Make an update statement from a proc
That is, how is possible to call an update statement from
within a procedure?
I have tried
execute update TT_Livraison set ...
without success.
Any idea?
In a procedure, you just include the SQL statement
CREATE OR REPLACE PROCEDURE foo ...
AS
BEGIN
UPDATE <<some table>>
SET ...
END;Justin

Generate update statement from select results
I'm trying to generate an update statement based off select statement results. A very basic example,
SELECT ListID FROM DListing WHERE Status = 2
Results return 3 rows.
1234
2345
3456
How can I take those results and turn them into WHERE criteria for UPDATE statement?
Generated UPDATE statement should look like this.
UPDATE DListing SET Status = 1 WHERE ListID IN (1234,2345,3456)
I have started by creating a temp table to hold my SELECT results, but I don't know how to get those results into format for IN condition. Right now I get 3 UPDATE statements with 1 ListID in each IN condition.
CREATE TABLE #TempStatusUpdate(ListID INT)
INSERT INTO #TempStatusUpdate
SELECT ListID FROM DListing WHERE Status = 2
SELECT 'UPDATE DListing SET Status = 1 WHERE ListID IN (' + CONVERT(VARCHAR(30),ListID) + ') AND Status = 2'
DROP TABLE #TempStatusUpdateSo what wrong with
UPDTATE DListing
SET Status = 1
WHERE ListID IN (SELECT ListID FROM #TempStatusUpdate)

Delete/update statements insite stored proce
I know this is probably fairly simple for some of you, but I am brand new to Oracle-SQL. In Sybase you can have the following stored procedure and works:
create procedure foo as
begin
create table ...
create index...
delete x
where ....
update x
where ...
end
In oracle everytime I need to execute a DML comand in a stored proc do I have to use execute immediate ('delete x...')?
thanks> the above is not an application code, it is a simple
and dirty maybe way to transfer some data from
microsoft access to oracle. so, i need a quick and
disrty way to transfer this data.
I would have been using a SQL*Plus script myself to do this and not a stored procedure.
> is it there a limit of how many tables i can cerate
inside my stored proc using:
execute immediate('CREATE TABLE xxx AS select * from
yyy.... ?
No. Of course not.
Just keep in mind that each DDL is an implicit commit.
> i have a stored proc that creates couple tables with
the method shown above but the compiler compains for
the second create table zzz as select * from .... any
idea why?
DDL statement and error number are? -
SQL UPDATE statement in MS Excel
Hi All,
I have a request to perform a column update in ap_invoices_all table. There are around 1000 rows to be updated. The input is in the form of MS Excel.
Can somebody suggest how to make an update statement using MS Excel.
My query using excel should look like below:
UPDATE AP_INVOICES_ALL
SET description = '',
last_update_date = ,
last_updated_by =
WHERE org_id =
AND vendor_site_id =
AND invoice_num = ''
Regards,
Radhika.>
Can somebody suggest how to make an update statement using MS Excel.
>
as a way:
-- create heterogeneous service for ms excel
-- create dblink for this service
-- do update like
UPDATE AP_INVOICES_ALL
SET description = (
with t as
select value_for_description,
org_id,
vendor_site_id,
invoice_num

select t.value_for_description
from t t
where s.org_id = t.org_id
and s.vendor_site_id = t.vendor_site_id

Updating data without using update statement
Hi,
A quick question...
Can any table data could be updated without using update statement from backend.
Just wanted to make sure.
Thanks in advance.Hi,
What is your definition of Update?
Since your question is vague and you dont explain what exactly you mean.
here are my thoughts
1) A record can be deleted and isnerted with new values.Where the nes values have only few columns changed from previous ones.
2) I use pl/sql developer.If i need to update i can write select.. for update.Change the values (as in notepad)Commit.
This is infact a update but with nice UI
3) even your application can update data in your tables, if you code it and give correct privileges to the userRegards,

