How to use an if statement in javascript code

Hello,
I have a batch processing script to search for text "employee signature" on each page in a multiple page file and to then list in the console any pages that do not have the "Employee Signature" text included.
The script is not yet functional as an if statement needs to be included.
Can anyone please advise how to use an if statement in javascript code?
var numpages = this.numPages;
for (var i=0; i < numpages; i++)
search.query("Employee Signature", "ActiveDoc");
console.println('Pages that do not include an employee signature: ' + this.pageNum +' ');
Any assistance will be most appreciated.

Thank you very much for your assistance try.
I have modified the code as suggested and the page numbers are now listing correctly, thank you, but....................,
The console lists every page as having an "employee signature" when there are pages in the document that do not have an employee signature.
The code (revised as follows) is not processing the "getPageNthWord part of the statement" in the console report?
Can you please advise where the code needs reworking?
var ckWords; // word pair to test
var bFound = false; // logical status of found words
// loop through pages
for (var i = 0; i < this.numPages; i++ ) {
 bFound = false; // set found flag to false
 numWords = this.getPageNumWords(i); // number of words on page
 // loop through the words on page
 for (var j = 0; j < numWords; j++) {
 // get word pair to test
 ckWords = this.getPageNthWord(i, j) + ' ' + this.getPageNthWord(i, j + 1); // test words
 // check to see if word pair is 'Employee' string is present
 if ( ckWord == "Employee") {
 bFound = true; // indicate found logical value
 console.println('Pages that includes an employee signature: ' + (i + 1) +' ');
 break; // no need to further test for this page
 } // end Employee Signature
 } // end word loop
 // test to see if words not found
 if(bFound == false) {
 console.println('Pages that do include an employee signature: ' + (i + 1) +' ');
 } // end not found on page
} // end page loop
Thank you

you cannot place your if conditions within form fields in the Word header. But you can directly type the tags instead.

How to use multiple WSDL operations in One BPEL process Recieve Activity ?

Is there anyway to attach multiple WSDL operations with a Single BPEL process ? How ?

Thanks Melvin for your quick respond.
When I create a BPEL process, It asks me to give the XSD as an Input. When I import the XSD it asks me to select an operation not more than one. Let suppose I select addRequest and finish the wizard.
Now what I can see, It create Recieve activity with an Input msg of Add operation. Well what I understand from your statement is that, I remove the recieve activity and put the Pick activity.
Now my question is How to mention the other operations like update and delete ? And how to test them ?? The link provided by you is just tell me what Pick activity can do for me, But its not telling me how to use it ?? and how the give the operation to it. Where should I need to change in the BPEL ???

How to use Native SQL statement in JDBC receiver interface

Dear All,
Can any one please help us in using Native SQL statement in a JDBC receiver channel. The reason why I need to use Native SQL statement instead of standard XML structure is that I need to execute a dynamic SQL query in third party database system lke:-
Select Field1 Field2 from TABLE Where Field3 like "%Name'
I expect the the response in the form of XML file which I can pick up using synchornous interface as mentioned on help.sap.com:-
http://help.sap.com/saphelp_nw04/helpdata/en/64/ce4e886334ec4ea7c2712e11cc567c/frameset.htm
http://help.sap.com/saphelp_nw04/helpdata/en/64/ce4e886334ec4ea7c2712e11cc567c/frameset.htm
The value for %Name can change dynamically according to the transaction and hence cannot be inluded as a KEY element in standard XLM structure,
Hence I need to know:-
1. What message mapping I should use in case if I have to use Native SQL statement.
2.What operation mapping I should use in case if I have to use Native SQL statement.
If guess correclty I may have to use Java mapping to do the above activities. Hence I want to know
3 .How do to go about it to do the Java mapping.
Thanks

You can use a stored procedure, and call it from jdbc receiver adapter.
I also solve this issue, with a DBLookup in message mapping. You can refer to my blog, and this usefull 3d:

How to use a select statement with chinese characters?

