Comparision Merge clause vs If not exists

Hi Team,
There exits various stored procedures, wherein developer has used if exists then update and if not then inserted records.
I would like to know, what is good option, considering with the fact that, stored procedure must be optimized and need to consume less resources.
Thanks

Not able to migrate a query with not exist clause

Hi all,
I'm using Toplink 10.1.3 and I am trying to rewrite the following query with Expression Framework:
select distinct r.e_ogg_oper_k_oggetto
FROM regola_accettazione_oper_banc r, oggetto_operazione_bancaria o
where not exists (
select 1
FROM limitaz_ogg_tipo_oper_banc l
where nvl(l.d_fine_validita,trunc(sysdate)+1)>trunc(sysdate)
and l.d_inizio_validita <= trunc(sysdate)
and l.e_tpodv_k_tipo_operazione=:appoggio.tipo_operaz
and l.e_ogg_oper_k_oggetto=r.e_ogg_oper_k_oggetto
and l.e_uni_oper_k_unita_oper_util= :appoggio.e_uni_oper_k_unita_oper_esegui )
and r.e_oper_ban_k_operaz_bancaria=:appoggio.form
and r.e_ogg_oper_k_oggetto=o.k_oggetto
and o.e_ogg_oper_k_oggetto is null
and o.k_oggetto != nvl(:appoggio.oggetto_autom,,'0')
and o.k_oggetto like substr(:appoggio.oggetto,1,2)||'%'
and r.d_inizio_validita <= :appoggio.d_contab
and to_date(nvl(to_char(r.d_fine_validita,DD/MM/YYYY'),31/12/3999'),'DD/MM/YYYY')> :appoggio.d_contab
and o.f_natura_oggetto in ('G','P') and r.f_oggetto_automatizzato!='S'
I'm not able to "attach" the not exist clause to the rest of query.
How can I do it?
Thank you very much.

Not exists can be used in an expression through using a ReportQuery sub-query.
i.e.
ExpressionBuilder outerBuilder = new ExpressionBuilder();
ReadAllQuery outerQuery = new ReadAllQuery(Employee.class, outerBuilder);
ExpressionBuilder subBuilder = new ExpressionBuilder();
ReportQuery subQuery = new ReportQuery(Address.class, subBuilder);
subQuery.addAttribute("id");
subQuery.setSelectionCriteria(
subBuilder.get("city").equal(outerBuilder.get("address").get("city")
.and(subBuilder.notEqual(outerBuilder.get("address")))));
outerQuery.setSelectionCriteria(
outerBuilder.notExists(subQuery));
List results = (List) session.executeQuery(outerQuery);
Refer to the documentation section on sub-queries for more information.
I would suggest simlpifying the where clause until you get the sub-query working to start.
You can also always use a custom SQL query in TopLink.

What version of Oracle are you using? This message does not appear in my 10.1 Error Messages document, but the other messages in that range seem to be about DBMS_SCHEDULER.
Are you using scheduler somewhere around where you are getting the error message?

Using SSIS 2012 - merge join component to transfer data to destination provided it does not exist

HI Folks,
I have a table - parts_amer and this table exists in source & destination server as well.
CREATE TABLE [dbo].[Parts_AMER](
[ServiceTag] [varchar](30) NOT NULL,
[ComponentID] [decimal](18, 0) NOT NULL,
[PartNumber] [varchar](20) NULL,
[Description] [varchar](400) NULL,
[Qty] [decimal](8, 0) NOT NULL,
[SrcCommodityCod] [varchar](40) NULL,
[PartShortDesc] [varchar](100) NULL,
[SKU] [varchar](30) NULL,
[SourceInsertUpdateDate] [datetime2](7) NOT NULL,
CONSTRAINT [PK_Parts_AMER] PRIMARY KEY CLUSTERED
[ServiceTag] ASC,
[ComponentID] ASC
I need to exec the following query using SSIS components so that only that data ,is transfered,which does not exist at destination -
select source.*
from parts_amer source left join parts_amer destination
on source.ServiceTag = destination.ServiceTag
and source.ComponentID=destination.ComponentID
where destination.ServiceTag is null and destination.ComponentID is null
Question - Can Merge component help with this?
Pl help out.
Thanks.