Help with this update statement..
Hi everyone,
I am trying to update a column in a table .I need to update that column
with a function that takes patient_nbr and type_x column values as a parameter.
That table has almost "300,000" records. It is taking long time to complete
almost 60 min to 90 min.
Is it usual to take that much time to update that many records?
I dont know why it is taking this much time.Please help with this update statement.
select get_partner_id(SUBSTR(patient_nbr,1,9),type_x) partner_id from test_load;
(it is just taking 20 - 30 sec)
I am sure that it is not the problem with my function.
I tried the following update and merge statements .Please correct me if i am wrong
in the syntax and give me some suggestions how can i make the update statement fast.
update test_load set partner_id = get_partner_id(SUBSTR(patient_nbr,1,9),type_x);
merge into test_load a
using (select patient_nbr,type_x from test_load) b
on (a.patient_nbr = b.patient_nbr)
when matched
then
update
set a.partner_id = get_partner_id(SUBSTR(b.patient_nbr,1,9),b.type_x);
there is a index on patient_nbr column
and the statistics are gathered on this table.Hi Justin,
As requested here are the explain plans for my update statements.Please correct if i am doing anything wrong.
update test_load set partner_id = get_partner_id(SUBSTR(patient_nbr,1,9),type_x);

Update statement getting ORA-00904 invalid identifier
I am getting this ORA error when I try to conduct an update statement from a column value in one table to a like-named column in another table.
For instance, in my select, shown below, this query runs like a champ, returning all of my records
SELECT
b.ID,
b.ZIP, a.ZIP,
a.NAME,
a.LOCATION
FROM TBL_ARCHIVE a
INNER JOIN TBL_UAT b ON
a.ID = b.ID
WHERE
b.ID > 470000 And b.ID <470100;However, if I try to run an update statement with any of the following, I get this error. It seems so strange to me that I'd get an error using the same columns in the update statement, but would return the desired results effectively from the select statement!
one version of UPDATE
UPDATE TBL_ARCHIVE a
SET a.ZIP = TBL_UAT.ZIP
WHERE TBL_UAT.ID = a.ID;and another
UPDATE TBL_ARCHIVE
SET a.ZIP =
(SELECT b.ZIP
FROM TBL_UAT b
WHERE b.ID <472500 And b.ID >471000)
FROM TBL_ARCHIVE a
WHERE a.ID = b.ID)
WHERE ID IN
(SELECT ID
FROM TBL_UAT b
WHERE b.ID <472500 And b.ID >471000
);^ - this one produces a SQL not properly ended. Error ORA-00933: SQL command not properly ended.
I'm really unsure though, how what I thought was a fairly basic update statement wouldn't work. I'm using Oracle 11g but through either Toad or SQL Plus. I've gotten these same errors in both.
Though MS Access runs slow as snails, I can manage to run the update statement successfully with it, a thousand records or so at a time. Problem is, I've got about 300K records needing updating.
I've looked around for similar problems but haven't found one where someone wasn't either using a reserved word for a column, which I'm not, I don't believe, or a problem that really dealt with this error in the context of an update statement.
But I'd welcome any enlightenment on this.rp0428 wrote:
UPDATE TBL_ARCHIVE a
SET a.ZIP = TBL_UAT.ZIP
WHERE TBL_UAT.ID = a.ID;That isn't a valid query and neither is the other one.
Please post the actual query you are using and the actual complete error message you are getting (everything about the error that is displayed).^^
That is NOT a valid query?
How else would you have an UPDATE statement created to set the value of a column in table A to the value of a (in this case, same named) column in table B?
And keep them in order to update the records appropriately?
I'll append the create statements momentarily.
Thanks!
CREATE TABLE TBL_UAT
( ID NUMBER(6),
ZIP VARCHAR2(10 BYTE) ) and
CREATE TABLE TBL_ARCHIVE
( ID NUMBER(6) NOT NULL, NAME VARCHAR2(50 BYTE),

Is there any special way of calling UPDATE and INSERT routines.
As my select statements are doing fine, but i m getting error with UPDATE and INSERT. I am getting the following error
Can Anyone guide me ?

