SQL Update statement not executing in Filter
Hi,
I am trying to update Documents table using the query resource in a custom component. The document table is requred to upate for vault file(1 row) and for weblayout file(1 row). The java code is executing in PostConversionFilter, the sql is defined in query resource.
Query Resource is defined in componet like..
MyQResource=UPDATE Documents SET dOriginalName = ?, dFormat = ?, dFileSize = ?, dExtension = ? WHERE (dID = ? AND dIsPrimary = ? AND dIsWebFormat = ?)
This SQL executes for vault file means dIsPrimary = 1 AND dIsWebFormat = 0 however the same is not executing when for weblayout file dIsPrimary = 0 AND dIsWebFormat = 1
I putting here final satement formed, got by systematabase trace as following
For vault file:
UPDATE Documents SET dOriginalName = 'XYZ009174~1.spdf', dFormat = 'application/vnd.sealedmedia.softseal.pdf', dFileSize = 0, dExtension = 'spdf' WHERE (dID = '9559' AND dIsPrimary = 1 AND dIsWebFormat = 0)
For weblayuot file:
UPDATE Documents SET dOriginalName = 'XYZ009174~1.spdf', dFormat = 'application/vnd.sealedmedia.softseal.pdf', dFileSize = 0, dExtension = 'spdf' WHERE (dID = '9559' AND dIsPrimary = 0 AND dIsWebFormat = 1)
There is no error in logs, traces. I am using UCM 11g. in Documents table 1 row is updated for vault file only I am expecting for weblyaout updation also.
Please help what could be the possible cause?
Thanks,
Manoj

If I got your question, you state that you see a SQL statement in systemdatabase tracing, but it is not executed in the database? Btw. you should see further details (such as how much time the query took) if you turn on full verbose tracing.
I'd just go and try to execute the same queries directly in the database (e.g. in sqlplus console). My guess is that there will be no record according to the second WHERE clause...

SQL UPDATE Statement Explaination (urgent please...)
Hi,
Could anyone explain for me what this statement will do:
update KPIR KR
set ( CA ) = (
select sum(sl.RRC_CONN_STP_ATT) CA
from PV_WCEL_SERVICE_LEVEL sl, UTP_MO um
where sl.GLOBAL_ID = um.CO_GID
group by sl.STARTTIME, um.OBJECT_INSTANCE
I could not understand how the mapping between the two tables will be ("um" clause is not used in the select statement and it is used only in the "where" and "group by" arguments) What does this mean?.
The actual problem is that when I execute the above SQL statement, it was take around just 3 minutes to be implemented. But after we upgrade from Oracle 8 to Oracle 9, this statement is taking around 3 hours to be implemented.
Anyone have any idea what is the problem?Below is the plan:
KPIR table:
RNC_ID (str), PST ('YYYYMMDD_HH24'), CA (Numner)
1, 20061105_13, 0
1, 20061105_14, 0
1, 20061105_15, 0
2, 20061105_13, 0
2, 20061105_14, 0
2, 20061105_15, 0
3, 20061105_13, 0
3, 20061105_14, 0
3, 20061105_15, 0
4, 20061105_13, 0
4, 20061105_14, 0
4, 20061105_15, 0
PV_WCEL_SERVICE_LEVEL table:
GLOBAL_ID (str), STARTTIME ('YYYYMMDD_HH24'), RRC_CONN_STP_ATT (Number)
A1, 20061101_00, 9
A1, 20061101_01, 4
A1, 20061101_23, 3
A1, 20061130_23, 4
A2, 20061101_00, 3
A2, 20061101_01, 4
A2, 20061101_23, 1
A2, 20061130_23, 5
UTP_MO table;
RNC_ID (str), GLOBAL_ID (str), OBJECT_INSTANCE (str)
1, A1, <A1_NAME>
1, A2, <A2_NAME>
1, A9, <A9_NAME>
2, B1, <B1_NAME>
2, B2, <B2_NAME>
2, B9, <B9_NAME>
3, C1, <C1_NAME>
3, C2, <C2_NAME>
3, C9, <C9_NAME>
4, D1, <D1_NAME>
4, D2, <D2_NAME>
4, D9, <D9_NAME>
Now, I want to update the value of CA in table KPIR:
For instance, for RNC_ID='1' and at PST='20061105_13', the CA should equals to the sum of value RRC_CONN_STP_ATT for all GLOBAL_IDs under RNC_ID='1' and at STARTTIME '20061105_13'.
So, is this SQL UPDATE statement will do it?
update KPIR kr
set ( CA ) = (
select sum(sl.RRC_CONN_STP_ATT) CA
from PV_WCEL_SERVICE_LEVEL sl, UTP_MO um
where sl.GLOBAL_ID = um.GLOBAL_ID and kr.RNC_ID = um.RNC_ID and kr.PST = sl.STARTTIME
group by sl.STARTTIME, um.OBJECT_INSTANCE
And if so, why it is taking around 3 hours to be implemented? This issue is happened after upgrading from Oracle 8 to 9.
Really appreciate your help and thanks in advance. -
In Oracle this SQL update tatement not working but in MS SQL it works
Dear Friends,
The following sql update statement work fine in MS sql server but not working in Oracle. Can you kindly suggest, What is wrong with this statement ? and is their any other way of achieving the same in Oracle.
UPDATE INPUTSTREET SET EDIT_FLAGS=S.EDIT_FLAGS From INPUTSTREET G, INPUT_SEGBASE S Where G.GEOKEY=S.GEOKEY
This statement give error in Oralce saying - Statement not ended properly
Cheers,
VinayYou would normally write
UPDATE inputStreet g
SET edit_flags = (SELECT s.edit_flags
FROM input_segbase s
WHERE s.geokey = g.geokey)If you don't want to update all the rows in inputStreet, you can add a WHERE EXISTS clause.

