PL/SQL :: Query Pull Only Fields That Contain Data
Aug 9, 2012
In the database we use for transfer articulation, there are numerous tables delivered with the product. The institution decided not to use certain fields, and all instances of those fields have no data. In other words, there might be a field in the table called INSTCD, but no records in the table have ever inserted any data into that particular field. In the table there are thousands of records, and we don't necessarily know which of the fields have never been used (no list has been retained and no one who initially was involved in the decisions is available to ask), as there are multiple fields in each table. How can I write a query that pulls only the fields in the table that contain data. In the example below, the SHRTRIT table contains a field called ACTIVITY_DATE, but there is no data in any record in that particular field, so I don't want it to show up on the output. In this particular case, I KNOW not to pull this field in a SELECT, but in a case where there might be 130,000 records and I DON'T know if a field has records in it, how could I do that?
if the question I'm asking doesn't make sense and I'll attempt to word it better.
I am having trouble trying to pull the next value from a query based on a where clauseThe query I am using is:
Declare nextID NUMBER(22);BEGINselect lag(ref_contact_id, 1,0) OVER (ORDER BY ref_contact_id)into nextID from (select ref_contact_id,lead(ref_contact_id, 1,0) OVER (order BY ref_contact_id) as "NextNbr", lag(ref_contact_id, 1,0) OVER (order BY ref_contact_id) as "LastNbr"from (select rc.ref_contact_id from REF_CONTACT rc order by FIRST_NAME ))where ref_contact_id = 793 ;END; The returned value is 0.
I understand why but not how to pull the next value base on a particular ref_contact_id.
I'm needing to pull data into a cursor, then split this data into 3 different tables, each having the same number of rows and a select number of columns from the original. i can pull the data, but then i can only access it one row at a time via FETCH, then i can't load into the 3 new CURSORS one row at a time.
I am writing a query where I'd like to pull one year's worth of data. Ideally I want to prompt for the END DATE and have the query go back in time one year from that date.
Here is what I've got after doing some research online... but It's not quite working for me.
select * from mrtcustomer.profile where reg_type = 'B' and contact_type = 0 and active_ind = 'Y' [code].....
DIDDOB_INFO(VARCHAR2) 34425 Mar 1967 123 12 MAR 1963;25 FEB 1974;25 AUG 1978 46515 FEB 1980
I want to join the columns DOB from table -1 and DOB_INFO from table 2 but the datatype of DOB is DATE and DOB_INFO is VARCHAR. TO_DATE function is not working here.
I am using the dbms_xmlgen.getXMLfunction to get the result of any query in xml format.
With this XML I also want the metadata information about all the fields used in the query (passed to getXML function). Is it possible and how can I achieve this.
I tried to Google it but couldn't find any solution , it's easy to do it in java where I can get the resultset meta data from the resultset but I have to do it in Oracle function since I want the result in xml format and want to use the oracle XML API.
You may think why I need metadata , the reason is the application will later use this information to sort the data contained in these fields according to their data type provided to.
I got that error bur I checked all the fields on RG query and they are not more 300 char in total. Even I changed the query but I still get this error.
Something strange happens when i give execute query in a form (Oracle Forms 10g.). On executing query, one field disappeared but when i clicked on the location of the field it appeared again. I am not sure if this has something to do with visual attributes/display properties. This is happening only after migration to 10g.
We are using Oracle 10g, on redhat linux (version not known to me).I'm running a Perl script that reads in data from Visual FoxPro tables, creates datafiles on the fly from these FP tables, then SQL-Loader runs and uploads all the data to matching tables in Oracle.
Problem:My upload runs, but I'm not getting the data in some of the fields that I should be. It is being uploaded to the wrong fields.
I had to add more columns to the Oracle tables in order to capture the data coming from FoxPro. These columns were/are in FoxPro. In the past, they were not needed in Oracle. I was using the FILLER command in the Control files to skip these. Now they are needed in Oracle. The new columns get added to the end of the table in Oracle, so they are not in the same exact order they are in FoxPro. It is these new columns that are not getting the correct data.
I've learned in the past that I need the fields/columns in the control files to match the order they are in the FoxPro tables from which the data comes. My Question is, Does the Oracle table column order have to match the Control file column order. Like so: FoxPro table column order = control file column order = Oracle table column order
I have 2 questions, because they can be inter-related I am posting it in a single post. These queries are related to Oracle(PL\SQL).
1. I am trying to increase the size of a field in a table which has almost 2 million records and the query for alteration runs for almost and hour and rollsback, wondering is there a better way of doing it.
2. I have modified the size of a field in a table from Varchar2(10) to Varchar2(20), now when I tried to rollback the modification it is not letting me to change the size from Varchar2(20) to Varchar2(10). No data has been inserted after the modification.
I have a horrible problem with EBS (actually, all problems with EBS are horrible) and I think I am stuck because of my ignorance of Forms. if I use terms that are not correct in the Forms world. The form consists of a number of named "blocks" and each block consists of a number of named "fields", not all of which are visible. I need to find the source of the data values in one of these fields. I have searched every table for a column of that name, also all the views and stored PL/SQL that I think might be relevant, but I can no find no mention of a column or variable with the same name as the field. The name does not get a hit in the online EBS tech ref manual, and only two ancient and irrelevant hits in MOS.
My question is: What are the possible sources of data for a field in a form? Have I missed any?

