• Get the EXIT and the RETURN of a stored procedure parameters

  I have a stored procedure (SQL Server 2008 R2 MS) as in the following example.

  Thanks to the connectivity of database I get OUTPUT parameters, but I can't get the game DATA RECORDS and RETURN value.

  Someone knows how to do this?

  CREATE PROCEDURE [dbo]. [TS_Teste] (@T057_S_NOMEMAQUINA VARCHAR (20), @STATUS INT OUTPUT, OUTPUT OF NVARCHAR (500) OF @ERRO)

  AS

  BEGIN
  DECLARE THE TABLE @TABLE (CODE INT, DESCRIPTION VARCHAR (30))

  INSERT VALUES INTO @TABLE (51, 'A')
  INSERT VALUES INTO @TABLE (52, 'B')

  INSERT VALUES INTO @TABLE (53, 'C')

  SELECT * FROM @TABLE

  SET @STATUS = 1

  SET @ERRO = "Nenhum erro!

  RETURN 0

  END

  I finally found what was wrong... He had a line in the stored procedure only aditional. It should be like this:

  CREATE PROCEDURE [dbo]. [TS_Teste] (@T057_S_NOMEMAQUINA VARCHAR (20), @STATUS INT OUTPUT, OUTPUT OF NVARCHAR (500) OF @ERRO)

  AS

  BEGIN
  SET NOCOUNT ON;                                                                                               -NEW LINE!

  What is important, what I'm trying to do is to NOCOPY the BLOBs. Otherwise, I have to read my PDF files into 2 BLOBs and create a 3rd blob as output. I prefer to be able to keep the pio_pdf2append2 as the final output. What I actually do call thing in a loop to gradually add a PDF file to a big. I'm not linking this in one operation because of concerns over the use of the system and because the pdfbox library java has would have been question after 850 in PDF format, which is not completely unrealistic in my approach.

  How could I achieve this?

• SQL stored procedure input and output parameters

  Hello Gang,

  My dead end trying to call a stored procedure in SQL Server 2008 with the LV database tool.

  for purposes of experimentation, I've created a small procedure with an input parameter that returns an integer as return value.  It works describing a query, but all attempts at LV produce an error-2147217900 when executing query VI.  I did find examples of that.

  Sending a bunch of parameters to a stored procedure and checking the value of return seems to be pretty common stuff.

  I'll appreciate any help.

  Thank you

  Roger

  Hi Roger,

  There are a few prerequisites which I will list below. If you have not checked these things, so don't hesitate, as your hiccups can be there.

  Prerequisites:

  1. Ensure that you can read from a table in the database to verify that you can access the database (user permissions) and ensure that your login details are correct. Among other things, make sure that the. DSN switches to the correct database. (See the simple example below, SQL Select.vi)
     
  2. Make sure that your user (if you use SQL authentication) has permissions to run the STORED procedure by running the procedure in SQL Server Management Studio (you seem to have already done this)

  Example by calling a procedure without parameters (attached as SPROC_No_Parameters.vi):

  

  Example by calling a procedure with parameters (attached as SPROC_Parameters.vi):

  

  An article on the execution of stored procedures is here:

  http://digital.NI.com/public.nsf/allkb/07FD130746083E0686257300006326C4

  Don't forget to download the example VI since it includes the cases where you want an output parameter of the procedure rather than a table.

  I tested these against two very simple SPROCs and it worked fine (on SQL Server 2005, but 2008 should be the same).  Stored procedures have been:

  CREATE PROCEDURE [dbo]. [GetContacts]

  AS
  BEGIN
  -SET NOCOUNT ON added to avoid additional results sets from
  -interfering with SELECT statements.
  SET NOCOUNT ON;

  -Controls insert for procedure here
  SELECT * FROM Contacts
  END

  and

  CREATE PROCEDURE [dbo]. [MultiplyAges]
  @param1 INT = 1
  AS
  BEGIN
  -SET NOCOUNT ON added to avoid additional results sets from
  -interfering with SELECT statements.
  SET NOCOUNT ON;

  -Controls insert for procedure here
  SELECT (age * @param1) OF Contacts
  END

  I would like to know if these examples work for you or if you have any other questions.  Don't forget to go through this KB article and articles related to it, they should cover other situations.

• Calling stored procedures with parameters with the database connectivity Toolkit

  Hi all

  I'm new to the forum and struggling to find a solution to a particular problem I have in this respect, using the LabVIEW Database Connectivity Toolkit on a project, I am currently working on my work.  I have a database in which I tables and stored procedures with parameters.  Some of these stored procedures have input, output and return parameters.

