Dynamic Tag Query with dynamic tag name.

Hi,
In our implementation we have 10+ users. Each one want to monitor only one production line ( eg. one tag value ) in the dashboard by default when they login.
I was able to design this requirement CONCEPTUALLY but facing some trouble technically.
Here is my issue.
Tagname will be coming from one of the BLS Transaction input parameters (Transaction.Tagname). I am able to build tag query using xMII Tag Query block, able to configure repeater. Here is the spot where I was struck. While assigning tag value to XML Row
i.e IlluminatorRow_0.Tagvalue = Repeater_0.Output{/Row/AssetUtil1}.
In the above assignment link it requires a hardcoded tagname. In my case it will be dynamic. I tried different ways like
1. IlluminatorRow_0.Tagvalue = Repeater_0.Output{/Row/@Transaction.Tagname}.
2.IlluminatorRow_0.Tagvalue = Repeater_0.Output{/@Transaction.Tagname}.
But no luck.
Can someone help in how to do this dynamic tagname assignment.
Thanks,
Srinivasa.

Hi Srinivas,
another option is to use "Dynamic Links" which from your sample code is what you were trying to do. For this, the proper syntax is:
Repeater_0.Output{/Row/#Transaction.Tagname#}
Make sure that the tag name you pass to the historian is the same as the tag name returned by the historian as part of the data set, and make adjustments for that. For example, some historians escape non-alphanumeric characters when they process your request (e.g. passing "abc.def 12-rt" as the tag name can be returned from the historian as "ABC.DEF_12_RT", etc.).
Hope this helps,
Sascha

The above given logic of mine works for you, put the code in the If condition and try-
just like below:
IF NOT P_EBELN IS INITIAL.
lt_where = '& = ''&'' '.
REPLACE '&' WITH p_ebeln INTO lt_where.
REPLACE '&' WITH field_value INTO lt_where.
SELECT (lt_sel_list) INTO CORRESPONDING FIELDS OF TABLE <lt_outtab>
FROM (p_tabnam)
WHERE (lt_where).
ENDIF.

Absolute dynamic select query with dynamic join and where

Has anyone ever tried creating an absolutely dynamic SELECT query with dynamic Join and Where conditions.
I have a requirement of creating such a query in an Utility Class, and i have written the code. But its throwing my sysntax errors.
Please let me know where am I going wrong OR is it really possible to create such a dynamic Query??
 SELECT (FIELDS) INTO TABLE IT_TABLES
 FROM ( (ME->TABLE1) inner join ( me->table2 )
 on ( on_condition ) )
 WHERE (me->where_fields).
Ags.

It worked for me in a following way:
select * into corresponding fields of table <result_table>
 from (join_string)
 where (l_where).
Where the contents of join_string were dynamically build using concatenation. So it will be something like
concatenate ME->TABLE1 'as a INNER JOIN' me->table2 'as b ON (' into join_string separated by space.
<...>
add here matching/reference colums, something like
concatenate 'a~' me->TABLE1_JOIN_COL into temp1.
concatenate 'b~' me->TABLE2_JOIN_COL into temp2.
concatenate join_string temp1 '=' temp2 into join_string separated by space.
<...>
concatenate join_string ')' into join_string separated by space.
And then use similar approach for l_where variable.

Running a SQL Stored Procedure from Power Query with Dynamic Parameters

Hi,
I want to execute a stored procedure from Power Query with dynamic parameters.
In normal process, query will look like below in Power Query. Here the value 'Dileep' is passed as a parameter value to SP.
    Source = Sql.Database("ABC-PC", "SAMPLEDB", [Query="EXEC DBO.spGetData 'Dileep'"]
Now I want to pass the value dynamically taking from excel sheet. I can get the required excel cell value in a variable but unable to pass it to query.
    Name_Parameter = Excel.CurrentWorkbook(){[Name="Table3"]}[Content],
    Name_Value = Name_Parameter{0}[Value],
I have tried like below but it is not working.
Source = Sql.Database("ABC-PC", "SAMPLEDB", [Query="EXEC DBO.spGetData Name_Value"]
Can anyone please help me with this issue.

