Checking for existence of a record in csv file

Hey all, I have two csv files residing on the server that I will be processing using the UTL_FILE package. One of these files (File A) has only one column and the other one (File B) has over ten. The data in file A is the same as the one in column 2 of File B. File A is mainly there for a lookup purpose whereas File B is the one that has all the data that will be processed. The following example should describe better:
File A[b]
Number
"TR_56575"
"TY_76756"
etc
File B
Column1, Number, Column3, Column4
"Mine","TR_56575","uhsht","76744"
"Yours","TY_76756","nghdjd","45645"
What I have to do is check whether a Number in File B exists anywhere in File A. If it does then I just skip that record and move on to the next. So basically, I wanted to find out if there is any way to compare the two columns on the server side. I know there is a dbms_lob.fileexists function to check the existence of a file on a server, just wanted to see if there is an extension to that or something that checks the existence of a string in file. Any feedback would be appreciated. Thanks.

Yeah I thought about that. It would be the ideal way to go, however in this case, I already have a Pl/Sql procedure that grabs File B and just processes it from the server. It works fine and everything but now that this extra logic and file is added where I have to check the existence of a corresponding record in File A, I'm just looking for something to add in my code to just make the comparison on the fly and the rest would be the same.

Check for existence of a record

I have a table XX_TEMP. Let us say the columns are inventory_item, organization_id and description
The values are:
Inventory_item
Organization
Description
200
m1
Sample
200
m2
Not Sample
400
m4
check
700
m5
Test
I just want to check the existence of an item in the table, I have written two queries and would like to know which one is better in terms of performance:
Q1:
select count(1) from xx_temp where inventory_item=200 and rownum=1;
Q2:
select count(1) from dual where exists (select 1 from xx_temp where inventory_item=200);
Both Q1 and Q2 return the same result. In fact, I was surprised with the result from Q1 as I expected that the rownum would be evaluated after the where condition. I expected Q1 to return 2
I thought that the below query:
select count(1) from xx_temp where inventory_item=200;
and Q1 would return the same result as rownum would be evaluated at end. In effect, I've 2 questions:
1. Isn't rownum calculated at the end?
2. What is the best way in terms of performance to check for an existence of record?

Internally this is how it works:
select count(*) from xx_temp where inventory_item=200 and rownum=1;
COUNT(*)
         1
1 row selected.

Plan
1 Every row in the table XX_TEMP is read.
2 Processing was stopped when the specified number of rows from step 1 were processed.
3 The rows were sorted to support a group operation (MAX,MIN,AVERAGE, SUM, etc).
4 Rows were returned by the SELECT statement.
COUNT STOPKEY knows how many rows you want and will just keep calling its child function under it in the execution plan tree to get more and more rows, until the required amount of rows have been returned. Here it stopped at 1 iteration.
And to answer your second question : as to which is the fastest way to to check for an existence of record :
Answer would be it depends on your requirement. possible answers are : Rowid -- fastest way to check for a row.   similar answers can be Index etc.. but all this is relative to what you work with.

FM FOR CREATING NEW CONDITION RECORDS FROM INPUT FILE

Hello vikas,
I need to develop a interface program FOR CREATING NEW CONDITION RECORDS FROM INPUT FILE.
Is there ay function module to update or create the condtion records,
if u have any example interface program to update conditions records please send me.
regards
ram.

This must be your compiler output.
Basically, it is telling you two things that are wrong - in syntax.
1. On line number 11 of the file RationalCollection1.java, the compiler expects a type identifier - that would be the object or return type such as int, String, boolean, etc.
The reason it is doing this is probably due to your not ending a previous statement - like the "expected ';'" error statement. Check your code, make sure that methods (brackets) are closed correctly and there are no open statements (i.e. missing the semi-colen at the end).
2. On line number 33 of the file RationalCollection1.java, the compiler expected the closing bracket. Thus, you didn't put the bracket where the compiler wants it.
It appears that you have skipped some lines of code. Those lines are the problem, post them - post lines 30-36 and 9-15 so we can see what is happening around those error lines.

