Read/Insert values from comma separated string

I need Stored procedure to insert values in table using comma separated values from string based on algorithm as below.
There are two table Mtable(Parent table), Ctable(Child table).
Value passed from String can be like_
1,A001,R1,C1,R2,C2,R3,C3
2,A002,X1,Y1,X2,Y2
3,A003,A1,B1,A2,B2,A3,B3
1)For line1 I need to insert in Mtable values(1,A001)
And in ctable I need to insert 3 rows with values
     ROW1     (1,R1,C1)
     ROW2     (1,R2,C2)
     ROW3     (1,R3,C3)
2)For line2 I need to insert in Mtable values(2,A002)
And in ctable I need to insert 2 rows with values
     ROW1     (2,X1,Y1)
     ROW2     (2,X2,Y2)
Please help me to overcome this.
Thanks

Remove Duplicates From Comma Separated String

Hi,
I have one Column which contains duplicates values with comma separated.
Customer ID
5,5,5,5,6,6,5,5,5,6,7,4,1,2,1,4,7,2
I wrote this:
select REGEXP_REPLACE('5,5,5,5,6,6,5,5,5,6,7,4,1,2,1,4,7,2', '(^|,)([^,]*)(,\2)+','\1\2') from dual;
5,6,5,6,7,4,1,2,1,4,7,2
But it eliminates only continuous elements.
I want out put like:
5,6,7,4,1,2
Please help.
Thanks.

Reading any value from table into a string (Especially date etc..)

How would I read any value from a table into a string?
Currently doing the following...
data ret_val type string.
select single (wa_map-qes_field) from z_qekko into ret_val
where
angnr = _angnr.
When the source field is a date it bombs though.
The result goes into a BDCDATA-fval.
regards
Dylan.

Tried...
1    DATA: lp_data TYPE REF TO DATA.
2    FIELD-SYMBOLS: <value> TYPE ANY.
3    CREATE DATA lp_data LIKE (wa_map-qes_field).
4    ASSIGN lp_data->* TO <value>.
5    SELECT SINGLE (wa_map-qes_field) FROM zquadrem_qekko INTO <value> WHERE angnr = _angnr.
Complains that (wa_map-qes_field) is not defined in line 3.
Think that the bracket thing is only available via SQL.
What about CREATE DATA lp_data type ref to object. ?
Would the above declaration work?
regards

"but the sad thing is, that managers will most likely respond with a "This used to be fast in MSSQL, but now it isn't any more in Oracle. Oracle is so slow ...""
On the bright side, it sounds like most of the database calls are implemented as stored procedures, so there is an opportunity to do it right (in Oracle terms) in the stored procedures.
I did a similar conversion a while back, converting bad SQLServer procedures to good Oracle procedures. Everyone said "Oracle is much faster that SQLServer"

Convert comma separated string in rows

Dear Gurus,
I want to convert comma separated string in rows so as to insert in collection.
e.g. string 1234,2323,23232,2343,34234
Above string should be converted in rows so as to insert in table or collection
Thanks in advance
Sanjeev

Or slight variation...
SQL> ed
Wrote file afiedt.buf
1 with t as (select '1234,2323,23232,2343,34234' as txt from dual)
2 --
3 select REGEXP_SUBSTR (txt, '[^,]+', 1, level)
4 from t
5* connect by REGEXP_SUBSTR (txt, '[^,]+', 1, level) is not null
6 /
REGEXP_SUBSTR(TXT,'[^,]+',
1234
2323
23232
2343
34234... so it doesn't have to work out how many levels it needs to do, it just keeps going until it get's a no-value (of course that assumes that there is always a value between each comma)

MODEL clause to process a comma separated string

Hi,
I'm trying to parse a comma separated string using SQL so that it will return the parsed values as rows;
eg. 'ABC,DEF GHI,JKL' would return 3 rows;
'ABC'
'DEF GHI'
'JKL'
I'm thinking that I could possibily use the MODEL clause combined with REGULAR expressions to solve this as I've already got a bit of SQL which does the opposite ie. turning the rows into 1 comma separated string;
select id, substr( concat_string, 2 ) as string
from (select 1 id, 'ABC' string from dual union all select 1, 'DEF GHI' from dual union all select 1, 'JKL' from dual)
model
return updated rows
partition by ( id )
dimension by ( row_number() over (partition by id order by string) as position )
measures ( cast(string as varchar2(4000) ) as concat_string )
rules
upsert
iterate( 1000 )
until ( presentv(concat_string[iteration_number+2],1,0) = 0 )
( concat_string[0] = concat_string[0] || ',' || concat_string[iteration_number+1] )
order by id;
Can anyone give me some pointers how to parse the comma separated string using regexp and create as many rows as needed using the MODEL clause?