Creating Query with dynamic columns to show results

Hi experts,
I need to know how to create a query with dynamic columns. Meaning, I don't want to create a query with fixed columns representing the 12 periods of the fiscal year to show me actuals as the fiscal year proceeds.
For example, if I am currently in the middle of period 3 (March) of a fiscal year, when I execute the query, I need it to automatically only show me the 'Actuals' for periods 1 and 2, without seeing the columns from periods 3 to 12 showing blank.
Then when I am in the middle period 5 (May) the query should ONLY show me the columns for periods 1 to 4 'Actuals', no results should be shown for periods 5 to 12 yet, and I don't want to even see blank columns for period 6 to 12.
How do I define my columns, to achieve this.
Maximum points will be awarded.
Thanks Everyone.

Hi Josh,
I'm having a little difficuluty understanding what should be included in my restricted key figures.
The time characteristics that I have available to use are:
0FISCPER3 (posting period)
0FISCYEAR (fiscal year), currently using SAP EXIT to default current fiscal year.
0FISCVARNT (fiscal year variant).
In addition, I have the following characteristics available to be used in the columns:
Value type (10)
version (currently I'm using variable for it)
Currency type (020)
Currency (USD).
Can you explain what my restricted key figure should be based on and how it should look.
I tried to create a restircted key figure using 0AMOUNT, and 0FISCPER3. For 0FISCPER3 I created a range from 1 to previous period (using SAP EXIT that supplied previous period).I also had value type, version, currency type, and currency included in that restricted key figure.Then when I tried to drag 0FISCPER3 under the restricted key figure once again, it wouldn't let me, probably because I've already used 0FISCPER3 in the restricted key figure.
Please let me know if my explanation is not clear.
Your step by step help would be great.
Thanks

Global query block is causing a DNS server to fail a query with error code Name Error exists in the DNS database for WPAD

Global query block is causing a DNS server to fail a query with error code Name Error exists in the DNS database for WPAD on a Windows 2008 server.

The global query block list is a feature that prevents attacks on your network by blocking DNS queries for specific host names. This feature has caused the DNS server to fail a query with error code NAME ERROR for wpad.contoso.com. even though data
for this DNS name exisits in the DNS database. Other queries in all locally authoritative zones for other names that begin with labels in the block list will also fail, but no event will be logged when further queries are blocked until the DNS server
service on this computer is restarted.

Tag Query with Special Characters in Tag Name not working

Hello-
We are on SAP xMII 12.0 sp8.6, connecting to Honeywell's PHD. We are doing Tag Queries, and all is working well, except when there are special characters in the Tag Name (+, /, \) We have attempted to do the Encoding of the tag name, such as as is returned from the function xmlencodename and also tried URL Encoding.
Here is our tag which returns nothing.
82TK1INV.OCTANE_R+M/2
We have also tried these encoded versions, still to no avail:
82TK1INV.OCTANE_R%2BM%2F2
82TK1INV.OCTANER_M_2
Any help on how to return the values with special characters in the tag name would be very helpful!
thanks,
Paul Mazeika

To Chianti's question of why can't/shouldn't MII work with those bizarre tag names...
Actually, there are a number of reasons:
1) It's a poor design practice to use characters like that in tag names, regardless of the underlying system. That type of information is best assigned to the tag description, not the tag name. I've even seen idiots put leading spaces on tag names...figure that one out!
2) MII uses XML extensively, and XML's syntax rules dictate what is and is not acceptable for XML element and attribute names, and many of these special characters are not permitted.
3) Usage of characters in tags that also represent mathematical operators greatly complicate the parsing and processing of expressions that involve tag names
In general, it reminds of the story of the guy who walks into the doctor, bangs his fist against a specific spot on his head, and says "Doc, it hurts when I do this", to which the doctor responds, "so don't do that".
So, Don't Do That.

