• Any difference between the separate function and aggregation in sql query cost?

  Hello
  I've run many models sql stmts - such as:
  one) using a single table
  (b) using the two tables, using simple joins or outer joins
  
  but I didn't notice a difference in sql stmts in cost and implementation plan...
  In any case, my colleague insists on only using the aggregate function is less expensive compared to
  separate... (something I've not confirmed, that is why I believe that they are exactly the same...)
  
  For the situation described above under 1 sql... We could for example use
  

  select distinct deptno
  
   from emp

  select count(*), deptno
  
   from emp
  
   group by deptno

  select distinct owner, object_type from all_objects

  select count(*), owner, object_type from all_objects
  
  group by owner, object_type

  Have you ever found no difference between the two...?
  
  Note: I use Ora DB 10g v2.
  
  Thank you

  Alexandre Gelin says:
  function separate and aggregation are for different uses and can give the same result, but if you use the aggregate function to get the separate records, it will be expensive...

  really? I find them almost identical to 11g. Actually GROUP BY is almost always more fast for me in the old days.

• How to create the constructor function for a pl/sql table?

  I created a PL/SQL type as table below:

  create or replace type typ_tbl_des_text is table of the typ_tof_des_text

  OK so far, but I would like to have a constructor function which would be subject to validations and raise_application_error when a validation condition is not met.

  How to do this?

  The typ_tof_des_text that I created with a constructor function, so that the record-level validation are performed in the constructor. And I think the postings between several records shall be made in a constructor for typ_tbl_des_tex, but cannot figure out how to create such a constructor.

  BEDE wrote:

  So, if I have understood correctly, to a plsql table type, I can't have a member procedure. Or can I? I mean, just as for a type of failure I can have one or more constructors and possibly several procedures of Member.

  For the standard tables in PL/SQL, you will need to create your own API (using procedures and functions) to handle beyond the basics provided by the language. No constructors and methods as it is no o - o.

  After thinking a little deeper, I reformulate what I said earlier and actually wants to have a member procedure called add_item, who would be first to check if an item with a key value exists and, if so, it would be up-to-date and so not only extend the plsql table.

  Two options.

  As we already mentioned, an associative array can be considered - note however that this structure of table has name-value pairs.

  Another method is to use a TWG (global temporary table). You define the structure of the once initial table. When a session uses the structure of the table, private copying is instantiated for this session. When the session ends, this copy is destroyed. The table is a temporary structure for this session only.

  It can include indexes and so on – which means you can use the constraints of primary keys, unique indexes, secondary indexes and so on.

  TWG scales are much better than collections or arrays that require a PGA (expensive private server) memory. In addition, SQL can be used natively against a GTT - unlike the arrays and collections.

• Convert a MySQL function in Oracle PL/SQL

  
  Hello

  I'm trying to transfer a MySQL database in Oracle 12 c, there are a number of functions that I need to convert since I am new to Oracle and PL/SQL in particular, I would really appreciate your help for the conversion:

  CREATE FUNCTION get_customer_balance()p_customer_id INT p_effective_date DATETIME() RETURNS DECIMAL()5,2( )

  DECLARE v_payments decimal PLACES ()5,2) ; #SUM OF PREVIOUSLY MADE PAYMENTS
  
  SELECT IFNULL (SUM(film. rental_rate ),0) INTO v_rentfees
  FROM film , inventory , rental
  WHERE film . film_id = inventory . film_id
  ET inventory . inventory_id = rental . inventory_id
  AND rental . rental_date <= p_effective_date
  AND rental . Customer_ID = p_customer_id ;
  
  SELECT IFNULL (SUM(IF((TO_DAYS(rental. return_date ) - TO_DAYS(rental. rental_date )) > film. rental_duration ,

  This means that rental.return_date and rental.rental_date are declared as a TIMESTAMP. Question is why? Return_date/rental_date store fractions of a second? In any case, assuming rental_duration is in days:

  WHEN rental.return_date - rental.rental_date > numtodsinterval (film.rental_duration, 'day')

  But the question is return_date and rental_date stores it part time too. I assumed that he didn't, and simply omitted TO_DAYS. If so, then TO_DAYS should be translated to TRUNC:

