Appendix B Frequently Asked Questions

When attempting to pass information to an Excel spreadsheet, it the
following ODBC Driver Error can occur: 'The query is not updateable
because it contains no searchable columns to use as a hopeful key'. The
Excel ODBC driver cannot correctly interpret the data type of a column, if
the column in the spreadsheet contains both text and numbers.
If a spreadsheet has been set up with data directly inputted in Excel and
an attempting to write new data to the spreadsheet from CX-Supervisor
this error will occur. This is because the ODBC Driver sees different
formats in a column.
To overcome this set up the spreadsheet the data area definition to
contain only the column headings (Insert | Name | Define…).
Another problem in this area has been that the format of the data can
change from 'Number' to 'Text' (i.e. '333) formats in the cell of the
spreadsheet. The exact cause of this error is unknown, but can be
resolved by clearing the cell formats (Edit | Clear | Formats) of the
spreadsheet that will be receiving the data.
