Using a varchar field to select statement

Hi all
I have a single row and single column table
T(command varchar2(4000))
and the row is
sno,name
And I have another table T1(sno number,name varchar)
Now can any body tell how can i use command column in table T to query T1 to get sno,name from T1
I am looking for a select statement like this
select (select command from T) from T1;
but it is printing out the data in T i mean sno, name
This is a copy of thread Selecting output of a select statement
but explained more clearly
Thanks,
ganesh.

I don't know why your tables are designed like this but what I think you want to do is join T1 with the data in T.
select sno, name from T1
where sno in (select substr(command,0,instr(command,',')-1) from T)
and name in (select substr(command,instr(command,',')+1) from T);
substr returns a string up to a position
instr returns the position of a string
and the other post you refer to as about as confusing as your one.

Using pop-up value in select statement

Hello.
I want to select a value from a pop-up box and then use that value in a select statement for another pop-up. Is that possible?
The first pop-up is P39_PIIN_CALL but it is not recognized in the second pop-up when I use it in the select statemnt... select * from table where PIIN = :P39_PIIN_CALL. I get nothing back because it has no idea what :P39_PIIN_CALL is. I'm desperate and on a timeline.
Thanks,
Mark E

Hi,
After fetching the value from first popup the page should submit so that the value is availble to the second popup..
Edit the first popup.. and in HTML Form Element Attributes and enter onchange="doSubmit('MyRequest')"

Limitations in using a function within a select statement

I have a function which retrieves various data elements from the
database and formats it accordingly. The data (varchar2)
returned could be in excess of 2,000 characters length.
I need to use the returned data as part of a view. I am able to
use the function in a "select" statement, but when I use it with
returned data in excess of 2,000 chars, I get the following
error:
ORA-06502: PL/SQL: numeric or value error
This error is occurring whenever the returned data is in excess
of 2,000 characters.
Is there an alternative method to what I am proposing, I have
tried alternative data types but if I am able to use it in a
"select" statement, I get the above error when the returned
length exceeds 2,000 chars.
Thanks
Peter

are u using oracle 7. varchar2 limit in 8 is 4000.

Use of cursors insted of select statements

could any one please explain what is the advantage of using cursors instead of simple select statements
thanks
siby

A benefit to using an explicit cursor rather than a select statement, is for the NO_DATA_FOUND exception. Its kind of like a free IF statment. IF no data is found, then stop.
if you write a select statement, and no data is returned, you SHOULD code for the NO_DATA_FOUND exception. Often people say, "i'll ALWAYS get a row returned". but you should always cover your code "just in case". so you must code an exception...
declare
v_var varchar2(1);
procedure do_something(p_parm varchar2) is
begin
null;
end do_something;
procedure log_error is
begin
null;
end log_error;
begin <<main>>
do_something('x');
begin <<selectblock>>
select dummy
into v_var
from dual
where dummy = 'a';
do_something(v_var);
exception
when no_data_found then
log_error;
end selectblock;
do_something (v_var||'abc');
end main;
if you use an explicit cursor instead, you don't need to code for the NO_DATA_FOUND. If an explicit cursor opens and finds no rows, there are simply no rows. of course, you don't need a loop if you expect only 1 row returned under normal circumstances.
BTW, don' forget that SQL%ROWCOUNT and your_cursor%ROWCOUNT are not initialized. There is a null, until a row is successfully fetched. therefore if no rows are returned at all, %ROWCOUNT is NULL.
declare
v_var varchar2(1);
cursor my_cur is
select dummy
from dual
where dummy = 'a';
procedure do_something(p_parm varchar2) is
begin
null;
end do_something;
procedure log_error is
begin
null;
end log_error;
begin << main>>
for cur_rec in my_cur loop
dbms_output.put_line('inside');
begin <<loop_block>>
if nvl(my_cur%rowcount,0) > 1 then
do_something(cur_rec.dummy);
else
log_error;
end if;
end loop_block;
end loop;
end main;

Using a varchar field as number on ui

Hello
In one of the requirements we got to use a varchar field in db to store as number in UI. The user may specify + or - in the begining and it can be number up to 2 decimal places.
So, how to achieve this?
We are using jdev 11.1.1.6.2

may be have a transient field with number datatype and use af:convertNumber with minFractionDigits and maxFractionDigits to 2. it would take - not sure about + sign (might remove automatically). convert this as string and try saving it with your actual field.