I developed a custom Form using Form Builder 6i. This Form has selection criteria (data to be entered in a couple of fields) and a "Find" Button, which queries the data (based on the selection criteria) and populates all fields on the Form.
This Form has a couple of "Required" fields in its search criteria section. When data is not populated in any of the Required fields and "Find" button is clicked upon, Form raises an exception and pops up a message indicating the user 'to enter data in mandatory fields'. However, this message keeps popping up and would not stop.
So, I'm not able to proceed with querying data on my custom Form. I had to kill the session and reconnect to front end to overcome this issue.
I know how to append fields to text, but how do I deal with the variable length? I want to place text on a report and inside the text I have data from two different fields. It works great except that my fields are 35 characters long. If the data fills the entire field it looks great, if the data is only 10 characters long, I have a huge gap between the end of the data and the text that follows. How do I fix this?
I have a editing database with an eversions table:
NAME OWNER ---------------------- -------------------------------- WR5936_DN6676 FRED WR6739_DN7507 FRED WR12744_DN13994 FRED WR6739_DN7511 BARNEY WR6801_DN7513 BARNEY
I have a process database with a pversions table:
SOID ---------------- 5936 6739 12744 6739
I need to select from the editing.eversions table all the records that do not have a matching record in process.pversion. The eversion table is text, and has some additional crap surrounding the characters I want to use for creating a join.
I'm trying to change the attributes on a display where the info is gathered via a routine that fills the data block with info. I've searched and tried using 'set item instance property' in several places within the data block using different triggers but still doesn't work.
No errors are encountered or shown. Attributes aren't changed based on a small test condition.
i load data to this table from a file using sqlldr.
what is the proper data type should i use in control-file for both the fields.? i dont mention any datatye in ctl file which is working fine with given dataset.
using SQLLDR: Looking for a control file solution to move past or bypass extra data fields which are not on destination table. Basically if you have 8 tab delimited fields(terminated by ' ') on a data record; but only need to load 5 of the values from the delimited record; is there a way to ignore/bypass the not needed data. Obviously, the answer would be to massage the data at the OS and removed the 3 unnecessary fields.
However my hands are tied by volume,time, and compliancy. I am familiar with using 'FILLER' for the reverse scenario; but not where you have more data available on the record then exists on the table.
I want to start by saying I am brand new to SQL. I have an access database linked to my oracle and am trying to query a very specific set of data and I can't seem to narroe it down. I have 244,000 lines in the DB and I'm trying to find items on a specific trype of vendor agreement. I may have the same item on multiple agreements. ex 1-, 1a-, 2-,2a-,3-,3a-,4-,4a-,5-,5a-,6-,6a-,7-,7a-,8-,8a-.
I need to find a way to select just items that appear on a 4- or 4a- and no other agreement reference. The query I did so far pulls all of the 4- and 4a- agreements but will also pull items,like #233 in the example above, but not showing the 1a- agreement. I need it to overlook that item eventhough it does appear on the agreement I am looking for but also has an agreement I am not. the statement I am using right now is:
SELECT item, ven_item, ven_agrmt_ref, base_cost, vendor FROM "all items by agreement" WHERE ven_agrmt_ref >= '4' ORDER BY item
I want to move data between two instances and recommended we create a local database link to PULL data from remote database located here (supplier on site) but they want to PUSH data to us. I thought you could only PULL data over a database link but then read the link [URL] where PUSH is considered ? I was going to use standard creatas like create table A as select * from table A@<remote_db_link> which works well and fast ( tried and tested) but some are saying they think PUSH quicker/better ?
we do have data "PUSH" already but this does not use a db link - effectively it calls a local proceedure here and passes a row of data and is slow ie for a 1000 row table to be pushed to us we have our local proceedure called 1000 times.
I have always suggested a PULL with db_link as the fastest method - any proof OR info on a fast PUSH method ( that is quicker than PULL ) ? can you REALLY push ?
I'm trying to pull all the degrees into a table based on which institution is selected. If institution is 'AAA' or 'BBB' then pull ACAD_PLAN, DESCR by ACAD_PROG where ACAD_PROG >= some value and <= some other value.
If institution is 'CCC' then pull ACAD_PLAN, DESCR by institution regardless of ACAD_PROG.
Something like
INSERT INTO table SELECT 'value_a'

I don't have this formatted right cause it keep telling me missing keywords.

I have an Oracle 10g database, on the App Serv I have an image file that has 20,000 .jpg files that has an id number as each image name.I have successfully queryed the image file and posted one image to my web page matching the image id number. sample:
the &1 is the matching id number that is input from the user.My task now is to select multiple images using a department field in the spriden table to pull the needed id numbers.I have not been successful in the proper format to pass the id number to the <img src field.
I have data in a table and another in XML file,I used SQL query to retrive the data placed on the table, and link this query with XML query that retrieves the data stored in the xml file. The data stored in the table and xml file sharing a key field, but the xml contents are less than what in the table.I want to show only the data shared between the two queries, how can I do that?
e.g.:
Table emp:
e_id | e_name | e_sal 023 | John | 6000 143 | Tom | 9000 876 | Chi | 4000 987 | Alen | 7800
