• FORALL with EXECUTE IMMEDIATE

  Hi all
  
  I'm using Oracle 11 g Release2.
  
  I need to use the forall with EXECUTE IMMEDIATE statement and the content of string inside EXECUTE IMMEDIATE is a SELECT instead of the usual DML statement.
  
  Objective: In this SELECT statement, I'll be passing of data using the "USING" clause in FORALL statement
  
  When I try to use it, am getting error found "no DATA".
  
  Please advice if I use FORALL and EXECUTE IMMEDIATE on a SELECT statement?
  
  I can share the scenario...
  
  Thank you!

  Hello

  a few notes.

  1. to_date(t2.time_id,'dd-mon-yyyy')

  New York T2.Time_ID Cis the varchar2 data type that contains values to JJ-me-YYYY format?

  And if, in which language is used for the names of the months? Conversions are point impossible to solve in reasonable time limits without logging of dml errors and unique failure on charges of staging nightly!

  You can use Q or q to escape single quotes in strings.

  3. validation

  Not required because the DDL commands commit implied.

  In general I recommend you write commit clauses only in calling script rather than in the code unless it connects with an autonomous transaction.

  You end up with a lot of validation of code here and there and you don't know where it is and where it isn't. That is, your process may have more than one appeal process and commit the middle of the process, it is not atomic processes.

  Here's the demo although I recommend also using the static table and truncate to efficiency. ETG is good choice for the purpose of maintenance table.

• Storing the values of execute immediate instruction.

  Hi all
  I execute immediate statement that gets several rows at a time. I need to save this picture and print. Pleas elte the syntax me to use an array or temp table in oracle. See the code provided below.
  Thank you...
  declare
  v_ct varchar2 (290);
  v_sqlcode number: = 0;
  v_stmt varchar2 (2900);
  r_tbl VARCHAR2 (150);
  cursor c_tbl is
  Select the table TABLE_NAME from DBA_TABLES where OWNER = 'ted '.
  Start
  Open c_tbl;
  loop
  extract the c_tbl in r_tbl;
  When the output c_tbl % notfound;
  v_stmt: = 'select NULLABLE from DBA_TAB_COLUMNS WHERE TABLE_NAME =' | " ' || r_tbl | " ' |' and COLUMN_NAME in (select column_name from DBA_IND_COLUMNS where INDEX_NAME = (select 'INDEX_NAME' from DBA_INDEXES where TABLE_NAME =' | ")) ' || r_tbl | " ((' |' and UNIQUENESS = "UNIQUE"))';
  run immediately v_stmt in v_ct;
  v_sqlcode: = SQLCODE;
  If v_sqlcode = 0
  then dbms_output.put_line (v_ct);
  end if;
  end loop;
  close c_tbl;
  end;

  Your immediate question seems to be answered.

  I would like to point out a few problems with your code, however.

  First of all, it seems pointless to use dynamic SQL here - you can use a static SQL statement to get the same data. You can use static SQL, you should.

  Secondly, if you want to use dynamic SQL statements, you should really use bind variables. Something like

    v_stmt := 'select NULLABLE from DBA_TAB_COLUMNS WHERE TABLE_NAME = :1 and COLUMN_NAME in (select column_name from DBA_IND_COLUMNS where INDEX_NAME= (select "INDEX_NAME" from DBA_INDEXES where TABLE_NAME =':2 and UNIQUENESS =''UNIQUE''))';
    execute immediate v_stmt
        bulk collect into v_ct
      using r_tbl, r_tbl;
  

  Third, your deepest query is to select the literal 'INDEX_NAME' rather than the name of the actual index. Unless you happen to have an index named INDEX_NAME, who is likely to be a mistake.

    v_stmt := 'select NULLABLE from DBA_TAB_COLUMNS WHERE TABLE_NAME = :1 and COLUMN_NAME in (select column_name from DBA_IND_COLUMNS where INDEX_NAME= (select INDEX_NAME from DBA_INDEXES where TABLE_NAME =':2 and UNIQUENESS =''UNIQUE''))';
    execute immediate v_stmt
        bulk collect into v_ct
      using r_tbl, r_tbl;
  

  Fourth, unless you can be sure that the table has a unique index, your query will return an error because the deepest returns multiple lines.

