• % SQL rowcount returns 1, but he should return 2

  Oracle 10g

  Hi gurus

  I was reading one of the PL/SQL challenge site https://plsqlchallenge.oracle.com/pls/apex/f?p=10000:23:114157934581224:NOquestion: but can't get the exact idea.

  I appreciate if someone helps me to understand the code.

  Examples of data

  Set serveroutput on
  /
  drop table plch_stuff;
  /

  CREATE TABLE plch_stuff)
  ID INTEGER PRIMARY KEY,
  NM SINGLE VARCHAR2 (5))
  /

  create or replace procedure (plch_insert)
  insert_row_in IN BOOLEAN DEFAULT true)
  IS
  Start
  IF insert_row_in
  THEN
  INSERT INTO plch_stuff VALUES (1, 'Hat');
  END IF;
  END;
  /
  Start
  plch_insert;
  UPDATE plch_stuff SET nm = 'Hat ';
  dbms_output.put_line (' last count ='|) SQL % ROWCOUNT);
  END;

  Result

  Last Count = 1

  But according to my understanding, result = last count = 2 because a sql % rowcount for insert and then one to update. Please guide. Thank you

  Where did you got your "understanding"?

  When you have questions about the basic features Oracle, you must ALWAYS first check the documentation.

  A search on the web for "oracle 11g sql % rowcount" returns this as the first link

  http://docs.Oracle.com/CD/B28359_01/AppDev.111/b28370/sql_cursor.htm

  % NUMBER OF LINES

  Returns the number of rows affected by a INSERT , UPDATE , or DELETE or returned by a statement SELECT INTO statement.

  The County refers to one, AND only ONE, statement - the last statement executed.

• SQL ROWCOUNT %

  When I use SQL % ROWCOUNT, it returns the account = 1 if there is no record of the PRODUCT in the condition table

  SELECT count (*) from the PRODUCT v_count WHERE LOC = v_oldloc;

  dbms_output.put_line (' documents found in the PRODUCT table for column LOC with the value ' | v_oldloc |': ' |) SQL % ROWCOUNT);

  COMMIT;

  But, when I use the v_count to display the number of records, it returns ZERO (correct) as below

  SELECT count (*) from the PRODUCT v_count WHERE LOC = v_oldloc;

  dbms_output.put_line (' documents found in the PRODUCT table for column LOC with the value ' | v_oldloc |': ' | v_count);

  COMMIT;

  Please let me know if there is a problem with the code?

  Thanks in advance

  Hello

  % ROWCOUNT SQL returns you the number of lines that returns the query "SELECT count (*) in v_count PRODUCT WHERE LOC = v_oldloc;

  In fact, the query returns a row with the value 0. This is why SQL ROWCOUNT % gives you 1 as output.

  Of course v_count is 0 because it is what is the result of the query.

  Both are expected results in your case.

• SQLCODE and sql rowcount % in test conditions

  I'm translating a procedure of Ingres to oracle. I use the Oracle sql and sqlcode % rowcount
  variables instead of Ingres, iierrornumber and iirowcount.
  
  I replaced the names of ingres with the names of oracle and now wonder how how oracle uses these
  values.
  
  I use DBMS_OUTPUT. Put_line to display the content of rowcount % sqlcode and sql.
  
  What happens when I'm 'without selected lines. I have run the same query in the stand-alone command line
  and don't get any selected rows... "(and that's okay, because I do not have the corresponding data to)."
  
  But when I run it in the procedure, I don't get any value of sqlcode or sql % rowcount... the
  program just stops. The author used the ingres code to test if the data were there
  continue to do something else.
  
  If you get no rows returned, what it means, the sqlcode is 0? and the number of lines % sql is empty?
  That's why my DBMS_OUTPUT. Put_line does not display anything?
  
  my example...
  
  before this section in proceedings... after running another select statement that returns data...
  I use the DBMS to debug the values I spent...
  
