How to access the variable script proc SQLplus?

Lets start with the following SQLplus script:

variable username varchar2 (100);
Start select user in: user name of double; end;
/

print the user name;

Select * from WHERE = owner all_tables "& username'"




Issues related to the:

Why do I get invited to enter a "/" when running the script in SQLplus? Even if I insert a / after the username 'impression' statement I am invited to enter an end delimiter.

In addition, I would like to access the user name value in the following SELECT statement. However when I as code above the value of the variable is not taken. Instead, the user is prompted to enter a user name.

No there is no way to 'transfer' of the value of the SQL user name?

Peter

You're confusing SQL * more variable substitution (those with '&') and bind variables.

Replace the "& username" with: username as shown below:

SQL> variable username varchar2(100);
SQL> begin select user into :username from dual; end;
  2  /

PL/SQL procedure successfully completed.

SQL> print username;

USERNAME
---------------------------------------------------------------------------
SCOTT

SQL> select * from all_tables WHERE owner=:username;

  • How to access the variable in the child video clip

    I have a flash file that uses php to manipulate a database and returns a variable (data_xml) to document data in XML from the database. In this case, as well as others within the parent company. Now, I have a child movieclip that shows analyzed data, but I'm unable to access the variable from the child movieclip. The code associated with this is:

    var myXML:XML = new XML();
    var myXML = XML (event.currentTarget.root.data_xml);

    and I get the following two errors that point to the second line as the problem:

    1151: there is a conflict with definition myXML in the internal namespace.

    WARNING: 3596: duplicate variable definition.

    I unchecked automatically "declare instances of the scene" because I have seen the one proposed for the 1151: error, but I still have not the same two errors.

    Can anyone help? Thank you!

    You've declared the variable twice. Variable can be declared only once in any scope. So, your code should be:

    var myXML:XML = new XML();
    myXML = XML (event.currentTarget.root.data_xml); Note there is no before var

  • How to access the variable JoinColumn directly in an entity.

    E1.employee_id = 1;
    E1.Employee_Name = "Employee1";
    E1. Department = d;

    Is there a way to uncomment Employee.emp_department_id and insert data about employees using PT. 1 ???

    The correct method is to define the ManyToOne and set it to the appropriate Department. You can use find() or getReference() to get the service object with the ID.

    If you want to have a base for both Id mapping, then you must use the same column name.

    @JoinColumn (name = "emp_department_id")

    should be,

    @JoinColumn (name = "EMP_DEPARTMENT_ID")

    But since you have two mappings for the same column, you must set one of them write,

    @JoinColumn (name = "EMP_DEPARTMENT_ID", insertable = false, updatable = false)

    Or you could remove the ManyToOne and have just the base.

  • How we use the variable checkbox?

    I use Cap 8. Finally, I want to set a variable to store the user's decision to play any narration automatically, or do not play automatically narration.

    A check box appears as a perfect way to let the user make this decision, so I used the box widget to display only a single checkbox. Successfully, I set the text property of checkbox and entered a unique variable name (myNarrationDefault) to store the State of the checkbox. Now how to access the variable?

    I added a text field, so I could see the value of this variable. However, when I try to insert a variable, I don't see the new user variable, in the list. Then I tried to add an action to a button just to see if the variable appears in the tool; There can be no.

    I'm doing something wrong?

    Thank you

    Pete

    In fact, you will need to create so that the variable you made in the interaction interface, CP does not do it for you, project/Variables in the top Menu.

    When the box is checked, the value is then assigned to the variable.

  • How to remove the variable created when using definedNamedWhereClauseParam()

    Hello

    My Jdev version 11.1.1.7.0.

    I'm Executive where clause programatically where I need to bind two bind parameters under certain conditions. Example, I have two bind variables X, Y.

    Here's the problem:

    Assume that the first time I'm setting one variable X, so I define X bind variable and execute the query.

    What second time I send only Y but not X. In this implementation of the scenario of VO throw an exception, given that the variable X is already created in the VO object and where clause does not have this setting.

    So how to remove variables created in the original Version all in definedNamedWhereClauseParam(). I need to erase what ever the previously created variable every time I execute method.

    I can make the similar functionlity using setWhereClauseParam (using literals). But I have a few technical restrictions for use.

    Could you please help me how to remove the variable before vo using definedNamedWhereClauseParam.

  • How to access the BPM 11 g load useful or process varibles in the workflow of ADF

    I'm trying to view/edit the data in a user interface that is linked to a database by using a foreign key, requestId. The foreign key comes from a BPM process where it is spent in the workflow, a human task. The foreign key comes process variables or values of payload. I know that I can simply load the payload in BPM with the data in the tables, but I'm looking for a better solution use the ADF business components to view and edit data directly in the user interface.

    The BPM process uses a web service to start the process. Web services takes a primary key as a parameter to reference a column in the database table. The data is pre-filled with content and a primary key reference. The first activity is an activity of the user. I want the workflow behind the user activity to accept this primary key and use to locate the line in the database, so related views of the database delimited ADF business components can work to present the data in the user interface.

    I tried two approaches to the problem. The first uses the setCurrentRowWithKeyValue operation. The other changes the SQL where clause, used by the ADFbc iterator only returns one row for the given requestId. Both of these approaches fail to work because I don't know how to access the load BPM or variable data entering the workflow. Here is the piece of code that I used to try to define the row using the value of setCurrentRowWithKey:

    public String setRequestId() {}

    FacesContext context = FacesContext.getCurrentInstance ();
    Object requestObj = context.getApplication () .evaluateExpressionGet)
    context, "#{bindings."(, Number.class) RequestId.inputValue "};
    If (requestObj is nothing)
    Returns a null value.
    RequestId number;
    requestId = (number) requestObj;

    ITR DCIteratorBinding = (DCIteratorBinding)

    getBindings () .get ("PatfRequestHdrView1");

    itr.setCurrentRowWithKeyValue (requestId.toString ());

    Returns a null value.

    I didn't get very far with the second approach, change SQL where clause, because I do not know Groovy. I think I need something like:

    adf.object.viewObj.RequestId. but it is not a viewObject associated with BPM data, so I don't know that this particular expression will not work.

    Any help you can give me is greatly appreciated.

    Kind regards
    Mark

    Try this code in your method:

    FacesContext context = FacesContext.getCurrentInstance ();
    String ctx = (String) context.getApplication () .evaluateExpressionGet (context, "#{pageFlowScope.bpmWorklistContext}", String.class);
    String tskId = (String) context.getApplication () .evaluateExpressionGet (context, "#{pageFlowScope.bpmWorklistTaskId}", String.class);
    IWorkflowServiceClient workflowSvcClient = WorkflowService.getWorkflowServiceClient ();
    ITaskQueryService wfQueryService = workflowSvcClient.getTaskQueryService ();
    IWorkflowContext wfContext = wfQueryService.getWorkflowContext (ctx);
    Task myTask = wfQueryService.getTaskDetailsById (wfContext, tskId);
    XMLElement xmlPayload = (XMLElement) myTask.getPayloadAsElement ();
    get the payload as a string simple, useful for debugging
    java.io.StringWriter writer = new java.io.StringWriter ();
    xmlPayload.print (writer);
    String payloadAsString = writer.toString ();
    extract payload values: use methods in Oracle XDK
