or onBlur. I have the following javascript functions that I use. These display the error next to the item though, so you may need to play around with it to display it where you want it to. (Pls note: I have a few validation functions like the notNull one below that all call the setError function.)
//This function checks to see if the object sent in is null and if so displays an error message
//back to the user. This is useful when doing client side validations on tabular forms in APEX.
//It takes in the ID of the object we want to do this check for and prints out an error
//just after the cell where the error occurred.
function notNull(object, errObj) {
var val = $x(object).value;
setError(object, (val == "" || val == null), "This field cannot be empty ", errObj);
//Function to display an error in a tabular form. The error will be displayed next to the field associated
//with the object parameter, using div tags. In addition to the object parameter, the function also takes in
//the err object to use as id in the div tag, a boolean variable to indicate if there is an error and the error string
//to display
function setError(object, isErr, errStr, errObj) {
//ensure you have the name for the error string to be displayed
if (!errObj) {
errObj = "err_".concat(object.id);
//if there was a prior error displayed, first delete that, so we do not have duplicate messages shown
$x_Remove(errObj);
if (isErr) {
if (!$x(errObj)) {
$x_Style(object, 'border', '1px solid red');
var errStr = ('<div name="err" id="').concat(errObj).concat('" style="color:red;">').concat(errStr).concat(' </div>');
object.parentNode.innerHTML += errStr;
$x("Back").focus();
$x(object.id).focus();
} else {
$x_Style(object, 'border', "1px solid #C8C8C8");
$x_Remove(errObj);
In the report item attributes page, I call the above function as onBlur="notNull(this);" in the element attribute field.

Error Creating Tabular Form in 4.2
I have a workspace with additional schemas granted. So, thew workspace has a parsing schema of SCHEMA_A but, schemas SCHEMA_B and SCHEMA_C have been granted.
I have confirmed that the appropriate permissions have been granted on a table in SCHEMA_B to SCHEMA_A. (U,I,S,D).
I can create an Interactive report on TABLE_A in SCHEMA_B without any issues.
However, if I go to add a Tabular Form, I pick the exact same table and I get the following error alert:
You do not have access to the schema you are importing
Import Failed
As further evidence that this is, indeed, a bug, I can create the form with some random table in the SCHEMA_A schema. Then, go edit the page and chnage it to select from the table in SCHEMA_B and everything works fine.
Help!
-JoeJoe, I was able to resolve my issue by following the advise here: How to change parsing schema for using application in test environment?
(In particular Roel's tip to login as Administrator in the Test environment and add the schema to the workspace schema('s))
