I am using the crystal reports web server. i want to know the limitations for the crystal reports.

-  is it possibile that we can work with temporary tables in the report we create in SQL server. what i want to do is that each report generated on the web should contain its own temporary data stored with the report and send to the client. i want to generate some MIS reports which require some database processing and i can not use permanent temporary tables in SQL server  where multiple users are coming simultaniously. any alternative suggestion about this will be appriciated.


- can we dinamically generate the crystal report on the web and then have it send to the client.


If some body send me links to the web for the resources then i will really appriciate fo that.

You cannot store data in a report dynamically at runtime. What you can do is dynamically create your temp tables with variable names, then design your report around an alias. Pass the name of the particular dynamic temp table to the datasource alias to avoid file conflicts, or user collisions.

As far as it goes, create a table as a template, Create report around it. Then pass your relavent table name at runtime to Crpe component.

Crystal never uses ACTUAL tables for anything. It creates an array of alias and table name information. This is stored in the table property of the crpe component. You can view this list and change items in the itemindex of the tables property at runtime.

As for actual code for changing this in a standalone CR setup, couldn't tell you, as I do all this in Delphi which really won't help you. My DRRYAN could tell you more as far as making the change in CR itself at runtime.

I am creating a application using Delphi , Interbase and Crystal report 8.5. I would like to know the procedure or website describing how to create report dynamically using variables from delphi. that is the report content should be generated at the runtime using the variables.

I heard that this can be done by using RDC and RCAPI calls.... if some boda can explain with the code it will be very helpfull for me ..
