Slow inserts into partitioned table

I am having trouble inserting into a simple partitioned table after an upgrade to 11.2.0.3. I'm seeing insert speeds of subsecond up to 10 and 12 seconds. We have pre created the partitions for this table (and all children via reference partitioning). We have gathered dictionary and static object stats as well as statistics on all partitions.
Queries against the dictionary are incredibly slow as well and showing very high io.
Any help would be greatly appreciated. Thank you for your time.

Constantly inserting into large table with unique index... Guidance?

Hello all;
So here is my world. We have central to our data monitoring system an oracle database running Oracle Standard One (please don't laugh... I understand it is comical) licensing.
This DB is about 1.7 TB of small record data.
One table in particular (the raw incoming data, 350gb, 8 billion rows, just in the table) is fed millions of rows each day in real time by two to three main "data collectors" or what have you. Data must be available in this table "as fast as possible" once it is received.
This table has 6 columns (one varchar usually empty, a few numerics including a source id, a timestamp and a create time).
The data is collect in chronological order (increasing timestamp) 90% of the time (though sometimes the timestamp may be very old and catch up to current). The other 10% of the time the data can be out of order according to the timestamp.
This table has two indexes, unique (sourceid, timestamp), and a non unique (create time). (FYI, this used to be an IOT until we had to add the second index on create time, at which point a secondary index on create time slowed the IOT to a crawl)
About 80% of this data is removed after it ages beyond 3 months; 20% is retained as "special" long term data (customer pays for longer raw source retention). The data is removed using delete statements. This table is never (99.99% of the time) updated. The indexes are not rebuilt... ever... as a rebuild is about a 20+ hour process, and without online rebuilds since we are standard one, this is just not possible.
Now what we are observing is that the inserts into this table
- Inserts are much slower based on a "wider" cardinality of the "sourceid" of the data being inserted. What I mean is that 10,000 inserts for 10,000 sourceid (regardless of timestamp) is MUCH, MUCH slower than 10,000 inserts for a single sourceid. This makes sense to me, as I understand it that oracle must inspect more branches of the index for uniqueness, and more different physical blocks will be used to store the new index data. There are about 2 million unique sourceId across our system.
- Over time, oracle is requesting more and more ram to satisfy these inserts in a timely matter. My understanding here is that oracle is attempting to hold the leafs of these indexes perpetually buffers. Our system does have a 99% cache hit rate. However, we are seeing oracle requiring roughly 10GB extra ram per quarter to 6 months; we're at about 50gb of ram just for oracle already.
- If I emulate our production load on a brand new, empty table / indexes, performance is easily 10x to 20x faster than what I see when I do the same tests with the large production copies of data.
We have the following assumption: Partitioning this table based on good logical grouping of sourceid, and then timestamp, will help reduce the work required by oracle to verify uniqueness of data, reducing the amount of data that must be cached by oracle, and allow us to handle our "older than 3 month" at a partition level, greatly reducing table and index fragmentation.
Based on our hardware, its going to be about a million dollar hit to upgrade to Enterprise (with partitioning), plus a couple hundred thousand a year in support. Currently I think we pay a whopping 5 grand a year in support, if that, total oracle costs. This is going to be a huge pill for our company to swallow.
What I am looking for guidance / help on, should we really expect partitioning to make a difference here? I want to get that 10x performance difference back we see between a fresh empty system, and our current production system. I also want to limit oracles 10gb / quarter growing need for more buffer cache (the cardinality of sourceid does NOT grow by that much per quarter... maybe 1000s per quarter, out of 2 million).
Also, please I'd appreciate it if there were no mocking comments about using standard one up to this point :) I know it is risky and insane and maybe more than a bit silly, but we make due with what we have. And all the credit in the world to oracle that their "entry" level system has been able to handle everything we've thrown at it so far! :)
Alright all, thank you very much for listening, and I look forward to hear the opinions of the experts.