  I tried to follow this example, but to no avail: http://digital.ni.com/public.nsf/allkb/07FD130746083E0686257300006326C4?OpenDocument

  Such a stored procedure I am working on the implementation is named "dbo.getAllowablePNs", running "SELECT * from DeviceType" (DeviceType is the table).  In this case, it requires no input parameter, it has an output parameter that generates the table [cluster] and has a return parameter that returns an integer value (status code for execution) to show if an error occurred.  The DeviceType table has 3 columns; ID (PK, int not null), PN (nvarchar ((15), null) and NumMACAddresses (int, null).)  I have surpassed many examples and I talk to the support OR try to implement this and similar procedures stored in LabVIEW but have not been successful.  I am able to connect to the database with the VI of open connection without error, but spin in some confusion as a result of this step.  I then try to use the VI of parameter query create to call the stored procedure and set the parameters.  I guess I would then use the Set parameter value for each parameter that is connected to the entry of parameters on the previous query with parameters VI VI?  I am also having some confusion during and after these steps as well.  I would greatly appreciate advice or suggestions that anyone could have in this situation because I am not a SQL expert.  Also, I would be happy to provide more information that might be useful.

  Kind regards

  Jon

  Here's what I use to do this.  I think I had to change him create parameterized query VI for him to work.  There is a post on the forum about this somewhere.

• Call the stored procedure, and bind parameters by name

  Hello

  I use the Oracle ODBC 12 c driver to pass values from one Interface to our database Oracle 11.2. The Interface software collects data from modbus protocoll and calls a stored procedure. Right now my syntax to call the stored procedure looks like this:

  CALL procedure-name ('STRING', 'Timestamp as String', numValue1);

  It works very well. Now, I have to add a default setting to my procedure. To stay flexible to make other changes, I want to call the procedure and bind the parameters by name. Release 10.2.0.1.0 ISC ODBC Notes:

  Added support for the named parameter, binding the parameters by name. ODBC Oracle driver now allows the application to specify the parameters of a stored procedure by name, in the procedure call. Named parameters are to be used in calls to stored procedures and should not be used in other SQL statements.

  So, it shouldn't be a problem to use named notation, but how do I do this in ODBC? I tried like this, but oracle returns an ora-00936 error of missing expression:

  call procedure-name (paramName1 = > 'STRING',= paramName2 > 'Timestamp as String',paramName3 = > numValue1).

  
  

  Thank you for your help.

  Finally, I was able to find the error. The syntax of the statement was very good. The problem was caused by another declaration that I edited before and the error has not attracted Attention immediately.

  Thanks for reading and looking for an answer.

• What are the ways to access a remote database in a database completely different-schema - stored procedure?

  My source data in the remote database schema (say C3.case). And I am trying to insert data of this CASE table in my database table (for example SIMS.case) I use the stored procedure to load the data.

  I was going through the documentation and I thought that the creation of MV is not possible in this case is the source table in the remote database schema. Is this correct?

  or create a link DB is the only option available to access the remote database schema table.

  Thank you.

  Hello

  2929538 wrote:

  My apologies for the bad conventions help. I meant remote schema.

  the required data and the destination table, the two are in oracle, but in totally different schemas.

  Yes, you said a table is in a scheme called C3, and the other is in a schema called SIMS.  Are these schemas in the same database or in different databases?

  If they are in the same database, then you do not have a database link.  Or the other schema can reference tables in the other qualifying names correctly, for example

  SELECT *.

  OF C3. case_studies

  ...

  assuming that the right privileges have been granted.

  If the schemas are in different databases, a database link is the best way to access data in a database in a different database.

  Without a database link, you will probably use some kind of use outside the database to write the data to a database, the file if necessary, transport and read in other databases.  DataPump files of images or CSV files, as Paulzip said in answer to #1, could be used for this.

• Access to the defined user compex types in stored procedure

  Hi all

  Since MA_DATABASE_TABLE is a collection, you must tell Oracle item on which you want to:

  For example, if you want only one element in the collection:

  TMP_DB_NAME: = MSACCESSCOLL. DATABASECOLL (1). DB_NAME;

  otherwise, you will need to loop.

• [BC] Call a stored procedure taking parameters of table

  Hello!

  I currently have a request of the OIC that makes thousands of calls per second stored procedure. The stored procedure runs a business logic that I want my client application to stay informed.  I want to reduce the cat of the database and instead to call the stored procedure from thousands of times per second, call the procedure (for example) once per second, but with values of one mile.

  I used OCIBindArrayOfStruct successfully to perform inserts bulk, where my OCI application executes a () INSERT INTO using the function "iters" and it might be possible to do something similar with the stored procedure, but I want to do something slightly different, because the procedure stored something like this:

  * If a specific condition is set, call a secondary stored procedure

  * If another special condition is set, insert a row into a table of some

  I so wanted to do was to pass a table (or a series of tables) in the stored procedure, then the stored procedure to use optimal methods that are available, such as FORALL, to perform each of the tasks, the more effectively.

