FRM-40501: ORACLE error: unable to reserve record for update or delete.
ORA-24374: define not done before fetch or execute and fetch
My master-detail form has single canvas. For both blocks, master and detail, two tables joined together in each. One table to be updated, second table has some info for reference (query only).
I am getting these errors when in detail block the item from LOV is selected for existing record. This does not happen for new record inserted in detail block.

I want to write a SELECT query on the data which are collected in a PLSQL table which is having 4 columns.
Looping through all the records in the PLSQL table will not get my requirement. Because I need to group the data based on two columns and need to fetch the count of groups.
Is there any way to query that PLSQL table?

I need to design a report out of the below data:
1. bprf_no will be my primary field
2. report parameters will be the bill_month & no_of_months
Based on above 2 parameters I need to scan through the data for BILL_MONTH <= '20-Jun-2012' and NO_OF_MONTHS <= 6 the other criteria being the AVG_IND in (1,2).
In brief the criteria will be to pick all BPRF_NO having AVG_ID in (1, 2) consecutively till a break (AVG_IND not in (1, 2) starting from the given BILL_MONTH and going below this period, that is BILL_MONTH <= '30-Jun-2012'.
For the below data, if my parameters are: BILL_MONTH <= '30-Jun-2012' and NO_OF_MONTHS <= 3, only the underscore added data should be picked (as they fulfill the criteria) and the report output will be like:
BPRF_NO BILL_MONTH NO_OF_TIMES
-------------------------------------------------
BP05 30-Jun-2012 6
BP06 30-Jun-2012 6
BP07 30-Jun-2012 6
BP08 30-Jun-2012 6
Here the NO_OF_TIMES is the count, that is no of times the BPRF_NO falls into the above mentioned criteria consecutively starting from the provided BILL_MONTH.
BPRF_NOBILL_MONTH VOID_STATUS AVG_IND
------- ----------- ------------ --------
BP0130-Jun-1200
BP0230-Jun-1200
BP0330-Jun-1201
BP0430-Jun-1201
_BP0530-Jun-1201_
_BP0630-Jun-1202_
[code]....
My below query is fetching me wrong data:
----- Query -----
select bprf_no, no_of_month--count(*)
from
(
select a.bprf_no, count(*) no_of_month
[code]....
Here BP03 & BP04 should not come into the listing itself.

we are using ERP System based on Oracle DB. I have an oracle client 10.2.0 installed on my machine (Win 7/64-Bit) and trying to create Excel(2010) VBA-Macro to get datas out of the Oracle DB using a SQL query:
On my old machine (Win XP/Excel 2007) following worked fine:
strConOracle = "Driver={Microsoft ODBC for Oracle}; " & _
"CONNECTSTRING=(DESCRIPTION=" & _
"(ADDRESS=(PROTOCOL=TCP)" & _
"(HOST=" & strHost & ")(PORT=1521))" & _
"(CONNECT_DATA=(SERVICE_NAME=" & strDatabase & "))); uid=" & strUser & " ;pwd=" & strPassword & ";"
Set oConOracle = CreateObject("ADODB.Connection")
Set oRsOracle = CreateObject("ADODB.Recordset")
oConOracle.Open strConOracle
Set oRsOracle = oConOracle.Execute(strSQL)
All the datas in the variables coming from cells or userforms - I am 100% sure all this is correct, as as said, it works on any Win XP Machine with Excel 2007
But trying same with Win 7/64-Bit/Excel 2010 gives me following error: MS ODBC Driver for Oracle: ora-01019: unable to allocate memory in the user side.

Is there a way to apply changes to a data field on oracle forms for specific users?
For example, I have an oracle form that applies the below masking code for a certain field called CUSTOMER_ID
IF :SYSTEM.BLOCK_STATUS = 'QUERY' THEN
SET_ITEM_PROPERTY('CUSTOMER_ID',CONCEAL_DATA,PROPERTY_TRUE);
ELSE
SET_ITEM_PROPERTY('CUSTOMER_ID',CONCEAL_DATA,PROPERTY_FALSE);
END IF;
But I only want this masking to be applicable to CERTAIN users. For example, the psuedo code would be like
IF :SYSTEM.BLOCK_STATUS = 'QUERY' and USERS_LIST = 'SUPERVISORS' THEN
SET_ITEM_PROPERTY('CUSTOMER_ID',CONCEAL_DATA,PROPERTY_TRUE);
Note that this users_list is a group of oracle database users, so I am a member of this group. Also note that this form is applied via the web via the application server.

I currently have a field in which the user inputs a number, but before this number is allowed to be saved to the database it has to be checked to see if the number is already stored in a different field within the database. For example, if the number is not in the database the user cannot put that number into the field.
I do want it to be user input so I don't want a LOV linked to the appropriate field in the database.
Is below anyway close to the way it should be done? For some reason seq_rec.seq seems to give me 3 and doesn't seem to compare it with each of the values in the database.
DECLARE
cursor seq_curs IS SELECT SEQ FROM ZZJOB;
seq_rec seq_curs%rowtype;
none_existing_seq EXCEPTION;
invalid_seq EXCEPTION;
return_alert NUMBER;
[code]....
Just say the field in my database has numbers: 1 2 3 4 and 5 in the field that i allow the user to input data they can only enter 1 2 3 4 or 5. Hence the check needs to be made with te database field to check if the input number is already in the database.
P.S. they are separate fields for different things, the numbers just need to be in one field before they can be added in the other.

