SELECT CASE WHEN "PIVOT_ROW_GENERATOR"."ID" = 0 THEN "PIVOT_SOURCE"."ID_NUMBER" WHEN "PIVOT_ROW_GENERATOR"."ID" = 1 THEN "PIVOT_SOURCE"."ID_NUMBER" [code].........
I have seen lots of examples of using PIVOT to return an sql query where the rows have been converted to columns. All the examples I can find require you to have two columns with multiple rows, and also require you to know the data which is in one of columns to make titles for the new columns.
I need something a little different...I have a query using UNION which goes something along the lines of...
SELECT [get data from one place] UNION SELECT [get data from another place] UNION SELECT [get data from another place]
this returns the following... a_val ----- 100 200 300
query to return something like this... a_val1 a_val2 a_val3 ------ ------ ------ 100 200 300
The names of the columns don't really matter. And I dont want to create a new table in the database just for the result.
I Have a table like this. 12 rows and 8 columns.And column 1 Dt is going to change everytime,as date and months proceeds.and corresponding columns values are going to change.
Is it possible to communicate with a serial device (via COM1) with oracle forms / webutil? I am able to communicate in java using RXTXcomm, but I am having problems making a bean that uses it (getting security errors and yes, I have signed the jars).
Basically, I have a scale hooked up to my COM1 port and want to be able to send commands (zero and tare) to it and read the weight from it through a form or java bean.
I have a table A, whose table structure is in the below format.
Table A
ID DESC VALUE 123 A 454 123 B 1111 123 C 111 123 D 222 124 A 123 124 B 1 124 C 111 124 D 44
Now i need to insert the data from this table to another table B, the sturcture of which is as below
Table B
ID A B C D 1234541111111222 124123111144
How do i frame a query to fetch data from table A and insert that into table B? I don't want to use max and decode combination. as it would return only single row for an ID. I need all the id's to be displayed.
My scenario is to insert values into 'out' column by comparing 's' and 'IP' columns of temp table.The exact situation is at first need to go to ip column,take a value and then go to source column and check for the same value of ip which is taken previously.Then after corresponding ip of that source column should be inserted back in previous source column.
The situation is marked clearly in file which i am attaching with '--' comments at respective places.I am also pasting the code which i tried out,unfortunately it is giving error as exact fetch returns more than requested number of rows since there are duplicates in the table.I tried it using nested for loops.Also implemented using rowid,but it didnt work.
fixing the errors or if there is any new logic that can be implemented.
DECLARE i_e NUMBER(10); BEGIN FOR cur_1 IN(SELECT IP from temp where IP IS NOT NULL) LOOP FOR cur_2 IN(SELECT IP from temp where s=cur_1.IP)
From two given tables, how do you fetch the values from two columns using values from one column(get values from col.A if col.A is not null and get values from col.B if col.A is null)?
We are working on a migration project and we need to move 75 million rows from source system to target system.
Total number of columns in source system - 90 cols.
Out of the 90 columns 10 cols are system fields and rest 80 are properties for each record.
We are required to migrate all system cols and some required properties. In total we will migrate around 25 columns[10+15] for each record.
Before actaul migration , we need to do a data cleansing activity and hence we move the data to a staging table.
To create the staging table, we considered the below appraoches.
1. Create the staging table with around 30 coloumns so as to fit the data from source system[map the columns based on datatype]
2.Create the staging table with actual columns[90 columns] and import only the required properties. The rest all columns will remain NULL.
Do the data cleansing and move to target system.
My question here is, if we go with approach 2, We will not mix the data, as there will be a one-to-one mapping. But many columns will not have data and remain NULL. Will it affect the performance since we deal with 75 million rows.
I need to add values of one column values from a table to another table each value as a column. Below i am considering only for 3 values in real time i have more than 50 values
CREATE TABLE TEST_REG ( VAL VARCHAR2(1));
INSERT INTO TEST_REG VALUES ('A'); INSERT INTO TEST_REG VALUES ('B'); INSERT INTO TEST_REG VALUES ('C');
CREATE TABLE TEST_HOLD ( COL1 VARCHAR2(1),COL2 VARCHAR2(1),COL3 VARCHAR2(1)); -- in realtime i have 100 columns
I want to get the values and put them into html template since i want to configure mime settings. My table's name is rawticket_voip and it has 150.000rows and 20 columns so instead of COL1, COL2 what should i write there? How can i get the spesific row's and column's value and how can integrate loops in this html?
In col4 , we have to update the values of col3 (column) ... it is very easy to update the values by executing the query for each column but my requirement is ... I want to execute the query once for a table ( example select col1_abc,col2_abc from table_abc ... this will return always a single value after adding other conditions in where clause) and why I want to do this? .. because there can be multiple (might be 30 variables values) from a single table.
I have converted the columns into rows by using listagg function now I have lets a dynamic query ( for the above example).
for i in 1.2 loop
l_query := ' select col1_abc, col2_abc from table_abc'; open c1 for l_query;
end loop;
my problem is : how to hold these values and update the above table?
I've recieved a recent request wherein the requirement is to swap values between columns across multiple tables in a database.Following is a visual sample of what needs to be done.
I am working on a form having three data blocks Travel_Inconvineance (Master) TI_Card_Info (Detail) TI_Limit_Indemnity (Detail)
On working TI_Card_Info i have 2 columns Plastic_Card_Id and Plastic_Card_Type which i want to be paste on TI_limit_Indemnity data block as i enter in TI_Card_Info.
how to assign values from a "rule table" to a rowtype-variable. The ruletable contains values for different columns in different tables.Now i need to assign those given values for given columns out of that rule table to the equivalent column in a rowtype-variable.

