  As Juliet was mentioned in the first SQL that you generate from the ENAME list that you must pass in the IN clause when executing. But in the second SQL, it passed as a static value. So first SQL must do more work. So you see a different execution plan.

  But this is a work around to get what you are looking for. But I can't say it's a foolproof method. But anyway here you go.

• Using arrary associative as parameter and passing then to the place where the clause of the select statement

  Hello

  I have this scenario where I have to pass multiple values to a parameter of a procedure of monkey and then collect in another variable (the lines can be multiple).

  The parameter must be used in the where clause of the statement select here I create a sample table for the problem.

  Create table test_tab (number of trans_id, cmts varchar2 (50));

  insert into test_tab values (568890112115, ' wnlb-CMTS-11-04' ");

  insert into test_tab values (568890112115, ' wnlb-CMTS-11-04' ");

  insert into test_tab values (568890112115, ' wnlb-CMTS-11-01' ");

  insert into test_tab values (568890112115, ' wnlb-CMTS-11-01' ");

  insert into test_tab values (568890112115, ' wnlb-CMTS-11-01' ");

  insert into test_tab values (568890112115, ' wnlb-CMTS-12-02' ");

  insert into test_tab values (568890112115, ' wnlb-CMTS-12-02' ");

  This is so all cmts have same trans_id but different name

  This query gives the result as -

  Select the cmts, count (1)

  of test_tab

  where cmts ("wnlb-cmts-11-04','wnlb-cmts-11-01", "wnlb-CMTS-11-02'")

  and trans_id = 568890112115

  Cmts group;

  COUNTY OF CMTS

  WNLB-CMTS-11-04 2

  3 WNLB-CMTS-11-01

  Now, I want to use this query in a PLSQL block like where I can spend the CMTS collection and trans_id as a scalar variable and once again an OUTPUT parameter that holds the result of the query.

  I use OUT parameter because it will be called to the JAVA program.

  Here, I write a PACKAGE for it but it gives me compilation error!

  create or replace package CMTS_SUCCESS_FAILED_API

• Using the conditional to determine the Select statement

  I don't know if anyone knows if I can do that, but I try to use a factor based on a value on what query to run...
  
  Something like:

  DECODE('INBOUND', 
       'INBOUND', SELECT 'I' FROM DUAL, 
       'OUTBOUND', SELECT 'O' FROM DUAL, 
       'BOTH', SELECT 'B' FROM DUAL);

  OR

                  WHEN '<~S~>' = 'OUTBOUND' THEN SELECT 'OUTBOUND' FROM DUAL 
                  ELSE SELECT 'BOTH' FROM DUAL 
             END 
         ) AllValues

  Is it still possible?

  Scalar subqueries should appear in square brackets, for example

  select case dummy
            when 'X' then (select 'First example' from dual)
            when 'Y' then (select 'Second example' from dual)
         end as demo
  from dual;
  

  or if you prefer the old syntax DECODE,

  select decode(dummy,
                'X', (select 'First example' from dual),
                'Y', (select 'Second example' from dual)

  My research assessing the order of the select statement is below.

   4 connect by
   5 where (filter of rows)
   6 group by

  My question is Where clause Pivot and UnPivot clause ?
  
  http://download.Oracle.com/docs/CD/E16338_01/server.112/e10592/statements_10002.htm

  Well the pivot is applied to a single table or an inline or a view - so it's going to be like any other table or view in the list - it will be first

  select b.BUSINESS_OBJECT_CATEGORY_DESCR, a.c, a.d
  from
   (select PAY_METHOD_TYPE_CODE, BUSINESS_OBJECT_CATEGORY_CODE
    from target_odi.business_object_pay_methods)
   pivot (count(PAY_METHOD_TYPE_CODE)
           for PAY_METHOD_TYPE_CODE in  ('D' as d, 'C' as c)) a ,
  target_odi.business_object_categories  b
  where a.BUSINESS_OBJECT_CATEGORY_CODE = b.BUSINESS_OBJECT_CATEGORY_CODE
  

  So for the SQL above the pivot is first assessed before the join between A and B.

• uniol all in the select statement

  Hi I have a situation where I have to return the value based on the if statement, is it possible to put union all in the select statement

  My use case is

  IN the column State

  If column01 > 0 to condtion 't'

  IF column02 > 0 that the condition of 'Y '.

  Condition IF COLUMN03 > 0 THAN 'w '.

  If COLUMN04 > 0 that the condition of "Z".

  Select 't'

  TableName

  where column01 > 0

  Union of all the

  Select "y".

  TableName

  where column02 > 0

  Union of all the

  Select 'W '.