How to create a datasource for 0COSTCENTER to load data in csv file in BI

how to create a datasource for 0COSTCENTER to load data in csv file in BI 7.0 system
can you emil me the picture of the step about how to loaded individual values of the hierarchy using CSV file
thank you very much
my emil is <Removed>
allen

Step 1: Load Required Master Data for 0CostCenter in to BI system
Step 2: Enable Characteristics to support Hierarchy for this 0Cost Center and specify the External Characteristic(In the Lowest Node or Last Node) while creation of this Characteristic InfoObject
Step 3: On Last Node of Hierarchy Structure in the InfoObject, Right Click and then Create Hierarchy MANUALLY by Inserting the Master Data Value as BI dosent Support the Hierarchy load directly you need to do it manually....
Step 4: Mapping
Create Text Node thats the first node (Root Node)
Insert Characteristic Nodes
Insert the Last Node of the Hierarchy
Then you need to create a Open hub Destination for extracting data into the .csv file...
Step1 : Create the Open Hub Destination give the Master Data table name and enter all the fields required....and create the transformations for this Open Hub connecting to the External file or excel file source...then give the location on to your local disk or path of the server in the first tab and request for the data...It should work alright let me know if you need anything else...
Thanks,
Sandhya

Count total no of records in csv file

hello
i made a function which count total no of records in csv file.
but it always return 0 goes in the exception when no data found which
it also display the total no of records in another parameter.
code is here
CREATE OR REPLACE FUNCTION COUNT_RECORDS_CSV (storeid1 number ) RETURN NUMBER
IS
wfile_handl UTL_FILE.FILE_TYPE;
v_file varchar(100);
S VARCHAR2(32767);
c number :=0;

DBMS_OUTPUT.PUT_LINE('V_FILE='||v_file);
wfile_handl := UTL_FILE.FOPEN(v_dir,'DATA_5138.CSV','R');
LOOP
UTL_FILE.GET_LINE(wfile_handl,S);
C := C + 1;
END LOOP;
UTL_FILE.FCLOSE(wfile_handl);
RETURN C;
EXCEPTION
WHEN NO_DATA_FOUND THEN
RETURN 0;
END COUNT_RECORDS_CSV;
if i print the values of c it show me correct result but it always return 0 can any body told me why its happening.
thanks

The fact that you have written this:
EXCEPTION
WHEN NO_DATA_FOUND THEN
RETURN 0;means you didn't bother to read this.

Check for existence of a node?

What is the best way to check for the existence of a node (before attempting to delete it or perform other operation on it)? Maybe assign it an "id" then search for that id?

If the node is in a Container you can use lookup(id: String): Node function.

File adapter SyncRead Operation adds "???" to first record of csv file

One interface is reading one CSV file (containing two fields only) using SyncRead Operation of File Adapter. But I found, when file adapter parsed the data it appends "???" to first field of the first record which cause further data validation in the process.

Unfortunately, this is documented bahaviour (solution/workaround anyone?!):
Elapsed Time Exceeds:
Specify a time which, when exceeded, causes a new outgoing file to be created.
Note:
The Elapsed Time Exceeds batching criteria is evaluated and a new outgoing file is created, only when an invocation happens.
For example, if you specify that elapsed time exceeds 15 seconds, then the first message that is received is not written out, even after 15 seconds, as batching conditions are not valid. If a second message is received, then batching conditions become valid for the first one, and an output file is created when the elapsed time exceeds 15 seconds.

Duplicate record in CSV file

Hi
Needed your inputs to take forward this scenario
It is an IDOC - CSV File scenario where WBS elements are sent across in the file to the legacy system
9 fields are sent in the file and in those 2 fields are mapped with constants .
Requirement here is to have a duplication of record in the file with only one constant changed My CSV file should look like this for each IDOC occurence
AAA,0123.45,Edgbaston,1234,WBS_Code1,,Airline,
AAA,0123.45,Edgbaston,1234,WBS_Code2,,Airline,
it would just be the duplication of record with only one field changed (WBS_Code1 and WBS_code2) so that each IDOC occurence would comprise one WBSelement information sent from the IDOC and the generated file would have 2 lines of the same record
Thanks
Anusha