Hi,
Sorry, I don't see what you're trying to do.
"Dynamic SQL" is really a mis-nomer. The number of tables and columns in a query, and their names, must be spelled out when the statement is compiled. There is nothing dynamic about it.
In dynamic SQL, a PL/SQL procedure or another query writes all or part of query just milliseconds before it is compiled, typically using data taken from tables or supplied by a user right then.
For example, consider this static query:
SELECT a.col1, a.col2, b.col1, b.col7
FROM table_1 a
, table_2 b
WHERE a.col1 = b.col1;Now, say the 1 in "table_1" and the 2 in "table_2" are variables, x and y, that you will want to look up from another table every time you run this query. You can make it dynamic like this:
sql_txt := 'SELECT a.col1, a.col2, b.col1, b.col7 '
 || 'FROM table_' || TO_CHAR (x) || ' a '
 || ', table_' || TO_CHAR (y) || ' b '
 || 'WHERE a.col_1 = b.col1';Now let's make it really interesting. Say that instead of 2 tables, and 1 join condition, you''ll have n tables and n-1 join conditions, where n has to be computed at (actually a split second before) run-time. That is, if n=4, you might need to construct a static query with 4 tables and 3 join conditions, like this:
SELECT a.col1, a.col2, b.col1, b.col7
FROM table_1 a
, table_2 b
, table_12 c
, table_2 d
WHERE a.col1 = b.col1
AND a.col1 = c.col1
AND a.col1 = d.col1;You can do that using dynamic SQL, too.
Post an example of the static query you need to build, and describe what parts of it are dynamic, and how you get the values for those parts, and someone will help you write the dynamic SQL.

Sql query with dynamic fiscal year

Hi,
I wrote this query with static fiscal year and fiscal period, I need info on making the variables dynamic
Fiscal year : starts from July1st. So this year until June'30 it is '2011' and from July'1st its '2012'
Fiscal period: July1st its '1' and June'1st its '12'
Query:
select distinct o.c_num, o.ac_num, s.sub_ac_num, o.fiscal_year, o.ac_exp_date, s.sub_ac_ind
                         from org_account o
                              left outer join sub_account s
                              on o.c_num = s.c_num and o.ac_num = s.ac_num
                         where (o.ac_exp_date >= CURRENT_DATE or o.ac_exp_date is null)
                         and o.fiscal_year = *'2011'* --> need to be dynamic
                         and o.fiscal_period = *'12'* --> need to be dynamic

Hi, Mano,
Welcome to the forum!
Whenever you have a question, please post a little sample data (CREATE TABLE and INSERT statements), and the results you want from that data.
Always say which version of Oracle you're using.
Since this is your first thread, I'll post some sample data for you:
CREATE TABLE     table_x
(     dt     DATE
INSERT INTO table_x (dt) VALUES (DATE '2010-12-31');
INSERT INTO table_x (dt) VALUES (DATE '2011-01-01');
INSERT INTO table_x (dt) VALUES (DATE '2011-06-02');
INSERT INTO table_x (dt) VALUES (DATE '2011-06-30');
INSERT INTO table_x (dt) VALUES (DATE '2011-07-01');Is this the output you would want from that data?
DT          FISCAL_YEAR     FISCAL_PERIOD
31-Dec-2010 2011            06
01-Jan-2011 2011            07
02-Jun-2011 2011            12
30-Jun-2011 2011            12
01-Jul-2011 2012            01If so, here's one way to get it:
SELECT       dt
,       TO_CHAR ( ADD_MONTHS (dt, 6)
            , 'YYYY'
            )     AS fiscal_year
,       TO_CHAR ( ADD_MONTHS (dt, 6)
            , 'MM'
            )     AS fiscal_period
FROM       table_x
ORDER BY dt
;Since your fiscal year starts 6 months before the calendar year, you need to add 6 months to the actual date to get the fiscal year and month.
The query above produces strings for fiscal_year and fiscal_period. If you'd rather have NUMBERs, then use EXTRACT instead of TO_CHAR:
SELECT       dt
,       EXTRACT (      YEAR
            FROM     ADD_MONTHS (dt, 6)
            )     AS fiscal_year
,       EXTRACT (      MONTH
            FROM     ADD_MONTHS (dt, 6)
            )     AS fiscal_period
FROM       table_x
ORDER BY dt
;The first query will work in Oracle 6 (and higher).
I'm not sure when EXTRACT was introduced. It definitely works in Oracle 10, and may be available in earlier versions, too.

