Interface ResultSet

public interface ResultSet

A table of data representing a database result set, which is usually generated by executing a statement that queries the database.

A ResultSet object 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, and because it returns false when there are no more rows in the ResultSet object, it can be used in a while loop to iterate through the result set.

A default ResultSet object is not updatable and has a cursor that moves forward only. Thus, it is possible to iterate through it only once and only from the first row to the last row. New methods in the JDBC 2.0 API make it possible to produce ResultSet objects that are scrollable and/or updatable. The following code fragment, in which con is a valid Connection object, illustrates how to make a result set that is scrollable and insensitive to updates by others, and that is updatable. See ResultSet fields for other options.


       Statement stmt = con.createStatement(
                                      ResultSet.TYPE_SCROLL_INSENSITIVE,
                                      ResultSet.CONCUR_UPDATABLE);
       ResultSet rs = stmt.executeQuery("SELECT a, b FROM TABLE2");
       // rs will be scrollable, will not show changes made by others,
       // and will be updatable

The ResultSet interface provides getXXX methods for retrieving column values from the current row. Values can be retrieved using either the index number of the column or the name of the column. In general, using the column index will be more efficient. Columns are numbered from 1. For maximum portability, result set columns within each row should be read in left-to-right order, and each column should be read only once.

For the getXXX methods, a JDBC driver attempts to convert the underlying data to the Java type specified in the XXX part of the getXXX method and returns a suitable Java value. The JDBC specification has a table showing the 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 a getXXX method is called with a column name and several columns have the same name, 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 that generated the result set. For columns that are NOT explicitly named in the query, it is best to use column numbers. If column names are used, there is no way for the programmer to guarantee that they actually refer to the intended columns.

A set of updateXXX methods were added to this interface in the JDBC 2.0 API (Java^TM 2 SDK, Standard Edition, version 1.2). The comments regarding parameters to the getXXX methods also apply to parameters to the updateXXX methods.

The updateXXX methods may be used in two ways:

to update a column value in the current row. In a scrollable ResultSet object, the cursor can be moved backwards and forwards, to an absolute position, or to a position relative to the current row. The following code fragment updates the NAME column in the fifth row of the ResultSet object rs and then uses the method updateRow to update the data source table from which rs was derived.
```
       rs.absolute(5); // moves the cursor to the fifth row of rs
       rs.updateString("NAME", "AINSWORTH"); // updates the 
          // NAME column of row 5 to be AINSWORTH
       rs.updateRow(); // updates the row in the data source

 
```

to insert column values into the insert row. An updatable ResultSet object has a special row associated with it that serves as a staging area for building a row to be inserted. The following code fragment moves the cursor to the insert row, builds a three-column row, and inserts it into rs and into the data source table using the method insertRow.


       rs.moveToInsertRow(); // moves cursor to the insert row
       rs.updateString(1, "AINSWORTH"); // updates the 
          // first column of the insert row to be AINSWORTH
       rs.updateInt(2,35); // updates the second column to be 35
       rs.updateBoolean(3, true); // updates the third row to true
       rs.insertRow();
       rs.moveToCurrentRow();

A ResultSet object is automatically closed when the Statement object that generated it is closed, re-executed, or used to retrieve the next result from a sequence of multiple results.

The number, types and properties of a ResultSet object's columns are provided by the ResulSetMetaData object returned by the ResultSet.getMetaData method.

Method Detail

public boolean next()
             throws SQLException

Moves the cursor down one row from its current position. A ResultSet cursor is initially positioned before the first row; the first call to the method next makes the first row the current row; the second call makes the second row the current row, and so on.

If an input stream is open for the current row, a call to the method next will implicitly close it. A ResultSet object's warning chain is cleared when a new row is read.

Returns:: true if the new current row is valid; false if there are no more rows
Throws:: SQLException - if a database access error occurs

close

public void close()
           throws SQLException

Releases this ResultSet object's database and JDBC resources immediately instead of waiting for this to happen when it is automatically closed.

Note: A ResultSet object is automatically closed by the Statement object that generated it when that Statement object is closed, re-executed, or is used to retrieve the next result from a sequence of multiple results. A ResultSet object is also automatically closed when it is garbage collected.

Throws:: SQLException - if a database access error occurs

wasNull

public boolean wasNull()
                throws SQLException

Reports whether the last column read had a value of SQL NULL. Note that you must first call one of the getXXX methods on a column to try to read its value and then call the method wasNull to see if the value read was SQL NULL.

Returns:: true if the last column value read was SQL NULL and false otherwise
Throws:: SQLException - if a database access error occurs

getString

public String getString(int columnIndex)
                 throws SQLException

Gets the value of the designated column in the current row of this ResultSet object as a String in the Java programming language.

getCursorName

public String getCursorName()
                     throws SQLException

Gets the name of the SQL cursor used by this ResultSet object.

In SQL, a result table is retrieved through a cursor that is named. The current row of a result set 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.

The JDBC API supports this SQL feature by providing the name of the SQL cursor used by a ResultSet object. The current row of a ResultSet object is also the current row of this SQL cursor.

Note: If positioned update is not supported, a SQLException is thrown.

Returns:: the SQL name for this ResultSet object's cursor

This method may also be used to read datatabase-specific abstract data types. In the JDBC 2.0 API, the behavior of method getObject is extended to materialize data of SQL user-defined types. When a column contains a structured or distinct value, the behavior of this method is as if it were a call to: getObject(columnIndex, this.getStatement().getConnection().getTypeMap()).

Parameters:: columnIndex - the first column is 1, the second is 2, ...
Returns:: a java.lang.Object holding the column value
Throws:: SQLException - if a database access error occurs
