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, you can
iterate through it only once and only from the first row to the
last row. It is 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
getter methods (getBoolean, getLong, and so on)
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 getter methods, a JDBC driver attempts
to convert the underlying data to the Java type specified in the
getter method and returns a suitable Java value. The JDBC specification
has a table showing the allowable mappings from SQL types to Java types
that can be used by the ResultSet getter methods.
Column names used as input to getter methods are case insensitive. When a getter 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, the programmer should take care to guarantee that they uniquely refer to the intended columns, which can be assured with the SQL AS clause.
A set of updater methods were added to this interface in the JDBC 2.0 API (Java 2 SDK, Standard Edition, version 1.2). The comments regarding parameters to the getter methods also apply to parameters to the updater methods.
The updater 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 column 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 ResultSetMetaData
object returned by the ResultSet.getMetaData method.

Method Details
-
next
Moves the cursor forward one row from its current position. AResultSetcursor is initially positioned before the first row; the first call to the methodnextmakes the first row the current row; the second call makes the second row the current row, and so on.When a call to the
nextmethod returnsfalse, the cursor is positioned after the last row. Any invocation of aResultSetmethod which requires a current row will result in aSQLExceptionbeing thrown. If the result set type isTYPE_FORWARD_ONLY, it is vendor specified whether their JDBC driver implementation will returnfalseor throw anSQLExceptionon a subsequent call tonext.If an input stream is open for the current row, a call to the method
nextwill implicitly close it. AResultSetobject's warning chain is cleared when a new row is read.- Returns:
trueif the new current row is valid;falseif there are no more rows- Throws:
SQLException- if a database access error occurs or this method is called on a closed result set
-
close
Releases thisResultSetobject's database and JDBC resources immediately instead of waiting for this to happen when it is automatically closed.The closing of a
ResultSetobject does not close theBlob,CloborNClobobjects created by theResultSet.Blob,CloborNClobobjects remain valid for at least the duration of the transaction in which they are created, unless theirfreemethod is invoked.When a
ResultSetis closed, anyResultSetMetaDatainstances that were created by calling thegetMetaDatamethod remain accessible.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.Calling the method
closeon aResultSetobject that is already closed is a no-op.- Specified by:
closein interfaceAutoCloseable- Throws:
SQLException- if a database access error occurs
-
wasNull
Reports whether the last column read had a value of SQLNULL. Note that you must first call one of the getter methods on a column to try to read its value and then call the methodwasNullto see if the value read was SQLNULL.- Returns:
trueif the last column value read was SQLNULLandfalseotherwise- Throws:
SQLException- if a database access error occurs or this method is called on a closed result set
-
getString
Retrieves the value of the designated column in the current row of thisResultSetobject as aStringin the Java programming language.- Parameters:
columnIndex- the first column is 1, the second is 2, ...- Returns:
- the column value; if the value is SQL
NULL, the value returned isnull - Throws:
SQLException- if the columnIndex is not valid; if a database access error occurs or this method is called on a closed result set
-
getBoolean
Retrieves the value of the designated column in the current row of thisResultSetobject as abooleanin the Java programming language.If the designated column has a datatype of CHAR or VARCHAR and contains a "0" or has a datatype of BIT, TINYINT, SMALLINT, INTEGER or BIGINT and contains a 0, a value of
falseis returned. If the designated column has a datatype of CHAR or VARCHAR and contains a "1" or has a datatype of BIT, TINYINT, SMALLINT, INTEGER or BIGINT and contains a 1, a value oftrueis returned.- Parameters:
columnIndex- the first column is 1, the second is 2, ...- Returns:
- the column value; if the value is SQL
NULL, the value returned isfalse - Throws:
SQLException- if the columnIndex is not valid; if a database access error occurs or this method is called on a closed result set
-
getByte
Retrieves the value of the designated column in the current row of thisResultSetobject as abytein the Java programming language.- Parameters:
columnIndex- the first column is 1, the second is 2, ...- Returns:

getCursorName
Retrieves 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 formSELECT FOR UPDATE. IfFOR UPDATEis 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.- Returns:

If the value is an SQL
NULL, the driver returns a Javanull.This method may also be used to read database-specific abstract data types. In the JDBC 2.0 API, the behavior of method
getObjectis extended to materialize data of SQL user-defined types.If
Connection.getTypeMapdoes not throw aSQLFeatureNotSupportedException, then 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()).

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 an updater method, but before calling the methodupdateRow, then the updates made to the row are lost. Calling the methodrefreshRowfrequently will likely slow performance.- Throws:
SQLException- if a database access error occurs; this method is called on a closed result set; the result set type isTYPE_FORWARD_ONLYor if this method is called when the cursor is on the insert rowSQLFeatureNotSupportedException- if the JDBC driver does not support this method or this method is not supported for the specified result set type and result set concurrency.- Since:
- 1.2
-
cancelRowUpdates
Cancels the updates made to the current row in thisResultSetobject. This method may be called after calling an updater method(s) and before calling the methodupdateRowto roll back the updates made to a row. If no updates have been made orupdateRowhas already been called, this method has no effect.- Throws:
SQLException- if a database access error occurs; this method is called on a closed result set; the result set concurrency isCONCUR_READ_ONLYor if this method is called when the cursor is on the insert rowSQLFeatureNotSupportedException- if the JDBC driver does not support this method- Since:
- 1.2
-
moveToInsertRow
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 updater methods prior to inserting the row into the result set. Only the updater, getter, 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. An updater method must be called before a getter method can be called on a column value.- Throws:
SQLException- if a database access error occurs; this method is called on a closed result set or the result set concurrency isCONCUR_READ_ONLYSQLFeatureNotSupportedException- if the JDBC driver does not support this method- Since:
- 1.2
-
