or CSV connections only one option is available, namely ‘SQL Text’. For
convenience, a facility is provided for automatically building the required SQL
Text for this type of connection. This facility is invoked from the ‘Build SQL...’
button shown below:
This will bring up a dialog with a list of all valid files in the ‘Directory’ specified for the Connection.
After choosing a file and exiting from the ‘Build SQL’ dialog the required SQL Text is built. In the
above example, the file ‘Tables.txt’ was chosen, but this will be written as Tables#txt in the SQL
Text as most Providers will not accept the ‘.’ character, because it is used as a delimiter.
Source
The source field shows the Table name, Server Query or SQL text as selected above which the
Recordset is linked to.
Automatically open on connection
