• CallFunction return type of the object instead of boolean

  Hello

  I used getScript("Somescriptname").callFunction to call a function in another script which has a boolean as a return type.

  The call above always returns type object, I tried an explicit cast to a boolean, but his throw syntax error.

  Please suggest

  Thanks and greetings

  Hello Suresh,

  getScript (.callFunction) always returns an object.  Initially, it should be stored in an object and then analyze Boolean value as shown below:

  Object Val = getScript("ScriptName").callFunction ("FunctionName", past of the arguments for the function, if any);

  Analyze as below

  Giveme Boolean = Boolean.parseBoolean (val.toString ());

  System.out.println ("return val:" + giveme);

  This should solve your problem.  Please let me know if this isn't...

  A happy test...

• DatabaseProcedure with the return type preceded of the schema name

  Salvation (Paco)
  
  I have a question on the DatabaseProcedure class. We use proxy Oracle users to our database connections.
  Everything is accessible via a role of database that are granted to the user. All of our database objects, tables, etc. are protected by this database role.
  When I want to call a function/procedure of database, I need to add the name of the schema as a prefix to the custom database object that uses us for parameters and return types.
  
  So far so good. I can also define a parameter prefixed by the name of schema via the DatabaseProcedure.registerArrayType...
  But when I try to set a function call that uses this parameter I get an error saying "the statement is not valid.
  The problem is the regular pattern of PROCEDURE_DEFINITION:
  

  private static final Pattern PROCEDURE_DEFINITION = Pattern.compile("\\s* (FUNCTION|PROCEDURE) \\s+ ([\\w.$]+) \\s* (?:\\((.*?)\\))? \\s* (?:RETURN\\s+(\\w+))? \\s* ;? \\s*", CASE_INSENSITIVE | COMMENTS | DOTALL);

  The return type cannot be prefixed by the name of schema.
  
  Any good suggestions or workarounds?
  
  I have actually change the duration of reflection model to make it work-, but I really don't like this solution over the long term.

  Hi Torben,

  I think that I have a work around for the problem which might work for you. If you look at the source of DatabaseProcedure.registerArrayType you will find that it is actually called DatabaseProcedure.registerCustomParamType.

  public static void registerArrayType(String name)
  {
    registerCustomParamType(name, Types.ARRAY, Array.getORADataFactory(), name);
  }
  

  A solution you can replace calls to DatabaseProcedure.registerArrayType with calls to DatabaseProcedure.registerCustomParamType as follows.

  // Instead of DatabaseProcedure.registerArrayType("NAME.WITH.DOTS") call:
  DatabaseProcedure.registerCustomParamType("anyNameWithoutDots", Types.ARRAY, Array.getORADataFactory(), "NAME.WITH.DOTS"); // Don't forget to use uppercase here.
  
  DatabaseProcedure dp = DatabaseProcedure.define("procedure my.procedure(param1 in out anyNameWithoutDots)");
  
  DatabaseProcedure.ParamType type = dp.getParamDef(0).getType();
  System.out.println(type.getName() + " is " + type.getTypeName()); // ANYNAMEWITHOUTDOTS is NAME.WITH.DOTS
  

  In this way, that you don't have to use the 'illegal' name in the definition of DatabaseProcedure.

• Updating of the Data Services loses configured enter/return types

  v 4.0.1

  I have several configured data services (all PHP services).  I have about 20-25 functions defined in all 6 services, but 4 functions will surely lose the enter/return types configured each time a manual refresh or auto data occurs.  For example, I have a function:

  saveOrder(OrderHeader:Object,_LineItems:Object):Object

  When I right click and 'configure the Types of entry... '. ", and then"configure return Type... ". "I can set the appropriate without any error types.  I get so I expect the function definition:

  saveOrder(OrderHeader:OrderHeaderFlex,_LineItems:LineItemFlex[]):Boolean

  My ACE and PHP code seem to have errors, I've tested successfully this function repeatedly.  However, if I right-click and choose "Refresh" on my name of service or the service itself, the function returns the definition of the unknown.  He will go even after the automatic update, which produces from time to time.  I can configure the types of data and then immediately, click Refresh and this function will return to the unknown, even if there has been absolutely no code changes.  I have other services and functions in the same project (some that use the same types of data involved above) who do not have this behavior.

  Even when these functions "lose" data type configuration, my project will still compile and affected functions will work as expected.

  This occurs because of a bug in Zend. See the bug related to FB and the bug of zend.

• Doubt about the return type of function

  Hello
  
  Can a function returns a Boolean value in a select query.
  
  Suppose m creating a function... so can we have a return type of Boolean as...?
  
  If so... THN please give an example

  Can a function returns a Boolean value in a select query

  The answer is no. a Boolean is not a SQL data type and may not be used in the SELECT query.
  For the user-defined function to be called in a SQL statement, see http://download.oracle.com/docs/cd/E11882_01/appdev.112/e10471/adfns_packages.htm#ADFNS00908
  Note especially these lines

  "Its formal parameters and its return value (if any) must have built-in data types (for example, CHAR, DATE or NUMBER) Oracle, not types (such as BOOLEAN, RECORD or TABLE) PL/SQL data.

  "There is an exception to this rule: a formal parameter can have a PL/SQL data type, if the corresponding actual parameter is implicitly converted to the data type of the formal parameter" >

• Function to check a tree with Boolean return

  Hello
  
  I have the problem that I need a validation on a tree table which checks if the changed tree node is part of its own sub-nodes.
  