  DBMS_OUTPUT. Put_line ('BEFORE sqlcode is' | sqlcode);
  DBMS_OUTPUT. Put_line ('until sqlrowcount is"| % rowcount sql);
  
  Select the table value
  WHERE condition = "Y"; > This selection will be made 'no return lines' and ignore the below DBMS_OUTPUTS - 2
  
  DBMS_OUTPUT. Put_line ('AFTER sqlcode is' | sqlcode);
  DBMS_OUTPUT. Put_line ("AFTER sqlrowcount is" | % rowcount sql);
  
  When I run the procedure... I get statements DBMS BEFORE and nothing after...
  BEFORE sqlcode is 0
  Sqlrowcount is 1 > > > > that's all that is displayed
  
  
  Given that I'm getting the 'no row returned. How oracle it round to the experience of someone?
  
  Thank you. I learn a lot from your comments and your information.

  Show us the full procedure please.

  I'm guessing that you have a generic WHEN catch of OTHER exception that swallows the NO_DATA_FOUND exception I expect to see (depending on what you posted).

• Is it wrong to use SQL % ROWCOUNT = 0?

  Hello
  
  I have two tables, BILL and VALIDATIONS, have all two (LDAP_UID, TERM) as a composite key. I wrote a procedure to do the following:
  
  1. I use this composite key to extract some the key fields from the table of BILL, form a new row and insert it into the table VALIATIONS;
  2. prior to inserting into the table of VALIDATIONS, I use a SELECT statement to verify if the composite key already exists in the table of VALIDATION and not inserting at least that the composite key is not found.
  
  The procedure is the following:
  

  create or replace procedure save_transactions
     (i_ldap_uid IN varchar2, i_term IN varchar2)
  AS
     v_validated_ldap_uid validations.ldap_uid%type;
     v_student_id validations.student_id%type;
     v_first_name validations.first_name%type;
     v_last_name validations.last_name%type;
     v_term validations.term%type;
  BEGIN
     select ldap_uid
     into v_validated_ldap_uid
     from validations
     where ldap_uid = i_ldap_uid
     and term = i_term;
  
     if SQL%ROWCOUNT = 0 then
        select student_id, first_name, last_name
        into v_student_id, v_first_name, v_last_name
        from bill
        where ldap_uid = i_ldap_uid
        and term = i_term;
        insert into validations values (
        v_student_id, i_ldap_uid, v_first_name, v_last_name,
        i_term, sysdate, (to_char(sysdate, 'yymmdd'))||
        (select to_char(count(TRANSACTION_DATE)+1, 'fm0999') from VALIDATIONS where to_char(TRANSACTION_DATE) = to_char(sysdate))
        );
     end if;
  END;
  /

  The procedure is created and updated clean, without any error. But the error occurs when using it. If the line is already in table VALIDATIONS, the {color: blue} if SQL % ROWCOUNT = 0 {color} is fine and the insertion code block is bypassed. However, if the line is not found in the table of VALIDATION, I got the following error:
  

  SQL> execute save_transactions('john.brown', '200902')
  BEGIN save_transactions('john.brown', '200902'); END;
  
  *
  ERROR at line 1:
  ORA-01403: no data found
  ORA-06512: at "ZBOV.SAVE_TRANSACTIONS", line 10
  ORA-06512: at line 1

  Well, for me, the whole use of SQL % ROWCOUNT is for testing. If he cannot test SQL ROWCOUNT = 0%, how else can test? However, I got the error and I must be wrong. But what is bad?
  
  Thanks a lot for your help!

  Hello

  The "no data found" error is raised whenevde make you a select... IN the query and the query found no line.
  You can always include SELECT it... IN his own statement BEGIN block, with its own «EXCEPTION WHEN NO_DATA_FOUND» Manager... ", but often, there are easier ways to work around the problem.

  In this example, I can see two of these ways:

  (1) Say

  SELECT  COUNT (*)
  INTO    num_found
  FROM    transactions
  WHERE   ldap_uid = i_ldap_uid
  AND     term     = i_term;
  
     if num_found = 0 then
  ...
  

  "SELECT COUNT...". "without a GROUP BY will always return exactly one line, if you do not have to worry about the error"no data found ".

  (2) a better (but more difficult) solution: instead of making a "INSERT...". Statement of VALUES... ', using the results of the query on the Bill, make a

  INSERT  ...
  SELECT  ...
  FROM    bill
  WHERE   ...
  AND     NOT EXISTS
          (
          SELECT  1
          FROM    validations
          WHERE   ldap_uid = i_ldap_uid
          AND     term     = i_term
          );
  

  In fact, you have PL/SQL to do this (although there are good reasons to have a PL/SQL procedure that does nothing other than this INSERT statement).