Hi Rvn_venky2605,
The Merge Join Transformation is used to join two sorted datasets using a FULL, LEFT, or INNER join, hence, not suitable in your scenario. As James mentioned, you can use Lookup Transformation to redirect the not matched records to the destination table.
Another option is to write a T-SQL script that makes use of
Merge statement, and execute the script via Execute SQL Task.

Wrong query is getting generated in WHERE NOT EXISTS with group by clause

Query is getting generated wrongly in where not exists section when i use group by function.Please prvoide me any clue to over come the problem.

     FROM     EDW.DCMT_TIMEZONE_LOOKUP T
     WHERE     T.TZ_OFFSET     = S.TZ_OFFSET AND
     )

Easiest fix for you would be to change the detection_strategy on the IKM from NOT_EXISTS to either :
MINUS
-- Try this out, it should work, it will give the same data through the equiverlant steps.
NONE
-- This will load all incoming data into your I$ table, there will be more rows to crunch in the following 'Flag Rows for Update' step, it might give incorrect results potentially - you will have to test it.
So try MINUS first, failing that, see if NONE gives you what you want in your target.
Are you inserting only new data or updating existing data?

Insert when not exists

Is there anyway of getting owb to implement the following sql without
resorting to using a insert update operation:
insert into desttable
(select * from myview where not exists (select null from b where desttable.emp_id=myview.emp_id)
This sounds almost like the perfect application for an insert/update (or merge)
operation. But in my case, I do not want to update the destination tables if I get
a match, I am only interested in using the insert part of a merge operation. I could
create a dummy update clause, but that would be a waste of resources.
Any ideas?
Graeme

What I've done in this situation, and there might be a better way, is use an outer join. Essentially, I do this:
insert into desttable (
select a.*
from mytable a, desttable b
where a.emp_id = b.emp_id(+)
and b.emp_id is null
I believe this accomplishes the same thing as "not exists".

INSERT rows that do not exist

I need to update (post) a table with summarized totals from another table. It is possible that the matching rows do not exist so I want to insert them before posting (UPDATE) to them. There is a table named BillingDetail that is summarized to insert into
another table named BillingHistory when rows do not match on 4 different columns. Below is my first shot at doing this but am not sure if the NOT IN clause is correct or maybe there is another (better) way.
INSERT INTO [dbo].[BillingHistory]
([entity]
,[plincd]
,[pgrpcd]
,[pitmcd]
,[hstyr]
,[corpnbr]
SELECT @entity
,plincd
,pgrpcd
,pitmcd
,@hstyr
,corpnbr
FROM (SELECT plincd
,pgrpcd
,pitmcd
,corpnbr
,SUM(qty) AS TotalQty
,SUM(extprc) AS TotalExtPrice
FROM dbo.BillingDetail
GROUP BY corpnbr, plincd, pgrpcd, pitmcd) AS DT
WHERE pitmcd NOT IN(SELECT pitmcd FROM dbo.BillingHistory WHERE plincd = DT.plincd AND pgrpcd = DT.pgrpcd AND pitmcd = DT.pitmcd AND corpnbr = DT.corpnbr);

Not knowing the keys of BillingHistory, it is difficult to say whether your INSERT is correct, but it does look funny. My guess is that all six columns constitute the key, in which case this would be better:
   INSERT INTO [dbo].[BillingHistory]
   ([entity]
   ,[plincd]
   ,[pgrpcd]
   ,[pitmcd]
   ,[hstyr]
   ,[corpnbr]
SELECT @entity
   ,plincd
   ,pgrpcd
   ,pitmcd
   ,@hstyr
   ,corpnbr
FROM (SELECT plincd
,pgrpcd
,pitmcd
,corpnbr
,SUM(qty) AS TotalQty
,SUM(extprc) AS TotalExtPrice
   FROM dbo.BillingDetail
   GROUP BY corpnbr, plincd, pgrpcd, pitmcd) AS DT
WHERE NOT EXISTS (SELECT *
   FROM   dbo.BillingHistory BH
   WHERE BH.entity = @entity
   AND BH.plincd = DT.plincd
   AND BH.pgrpcd = DT.prgpcd
   AND BH.pitcmd = DT.pitcmd
   AND BH.hstyr = @hstyr
   AND BH.corpnbr = DT.corpnbr)
And even better may be to use MERGE as Ronen suggested, but I want to see the CREATE TABLE statements (including keys) for the table before I try that.