Can we use is null in our select statement in ABAP program

Dynamic fields in select statement

Hi all,
   In selection screen we are having period as select option.The values for period are 01 to 16. Based on
      the values entered in selection screen for period we need to select HSLXX from FAGLFLEXT.
   For example if we enter 01 to 03 in selection screen then we need to select HSL01 HSL02 HSL03
       from FAGLFLEXT.
Like this we need to select fields dynamically in select statement. Can any one tell me how to restrict fields dynamically.
Regards,
Swetha

hi Swetha,
the third select statemnet will work for you..
try this..
_Dynamic where clause in select query.._
* With a variable, result: AND rbusa = '5145'
concatenate 'AND rbusa = ' '''' i_tab-zgsber ''''
append where_clause to where_tab.
* Select
select * from zcostfreq
     where (where_tab).
endselect.
_Using a dynamic table name_
parameters:
p_tab type tabname.
start-of-selection.
select count(*) from (p_tab) into l_count.
_Dynamic retrieval and writing of data_
FIELD-SYMBOLS:
<row>         TYPE ANY,
<component>   TYPE ANY.
PARAMETERS:
p_tab TYPE tabname.
CREATE DATA dataref TYPE (p_tab).
* The variable dataref cannot be accessed directly, so a field symbol is
* used
ASSIGN dataref->* TO <row>.
SELECT *
    FROM (p_tab) UP TO 10 ROWS
    INTO <row>.
    NEW-LINE.
    DO.

Where condition with optional fields in select statement

Hi,
In a function module I have to fetch data based on 7 fields out of which 6 are optional.
If we won't enter values for optional fields it will take default values as zeroes .
So this is not fetching data. But for some fields some values has zero values.
How to solve this condition?
Regards,
maha.

Hi,
For those import parameters for which its mentioned as optional, use like condition in the where clause of select statement in the function module.
try like this,
concatenate pfield2 '%' into pfield2.
concatenate pfield3 '%' into pfield3.
concatenate pfield4 '%' into pfield4.
concatenate pfield5 '%' into pfield5.
concatenate pfield6 '%' into pfield6.
concatenate pfield7 '%' into pfield7.
select *
from db table
into itab
where field1 = pfield1 and
           field2 like pfield2 and
           field3 like pfield3 and
           field7 like pfield7.
Now even if the optional fields are blank, data will be selected

How to use bind variable in this select statement

Hi,
I have created this procedure where table name and fieldname is variable as they vary, therefore i passed them as parameter. This procedure will trim leading (.) if first five char is '.THE''. The procedure performs the required task. I want to make select statement with bind variable is there any possibility to use a bind variable in this select statement.
the procedure is given below:
create or replace procedure test(tablename in varchar2, fieldname IN varchar2)
authid current_user
is
type poicurtype is ref cursor;
poi_cur poicurtype;
sqlst varchar2(250);
THEVALUE NUMBER;
begin
     sqlst:='SELECT EMPNO FROM '||TABLENAME||' WHERE SUBSTR('||FIELDNAME||',1,5)=''.THE ''';
     DBMS_OUTPUT.PUT_LINE(SQLST);
OPEN POI_CUR FOR SQLST ;
LOOP
     FETCH POI_CUR INTO THEVALUE;
          EXIT WHEN POI_CUR%NOTFOUND;
          DBMS_OUTPUT.PUT_LINE(THEVALUE);
          SQLST:='UPDATE '||TABLENAME|| ' SET '||FIELDNAME||'=LTRIM('||FIELDNAME||',''.'')';
          SQLST:=SQLST|| ' WHERE EMPNO=:X';
          DBMS_OUTPUT.PUT_LINE(SQLST);
               EXECUTE IMMEDIATE SQLST USING THEVALUE;
END LOOP;
COMMIT;
END TEST;
Best Regards,

So you want to amend each row individually? Is there some reason you're trying to make this procedure run as slow as possible?
create or replace procedure test (tablename in varchar2, fieldname in varchar2)
authid current_user
is
   sqlst      varchar2 (250);
   thevalue   number := 1234;
begin
   sqlst := 'update ' || tablename || ' set ' || fieldname || '= ltrim(' || fieldname || ',''.'') where substr(' || fieldname
      || ',1,5) = ''.THE ''';
   dbms_output.put_line (sqlst);
   execute immediate sqlst;
end test;will update every row that satisfies the criteria in a single statement. If there are 10 rows that start with '.THE ' then it will update 10 rows.

How to use variables in an sql select statement.

