Parsing nested delimited text to multiple tables

I am attempting to load data from a flat text file into multiple tables, with a 1:N relationship. If possible, I would like to have a control file that is able to update both tables simultaneously and populate the foreign key correctly.
Here is how the data that I am trying to parse is formatted:
Field1<TAB>Field2<TAB>RelatedField1/RelatedField2/RelatedField3, RelatedField1/RelatedField2/RelatedField3, RelatedField1/RelatedField2/RelatedField3<CRLF>
As you can see, there are 3 nested delimitation levels. I would like the first two fields (separated by tabs) to go into the first table, followed by a foreign key that references the second table, which is populated from the data following the second tab. The comma delimiters in the data following the second tab separate individual records to be put into the second table, and the slashes delimit the fields in that table.
Here is what the two tables should look like:
Table1
Table1_PK (Generated automatically by sequence)
Field1
Field2
Table2
Table2_PK (Generated automatically by sequence)
Table1_FK (Matches Table1_PK)
RelatedField1
RelatedField2
RelatedField3
Any suggestions on this would be appreciated. Thank you!

Another problem is that the number of "records" listed after the second tab varies. For eample:
Field1<TAB>Field2<TAB>RelatedField1/RelatedField2/RelatedField3<CRLF>
Field1<TAB>Field2<TAB>RelatedField1/RelatedField2/RelatedField3, RelatedField1/RelatedField2/RelatedField3<CRLF>
Field1<TAB>Field2<TAB>RelatedField1/RelatedField2/RelatedField3, RelatedField1/RelatedField2/RelatedField3, RelatedField1/RelatedField2/RelatedField3<CRLF>

HELP! How to insert long delimited text into a table

Friends,
I have an Oracle table with a long field containing comma delimited text.
Table Def:
QUOTE_LINES
(quote_no VARCHAR2(20),
quote_data LONG)
Example data from quote_data field:
A='750 Gallon',B='1250',C='300HP',D='Transmission',E=TRUE,F='Top Mount',G='Full Height',H='Full Height'
Note: There are no <CR> in the data.
I want to create a trigger on the table that loads the data into a separate table like this:
quote_no VARCHAR2(20),
line_type VARCHAR2(50),
line_value VARCHAR2(30)
Any suggestions?
Larry

Hello
Really, if at all possible you should look at converting the long column to a clob. This will get rid of lots of limitations and you will be able to treat the column just like a varchar2.
Anyway, if you cannot change from a long for the mean time, you could use the following, as long as the length of the text in your long column doesn't exceed 32k (which by all accounts is pretty large!):
SQL> create table dt_test_long (id number, big_text long);
Table created.
SQL> create or replace procedure dt_test_proc(an_id in dt_test_long.id%type)
2 IS
3
4     lv_LongVal      VARCHAR2(32767);
5
6 BEGIN
7
8     SELECT
9             big_text
10     INTO
11             lv_LongVal
12     FROM
13             dt_test_long
14     WHERE
15             id = an_id;
16
17     dbms_output.put_line(lv_LongVal);
18
19     --do whatever you want with the value here
20
21 END;
22 /
Procedure created.

Best way to implement oracle TEXT on multiple tables with regular updates

Hi,
I have the following situation:
5 tables where we want full text search on multiple columns.
Some of the tables have a master/detail relation. (1 to 1000, or more)
because of the number of transactions on these tables we can't have a lag in the sync time.
Currently I have create a dummy table just for the search with 2 columns: for the primary key to all the other tables and one for the update trigger.
I use the user_datastore with a procedure to join all the necessary columns resulting in a clob.
My question is regarding the update.
Of course I can create triggers to update the dummy field in the search table, but this will give lot of updates on that table with possible locking issues.
What would be the best approach to have this search functionality working?
I am open for any ideas!
Thanks,
Edward

Ok, I will focus on building a solution on 12c.
right now I have used a USER_DATASTORE with a procedure to glue all the field together in one document.
This works fine for the search.
I have created a dummy table on which the index is created and also has an extra field which contains the key related to all the tables.
So, I have the following tables:
dummy_search
contracts
contract_ref
person_data
nac_data
and some other tables...
the current design is:
the index is on dummy_search.
When we update contracts table a trigger will update dummy_search.
same configuration for the other tables.
Now we see locking issues when having a lot of updates on these tables as the same time.
What is you advice for this situation?
Thanks,
Edward

Which option to use to search text in multiple table columns

Hi, I have a case where I have 4 db tables. On the UI there is an option to search a keyword from some columns of these 4 tables.
Table1 = summary, description are the columns user can search on
Table2 = project_name is the column user can search on
Table3 = need_by_date is the column user can search on
Table4 = owner is the column user can search on
On the UI, user can enter a keyword and check the columns they want to search on. Out of the above, they can check one column, or more, or all.
My question is what is the best option to use oracle text search in this case.
Option 1 = I create a procedure to select these columns and then create an index on this procedure. In this case, is there a way to specify
which columns to search on?
Option 2= Create 4 separate indexes on these table/columns and then query the columns which user has selected to search on.
Any other better idea?

