SQL : Select clause

Hi all..
In open sql, is it impossible..?
Select a~*
    into table gt_mara
    from mara as a inner join marc as b
    ~~~
For performance, I want to fetch the fields of table mara. But, while compiling, occur error..
How to do..? What to do..? tell me plz..
Thank you!!
regards..

Hi Kil,
Just an addition to the prev post..
Avoid the "into corresponding fields" for performance reasons... as long as the fields in the internal table are in the same order, use the below clause..
Select *
into table gt_mara
from mara as a inner join marc as b
ON amatnr = bmatnr.
Rgds,

SQL Query : Getting specific datatype in select clause

Hi
I want to write one query that returns me the values inside a table based on the datatype of column(s) of the table. For e.g. I need only those columns of the table in select clause where the datatype of the column is VARCHAR.
Can you please help me on this?

Use the "user_tab_columns" Data Dictionary to get the columns and build the SQL Dynamically.

Decimal Separator in SELECT Clause

Hi
I have the following decimal format parameters:
SQL> select value
2 from v$nls_parameters
3 where parameter = 'NLS_NUMERIC_CHARACTERS';
VALUE
If I show a number with decimal I get a comma as the decimal separator
SQL> select 10/100 from dual;
10/100
,1
But if I use a decimal separator in the SELECT clause I get:
SQL> select 100 * 1,1 from dual;
100*1 1
100 1
It doesn't work. But using a period as the decimal separator works:
SQL> select 1.1 * 100 from dual;
1.1*100
110
Maybe this is something I've never had to deal with before but I thought that the numeric format applied to the sql results and also the numbers that you used in the sql clauses.

Hi,Néstor,
user594312 wrote:
... I thought that the numeric format applied to the sql results and also the numbers that you used in the sql clauses.No; it applies to results, and it can affect implicit conversions, but it doesn't apply to SQL code.
The period (or dot, '.') is always the decimal separator in numeric literals. There is no way to change that.
Think how confusing it would be if it did apply to SQL code! For example:
WHERE   num_col IN (1,2)Are we comparing num_col to 1 value or 2 values? Whichever it is, what if we wanted to do the opposite?
If you really wanted to use comma as the decimal separator, you could have to use strings, not numbers, and that could be a lot less efficient.
For example:
SELECT 100 * TO_NUMBER ('1,1')    -- This assumes your NLS settings are correct
FROM    dual;Of course, efficiency won't be an issue when you're selecting 1 row from dual.

Help with SQL MODEL Clause

I have the privilege of performing a very tedious task.
We have some home grown regular expressions in our company. I now need to expand these regular expressions.
Samples:
a = 0-3
b = Null, 0, 1
Expression: Meaning
1:5: 1,2,3,4,5
1a: 10, 11, 12, 13
1b: 1, 10, 11
1[2,3]ab: 120, 1200, 1201, ....
It get's even more inetersting because there is a possibility of 1[2,3]a.ab
I have created two base queries to aid me in my quest. I am using the SQL MODEL clause to solve this problem. I pretty confident that I should be able to convert evrything into a range and the use one of the MODEL clause listed below.
My only confusion is how do I INCREMENT dynamically. The INCREMENT seems to be a constant in both a FOR and ITERATE statement. I need to figure a way to increment with .01, .1, etc.
Any help will be greatly appreciated.

               This reads ITERATE 100000 times or UNTIL the ITERATION_NUMBER = max_key[0] - min_key[0]
               which would be 4 for '1:5', but since the ITERATION_NUMBER starts at 0, whatever follows
               is repaeted 5 times.
Line 29:     m_1[ITERATION_NUMBER] = min_key[0] + ITERATION_NUMBER
               m_1[ITERATION_NUMBER] means m_1[Value of Dimension KEY].
               Thus for each row of KEY the m_1 is min_key[0] + ITERATION_NUMBER.

Of course, you can accomplish the same thing without MODEL using an Integer Series Generator like this.
create table t ( min_val number, max_val number, increment_size number );
insert into t values ( 2, 3, 0.1 );
insert into t values ( 1.02, 1.08, 0.02 );
commit;
create table integer_table as
select rownum - 1 as n from all_objects where rownum <= 100 ;
select
min_val ,
increment_size ,
min_val + (increment_size * n) as val
from t, integer_table
where
n between 0 and ((max_val - min_val)/increment_size)
order by 3
   MIN_VAL INCREMENT_SIZE        VAL
      1.02            .02       1.02
      1.02            .02       1.04

How can I set a variable number of values in a SQL IN clause?