Updates using single SQL Update statement.
Hi Guys,
I had an interview... and was not able to give an answer of one of the question.
Given the emp table... need to update the salary with following requirement using one SQL statement...
1. Update salary+1000 for those employees who have salary between 500 and 1000
2. Update salary+500 for those employees who have salary between 1001 and 1500
Both above requirement should be done by using only one SQL update statement... can some one tell me how to do it?update emp
set salary = case when salary between 500 and 1000
then salary + 1000
when salary between 1001 and 1500
then salary + 500
end;Regards

Regex help for SQL update statement
Hello,
need help from IPS regex guru - trying to build the signature to detect SQL update statement in HTTP requests.
1) Am I correct with regex below specified as Request-Regex?
[Uu][Pp][Dd][Aa][Tt][Ee]([%]20|[+])[\x20-\x7e]+[Ss][Ee][Tt]([%]20|[+])[\x20-\x7e]+=
2) How do I make sure that it detects 'Update' in URI and Arguments only and not in the body on entire webserver response (currently looks like the case)?1) It looks correct to me
2) Typically, the "service HTTP" engine is used to inspect requests and the "TCP string" engine is used to inspect HTTP server responses. If you only want to inspect requests, use the service HTTP engine. -
Update statement not working PL/SQL block
Hi friends,
My code is written the following way:
declare
var1 number;
var2....
Cursor c1 <select something>;
Cursor c2 <select something>
Begin
Insert into table1 <different values>;
Commit;
/* first update statement */
Update table1 set table1.col3 = (select col3 from table2 where table2.col1 = table1.col1 and table2.col2 = table1.col2);
commit ;
/* 2nd update statement */
update table1 set table1.col4 = (select col4 from table3 where table3.col1 = table1.col1 and table3.col2 = table1.col2);
commit ;
for r2 in c2 loop
update table1
end loop;
end;
This code works till 1st update statement. But after that, even if I let my code run overnight, nothing happens. There are appropriate indexes on tables where join is done. All tables are in one schema.
What could be the reason?darshilm wrote:
/* first update statement */
Update table1 set table1.col3 = (select col3 from table2 where table2.col1 = table1.col1 and table2.col2 = table1.col2);This is an unconstrained updated - meaning that it instructs the database that every single row in TABLE1 needs to be updated.
For every single row, the "update" SQL has to be executed and a SELECT performed on TABLE2.
Let's say there are a 100,000 rows in TABLE1. This means that the SELECT to find the updated value has to be executed a 100,000 times.
Let's say that there are a 200,000 rows in TABLE2. This means that each time that SELECT runs, it potentially hits 200,000 rows. Does it do it via a full table scan? Index range scan?
At what cost? Hitting the very same data set again and again and again, 100,000 times in a row.
And that is only the start of your code... and you wonder why it does not seem to finish?
Data processing in a RDBMS is about how to do the minimal amount of I/O to achieve the desired result. For example, instead of hitting TABLE2 100,000 times, you can write code to hit it once by joining it with TABLE1 and creating an "updateable view" of TABLE1 that can be updated with the join values of TABLE2.
You also seem to use PL/SQL cursors to perform row-row (and slow-by-slow) processing. This typically pulls data from the SQL engine into the PL engine and then push that very same data from the PL engine to the SQL engine.. It is a lot faster and more efficient (and scalable) to rather stay inside the SQL engine and do data set processing there (as oppose to row-by-row on the client side).
Performance in a RDBMS is primarily determined by the designer and the developer... are functions of how well designed the data model is, and how well designed and written the code is. -
Problem in Update statement using Execute Immediate
Hi All,
I am facing problem in update statement.
I am creating dynamic sql and use "execute immediate" statement to execute a update statement.
But it is not updating any thing there in the table.
I have created a query like :
update_query='Update '|| Table_Name ||' t set t.process_status =''Y'' where t.tid=:A';
Execute immediate update_query using V_Id;
commit;
But it is not updating the table.
I have a question , is execute immediate only does insert and delete?
Thanks