Input query with dynamic actual & forecast values by month per year

Hello,
I am working on a Input ready query for a forecasting application which shows both actuals and forecast numbers and the user will revise the forecast numbers by month
Requirement: I want to build a Input query for monthly forecasting for the current year. It will be dynamic rolling of months with actuals & forecast data.
E.g. My report has 12 months for the current year
and if run the report in May, the months before May has to show the actuals and the months after May has to show the old forecast data so that the user will revise the numbers again in each month and save the data to the real time cube.
Jan.Feb.Mar.Apr.May.Jun.Jul.Aug.Sept.Nov.Dec
Act Act Act Act Act Old frcst for the remaining months
user will revise forecast for these months
So, i am able to create Input query with all restricted key figures( plan kf has change mode set to change, actual kf are not set change) and calculate key figures and all the logic is done on dynamically moving/rolling the data based on the input month of the year.
But the problem is that i am using cal kf to dynamically roll months, i was not able to set the change option for the cal kf.
So, how can i make sure that the dynamically changed plan months will open for entering forecast and the actuals months not to change?
Do you guys have any better solutions in implementing it?
I really appreciate it your input....:)
Thanks,
Srini

Input-Ready Query
Use
You use input-ready queries to create applications for manual planning. These can range from simple data entry scenarios to complex planning applications.
Integration
You define a query that you want to use for manual planning in the BEx Query Designer (see Defining New Queries).
In the Web Application Designer or the BEx Analyzer, you can combine the input-ready queries with other queries and planning functions to create complex planning applications.
Prerequisites
You can define an input-ready query on any of the following InfoProviders:
●     Aggregation levels (see Aggregation Levels)
●     MultiProviders that include at least one simple aggregation level
The aggregation levels are created in the planning modeler; MultiProviders are defined in the modeling functional area of the Data Warehousing Workbench.
Features
Definition of an Input-Ready Query
Once you have defined a query on an InfoProvider, you see the Planning tab page under the Properties of structural components (for example, in key figures or restricted key figures). The options provided there allow you to determine which structural components of an input-ready query are to be input ready at runtime and which are not. With structural components that are not input ready, you can also determine whether these components are viewed as reference data or are just protected against manual entry.
For the structural components, you also have the following options:
Input readiness of structural components of a query
Option
Description
Not input ready (reference data)
If they are being used as reference data, the structural components are not protected by data locks to ensure exclusive access for one user because this data serves as a reference for many users.
This is the default setting.
Not input ready (no reference data)
If you want to protect structural components against manual entries but allow changes by planning functions, you can use locks to protect this data for one particular user. In this way you can ensure that the planning function works with the displayed data only and not with data that has been changed by other users.
Input ready
You can also determine whether an input ready query is to be started in change mode or in display mode. You find this property in the Query Properties on the Planning tab page. If there is at least one input-ready query component, the query (as long as it has not been determined otherwise) is started in display mode.
In BI applications that use input ready queries as data providers, you can enter data manually at runtime. For more information, see Performing Manual Planning and Creation of Planning Applications.
Example
You want to create an input-ready query for manual planning for a plan-actual comparison of revenues for a set of products. You want the plan data in a real-time-enabled InfoCube and the actual data in a standard InfoCube.
       1.      Create a MultiProvider that includes the InfoCubes for the plan and actual data.
       2.      Define an aggregation level on the MultiProvider which contains the characteristic Product and the key figure Revenue.
       3.      On the aggregation level, create two restricted key figures Plan Revenue and Actual Revenue. For restriction, choose the characteristic 0INFOPROV and restrict it to the plan or actual InfoCube.
       4.      Add the restricted key figures to the key figure structure. Insert Product into the rows. For Plan Revenue, choose Input Ready for the input-readiness option. For Actual Revenue, choose the option Not Input Ready (Reference Data).
       5.      In the query properties, set the indicator that determines whether the queries are started in display or change mode as required.
Example of an input-ready query
Product
Plan Revenue
Actual Revenue
P01
20
P02
30
If you want to keep actual and plan data in a real-time enabled InfoCube, you do not require a MultiProvider for the task described above. Create an aggregation level on the InfoCube and define the input-ready query for the aggregation level. In the example above, a version characteristic acts as the InfoProvider. Create restricted key figures with the plan or actual version and proceed as in the previous example.

Query with dynamic variables and customised caption

How to change the Field label when the query asking dynamic values during the execution?
for example: in where condition i want to give a country name during the query execution, but in the small window it will display as 'Name' which is a country name. i want to display it as 'Country Name' which should be more readable for the end user. How can we achieve this?
Thanks

Dynamic REF Cursor with Dynamic Fetch - Urgent

i have a pl/sql package with generates dynamic SQL statments. my problem is i want to open this SQL statment dynamically and fetch data in dynamic variable.
declare
type type_temp is REF CURSOR;
cur_temp type_temp;
mv_sql varchar2(4000);
begin
-- this will be dunamically generated and
-- hence could have any no. of columns.
mv_sql := select f1, f2, f3, f4 from table_temp;
open cur_temp for mv_sql;
fetch cur_temp into c1, c2, c3, c4;
close cur_temp;
end;
problem is my sql statment will have N no. of columns how can i fetch this N no. of columns.

