Reading and writing dates and times Description This set of examples shows how to work with date and time data types when accessing data in spreadsheets and databases.
The basic model version uses an ODBC connection to databases through the odbc driver, model version (2) uses ODBC through SQL statements and version (4) shows the same for Oracle databases accessed via the OCI. Model versions (3) and (5) work with different spreadsheet drivers, and version (6) with CSV data format. Further explanation of this example: Xpress Whitepaper 'Using ODBC and other database interfaces with Mosel', Section Examples - Handling dates and time.
