Specifies the number of rows of data the driver attempts to fetch for each ODBC call.
Valid Values
0 | x
where:
x
is a positive integer from 1 to 2147483647 that defines a number of rows.
Behavior
If set to 0, the driver attempts to fetch up to a maximum of 2147483647 rows. This value typically provides the maximum throughput.
If set to x, the driver attempts to fetch up to a maximum of the specified number of rows. Setting the value lower than 1000000 can reduce the response time for returning the initial data. Consider using a smaller WSFetch Size for interactive applications only.
Notes
WSFetchSize and FetchSize can be used to adjust the trade-off between throughput and response time. Smaller fetch sizes can improve the initial response time of the query. Larger fetch sizes can improve overall response times at the cost of additional memory.