If image file not exist in image path crystal report not open and give me exception error problem

Hi guys my code below show pictures for all employees
code is working but i have proplem
if image not exist in path
crystal report not open and give me exception error image file not exist in path
although the employee no found in database but if image not exist in path when loop crystal report will not open
how to ignore image files not exist in path and open report this is actually what i need
my code below as following
DataTable dt = new DataTable();
string connString = "data source=192.168.1.105; initial catalog=hrdata;uid=sa; password=1234";
using (SqlConnection con = new SqlConnection(connString))
con.Open();

da.SelectCommand = cmd;
da.Fill(dt);
foreach (DataRow dr in dt.Rows)
FileStream fs = null;
fs = new FileStream("\\\\192.168.1.105\\Personal Pictures\\" + dr[0] + ".jpg", FileMode.Open);

byte[] imgbyte = new byte[fs.Length + 1];
imgbyte = br.ReadBytes(Convert.ToInt32((fs.Length)));
dr["Image"] = imgbyte;
fs.Dispose();
ReportDocument objRpt = new Reports.CrystalReportData2();
objRpt.SetDataSource(dt);
crystalReportViewer1.ReportSource = objRpt;
crystalReportViewer1.Refresh();
and exception error as below

First: I created a New Column ("Image") in a datatable of the dataset and change the DataType to System.Byte()
Second : Drag And drop this image Filed Where I want.

Short dump 'Table does not exist in database'

Hello All,
When a report is executing it is going to short dump by saying 'Table does not exist in database'. As per the short dump analysis this issue is happening because of the following   Native SQL statement statement :
Program : %_T050N0 (This is a dynamic program generating by SAP )
Form Name : DYN_LIC_SEL_TOT
exec sql performing LOOP_MOVE_WRITE_ISAP.
select single_plate, itm_num, ctry_code, model_lot,
lic_hold_flg, qty into :dcat-lplate, :dcat-matnr,
:dcat-werks, :dcat-charg, :dcat-holdflag,
:dcat-qty from ZLICENSE_R2 where itm_num   = :p_matnr and
                model_lot = :p_charg
endexec.
As per the customer this issue occurring since they migrated the SAP back-end data base from Oralce to DB6. Here I felt that ZLICENSE_R2 is not migrated from the Oracle to DB6. But as per the BASIS Team, even this table was not maintained in Oracle also. If the table was not maintained in the Oracle, this issue should have been there even before migration also.
Following is the short dump details:
Short text
    Table does not exist in database.
What happened?
    The table or view name used does not
    exist in the database.
    The error occurred in the current database connection "DEFAULT".
What can you do?
    Check the spelling of the table names in your report.
    Note down which actions and inputs caused the error.
    To process the problem further, contact you SAP system
    administrator.
    Using Transaction ST22 for ABAP Dump Analysis, you can look
    at and manage termination messages, and you can also
    keep them for a long time.
Error analysis
    An exception occurred that is explained in detail below.
    The exception, which is assigned to class 'CX_SY_NATIVE_SQL_ERROR', was not
     caught in
   procedure "DYN_LIC_SEL_TOT" "(FORM)", nor was it propagated by a RAISING
clause.
Since the caller of the procedure could not have anticipated that the
exception would occur, the current program is terminated.
The reason for the exception is:
Triggering SQL statement: "select single_plate, itm_num, ctry_code, model_lot,
lic_hold_flg, qty from ZLICENSE_R2 where itm_num = ? and model_lot = ? "
Database error code: "-204"
Could you please let me know what might be the reason for this issue.
Many Thanks in Advance.

Transaction SE11, input ZLICENSE_R2 for table name, and display the table. Did the table display? If not, that is the main problem.
If the table displays, go to menu item Utilities -> Database Object -> Database Utility
In the resulting screen, under the "Status" fields, you should see text "Exists in the database." If you don't, then the table exists in the dictionary, but doesn't exist in the database system. Click the "Create database table" button and then you should be able to run the program.
You may need basis team's help to carryout some of these actions.

Actually NOT IN and NOT EXISTS both used index for the second inner table (SM_APPL.SM_VDA_ALLOCATION_DETAIL).
But NOT exists is not using the index for the first table but not in is using.
how come.

