change query depending on locale [solved] [message #1223515]

Hi

I'm trying to modify the SQL query for a Chart depending on the locale. What I get so far :

beforeFactory

var mylocale=reportContext.getLocale().toString().substr(1,2)

But I'm stuck on retrieving the parameter and inserting on the query. Something like this:

Select * from table where country=' + param["mylocale"] + '

Any help would be much appreciated

I don't think it is necessary to use a report parameter such "mylocale" here. You could try this:

In the query of your dataset, use a question mark like this:

Select * from table where country=?

Then in parameters section of the dataset, edit the parameter and just fill the "Default value" property with the expression you mentionned:

reportContext.getLocale().toString().substr(1,2)

I hope this helps!

Hi donino

i'm afraid I gave a wrong example.
The real query is more a thing like this:

If locale is French, select French_name, french_description from product

If locale is English, select englîsh_name, english_description from product

I can get the locale but I'm stuck on getting the proper SQL to work in the dataset

Thanks in advance

In this case you need to change your query depending on the value of the locale. In the beforeOpen script of the dataset. You probably need to use aliases so that BIRT can still match columns dataset with the result of the query. It would be something like:

var mylocale=reportContext.getLocale().toString().substr(1,2);
if (mylocale=="fr"){
    this.queryText="select French_name as name, french_description as description from product";
}else if(mylocale=="en"){
    this.queryText="select englîsh_name as name, english_description as description from product";
}

Let me know if it helps

Jose,
You could use something like this in the beforeOpen() of the data source

var locale = reportContext.getLocale().toString()
locale = locale.substr(3,4);

this.queryText = "select * from customers where country = '" + locale + "'";