Hi
Unable to get you and I have my receiver strcuture as mentioned below .And only last 2fields are getting populated from the IDOC and rest all mapped with the constants

Loading records from .csv file to SAP table via SAP Program

Hi,
I have a .csv file with 132,869 records and I am trying to load it to an SAP table with a customized SAP program.
After executing the program, only 99,999 records are being loaded into the table.
Is there some setting to define how many records can be loaded into a table? Or what else could be the problem?
Pls advice.
Thanks!!!

hi Arun ,
A datasource need a extract structure to fetch data .It is nothing but a temp table to hold data.
First you need to create atable in SE11 with fields coming from CSV file.
Then you need to write a report program to read you CSV file and populate your table in BW .
Then you can create a datasource on top of this table .
After that replicate and load data at PSA and use to upper flow.

How to Query remote PC's registry by OU for 2 values and export to CSV file.

I'm new to scripting and to Powershell but this is what I have managed to put together so far. Of course it fails. We have two custom entries in the registry that I want to query remote workstations for these values, Monitor 1 and Monitor 2. Output to a
CSV along with the workstations name. Because of our AD structure I figured its just easier to input the OU individually as seen in the script. That portion of the script seems to work. I get the following error in bold when I run the script: I've Google'd
and tinkered with this for a week now with no resolution and seem to be going in circles. And yes, I had help to get this far.

Inserting Record into CSV file from BizTalk Orchestration

Scenario:
1.Receive file from Source system via RecvPipeline
2.In Orchestration extracting some values like ENO,Ename,Salary etc.these values to be added in to CSV file from Expression Shape.How to append/add emp records in to CSV with out overriding the rows.
Ex:If we submitted 10 files then the CSV file should contain 10 rows in CSV.
Let me know how to create CSV file from Orchestration and how to add rows into that csv value
Regards BizTalkWorship

Simple.
Receive the message through a Receive Port/Location.
Create a flat-file schema representing the CSV file structure. Ensure each row is delimited by “{CR}{LF}”.
This flat-file schema should only contain the element which you want to see in the destination CSV file like ENO,Ename,Salary etc.
Have a map where the source schema should be the one which represents the received file and destination schema should be the one which is above created flat-file schema.
Map the source schema to the destination schema mapping the filed
ENO,Ename,Salary etc.
Have a custom send pipeline with flat-file assembler component it. Use this send pipeline in the send port.
In send port, configure the send filter like “BTS.ReceivePortName == YourReceivePortName”. Configure the send port’s “Outbound Maps” to the map which you have created in
above step
Key Point. In your send port, set the “Copy Mode” property to “Append” from default “Create New”
With your send port’s, “Copy Mode” property configured to “Append” this will append the value of the output to the existing file. Since in your flat-file schema, each record
is delimited by “{CR}{LF}” and since you’re overwriting the output file you will have one file with records appended. So if 10 files received, instead of 10 output files, you will have 1 CVS file with 10 rows.
If you want to construct the message in Orchestration as do, you do as opposed to map in send port at outbound map you can still do.

Restrict records in CSV file based on condition

Greetings. I searched the forum for my issue and didn't find an answer or the right search terms. I am running APEX 4.1.1
I have a report on a page. I am showing all records for a given SQL statement in my table, but in the "Export to CSV" I need to limit the output based on one of the fields. So for example, if I had a report like:
SELECT x, y, Z
FROM Table1
I would like the Export to CSV for that table to limit the output such as:
SELECT x, y, Z
FROM Table1
WHERE Z = 1
Is that possible?
Thanks!
John

Hi John,
I have tested the login now and the above works for Interactive report only and for Classic report you need to do something like this because the request is set to different value
SELECT x, y, Z
FROM Table1
WHERE ((Z = 1 and nvl(:REQUEST,'X') like 'FLOW_EXCEL_OUTPUT%') OR nvl(:REQUEST,'X') not like 'FLOW_EXCEL_OUTPUT%')See this working example http://apex.oracle.com/pls/apex/f?p=46417:25
When you export to csv you will only get dept 10 records