My requirement is to concatenate two column values and place them in a new column.I have done it using self join but it limits the purpose,meaning when I have more than 2 values for grouped columns then it won't work.How to make this dynamic,so that for any number of columns grouped,I can concatenate.
SELECT a.co_nm, a.mnfst_nr, a.mnfst_qty, a.mnfst_nr || ':' || a.mnfst_qty || ';' || b.mnfst_nr || ':' || b.mnfst_qty FROM vw_acao_critical a JOIN vw_acao_critical b ON a.co_nm = b.co_nm AND a.mnfst_nr = b.mnfst_nr [code]......
What will be the case when I need to concatenate for more number of values.
like when co_nm has three bahs and manfst_nr and manfst_qty has 3 values for each for bah.and if three are having same_mnfst nr then I should use something dynamic.how to achieve this.
There are at most 2 entries of a in b. Depending on the value of the type column in B, this determines whether the entry should be male or female. I want to have a select statement that will retrieve 2 rows into one row essentially like below, how is this done:
id male_name female_name 1 paul paula
the column names will appear as such, if its a 0 its a male name if its 1 its a female name, there will generally be 2 entries in B for 1 value of a.
I want to create a report by using one field and one text as columns name in layout but display the all the columns. I mention the 5 column names in query.how can I write function in summary column.
I am running a fairly busy Oracle 10gR2 DB, one of the tables has about 120 columns and this table receives on average 1500 insertions per second. The table is partitioned and the partitioning is based on the most important of the two timestamp columns. There are two timestamps, they hold different times.
Out of these 120 columns, about 15 need to be indexed. Out of the 15 two of them are timestamp, at least one of these two timestamp columns is always in the where clause the queries.
Now the challenge is, the queries we run can have any combination of the 13 other columns + one timestamp. In reality the queries never have more than 7 or 8 columns in the where clause but even if we had only 4 columns in the where clause we would still have the same problem.
So if I create one concatenated index for all these columns it will not be very efficient because after the 4th or 5th column the sorting would no longer be very useful and I believe the optimiser would simply not use the rest of the index. So queries that use the leading columns of the index in sequence work well, but if I need to query the 10th column the I have performance issues.
Now, if I create multiple single column indexes oracle will have to work a lot harder to maintain all these indexes and it will create performance issues (I have tried that). Besides, if I have multiple single column indexes the optimiser will do nested loops twice or three times and will hit only the first few columns of the where clause so I think it will kind of be the same as the long concatenated index.
What I am trying to do is exactly what the Bitmap index would do, it would be very good if I could use the AND condition that a Bitmap index uses. This way I could have N number of single column indexes which the optimiser could pick from and serve the query with exactly the ones it needs. But unfortunately using the Bitmap index here is not an option given the large amount of inserts that I get on this table.
I have been looking for alternatives, I have considered creating multiple shorter concatenated indexes but this still would not address the issue since many queries would still not be served properly and therefore would take a very long time to complete.
What I had in mind would be some sort of multidimensional index, I am not even sure if such thing exists. But essentially it would be some sort of index that could serve a query efficiently regardless of the fact that the where clause has the 1st, 3rd and last columns of the index.
So considering how widely used Oracle is and how many super large databases there are out there, this problem must be common.
There are millions of DISTINCT ID values in TABLE_1 and corresponding to each ID there are some values for all the days of a month. I need to insert these values in TABLE_2 in the above format.
select * from function('input') where the function dynamically returns different tables.
I have gotten to the point where I can return the cursor but I cannot format it as a table to use in the query. It return's it as XML. This is my function:
create or replace FUNCTION CAMS_FUN_GEN_REPORTS(PARAM1 IN VARCHAR2) RETURN SYS_refCURSOR AS BEGIN DECLARE p_recordset SYS_refCURSOR; begin OPEN p_recordset FOR 'SELECT * from STATS_FLAGGED_TOTALS_ME'; RETURN p_recordset; END; END CAMS_FUN_GEN_REPORTS;
This is my query:
select * from CAMS_FUN_GEN_REPORTS('')
So normally you would do this
select * from TABLE(CAMS_FUN_GEN_REPORTS('') as tabletype)
But I will never know the end result table as it will be dynamic so I have to find a way to cast the result of the function into a new table I can select on.
I have looked into pipe lining also but from what I can tell you still need to know the table definition. Which I can't know from the client side. The server will control the 'routing' and thus the end result of the select.
We are able to insert CLOB into database, Using oracle Text I'm able to search inside clob. [two questions solved ]. The question arise when we need to send this data to application either as file or as text(varchar2).
I'm able to generate file from CLOB using function,unfortunately it resides inside db and developer is not able to access it.
1)There is option to mount application partition inside db and export file over there but it is not viable option according to management.
2)I've Googled the solution to create JAVA API. Which will perform OS command like scp to send file from db to app(or any remote host). For security reason this option is also dropped.
3)I tried dbms_lob.substr but actual text inside clob is too long. File generated from CLOB sized around 5 MB.
So I guess it requires lot of effort if I wanted to convert into varchar2 as out parameter inside function.
So, to give CLOB data to developer as file or as varchar2. I'm not able to get any solution. Is there any other option using database to convert to string/varchar2 from CLOB ? Or do I need to drill down more into third option.
I am converting from 10g to 11g app server and having problem with the exec_sql.execute command. In my 10g version, the code is:
Declare lv_dbms_journal_cursor exec_sql.curstype; lv_status INTEGER; BEGIN IF (exec_sql.IS_OPEN (lv_dbms_journal_cursor)) THEN exec_sql.close_cursor(lv_dbms_journal_cursor); [code].....
After this code caused the 11g forms session to crash, I modified the 11g version to the below, and it still crashes.
