SUMMARY: INNER | FIELD | CONSTR | METHOD | DETAIL: FIELD | CONSTR | METHOD |
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.

The first warning reported by calls on this ResultSet is returned. Subsequent ResultSet warnings will be chained to this SQLWarning.
The warning chain is automatically cleared each time a new row is read.
Note: This warning chain only covers warnings caused by ResultSet methods. Any warning caused by statement methods (such as reading OUT parameters) will be chained on the Statement object.
public void clearWarnings() throws SQLException
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 columnIndex) throws SQLException
Get the value of a column in the current row as a Java object.
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 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()).

public boolean isBeforeFirst() throws SQLException
Determine if the cursor is before the first row in the result set.
public boolean isAfterLast() throws SQLException
Determine if the cursor is after the last row in the result set.
public boolean isFirst() throws SQLException
Determine if the cursor is on the first row of the result set.
public boolean isLast() throws SQLException
Determine if the cursor is on the last row of the result set. Note: Calling isLast() may be expensive since the JDBC driver might need to fetch ahead one row in order to determine whether the current row is the last row in the result set.
public void beforeFirst() throws SQLException
Moves to the front of the result set, just before the first row. Has no effect if the result set contains no rows.
public void afterLast() throws SQLException
Moves to the end of the result set, just after the last row. Has no effect if the result set contains no rows.
public boolean first() throws SQLException
Moves to the first row in the result set.
public boolean last() throws SQLException
Moves to the last row in the result set.
public int getRow() throws SQLException
Determine the current row number. The first row is number 1, the second number 2, etc.
public boolean absolute(int row) throws SQLException
Move to an absolute row number in the result set.
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
Moves a relative number of rows, either positive or negative. Attempting to move beyond the first/last row in the result set positions the cursor before/after the the first/last row. Calling relative(0) is valid, but does not change the cursor position.
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
Moves to the previous row in the result set.
Note: previous() is not the same as relative(-1) since it makes sense to call previous() when there is no current row.
