Class ResultSetWrapper
- All Implemented Interfaces:
AutoCloseable,ResultSet,Wrapper
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 (JavaTM 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
ResultSetobject, 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 theNAMEcolumn in the fifth row of theResultSetobjectrsand then uses the methodupdateRowto update the data source table from whichrswas derived.rs.absolute(5); // moves the cursor to the fifth row of rs rs.updateString("NAME", "AINSWORTH"); // updates the //NAMEcolumn of row 5 to beAINSWORTHrs.updateRow(); // updates the row in the data source - to insert column values into the insert row. An updatable
ResultSetobject 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 intorsand into the data source table using the methodinsertRow.rs.moveToInsertRow(); // moves cursor to the insert row rs.updateString(1, "AINSWORTH"); // updates the // first column of the insert row to beAINSWORTHrs.updateInt(2,35); // updates the second column to be35rs.updateBoolean(3, true); // updates the third row totruers.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.

getCursorName
Gets the name of the SQL cursor used by thisResultSetobject.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
selectstatement 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
ResultSetobject. The current row of aResultSetobject is also the current row of this SQL cursor.Note: If positioned update is not supported, a
SQLExceptionis thrown.- Specified by:

nextin interfaceResultSet- Returns:
trueif the new current row is valid;falseif there are no more rows- Throws:
SQLException- if a database access error occurs
-
close
Releases thisResultSetobject's database and JDBC resources immediately instead of waiting for this to happen when it is automatically closed.Note: A
ResultSetobject is automatically closed by theStatementobject that generated it when thatStatementobject is closed, re-executed, or is used to retrieve the next result from a sequence of multiple results. AResultSetobject is also automatically closed when it is garbage collected.- Specified by:

absolute
Moves the cursor to the given row number in thisResultSetobject.If the row number is positive, the cursor moves to the given row number with respect to the beginning of the result set. The first row is row 1, the second is row 2, and so on.
If the given row number is negative, the cursor moves to an absolute row position with respect to the end of the result set. For example, calling the method
absolute(-1)positions the cursor on the last row; calling the methodabsolute(-2)moves the cursor to the next-to-last row, and so on.An attempt to position the cursor beyond the first/last row in the result set leaves the cursor before the first row or after the last row.
Note: Calling
absolute(1)is the same as callingfirst(). Callingabsolute(-1)is the same as callinglast().- Specified by:
absolutein interfaceResultSet- Parameters:
row- the row to move to- Returns:
trueif the cursor is on the result set;falseotherwise- Throws:
SQLException- if a database access error occurs, the row is0, or the result set type isTYPE_FORWARD_ONLY- Since:

refreshRow
Refreshes the current row with its most recent value in the database. This method cannot be called when the cursor is on the insert row.The
refreshRowmethod 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 callrefreshRowwhen 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
refreshRowis called after calling anupdateXXXmethod, but before calling the methodupdateRow, then the updates made to the row are lost. Calling the methodrefreshRowfrequently will likely slow performance.- Specified by:

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 theupdateXXXmethods prior to inserting the row into the result set. Only theupdateXXX,getXXX, andinsertRowmethods 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 callinginsertRow. AnupdateXXXmethod must be called before agetXXXmethod can be called on a column value.- Specified by:
