SQL statement with union clause

Hi,
I have a scenario where i need to generate a sql statement with UNION .
Eg:
SELECT B.YY_ID,
FROM XXXX.YY B
WHERE (B.YY_TY= 'as')
UNION
SELECT B.YY_ID
FROM XXXX.YY_ALT_NAME A, XXXX.YY B
WHERE (A.YY_TY= 'zx'
AND (B.YY_ID=A.YY_ID)"
I tried ns1:table1() union ns3:table2() in XQuery.
But it is pushdown as 2 seperate sqls.
Is it possible to create XQuery that pushdown as SINGLE SQL statement with union clause ?
Thanks

No. See 3.1.1.5 in the document I referenced in your previous post.

SQL error with LIKE clause in statement

Can anyone explain how an SQL statement with a LIKE clause is executed properly?
Seems like it ought to be cut and dried, no pun intended!
When I run the following and set the requestor name = ?, and correctly type in the entire name, a result set (albeit abbreviated) will return.
But if I try to set the request param to LIKE I get an error of some kind, either invalid cursor state or NullPointer exception.
Here's my code.
Statement selstmt = connection.createStatement();
String preparedQuery = "SELECT DISTINCT AID, ACTIVE, REQUESTOR_NAME,REQUESTOR_EMAIL" +
" FROM CHANGE_CONTROL_USER, CHANGE_CONTROL_ADMIN " +
" WHERE REQUESTOR_NAME LIKE '%?%';";
String reqName = request.getParameter("requestor_name");
PreparedStatement prepstmt = connection.prepareStatement(preparedQuery);
prepstmt.setString(1, reqName);
ResultSet rslts = prepstmt.executeQuery();
rslts.next();
int aidn = rslts.getInt(1);
int actbox = rslts.getInt(2);
String reqname = rslts.getString(3);
String reqemails = rslts.getString(4);It's also returning only 1 record for some reason, as I have the following:
<% while (rslts.next()) { %>
<tr class="style17">
    <td><%=reqname%></td>
<td><%=reqemails%></td>
   <td><%=actbox %></td>
    <td><%=aidn %></td>
</tr>
<%
rslts.close();
selstmt.close();
%>If I use
" FROM CHANGE_CONTROL_USER, CHANGE_CONTROL_ADMIN " +
" WHERE REQUESTOR_NAME = ?;";it will actually spit out the name and corresponding email properly, albeit just one record like I said.
Is there some kind of escape sequence I should be using that I'm not?
And why just the one record?
Any help or direction is appreciated!
Thanks.

I have working code for LIKE in PreparedStatement, and its equivalent in your case is something like this:Statement selstmt = connection.createStatement();
String preparedQuery = "SELECT DISTINCT AID, ACTIVE, REQUESTOR_NAME,REQUESTOR_EMAIL" +
" FROM CHANGE_CONTROL_USER, CHANGE_CONTROL_ADMIN " +
" WHERE REQUESTOR_NAME LIKE ?";
String reqName = request.getParameter("requestor_name");
PreparedStatement prepstmt = connection.prepareStatement(preparedQuery);
prepstmt.setString(1, "%" + reqName.trim() + "%");
ResultSet rslts = prepstmt.executeQuery();
rslts.next();
int aidn = rslts.getInt(1);
int actbox = rslts.getInt(2);
String reqname = rslts.getString(3);
String reqemails = rslts.getString(4);

Select query with UNION clause in database adapter

Friends,
I have got a SQL query with two UNION clause withing it. like
select a,b,c
from a
union
select a,b,c
from b
The schema generated is like below in sequence
<element>a</element>
<element>b</element>
<element>c</element>
<element>a</element>
<element>b</element>
<element>c</element>
So, the columns from different select queries joined with UNION clause are all appeared in schema instead of the distinct columns.
Is there any way around to solve this issue ? or will need to with DB function/procedure.

