Insert records into non base table

Hi
I would like to insert records into a table when a button is clicked. The table is a non base table. I am trying to save records displayed in a form into a history table which is not part of the form. I am using the following code stored in a program unit then called when the button is pressed. It doesn't generate any error but the records are not inserted. Can anyone please help.
hist_id := 1;
cust_name := :CUSTOMER.cust_name;
loan_date := :LOAN.loan_date;
return_date := LOAN.return_date;
FORMS_DDL('INSERT INTO LOAN_HISTORY VALUES'||hist_id||','||cust_name||','||loan_date||','||return_date);

Why do you need forms_ddl built in for a DML statement to be used in form?
U can directly use insert.
hist_id := 1;
cust_name := :CUSTOMER.cust_name;
loan_date := :LOAN.loan_date;
return_date := LOAN.return_date;
INSERT INTO LOAN_HISTORY VALUES (hist_id,cust_name,loan_date,return_date);
It should work perfectly.

Cannot INSERT records into Partitioned Spatial Table and Index

I am trying to tune our Spatial Storage by creating partitioning our spatial_entity table and index. I used the World Geographic Reference System (GEOREF) creating a partition for each 15 x 15 degree grid square assigning a partition key of decimal longitude, decimal_latitude. The build went OK, however when trying to insert a data record I receive an ORA-14400: Inserted partition key does not map to any partition.
I validated the CREATE(s), and all appears correct, but obviously something is not correct, which is prompting for expert help in this forum.

Thank you for your quick reply. I did not post the entire CREATE script as it is quite long. The portion of the script that is applicable to the INSERT is:
,PARTITION p_lt_45e_90s
          VALUES LESS THAN (23, -90)
     ,PARTITION p_lt_45e_75s
          VALUES LESS THAN (23, -75)
     ,PARTITION p_lt_45e_60s
          VALUES LESS THAN (23, -60)
     ,PARTITION p_lt_45e_45s
          VALUES LESS THAN (23, -45)
     ,PARTITION p_lt_45e_30s
          VALUES LESS THAN (23, -30)
     ,PARTITION p_lt_45e_15s
          VALUES LESS THAN (23, -15)
     ,PARTITION p_lt_45e_0
          VALUES LESS THAN (23, 0)
     ,PARTITION p_lt_45e_15n
          VALUES LESS THAN (23, 15)
     ,PARTITION p_lt_45e_30n
          VALUES LESS THAN (23, 30)
     ,PARTITION p_lt_45e_45n
          VALUES LESS THAN (23, 45)
     ,PARTITION p_lt_45e_60n
          VALUES LESS THAN (23, 60)
     ,PARTITION p_lt_45e_75n
          VALUES LESS THAN (23, 75)
     ,PARTITION p_lt_45e_90n
          VALUES LESS THAN (23, maxvalue)
Or, I do not fully understand. Are you indicating that I must explcitly state the longitude in each clause,
e.g ,PARTITION p_lt_45e_45n
          VALUES LESS THAN (45, 45)
,PARTITION p_lt_45w_45n
          VALUES LESS THAN (-45, 45)
If so, that answers the question of why it cannot find a partition, however an Oracle White Paper "Oracle Spatial Partitioning Best Practices" Sept 2004, discusses multi column partitioning such as represented by this problem, and gives an INSERT statement example of :
CREATE TABLE multi_partn_table (in_date DATE,
geom SDO_GEOMETRY, x_value NUMBER, y_value NUMBER)
PARTITION BY RANGE (X_VALUE,Y_VALUE)
PARTITION P_LT_90W_45S VALUES LESS THAN (1,-45),
PARTITION P_LT_90W_0 VALUES LESS THAN (1,0),
PARTITION P_LT_90W_45N VALUES LESS THAN (1,45),
PARTITION P_LT_90W_90N VALUES LESS THAN (1,MAXVALUE
and as I am writing this I am seeing that I failed to include the longitude and latitude in the SDO_GEOMETRY clause, so it does appear tht I need to explicitly state the longitude valuues.
What is your judgement sir?

Problem - Inserting Records into Hashed Tables

Help for an ABAP Newbie...
How do I insert records into a hashed table?

Inserting records into Table with check table logic in place

I want to insert records into a table, and have the check table to not allow invalid entries. Is there a function out there that will allow this? I am currently using the insert statement and it is working except that it is not giving an error when the value does not exist in the check table for the particular fields.
INSERT INTO ZSD_XREF VALUES WA_XREF.
That is the basic statement I'm using ZSD_XREF has several fields one being the material number field tied to the check table which happens to be MAKT file. The insert statement is not validating the material numbers using the check table, or at least it is not giving an error. Any ideas?

