Examples of org.h2.result.LocalResult

org.h2.result.LocalResult
A local result set contains all row data of a result set. This is the object generated by engine, and it is also used directly by the ResultSet class in the embedded mode. If the result does not fit in memory, it is written to a temporary file.
