subreport

2003-07-17 08:13

i have a question:

i had 2 tablemodel in my report, so i use subreport to realize.

i want to use a condition to choose the data from table.

i read the example of subreport in the JasperReport.

i see we define subparameter in the master-report : City $F{city}

in sub-report: $P{city}

for bind the data to use SQL:select * from * where city = $P{city}

 

but here for me, i only use 2 tablemodels not database.

so i cant use "select" to bind the data.

i cant know how to define subparameter?

 

ps:for example_2 tables defined by me,

there are a column "city" in each table.

i want to choose the data by "city" , use groups for realize.

 

 

thanks