• Find the function object DB with SQL Developer

  Hello to all, SQL developer 4.0.0.13 on Windows 7 64 bit version. I just started to use the function of object find DB. I type the name of the object in the worksheet, select the name of the object and press ALT + g pane, tab, palette, dialogbox binocular opens and shows me all the objects (and schema name) which are referred to as the selected text in the worksheet. When you click on the name of the object, the object opens twice in the object browser. Maybe I understood something wrong. I tried clicking on it once and twice, twice, I see two viewers object showing the same object. Also the pane, tab, palette, dialogbox binocular remains open after that. Is there a way I can hide/close this as soon as I click on the object. Thank you for your help in advance.

  the search panel will remain open until you hide/close it

  I'm not able to reproduce the problem of double-open - what type of object happens to, or she to what whether you click on?

  In addition, you are on an older version, you can upgrade to 4.0.2 because it could have been corrected in a 2 patch releases as your version debuted.

• calling a function of R in sql

  Hello, can someone help me on this query?

  (1) I have a data view called Q_X1_V stored in a database schema, which contains a column called OBS03

  (2) I have connected to the schema where the above mentioned notice is defined using sqldeveloper

  (3) I created the function of R following and performed in sql developer

  Library (Ore)

  Ore.Sync (table = Q_X1_V)

  Ore.Attach)

  DataSet <-ore .pull (Q_X1_V ["OBS03"])

  He created the function successfully.

  (4) and I'm trying to run the following sql query in sql developer

  Select *.

  table (rqEval (NULL, "select 1"OBS03"of the double ',' xbarr-QCC '));

  Any help is appreciated.

  Thank you

  Pradeep

  If you have not already established a database connection by using ore.connect, you will need to include this in your script:

  Start

  sys.rqScriptDrop('xbarr-qcc');

  sys.rqScriptCreate ('xbarr-QCC ',' function() {})

  Library (Ore)

  Ore.Connect ("user", "sid", "hostname", "password") # use your credentials

  Ore.Sync (table = "Q_X1_V") # Note that the table name must be quoted as a string

  Ore.Attach)

  DataSet<->

  Head (DataSet)

  }');

  end;

  Select *.

  table (rqEval)

  NULL,

  "select 1"OBS03"double."

  "xbarr-QCC"));

  Or, if a database connection has been established, omit the ore.connect statement in your script and use the optional "ore.connect" parameter in the call to rqEval.

  This will call your user credentials to connect to database:

  Select *.

  table (rqEval)

  cursor (select 1 "ore.connect" of the double).

  "select 1"OBS03"double."

  "xbarr-QCC"));

• Helps the function 'Running background PL/SQL'

  Hello everyone.

  I come here for assistance with the service running background PL/SQL within the APEX. Here's a background of what I have to do.

  Background:

  Currently, I have just a page with a button above and some display boxes. The button calls a process flow Oracle Warehouse Builder (OWB) named RUN_ADJ_VAR and does what he must do. That works fine if my button simply calls the PL/SQL code of

  BEGIN

  ETQUEW. RUN_ADJ_VAR;

  END;
  

  Now that I know that the process flow and the button are working fine, I need to make the page "intelligently" by limiting multiple submissions until the process ends.

  What I need:

  I need assistance with running background PL/SQL function. My work has been running for a while and I need to run in the background and provide a status of the user, while restricting another presentation by the user. From what I've read here:

  Advanced programming techniques

  According to me, that this DBMS wrapper function, it's what I use.

  What I have so far:

  Using the API and example, I made my own attempt at this and it does not work. Here's what I have so far:

  [code]

  DECLARE

  v_sql VARCHAR2 (32767).

  BEGIN

  v_sql: = '

  BEGIN

  ETQUEW. RUN_ADJ_VAR;

  APEX_PLSQL_JOB. () UPDATE_JOB_STATUS

  P_JOB = >: APP_JOB,.

  P_STATUS = > "done");

  END IF;

  END;

  ';

  : P1_JOB: = APEX_PLSQL_JOB. () SUBMIT_PROCESS

  p_sql = > v_sql,

  p_when = > sysdate,.

  p_status = > 'Submit');

  : P1_POST_DONE: = 'Y ';

  END;

  [/ code]

  What the code so far:

  The code seems to ignore the first part and does work through the underlined only section. The work never appears to run and the button can be clicked several times.

