Multiple parameter values

问题

I have a problem with BIRT when I try to pass multiple values from report parameter.

I'm using BIRT 2.6.2 and eclipse.

I'm trying to put multiple values from cascading parameter group last parameter "JDSuser". The parameter is allowed to have multiple values and I'm using list box.

In order to be able to do that I'm writing my sql query with where-in statement where I replace text with javascript. Otherwise BIRT sql can't get multiple values from report parameter.

My sql query is

select jamacomment.createdDate, jamacomment.scopeId,
jamacomment.commentText, jamacomment.documentId,
jamacomment.highlightQuote, jamacomment.organizationId,
jamacomment.userId, 
organization.id, organization.name,
userbase.id, userbase.firstName, userbase.lastName,
userbase.organization, userbase.userName,
document.id, document.name, document.description,
user_role.userId, user_role.roleId,
role.id, role.name

from jamacomment jamacomment left join
userbase on userbase.id=jamacomment.userId
left join organization on
organization.id=jamacomment.organizationId
left join document on
document.id=jamacomment.documentId
left join user_role on
user_role.userId=userbase.id
right join role on
role.id=user_role.roleId

where jamacomment.scopeId=11
and role.name in ( 'sample grupa' )
and userbase.userName in ( 'sample' )

and my javascript code for that dataset on beforeOpen state is:

if( params["JDSuser"].value[0] != "(All Users)" ){
this.queryText=this.queryText.replaceAll('sample grupa', params["JDSgroup"]);
var users = params["JDSuser"];
//var userquery = "'";
var userquery = userquery + users.join("', '");
//userquery = userquery + "'";
this.queryText=this.queryText.replaceAll('sample', userquery);
}

I tryed many different quote variations, with this one I get no error messages, but if I choose 1 value, I get no data from database, but if I choose at least 2 values, I get the last chosen value data.

If I uncomment one of those additional quote script lines, then I get syntax error like this:

The following items have errors: Table (id = 597): + An exception occurred during processing. Please see the following message for details: Failed to prepare the query execution for the data set: Organization Cannot get the result set metadata. org.eclipse.birt.report.data.oda.jdbc.JDBCException: SQL statement does not return a ResultSet object. SQL error #1:You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'rudolfs.sviklis', 'sample' )' at line 25 ; com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'rudolfs.sviklis', 'sample' )' at line 25

Also, I should tell you that i'm doing this by looking from working example. Everything is the same, the previous code resulted to the same syntax error, I changed it to this script which does the same. The example is available here: http://developer.actuate.com/community/forum/index.php?/files/file/593-default-value-all-with-multi-select-parsmeter/

If someone could give me at least a clue to what I should do that would be great.

回答1:

You should always use the value property of a parameter, i.e.:

var users = params["JDSuser"].value;

It is not necessary to surround "userquery" with quotes because these quotes are already put in the SQL query arround 'sample'. Furthermore there is a mistake because userquery is not yet defined at line:

var userquery = userquery + users.join("', '");

This might introduce a string such "null" in your query. Therefore remove all references to userquery variable, just use this expression at the end:

this.queryText=this.queryText.replaceAll('sample', users.join("','"));

Notice i removed the blank space in the join expression. Finally once it works finely, you probably need to make your report input more robust by testing if the value is null:

if( params["JDSuser"].value!=null && params["JDSuser"].value[0] != "(All Users)" ){
  //Do stuff...

}
