java.lang.Object | +--interbase.interclient.ResultSet
Represents a cursor for the results of a SQL query.
A ResultSet provides access to a table of data. A ResultSet object is usually generated by executing a Statement.
A ResultSet maintains a cursor pointing to its current row of data. Initially the cursor is positioned before the first row. The 'next' method moves the cursor to the next row.
The getXXX methods retrieve column values for the current row. You can retrieve values either using the index number of the column, or by using the name of the column. In general using the column index will be more efficient. Columns are numbered from 1.
For maximum portability, ResultSet columns within each row should be read in left-to-right order and each column should be read only once.
For the getXXX methods, the JDBC driver attempts to convert the underlying data to the specified Java type and returns a suitable Java value. See the JDBC specification for allowable mappings from SQL types to Java types with the ResultSet.getXXX methods.
Column names used as input to getXXX methods are case insensitive. When performing a getXXX using a column name, if several columns have the same name, then the value of the first matching column will be returned. The column name option is designed to be used when column names are used in the SQL query. For columns that are NOT explicitly named in the query, it is best to use column numbers. If column names were used there is no way for the programmer to guarantee that they actually refer to the intended columns.
A ResultSet is automatically closed by the Statement that generated it when that Statement is closed, re-executed, or is used to retrieve the next result from a sequence of multiple results.
The number, types and properties of a ResultSet's columns are provided by the ResulSetMetaData object returned by the getMetaData method.
InterClient note: As stated in the specification above "ResultSet columns within each row should be read in left-to-right order and each column should be read only once." This reflects implementation limitations in some underlying database protocols. The current version of InterClient supports random access of result columns. However, future versions may not have this capability by default in order to leverage any performance advantages that may come with sequential-only access. So in the future, random access may require setting a connection property to enable this behavior. Please send mail to mailto:interclient@interbase.com if you have an opinion about this behavior.

protected void finalize()
throws Throwable
Therefore, it is recommended that result sets be explicitly closed even when your application throws an exception. This can be achieved by placing a call to close() in a finally clause of your application as follows
try {
...
}
finally {
if (resultSet != null)
try { resultSet.close (); } catch (SQLException ohWell) {}
if (statement != null)
try { statement.close (); } catch (SQLException ohWell) {}
if (connection != null)
try { connection.close (); } catch (SQLException ohWell) {}
}
Or alternatively, use the new System.runFinalizersOnExit(true) method in Java 1.1 or later.
public boolean next()
throws SQLException
If an input stream from the previous row is open, it is implicitly closed. The ResultSet's warning chain is cleared when a new row is read.
InterClient note: InterClient allows for interleaved calls to next() on two separate result sets.
public void close()
throws SQLException
Note: A ResultSet is automatically closed by the Statement that generated it when that Statement is closed, re-executed, or is used to retrieve the next result from a sequence of multiple results. A ResultSet is also automatically closed when it is garbage collected.

public SQLWarning getWarnings()
throws SQLException

public void clearWarnings()

public String getCursorName()
throws SQLException
In SQL, a result table is retrieved through a cursor that is named. The current row of a result can be updated or deleted using a positioned update/delete statement that references the cursor name. To insure that the cursor has the proper isolation level to support update, the cursor's select statement should be of the form 'select for update'. If the 'for update' clause is omitted the positioned updates may fail.
JDBC supports this SQL feature by providing the name of the SQL cursor used by a ResultSet. The current row of a ResultSet is also the current row of this SQL cursor.
Note: If positioned update is not supported a SQLException is thrown
public ResultSetMetaData getMetaData()
throws SQLException
public Object getObject(int column)
throws SQLException
This method will return the value of the given column as a Java object. The type of the Java object will be the default Java object type corresponding to the column's SQL type, following the mapping for built-in types specified in the JDBC spec.
This method may also be used to read datatabase specific abstract data types.
JDBC 2.0 note:
New behavior for getObject().
The behavior of method getObject() is extended to materialize
data of SQL user-defined types. When the column columnIndex is
a structured or distinct value, the behavior of this method is as
if it were a call to:
getObject(columnIndex, this.getStatement().getConnection().getTypeMap())
columnIndex - the first column is 1, the second is 2, ...

public boolean absolute(int row)
throws SQLException
If row is positive, moves to an absolute row with respect to the beginning of the result set. The first row is row 1, the second is row 2, etc.
If row is negative, moves to an absolute row position with respect to the end of result set. For example, calling absolute(-1) positions the cursor on the last row, absolute(-2) indicates the next-to-last row, etc.
An attempt to position the cursor beyond the first/last row in the result set, leaves the cursor before/after the first/last row, respectively.
Note: Calling absolute(1) is the same as calling first(). Calling absolute(-1) is the same as calling last().
public boolean relative(int rows)
throws SQLException
Note: Calling relative(1) is different than calling next() since is makes sense to call next() when there is no current row, for example, when the cursor is positioned before the first row or after the last row of the result set.
public boolean previous()
throws SQLException
Note: previous() is not the same as relative(-1) since it makes sense to call previous() when there is no current row.