I am currently developing a java servlet<using tomcat 4.x> which allows me to use select statement to retrieve results from the Microsoft SQL Server 2000 database. I am using a simple form to get the parameter for querying. The main problem i'm facing is that there are chinese information in the SQL database, but i can't retrieve it through the sql statement with the chinese characters input<thru the form with the help of NJ STAR>in the WHERE condition. When i execute the statement, it returns me no results even though the rows are present in the database.
Does anyone have the solution to using chinese words in the WHERE clause of the select statement to retrieve results with columns which contains chinese characters? Please help me. Thanks everyone. :)
PS: when i cut and paste those characters in the sql database and paste onto java.. it is ??? in questionmarks.. but when i paste them into excel 2000.. its shown as chinese chars again..
please heelppp~~

Greetings,
PS: when i cut and paste those characters in thesql
database and paste onto java.. it is ??? in
questionmarks.. but when i paste them into excelThis is why the SELECT is not returning any results.
You need to set the character encoding set on your
statement and parameters for the characters to be
properly translated. Refer to the charsetName
parameter in the String class constructor in your API
docs and also to
$JDK_DOCS/guide/intl/encoding.doc.html in your JDK
documentation.
2000.. its shown as chinese chars again..Because Office programs are performing the same kind
of character translation with the appropriate MS APIs.
please heelppp~~Regards,
Tony "Vee Schade" Cookis it possible for you to show me some coding examples? i don't really understand what is to be done in order to set the char set and what does it really do.. tried reading up but still dun understand.. :(
pardon my shallow knowledge of java..
ok..
The thing is when i used an insert statement with chinese characters of GBK format hardcoded into the java servlet and then i use the insert statement to insert the chars into the database, it cannot be seen as a chinese word when i off the NJStar. and then it can be searched out with my current form of servlet.. below is my coding of the servlet..

How to use a case statement in where clause

Hi All,
I have a requirement which is to bring all the claims that are created in the last month.So, i wrote a query something like this
select * from claims
where
(Month(ClaimOpenDate) = Month(Getdate())-1 and year(claimopendate) = year(getDate()))
which would give me any new claims created in last month of current year, but this condition fails if we are in the first month of a new year( lets say if we are in 2016 jan then month(getdate())-1 would be 0 and year(getdate()) would be 2016 so we dont
find any records where year is 2016 and month is 0 for claimopen).
So, i would like to use a case statament or something which can help me get around this one.
Can someone please help me with any suggestions?
Thanks

this one please?

you can not use a single serial to send 2 commands simultaniously?
There is a single serial line so one command has to be before another. This doesnt mena that you can not read from 2 seperate threads but will have to ensure that there is a locking mechanism to make sure that your queries are atomic. In labview encapsulating all communications can be done with an action engine which will allow for concurrent execution with automatic blocking of your resource (serial device).

How to use multiple tables in developing one Graph in Endeca Integrator

We have the requirement where we want to show the matrix for a particular entity which is coming from two separate table, there is a join which is possible on both the tables to get the correct data. But we are not able to find how to use data from two tables. We can create the SQL query with all the joining conditions but there are many tables which are involved so performance of query will be a problem. Is there any way in Endeca where I can create two data sources using two separate queries and while showing the matrix , I can join both the tables to get the matrix .

You have not mentioned the version of Endeca that is used for your application. Joins are recently introduced in version 2.3 and could be used for avoiding complex DEFINE analytical statements. For this to work, the data should be present in the same dgraph and a single data source in Studio should point to data from both sources.
These may not yet be the type of SQL joins that you may expect them to be as performing complex joins is also costly in Endeca. Hope you are not expecting to join huge data sets.
The best possible solution I could think for addressing this problem is to load denormalized data (at least for now) into Endeca and do aggregations in queries. We can denormalize data in multiple ways even using ETL tools not just SQL queries as the above comment states.

How to use count sql statement?

i've never used the count function and i'm not sure how to use it to print it onto a html page...my code is below...

Class.forName("org.postgresql.Driver");
// create connection url
String URL2 = "jdbc:postgresql://dbhost/ug59sxn";
// pass database parameters to JDBC driver
Connection Conn2 = DriverManager.getConnection(URL2, "ug59sxn", "hupeswop");
// query statement
Statement SQLStatement2 = Conn2.createStatement();
// generate query
String Query2 = "SELECT COUNT(*) FROM userteam WHERE total > '"+total+"'";
// get result code
ResultSet SQLResult2 = SQLStatement2.executeQuery(Query2);

 Use the shorcuts on the left to visit different sections of the game.
You can change your squad around to prepare for forthcoming games (fixtures can be found in the statistics section),
transfer a player in to your squad to add some depth or replace injured members, or perhaps browse the statistics section to see how your team is doing in the FFL table.

You cannot cast a ResultSet object (or any other object for that matter) to a primitive (such as an int)
Replace the following line of code:
int position = (int)SQLResult2 + 1;with this:
int position = 0;
if(SQLResult2.next())
position = SQLResult2.getInt(1) + 1;
}Additionally I noticed that you have put single quotes around total in the following line:
String Query2 = "SELECT COUNT(*) FROM userteam WHERE total > '"+total+"'";Are you sure that the total column in the userteam table is of string type? If not, you don't need the single quotes.
