' sqltest.bas -- SQL Database Demo
'
' Demonstrates the SQL include library:
'   SQLOpen / SQLClose    - open and close a database
'   SQLExec               - execute non-query statements
'   SQLQuery / SQLNext    - run a query and iterate rows
'   SQLField$ / SQLFieldInt / SQLFieldDbl - read column values
'   SQLFieldCount / SQLFieldName$         - inspect result schema
'   SQLEof / SQLFreeResult / SQLAffected  - cursor and status
'   SQLError$             - error reporting
'
' Add sql.bas to your project, then click Run.