It looks like you are using either :
1. A READONLY CACHE GROUP with PassThrough > 0.
or
2. An SWT CACHE GROUP
Is that correct? This looks like a mismatch between the TT Oracle library and the version of the Oracle client that you have installed (or maybe a bad setting of LD_LIBRARY_PATH).
What is the exact version of TimesTen you are using (output of ttVersion command)?
What is the exact version of Oracle?

Hi,
I need some specific features for my school project and BDB is almost providing me with this functionality. In my project, I want to provide the user with the functionality to provide the update statements from the user screen. I want to then take the user input in a java variable for manipulation of the xml data and display the end result. The only option I have for the user is to provide the xquery updates with the following syntax: ( I need this syntax for update statements as I use a parser to convert the user input to involve fuzziness):
"insert nodes <b4>inserted child</b4> after doc('dbxml:/test.dbxml/book)/Bookstore";
Now I am trying to run these with the below Code but I am not actually getting the required output. Can somebody help me to debug or fix this code for my requirement. I use the following xml data :
<Bookstore>
<Book>
<book_ID>1</book_ID>
<title>Harry Potter and the Order of the Phoenix</title>
<subtitle/>
<author>
<author_fname>J.K.</author_fname>
<author_lname>Rowling</author_lname>
</author>
<price>9.99<;;/price>
<year_published>2004</year_published>
<publisher>Scholastic, Inc.</publisher>
<genre>Fiction</genre>
<quantity_in_stock>28997</quantity_in_stock>
<popularity>20564</popularity>
</Book>
</Bookstore>
I have track points in my code to find the mistake and I get the following ouput.
Track 3
Track 3.1
Track 3.2-----
The code I use fails to compile the xquery statement with .prepare API.
import java.io.*;
import com.sleepycat.db.*;
import com.sleepycat.dbxml.*;
public class phone{
public static void main(String[] args)
String document1 = "C:/Documents and Settings/cjmadall/Desktop/BDB/book.xml";
String docName = "book";
XmlManager myManager = null;
XmlContainer myContainer = null;
try {
myManager = new XmlManager();
myContainer = myManager.openContainer("test.dbxml");
String myQuery = "insert nodes <b4>inserted child</b4> after doc('dbxml:/test.dbxml/book)/Bookstore";
// This Works and displays the entire document-> String myQuery = "collection('test.dbxml')";
// This Doesnt Work, ends with the above output -> String myQuery = "insert nodes <newNode>Some new text</newNode> after collection("dbxml:/test.dbxml")/Bookstore";
// collection('test.dbxml')/Bookstore";
System.out.println("Track 3 ");
XmlQueryContext managerContext = myManager.createQueryContext();
System.out.println("Track 3.1 ");
// Get a context for the document queries
// XmlQueryContext documentContext = myManager.createQueryContext();
System.out.println("Track 3.2 ");
// Prepare the XmlManager query
*XmlQueryExpression managerQuery = myManager.prepare(myQuery, managerContext);*
System.out.println("Track 3.3 ");
// Perform the query.
XmlResults results = managerQuery.execute(managerContext, 0);
// Display the result set
System.out.println("Track 3.4 ");
XmlValue value;
while ((value = results.next()) != null){
System.out.println(value.asString());
System.out.println("Track 3.5 ");
results.delete();
managerQuery.delete();
// documentContext.delete();
managerContext.delete();
} catch (XmlException e) {
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} finally {
try {
if (myContainer != null) {
myContainer.close();
if (myManager != null) {
myManager.close();
} catch (XmlException ce) {
// Exception handling goes here
}//end finally
Thanks.I was using a old version of BDB and the latest version fixed this issue.

