Variants

FetchArraySize(u32)

The array size used for performing fetches.

This specifies the number of rows allocated before performing fetches. The default value is 100. Higher value reduces the number of network round trips to fetch rows but requires more memory. The preferable value depends on the query and the environment.

If the query returns only onw row, you should use StmtParam::FetchArraySize(1).

Tag(String)

Reserved for when statement caching is supported.

Scrollable

Reserved for when scrollable cursors are supported.