I think I know what you are saying but your example doesn't make sense, your SQL should produce something like
I had to change a, b, c with elementA, elementB, elementC as a and b are reserved html tags.
<elementA>DateA</elementA>
<elementB>DataB</elementB>
<elementC>DataC</elementC>
...What is the result of the query when you run it in SQLPlus? Is it what you expect?
cheers

Pl/sql statement with output in reports

Hello,
I am quite new to reports and pl/sql, i have built a pl/sql statement with some loops that works fine when running it in sqlplus.
I would really like to have this running in reports with the variables (v_year, v_month and v_sumvalue) in a table/record in the data view, so i can use them just like any ordinary fields in a table for example in a diagram.
I have tried to create a package spec, setting up a record with the variables as fields. And then a pl/sql function with the following sql (which was a bit modified to work in the pl/sql function). Everything seemed to work since the pl/sql table/record was there with the variables as fields in it, but it never returned anything... just fatal error.
Here is the original pl/sql statement which is working in sqlplus, any help/directions in how to get this working so i can use the variables like fileds in a regular table would be fantastic:
DECLARE
   v_year number(4);
   v_month number(2);
   v_sumvalue number(9,3);
   v_sta varchar2(10);
   v_end varchar2(10);
   v_stopmonth number(2);
BEGIN
   --## Get last 5 years ##--
   select
      to_char(add_months(sysdate,-60),'YYYY'),
      to_char(sysdate,'MM')
      into v_year, v_stopmonth
   from
      dual;
   --dbms_output.put_line(v_year);
   --## Loop 5 years ##--
   for i in 1..5 loop
      v_year := v_year + 1;
      --dbms_output.put_line(v_year);
      --## Loop 12 times (months) ##--
      for k in 0..11 loop
         v_month := k +1;
         --dbms_output.put_line(v_year ||'-'|| v_month);
         select
            sum(nvl(p.value,0)) / 3,
            last_day(add_months(to_date(v_year ||'-'|| v_month ||'-01','YYYY-MM-DD'),-3))+1,
            last_day(to_date(v_year ||'-'|| v_month ||'-01','YYYY-MM-DD'))
            into v_sumvalue, v_sta, v_end
         from
            project p
         where
            p.country_code = 'SWE'
         and
            p.project_type_code = 'P'
         and
            p.start_date between last_day(add_months(to_date(v_year ||'-'|| v_month ||'-01','YYYY-MM-DD'),-3))+1 and last_day(to_date(v_year ||'-'|| v_month ||'-01','YYYY-MM-DD'))
         and
            p.q_category_code between 1000 and 1299
         and
            p.geography_code between 2100 and 2199;
         dbms_output.put_line(v_year ||'-'|| v_month ||' '|| v_sumvalue);
         --dbms_output.put_line(v_year ||'-'|| v_month ||' '|| v_sumvalue ||' '|| v_sta ||' '|| v_end);
      --## Stop monthloop ##--
      end loop;
   --## Stop yearloop ##-
   end loop;
END;Output:

Yes this is possible. use the below reference code for this.
data: g_tablename type w_tabname,
gv_dref TYPE REF TO data.
FIELD-SYMBOLS: <g_itab> TYPE STANDARD TABLE.
gv_tabname = p_tablename (take table name form selection screen or as per ur requirement)
CREATE DATA gv_dref TYPE TABLE OF (g_tabname).
ASSIGN gv_dref->* TO <g_itab>.
now use the below select query to fetch the data
SELECT * FROM (gv_tabname) INTO TABLE <g_itab>.
Hope this will help

SQL-Statement with OO4O

Hello together,
I post this Question here in

Hi,
What can you do/change?I must ask next week my boss when he is back,
what kind of changes I can do.
Can you add a PL/SQL call to DBMS_APPLICATION_INFO into application?my boss must give me the permission to do a call to DBMS_APPLICATION_INFO.
A way to identify the source of the badly behaving code is required; whether that be within the DB or external of it.I think so too.
So please wait, until I have talk with my boss, than I will give you the answer you want. Sorry.
Any other ideas, what I can do without call/changes on the database to find the problem?
Best Regards
Andy

ABAP/4 Open SQL statement with WHERE ... LIKE and pattern too long

Dear All,
I am getting an error "ABAP/4 Open SQL statement with WHERE ... LIKE and pattern too long" while executing the following statement:
CLEAR LS_RANGE.
LS_RANGE-SIGN     = 'I'
+LS_RANGE-OPTION     = 'CP'     +
LS_RANGE-LOW     = 'S_ADMI_FCD'
LS_RANGE-HIGH     = 'S_ADMI_FCD'
COLLECT LS_RANGE INTO LT_RANGE.
SELECT *
           FROM UST12
           INTO CORRESPONDING FIELDS OF TABLE LT_OBJECT_VALUES
           WHERE FIELD IN LT_RANGE
           AND AKTPS   = 'A'.
For options like BT(Between), EQ(Equal) in range table, this above query is executing without dump. But for option CP, it simply dumps & in dump what i found is, it is concatenating the value in low & high.
Does anyone have any idea regarding open sql using range tables.
Thanks,
Bhupinder