I'm having a problem updating a row on a backend database using a dataset which contains the datacolumns as parameters with a TableMapping object. I'm using this in conjunction with the ODT.net tool.
I've used this technique hundreds of times with a SQL Server backend, with no problems whatsoever. I'm not doing anything different.
Here is the SQL I'm executing:
<code>

Here is the code I'm running to try the update:
<code>
OracleDataAdapter1.TableMappings.Add("Table", "CALL")
OracleDataAdapter1.UpdateCommand.Parameters.Item(0).Value = Call11._Call.Item(0).CALLID
OracleDataAdapter1.UpdateCommand.Parameters.Item(2).Value = Call11._Call.Item(0).STANDARD
Call11._Call.Item(0).STARTTIME = DataGrid1.Item(0, 1)
Call11._Call.Item(0).STANDARD = DataGrid1.Item(0, 2)
Call11._Call.Item(0).DURATION = DataGrid1.Item(0, 3)
Call11._Call.Item(0).LESID = DataGrid1.Item(0, 4)
Call11._Call.Item(0).SERVICETYPE = DataGrid1.Item(0, 5)
Call11._Call.Item(0).MESCATEGORY = DataGrid1.Item(0, 6)
Call11._Call.Item(0).MOBILE = DataGrid1.Item(0, 7)
Call11._Call.Item(0).REGIONID = DataGrid1.Item(0, 8)
Call11._Call.Item(0).MESID = DataGrid1.Item(0, 22)
Call11._Call.Item(0).CALLID = Convert.ToInt32(TextBox1.Text)
OracleDataAdapter1.Update(Call11)
</code>
I shouldn't need to add the above lines:
<code>
OracleDataAdapter1.UpdateCommand.Parameters.Item(0).Value = Call11._Call.Item(0).CALLID
OracleDataAdapter1.UpdateCommand.Parameters.Item(2).Value = Call11._Call.Item(0).STANDARD
</code>
, but I added them to show you the value of the parms going in.
When debugging, the following is my output:
?Call11._Call.Item(0).RowState
Modified
?Call11._Call.Rows.Count
1
You can see that the rowstate is set to "Modified" and the rowcount is 1
?OracleDataAdapter1.UpdateCommand.Parameters.Item(0).Value
8612967 {Long}
[Long]: 8612967 {Long}
?OracleDataAdapter1.UpdateCommand.Parameters.Item(2).Value
"B" {String}
String: "B"
The above, are the values of the first & third parms before the "Update" statement is executed.
?OracleDataAdapter1.UpdateCommand.Parameters.Item(0).Value
{System.DBNull}
[System.DBNull]: {System.DBNull}
?OracleDataAdapter1.UpdateCommand.Parameters.Item(2).Value
{System.DBNull}
[System.DBNull]: {System.DBNull}
The above are the values of the first & third parms after the "Update" statement is executed.
<code>
OracleDataAdapter1.Update(Call11)
</code>
Notice the values are NULL. why???
Below, is the value of my TableMapping object:
?OracleDataAdapter1.TableMappings.Count
1
?OracleDataAdapter1.TableMappings.Item(0)
{System.Data.Common.DataTableMapping}
ColumnMappings: {System.Data.Common.DataColumnMappingCollection}
DataSetTable: "CALL"
SourceTable: "Table"
The datatable name of the strongly typed dataset I am using is "CALL".
When I change the update statement from:
<code>
OracleDataAdapter1.Update(Call11)
</code>
to
<code>
OracleDataAdapter1.UpdateCommand.ExecuteNonQuery()
</code>
the update works (using the latter), but returns a -1 for the records affected (-1 typically means the command can't decipher the action of the command that just took place).
I might add that I successfully executed a similiar "update" the same way via a dataset prior to what I'm trying to do here.
Why isn't the backend datasource being updated? I do not get any errors during the update statement execpt for the -1 for the records affected?I shortened the package spec to the following:
<code>
PROCEDURE proc_prUpdate
p_CALLID IN CALL.CALLID%TYPE,
p_STANDARD IN CALL.STANDARD%TYPE
</code>
I shortened the package body to the following:
<code>
PROCEDURE proc_prUpdate
p_CALLID IN CALL.CALLID%TYPE,
p_STANDARD IN CALL.STANDARD%TYPE
AS
BEGIN
update CALL set
STANDARD = p_STANDARD
where CALLID = p_CALLID;
END;
</code>
When I execute the update statement from the associated data adapter, it updates the db correctly, but still gives me a -1 for the records affected.
When I execute the exact same sql with the record inside a strongly typed dataset, it doesn't update and I still get the -1 for the records affected.
While debugging, the following output is shown for the parameter list:
?daORA.UpdateCommand.Parameters.Item(0)

