Spreadsheets and databases: working with multiple data tables and arrays

Description

A database table (or a spreadsheet range) may contain in its different fields (columns) the data for several Mosel arrays and inversely, a Mosel array may correspond to several data tables (ranges). We have here examples of various different cases:

using the odbc driver,
formulated with SQL statements,
using the excel driver,
using the oci driver,
using the xls driver, and
using the csv driver.

for three sets of examples:

Reading several arrays from a single database table/spreadsheet range (multicol.mos)
Outputting several arrays into a single database table/spreadsheet range (multiout.mos)
Reading an array from several tables/ranges (multitab.mos)

Further explanation of this example: Xpress Whitepaper 'Using ODBC and other database interfaces with Mosel', Section 'Examples'.