We started with Etbin's idea to create a table from the ext table so that we can index and reference easier than an external table, so we did the following:

Table created.
SQL> desc ext_person

Using named parameters with an sql UPDATE statement
I am trying to write a simple? application on my Windows 7 PC using HTML, Javascript and Sqlite. I have created a database with a 3 row table and pre-populated it with data. I have written an HTML data entry form for modifying the data and am able to open the database and populate the form. I am having trouble with my UPDATE function. The current version of the function will saves the entry in the last row of the HTML table into the first two rows of the Sqlite data table -- but I'm so worn out on this that I can't tell if it is accidental or the clue I need to fix it.
This is the full contents of the function . . .
updateData = new air.SQLStatement();
updateData.sqlConnection = conn;
updateData.text = "UPDATE tablename SET Gsts = "Gsts, Gwid = :Gwid, GTitle = :GTitle WHERE GId = ":GId;
var x = document.getElementsById("formname");
for (var i = 1, row, row = x.rows[i]; i++) {
updateData.parameters[":GId"] = 1;
for (var j = 0, col; col=row.cells[j]; j++) {
switch(j) {
case 0: updateData.parameters[":GTitle"] = col.firstChild.value; break;
case 1: updateData.parameters[":Gsts"] = col.firstChild.value; break;
case 2: updateData.parameters[":Gwid"] = col.firstChild.value; break;
Note: When I inspect the contents of the col.firstChild.value cases, they show the proper data as entered in the form -- it just isn't being updated into the proper rows of the Sqlite table.
Am I using the named parameters correctly? I couldn't find much information on the proper use of parameters in an UPDATE statement.Thank you for the notes. Yes, the misplaced quotes were typos. I'm handtyping a truncated version of the function so I don't put too much info in the post. And yes, i = 1 'cuz the first rows of the table are titles. So the current frustration is that I seem to be assigning all the right data to the right parameters but nothing is saving to the database.
I declare updateData as a variable at the top of the script file
Then I start a function for updating the data which establishes the sql connection as shown above.
The correctly typed.text statement is:
updateData.text = "UPDATE tablename SET Gsts=:Gsts, Gwid=:Gwid, GTitle=:GTitle WHERE GId=:GId";
(The data I'm saving is entered in text boxes inside table cells.) And the current version of the loop is:
myTable = document.getElementById("GaugeSts");
myRows= myTable.rows;
for(i=1, i<myRows.length, i++) {
updateData.parameters[":GId"]=i;
for(j=0; j<myRows(i).cells.length, j++) {
switch(y) {
case 0: updateData.parameters[":GTitle"]=myrows[i].cells[y].firstChild.value; break;
case 1: updateData.parameters[":Gsts"]=myrows[i].cells[y].firstChild.value; break;
case 2: updateData.parameters[":Gwid"]=myrows[i].cells[y].firstChild.value; break;
updateData.execute;
The whole thing runs without error and when I include the statements to check what's in myrows[i].cells[y].firstChild.value, I'm seeing that the correct data is being picked up for assignment to the parameters and the update. I haven't been able to double check that the contents of the parameters are actually taking the data 'cuz I don't know how to extract the data from the parameters. ( The only reference I've found so far has said that it is not possible. I'm still researching that one.) I've also tried moving the position of the updateData execution statement to several different locations in the loop andstill nothing updates.
I am using a combination of air.Introspector.Console.log to check the results of code and I'm using Firefox's SQlite manager to handle the database. The database is currently sitting on the Desktop to facilitate testing and I have successfully updated/changed data in this table through the SQLite Manager so I don't think I'm having permission errors and, see below, I have another function successfully saving data to another table.
I currently have another function that uses ? for the parametersin the .text of a INSERT/REPLACE statement and that one works fine. But, only one line of data is being saved so there is no loop involved. I tried changing the UPDATE statement in this function to the INSERT/REPLACE just to make something save back to the database but I can't make that one work either.I've a (And, I've tried so many things now, I don't even remember what actually saved something --albeit incorrectly --to the database in one of my previous iterations with the for loops.)
I'm currently poring through Sqlite and Javascript tomes to see if I can find what's missing but if anything else jumps out at you with the corrected code, I'd appreciate some ideas.