  Other Options:

  I don't know if the function from PL/SQL background running is the only way to do that. The work is performed for about 15 minutes so I can't use a javascript script wait indicator since that will expire because of the hours of work. I searched all over the internet and forums and I feel I have exhausted all my options. I am very new to the APEX and PL/SQL in general, so your help is very appreciated.

  Thank you!!!

  Hello Konrad B.!

  Try to rewrite the code as shown below:

  DECLARE

  v_sql VARCHAR2 (32767).

  BEGIN

  v_sql: = '

  BEGIN

  ETQUEW. RUN_ADJ_VAR;

  END;

  ';

  : P1_JOB: = apex_plsql_job.submit_process (v_sql);

  END;

  Assume that P1_JOB - question on the page. After submitting the job, this point will be containing number of jobs. The job number,
  username (can get APP_USER) and workspace id (can get WORKSPACE_ID) you can check the status
  view of working level (field SYSTEM_STATUS) APEX_PLSQL_JOBS:

  SELECT SYSTEM_STATUS
  FROM APEX_PLSQL_JOBS
  WHERE JOB = :P1_JOB
  AND ANDUSER = :APP_USER
  AND SECURITY_GROUP_ID = :WORKSPACE_ID
  

  So you can make conditional button, selected example condition "NOT Exists (SQL query returns no rows)" and in the expression type:

  Select 1 from apex_plsql_jobs

  where employment =: P1_JOB

  and end user =: APP_USER

  and security_group_id =: WORKSPACE_ID

  and system_status in ("in PROGRESS", "SUBMITTED")

  If you must run the job for the user, then button will not be returned.

• Why the MAX aggregate function is used in SQL upon accession of the fields created in the designer?

  Of course Certified Developer, you can see the left join to include the fields in the SU_EXTENTION_DATA table. Why MAX is used when retrieving these values?

  ! Wont start-

  LEFT JOIN

  (SELECT

  REF_NO "REF."

  MAX (CASE WHEN EXTENSION_FIELD_REF = 500033 THEN VALUE_DATE END) "DOB",.

  MAX (CASE WHEN EXTENSION_FIELD_REF = VALUE_STRING END THEN 500034) "E_CONTACT."

  MAX (CASE WHEN EXTENSION_FIELD_REF = 500035 THEN VALUE_STRING END) "E_CONT_NO."

  MAX (CASE WHEN EXTENSION_FIELD_REF = 500036 THEN VALUE_TEXT END) "MED_HIST."

  MAX (CASE WHEN EXTENSION_FIELD_REF = 500037 THEN SELECT_TEXT END) 'PREF_CONTACT '.

  OF SU_EXTENSION_DATA

  LEFT JOIN SU_SELECT_VALUES ON

  SU_EXTENSION_DATA. VALUE_SELECT = SU_SELECT_VALUES. REF

  WHERE CORE_ENTITY = 5

  REF_NO GROUP) X ON AR_PERSON. REF = X.REF

  ! End custom-

  When you do you must include all the fields that have been selected as criteria for grouping the aggregation OR use false features like MAX (more likely it's easier way when the result field is expression).

• pl/sql appellant java class member function obtains ora-00932 in 11g.

  Call a member function of class of java from a pl/sql script, I get an error ora-00932.

  ORA-00932: inconsistent data types: waiting for an IN argument in position 1 which is an instance of an O

  convertible to an instance of a user defined class Java got a type of Oracle that could not be converted

  The code works fine when the java function is declared static.   However, since there could be thousands of users hitting the function at the same time and there is no instance of the object, I wasn't sure if it would be a matter of how oracle manages memory for each user in a session, if it would not be a problem, I can go forward with this approach.   However, I have greatly simplified this for an example that reproduces the problem.

  Create the oracle type:

  CREATE OR REPLACE TYPE MyObject AS OBJECT

  (

  col1Data VARCHAR2 (10),

  MEMBER FUNCTION createData

  RETURN VARCHAR2 AS LANGUAGE JAVA

  NAME "java.lang.String return MyObject.createData ().