Hi,
I commented as follows:
If LS_RANGE-HIGH is empty, you can use EQ, NE, GT, LE, LT,CP, and NP. These operators are the same as those that are used for logical expressions. Yet operators CP and NP do not have the full functional scope they have in normal logical expressions. They are only allowed if wildcards ( '*' or '+' ) are used in the input fields. If wildcards are entered on the selection screen, the system automatically uses the operator CP.
If LS_RANGE-HIGH is filled, you can use BT (BeTween) and NB (Not Between). These operators correspond to BETWEEN and NOT BETWEEN that you use when you check if a field belongs to a range. You cannot use wildcard characters.
You can try:
CLEAR LS_RANGE.
LS_RANGE-SIGN = 'I'.
+LS_RANGE-OPTION = 'CP' +
LS_RANGE-LOW = 'S_ADMI_FCD'.
LS_RANGE-HIGH = 'S_ADMI_FCD'.
FIND '*' IN LS_RANGE.
IF sy-subrc = 0.
LS_RANGE-OPTION = 'CP'.
ELSE.
LS_RANGE-OPTION = 'EQ'.
ENDIF.
COLLECT LS_RANGE INTO LT_RANGE.
SELECT *
FROM UST12
INTO CORRESPONDING FIELDS OF TABLE LT_OBJECT_VALUES
WHERE FIELD IN LT_RANGE
AND AKTPS = 'A'.
If you use wildcards the LS_RANGE length should not exceed 10 characters.
Hope this information is help to you.

Display the sql statement with arguments with ojdbc14_g.jar

Hi,
I'd like to display the sql statements with ojdbc14_g.jar.
So I've followed the documentation and set an OracleLog.properties file which is linked to my java program.
The problem is the trace generated is huge and I only need the SQL requests wich are made with the arguments but I don't know how to configure that.
Have you got a sample file which handle that ?
I've tried that :
oracle.jdbc.handlers=java.util.logging.ConsoleHandler
java.util.logging.ConsoleHandler.level=CONFIG
java.util.logging.ConsoleHandler.formatter=java.util.logging.SimpleFormatter
oracle.level=INFO
oracle.jdbc.driver.level=OFF
oracle.jdbc.driver.OraclePreparedStatement.level=OFF
oracle.jdbc.pool.level=OFF
oracle.jdbc.util.level=OFF
oracle.sql.level=INFO
But that doesn't display only the SQL and args :(
Regards.

The fact is the statement are made by ejb entities on JBoss so I don't have a way to make specific logger to display the sql order. The only thing I can do is to set the log4j org.jboss.ejb.plugins.cmp to a trace level in order to see the sql order but without the arguments.
I tried those traces however I see stuff like that without any SQL orders :

Hosting company does not support SQL query with OUTFILE clause

From my mysql database, I want to allow the user to run a query and produce a csv / text file of our membership database. Unfortunately, I just found out my hosting company does not support the SQL query with OUTFILE clause for MySQL database.
Are there any other options available to produce a file besides me running the query in phpadmin and making the file available to users.
Thanks. George

Maybe this external Export Mysql data to CSV - PHP tutorial will be of help

How to Run SQL Tuning Advisor on the SQL statement with SQL_ID?

Can you give the steps to run the SQL tuning advisor on the SQL statement with SQL_ID?
Database version: 10g Release 2

Hi,
You can use either the automatic SQL tuning features that are accessible from Enterprise Manager Database Console on the "Advisor Central" page or trough SQL*PLUS using the DBMS_SQLTUNE pakage:
-- creating the tuning task
set serveroutput on
declare
l_sql_tune_task_id varchar2(100);
begin
l_sql_tune_task_id := dbms_sqltune.create_tuning_task (
                          sql_id      => '<your_sql_id>',
                          scope       => dbms_sqltune.scope_comprehensive,
                          time_limit => 60,
                          task_name   => '<your_tuning_task_name>',
                          description => 'tuning task for statement your_sql_id.');
dbms_output.put_line('l_sql_tune_task_id: ' || l_sql_tune_task_id);
end;
-- executing the tuning task
exec dbms_sqltune.execute_tuning_task(task_name => '<your_tuning_task_name>');
-- displaying the recommendations
set long 100000;
set longchunksize 1000
set pagesize 10000
set linesize 100
select dbms_sqltune.report_tuning_task('<your_tuning_task_name>') as recommendations from dual;For more information, take a look at link provided by Jaffy.