Use of ROWID in SQL Update Statement
Hi All,
I have an update statement which uses the rowid column to perform the selection on the target table. Given that a rowid represents the physical location of a row on disk we know that this reference can change when various activities are performed on the database/table/row etc...
Here is an example of the statement I am issuing:
UPDATE tabA outertab SET col1 = 'Value'
WHERE EXISTS (SELECT 1 FROM tabA innertab WHERE outertab.ROWID = outertab.ROWID AND ...)
Obviously the inner query is more complicated and uses other tables etc... but for the purposes of the example we dont need to include the detail.
My question is: When using rowid in a single SQL statement as a reference from a subquery to the outer statement is there a risk that external activities can change the rowid and those changes be reflected within the database session that my query is executing thus causing an inconsistency between the inner and outer SQL clause?
In response to the question which will follow this post: "Why don't you just use a PK", We would like to avoid maintaining a PK on the table as we are talking about very large volumes of data and we dont want to have to issue a call to a sequence if we can avoid it when we are inserting the data. If however there is a risk that this Update statement could fail or update the wrong rows then we may have to use a PK.
I know there is a lot of threads about this but I havnt been able to find one that someone has answered with any kind of confidence or clarity, any help would be much appreciated.
Thanks
Keith

Docs
A row's assigned rowid remains unchanged unless the row is exported and imported using the Import and Export utilities. When you delete a row from a table and then commit the encompassing transaction, the deleted row's associated rowid can be assigned to a row inserted in a subsequent transaction. -

