getColumnType
Check the column is in range *and* return the JDBC type of the column.- Throws:
SQLException
- ResultSet is not on a row or columnIndex is out of range.
-
next
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 interfaceResultSet
- Returns:
- true if the new current row is valid; false if there are no more rows
- Throws:
SQLException
- thrown on failure.

close
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 interfaceAutoCloseable
- Specified by:
close
in interfaceResultSet
- Throws:
SQLException
- thrown on failure.
-
markClosed
private void markClosed()Mark this ResultSet as closed and trigger the closing of the Statement if necessary. -
wasNull
A column may have the value of SQL NULL; wasNull reports whether the last column read had this special value. Note that you must first call getXXX on a column to try to read its value and then call wasNull() to find if the value was the SQL NULL.we take the least exception approach and simply return false if no column has been read yet.
- Specified by:
wasNull
in interfaceResultSet
- Returns:
- true if last column read was SQL NULL
- Throws:
SQLException
- Thrown if this ResultSet is closed

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 interfaceResultSet

- true if on the result set, false if off.
- Throws:
SQLException
- if a database-access error occurs, or row is 0, or result set type is TYPE_FORWARD_ONLY.

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 interfaceResultSet
- Returns:
- true if on a row, false otherwise.
- Throws:
SQLException
- if a database-access error occurs, or there is no current row, or result set type is TYPE_FORWARD_ONLY.
-

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 interfaceResultSet
- Returns:
- true if on a valid row, false if off the result set.
- Throws:
SQLException
- if a database-access error occurs, or result set type is TYPE_FORWAR_DONLY.

getConcurrency
JDBC 2.0 Return the concurrency of this result set. The concurrency is determined as follows If Statement object has CONCUR_READ_ONLY concurrency, then ResultSet object will also have the CONCUR_READ_ONLY concurrency. But if Statement object has CONCUR_UPDATABLE concurrency, then the concurrency of ResultSet object depends on whether the underlying language resultset is updatable or not. 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:

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.

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 interfaceResultSet
- Throws:
SQLException

An exception on many method calls to JDBC objects does not change the state of the transaction or statement, or even the underlying object. This method simply wraps the excecption in a SQLException. Examples are:- getXXX() calls on ResultSet - ResultSet is not closed.
- setXXX() calls on PreparedStatement - ResultSet is not closed.
-
setDynamicResultSet
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. -

- Specified by:
compareTo
in interfaceComparable
-
checkScrollCursor
Checks if the result set has a scrollable cursor.- Parameters:
methodName
- name of the method which requests the check- Throws:

-
getMaxColumnWidth
private final int getMaxColumnWidth(int columnIndex) Return the user-defined maximum size of the column. Note that this may be different from the maximum column size Derby is able, or allowed, to handle (called 'maximum maximum length').- Parameters:
columnIndex
- the 1-based index of the column- Returns:
- the maximum length of the column

dataTypeConversion
-
useStreamOrLOB
Mark a column as already having a stream or LOB accessed from it. If the column was already accessed, throw an exception.- Parameters:
columnIndex
- 1-based column index- Throws:
SQLException
- if the column has already been accessed
-
checkLOBMultiCall
Checks if a stream or a LOB object has already been created for the specified LOB column.Accessing a LOB column more than once is not forbidden by the JDBC specification, but the Java API states that 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. The restriction was implemented in Derby due to complexities with the positioning of store streams when the user was given multiple handles to the stream.
- Parameters:
columnIndex
- 1-based index of the LOB column- Throws:
SQLException
- if the column has already been accessed
-
