java.lang.Objectorg.experlog.db.DummyStatement
public class DummyStatement
A Statement object is used for executing a static SQL statement and obtaining the results produced by it.
Only one ResultSet per Statement can be open at any point in time. Therefore, if the reading of one ResultSet is interleaved with the reading of another, each must have been generated by different Statements. All statement execute methods implicitly close a statment's current ResultSet if an open one exists.

Method Summary | ||
---|---|---|
void |
addBatch(java.lang.String sql)
|
|
void |
cancel()
Cancel can be used by one thread to cancel a statement that is being executed by another thread. |
|
void |
clearBatch()
|
|
void |
clearWarnings()
After this call, getWarnings returns null until a new warning is reported for this Statement. |
|
void |
close()
In many cases, it is desirable to immediately release a Statements's database and JDBC resources instead of waiting for this to happen when it is automatically closed; the close method provides this immediate release. |
