Variable
maxrows - Limits the size of query results.
Description
The ${maxrows} variable can be used to limit the number of rows returned
by any individual query in a batch of SQL (the default is 500). A value
of zero or less indicates that query result sizes should be unlimited.
For certain display styles (see style), query results are retained entirely in memory so it is important the results not be unbounded.