Very hard problem, because ref cursors do not (directly) support description!

END LOOP;
l_record_def := RTRIM (l_record_def, ',');
RETURN l_record_def;

END;
Note that procedure "record_def" creates columns names as col_1 (col_2 ...)
because SELECT clause in your query can be without aliases, for example
"SELECT deptno || dname FROM dept".
2. Your package which returns query nad ref cursor
CREATE OR REPLACE PACKAGE test IS

Why we need two separate procedures (functions) in your package ?
a) Receiving program must use dynamic SQL, but in dynamic block we can access
only PL/SQL code elements that have global scope (standalone functions and procedures,
and elements defined in the specification of a package).
Unfortunately, cursor variables cannot be defined in the specification of a package
(cannot be global variables).
b) Receiving program must get the column list before ref cursor.
So, we have two options: call (in receiving program) the same function two times
(once to get the column list and once to return a ref cursor)
or use one procedure (or function) for returning query (to get the column list)
and second function for returning a ref cursor.
3. Your receiving program
CREATE OR REPLACE PROCEDURE test_fetch_ref_cur (p_query VARCHAR2 := NULL) IS
l_statement VARCHAR2 (32000);
FUNCTION process_def RETURN VARCHAR2 IS
l_process_def VARCHAR2 (32000);
BEGIN
l_process_def := 'DBMS_OUTPUT.PUT_LINE (';
FOR i IN 1 .. dyn_fetch.g_count LOOP
l_process_def := l_process_def || ' l_record.col_' || i || ' || ''>>'' || ';
END LOOP;
l_process_def := RTRIM (l_process_def, ' || ''>>'' || ') || ');';
RETURN l_process_def;
END;
BEGIN
test.set_query (p_query);
dyn_fetch.describe_columns;
l_statement :=
' DECLARE' ||
' TYPE record_t IS RECORD (' ||
dyn_fetch.record_def || ');' ||
' l_record record_t;' ||
' l_ref_cur dyn_fetch.ref_cur_t;' ||
' BEGIN' ||
' l_ref_cur := test.ref_cur;' ||
' LOOP' ||
' FETCH l_ref_cur INTO l_record;' ||
' EXIT WHEN l_ref_cur%NOTFOUND;' ||
process_def ||
' END LOOP;' ||
' CLOSE l_ref_cur;' ||
' END;';
EXECUTE IMMEDIATE l_statement;
END;
You can test this with:
SET SERVEROUTPUT ON;
EXECUTE test_fetch_ref_cur;
Note that we can try to use more generic solution:
CREATE OR REPLACE PACKAGE dyn_fetch IS
-- SAME AS BEFORE, PLUS:
PROCEDURE fetch_ref_cur (
p_function_ref_cur VARCHAR2,
p_process_def VARCHAR2);
END;
CREATE OR REPLACE PACKAGE BODY dyn_fetch IS
-- SAME AS BEFORE, PLUS:
PROCEDURE fetch_ref_cur (
p_function_ref_cur VARCHAR2,
p_process_def VARCHAR2)
IS
l_statement VARCHAR2 (32000);
BEGIN
l_statement :=
' DECLARE' ||
' TYPE record_t IS RECORD (' ||
record_def || ');' ||
' l_record record_t;' ||
' l_ref_cur dyn_fetch.ref_cur_t;' ||
' BEGIN' ||
' l_ref_cur := ' ||
p_function_ref_cur || ';' ||
' LOOP' ||
' FETCH l_ref_cur INTO l_record;' ||
' EXIT WHEN l_ref_cur%NOTFOUND;' ||
p_process_def ||
' END LOOP;' ||
' CLOSE l_ref_cur;' ||
' END;';
EXECUTE IMMEDIATE l_statement;
END;
END;
CREATE OR REPLACE PROCEDURE test_fetch_ref_cur (p_query VARCHAR2 := NULL) IS
FUNCTION process_def RETURN VARCHAR2 IS
-- SAME AS BEFORE
END;
BEGIN
test.set_query (p_query);
dyn_fetch.describe_columns;
dyn_fetch.fetch_ref_cur (
p_function_ref_cur => 'test.ref_cur',
p_process_def => process_def);
END;

