  +--interbase.interclient.ResultSet

public final class ResultSet
extends Object
implements ResultSet, Adaptor, borland.jdbc.SQLAdapter, com.inprise.sql.SQLAdapter

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.

Method Detail

finalize

protected void finalize()
                 throws Throwable

A result set will be closed when its finalizer is called by the garbage collector. However, there is no guarantee that the garbage collector will ever run, and in general will not run when an application terminates abruptly without closing its resources.

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

A ResultSet is initially positioned before its first row; the first call to next makes the first row the current row; the second call makes the second row the current row, etc.

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.

Specified by:: next in interface ResultSet

Returns:: true if the new current row is valid; false if there are no more rows
Throws:: SQLException - if a database access error occurs.
Since:: JDBC 1

close

public void close()
           throws SQLException

In some cases, it is desirable to immediately release a ResultSet's database and JDBC resources instead of waiting for this to happen when it is automatically closed; the close method provides this immediate release.

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.

Specified by:: close in interface ResultSet

Throws:: SQLException - if a database access error occurs.
Since:: JDBC 1

wasNull

public boolean wasNull()
                throws SQLException

A column may have the value of SQL NULL; wasNull reports whether the last column read had this special value. Note that you must first call getXXX on a column to try to read its value and then call wasNull() to find if the value was the SQL NULL.

Specified by:: wasNull in interface ResultSet

getCursorName

public String getCursorName()
                     throws SQLException

Get the name of the SQL cursor used by this ResultSet.

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

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.

Specified by:: relative in interface ResultSet

Returns:: true if on a row, false otherwise.
Throws:: SQLException - if a database access error occurs, or there is no current row, or result set type is TYPE_FORWARD_ONLY.
Since:: JDBC 2, not yet supported

public boolean previous()

refreshRow

public void refreshRow()
                throws SQLException

Refresh the value of the current row with its current value in the database. Cannot be called when on the insert row. The refreshRow() method provides a way for an application to explicitly tell the JDBC driver to refetch a row(s) from the database. An application may want to call refreshRow() when caching or prefetching is being done by the JDBC driver to fetch the latest value of a row from the database. The JDBC driver may actually refresh multiple rows at once if the fetch size is greater than one. All values are refetched subject to the transaction isolation level and cursor sensitivity. If refreshRow() is called after calling updateXXX(), but before calling updateRow() then the updates made to the row are lost. Calling refreshRow() frequently will likely slow performance.

Specified by:: refreshRow in interface ResultSet

Throws:: SQLException - if a database access error occurs, or if called when on the insert row.
Since:: JDBC 2, not yet supported

moveToInsertRow

public void moveToInsertRow()
                     throws SQLException

Move to the insert row. The current cursor position is remembered while the cursor is positioned on the insert row. The insert row is a special row associated with an updatable result set. It is essentially a buffer where a new row may be constructed by calling the updateXXX() methods prior to inserting the row into the result set. Only the updateXXX(), getXXX(), and insertRow() methods may be called when the cursor is on the insert row. All of the columns in a result set must be given a value each time this method is called before calling insertRow(). UpdateXXX()must be called before getXXX() on a column.

Specified by:: moveToInsertRow in interface ResultSet

Throws:: SQLException - if a database access error occurs, or the result set is not updatable