Yes, you could do it without using ITERATE, but FOR ... INCREMENT is pretty much same loop. Couple of improvements:
a) there is no need for CHAINE measure
b) there is no need for CASE in RULES clause
c) NVL can be applies on measures level
with t as (select 1 id, 'ABC,DEF GHI,JKL,DEF GHI,JKL,DEF GHI,JKL,DEF,GHI,JKL' string from dual
   union all
    select 2,'MNO' string from dual

Look Up For Comma Separated Strings

Hi,
How to look up for comma separated string from livecycle forms manager ??
Plz gimme an idea on this.
Raghava Kumar V.S.S.

Hi
My point is that the more detailed you ask your question, the more likely you are to get an answer.
Those of us who monitor these newsgroups also appreciate you doing as much of your own research as possible, before asking us for help - we're more likely to spend our own (personal and valuable) time helping you, if we know that you've spent your own time doing research, and you've still not been able to solve the problem.
I look forward to your next question :-)

How can I insert values from table object into a regular table

I have a table named "ITEM", an object "T_ITEM_OBJ", a table object "ITEM_TBL" and a stored procedure as below.
CREATE TABLE ITEM
ITEMID VARCHAR2(10) NOT NULL,
PRODUCTID VARCHAR2(10) NOT NULL,
LISTPRICE NUMBER(10,2),
UNITCOST NUMBER(10,2),
SUPPLIER INTEGER,
STATUS VARCHAR2(2),
ATTR1 VARCHAR2(80),
ATTR2 VARCHAR2(80),
ATTR3 VARCHAR2(80),
ATTR4 VARCHAR2(80),
ATTR5 VARCHAR2(80)
TYPE T_ITEM_OBJ AS OBJECT
ITEMID VARCHAR2(10),
PRODUCTID VARCHAR2(10),
LISTPRICE NUMBER(10,2),
UNITCOST NUMBER(10,2),
SUPPLIER INTEGER,
STATUS VARCHAR2(2),
ATTR1 VARCHAR2(80),
ATTR2 VARCHAR2(80),
ATTR3 VARCHAR2(80),
ATTR4 VARCHAR2(80),
ATTR5 VARCHAR2(80)
TYPE ITEM_TBL AS TABLE OF T_ITEM_OBJ;
PROCEDURE InsertItemByObj(p_item_tbl IN ITEM_TBL, p_Count OUT PLS_INTEGER);
When I pass values from my java code through JDBC to this store procedure, how can I insert values from the "p_item_tbl" table object into ITEM table?
In the stored procedure, I wrote the code as below but it doesn't work at all even I can see values if I use something like p_item_tbl(1).itemid. How can I fix the problem?
INSERT INTO ITEM
ITEMID,
PRODUCTID,
LISTPRICE,
UNITCOST,
STATUS,
SUPPLIER,
ATTR1
) SELECT ITEMID, PRODUCTID, LISTPRICE,
UNITCOST, STATUS, SUPPLIER, ATTR1
FROM TABLE( CAST(p_item_tbl AS ITEM_TBL) ) it
WHERE it.ITEMID != NULL;
COMMIT;
Also, how can I count the number of objects in the table object p_item_tbl? and how can I use whole-loop or for-loop to retrieve values from the table object?
Thanks.

Sigh. I answered this in your other How can I convert table object into table record format?.
Please do not open multiple threads. It just confuses people and makes the trreads hard to follow. Also, please remember we are not Oracle employees, we are all volunteers here. We answer questions if we can, when we can. There is no SLA so please be patient.

Problem reading RFC values from IRecordSet !!!!