Paul,
Unfortunately, open SQL statements such as INSERT, UPDATE do not go through the check table logic as they directly hit the database layer. Check table checks are performed only if you go through application layer that is when you enter the same data through a screen.
You have to do the checks yourself.
Happy checking!!!

Inserting records into a table with all caps

Hello
I have a procedure that inserts records into a table. How do I ensure that the text values inserted are recorded all capital letters into the table?
Thanks.

You can use UPPER(..) function in your insert statement, so that values are converted to UPPER, before insert.
If you want to check at table level, you can achieve that by writting a before insert trigger and in that trigger check
IF UPPER(:new.<col>) != :new.<col> THEN
RAISE_APPLICATION_ERROR(-20101,'Error: Not all values are in upper case')
END IF;

Efficient Way of Inserting records into multiple tables

Hello everyone,
Im creating an employee application using struts framework. One of the functions of the application is to create new employees. This will involve using one web form. Upon submitting this form, a record will be inserted into two separate tables. Im using a JavaBean (Not given here) between the JSP page and the Java file (Which is partly given below). Now this Java file does work (i.e. it does insert a record into two seperate tables).
My question is, is there a more efficient way of doing the insert into multiple tables (in terms of performance) rather than the way I've done it as shown below? Please note, I am using database pooling and MySQL db. I thought about Batch processing but was having problems writing the code for it below.
Any help would be appreciated.

Using Crystal 2008 to insert records into a table

Hi,
We have a unique need to use Crystal to insert records into a table. We have managed to test a report that can write into a temporary table. This is done by using sql command object and uses the following code :
INSERT INTO TEMP_TABLE (ORDERID)
VALUES ({?orderid}) (-- where orderid a parameter).
This test report asks for an order id and then inserts the record perfectly fine.
Now moving on to the real report - This report basically prints orders in batches and we want to insert order id into a temporary table to ensure we don't print orders that were already printed. To do this we created a sub report "insert orders" that has the above insert command. The main report passes the orderid to subreport and the idea is that the subreport would insert each time an order is passed. So if main report printed 50 orders ids, the then it would do 50 inserts individually into the temp table.
This however is NOT working. The report runs fine but there is no insert. Our hunch is that Crystal is not committing after every order id is passed from the main report. Not sure if we can set the AUTO COMMIT ON as a default somewhere?
Wondering if any one has attempted this or has any insights?
Regards,
Mohit.
Environment is - Crystal 2008 and Oracle 11GR2, we are using Oracle drivers (and not odbc)

Hmmm... I don't use Oracle but the syntax looks good...
You've already tested it and I assume that you are using the same driver in the production report as you used in the test, so that shouldn't be an issue...
how are you pulling the data? Is the final SELECT statement that pulls the report data in the same command as the INSERT script, or is the INSERT script in it's own command?
The reason I ask... If you are trying to pass a multi-valued parameter to a command, it won't work. If you have the insert command as it's own command while the data is being pulled with linked tables or a separate command, it is possible that the report itself will execute as expected w/o passing a value to the insert script.
If it's all in 1 command (as it should be), a bad parameter would fail in the final SELECT causing an error.
Also... are rows null or empty string values being added to table when the report executes? This would be an indication that the command is being executed but isn't getting the parameter value.

Use SQL to INSERT a record into an Access table and populate using variables

I am having difficulties with the following code:
'Get my username
UserNameWindows = GetUserName
'Assemble my name and request corrections
MsgBoxTitle = "What name do you want to use?"
NewDefault = Replace(UserNameWindows, ".", " ")
NewDefault = StrConv(NewDefault, vbProperCase)
MyValue = InputBox(Message, MsgBoxTitle, NewDefault)
RealName = MyValue
'Assemble your email address
MsgBoxTitle = "What is your email address?"
NewDefault = UserNameWindows & "@calibreglobal.com.au"
MyValue = InputBox(Message, MsgBoxTitle, NewDefault)
EmailAddress = MyValue
MsgBox "Your UserNameWindows value is " & UserNameWindows & "."
'Insert UserNameWindows into the tblAuthorisedPeople table
strSQL = "INSERT INTO tblAuthorisedPeople (Person, RealName, EmailAddress) VALUES (" & UserNameWindows & ",""" & RealName & """, """ & EmailAddress & """)"
DoCmd.RunSQL (strSQL)
It asks me to enter the value for the Person field into a dialogue box instead of using the value of UserNameWindows.
After entry, it accepts the other values and enters the record correctly.
I have also tried this SQL string without success
strSQL = "INSERT INTO tblAuthorisedPeople (Person, RealName, EmailAddress) VALUES (" & Forms!frmCreateNew!UserNameWindows & ",""" & RealName & """, """ & EmailAddress & """)"
Any comments?
Barry Cuthbertson

Found the error. I had used the rules for the syntax from a web forum reply which appears to have been incorrect!
strSQL = "INSERT INTO tblAuthorisedPeople (Person, RealName, EmailAddress) VALUES (""" & UserNameWindows & """,""" & RealName & """, """ & EmailAddress &
This seems to be working well as the moment
All finished.