2) while inserting using "values(timestamp'2011-03-24 11:03:00.05'" where this yyyy-mm-dd hh24:mi:ss.FF format comes from?
3)what is role of nls_timestamp_format of nls_database_parameters in this? how it allowed me to insert value "'12-mar-2011 14.03.00.055'" which has hh24 format?
4) Does the format of localtimestamp is decided by nls_database_parameters?
Note : I have not set nls_date_format in my session

After exporting some data to excel, I noticed that on one row all the columns shifted over some. So I queried this record in the database and noticed that the ADDRESS field has some unknown characters at the end of it. They are little squares. I think they are TABS.
2630 LINDEN BLVD, APT. #8G(2 squares are in here)
ADDRESS_1 "TRIM(:ADDRESS_1)",
Besides trimming the data, is there some other function I can use to clean up the address further?

I am struggling with a simple data load using sqlldr
Ref: I am running Oracle 11.2 on Linux 5.7.
===========================
Here is my table:
SQL> desc ntwkrep.CARD
Name Null? Type
[code]...
Looking at the actual data and counting the characters for the "REALIZES" column data, I see that it is roughly slightly over 1000 characters.
So, attempting various ideas to fix the problem, I tried changing nls_length_semantics to "char" and recreating the table, but this still didn't work and still got the same data load errors on the same rows.
Then, I changed nls_length_semantics back to byte and recreated the table again.This time, I altered the table manually as:
SQL> ALTER TABLE ntwkrep.CARD MODIFY (REALIZES VARCHAR2(4000 char));
Table altered.
SQL> desc ntwkrep.card
Name Null? Type
----------------------------------------------------------------- -------- --------------------------------------------
CIM_DESCRIPTION VARCHAR2(255)
CIM_NAME NOT NULL VARCHAR2(255)
COMPOSEDOF VARCHAR2(4000)
[code]...
Here is a copy of the first row of data which fails to load every time no matter how I change the "REALIZES" column in the table.
other(1)`CARD-mes-fhnb-bldg-137/1` `other(1)`CARD-mes-fhnb-bldg-137/1 [other(1)]`HwVersion:C0|SwVersion:12.2(40)SE|Serial#:FOC1302U2S6|` Chassis::CHASSIS-mes-fhnb-bldg-137, Switch::mes-fhnb-bldg-137 ` Port::PORT-mes-fhnb-bldg-137/1.23, Port::PORT-mes-fhnb-bldg-137/1.21, Port::PORT-mes-fhnb-bldg-137/1.5, Port::PORT-mes-fhnb-bldg-137/1.7, Port::PORT-mes-fhnb-bldg-137/1.14, Port::PORT-mes-fhnb-bldg-

I have a table where i need to update one field values based on another field of the same table , simply as it is.I have done this using one select all check box , on clicking that all check boxes of item_trans table will get selected , then i will un select some of check box and then using one button, i will update the value of the fields which are checked only.
I have put the sample code but when i am updating its taking long time and hanging.I am also attaching the form based on the test case provided.
--tables with insert statement
create table item_trans (trans_item varchar2(12),trans_qty number,trans_act_qty number)
insert into item_trans(TRANS_ITEM,TRANS_QTY,TRANS_ACT_QTY) VALUES ('TREE1',40,NULL);
insert into item_trans(TRANS_ITEM,TRANS_QTY,TRANS_ACT_QTY) VALUES ('TREE2',20,NULL);
insert into item_trans(TRANS_ITEM,TRANS_QTY,TRANS_ACT_QTY) VALUES ('TREE3',20,NULL);
--i want to set the value of trans_Act_qty as trans_qty
--i create one dummy or test block to keep the select all check box. for that table test script is
CREATE TABLE TEST
(
C VARCHAR2(2000 BYTE),
B NUMBER,
A NUMBER
);
insert into test (C,B,A) values ('A',1,1);
--code written in select all check box which is created on test.block.
BEGIN
GO_BLOCK('item_trans');
FIRST_RECORD;
LOOP
:M_END_YN := :M_END_ALL;
[code].......
--code written in M_END_YN ( actual check boxes where i will uncheck).
IF :M_END_YN = 'N' THEN
:M_END_ALL := 'N';
END IF;
--code written on button to update those values which are checked.

I have a tab named APPROPRIATIONS it has 10 fields. Among which is PROJECT NUMBER, AUTHORIZAION DATE (CALENDER TYPE POPUP), And FUNDS CHECK FLAG.
The Scenario is depending upon PROJECT NUMBER the Fields are Populated including FUNDS CHECK FLAG .
But the AUTHORIZAION DATE is a MANDATORY field has to be filled by User
The Requirement is to make AUTHORIZAION DATE as MANDATORY only when the FUNDS CHECK FLAG is *"BLANK "* or *“Y”*
If the FUNDS CHECK FLAG is *“N”* then the AUTHORIZAION DATE to be made OPTIONAL.