  Example of DDL:
  
  CREATE TABLE 'TREE_SYSTEMS '.
  (SELECT 'S_ID' NUMBER NOT NULL,)
  ACTIVATE THE 'S_NAME"VARCHAR2 (100) NOT NULL,
  ALLOW "S_PARENT" NUMBER NOT NULL
  )
  
  Example DML:
  
  1, 1, pc systems
  2, personal computer, 1
  3, server, 1
  4, motherboard, 2
  5, ram, 4
  6, cpu, 4
  7, HDD, 4
  8, backup to disk, 7
  
  Now the parent of id = 2 key changes from 1 to 8.
  I want to have a function that takes a true or false value if the operation is allowed. In my example, the 'personal computer' would be part of its own node "backup to disk". This is not allowed (false).
  
  The real tree can have x subnodes. Perhaps there are examples on how to do it?

  Oracle Forms/Reports has a complete PL/SQL engine and (only) the SQL parser.

  However, the engine of forms/States PL / SQL and SQL Analyzer are at a level that was in the Oracle 8.0 database.

  So, in the forms/States functions/procedures and forms/States triggers, you can not use SQL commands that did not exist in the 8.0 database.

  The predefined SYS_REFCURSOR type is introduced in Oracle 9i.

  Use this:

  PACKAGE test_rc IS

• Property Finder have table as return type

  Hi all

  Is it possible to return the finders of vco table types?

  If I give the property name in the property-bean attribute then it gives [Ljava.lang.String;@4981086 as value (as expected).

  < bean-PROPERTY = display name "testProp" = "Property of Test" hidden = "false" name = "testProp" show in the column = see "real" description = "true" / >

  But is it possible to specify bean-property attribute of tag finder so that we can wrap up the property value according to a static utility method. Maybe something like below (I know that the threshold is not correct, but it's just a wild guess)

  < bean-property = "StringUtils.joinArray (testProp) property' display name ="Test well"hidden ="false"name ="testProp"show in the column = see"real"description ="true"/ >"

  Or any other means by which I can manage property array return types.

  Thank you for your help.

  Best regards

• RETURN type of function table

  Hello

  I read conflicting information about the return type that has a table function must or may use.

  First, I am a student of a book that says:

  Function in pipeline returns the data types:

  The main constraint for the pipeline functions, it is the return type must be a collection type autonomous which can be used in SQL - i.e. a VARRAY or table nested.

  and then in the next sentence...

  More precisely a pipeline function can return the following:

  A stand-alone nested table or VARRAY, defined at the schema level.

  A nested table or VARRAY that has been declared in a package type.

  This seems to go against the first quoted sentence.

  Now, before reading the above text I had done just my own test to see if a packed type would work because I thought I had read somewhere that it would not, and he does not (the test code and this output is at the end of this question). When I arrived in the text above, after my test, so I was naturally confused.

  So, I'm going to PL/SQL reference that says:

  RETURN data type

  The data type of the value returned by a function table in pipeline must be a type collection defined either at the level of schema or within a package (therefore, it cannot be a type of associative array).

  I tried to call a function that returns a collection of VARRAY type packaged in both SQL and PL/SQL (of course below is SQL all in any case) and no work.

  Now I'm wondering what is a TABLE function must use a schema type and a function table in pipeline can use a packaged type?  I see that I created and called a function table but examples of Oracle see the creation and use of a function table in pipeline.

  Edit: I should add that I read the following sentence in the SF book on p609 in * table functions: "this type of nested table must be defined as an element of level diagram, because the SQL engine must be able to resolve a reference to a collection of this kind."

  So that it begins to resemble table functions should return a schema type and pipelined table functions, perhaps because that they don't in fact return a collection, rather they return (RowSource) content, can use the schema types or types of packages. Is this correct?

  Can someone clarify this for me please?

  Thank you in advance,

• Return type of dataframe string identifier

  Hello
  
  If I have to return a dataframe of rqScript which contains the string, how am I suppose to mention it in the return type of rqTableEval.
  
  For example, if the return value of rqScript is

  data.frame (c (1), c("Name"))

  , which is a number and the other string
  Then in the rqTableEval, identify the return values
  

  'select ID, 1 '1' chain of double'

  1 works as an identifier for the numbers but '1' doesn't work, '1' as an invalid identifier for the return string
  
  I tried with the host of permutations "-* ','. '. "\ *", "a" etc., none seems not to work
  
  Can I please get help on which must be specified as an identifier for the string type?
  
  Published by: Kedar Gupte on May 21, 2013 01:52

  Kedar,

  The string must be long enough to accommodate the output. For example, for a maximum length of 10 characters, you can do "Lucy" or cast ('a' as varchar2 (10)). You must also use single quotes instead of double quotes. In SQL double quotes are used to specify the identifiers (such as table names, column names, etc.). In your example, '1' is an unknown identifier. What you need is a string literal.

  As you said already FETCH retrieves the next line, if any. A query is a request is a request. It returns a result set. A query that uses aggregates returns a result set. A query that does not aggregate returns a result set.

  Your simple COUNT (*) SELECT query returns a result set that consists of a LINE and a line a ONE COLUMN of type NUMBER. Although there is only one column in the result set, what is returned is a RECORD or a LINE. That's why you have to report your data cursor return type a document using the % ROWTYPE or % TYPE attributes or a record structure.