Hi All,
I am having some problem reading values from IRecordSet. Can not seem to parse the output structure from RFC. AM using connector gateway service to execute BAPI_EXCHRATE_GETCURRENTRATES.
Here is the code,
MappedRecord input = rf.createMappedRecord("input");
input.put("DATE",new String("01011990"));
input.put("DATE_TYPE", new String("V"));
input.put("RATE_TYPE", new String("M"));
MappedRecord output = (MappedRecord) ix.execute(ixspec, input);
Object rs = null;
IRecordSet recSet = null;
Object result = output.get("EXCH_RATE_LIST");
if (result == null) {
response.write("<BR>null");
rs = new String(" ");
} else if (result instanceof IRecordSet) {
IRecordSet irs = (IRecordSet) result;
response.write("<BR>Got some dataaa");
IRecordMetaData rsmd = null;
rsmd = irs.retrieveMetaData();
irs.beforeFirst();
while(irs.next()){
response.write("Row::"+irs.getString("RATE_TYPE")+" "+irs.getString("FROM_CURR")+" "+irs.getString("EXCH_RATE"));
Am getting the pritn statement, Got Some Data on the PDK component.
But somehow not able to read the values from IRecordSet
What is the mistake here?
Pls help
Edited by: Aakash Jain on Oct 11, 2008 12:22 AM

Hi
Try in this way.
IRecordSet resultTable = (IRecordSet)outputParams.get("TABLE_NAME");
for(resultTable.beforeFirst(); resultTable.next(); ) {
response.write(resultTable.getString(0));
response.write(resultTable.getString(1));

Passing comma separated string to stored procedure

Hi,
There is thread with same query I created earlier and that was answered. That solution worked if I pass comma separated string containing IDs. But due to changes in the logic, I have to pass usernames instead of userIDs. I tried to modify the solution provided to use with this.
Following the link to previous post :
Re: Passing comma separated string to stored procedure

Open TestPubs for

Hi,
I modified the query as per the solution provided by isotope, after which the logic changed and I am passing username instead of userID in comma separated string.
Following is the changes SP, which does not throw any error, but no data is returned.

One column having multiple values with comma separator.

Hey Guys,
In my db, one culmn having multiple values with comma separator. like column_name = 'value1,value2,value3'. Now I want to compare this column to another column and fetch in Cursor.
and each value having corresponding email_id, By fetching cursor, I need to populate email_ids.
Thanks in advance!!
-Lakshman

Please compare and fetch cursor and populate result with out extract data into temp table. Give me the query!You have not provided DDL for table so I don't know table or column name to write any SQL.
You have not provided DML for test data to run SQL against.

Subprocess 33 was not successful. Master cannot read return value from S 33

Hi All,
We are on BI 7.0 SP 19.
We have submitted a planning sequence in the background with automatic packaging.
The planning sequence has two steps:
Step 1. Z_PLNG_FUNCTION1
Step 2. Z_PLNG_FUNCTION2
As per automatic packaging, the system chose 0ACCOUNT for packaging.
When submitted, each step has been submitted to 30 packages as 30 subprocesses.
For Step 1, the log shows that All subprocesses executed.
For Step 2, the log shows that the subprocess 33 and 58 failed, which means subprocess #3, and # 28 for the step 2 as the subprocess is numbered in the log in combination with step 1.
The messages in the log for the failed subprocesses are as follows:

@5C\QError@     Master cannot read return value from subprocess 58
Our question is on how to find the exact cause of the subprocess failure.
I tried to look for the details on the error messages, they have been not helpful.
What is meant by 'Master cannot read return value from subprocess' and how to get the exact cause of the failure?
Thanks in advance,

Reading each value from spreadsheet file with delay (multiple rows and columns)

Hi,
a) I want to read EACH VALUE from a spreadsheet file having multiple rows and columns WITH DELAY. I am attaching my VI and sample datalog file for reference (tempsensor.txt).I need to do so because as soon as I read put ON the Sensor button on front panel, LV reads all the values at one go. I need the values for each temperature to be displayed after a delay.
b) Secondly, I would like to read another file containing the state of four antennas (deployed:1; undeployed:0). I am logging state of each antenna in each column of the file(magnet.txt) I need to have four LEDS on front panel to display state of the antennas. I dont know what I have done for antennas in my VI is right or wrong. I guess thats rhe wrong way to approach the problem. Please help!!!(column1: Antenna1 state ; Column2:Antenna2 state.. and so..on..)
Any help would be greatly appreciated!!
Thanks in advance,
Ratnesh
FYI: The first column in my datalog file represents timestamp(number of seconds elapsed), second column: reading for temperature sensor 1, third column: reading for temperature senosr 2, and so on. I am using approx. 11 temperature sensors.
Also, I have generated the log files for the reference purpose only. They do not represent the actual values. They are far away from actual values.

Look at this modified version of your VI. After looking at it, I determined that a shift reggister was not required in this case.