  TABLENAME

  WHERE COLUMN03 > 0

  I have what it takes to show value as it

  EmpName, condition, empno

  Jerry, T, 0158754585

  TOM, Y, 0054789568

  Am in oracle database 11 g 2

  Yes you can put all THE UNION here

  Select empname, 't' State, empno from tablename where column01 > 0

  Union of all the

  Select empname, 't' State, empno from tablename where column02 > 0

  Union of all the

  Select empname, condition of "W", empno FROM tablename WHERE COLUMN03 > 0

  Union of all the

  Select empname, condition of "Z", empno FROM tablename WHERE COLUMN04 > 0

  and if you are looking for how to remove duplicates because your line might have satisfied all the conditions and my happen 4 times in your result set, you just need to give them an order and filter it.

  For example, you want this

  If column01 > 0 to condtion 't'

  ELSE IF column02 > 0 that the condition of 'Y '.

  Another condition of THAN > 0 IF COLUMN03 'w '.

  otherwise if COLUMN04 > 0 that the condition of "Z".

  Select empname, condition, empno, in

  (

  Select a.*, row_number() over (partition by empno arrested by myorder) rn

  Of

  (

  Select empname, 't' State, empno, 1 myorder tablename where column01 > 0

  Union of all the

  Select empname, 't' State, empno, 2 myorder tablename where column02 > 0

  As mentioned previous you are best to check the documentation. Here is an excerpt from the documentation on this topic (emphasis added):

  Limitation to fast refresh materialized views with joins only

  Definition of materialized views with joints only and no aggregate queries have the following restrictions on fast refresh:

  * All 'General Restrictions on Fast Refresh' restrictions.
  * They cannot have aggregate or GROUP BY clauses.
  * The ROWID of all tables in the list must appear in the SELECT list of the query.*
  >

  For example, if the problem is that when you describe the view you have ROWID and you don't want them there, then I suggest to implement a regular vision on top of the materialized view that hides these columns.

  ex: select col1, col2
  from my_table
  where my_package.my_function (32199, 2008, col3, 'P');
  
  and I have the error message ' ORA-00920: invalid relational operator.
  
  FUNCTION ma_fonction (v_matricule in NUMBER,
  v_Year in NUMBERS
  T_DATE IN a DATE,
  v_type in DEFAULT CHAR 'P')
  RETURN A BOOLEAN VALUE;
  
  @+ Rosagio

  Yes, it is possible.

  But you have no relational operator:

  where my_package.my_function (32199, 2008, col3, 'P') =?
  where my_package.my_function (32199, 2008, col3, 'P') >?
  where my_package.my_function (32199, 2008, col3, 'P')<>

  Oops, I just noticed that your function returns a Boolean value.

  Can't do that as in a SQL statement.

  Boolean is known only to other code PL/SQL, no SQL statements.

• mixture of column type in the select statement

  Oracle 11g r2.

  tab_test (name varchar2, blob... photo)

  (1) select general use *.

  Stored procedure: open ref_cursor to some * of table_test...

  Coast of java: call.registerOutParameter (1, OracleTypes.CURSOR);  Call.Execute ();

  It works very well.

  (2) enter the name of the column in the select such as

  Stored procedure: open ref_cursor to select name, photo table_test...

  Coast of java: call.registerOutParameter (1, OracleTypes.CURSOR);  Call.Execute ();

  ERROR: java.sql.SQLSyntaxErrorException: ORA-00932: inconsistent data types: expected - got BLOB

  My question, if I specify the column names in the select statement, including the varchar2 and blob, how can I registerOutParameter (1, OracleTypes.CURSOR);?

  Thank you

  Scott

  PS The number of returned columns, in real case schenario, is a little, so I prefer to specify column names.

  Wrong forum. This forum is for questions of sql and pl/sql.

  Enter the question ANSWER and the repost in the JDBC forum

  https://community.oracle.com/community/developer/english/java/database_connectivity/java_database_connectivity _(jdbc)

  When repost you provide the necessary information to help you:

  1. information on the full version for Oracle DB

  2 version of the JDK

  3. the name and version of the JDBC jar file

  4. real code that demonstrates the problem

  You should also review the info re REF CURSOR in the JDBC Developer's Guide

  Can' are you use PIVOT here since you do not know from the start what values OTBOOKEDDATE. So use:

  select  empno,
          otbookeddate - weekday + 1 otbookeddate,
          max(
              case weekday
                when 1 then dayceilinghrs
              end
             ) day1_hrs,
          max(
              case weekday
                when 2 then dayceilinghrs
              end
             ) day2_hrs,

• validation for each 1,000 records to be inserted in the select statement

  Hi, I have the following INSERTION in the SELECT statement.
  The SELECT statement (who joined) data fo about 6 crores. I need to insert this data into another table.
  
  Please suggest me the best way to do it.
  I use the INSERT in the SELECT statement, but I want to use the statement commit for each 1,000 records.
  
  How can I do this...
  

  insert into emp_dept_master 
   select e.ename ,d.dname ,e.empno ,e.empno ,e.sal 
     from emp e , dept d
    where e.deptno = d.deptno       ------ how to use commit for every 1000 records .

  Thank you

  Method 4 is the best

  You could combine method 3 and 1 (without dynamic SQL)

  Method 2 is the less optimal solution from the list.