I have an "old" Apple ID set up 13 years ago. Apple has now gone to using email address as the apple ID. I have apps to update and they ask for old ID. it does not exist. How can I get the ID on the app changed to the new apple ID

I set up an apple id many years ago when itunes was established. Within the past year or so, Apple has changed to using email address as user id. My problem is that I have many applications that I can not update due to the fact that it is asking for the password of the old ID. It does not exist anymore. Any ideas on how to get the new apple id associated with the application without deleting the application. Several of these apps I purchased.

You can not merge accounts.
Apps are tied to the Apple ID used to download them, you can not transfer them.

Primary index does not exist in database but shows in SE14?

I added a couple of key fields to a Z table and activated it. Every thing went well - adjusted it with SE14 also.
When I checked the Runtime object - it is OK.
When I checked Database Object, it is showing that the Primary Index does not exist in Database but SE14 says that the Priamry Index exists in Database.
Please advise how to correct this. I saw another psoting when I searched per this error message: "Indexes: Inconsistent with DDIC source" . It tells to create this index at Database but need to know the steps.
pl advise.

hi,
To create a index for a table,
go to se11->click on Indexes tab and create a primary index.
Indexes speed up data selection from the database. They consist of selected fields of a table, of which a copy is then made in sorted order. If you specify the index fields correctly in a condition in the WHERE or HAVING clause, the system only searches part of the index (index range scan).
The system automatically creates the primary index. It consists of the primary key fields of the database table. This means that for each combination of fields in the index, there is a maximum of one line in the table. This kind of index is also known as UNIQUE.
If you cannot use the primary index to determine the result set because, for example, none of the primary index fields occur in the WHERE or HAVINGclauses, the system searches through the entire table (full table scan). For this case, you can create secondary indexes, which can restrict the number of table entries searched to form the result set.
You create secondary indexes using the ABAP Dictionary. There you can create its columns and define it as UNIQUE.
reward points if useful.

The contained field name "ADTAGR" does not exist in any of the database tab

hı all
how can l solved thıs problem
An exception occurred that is explained in detail below.
The exception, which is assigned to class 'CX_SY_DYNAMIC_OSQL_SEMANTICS', was
not caught in
procedure "PUT_QMFECAT" "(FORM)", nor was it propagated by a RAISING clause.
Since the caller of the procedure could not have anticipated that the
exception would occur, the current program is terminated.
The reason for the exception is:
An Open SQL clause was specified dynamically. The contained field name
"ADTAGR" does not exist in any of the database tables from the FROM clause.
Information on where terminated
    Termination occurred in the ABAP program "SAPDBZQNQ" - in "PUT_QMFECAT".

    The termination is caused because exception "CX_SY_DYNAMIC_OSQL_SEMANTICS"

     declared
    in the RAISING clause of its signature.

You seem to have made a copy of the standard program. You'll have to make sure that you are handling this field correctly in your code.

Error analysis
An exception occurred that is explained in detail below.
The exception, which is assigned to class 'CX_SY_IMPORT_MISMATCH_ERROR', was
not caught in
procedure "MCEX_BW_LO_API" "(FUNCTION)", nor was it propagated by a RAISING
clause.
Since the caller of the procedure could not have anticipated that the
exception would occur, the current program is terminated.
The reason for the exception is:
When importing object "MC13VD0KON_TAB", the structure did not match the
structure of the target object. The error occurred in component
no. 21.
This may be due to one of the following reasons:
- the structure is actually different (the next field has, for
example, a different data type) or
- the same sequence of components were exported and imported,
but the fields were from other include units.
How to correct the error
There is a probably a new version of the program active that does
not match the dataset. The data may not have been converted.
It is also possible that the field type of the imported field
has been changed in the Data Dictionary.
Try to eliminate the error by regenerating the program "SAPLMCEX". To
do this, proceed as follows:
Call Transaction SE38 in the R/3 System, enter the program
name "SAPLMCEX" and then choose "Generate".
If the error occurred in your own ABAP program or in an SAP
program you modified, try to remove the error.
If the error occures in a non-modified SAP program, you may be able to
find an interim solution in an SAP Note.
If you have access to SAP Notes, carry out a search with the following
keywords:
"IMPORT_ALIGNMENT_MISMATCH" "CX_SY_IMPORT_MISMATCH_ERROR"
"SAPLMCEX" or "LMCEXU06"
"MCEX_BW_LO_API"
If you cannot solve the problem yourself and want to send an error
please help me in this regards
Quick response will be appreciated.
Thanks in advance
