	I have problems modifying my SQL query on a report. The table fields that are supposed to be linked have different datatypes. I cleared all links from the database expert and on the Record Selection Formula inserted these to link the fields: {T3772400.CPEDIDOS} = {TB080500.CPROPUES} + {TB080500.CINDPEDI} and {T3772400.CEMPRESA} = Mid({TB080500.CEMPRESA},2,2) But my SQL query result remains two separate tables...

	You will probably have to use a Command to write the whole SQL to get your data instead of using the tables directly in Crystal. What type of database are you connecting to? Crystal doesn't allow commands for all of them, but will for the "standards" - MS SQL Server (through an OLE DB connection - I'm not sure if it's available on an ODBC connection), Oracle, etc. To see if it's available for your database, open your report and then open the database connection. If you see "Add Command" just under the database name, then you can write your own SQL to get the report data. -Dell -Dell

	Thanks! I am using DB2 and an ODBC connection and was able to use add command and create my own query.

	Now I have a new problem using command and writing the SQL query... I am unable to specify parameters. I read how to solve it with a function: http://forums.devarticles.com/net-development-43/crystal-reports-custom-sql-query-parameter-passing-7663.html Is this the cleanest way of solving the parameters issue?

	Actually, you can specify parameters. - Remove any existing parameters in your report that you want to use in the SQL. - In the window where you enter the SQL for the command, you have an option for creating parameters. Create the parameters that you want to use in the SQL. - In the SQL, use Crystal syntax for the parameters instead of the syntax for your database - e.g., "where mytable.myfield = {?parametername}". -Dell