How to create a dynamic table region with dynamic VO

Hi All,
I have a requirement to create a dynamic table region with a dynamic VO.
I need this because at runtime only the user will select the table name. So based on that table name, i have to create a table region to display the records.
I already created a dynamic VO. Could anyone share the code for dynamic table region creation.
Thanks in Advance.
Thanks and Regards,

Hi,
You can use following sample code to create advance table columns dynamically with colum groups as well.
It assumes that you have already created advance table with ID EmpTblRN.
Below code returns column heading dynamically and if you keep your VO column names and attributes
same in all the cases (COL1, COL2.....) then you can easily use a loop to create advance table columns.
It is attaching VO attributes to OAMessageStyledText bean in the last.
Hope it helps.
OAAdvancedTableBean advTable = (OAAdvancedTableBean)webBean.findChildRecursive("EmpTblRN");
Serializable [] param = {currentWindowSeq.toString()};
Datum[] colHeadingArray = (Datum[])am.invokeMethod("getColumnHeading", param);
String oldGrpName = null;
String newGrpName = null;
OAColumnGroupBean columnGroup = null;
DictionaryData columnFormat = new DictionaryData();
columnFormat.put(WIDTH_KEY, "4%");
for (int i = 0; i < colHeadingArray.length; i++)
try
oracle.sql.STRUCT os = (oracle.sql.STRUCT)colHeadingArray;
Object[] colHeadAttr = os.getAttributes();
newGrpName = (String)colHeadAttr[0];
if(newGrpName!=null)
if(!newGrpName.equals(oldGrpName))
// Create a column group, create the set the column header,
// and add the column group under the advanced table
columnGroup = (OAColumnGroupBean)createWebBean(pageContext, COLUMN_GROUP_BEAN, null, "ColGroup"+i);
OASortableHeaderBean columnGroupHeader = (OASortableHeaderBean)createWebBean(pageContext, SORTABLE_HEADER_BEAN, null, "ColGroupHeader"+i);
columnGroupHeader.setText(newGrpName);
// Retrieve from message dictionary
columnGroup.setColumnHeader(columnGroupHeader);
advTable.addIndexedChild(columnGroup);
oldGrpName = newGrpName;
// Create a column, create the set the column header, and add the column
// under the column group
OAColumnBean column1 = (OAColumnBean)createWebBean(pageContext, COLUMN_BEAN, null, "Column"+i);
OASortableHeaderBean column1Header = (OASortableHeaderBean)createWebBean(pageContext, SORTABLE_HEADER_BEAN, null, "Column1Header"+i);
column1Header.setText(colHeadAttr[1].toString());
column1.setColumnHeader(column1Header);
column1.setColumnFormat(columnFormat);
columnGroup.addIndexedChild(column1);
// Create the actual leaf item under the first column
OAMessageStyledTextBean leaf1 = (OAMessageStyledTextBean)createWebBean(pageContext, MESSAGE_STYLED_TEXT_BEAN, null, "Leaf"+i);
//OARawTextBean leaf1 = (OARawTextBean)createWebBean(pageContext, RAW_TEXT_BEAN, null, "Leaf"+i);
leaf1.setViewAttributeName("Week"+(i+1));
String destination = "OA.jsp?page=/xxqc/oracle/apps/per/leaveadvance/webui/EmployeeLeaveDetailPG&personId={@PersonId}";
destination = destination + "&startDate="+colHeadAttr[1].toString()+"-"+(String)colHeadAttr[0];
destination = destination + "&addBreadCrumb=Y&retainAM=Y";
leaf1.setDestination(destination);
OADataBoundValueViewObject cssjob = new OADataBoundValueViewObject(leaf1,"Color"+(i+1));
//leaf1.setAttributeValue(oracle.cabo.ui.UIConstants.STYLE_CLASS_ATTR, cssjob);
leaf1.setAttributeValue(UIConstants.RENDERED_ATTR, cssjob);
column1.addIndexedChild(leaf1);
catch(Exception e)
System.out.println("e"+e);