    v_stmt := 'select NULLABLE from DBA_TAB_COLUMNS WHERE TABLE_NAME = :1 and COLUMN_NAME in (select column_name from DBA_IND_COLUMNS where INDEX_NAME in (select INDEX_NAME from DBA_INDEXES where TABLE_NAME =':2 and UNIQUENESS =''UNIQUE''))';
    execute immediate v_stmt
        bulk collect into v_ct
      using r_tbl, r_tbl;

• ORA-01031 on create sequence with Execute Immediate

  I have the following statement in a procedure:

  EXECUTE IMMEDIATE
    ' CREATE SEQUENCE my_seq
      INCREMENT BY 1
      START WITH 130224
      NOMINVALUE
      NOMAXVALUE

  When the statement is executed, I get an ORA-01031: insufficient privileges error.
  
  I can run the CREATE statement in sqlplus. The schema from which I executed the CREATE statement is the same as that under which the procedure is run. In addition, the procedure is also created in the same schema.
  
  What a privilege I'm missing?

  Your privilege CREATE SEQUENCE given to you through a role.

  Roles are not considered in the stored procedures, you must have the privilege granted directly to your user name.

• EXECUTE IMMEDIATE or DBMS_UTILITY. EXEC_DDL_STATEMENT

  Hello
  
  I recently became aware of DBMS_UTILITY. EXEC_DDL_STATEMENT and I was wondering if it works in pretty much the same way as EXECUTE IMMEDIATE. I'm guessing that EXECUtE IMMEDIATE offers more flexibility when putting together the command you want to run, but you are the only real difference? All opinions accepted with gratitude,
  
  Kind regards
  
  Kevin.

  This isn't an exact answer to your question, but it may be useful.

  Execute Immediate is the approach privileged 9i or higher. If you decide which to use, go with EXECUTE IMMEDIATE. You never know when the other dynamic SQL methods will be deprecated. In addition, EXECUTE IMMEDIATE has also been optimized (and will continue to be optimized), so you can usually expect better performance during use.

  The exact differences between EXECUTE IMMEDIATE and DBMS_UTILITY. EXEC_DDL_STATEMENT go, I can't give you an exact answer. (Also the fact that DBMS_UTILITY. EXEC_DDL_STATEMENT DDL is, of course).

  You may or may not find this article helpful: http://okjsp.pe.kr/seq/9789. He did a good job to compare the differences between EXECUTE IMMEDIATE and another way inherited to the dynamic SQL statements (DBMS_SQL. RUN)

• Execute Immediate is not working well

  We need to find tables with the same name and columns but these columns whose data type is different. The SQL below detects the difference.
  

  select a.table_name, a.column_name, 
  a.data_type ||'---> '||a.owner BASE_SCHEMA_TYPE, 
  b.data_type ||'---> '||B.owner COMPARED_SCHEMA_TYPE 
  from all_tab_columns a, all_tab_columns b  where a.owner =
  'SCOTT' and b.owner = 'HR'  and a.table_name=b.table_name and
  a.column_name=b.column_name and a.data_type!=b.data_type

  Based on the SQL above, I created the procedure mentioned below which takes a base as input parameter schema and find these tables with the same name but have different data type columns. It generates dynamic SQL code properly (you can see in DBMS_OUTPUT) but for some reason, the INSERT is not the case with EXECUTE IMMEDIATE. No idea why?
  

  create or replace procedure admin.compare_data_types (p_baseschema in varchar2)
  is
  v_sql   varchar2(2000);
  begin
  
  delete from admin.differences;
  commit;
  
  for rec in (select  username from  dba_users where Username IN ( 'HR'))
  loop
  
    v_sql := 'insert into admin.differences select a.table_name, a.column_name, a.data_type ||''---> ''||a.owner BASE_SCHEMA_TYPE, b.data_type ||''---> ''||B.owner COMPARED_SCHEMA_TYPE from all_tab_columns a, all_tab_columns b      where a.owner = '''||p_baseschema||''' and b.owner = '''||rec.username||'''  and a.table_name=b.table_name and a.column_name=b.column_name and a.data_type!=b.data_type';
       
       dbms_output.put_line (v_sql);
       execute immediate v_sql;
       --commit; -- Doesn't make any difference
       --v_sql := null; -- Doesn't make any difference
       
  
  
  end loop;
  commit;
  
  end compare_data_types;

  Structure of the table being INSERT ed

  create table admin.DIFFERENCES
  (
    TABLE_NAME           VARCHAR2(200),
    COLUMN_NAME          VARCHAR2(200),
    BASE_SCHEMA_TYPE     VARCHAR2(100),
    COMPARED_SCHEMA_TYPE VARCHAR2(100)
  )

  How about putting in a debug message to see what he does...