?ds.Tables(0).Rows(0).RowState

Two questions:
Even though it updates successfully in the first iteration, how come I get the -1 for the records affected?
In the second iteration, how come it is not updating the backend datasource and how come I still get the -1 for the records affected? You can see that the rowstate is set to modified.
Is there a problem with the ODP.Net data provider not being able to update a backend datasource with values inside of a datatable during a "da.update" statement?
With MS SQL Server data provider, it updates the data flawlessly when I put the tables inside of a MS SQL Server. -

Here is the code I'm running to try the update:
<code>
OracleDataAdapter1.TableMappings.Add("Table", "CALL")
OracleDataAdapter1.UpdateCommand.Parameters.Item(0).Value = Call11._Call.Item(0).CALLID
OracleDataAdapter1.UpdateCommand.Parameters.Item(2).Value = Call11._Call.Item(0).STANDARD
Call11._Call.Item(0).STARTTIME = DataGrid1.Item(0, 1)
Call11._Call.Item(0).STANDARD = DataGrid1.Item(0, 2)
Call11._Call.Item(0).DURATION = DataGrid1.Item(0, 3)
Call11._Call.Item(0).LESID = DataGrid1.Item(0, 4)
Call11._Call.Item(0).SERVICETYPE = DataGrid1.Item(0, 5)
Call11._Call.Item(0).MESCATEGORY = DataGrid1.Item(0, 6)
Call11._Call.Item(0).MOBILE = DataGrid1.Item(0, 7)
Call11._Call.Item(0).REGIONID = DataGrid1.Item(0, 8)
Call11._Call.Item(0).MESID = DataGrid1.Item(0, 22)
Call11._Call.Item(0).CALLID = Convert.ToInt32(TextBox1.Text)
OracleDataAdapter1.Update(Call11)
</code>
I shouldn't need to add the above lines:
<code>
OracleDataAdapter1.UpdateCommand.Parameters.Item(0).Value = Call11._Call.Item(0).CALLID
OracleDataAdapter1.UpdateCommand.Parameters.Item(2).Value = Call11._Call.Item(0).STANDARD
</code>
, but I added them to show you the value of the parms going in.
When debugging, the following is my output:
?Call11._Call.Item(0).RowState
Modified
?Call11._Call.Rows.Count
1
You can see that the rowstate is set to "Modified" and the rowcount is 1
?OracleDataAdapter1.UpdateCommand.Parameters.Item(0).Value
8612967 {Long}
[Long]: 8612967 {Long}
?OracleDataAdapter1.UpdateCommand.Parameters.Item(2).Value
"B" {String}
String: "B"
The above, are the values of the first & third parms before the "Update" statement is executed.
?OracleDataAdapter1.UpdateCommand.Parameters.Item(0).Value
{System.DBNull}
[System.DBNull]: {System.DBNull}
?OracleDataAdapter1.UpdateCommand.Parameters.Item(2).Value
{System.DBNull}
[System.DBNull]: {System.DBNull}
The above are the values of the first & third parms after the "Update" statement is executed.
<code>
OracleDataAdapter1.Update(Call11)
</code>
Notice the values are NULL. why???
Below, is the value of my TableMapping object:
?OracleDataAdapter1.TableMappings.Count
1
?OracleDataAdapter1.TableMappings.Item(0)
{System.Data.Common.DataTableMapping}
ColumnMappings: {System.Data.Common.DataColumnMappingCollection}
DataSetTable: "CALL"
SourceTable: "Table"
The datatable name of the strongly typed dataset I am using is "CALL".
When I change the update statement from:
<code>
OracleDataAdapter1.Update(Call11)
</code>
to
<code>
OracleDataAdapter1.UpdateCommand.ExecuteNonQuery()
</code>
the update works (using the latter), but returns a -1 for the records affected (-1 typically means the command can't decipher the action of the command that just took place).
I might add that I successfully executed a similiar "update" the same way via a dataset prior to what I'm trying to do here.
Why isn't the backend datasource being updated? I do not get any errors during the update statement execpt for the -1 for the records affected?I shortened the package spec to the following:
<code>
PROCEDURE proc_prUpdate
p_CALLID IN CALL.CALLID%TYPE,
p_STANDARD IN CALL.STANDARD%TYPE
</code>
I shortened the package body to the following:
<code>
PROCEDURE proc_prUpdate
p_CALLID IN CALL.CALLID%TYPE,
p_STANDARD IN CALL.STANDARD%TYPE
AS
BEGIN
update CALL set
STANDARD = p_STANDARD
where CALLID = p_CALLID;
END;
</code>
When I execute the update statement from the associated data adapter, it updates the db correctly, but still gives me a -1 for the records affected.
When I execute the exact same sql with the record inside a strongly typed dataset, it doesn't update and I still get the -1 for the records affected.
While debugging, the following output is shown for the parameter list:
?daORA.UpdateCommand.Parameters.Item(0)
{Oracle.DataAccess.Client.OracleParameter}
ArrayBindSize: Nothing
ArrayBindStatus: Nothing