Hello,
Here is a link to a blog article that will give you the right questions and answers which apply to your case:
http://jonathanlewis.wordpress.com/?s=delete+90%25
As far as you are deleting 80% of your data (old data) based on a timestamp, then don't think at all about using the direct path insert /*+ append */ as suggested by one of the contributors to this thread. The direct path load will not re-use any free space made by the delete. You have two indexes:
(a) unique index (sourceid, timestamp)
(b) index(create time)
Your delete logic (based on arrival time) will smatch your indexes as far as you are always deleting the left hand side of the index; it means you will have what we call a right hand index - In other words, the scattering of the index key per leaf block is certainly catastrophic (there is an oracle iternal function named sys_op_lidbid that will allow you to verify this index information). There is a fairly chance that your two indexes will benefit from a coalesce as already suggested:
           ALTER INDEX indexname COALESCE;This coalesce should be investigated to be done on a regular basis (may be after each 80% delete) You seem to have several sourceid for one timestamp. If the answer is yes you should think about compressing this index
    create index indexname (sourceid, timestamp) compress;
or
    alter index indexname rebuild compress;     You will do it only once. Your index will have a smaller size and may be more efficient than it is actually. The index compression will add an extra CPU work during an insert but it might help improving the overal insert process.

Selecting Records from 125 million record table to insert into smaller table

Oracle 11g
I have a large table of 125 million records - t3_universe. This table never gets updated or altered once loaded, but holds data that we receive from a lead company.
I need to select records from this large table that fit certain demographic criteria and insert those into a smaller table - T3_Leads - that will be updated with regard to when the lead is mailed and for other relevant information.
My question is what is the best (fastest) approach to select records from this 125 million record table to insert into the smaller table. I have tried a variety of things - views, materialized views, direct insert into smaller table...I think I am probably missing other approaches.
My current attempt has been to create a View using the query that selects the records as shown below. Then use a second query that inserts into T3_Leads from this View V_Market. This is very slow. Can I just use an Insert Into T3_Leads with this query - it did not seem to work with the WITH clause?    My Index on the large table is t3_universe_composite and includes zip_code, address_key, household_key.
CREATE VIEW V_Market as
WITH got_pairs    AS
     SELECT /*+ INDEX_FFS(t3_universe t3_universe_composite) */ l.zip_code, l.zip_plus_4, l.p1_givenname, l.surname, l.address, l.city, l.state, l.household_key, l.hh_type as l_hh_type, l.address_key, l.narrowband_income, l.p1_ms, l.p1_gender, l.p1_exact_age, l.p1_personkey, e.hh_type as filler_data, 1.p1_seq_no, l.p2_seq_no
     ,      ROW_NUMBER () OVER ( PARTITION BY l.address_key
                                  ORDER BY      l.hh_verification_date DESC
                  ) AS r_num
     FROM   t3_universe e
     JOIN   t3_universe l ON
            l.address_key = e.address_key
            AND l.zip_code = e.zip_code
          AND   l.p1_gender != e.p1_gender
             AND   l.household_key != e.household_key
             AND l.hh_verification_date >= e.hh_verification_date
SELECT *
FROM got_pairs
where l_hh_type !=1 and l_hh_type !=2 and filler_data != 1 and filler_data != 2 and zip_code in (select * from M_mansfield_02048) and p1_exact_age BETWEEN 25 and 70 and narrowband_income >= '8' and r_num = 1
Then
INSERT INTO T3_leads(zip, zip4, firstname, lastname, address, city, state, household_key, hh_type, address_key, income, relationship_status, gender, age, person_key, filler_data, p1_seq_no, p2_seq_no)
select zip_code, zip_plus_4, p1_givenname, surname, address, city, state, household_key, l_hh_type, address_key, narrowband_income, p1_ms, p1_gender, p1_exact_age, p1_personkey, filler_data, p1_seq_no, p2_seq_no
from V_Market;

I had no trouble creating the view exactly as you posted it. However, be careful here:
and zip_code in (select * from M_mansfield_02048)
You should name the column explicitly rather than select *. (do you really have separate tables for different zip codes?)
About the performance, it's hard to tell because you haven't posted anything we can use, like explain plans or traces but simply encapsulating your query into a view is not likely to make it any faster.
Depending on the size of the subset of rows you're selecting, the /*+ INDEX hint may be doing your more harm than good.