  (don't forget to ' set serveroutput we "before...)

  create or replace procedure admin.compare_data_types (p_baseschema in varchar2)
  is
  v_sql   varchar2(2000);
  begin
  
  delete from admin.differences;
  commit;
  
  for rec in (select  username from  dba_users where Username IN ( 'HR'))
  loop
  
  insert into admin.differences
  select a.table_name
        ,a.column_name
        ,a.data_type ||'---> '||a.owner BASE_SCHEMA_TYPE
        ,b.data_type ||'---> '||B.owner COMPARED_SCHEMA_TYPE
    from all_tab_columns a
        ,all_tab_columns b
   where a.owner          = p_baseschema  -- Procedure Paramater
     and b.owner          = rec.username
     and a.table_name     = b.table_name
     and a.column_name    = b.column_name
     and a.data_type!=b.data_type;
  
   dbms_output.put_line('Rows Inserted for '||rec.username||': '||sql%rowcount);
  end loop;
  commit;
  
  end compare_data_types;
  

  And see if it is one) enter the loop and b) the number of rows is inserted during the process.

  If it displays 0 rows inserted, then there's something of logically wrong with your select statement, as is return nothing.

  You have extra quote (marked in red). But remove won't solve all of your problems. EXECUTE IMMEDIATE executes a SQL statement. You must divide in two strSQL:

  strSQL:=' CREATE UNIQUE INDEX "WEBDBTARGET"."PK_EMPID6" ON "WEBDBTARGET"."EMP_R1" ("EMPID")
  PCTFREE 10 INITRANS 2 MAXTRANS 255 COMPUTE STATISTICS

  PCTINCREASE 0 FREELISTS 1 FREELIST GROUPS 1 BUFFER_POOL DEFAULT)
  TABLESPACE "TARGET_TS_01"';
  EXECUTE IMMEDIATE strSQL;

  P.S. in the majority of cases it IT not a good design of database to create objects dynamically.

• dml execution 2 statements at a time with the help of execute immediate

  I would like to run 2 DML statements at a time with the help of execute immediate usefulness,.
  
  ex:
  
  update employee set ename = 'Chantal' where eno = 123;
  Update dept set dname = 'IT' where dno = 345;
  
  I want the two statement to execute at a time, but I don't want to use any loop as well.
  
  Thanks in advance

  You can use:

  execute immediate 'begin update employee set ename='jagadeesh' where eno=123; update dept set dname='IT' where dno=345; end;';
  

  Although updates will always run one after the other.

  If you want the simultaneous treatment, then you need to use DBMS_JOB and DBMS_SCHEDULER to plan both work to run to run each of the statements independently.

• Open FPGA references change to no. target when compiled with executable in time real start

  Hello again you useful forum fans!  I have a problem that I hope someone can give me a hand with.

  I have a project that has a Windows component and a component of the target in real time, that are running on a hypervisor type NI PXI-8110 system.  Communication both sides between them using shared variables.

  On the real-time side, I have four FPGA targets who are reading and writing various analog and discrete inputs and outputs.  I several periods loops which opens a reference to one of the FPGA targets during the first call, then pass this reference in several subVIs that read and write to panels prior to the FPGA.  The loops the FPGA reference thus made available and reuse it in the next iteration through the shift registers.  Each FPGA target has only a single reference open to him.  One of the loops is using the FPGA reference directly and does not pass it in any subVIs.

  It all works very well in the development environment, I can read and control inputs and outputs FPGAS via the front panel of the application of the side Windows.  It also works very well if I start the game real time in the development environment, and run the code of windows as a stand-alone executable file.

  However, when I compile the code in real-time in an executable startup and deploy it to the target, it does not work.  I enabled debugging on the executable, and when I connect to it via the operation-> debug executable in the menu, I see an arrow broken at execution.  Further investigation shows that each of the four open screw reference FPGA is now empty, the text under them is "no target" and the thread for reference on their part to my first Subvi is broken.  I need your help to understand how to operate as it does in the development environment.