• The coldfusion.sql.QueryTable value cannot be converted to a number

  Hello

  I have two queries, in two different functions, who both return the SUM of a column based on the values of the arguments

  I need to subtract query from a query of 1 2.

  The arguments for the two motions are passed using the CreateObject function

  < cfset qry1 = createObject ("component", "components.adminobjects"). Func1(#argument1#,#argument2#) >

  < cfset qry2 = createObject ("component", "components.adminobjects"). Func1(#argument1#,#argument2#) >

  Queries executed accordingly and returns the results accordingly.

  The problem occurs when I try to calculate by subtracting the 2nd request form 1.

  So, to get the results I need, that's what I do:

  < cfset results = ' #qry1.sum # '-' #qry1.sum2 # ' >

  < cfoutput > #results # < / cfoutput >

  When I do this, it is said:

  The coldfusion.sql.QueryTable value cannot be converted to a number

  I don't understand, it is because when I exit #qry1.sum # or #qry1.sum2 # I get the numbers right and they are numbers, but when I do some math on them, I get the error.

  Any ideas?

  Thank you.

  Assuming that the qry1 object has a column named "sum1" and "sum2" try:

  Also note that the "sum" is a reserved word, try to change the column "sum" "sum1".

• How to read the BIT of SQL Server value in CVI

  Hello

  I try to get a value of SQL Server 2005 (ture or false) bit in CVI (with SQL toolkit). I use the DBBindInt, but overall the return value is - 1.

  How can I get the real value of SQL?

  Thanks for your help

  Region

  Do you mean that you never receive the value FALSE, IE 0? Or you expect a TRUE value to be exactly 1? It is very common for TRUE to be represented as -1; If you are concerned just hide all the bits in the value returned with the exception of bit 0 - this will then give your alternative 0/1.

• SQL HASH value?

  1. yesterday a request i run it took 1 min but today it is almost 5 minutes.

  could u please explain to me what is right.

  is it possible to run a query with the particular hash value, I want to say I can run this same query using the yesterdays hash value. ?

  > I mean I can run this same query using the yesterdays hash value

  No, you cannot use the HASH_VALUE or the SQL_ID of a SQL ' execute the SQL.  You must re-enter the SQL in the SQL (for example sqlplus or sqldeveloper or Toad) interpreter to run it.

  Hello

  You can change your guest here you can find the show option, and then choose SQL result please change statement as below.

  SELECT the name of your column OF field where your name of the column is not null

  Go--> change your prompt--> Show--> Sql select result---> statement change as above.

  Second way.

  Go to the layer, and then double click on your column name here you can find * 'Nullable' * option please check.

  Go--> physical layer--> extract table--> select your name in the column--> double click on your name in the column--> here you can find option as Nullable, please check.

  Allocation of points, it is useful.

• Guest column SQL limit values results filter

  I have a prompt Filter column showing values based on sql: SELECT task. "" Saw_0 task name ' OF THE 'Project - Cost' ORDER BY saw_0. This sql works and shows all tasks. However, I would like to have this prompt limits based on the prompt. As the option of limited values.
  
  Example: The user is prompted to select a project. The user has an lov and selects a project (s). Then, I would have the second guest with sql (SELECT task.) ("' Saw_0 name of the task" OF THE 'Project - Cost' ORDER BY saw_0) limit values selected on the first prompt. How do I would change sql to do this?
  
  Thank you

  If built correctly, you can check the checkbox 'Coercion' to the line of dashboard (you can not use a guest column for that!) and the task list would be forced by the selection of the prompt project.

  Otherwise, you must the guests of dashboard (with 2 'Go' buttons).

  The first prompt will have your projects you need to save a variable presentation, say pv_Project

  In the second line, you click the drop-down "Show" menu and change to "SQL results. Then, you need to add at the end of the SQL statement, which suite:

  WHERE the table. "Project = ' @{pv_Project}"

  If its 3 days it would be aged. Since you're on 10g, try mark dba_hist_sql_text who would be the oldest stored sqls provided your AWR retention period is in order.