Can BO Enterprize SDK inserts records into user table

From Infostore can we create a jsp script using Java SDK to inserts records into user table??
Thanks
Amar

Hi Amar,
I want to retrieve data/records from Infostore and insert into a user table using JSP script. Is it possible to do this?
Infostore is a database used by BO Server. so any changes made in infostore through BO enterprise session is valid.
Say u want to retrive on of report present in folder <my folder>.
The you have to query for that. for eg.
boinfostore.query("select * from ci_infoobjects where si_kind ='report' and si_foldername='my folder'");
Create/add/insert any new information in infostore is done by functionalities provide by SDK.
like adding the user or scheduling a report will add new object to infostore.
If you directly access cms database and make any changes then , I am afraid you will end up with nightmare.
So it is always recommneded to access infostore/ cms database only from bo session.
For more information refer below link
[http://devlibrary.businessobjects.com/BusinessObjectsXIR2SP2/en/devsuite.htm]
then under Contents
BusinessObjects Enterprise SDK >> COM developer guide and API reference >> Query Language Reference
do revert if any queries
Thanks,
Praveen.

Tabular form with non base table field

I want to develop a tabular form with
1. A non-base table edit field to accept a value
2. Insert/update another table based on the input value
3. Also, computed field on each row based on other fields on the records (like post-query trigger in oracle forms at block level - for each row)
Thanks,
Rachna

Thanks for your reply.
Varad, I like the link you sent me. It has a lot of good information.
I created a process (under page processing) called "Update/Insert Process" that dosn't seem to be working.
Question, I created a manual tabular form with SQL Query and created a process (under page processing) called "Update/Insert Process", then I check for each record in the tabular form. If the old value <> new value then I update/insert in the new table.
Any step by step will be highly apprciated - to create process/validation etc.
Thanks,
Rachna

Can Shuttles be based non-base table ViewObjects with transient attributes

Hello,
Users have to select records from a data collection and a Shuttle looks most appropriate/nice for this purpose. We can introduce technical intersection tables in order to generate the Shuttles with JHeadstart 10g R3 if necessary, but there is no “functional” need to update any data in the database and therefore it would be practical if the ‘right’ side from a Shuttle can be based non-base table ViewObjects with transient attributes only. So, our interested is to know which records have been selected, i.e. moved to the right side from the Shuttle.
Hope that my question is clear enough.
Greetings,
Michael

Michael,
This cannot be generated out-of-the-box.
It is easiest to add the shuttle post-generation to your page, and then create a custom template to generate your custom shuttle into the page. I suggest you take a look at an example of a generated shuttle in a page, and the JHeadstart IntersectionShuttleBean class. You will see that the value property of <af:selectManyShuttle> points to the selectedKeys method in the JHeadstart Shuttle bean. In your case, you can create your own managed bean and bind the value property to your own method which will provide you access to the selected rows. The value property of the selectItem within the af:selectManyShuttle determines the property that is used to identify the selected row (which is the row key in case of Jhs-generated shuttles).

@Inserting Records in an Internal Table

Hi,
How can I Insert records in an internal table..such that i can insert the records somewhere in the middle based on the entry in a field?

INSERT wa INTO TABLE itab INDEX idx .
Effect
This variant can only be used for standard tables and sorted tables. Each line line_spec to be inserted into the line before the table index idx and the table index of the following lines is increased by one. A data object of the type i is expected for idx.
If idx contains a value equal to the number of the existing table lines plus one, the new line is appended as the last line in the internal table. If idx contains a greater value, no line is inserted and sy-subrc is set to 4.
An exception that cannot be handled is raised when:
idx contains a value less than or equal to 0
A line to be inserted would cause a duplicate entry in tables with a unique table key
A line to be inserted would disrupt the sort order of sorted tables
Within a LOOP loop, you can omit the addition INDEX. Each line to be inserted is inserted before the current table line of the LOOP loop. However, if the current line is deleted in the same loop pass, the response is undefined.

Thank u very much.
First I tried with out the servlet. I took a simple class. But it was displaying the null pointer exception.
then you still have the problem. do you understand the root cause?
After then I made a servlet. how was that going to help your null pointer exception?
Now it is displaying error hibernate.cfg.xml not found.that's part of the problem. where is the servlet reading that file and initializing the session factory? how is it finding that file?
i don't know where you have that .cfg.xml file, or where the recommended place is where hibernate expects to see it, but i'd bet it needs to be in the CLASSPATH, which means WEB-INF/classes.
figure out why you get that NPE first, though. the servlet is only making things worse.
