Answer 1

You can open two connections. One to SQL Server (you can use a thin or JDBC-ODBC bridge), the other to your Excel spreadsheet using the JDBC-ODBC bridge. You could query the SQL Server database, massage and format your data, then write it to Excel. Excel works with a very limited set of SQL. Here is a program from a post by Tim Vickers that others sounded happy to have. I'm reposting here for your convenience. I have not personally run this program, so please use it at your own risk.
import java.sql.*;
import java.io.*;
import java.util.*;
import java.text.*;
* Name: Excel.java
* Purpose: To demonstrate how to use ODBC and Excel to create
* a table,
* insert data into it, and select it back out.
* Version: Developed using JDK 1.3, but also works with JDK
* 1.2.2
* Instructions:
* 1) Create a new Excel spreadsheet
* 2) Create a new ODBC data source that points to this
* spreadsheet
* a) Go to Control Panel
* b) Open "ODBC Data sources (32-bit) (wording may be
* slightly
* different for different platforms)
* c) Under "User DSN" tab, press "Add" button
* d) Select the "Microsoft Excel Driver (*.xls)" and
* press
* "Finish" button
* e) Enter "Data Source Name" of "TestExcel"
* f) Press "Select Workbook" button
* g) Locate and select the spreadsheet you created in
* Step 1
* h) Unselect the "Read Only" checkbox
* i) Press "Ok" button
* 3) Compile and run Excel.java
* 4) Open Excel spreadsheet and you will find a newly
* created
* sheet, GOOD_DAY, with three rows of data.
* Notes:
* If you want to select data from a spreadsheet that was
* NOT
* created via JDBC-ODBC (i.e. you entered data manually
* into
* a spreadsheet and want to select it out), you must
* reference
* the sheet name as "[sheetname$]".
* When you create the table and insert the data using
* Java, you
* must reference the sheet name as "sheetname".
* Also, do not have the spreadsheet open when you are
* running
* the program. You can get locking conflicts.
