Method Detail

isAfterLast

public boolean isAfterLast()
                    throws java.sql.SQLException

JDBC 2.0

Determine if the cursor is after the last row in the result set.

Specified by:: isAfterLast in interface java.sql.ResultSet
Overrides:: isAfterLast in class ResultSet

isBeforeFirst

public boolean isBeforeFirst()
                      throws java.sql.SQLException

JDBC 2.0

Determine if the cursor is before the first row in the result set.

Specified by:: isBeforeFirst in interface java.sql.ResultSet
Overrides:: isBeforeFirst in class ResultSet

getConcurrency

public int getConcurrency()
                   throws java.sql.SQLException

JDBC 2.0 Return the concurrency of this result set. The concurrency used is determined by the statement that created the result set.

Specified by:: getConcurrency in interface java.sql.ResultSet
Overrides:: getConcurrency in class ResultSet

isFirst

public boolean isFirst()
                throws java.sql.SQLException

JDBC 2.0

Determine if the cursor is on the first row of the result set.

Specified by:: isFirst in interface java.sql.ResultSet
Overrides:: isFirst in class ResultSet

isLast

public boolean isLast()
               throws java.sql.SQLException

JDBC 2.0

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.

Specified by:: isLast in interface java.sql.ResultSet
Overrides:: isLast in class ResultSet

absolute

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

JDBC 2.0

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().

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

afterLast

public void afterLast()
               throws java.sql.SQLException

JDBC 2.0

Moves to the end of the result set, just after the last row. Has no effect if the result set contains no rows.

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

beforeFirst

public void beforeFirst()
                 throws java.sql.SQLException

JDBC 2.0

Moves to the front of the result set, just before the first row. Has no effect if the result set contains no rows.

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

cancelRowUpdates

public void cancelRowUpdates()
                      throws java.sql.SQLException

JDBC 2.0 The cancelRowUpdates() method may be called after calling an updateXXX() method(s) and before calling updateRow() to rollback the updates made to a row. If no updates have been made or updateRow() has already been called, then this method has no effect.

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

clearWarnings

public void clearWarnings()
                   throws java.sql.SQLException

After this call, getWarnings returns null until a new warning is reported for this ResultSet

Specified by:: clearWarnings in interface java.sql.ResultSet
Overrides:: clearWarnings in class ResultSet

close

public void close()
           throws java.sql.SQLException

In some cases, it is desirable to immediately release a ResultSet 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 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 java.sql.ResultSet
Overrides:: close in class ResultSet

deleteRow

public void deleteRow()
               throws java.sql.SQLException

JDBC 2.0 Delete the current row from the result set and the underlying database. Cannot be called when on the insert row.

Specified by:: deleteRow in interface java.sql.ResultSet
Overrides:: deleteRow in class ResultSet

first

public boolean first()
              throws java.sql.SQLException

JDBC 2.0

Moves to the first row in the result set.

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

insertRow

public void insertRow()
               throws java.sql.SQLException

JDBC 2.0 Insert the contents of the insert row into the result set and the database. Must be on the insert row when this method is called.

Specified by:: insertRow in interface java.sql.ResultSet
Overrides:: insertRow in class ResultSet

last

public boolean last()
             throws java.sql.SQLException

JDBC 2.0

Moves to the last row in the result set.

Specified by:: last in interface java.sql.ResultSet
Overrides:: last in class ResultSet

moveToCurrentRow

public void moveToCurrentRow()
                      throws java.sql.SQLException

JDBC 2.0 Move the cursor to the remembered cursor position, usually the current row. Has no effect unless the cursor is on the insert row.

Specified by:: moveToCurrentRow in interface java.sql.ResultSet
Overrides:: moveToCurrentRow in class ResultSet

moveToInsertRow

public void moveToInsertRow()
                     throws java.sql.SQLException

JDBC 2.0 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 java.sql.ResultSet
Overrides:: moveToInsertRow in class ResultSet

public boolean next()
             throws java.sql.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

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

public boolean prev()
             throws java.sql.SQLException

The prev method is not part of JDBC, but because of the architecture of this driver it is possible to move both forward and backward within the result set.

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

Overrides:: prev in class ResultSet

public boolean previous()
                 throws java.sql.SQLException

JDBC 2.0

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.

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

refreshRow

public void refreshRow()
                throws java.sql.SQLException

JDBC 2.0 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 java.sql.ResultSet
Overrides:: refreshRow in class ResultSet

relative

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

JDBC 2.0

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.

Specified by:: relative in interface java.sql.ResultSet
Overrides:: relative in class ResultSet

rowDeleted

public boolean rowDeleted()
                   throws java.sql.SQLException

JDBC 2.0 Determine if this row has been deleted. A deleted row may leave a visible "hole" in a result set. This method can be used to detect holes in a result set. The value returned depends on whether or not the result set can detect deletions.

Specified by:: rowDeleted in interface java.sql.ResultSet
Overrides:: rowDeleted in class ResultSet

rowInserted

public boolean rowInserted()
                    throws java.sql.SQLException

JDBC 2.0 Determine if the current row has been inserted. The value returned depends on whether or not the result set can detect visible inserts.

Specified by:: rowInserted in interface java.sql.ResultSet
Overrides:: rowInserted in class ResultSet

rowUpdated

public boolean rowUpdated()
                   throws java.sql.SQLException

JDBC 2.0 Determine if the current row has been updated. The value returned depends on whether or not the result set can detect updates.

Specified by:: rowUpdated in interface java.sql.ResultSet
Overrides:: rowUpdated in class ResultSet

updateAsciiStream

public void updateAsciiStream(int columnIndex,
                              java.io.InputStream x,
                              int length)
                       throws java.sql.SQLException

JDBC 2.0 Update a column with an ascii stream value. The updateXXX() methods are used to update column values in the current row, or the insert row. The updateXXX() methods do not update the underlying database, instead the updateRow() or insertRow() methods are called to update the database.

Specified by:: updateAsciiStream in interface java.sql.ResultSet
Overrides:: updateAsciiStream in class ResultSet

updateAsciiStream

public void updateAsciiStream(java.lang.String columnName,
                              java.io.InputStream x,
                              int length)
                       throws java.sql.SQLException

Specified by:: updateAsciiStream in interface java.sql.ResultSet
Overrides:: updateAsciiStream in class ResultSet

updateBigDecimal

public void updateBigDecimal(int columnIndex,
                             java.math.BigDecimal x)
                      throws java.sql.SQLException

JDBC 2.0 Update a column with a BigDecimal value. The updateXXX() methods are used to update column values in the current row, or the insert row. The updateXXX() methods do not update the underlying database, instead the updateRow() or insertRow() methods are called to update the database.

Specified by:: updateBigDecimal in interface java.sql.ResultSet
Overrides:: updateBigDecimal in class ResultSet

updateBigDecimal

public void updateBigDecimal(java.lang.String columnName,
                             java.math.BigDecimal x)
                      throws java.sql.SQLException

Specified by:: updateBigDecimal in interface java.sql.ResultSet
Overrides:: updateBigDecimal in class ResultSet

updateBinaryStream

public void updateBinaryStream(int columnIndex,