Hi,
How can I set a variable number of values in a SQL IN clause without having to change the text of the SQL statement each time?
I read the link http://radio.weblogs.com/0118231/2003/06/18.html. as steve wrote.
SELECT *
FROM EMP
WHERE ENAME IN (?)
But we need the steps not to create type in the system and would there be any other solution if we would like to use variable number of values in a SQL IN clause ?
We are using JDeveloper 10.1.3.2 with Oracle Database 10.1.3.2
Thanks
Raj

Hi,
can you please explain why the solution from steve is not the right solution for you.

&param lexical variable in SELECT clause

Is there a way to get Oracle*Reports to accept a lexical variable in the SELECT clause? The example is:
SELECT
table.column1,
table.column2,
&PARAM as column3
FROM
table
I am already using lexical variables in the WHERE clause, but getting one to work in the SELECT clause has thus far failed.
The SQL is accepted if :PARAM is used in place of &PARAM, but I am unable to actually vary the selected column this way.
The bind variable PARAM has the following code behind it in a BeforeReport trigger:
IF :ANOTHER_PARAM := 'ALL' THEN
:PARAM = 'ALL'
ELSE
:PARAM = 'table.column3'
When using :PARAM in the SELECT clause, the literals 'table.column3' are returned, not the contents of table.column3.

Sorry for the wasted bandwidth. I found a solution. Here it is:
SELECT
table.column1,
table.column2,
CASE :P_USER
WHEN 'ALL' THEN 'ALL'
ELSE table.column3
END as column3

Merge can't accept a variable in the select clause?

Using a select clause in the column formula in an Analysis

Hi all,
Is there a function or syntax that I can use to simulate a "SELECT" clause in the column formula of an Analysis? What I am trying to achieve is displaying a measure from a specific fact record into the current record. For example, if the current record displays "Region","position", and "salary", I would like to add an additional column called "compared to" in which I can display the "salary" measure from another specific fact record whose attributes I know.
Is there a function/statement that I can use to achieve this?
Thanks

Hi,
U can't do it in Edit formula column..it's possible below one
Add SQL filter in that column then follow blow steps
Convert this filter to SQL
i.e : add more option to sql here u can write SQL query in that column

How to remove column name in select clause

Hello Guys,
I just want to remove a column name in select clause. Because, I don't want to write all column names. I hope I express myself.
In other words, I want the following.
Select   * - unwanted_column from table;
instead of this
Select col1, col2, col3, col4, ........ col 10000 from table;

Hi,
Sorry, there's nothing in SQL that means "all columns *except* ...". As the others have said, the only way to get those results in SQL is to list all the columns you do want.
Your front end may have some feature that allows you to hide a specific column. For example, in SQL*Plus, you can use <tt> COLUMN ... NOPRINT </tt> , like this:
COLUMN      dname     NOPRINT
SELECT       *
FROM       scott.dept
ORDER BY dname
;Output:
`   DEPTNO LOC
        10 NEW YORK
        40 BOSTON
        20 DALLAS
        30 CHICAGOThere is a column called dname in the scott.dept table; the query above actually uses it. But, because of the COLUMN command, SQL*Plus won't display that column.

Maximum no. of columns allowed in SELECT clause - Urgent please

Hi,
I am constructing SQL query dynamically in a stored proc. based on user inputs. I am getting following error when I have around 400 columns in my SELECT clause. FROM, WHERE, GROUP BY clauses are same eventhough I have 30 columns and I don't have any problems here. Can anyone please let me know what is maximum no. of columns allowed in a query. I am working on Oracle 9i Release2.
Thanks in advance.

ORA-01467 sort key too longIt's not the SELECT clause that causes this, it's most likely the GROUP BY clause. Basically, the columns in the GROUP BY clause have to fit comfortably within a single database block. Does that sound like it might be a problem with your query?

Problems with query with more than 20 values in the select clause

I have a region based on a function returning a SQL query. It needs to have more than 20 values in the select clause. When I run the page I get a no data found error in the region. I managed to reproduce this behavior with just the following as the select returned by the function:

Hello Raju,
I will email you the connection settings when I return to the office.
One thing I should have mentioned: The sql string is returned from a package in the db, so the query region text I originally posted isn't quite correct.
it is something like:

return my_pkg.my_fnc;
end;
the stored package is nothing more than:
package my_pks is
funtion my_fnc(i_test_param in varchar2) is
begin
return 'select 1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20, 21 from dual';
end;
end;
Sorry for the inaccurate info in the first post, but I am away from the server in question right now.
