SQL INTO union-clause

SQL help

If any of the queries Union returns a value, I would like to mark as closed status. How can I put the INTO clause in this case because of two queries. Thank you

BEGIN

SELECT 1

FROM TableA your
WHERE tA.col1 = 13
AND tA.col2 = '100'
UNION
SELECT 1
TB from TableA
WHERE tb.col2 = 'y '.
AND tb.col3 = - 123
AND tb.col4 IS NOT NULL;

status_cd: = 'closed ';

EXCEPTION
WHEN NO_DATA_FOUND THEN
status_cd: = 'Unknown ';

END;

Hello

Here's one way:

BEGIN

SELECT 'closed '.

IN status_cd

FROM tablea

WHERE ((col1 = 13

AND col2 = '100'

)

OR (col2 = 'y')

AND col3 = - 123

AND col4 IS NOT NULL

)

)

AND ROWNUM = 1;

EXCEPTION

WHEN NO_DATA_FOUND

THEN

status_cd: = 'Unknown ';

END;

APPEND INTO TABLE test1

trailing nullcols

    But it does not work. It works fine if I give a direct value like PARENT = 'P '.

    Any idea how compare the 2 fields while the conditional support?

    You can't compare 2 fields with the WHEN clause in SQL * file the charger control.
    only literal values as defined by the syntax:

    http://docs.Oracle.com/CD/B19306_01/server.102/b14215/ldr_control_file.htm#i1005657

    As already suggested, you'd be better to load data using an external table which allows to apply conditions you want in your SQL query, which is to get the data.

  • -SQL - GROUP BY clause: fields of nonaggregate mandate

    Hello

    I study data (especially data recovery) and found something interesting.

    When you use an aggregate function in the SELECT clause, it is mandatory to have all fields that are not aggregated in the SELECT clause to be there in the GROUP BY clause.
    For example,.

    SELECT dept_no, Salary
    The EMPLOYEE
    GROUP BY dept_no;

    The SQL above works fine.
    But what happens if the user forgets the dept_no in the GROUP BY clause or the clause GROUP BY itself is missing?
    Certainly, it is a mistake.

    Why this error is not handled by the database. I mean, the database must be smart/pretty smart to add the GROUP BY clause by itself. So let's assume that, if I miss the GROUP BY clause or miss a field no aggregated from the SELECT clause when I get at least an aggregate function on a field with at least a no aggregated field in the SELECT clause, the database should check the GROUP BY clause at compile time and add mandate missed the fields in the GROUP BY clause.

    Example,

    SQL1:_
    SELECT dept_no, Salary
    The EMPLOYEE
    GROUP BY dept_no;

    SQL2:_
    SELECT dept_no, Salary
    The EMPLOYEE;

    Here, the SQL1 and SQL2, both should give me same output without error.

    I can't understand why this is handled?

    Hello

    998478 wrote:
    ... If we mix the aggregated and non-aggregated values, then there must be a GROUP BY clause that contains all non-aggregated values. Why this is handled by the database/compiler itself?

    It IS managed by the compiler itself. The compiler manages to trigger an error. The compiler has no way of knowing if you want to remove something from the SELECT clause, or add something to the GROUP BY clause, or not to use the aggregate functions or use several aggregate functions, or a combination of the above. If the compiler re-writes your code and none of these things done automatically, it would be wrong more often that he was right, and you would (rightly) complain about his behavior.

    For example, it is clearly wrong:

    SELECT    deptno
,       job
,       SUM (sal)
FROM       scott.emp
GROUP BY  deptno
;

    What is the right way to fix it?

    1. remove something from the SELECT clause

    SELECT    deptno
,       SUM (sal)
FROM       scott.emp
GROUP BY  deptno
;

    2. add something to the GROUP BY clause

    SELECT    deptno
,       job
,       SUM (sal)
FROM       scott.emp
GROUP BY  deptno
,         job
;

    3. do not use aggregate functions

    SELECT    deptno
,       job
,       sal
FROM       scott.emp
;

    4. use several aggregate functions

    SELECT    deptno
,       MIN (job)
,       SUM (sal)
FROM       scott.emp
GROUP BY  deptno
;

    What are all the options, either. For example, the correct solution would be to use analytical functions instead of aggregate functions.
    How can anyone tell which of them is right? They all have the right answer for some problem.

    Moreover, by saying that everying in the SELECT clause must be an aggregate or in the GROUP BY clause is a bit oversimplified.
    Fuller, here's the ABC of GROUP BY:
    When you use a GROUP BY clause or in an aggregate function, then all in the SELECT clause must be:
    (A) a ggregate function,
    (B) one of the expressions "group By."
    (C) adding to C, or
    (D) something that Depends on the foregoing. (For example, if you "GROUP BY TRUNC (dt)", you can SELECT "TO_CHAR (TRUNC (dt), 'Mon - DD')").

  • SQL Loader / WHAT clause / off swich? / bloated log files

    Hello everyone,

    I'm loading data using SQL-Loader very large source files. It all works very well.

    However, now, by using the WHEN clause (in the control file), I would like to only a very small subset of most load data. This also works very well...

    WHEN ARTICLECODE! '000000000000006769' =

    However, the log file becomes fully inflated with messages telling me to each record that does not have the WHEN clause...

    Record 55078: Discarded - failed all WHEN clauses.

    This becomes a problem because it slows down the process and creates large log files that eat upward of my disk space.

    There must be a simple command to allow me to disable the messages of thiese, but although I googled on it, I could not find it.

    Any ideas on this one? I don't know that it's simple.

  • How to handle multiple formats of date to the same date field in SQL * Loader

    Dear all,

    I have a requirement where I need to get data from a text file and even insert into the oracle table.

    I'm using SQL * Loader to fill data from the text file in my table.

    The file has an area where I expect to date data date in different formats, such as MON/dd/yyyy mon/dd/yyyy mon/dd/yyyy, dd/mm/yyyy, DD/month/yyyy.

    When you use SQL * Loader, I can see loading fails for records where we have formats such as LUN/jj/aaaa, Mon/dd/yyyy, DD/month/yyyy.

    Is it possible in SQL * Loader where we can mention all these date formats so that data from that date should go smoothly in the underlying date column in the table.

    Receive your answer on that.

    Thank you
    Madhu K.

    I think following could be the solution to your problem:

    Suppose if you have data from four different date formats, you need to load the data into four different tables by running SQL * Loader four times and each time specify other date format in the control file whose data to load, and then at the end, merge data from these four different tables using the UNION clause.

    Could someone please take a look and advise? My apologies that the files cannot be attached.

    Unless you tell it otherwise, SQL * Loader assumes that each later in the table and what clause after the first back in the position where the previous left off.  If you want to start at the beginning of the line every time, then you need to reset the position using position (1) with the first column, as shown below.  Position on the first using is optional.

    The use_concat flag may be appropriate.

    https://docs.Oracle.com/database/121/SQLRF/sql_elements006.htm#BABIAFIB

    The USE_CONCAT index tells the optimizer to transform handset OR -the economic situation in the WHERE clause of a query in a composite application using the UNION ALL fixed operator. Without this indication, this transformation only occurs if the query using concatenations is less expensive than the cost without them. The USE_CONCAT Council overrides consideration of cost. For example:

    SELECT /*+ USE_CONCAT */ * FROM employees e WHERE manager_id = 108 OR department_id = 110;