  I followed the instructions of these two knowledge base articles to compile and download the bitfiles FPGA on the FPGA target and execute on start or restart:

  Open FPGA reference screw are configured for the FPGA to build specifications that I created for each target in the LabVIEW FPGA project.

  I called technical support, NO phone, and yet were able to determine this one out, so additional "brownie" points if you do!  I would offer you the same no detailed screenshot that I have (I can't give more detailed code out because its owner, unfortunately), but apparently the forum doesn't like my image file, as I can't seem to load.

  Please let me know if you have any ideas regarding what is happening!  I appreciate it.

  Jon,

  I'm always up for the challenge.  Have you tryied recompile the FPGA VI that accesses the RT VI?  I also suggest to try and open the bitfile instead of the FPGA VI.  You run in dynamic mode (this is not a suggestion, it's just a question)? There is no difference if you try to open the FPGA VI reference outside the while loop, then past the reference to use inside the while loop without shift registers, then close the reference to the FPGA VI outside the while loop?

  Let me know if these suggestions makes no difference.

• use of the server for executable files VI

  Hi all

  I tried to find a good explanation and example usage of VIserver to launch executables on client PC (XP) via a LAN to a PC (Win7) process controller. Basically, what I found for the controller is specified in this code snippet:

  

  The following was placed in the .ini file of the target at the time of construction to allow VIserver using an executable file (?):

  Server.TCP.Enabled = True
  Server.TCP.Access = "' + * '"
  Server.TCP.port = 3364
  Server.TCP.ACL = "290000000A000000010000001D00000003000000010000002A10000000030000000000010000000000"
  Server.VI.Access =""
  server.vi.callsEnabled = True
  server.vi.propertiesEnabled = True

  If a reference to an instance of application LV is open on the computer command on a specified port, and then a VI reference target

  for the .vi file (another instance?) opens on the same target for manipulation of knot VI. So what was lost for me is the executable

  I am trying to run the file. May not be wired to the terminal way to "ref Open VI". This implementation requires the .exe version and the version of VI

  I am trying to run the code? I launched with success of executable files over a LAN using plink with a script file. Problem is that I can't find a way

  get the target executables once loaded. There is most likely a C solution for this (I'll take it if anyone knows!), but since has VIserver of tools

  to control the execution, I would use it. Also, I want to understand the version of VI of the programme and the .exe in this case (s) link

  Version. Any help would be greatly appreciated.

  Ben OK,

  Your messages made me a technique to load with distance and running an exe file, built in LV8.5:

  1. to load: the controller emits a "tasklist" command to a target. The objective produces an output file of tasklist which is read by the controller. If it concludes that the target is already loaded, the controller will execute it with an invoke command node 'run a VI '.

  2. If the target is not loaded, then a script file is executed on the target via plink of the controller. This command will also start running.

  3. all the subVIs must reside on the target, as you said, even if (as in my case), the target has no LV Developer Suite installed. I placed Traoré versions of files and folders to exe in the same folder.

  4. the .ini file in the compilation has changed as shown in the first post of this thread. No special settings were used in the compilation.

  This probably isn't the exact technique you had in mind, but it doesn't seem to work... Thanks again for your help.

• This VI belongs to a class of LabVIEW. No part of the class is executable at this time, because one of the screws is missing. However, I'm not missing a vi

  I have only 1 vi and its not to miss.  1 vi advertising the library owner has blocked enforcement of the VI.  The class has the error "this VI belongs to a class of LabVIEW. No part of the class is executable at this time, because one of the screws is missing. Find Member missing screws on the disk and load them into memory or remove them from the definition of class in the project tree. »

  But there is only 1 member vi! ??

  I had a lot of other vi through this class, but somehow this class failed with this error.  I removed all vi directory and the definition of class and just done re the a vi reviewer and still have the error message.

  I enclose my ridiculously simple class.

  I have other classes that work very well, but somehow it seems to have gotten sloppy.  I really need to understand what happened here and how get/avoid this error, or I wouldn't have the confidence to develop large scale applications using classes.

  In other words... Help, please!

  Your class contains two screws a VI is called Untitled 1 and the other reading Max level.vi.

  Maybe this could happen (not tested) as follows. You have created two screws and saved one of them as reading Max level.vi. Then, you have saved the class. When the classyou of fence chose not to save untitled 1 and not to save the class.

  How to fix it. Open the class file with any text editor. Remove all lines between and including the following lines in the file:

  
     

  This will fix your class.