Hi, I have seen examples using the update, but nothing using a select statement.
I have four variables I am getting from drop down menus in my JSP I set the user selected items to strings.
How would I create the select statement like this:
.String XName = request.getParameter("UserInputX");
rsInResult = stmtInResult.executeQuery("SELECT ColumxX FROM TableZ WHERE ColumnX = XName")Obviously it tries to read "XName" as a column and of course can't find it, how would I set it up to have it see the Value of XName and not the literal XName.

read this:
rsInResult = stmtInResult.executeQuery("SELECT ColumxX FROM TableZ WHERE ColumnX = '"+XName+"')
{code}
better way is PreparedStatement:
{code}
     // example code to change password to an user in the USERS table
     String newPWD = "my password";
     String user = "luxjava";
     PreparedStatement prepStat;
     String updatePWD = "UPDATE LOGISTIC.USERS "+
                              "SET logistic.users.password = ? "+
                              "WHERE logistic.users.username = ?";
     prepStat = ql.conDb.prepareStatement(updatePWD);
     prepStat.setString(1, newPwd);
     prepStat.setString(2, user);
     int zeroNotFound = prepStat.executeUpdate();
     if (zeroNotFound==0)
          ql.conDb.rollback();
          prepStat.close();
     else
          ql.conDb.commit();
          prepStat.close();
{code}
... use the SQLException to capture errors

Problems with Hints in abap code to use an index in a Select statement

select *
from (select myrows.*, rownum rn
          from (select acc as account,

                 where emp_id = ? as my site from myview where ert_id=? and chek=?apparently the syntax is not correct and by that you are missing some comma in your column, ? question mark symbol will not be recognize, and some ')' closed parenthesis.
are you using a report builder that you want to use a placeholder column?

Determine Length of Field in Select Statement

Hi Experts!
My officemate has this little problem regarding selection of data based on a certain condition...
Here is the situation:
For Example...
In table KNA1....
KUNNR       NAME1         Length of Data in Name1
000001        AA                2
000002        AB                2
000003        ABCD           4
000004        ABCDE         5
She only wants to get the records that has the length of 2 in KNA1-NAME1,
i.e., 'AA' and 'AB' without having to put it in the internal table then make a loop and update the table using the strlen() condition....
Experts, is this possible? Knowing the length of the data in the select statement? She wants this alternative because it is faster rather than having to loop in internal tables and check if this data has the length of 2 or 3 or 4 and so on....
Can you please help me out with this one? Thanks in advance!
<b></b>

Hi
If the lenghtn is 6 characters and if you want to fetch only first 2 characters.
you can use offset
fetch data from internal table and take variable
v_var1 = itab-name1+0(2).
you get only first 2 characters....
if you want last 2 characters itab-name1+4(2).
Thanks

Usgent: using jsp date in sql select statement

i have something like this:
String day;
String month;
String year;
select * from event where date = xxx
where xxx is supposed to be obtained from the strings (day, month, year) and changed into a format that can be compared to in the select statement.
what should xxx be?
thks as lot cos i ahe been figuring out for very long.

Use PreparedStatement and SimpleDateFormat:
String year = "2002";
String month = "9";
String day = "12";
String sDate = day + "/" + month + "/" + year;
SimpleDateFormat df = new SimpleDateFormat("M/d/yyyy");
Date dDate = df.parse(sDate);
Connection con = DriverManager.getConnection(user, pw);
PreparedStatement ps = con.prepareStatement("SELECT * FROM event WHERE date = ?");
ps.setDate(1, dDate);
ResultSet rs = ps.executeQuery();
while (rs.next()) {
rs.close();
ps.close();
con.close();

Restrict number of characters in table field for select statement.

SELECT * FROM table
                WHERE column1 = z-column.
The field column1 is of type char and size 20
The field z-column is of type char size 10.
how do we perform this select?
Anyone can guide me?

Hello,
In your OP did you mention this? Please be specific when you post the next time.
Can you please post your code?
I think you have to try a work around:
DATA:
RS_STOCKID TYPE SELOPT,
RT_STOCKID TYPE STANDARD TABLE OF SELOPT.
LOOP AT GT_ZB1PUT_STOCKTMP.
RS_STOCKID-SIGN = 'I'.
RS_STOCKID-OPTION = 'EQ'.
RS_STOCKID-LOW = GT_ZB1PUT_STOCKTMP-STOCKID.
APPEND RS_STOCKID TO RT_STOCKID.
CLEAR RS_STOCKID.
ENDLOOP.
You can use this RANGE table to SELECT data from the table.
SELECT * FROM zb1xxt_param
            FOR ALL ENTRIES IN gt_zb1put_stocktmp[]
            WHERE zzcode    = 'DEV036'
            AND   zzdomain = 'SD'
            AND   zzdata    = 'INBOUND'
            AND   zzinput1 = 'STOCKID'
            AND   zzinput2 IN RT_STOCKID. "Use RT_STOCKID for SELECT'ing data
