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 need to store a date that will always be x years before the current date. Is doing something like
select sysdate -x from dual
Going to result in any weird issues down the road? Also, because I haven't explicitly specified the date, when queried, will the value always be sysdate - x (What I want to happen) as opposed to dateRowWasCreated - x?
I have a requirement like getting list of values from one table and inserting them into another table.I have tried with sub querying but didn't worked out because the select query is returning multiple values.
how to proceed further and the ways how can I write this requirement.
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)?
I need to transpose this table to below one. But since my rows in 1 table is dynamic and it will increment each week and month I couldn't get a correct result from unpivot.
i am practicing to get Dynamic columns as i have learnt from Orafaq SQL/PLSQL forum .i am using Default EMP table...first one is running smoothly as below:
I need to write a dynamic SQL in PL SQL to query an unknown number of columns. Let me take a simple example query here:
SELECT FIRST_NAME, LAST_NAME FROM VENDOR_CONTACTS
If I have known the number of columns, e.g. querying two columns: "FIRST_NAME" and "LAST_NAME", I can write a DYNAMIC SQL based on the template in table 8-2 of URL....
DECLARE stmt_str varchar2(200); cur_hdl int; rows_processed int; FIRST_NAME varchar2(200); LAST_NAME varchar2(200); BEGIN cur_hdl := dbms_sql.open_cursor; -- open cursor stmt_str := 'SELECT FIRST_NAME, LAST_NAME FROM VENDOR_CONTACTS'; [code]....
However, if I wish to write a dynamical sql to query these two columns for a more general purpose (which should meet the requirement to query different number of columns, e.g. three columns, FIRST_NAME, LAST_NAME, BIRTHDAY instead of two columns FIRST_NAME and LAST_NAME). To do this I first try to query the same two columns but using a different method, following URL.....My code for the same query has error, and I cannot solve it.
I have a web page written by pl/sql and html which some jpg files are published. Currently they are linked by html from a directory source. There are almost 70000 files which makes 1.15 gb. I want to store them in our oracle database but I have never done this before.
What I want to learn is how will be the performance for selecting from many jpg files with select statement and how much space would they keep in the database?
I have two string one is comma separated values as a column name and another string which is having the comma separated value corresponding to the column name.
T1 is having 2 columns t1_c1, t1_c2 T2 is having 3 columns t2_c1,t2_c2,t2_c3
I need to design a form which should be like
there must be a pop item (Dropdown menu) in a separate block.
If I select 1 from the pop item, T1 with 2 columns should display in a tabular form. If I select 2 from the pop item, T2 with 3 columns should display and T1 with 2 columns should hide.
So the form should be dynamic based on the selected pop item. Is there any chance to do this?
I am working on Oracle forms 10g (Windows 7 OS).I have got one requirement to show one LOV for COLOR table. Say i have three colors BLACK, RED, BLUE in color table. Suppose in a multi record block if a user selects BLACK from a lov for one record then for the next record lov it should show only RED and BLUE. How to filter the COLOR from a LOV record group query which are already selected?
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?
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.
I have a scenario to frame an xml as below, below i have given a sample data
Create table xml_type (msg varchar2(1000), desp varchar2(1000), val number) ;

Actually i need the output as below, i tried and succeeded doing it in Procedure , but they are asking me to do it in SQL query. How to get from an sql query.
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.
