Allows you to turn fetching on or off or to use the ALWAYS value to prefetch the cursor results, even for SENSITIVE cursor types and for cursors that involve a proxy table.
For the catalog store only, PREFETCH controls whether rows are fetched to the client side before being made available to the client application. Fetching a number of rows at a time, even when the client application requests rows one at a time (for example, when looping over the rows of a cursor) minimizes response time and improves overall throughput by limiting the number of requests to the database.
The setting of PREFETCH is ignored by Open Client and JDBC connections, and for the IQ store.