  );

  Java code:

  CREATE OR REPLACE AND FIX JAVA SOURCE NAMED 'MyObject' AS

  import java. IO;

  public class MyObject

  {

  private String col1Data;

  public void createData)

  {

  System.out.println ("col1:" + col1Data);

  }

  }

  Java function call vai pl/sql function:

  FUNCTION to CREATE or REPLACE fn_myobject

  (col1 IN varchar2)

  RETURN VARCHAR2

  AS

  p_rc varchar2 (100);

  myObj MyObject;

  BEGIN

  myObj: = new MyObject (col1);

  p_rc: = myObj.createData ();   -This line gets an error 00932

  RETURN p_rc;

  END;

  /

  And finally, the script from sqlplus to test:

  Set serverout

  call dbms_java.set_output (50);

  Set line 120

  declare

  VARCHAR2 (64) RC: = ";

  R1 varchar2 (64): = 'abc ';

  Start

  RC: = fn_myobject (r1);

  end;

  /

  I tried all sorts of things without success.   Any ideas on this would be most appreciated.  It is once again, 11g.

  Thank you.

  MarkF says:

  If you go back to the example code I posted, it is mapping a java class oracle object.

  No, it isn't.

  Your example simply sets an Oracle object type whose member createData function is implemented in Java.

  The fact that the implementing class has the same name does not have a direct mapping between the class and the type of Oracle.

  The important part to read and understand in the link I posted is:

  A call specification outlines the top level of an Oracle database Java method entry point. So, you can publish only public static methods.

  However, there is an exception. You can publish instance methods as members of an SQL object type methods.

  You are in the first case.

  To be in the exceptional cases and be able to publish instance methods, the Java class must implement SQLData.

  See the latest example here:

  https://docs.Oracle.com/database/121/JJDEV/chsix.htm#JJDEV13273

  Adapted to your example:

  CREATE OR REPLACE AND compile JAVA SOURCE NAMED "MyObject" AS
  import java.sql.*;
  
  public class MyClass implements SQLData
  {
    // Implement the attributes and operations for this type.
    private String col1Data;
  
    public String createData ()
    {
        System.out.println ("col1: " + col1Data);
        return col1Data;
    }
  
    // Implement SQLData interface.
    String sql_type;
  
    public String getSQLTypeName() throws SQLException
    {
      return sql_type;
    }
  
    public void readSQL(SQLInput stream, String typeName) throws SQLException
    {
      sql_type = typeName;
      col1Data = stream.readString();
    }
  
    public void writeSQL(SQLOutput stream) throws SQLException
    {
      stream.writeString(col1Data);
    }
  }
  /
  

  CREATE OR REPLACE TYPE MyObject AS OBJECT
  (
    col1Data  VARCHAR2(10),
    MEMBER FUNCTION createData
            RETURN VARCHAR2 AS LANGUAGE JAVA

• A c from pl/sql function call

  Hello

  I'm testing a simple case to call a C function from a pl/sql block.

  Here's my test case (came to BillyVerreynne :-):)

  TST.c:

  #include < ctype.h >

  #include < stdio.h >

  int upcase (char * istr, char * ostr)

  {

  int i = 0;

  While (ISTR)

  {

  OSTR [i] = toupper (istr [i]);

  i ++ ;

  }

  return 0;

  }

  // compile
gcc -fPIC -c tst.c

// create shared object

ld -shared -o libtest.so tst.o

file libtest.so

libtest.so: ELF 64-bit LSB shared object, AMD x86-64, version 1 (SYSV), not stripped

// wrapper library and function

SQL> create or replace library libtest as '/home/oracle/libtest.so';
/

  How I did wrong?

  Thanks a lot for your help

  The error means generally that your external procedure (process c in this case), failed or crashed.

  The details of the Oracle error:

  28576, 00000, "loss of the RPC connection to the external procedure agent."
  * Cause: A fatal error occurred either a RPC network connection.
  agent extproc or the invoked 3GL after disclosure
  was created successfully.
  * Action: First check the 3GL code you are calling; the most likely
  This error is an abnormal termination of the
  called 'C' routine. If this is not the case, look for
  network problems. Correct the problem if you find. If all the
  components appear normal, but the problem persists, the
  problem could be an internal logic error in the transfer of the CPP
  code.  Contact your customer support representative.

  Probably the dynamic loader used by the kernel to resolve external dependencies than physical of the executable failed?

  Mike Board solves the problem? IMO, it should...

• Can you pass a SQL function?