Oracle 10g performance degrades while concurrent inserts into a table

Hello Team,
I am trying to insert into single table via multiple threads, Some of these threads perform reasonably well but some will take really longer time, As the time goes on performance drastically degrades (even down by 500 to 600 times). With AWR report i see that there quite huge number of buffer gets there. I am not sure how can i reduce those. If i ran on a single thread this operation is consistent.
I tried quite a few options like
1. Increasing SGA Memory
2. Moving redo logs to another disk drive.
3. Trying it on a empty table
4. Trying it on a table which has huge data (4 Million rows)
5. I have even tried partitioning the table with HASH algoritm
Note: Each thread i am pupming equal amount of data (let say 25K rows).
Can any body suggest me a clue what could be the culprit here.
Thanks in Advance

How can I insert into a table other than the default table in a form

Hi,
I want to insert into a table with some fields value of a form of another table. I have written insert code On successful submission of that form, but after submit it gives the following error
An unexpected error occurred: ORA-06502: PL/SQL: numeric or value error (WWV-16016)
My code is like this
declare
l_trn_id number;
l_provider_role varchar2(3);
l_provider_id varchar2(10);
begin
l_trn_id := p_session.get_value_as_number(p_block_name=>'DEFAULT',p_attribute_name=>'A_TRANSACTION_ID');
l_provider_id := p_session.get_value_as_varchar2(p_block_name=>'DEFAULT',p_attribute_name=>'A_PROVIDER1');
l_PROVIDER_ROLE := p_session.get_value_as_varchar2(p_block_name=>'DEFAULT',p_attribute_name=>'A_PROVIDER_ROLE1');
if (l_provider_role is not null) and (l_provider_id is not null) then
insert into service_provider_trans_records(service_provider_id,transaction_id,role_type_id)
values(l_provider_id, l_trn_id, l_provider_role);
commit;
end if;
end;
Where 'PROVIDER1' and 'PROVIDER_ROLE1' are not table fields.
How can do that or why this error comes ? Any idea?
Thanks

Hi,
When do you get this error? Is it while running or while creating the form.
Here is a sample code which inserts a non-database column dummy into a table called dummy. This is done in successful procedure.
declare
l_dummy varchar2(1000);
begin
l_dummy := p_session.get_value_as_varchar2(p_block_name=>'DEFAULT',
p_attribute_name=>'A_DUMMY');
insert into sjayaram903_1g.dummy values(l_dummy);commit;
end;
Please check in your case if the size of the local variable is enough to hold the values being returned.
Thanks,

Inserting into a table which is created "on the fly" from a trigger

Hello all,
I am trying to insert into a table from a trigger in Oracle form. The table name however, is inputted by the user in am item form.
here is what the insert looks like:
insert into :table_name
values (:value1, :value2);
the problem is that forms does not recognize ::table_name. If I replace :table_name with an actual database table, it works fine. However, I need to insert to a table_name based from oracle form item.
By the way, the table|_name is built on the fly using a procedure before I try to insert into it.
Any suggestion on how can I do that? My code in the trigger is:
declare
dm_drop_tbl(:table_name,'table) // a call to an external procedure to drop the table
dm_create_tbl(:table_name,'att1','att2');
insert into :table_name
values (:value1, :value2);
this give me an error:
encounter "" when the symbol expecting one.....

Hi ,
You should use the FORMS_DDL built_in procedure. Read the on-line documentation of forms ...