Hi,
multicolumn only works on columns in the same table.
If you can also query just on one field, then an index per field will be preferable. If you query always on all the fields then the one index approach is good. For this last the options are:
1. Use User_datastore, create a procedure and a dummy column
2. Create a materialized view for the query and build an index on this materialized view
3. Store the fields as an xml in the main table and index the xml column.
The maintanance of options 1 and 3 are bigger, because you need triggers to be aware of an update. Option 2 and 3 will need more storage.

SQL help - Parse Hyphen delimited text from UDF

Dear Experts,
I am experiencing a challenge that I hope you can help me with.
I have a requirement to create several separate UDF's to be populated with information from another UDF.
It uses a hyphen delimited string and I need to parse the different positions within the string.
Here is an example
UDF containing string
123-456-789-abc
needs to be queried to populate four UDFs separately.
UDF1 = 123
UDF2 = 456
UDF3 = 789
UDF4 = abc
There is no set number of characters in each segment as they are not based on a set criteria.
I have found ways to do this in SQL when not using the query generator however, I am given an 'Invalid Cursor' error whenever I attempt to use the code in B1 query generator
Thanks in advance and kind regards,
Lucas

Gordon,
This is the base statement I am trying to customize and build off of.
My assumption, is that if I can get this piece working in B1, I can modify with SAP object references and return the correct data for each UDF.
However, I may be going about this the wrong way, and I am definitely open to suggestions.
Thanks for any help,
Lucas

Is there a way to import/export tab delimited files to a table in Pages 2?

It seems like Pages is starting to get funtionality that might help wean me off of Excel. In this vein, is it possible to import or export tab delimited files to a table in Pages 2?

I had some success in Pages 1, but I've only tried a couple of times so far in Pages 2 without success. The trick was to make sure the table is the exact number of columns wide. It's very "klunky" but I've ended up converting the tab-delimited text to a table in AppleWorks, saving the AppleWorks file with the table as a "floating" object (fixed objects don't translate) & opening the file in Pages. It's quicker & easier for most of what I do to just drag & drop in Pages.

Export Excel Table in .txt File with space delimited text in UNICODE Format

Hi all
I've a big unsolved problem: I would like to convert an Excel table with some laboratory data in it (descriptions as text, numbers, variables with some GREEK LETTERS, ...). The output should be a formatted text with a clear structure. A very good solution is
given by the converter in Excel "Save As" .prn File. All works fine, the formattation is perfect (it does not matter if some parts are cutted because are too long), but unfortunately the greek letters are converted into "?"!!!
I've tried to convert my .xlsx File in .txt File with formatting Unicode and the greek letters are still there! But in this case the format is not good, the structure of a table is gone!
Do you know how to save an Excel file in .prn but with Unicode formatting instead of ANSI or a .txt with space delimited text?
Thanks a lot to everyone that can help me!
M.L.C.

This solution works in Excel/Access 2013.
Link the Excel table into Access.
In Access, right-click the linked table in the Navigation Pane, point your mouse cursor to "Export", and then choose "Text File" in the sub-menu.
Name the file, and then under "Specify export options", check "Export data with formatting and layout". Click "OK".
Choose either Unicode or Unicode (UTF-8) encoding. Click "OK".
Click "Close" to complete the export operation.

XML Column from table extract to Pipe Delimited Text File

Hi,
I have an XML column with large data in a Table ( Source SQL server Database).
I was asked to extract XML column to .txt file using SSIS.
Is it possible to extract xml column with huge data to text file ?
when I tried, select XML column from Table in source , I noticed that Property of column is taken as [DT_NTEXT] . I Converted it to DT_TEXT as Ansi donot support DT_NTEXT.
Execution method was success but it failed due to trucation. so wondering is there a way to get XML column extracted to Pipe delimited text file?
Is it advisable to do this ? or IS It Valid to export XML in Pipe Delimited File ?
Please Kindly advice
thanks
kodi

Are you looking at shredding data within XML nodes and then importing it to text file or are you looking at exporting XML value as is? Also is SSIS a necessity?
If not, You can simply use T-SQL for this along with bcp for this. just use a query like
EXEC xp_cmdshell 'bcp "SELECT CAST(XMLColumn AS varchar(max)) AS Column FROM table" queryout <full file path> -c -S <ServerName> -T -t |'
provided you use trusted connection (windows authentication)
see
http://visakhm.blogspot.in/2013/10/bcp-out-custom-format-data-to-flat-file.html
If you want to shred the data use Xpath functions in the query as below

FM to upload TAB DELIMITED TEXT file into Internal table.

Hello Friends,
The FM 'ALSM_EXCEL_TO_INTERNAL_TABLE' is used to upload EXCEL file into a Internal table.
Is there any FM which performs the simillar operation on TAB DELIMITED TEXT FILE.
Thanks in advance!
Ashish

Hi,
To upload text file with tab delimated you can use FM
GUI_OPLOAD.
In this function you have put X in the field HAS_FIELD_SEPARATOR.