  I have the following function:

  CREATE OR REPLACE PROCEDURE run_query (p_sql IN VARCHAR2) IS

  v_v_val VARCHAR2 (4000);

  v_n_val NUMBER;

  v_d_val DATE;

  v_ret NUMBER;

  c NUMBER;

  d NUMBER;

  col_cnt INTEGER.

  f BOOLEAN;

  rec_tab DBMS_SQL. DESC_TAB;

  col_num NUMBER;

  v_rowcount NUMBER: = 0;

  v_csv VARCHAR2 (32000);

  BEGIN

  -create a slider

  c: = DBMS_SQL. OPEN_CURSOR;

  -analyze the SQL statement in the cursor

  DBMS_SQL. PARSE (c, p_sql, DBMS_SQL. NATIVE);

  -run the cursor

  d: = DBMS_SQL. Execute (c);

  --

  -Describe the columns that are returned by the SQL statement

  DBMS_SQL. DESCRIBE_COLUMNS (c, col_cnt, rec_tab);

  --

  -Local variables Bind to return to the different columns according to their types

  1.col_cnt J

  LOOP

  CASE rec_tab (j) .col_type

  WHEN 1 THEN DBMS_SQL. DEFINE_COLUMN (c, j, v_v_val, 2000); -Varchar2

  WHEN 2 THEN DBMS_SQL. DEFINE_COLUMN (c, j, v_n_val);      -Number

  ON THE OTHER

  DBMS_SQL. DEFINE_COLUMN (c, j, v_v_val, 2000);  -Any other type of return as varchar2

  END CASE;

  END LOOP;

  -Extract the value of each column of the row

  LOOP

  -Fetch each column to the correct data type according to the description of the column

  CASE rec_tab (j) .col_type

  WHEN 1 THEN DBMS_SQL. COLUMN_VALUE (c, j, v_v_val);

  v_csv: = v_csv | «, » || v_v_val;

  It allows to feed in an arbitrary query and returned a set of data comma separated. For example:

  SQL > run_query exec ('select * from scott.emp where deptno = 10');

  7782, CLARK, MANAGER, 7839, 1981/09/06 00:00:00, 2450, 10

  7839, KING, PRESIDENT, 17/11/1981-00:00:00, 5000, 10

  7934, MILLER, CLERK, 7782, 1982/01/23 00:00:00, 1300, 10

  PL/SQL procedure successfully completed.

  SQL > exec run_query ("select * from (select * from scott.emp where deptno = 10 order by sal desc) where rownum < 5'");

  7839, KING, PRESIDENT, 17/11/1981-00:00:00, 5000, 10

  7782, CLARK, MANAGER, 7839, 1981/09/06 00:00:00, 2450, 10

  7934, MILLER, CLERK, 7782, 1982/01/23 00:00:00, 1300, 10

  (I'm not saying that it is a good practice: on the contrary.) But it is a requirement that was worth and I need to know how to cope, not arguing with it).

  My question is: the code works when the application before she includes not single quotes. As soon as he does, he died:

  SQL > run_query exec ('select 'Example', sal scott.emp where deptno = 10');

  BEGIN run_query ('select 'Example', sal scott.emp where deptno = 10'); END;

  ORA-06550: line 1, column 26:

  The symbol ", has been inserted before"EXAMPLE"to continue."

  I could of course escape quotation marks simple "internal", but the goal is for end-users to feed in their queries, without having to rewrite with delicate escape sequences!

  So the question is: is there a way I can allow users to feed their SQL in the procedure without having to worry about the single quotes that might be in the middle of it?

  Still, I realize has the risk of SQL injection... but I would like to help on the practicalities of quotes, not managing a risk which I am aware (and dealing with outside the procedural code, that I showed here).

  In other words, even if you think it's the worst idea in the world, I still want to know how I could feed 'select 'Example', sal scott.emp where deptno = 10'procedure that it is correctly.
  

  Is there a character that you can be reasonably confident does not appear in the SQL statement?  If so, you can probably use the q citing the syntax.  For example

  SELECT q'{select 'a', 'b', 'c' from dual}'
    FROM dual
  

  who can get applied to the call to function as well

  SQL> exec run_query( q'{select 'a', 'b', 'c' from dual}' );
  a
  b
  c
  
  PL/SQL procedure successfully completed.
  

  If you can be reasonably sure that there is no {or} character (or a number of other pairs), you can just that wrap the SQL statement.  Of course, this assumes that there is some bit of code enforcement between the user and the procedure call that can add to the {and}.  If this is the case, you could also just double apostrophes that meet you.