Value: "c" {String}
?ds.Tables(0).Rows(0).RowState
Modified
Two questions:
Even though it updates successfully in the first iteration, how come I get the -1 for the records affected?
In the second iteration, how come it is not updating the backend datasource and how come I still get the -1 for the records affected? You can see that the rowstate is set to modified.
Is there a problem with the ODP.Net data provider not being able to update a backend datasource with values inside of a datatable during a "da.update" statement?
With MS SQL Server data provider, it updates the data flawlessly when I put the tables inside of a MS SQL Server. -
Optimizing an update statement
I have the following update statement that I want to run everyday to perform a logical lock on records that are older than so many days. Here is my query
Update treatment
set locked_flag = 'Y'
where treatment_date <= sysdate -90
and locked_flag = 'N';
There is an index on the treatment_date and locked_flag columns. Using the <= on the date causes this index to not be used. This table has 3+ million records, and I am updating about 1,500 a day. I would really like to prevent this update statement from doing a full table scan.
Thanks.jspinelli wrote:

If you can't change the code then the advice to create a histogram on column locked_flag and an index on (locked_flag, treatment_date) could be sufficient to solve the problem,
The nicest solution, though is probably to create a function-based index:
create index treatment_fbi on treatment(case locked_flag when 'N' then treatment_date else null end);
execute dbms_stats.gather_table_stats({table_owner},'treatment',method_opt=>'for all hidden columns size 1')Then change the code to
Update treatment set
locked_flag = 'Y'
where case locked_flag when 'N' then treatment_date else null end <= sysdate - 90If I've got my case statements right, this gives you an index which is as small as it can be (it will hold the treatment_date for just those rows where locked_flag = 'N') and will allow the optimizer to see that you want to update a very small fraction of the data.
The only trouble will be if the rows to be updated are very widely scattered through the table - in which case the optimizer might think that even this optimal index isn't worth using.

Update databse from internal table statement not using index
Hi Guys,
We are updating a databse table from a file. The file has a couple of fields which have data different from what the database has (non-primary fields :). We upload the file data into an internal table and then update the database table from internal table. At a time, internal table is supposed to have 10,000 records. I did SQL trace and found that the update statement is not making use of the databse index.
Should not the update statement here be using the table index (for primary key)?
Regards,
Munish... as often there are recommendations in this forum which makes me wonder, how people overestimate their knowledge!!!
Updates and Deletes do of course use indexes, as can be seen in the SQL Trace (use explain).
Inserts don't use indexes, because in many databases inserts are just done somewhere, But also with the INSERT, the primary key is the constraint for the uniqueness condition, duplicate keys are not allowed.
Coming to the original question, what is you actually coding for the update?
What is the table, which fields are in the internal table and what are the indexes?