Problem while inserting into a table which has ManyToOne relation

Problem while inserting into a table *(Files)* which has ManyToOne relation with another table *(Folder)* involving a attribute both in primary key as well as in foreign key in JPA 1.0.
Relevent Code
Entities:
public class Files implements Serializable {
@EmbeddedId
protected FilesPK filesPK;
private String filename;
@JoinColumns({
@JoinColumn(name = "folder_id", referencedColumnName = "folder_id"),
@JoinColumn(name = "uid", referencedColumnName = "uid", insertable = false, updatable = false)})
@ManyToOne(optional = false)
private Folders folders;
public class FilesPK implements Serializable {
private int fileId;
private int uid;
public class Folders implements Serializable {
@EmbeddedId
protected FoldersPK foldersPK;
private String folderName;
@OneToMany(cascade = CascadeType.ALL, mappedBy = "folders")
private Collection<Files> filesCollection;
@JoinColumn(name = "uid", referencedColumnName = "uid", insertable = false, updatable = false)
@ManyToOne(optional = false)
private Users users;
public class FoldersPK implements Serializable {
private int folderId;
private int uid;
public class Users implements Serializable {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Integer uid;
private String username;
@OneToMany(cascade = CascadeType.ALL, mappedBy = "users")
private Collection<Folders> foldersCollection;
I left out @Basic & @Column annotations for sake of less code.
EJB method
public void insertFile(String fileName, int folderID, int uid){
FilesPK pk = new FilesPK();
pk.setUid(uid);
Files file = new Files();
file.setFilename(fileName);
file.setFilesPK(pk);
FoldersPK folderPk = new FoldersPK(folderID, uid);
// My understanding that it should automatically handle folderId in files table,
// but it is not…
file.setFolders(em.find(Folders.class, folderPk));
em.persist(file);
It is giving error:
Internal Exception: java.sql.SQLException: Field 'folderid' doesn't have a default value_
Error Code: 1364
Call: INSERT INTO files (filename, uid, fileid) VALUES (?, ?, ?)_
_ bind => [hello.txt, 1, 0]_
It is not even considering folderId while inserting into db.
However it works fine when I add folderId variable in Files entity and changed insertFile like this:
public void insertFile(String fileName, int folderID, int uid){
FilesPK pk = new FilesPK();
pk.setUid(uid);
Files file = new Files();
file.setFilename(fileName);
file.setFilesPK(pk);
file.setFolderId(folderId) // added line
FoldersPK folderPk = new FoldersPK(folderID, uid);
file.setFolders(em.find(Folders.class, folderPk));
em.persist(file);
My question is that is this behavior expected or it is a bug.
Is it required to add "column_name" variable separately even when an entity has reference to ManyToOne mapping foreign Entity ?
I used Mysql 5.1 for database, then generate entities using toplink, JPA 1.0, glassfish v2.1.
I've also tested this using eclipselink and got same error.
Please provide some pointers.
Thanks

Hello,
What version of EclipseLink did you try? This looks like bug https://bugs.eclipse.org/bugs/show_bug.cgi?id=280436 that was fixed in EclipseLink 2.0, so please try a later version.
You can also try working around the problem by making both fields writable through the reference mapping.

Diffrence between backend insert and front end insert into a table.

I am developing a conversion program for tax exemption. For this program only ZX_EXEMPTIONS table is used to populate the data and we got confirmation from Oracle also regarding this.For inserting the data into this table we are taking the max of tax_exemption_id which is pk for this table and adding one to it and inserting into the table. But problem here is after inserting from back end we are not able to insert from front end.
It seems backend data is holding the tax_exemption_id which is suppose to reserve by front end data.Please explain the different behavior of populating of tax_exemption_id from front end and back end.

Hi,
i think the problem is that you are using max-value + 1 for tax_exemption_id. But as ZX_EXEMPTIONS is using sequence ZX_EXEMPTIONS_S
for primary key generation, you encounter situation that you are increasing PK Id for this table without increasing sequence value.
When trying to insert rows from front end - which probably uses sequence value - it tries to use a sequence value already used by your backend
process (which generated it by Maxvalue + 1) and would then encounter a primary key violation.
I think you should use sequence mentioned above to generate your PK Ids in backend process as well. And before doing so, check current value
of ZX_EXEMPTIONS_S, as you might need to rebuild the sequence in order to select nextval sucessfully for both frontend and backend.

