Error ORA-01422 apex: exact fetch returns more than the required number of line

Hi people,

Apex 4.1
I have a page that works like a charm.

Based on my application I need I have to perform the same operation for the different regions. As a quick and better method, I copied the page and branched, it inspires tab for this region.

The problem is that the original page works fine.
I haven't changed anything except the parent set to this copied page tab and works that I find with the above error.

It allows me to make the first entry on this page, but when I try to access the page again it gives me this error.

The error in detail is as below:

is_internal_error: false
ora_sqlcode:-1422
ora_sqlerrm: ORA-01422: exact fetch returns more than number of lines
Component.type: APEX_APPLICATION_PAGE_PROCESS

Copy paste is never advisable. It can be fast in some cases, there is an anti-pattern.

Be aware that the automatic extraction of the APEX line is based on a component of demand.

It is possible that your automatic rowfetch is based on the element of your previous page. If you for example to change the name of the table, but do not change the reference is the primary key value, then you can pass a value to your table that was not unique. This would result in ORA-01422.

Find the value of the session element and run your query.

-It's to return several rows, and the SELECT INTO statement expects that one line.

A SELECT INTO statement can be used if you want a query to return only one row. Otherwise use bulk collect and a variable of class to contain the result lines multiples.

Reasons to explain above, but I think it would be more appropriate select latest END_INTERVAL_TIME as follows

Select TO_CHAR ((max (END_INTERVAL_TIME)), "MM/DD/YYYY HH24")

in begin_date

If you don't have a way to restrict your query to return only 1 row according to the data, you can use the line number...
for example
```
select data, data2, .....
from (
select data, data2, ....., rownum rn
from table
)
where rn = 1
```

In the main table, there are two records of same, in this user name folders is different which defines the unique character of the file.

It is really basic and happens if you have something like this in your code - the SQL code is supposed to return exactly ONE value and it returns two or more:

The error is explicit:

ORA-01422: exact fetch returns more than number of lines

Cause: The exact extraction specified number is less than the rows returned.

Action: Rewrite the query or change the number of rows requested

This would imply the query in line 16 as County dissociated in the previous one will always return only one row.

Run
```
select T_AUTH.ID into x_auth_id
from T_AUTH_DTL T_AUTH_DTL,T_AUTH T_AUTH
where T_AUTH_DTL.AUTH_ID=T_AUTH.ID
and T_AUTH.USR_ID = :x_user_id

in the workshop of SQL by using the P41_USR_ID value in the variable link to find out how many rows it returns.

It is likely that the entire block can be replaced by a single INSERT statement. If you provide instructions CREATE TABLE, INSERT statements to create sample data and a clear definition of the requirements that we try to do.

What is the point of the inclusion of tables aliases that are exactly the same as the names of the tables?

This is my procedure:
In the clause select is causing the error. I understand the nature of the error, but the strange thing is that when I run the sql code, remove the "in."
part of my test settings, I just receive a single line. Always when I execute my procedure with the same settings I get the error. What could be wrong?

create or replace
PROCEDURE COUNTER_GETACTIVE

Open p_cursor for select * from counters where counternr = l_counterNr and meterId = l_meterId;

You actually run this query
```
select counternr, meterid from CounterBridgeTable where meterpointid = METERPOINTID and meterpointcounternr = METERPOINTCOUNTERNR and datetom is null;
```
param name is identical to the column, he's ignoring your param and pretty much do a self-join

Try this:
```
create or replace
PROCEDURE COUNTER_GETACTIVE
(
p_METERPOINTID IN MeterPointCounters.MeterPointId%Type,
p_METERPOINTCOUNTERNR IN METERPOINTCOUNTERS.METERPOINTCOUNTERNR%type,
p_cursor out REFCURSOR_PKG.counter_cursor
)
IS
l_counterNr CounterBridgeTable.CounterNr%type;
l_meterId CounterBridgeTable.MeterId%type;
BEGIN
select counternr, meterid into l_counterNr, l_meterId from CounterBridgeTable where meterpointid = p_METERPOINTID and meterpointcounternr = p_METERPOINTCOUNTERNR and datetom is null;

open p_cursor for select * from counters where counternr = l_counterNr and meterId = l_meterId;

END COUNTER_GETACTIVE;

Single - row subquery returns more than one line.

Hi Experts

I am faced with error

Please give some advice / solution.

I think this might do it for you

Select

TO_CHAR (T.MR_REG_DATE, 'DD') "DATE."

CASE

WHEN trunc ((MONTHS_BETWEEN (T.MR_REG_DATE, T.MR_DOB))) between 0 and 1 THEN ' 01' |'. - ('||' 0-1 month)"

WHEN trunc ((MONTHS_BETWEEN (T.MR_REG_DATE, T.MR_DOB))) BETWEEN 2 AND 12 THEN ' 02' |'. - ('||' 2-12 months)"

WHEN trunc ((MONTHS_BETWEEN (T.MR_REG_DATE, T.MR_DOB))) BETWEEN 13 AND 60 THEN ' 03' |'. - ('||' 1-5 years)"

WHEN trunc ((MONTHS_BETWEEN (T.MR_REG_DATE, T.MR_DOB))) BETWEEN 61 AND 120 THEN ' 04' |'. - ('||' 5-10 years)'

WHEN trunc ((MONTHS_BETWEEN (T.MR_REG_DATE, T.MR_DOB))) > 120 then ' 05' |'. ' - ('| ' > 10 years).