Sql Update Statement (complex)
Hi ,
A very good morning to all.
I am stuck in a problem , and i really hope for solutiion.
I have a dimension table (DIM_CAR) for which i need to write a update statement.
My table structure is :
C_ID Startdate EndDate
7546343 2012-05-29 00:00:00 NULL
7546343 2012-05-18 00:00:00 2012-05-29 00:00:00
7546343 2012-05-14 00:00:00 2012-05-18 00:00:00
7546343 2012-05-10 00:00:00 2012-05-10 00:00:00
7546343 2012-05-10 00:00:00 2012-05-14 00:00:00
7546343 2012-03-22 00:00:00 2012-03-22 00:00:00
7546343 2012-03-15 00:00:00 2012-03-22 00:00:00
7546343 2012-02-02 00:00:00 2012-03-15 00:00:00
7546343 2012-01-31 00:00:00 2012-02-02 00:00:00
Now the scenario is Whenever any update comes in car , then it closes the previous record and open a new record(SCD)
For e.g the 1st update comes on 2012-02-02 , so it closes the last record (by putting 2012-02-02) in end date and open a new record by putting 2012-02-02 in startdate. Then update comes in 2012-03-15 and so on. The last record is for 2012-05-29 which is
still open as there is no update after that,
so whenever any update come it opens a new record with startdate value is extract date and enddate value NULL and closes the previous. Then after another update , that NULL value is replace by the new date and another record opens.
My prob is if you will closely analyse the dates , then there are some records missing in the above table due to which there are discrepencies in dates.
E.g. If u see the 6th row, startdate is 2012-03-22 and enddate is also 2012-03-22. But here in this case the enddate should be 2012-05-10(which is next update)
I need to write a sql script to update enddates with the latest update startdate in my table. I have 60000 of C_id which are affected.
COULD ANYONE plz Help.. I knw its difficult but u can give a try ..........Plz ask if anyone requires more info.
AbhishekPlease post DDL, so that people do not have to guess what the keys, constraints, Declarative Referential Integrity, data types, etc. in your schema are. Learn how to follow ISO-11179 data element naming conventions and formatting rules. Temporal data should
use ISO-8601 formats. Code should be in Standard SQL as much as possible and not local dialect.
This is minimal polite behavior on SQL forums.
>> I have a dimension table (DIM_CAR) for which I need to write a update statement. My table structure is : <<
NO! This is a picture of the data; it is not DDL! Is this what you would have posted if you had manners?
CREATE TABLE Foobars
(c_id CHAR(7) NOT NULL,
foo_start_date DATE NOT NULL,
PRIMARY KEY (c_id, foo_start_date), -- my guess!!
CHECK (foo_start_date < foo_end_date),-- another guess!
foo_end_date DATE);
INSERT INTO Foobar
VALUES
('7546343', '2012-05-29', 'NULL),
('7546343', '2012-05-18', '2012-05-29'),
('7546343', '2012-05-14', '2012-05-18'),
('7546343', '2012-05-10', '2012-05-10'),
('7546343', '2012-05-10', '2012-05-14'),
('7546343', '2012-03-22', '2012-03-22'),
('7546343', '2012-03-15', '2012-03-22'),
('7546343', '2012-02-02', '2012-03-15'),
('7546343', '2012-01-31', '2012-02-02');
Now the scenario is Whenever any update comes in car, then it closes the previous record [sic: rows are not records! Please learn basic terms] and open a new record [sic](SCD).
What is “SCD” and why do you think it is meaningful to us? Here is an article on this topic.
Modifying Contiguous Time Periods
This article explains how to modify contiguous time periods that were described in Joe Celko’s article 'Contiguous Time Periods in SQL'. Joe describes the table itself that he calls the 'Kuznetsov History Table'. He explains how it is used to store contiguous
time intervals with constraint to ensure that the date periods really are contiguous, The editor suggested that I give a brief description of how to modify the data in the History table as this may not be entirely obvious.
When trusted constraints enforce data integrity, the data is guaranteed to be valid at the end of any statement, even if it is not committed. When we modify contiguous time periods, in order to get from one valid state to another we may need to insert a row
and update another one, or we may need to delete a row and update another one. This is one of those cases when MERGE really shines – it allows us to get from one valid state to another in one statement, inserting, updating, and deleting rows as needed.
CREATE TABLE Tasks
(task_id INT NOT NULL,
task_score INTEGER NOT NULL,
current_start_date DATE NOT NULL,
current_end_date DATE NOT NULL,
previous_end_date DATE NULL,
CONSTRAINT PK_Tasks_task_id_current_end_date
PRIMARY KEY (task_id, current_end_date),
CONSTRAINT UNQ_Tasks_task_id_previous_end_date
UNIQUE (task_id, previous_end_date),
CONSTRAINT FK_Tasks_task_id_previous_end_date
FOREIGN KEY (task_id, previous_end_date)
REFERENCES Tasks (task_id, current_end_date),
CONSTRAINT CHK_Tasks_previous_end_date_NotAfter_current_start_date
CHECK (previous_end_date <= current_start_date),
CONSTRAINT CHK_Tasks_current_start_date_Before_current_end_date
CHECK (current_start_date < current_end_date)
Some Easy Modifications.
It is easy to begin a new series of time periods
INSERT INTO Tasks
(task_id, task_score, current_start_date, current_end_date, previous_end_date)