How can I get a count at the same time I am inserting into another table

I have a requirement where I have to find out the count(number of records inserted into another table) at the same time I insert into the table:

INSERT INTO A
SELECT * FROM B
how can I store the count into any variable while doing above statement
Please advice

How to insert into a table with a nested table which refer to another table

Hello everybody,
As the title of this thread might not be very understandable, I'm going to explain it :
In a context of a library, I have an object table about Book, and an object table about Subscriber.
In the table Subscriber, I have a nested table modeling the Loan made by the subscriber.
And finally, this nested table refers to the Book table.
Here the code concerning the creation of theses tables :
Book :
create or replace type TBook as object
number int,
title varchar2(50)
Loan :
create or replace type TLoan as object
book ref TBook,
loaning_date date
create or replace type NTLoan as table of TLoan;
Subscriber :
create or replace type TSubscriber as object
sub_id int,
name varchar2(25)
loans NTLoan
Now, my problem is how to insert into a table of TSubscriber... I tried this query, without any success...
insert into OSubscriber values
*(1, 'LEVEQUE', NTLoan(*
select TLoan(ref(b), '10/03/85') from OBook b where b.number = 1)
Of course, there is an occurrence of book in the table OBook with the number attribute 1.
Oracle returned me this error :
SQL error : ORA-00936: missing expression

I want to do an insert into both tables via the application and also via the same page (with one button link). I have made a form to add an employee with an add button - adding an employee is no problem.
Now, on the same page, I have added a html text area in another region, where the user can write a note. But how do I get the note to insert into the Notes table when the user clicks the add button?
In other words, when the user clicks 'add', the employee information should be inserted into the Employees table and the note should be inserted into the Notes table.
How do I go about doing this?
Thanks.

My pl/sql code is the same as posted earlier.
Upon inserting data into the forms and clicking the add button, I get this error...
ORA-06550: line 1, column 102: PL/SQL: ORA-00904: "NOTES": invalid identifier ORA-06550: line 1, column 7: PL/SQL: SQL Statement ignored
     Error      Unable to process row of table EMPLOYEES.
Is there something wrong with the pl/sql code or is it something else?

Record not inserting into the table through Forms 10g

Hi all,
I have created a form in 10g(10.1.2.0.2) based on just one table that has 4 columns(col1, col2, col3, col4).
Here col1, col2 and col3 are VARCHAR2 and col4 is date and all the columns are not null columns(There are no primary and foriegn key constrains, which means duplicates are allowed).
My form contains 2 blocks where block 1 has one text item (col1) and 3 buttons (Delete, Save, Exit).
And block2 is a database block and has col2,col3,col4 which are in tabluar layout frame displaying 10 records.
When the form is opened the cursor has to be in block1.col1 for querrying. Here i enter a value in col1, and then when I click on col2 in the block2, then I put execute_query in new_block_instance of block2, which displays the records.
The block2 properties are not updatable, insertable and query is allowed.
Everything is working good until here. But here in the block2 when I want to insert another record into the table, by navigating all the way down to the last empty record and entering the new values for col2, col3 and col4 And then Ctrl+S will display the message "*FRM-40400: Transaction complete: 1 record applied and saved.*" But actually the record is not inserted into the table.
I also disabled the col4 by setting the Enabled property to No, since while inserting new record the date have to be populated into it and it shouldnt be changed by the user. And im populating the sysdate into the new record by setting Intial Value property to *$$DATE$$*.
And another requirement which I could not work arround here is that, the col3 also should be populated with the username of the user while inserting.
please help me...

Hi Sarah,
I do not want to update the existing record. So I kept Udate Allowed to No in property palette for the items in block2.
Do I have to do this property at block level also?
I'm inserting a new record here.