SQL statement with Function returns slow in Interactive Report

I have an Interactive Report that returns well but when I add in a function call in the where clause that does nothing but return a hard coded string of primary keys and is compared to a table's primary key with a like operator the performance tanks. Here is the example:
get_school2_section(Y.pk_id,M.pk_id,I.section,:P577_SECTION_SHUTTLE) LIKE '%:' || I.pk_id || ':%'
I have the values hard coded in the return of the function. There are no cursors run in the function, there is no processing done in the function. It only declares a variable. Sets the variable, and returns that variable back to the SQL statement.
I can hard code the where clause value to look like this:
':90D8D830A877CCFFE040010A347D1A50:8ED0BBFDEAACC629E040010A347D6471:9800B8FDBD22B761E040010A347D0D9A:' LIKE '%:' || I.pk_id || ':%'
This returns fast. When I add in the function call which returns the same hard coded values, the page goes from returning in 1 to 2 seconds to 45 or more seconds.
Why does adding a simple function call into the where clause cause such a deterioration in performance.

So you are telling me that the where clause with a function call will NOT run the function on every row? Please explain that to me further?
if you have code that is the following:
select a,b,c from a_table where a > 2 and b < 3 and function_call(c) > 0You are telling me that Oracle will NOT call that function on EVERY row it tries to process in the select?
Thank you,

02 ram
03 kamal
04 sathish
i will give the empname values like 'siva,kamal,roshan,sathish' and empno >03,but in the table roshan name is not there.I need the below mentioned o/p
example qry: select empno,empname from test_tab where empname in('siva','kamal','roshan','sathish') and empno>03;
my o/p should be like this,
empname empno
sathish 04
roshan ''
But the empname 'roshan' is not there in table.I need the empname as 'roshan' and empno is null value in a single select query or subquery or any sql statements.
Please help me the resolve this issue.
Thanks

Hi,
Do you want this?
with data as
(select 1 EMPNO, 'siva' as empname from DUAL union all
select 2 EMPNO, 'ram' from DUAL union all
select 3 EMPNO, 'kamal' from DUAL union all
select 4 EMPNO, 'sathish' from DUAL union all
select null EMPNO, 'roshan' from DUAL )
select * from data
where EMPNAME in ('siva','kamal','roshan','sathish')
and nvl2(empno,empno,4) > 3

Order by decode statement with Union all

Hi
I use Database Version: Oracle 9.2.0.1.0
OCI version 9.2
I try to use order by decode while i have a select base on union and I get en error:
ORA-01785: ORDER BY item must be the number of a SELECT-list expression
Here is my code:
select catalog_type, catalog_id, item_id, item_name
from items_catalog
union all
select catalog_type, catalog_id, organisation_unit_id, organisation_unit_name
from units_catalog
order by decode(catalog_type, 1, item_id, organisation_unit_id)
If I use the decode on a select statement without union, it works.
What I have to do in order to make it work on union all select?
Tnx

Hi,
Here's a slightly different way:
COLUMN     sort_key   NOPRINT
VARIABLE     catalog_type_wanted     VARCHAR2 (5)
EXEC         :catalog_type_wanted := '4';
SELECT       catalog_id, item_id, item_name
,       CASE
           WHEN :catalog_type_wanted = '1' THEN '1'
                                           ELSE '2'
       END || item_id          AS sort_key
FROM       items_catalog
      UNION ALL
SELECT    catalog_id, organisation_unit_id, organisation_unit_name
,       CASE
           WHEN :catalog_type_wanted = '1' THEN '2'
                                           ELSE '1'
       END || organisation_unit_name     AS sort_key
FROM       units_catalog
ORDER BY sort_key
;This way guarantees that (for example) 'SHOP50' comes before 'SHOP58', whether or not they are in the first half of the output or the second half.
Notice that this uses the SQL*Plus COLUMN ... NOPRINT command to hide the sort_key column.
If you're not using SQL*Plus, then whatever front end you are using may have a similar feature.
If not, then you can do the UNION in a sub-query, as Daniel did, but do the ORDER BY in the main query (only).
