Dynamic Sql query in birt [message #548764]

Thu, 22 July 2010 18:20

I have a scenario where I need to create sql query dynamically based on table columns.

That is, I am passing in a 'report id' as parameter to query.....then query fetches all 'report parameters' for that report id and gets 'report details' for each of the report parameter. The problem is report details table should be picked dynamically based on the 'report level' column in the report param table.
for example:
if value for 'report level'= ABC in reportparam table, then details table is ABC_report_detals and so on.

is there any way i can do it with property binder?

Any help much appreciated!

Do all the report parameter detail tables have the same name and number
of columns?

yes, all param details tables have exactly same column names (atleast for the columns i need information from)

You should be able to do this with a beforeOpen script on the dataset.
Something like:
this.queryText = "Select * from " +
params["parmtable"].value+"_report_details";

yes i could...but whats confusing is that params["parmtable"].value is determined by another column in report_params table..

report_params table has a column named 'report_level' ....so on a high-level the query has to be something like:

A 'report' has many report-params and for each report-param do the following:
if report_level= 'ABC' then select from table 'ABC_details'
if report_level ='XYZ' then select from table 'XYZ_details' and so on

so how can i set that condition for a parameter?

You could do this with nested tables. Take a look at the attached
example. It does not change the table but that should be doable with
the same scheme.