  So I thought to create a type, such as a TABLE OF VARCHAR2, or a VARRAY and possessing of the parameters for the stored procedure based on this type, something like:

  create or replace TYPE 'NTT_VARCHAR2' AS TABLE OF VARCHAR2 (32700);

  create or replace FUNCTION bulk_process_values)

  p_error_message OUT NOCOPY VARCHAR2,

  p_module_context_name OUT NOCOPY VARCHAR2,

  p_sql_error OUT NOCOPY VARCHAR2,

  p_count in NUMBERS

  p_non_array_var_1 IN VARCHAR2,

  p_non_array_var_2 IN VARCHAR2,

  p_array_var_1 IN NTT_VARCHAR2,

  p_array_var_2 IN NTT_VARCHAR2,

  p_array_var_3 IN NTT_VARCHAR2

  < etc. for all the variables in table >)

  RETURN NUMBER

  .. .but I am struggling to find an example of how call the procedure "bulk_process_values" stored, and even if I use a TABLE OF VARCHAR2 or a VARRAY as a parameter type.

  I searched the Internet and found this: OIC - how to bind an array to a stored procedure? - and binding table of the structs (OCIBindArrayOfStruct) sample code

  - but they take different approaches and a bit confused (the second example spoke of OTT).

  I think that the first approach is more likely to be the solution I need - but I can't help thinking - it is a bunch of stuff to move if it does not end up significantly improve performance!

  My questions are:

  * Moves to a call-SP-thousands-of-times-per-second to call-SP-fewer-times-but-with-array-parameters sensitive?

  * Should the table or VARRAY, TABLE OF VARCHAR2 parameters or something else?

  * Should I use for my case OTT?

  Samples I found are both very old - and the second example indicators that the optimal approach evolves with the OCI versions - I'm on 11.2, what is the optimal approach these days?

  * < added later > why is there no official useful example?

  Thank you very much

  Much appreciated. https://community.oracle.com/message/4528528#4528528 has actually worked, with VARRAY, with a proof of concept. Now I just need to shake a little and then get my PL/SQL for optimal PC experts. I think I was really discouraged by the lack of official documents, with the Community (Paradise) is the only way to get real results.

  Thank you JJ.

  I intend me to use the binding enforcement of the table and the table and avoid N back and forth, but I do not then get the opportunity to do something clever in the PL/SQL.

  In the PL/SQL, there is no logic occurring - I don't call the same SP tons of times, but then I want to be able to use PL/SQL optimizations such as FORALL, BULK COLLECT, reduce the number of validations and others.  There is a commit after each SP run, because otherwise the nature of demand means that the application hangs occur; However, there is a way (I think) be smart on the part that is likely to deadlock (making a shape on the Bay First, then applying the updates in the order sorted and then failed to get a blocking theoretically), and then FORALL insert for the second part of the stored procedure.

  I guess I may apply the single return, passing a table (to a commit in the SP)-which will reduce back and forth, so gain in performance, but it will not reduce the number of validations that I do - and Oracle said that commits too frequent is not good for performance. I already have code in my framework that does - by making a simple INSERT INTO.

  Good to hear that OTT is not explicitly required - and VARRAY resembles the approach to try first.

• setting report parameters fails for the report that runs the stored procedure in QMR FDM 2.1.1

  Hello

  Can someone help us please on this issue we have; If a solution is already available somewhere on the forum please link me to it.

  Please see our situation;

  The script below was part of the customization of a colleague to a script of Oracle FDM ("AftFileImport").

  There are no screenshots at this stage that came back to us with a temporary workaround.

  More detailed description:

  We built a custom report of FDM ("FSBValidationErrorsforAllLocations") that accepts two parameters (CatKey, period) and which calls a procedure stored in SQL Server with the same two parameters. FDM SQL statement of the report is:

  RUN FSBValidationErrorsforAllLocations ' ~ time ~', ~ Cat Key ~

  It works through the User Interface.

  When you try to put the two settings by customizing the event Oracle 'AftFileImport'script, the report fails. Below the part of the code in the 'AftFileImport', where we tried to fill values:

  • objReport.mParametersClear
  • objReport.mParametersAddNew "CatKey", RES. PstrCat
  • objReport.mParametersAddNew 'Period', RES. PstrPer

  We must understand why the way above to the definition of the parameters does not work with stored procedures, as seems to be the only documented way Oracle of setting parameters.

  Please let me know if that's enough.

  
  

  Thank you in advance.
  

  Hello

  which is the error when you run the script?

  • objReport.mParametersAddNew "Cat Key", RES. PstrCat

  Try again with the white space as it is how you named your parameter in the report definition, didn t you?

  Also try to use the built like the following examples:

  	objRP.mParametersClear
  	objRP.mParametersAddNew 'Period', CDate (dtePeriod)
  	objRP.mParametersAddNew 'Loc', CLng (lngLocation)

• Maximum number of parameters sent to the stored procedure

  I have a web form where I insert data in Oracle. There are at least 20 fields on the form. For the INSERT, I want to use the stored procedure. But in this case for the section of the VALUES in the INSERT statement, I need to send that many - in this case 20 settings. Is it normal for a procedure to receive 20 parameters? If this isn't the case, then should how I follow to do? I know that technically there is only no problem but isn't normal programming or database managementwise? I think it's the basic thing any developer web do it all the time.

  Is it normal for a procedure to receive 20 parameters?

  Sure. It is very good.

  But what is normal programming or database managementwise

  If you need to insert values for 20 fields then normal.
