Statement attributes are characteristics of the statement. For example, whether to use bookmarks and what kind of cursor to use with the statement’s result set are statement attributes.
Statement attributes are set with SQLSetStmtAttr
and their current settings retrieved with
SQLGetStmtAttr
. There is no requirement that an application set any statement attributes; all
statement attributes have defaults, some of which are driver-specific.
When a statement attribute can be set depends on the attribute itself. The
Concurrency
, CursorType,
SimulateCursor, and
UseBookmarsstatement attributes must be set before the statement is executed. The
AsyncEnableand
NoScanstatement attributes can be set at any time but are not applied until the statement is used again.
MaxLength,
MaxRows, and
QueryTimeout` statement attributes can be set at any time, but it is driver-specific whether
they are applied before the statement is used again. The remaining statement attributes can be
set at any time.
