See Also:: What Is in the JDBC 2.0 API

isLast

public boolean isLast()
               throws java.sql.SQLException

Indicates whether the cursor is on the last row of this ResultSet object. Note: Calling the method isLast may be expensive because 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.

Specified by:: beforeFirst in interface java.sql.ResultSet

Throws:: java.sql.SQLException - if a database access error occurs or the result set type is TYPE_FORWARD_ONLY
Since:: 1.2
See Also:: What Is in the JDBC 2.0 API

afterLast

public void afterLast()
               throws java.sql.SQLException

Moves the cursor to the end of this ResultSet object, just after the last row. This method has no effect if the result set contains no rows.

Specified by:: afterLast in interface java.sql.ResultSet

Throws:: java.sql.SQLException - if a database access error occurs or the result set type is TYPE_FORWARD_ONLY
Since:: 1.2
See Also:: What Is in the JDBC 2.0 API

first

public boolean first()
              throws java.sql.SQLException

Moves the cursor to the first row in this ResultSet object.

Specified by:: first in interface java.sql.ResultSet

Returns:: true if the cursor is on a valid row; false if there are no rows in the result set

Since:: 1.2
See Also:: What Is in the JDBC 2.0 API

public boolean next()
             throws java.sql.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.

Specified by:: next in interface java.sql.ResultSet

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

public boolean previous()
                 throws java.sql.SQLException

Moves the cursor to the previous row in this ResultSet object.

Note: Calling the method previous() is not the same as calling the method relative(-1) because it makes sense to callprevious() when there is no current row.

Specified by:: previous in interface java.sql.ResultSet

Returns:: true if the cursor is on a valid row; false if it is off the result set
Throws:: java.sql.SQLException - if a database access error occurs or the result set type is TYPE_FORWARD_ONLY
Since:: 1.2
See Also:: What Is in the JDBC 2.0 API

getRow

public int getRow()
           throws java.sql.SQLException

Retrieves the current row number. The first row is number 1, the second number 2, and so on.

Specified by:: getRow in interface java.sql.ResultSet

Returns:: the current row number; 0 if there is no current row
Throws:: java.sql.SQLException - if a database access error occurs
Since:: 1.2
See Also:: What Is in the JDBC 2.0 API

absolute

public boolean absolute(int nRow)
                 throws java.sql.SQLException

Moves the cursor to the given row number in this ResultSet object.

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 method absolute(-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 calling first(). Calling absolute(-1) is the same as calling last().

Specified by:: absolute in interface java.sql.ResultSet

Returns:: true if the cursor is on the result set; false otherwise
Throws:: java.sql.SQLException - if a database access error occurs, the row is 0, or the result set type is TYPE_FORWARD_ONLY
Since:: 1.2
See Also:: What Is in the JDBC 2.0 API

relative

public boolean relative(int nRows)
                 throws java.sql.SQLException

Moves the cursor 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 the method relative(1) is different from calling the method next() because 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 java.sql.ResultSet

Returns:: true if the cursor is on a row; false otherwise
Throws:: java.sql.SQLException - if a database access error occurs, there is no current row, or the result set type is TYPE_FORWARD_ONLY
Since:: 1.2
See Also:: What Is in the JDBC 2.0 API

close

public void close()
           throws java.sql.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.

Specified by:: close in interface java.sql.ResultSet

Throws:: java.sql.SQLException - if a database access error occurs

wasNull

public boolean wasNull()
                throws java.sql.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.

Specified by:: wasNull in interface java.sql.ResultSet

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

getObject

public java.lang.Object getObject(int nColumnIndex)
                           throws java.sql.SQLException

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

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 specification.

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.

Specified by:: getCursorName in interface java.sql.ResultSet

refreshRow

public void refreshRow()
                throws java.sql.SQLException

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 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 an updateXXX method, but before calling the method updateRow, then the updates made to the row are lost. Calling the method refreshRow frequently will likely slow performance.

Specified by:: refreshRow in interface java.sql.ResultSet

Throws:: java.sql.SQLException - if a database access error occurs or if this method is called when the cursor is on the insert row
Since:: 1.2
See Also:: What Is in the JDBC 2.0 API

cancelRowUpdates

public void cancelRowUpdates()
                      throws java.sql.SQLException

Cancels the updates made to the current row in this ResultSet object. This method may be called after calling an updateXXX method(s) and before calling the method updateRow to roll back the updates made to a row. If no updates have been made or updateRow has already been called, this method has no effect.

Specified by:: cancelRowUpdates in interface java.sql.ResultSet

Throws:: java.sql.SQLException - if a database access error occurs or if this method is called when the cursor is on the insert row
Since:: 1.2
See Also:: What Is in the JDBC 2.0 API

moveToInsertRow

public void moveToInsertRow()
                     throws java.sql.SQLException

Moves the cursor 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. An updateXXX method must be called before a getXXX method can be called on a column value.

Specified by:: moveToInsertRow in interface java.sql.ResultSet

Throws:: java.sql.SQLException - if a database access error occurs or the result set is not updatable
Since:: 1.2
See Also:: What Is in the JDBC 2.0 API
