-
-
Method Detail
-

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 interfacejava.sql.ResultSet

close
public void close() throws java.sql.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 interfacejava.lang.AutoCloseable

- Specified by:
absolute
in interfacejava.sql.ResultSet

- Throws:
java.sql.SQLException
- if a database-access error occurs, or row is 0, or result set type is TYPE_FORWARD_ONLY.

JDBC 2.0Moves 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 interfacejava.sql.ResultSet
- Returns:
- true if on a row, false otherwise.
- Throws:
java.sql.SQLException
- if a database-access error occurs, or there is no current row, or result set type is TYPE_FORWARD_ONLY.
-
previous
public boolean previous() throws java.sql.SQLException

- Specified by:
previous
in interfacejava.sql.ResultSet
- Returns:
- true if on a valid row, false if off the result set.
- Throws:
java.sql.SQLException

The default value is set by the statement that creates the result set. The fetch size may be changed at any time.- Specified by:
setFetchSize
in interfacejava.sql.ResultSet

rows
- the number of rows to fetch- Throws:
java.sql.SQLException

If the language resultset is updatable, then JDBC ResultSet object will also have the CONCUR_UPDATABLE concurrency. If lanugage resultset is not updatable, then JDBC ResultSet object concurrency will be set to CONCUR_READ_ONLY.- Specified by:

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.

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:

-
setDynamicResultSet
void setDynamicResultSet(EmbedStatement owningStmt)
A dynamic result was created in a procedure by a nested connection. Once the procedure returns, there is a good chance that connection is closed, so we re-attach the result set to the connection of the statement the called the procedure, which will be still open.
In the case where the dynamic result will not be accessible then owningStmt will be null, the ResultSet will be linked to the root connection to allow its close method to work. It will remain attached to its original statement.