Please recommend a tool or framework that parsing delimited text to XML

Working on a project that need me read data from delimited text file, the data will be converted to a tree-structure. So it's better parse the data into XML format first.
Besides j2se or jdom, any fast tool for it?
Thank you

Besides j2se or jdom, any fast tool for it?What do you mean with "j2se", that's not a XML handling tool (it contains several, 'though).
SAX sounds good for building object trees from XML, but there are several XML mapping libraries out there (try google).

Multiplication Table with Two Nested For Loops

I am trying to code a multiplication table in which the user enters the number of rows between 2 and 10 and enters the number of columns from 2 to 10. This must be in nested for loop format somewhat like this:
rows has been assigned the input variable for rows and columns is the name for input value for columns
for (int i = 1; i <=rows; i++)
for (int j = 1; j <=columns; j++)
i * j
i can't figure out how to get it to print out in table format or if the calculation coding is correct. can anyone help me please?
it should look like this for rows is 4 and columns is 7
1 2 3 4 5 6 7
2 4 6 8 10 12 14
3 6 9 12 15 18 21
4 8 12 16 20 24 28

Create a text index on multiple tables

I have read the same forum questions a thousand times about doing this and the only thing they show examples of is using multiple columns in one table.
Here is what I have:
create table documents_a
(id number,
text blob);
create table documents_b
(id number,
text blob);
create table documents_c
(id number,
text blob);
I want to be able to do a text search over all three tables on the blob column. I can't use the multi_column_datastore because from what I read this can only be used with one table.
I eventually want to be able to bring up a snippet of the text that contains the keywords and a link to the actual document.
How do I build a text index that includes each blob column from each of the three tables?

OK so I created the materialized view
create materialized view alltabs as
select a.id, a.text, b.id, b.text, c.id, c.text
from tablea a, tableb b, tablec c;
and I created the following
ctx_ddl.create_preference(my_multi', "MULTI_COLUMN_DATASTORE');
ctx_ddl.set_attribute('my_multi','columns','a_document, b_document, c_document');
Then I attempted but I am not sure what column name to put in the pararens?
create index multi_tab on alltabs(????)
indextype is ctxsys.context
parameters('datastore my_multi sync(on commit)');
I saw a dummy column created in most of the internet examples but just exactly what gets created here? I want to create a multi column index so didn't I already tell it which columns up above?

"Failed to open the connection" problem related to multiple tables in the report?

Post Author: Gadow
CA Forum: Data Connectivity and SQL
System specifics:
Web environment using ASP.Net 2.0 (from Visual Studio 2005 Professional)
Crystal Reports 2008, v. 12.0.0.549, Full
We have set up the following method for displaying reports via our website:
User is sent to a report-specific page. The user is given some filtering options specific to the report that will be viewed. When the user has specified the data filters, the user clicks a button.
The page wraps up the report parameters -- selection query, formula values, report location, the name to be displayed, etc. -- into a class which gets put into the Session object.
The page redirects to DisplayReport.aspx. ALL reports redirect to this page.
DisplayReport.aspx retrieves the report parameters from Session. A ReportDocument object is created and loaded, then set with the data from the parameters class.
A ConnectionInfo object is created and set with the relevant log on credentials. All of the reports draw from the same database, so the connection information is hard-coded as the same for all reports. The page then iterates through all of the tables in the Database.Tables collection of the ReportDocument and calls ApplyLogOnInfo to each table using the ConnectionInfo object.
The page is rendered and the user gets the filtered report.
We currently have seven reports. Five reports work fine and display the correctly filtered data with no error messages. Two reports generate a Failed to open the connection error and do not display. I have verified that the queries being sent to DisplayReport.aspx are valid, and as I said the connection information itself is hard-coded in the one page that displays the reports and this is identical to all reports.
The five reports that do work all have a single data table, either an actual database table or a single view. The two reports that do not work all have multiple tables. As far as I can tell, this is the only difference between the sets; all seven reports are based on the same DSN and I have verified the database on all of the reports. All of the reports were written using Crystal Reports 8, and all of the reports display fine in a Windows app I wrote some years ago using Crystal Reports 8. Again, the only difference between those reports that do work and those that do not is the number of tables used in the report: one table or view in the reports that display, more than one table (tables only, none use views) in the reports that do not display.
As for the code I am using, below are the relevant methods. The function MakeConnectionInfo simply parses out the components of a standard SQL connection string into a ConnectionInfo object. DisplayedReport is the ID of the CrystalReportViewer on the page.Protected Sub Page_Init(ByVal sender As Object, ByVal e As System.EventArgs)

hi John
you can create a join of those multiple tables in an internal table
and then u can view that on this single internal table....
like:-
example
SELECT c~carrname
              p~connid
              f~fldate
INTO CORRESPONDING FIELDS OF TABLE itab
    FROM ( ( scarr AS c INNER JOIN spfli AS p
                  ON pcarrid   = ccarrid
                  AND p~cityfrom = p_cityfr
                  AND p~cityto   = p_cityto )
         INNER JOIN sflight AS f ON fcarrid = pcarrid
                                AND fconnid = pconnid ).
LOOP AT itab INTO wa.
WRITE: / wa-fldate, wa-carrname, wa-connid.
ENDLOOP.