VALUES (1, 100, '2010-1002', '2010-1023', NULL),
(1, 80, '2010-1023', '2010-11-03', '2010-1023');
It is just as easy to continue adding periods to the end of the series.
INSERT INTO Tasks
(task_id, task_score, current_start_date, current_end_date, previous_end_date)
VALUES(1, 98, '2010-11-20', '2010-11-25', '2010-11-03'),
(1, 75, '2010-11-26', '2010-11-27', '2010-11-25');
Deleting one or more rows from the end is just as easy, and we shall skip the example. As we have seen, it is easy to perform typical, the most common operations against history of periods.
However, some other operations are less easy and need more explanations. Now that we have enough test data, let us move on to more complex examples. Here is the test data at this moment:
Adding periods to the beginning.
Each series of periods has exactly one first period – this is enforced by the following constraint: Unique_task_id_and_previous_end_date
As a result, when we are inserting one or more periods to the beginning of the series, we have to update the period that used to be the first, as follows:
MERGE INTO Tasks
USING (VALUES (1, 98, '2009-03-01', '2009-03-06', NULL),
(1, 100, '2010-10-02', '2010-10-23', '2009-03-06')
) AS Source (task_id, task_score, current_start_date, current_end_date, previous_end_date)
ON Tasks.task_id = Source.task_id
AND Tasks.current_start_date = Source.current_start_date
WHEN MATCHED
THEN UPDATE
SET task_score = Source.task_score,
current_start_date = Source.current_start_date,
current_end_date = Source.current_end_date,
previous_end_date = Source.previous_end_date
WHEN NOT MATCHED
THEN INSERT (task_id, task_score, current_start_date, current_end_date, previous_end_date)
VALUES (Source.task_id, Source.task_score, Source.current_start_date,
Source.current_end_date, Source.previous_end_date);
Now we will verify that our test data looks as expected, with a new row at the beginning, and previous_end_date column is modified to point to the new row for the row that used to be the first before this modification:
We are also going to discuss some other scenarios, such as adding/deleting periods in the middle of the series. In all these cases we shall be using MERGE, and the DML looks quite similar, so let us wrap it up in a stored procedure.
CREATING A STORED PROCEDURE
The following code implements this merging functionality with a stored procedure that uses a table to hold teh new rows:
CREATE TABLE NewTasks
(task_id INTEGER NOT NULL,
task_score INTEGER NOT NULL,
current_start_date DATE NOT NULL,
current_end_date DATE NOT NULL,
previous_end_date DATE NULL,
deletion_flg CHAR(1));
CREATE PROCEDURE MergeNewTasks
AS BEGIN
MERGE INTO Tasks
USING (SELECT task_id, task_score, current_start_date, current_end_date, previous_end_date, deletion_flg
FROM NewTasks) AS Source
ON Tasks.task_id = Source.task_id
AND Tasks.current_start_date = Source.current_start_date
WHEN MATCHED AND deletion_flg = 'Y'
THEN DELETE
WHEN MATCHED
THEN UPDATE SET
task_score = Source.task_score,
current_start_date = Source.current_start_date,
current_end_date = Source.current_end_date,
previous_end_date = Source.previous_end_date
WHEN NOT MATCHED
THEN INSERT (task_id, task_score, current_start_date, current_end_date, previous_end_date)
VALUES (Source.task_id, Source.task_score, Source.current_start_date, Source.current_end_date, Source.previous_end_date);
END;
Let us use this stored procedure.
Filling a gap in the middle of the series
The following code fills the gap on November 25th.
CREATE TABLE NewTasks (..);
INSERT INTO NewTasks
(task_id, task_score, current_start_date, current_end_date, previous_end_date, deletion_flg)
VALUES (1, 75, '2010-11-25', '2010-11-26', '2010-11-25', 'N'),
(1, 80, '2010-11-26', '2010-11-27', '2010-11-26', 'N');
EXEC MergeNewTasks NewTasks = NewTasks;
Here is the data after this modification, with a period added in the middle fo the series:
Deleting a period in the middle of the series
The following code deletes the period added in the previous example.
CREATE TABLE NewTasks (..);
INSERT INTO NewTasks
(task_id, task_score, current_start_date, current_end_date,
previous_end_date, deletion_flg)
VALUES (1, 75, '2010-11-25', '2010-11-26', '2010-11-25', 'Y'),
(1, 80, '2010-11-26', '2010-11-27', '2010-11-25', 'N');
EXEC MergeNewTasks;
Here is the data after this modification:
Inserting two periods in the middle, and adjusting an exaisting period to make room for them. This is the last and most complex example involving our stored procedure:
CREATE TABLE NewTasks (..);
INSERT INTO NewTasks
(task_id, task_score, current_start_date, current_end_date, previous_end_date, deletion_flg)
VALUES (1, 98, '2010-11-20', '2010-11-22', '2010-11-03', 'N'),
(1, 75, '2010-11-22', '2010-11-23', '2010-11-22', 'N'),
(1, 98, '2010-11-23', '2010-11-25', '2010-11-23', 'N');
EXEC MergeNewTasks;

I need to perform bulk updates on my tables using SQL. The tables are really very big and most of updates occur on couple of million records. As such the process is time consuming and very slow. Is there anything I could do to fine tune these update statements? Please advise. Some of the same SQL statements I use are as follows
update test set gid=1 where gid is null and pid between 0 and 1;