Fetch data from one table and insert into two tables in desired format

I have similar to the following data in a table and it is not normalized. The groupID is being used to group two records of similar nature.
DECLARE @OldDoc TABLE (oldDocID INT, groupID INT, deptID INT)
INSERT INTO @OldDoc (oldDocID, groupID) VALUES (1, NULL, 111),(2,NULL,111),(3,1,111),(4,NULL,333),(5,1,222),(6,NULL,333),(7,2,222),(8,2,333),(9,NULL,111),(10,3,222),(11,NULL,333),(12,3,444)
I need to process the data from the above table (@OldDoc) and write into two new tables (@NewDoc and @NewDocGroup) as follows.
oldDocID should be stored as newDocID when inserting to @NewDoc table. Only records with groupID NULL and one record (first one) per group should be considered (For example, oldDocID 5 is not considered as 3 and 5 belong to the same groupID 1) for insertion.
DECLARE @NewDoc TABLE (newDocID INT)
INSERT INTO @NewDoc (newDocID) VALUES (1),(2),(3),(4),(6),(7),(9),(10),(11)
All records from @OldDoc should be considered for insertion into @NewDocGroup table. OldDocID is inserted as NewDocID and deptID is as-is. Instead of groupID, the ID of the first record in the
group should be considered as parentNewDocID (For example, 3 is considered as parentNewDocID for newDocID 5 as 3 and 5 belong to the same groupID in @OldDoc table) for the newDocID.
DECLARE @NewDocGroup (newDocID INT, parentNewDocID INT, deptID INT)
INSERT INTO @NewDocGroup (newDocID, parentNewDocID, deptID) VALUES (1,1,111),(2,2,111),(3,3,111),(4,4,333),(5,3,222),(6,6,333),(7,7,222),(8,7,333),(9,9,111),(10,10,222),(11,11,333),(12,10,444)
How do I accomplish the above using SQL ? Thanks for the help.

Rows are not records. Tables have to have a key by definition. You do not do math with identifiers, so they should not be numeric. Let's ignore that error for now. In short, you are posting garbage. If you had followed Forum Netiquette, would you have posted
this?
CREATE TABLE Old_Documents
(old_doc_id INTEGER NOT NULL PRIMARY KEY,
group_id INTEGER,
dept_nbr INTEGER NOT NULL
REFERENCES Departments (dept_nbr));
INSERT INTO Old_Documents(old_doc_id, group_id, dept_nbr)
VALUES (1, NULL, 111),
(2, NULL, 111),
(3, 1, 111),
(4, NULL, 333),
(5, 1, 222),
(6, NULL, 333),
(7, 2, 222),
(8, 2, 333),
(9, NULL, 111),
(10, 3, 222),
(11, NULL, 333),
(12, 3, 444);
>> I need to process the data from the above table (Old_Documents) and write into two new tables (New_Documents and New_Documents_Groups) as follows. <<
Just like punch cards and mag tape data processing! Being old and being new are a status, not another kind of entity. But that is how mag tapes work. And you even use the verb "fetch" from tape files. This design flaw is called attribute splitting.
Do you have a Male_Personnel and Female_Personnel table? NO! It is just Personnel!
>> old_doc_id should be stored as new_doc_id when inserting to New_Documents table. Only records [sic] with group_id NULL and one record [sic] (first [sic; no ordering in a table] one) per group should be considered (For example, old_doc_id 5 is not considered
as 3 and 5 belong to the same group_id =1) for insertion. <<
Think about your punch card mindset. Why did you physically materialize that redundant New_Documents table? Let me answer that: this is how you work with punch cards! In SQL we use a VIEW:
CREATE VIEW New_Documents (new_doc_id)
AS
SELECT old_doc_id
FROM Old_Documents;
>> All records [sic] from Old_Documents should be considered for insertion into New_Documents_Groups table. The old_doc_id is inserted as new_doc_id and dept_nbr is as-is. Instead of group_id, the ID [sic: which identifier??] of the first [sic: tables
have no ordering like a deck of punch cards] record [sic] in the group should be considered as parent_new_doc_id (For example, 3 is considered as parent_new_doc_id for new_doc_id 5 as 3 and 5 belong to the same group_id in Old_Documents table) for the new_doc_id.
<<
Why not use 5 as the parent? My guess is that you are trying to form equivalence classes. See:

Fetch data from two tables and insert into one table

I have similar to the following data in two tables (@Plant, @PlantDirector) and need to consolidate into one table (@PlantNew) as follows.
DECLARE @Plant TABLE (PlantID INT, PlantName VARCHAR(100))
INSERT INTO @Plant (PlantID, PlantName) VALUES (1, 'Name One'),(2, 'Name Two'),(3, 'Name Three'),(4, 'Name Four'),(5, 'Name Five'),(6, 'Name Six')
Director data for the Plants exist in the following table. Assistant value 1 means Assistant Director and 0 means Director.
Data exists only for subset of plants and a Plant may have one or both roles.
DECLARE @PlantDirector TABLE (PlantID INT, PlantDirectorID INT, Assistant bit)
INSERT INTO @PlantDirector (PlantID, PlantDirectorID, Assistant) VALUES (2, 111, 1),(2, 222, 0),(4, 333, 0),(6,444,1)
The above data needs to be inserted into one table (@PlantNew) as follows:
PlantID in @Plant table is IDENTITY value and needs to be inserted as-is into this table.
PlantDirExists will get a value of 1 if at least one record exists in @PlantDirector table for a PlantID. PlantAssistantDirID and PlantDirID should be set to the corresponding PlantDirID or NULL appropriately depending on the data.
DECLARE @PlantNew TABLE (PlantID INT, PlantName VARCHAR(100), PlantDirExists bit, PlantAssistantDirID INT, PlantDirID INT)
INSERT INTO @PlantNew (PlantID, PlantName, PlantDirExists, PlantAssistantDirID, PlantDirID)
VALUES (1, 'Name One', 0, NULL, NULL),(2, 'Name Two', 1, 111, 222),(3, 'Name Three', 0, NULL, NULL),(4, 'Name Four', 1, NULL, 333),(5, 'Name Five', 0, NULL, NULL),(6, 'Name Six',1, 444, NULL)
How do I achieve the above using SQL ? Thanks.

like this
INSERT @PlantNew (PlantID, PlantName, PlantDirExists, PlantAssistantDirID, PlantDirID)
SELECT p.PlantID,
p.PlantName,
CASE WHEN pd.PlantID IS NULL THEN 0 ELSE 1 END,
PlantAssistantDirID,
PlantDirID
FROM @Plant p
LEFT JOIN (SELECT PlantID,
MAX(CASE WHEN Assistant = 1 THEN PlantDirectorID END) AS PlantAssistantDirID,
MAX(CASE WHEN Assistant = 0 THEN PlantDirectorID END) AS PlantDirID
@PlantDirector
GROUP BY PlantID)pd
ON pd.PlantID = p.PlantID
Please Mark This As Answer if it helps to solve the issue Visakh ---------------------------- http://visakhm.blogspot.com/ https://www.facebook.com/VmBlogs
You're missing a FROM
insert into @PlantNew
SELECT p.PlantID,
p.PlantName,
CASE WHEN pd.PlantID IS NULL THEN 0 ELSE 1 END,
PlantAssistantDirID,
PlantDirID
FROM @Plant p
LEFT JOIN (SELECT PlantID,
MAX(CASE WHEN Assistant = 1 THEN PlantDirectorID END) AS PlantAssistantDirID,
MAX(CASE WHEN Assistant = 0 THEN PlantDirectorID END) AS PlantDirID
from @PlantDirector
GROUP BY PlantID)pd
ON pd.PlantID = p.PlantID
