Limitations and Requirements
Note
During normal selection or import of an entire table, you may encounter an error indicating a problem with a specific column. Since some tables require filtering based on a particular column, data from them can only be ingested using custom SQL statements. In this case, the problematic column can be used as a filter in the WHERE clause of a custom SQL statement to ingest the table.
For more information, please consult the CData driver documentation for the specific table.
For more information on using custom SQL, see Create Dataset with SQL.
Note
For filtering date columns, this connection type supports a set of literal functions on dates. You can use these to reduce the volume of data extracted from the database using a custom SQL query. For more information, see the pg_dateliteralfunctions.htm
page in the driver documentation for this connection type.
Supports authentication using AWS key and secret.
