Calling moveToFirst does two things: it allows you to test whether the query returned an empty set by testing the return value and it moves the cursor to the first result when the set is not empty. Note that to guard against an empty return set, the code you posted should be testing the return value which it is not doing. Unlike the call to moveToFirstthe test for if c! It will never return null. Cursor is not a Row of the result of query. Cursor is an object that can iterate on the result rows of your query.

Cursor can moves to each row.

Active Oldest Votes. These applications need a mechanism to work with one row or a small block of rows at a time. Cursors are an extension to result sets that provide that mechanism.

Supporting different levels of visibility to changes made by other users to the database data that is presented in the result set.

think, that

The JDBC specification provides support for forward-only and scrollable cursors that are sensitive or insensitive to changes made by other jobs, and can be read-only or atable. The absolute method can be approximated by a combination of calls to the first and relative methods for dynamic cursors.

are right

The getRow method with all forward-only cursor types returns the number of rows read so far through the cursor. When an application makes an unsupported cursor positioning call, or an unsupported call to the getRow method, an exception is thrown with the message, "The requested operation is not supported with this cursor type.

If the cursor is positioned on a deleted row, column values are unavailable, and the rowDeleted method returns "true". Deleted rows cannot be ated. Forward and dynamic cursors expose deleted rows in a similar way, but only while the cursors remain accessible in the fetch buffer. For forward cursors, this is fairly straightforward.

sounds tempting

For dynamic cursors it more complex when the fetch size is greater than 1. An application can move the cursor forward and backward within the window that is defined by the fetch buffer, but the deleted row will disappear when the original fetch buffer in which it was ated is left.

If an application does not want to see transient deleted rows by using dynamic cursors, a fetch relative 0 should be used.

remarkable, rather

If the row was ated outside the cursor, a deleted row will appear at the row's original position, but the row will appear in the cursor only if another row with the new key values was present in the cursor, but has since been deleted.

For dynamic cursors, ated rows will retain their position within the fetch buffer until the window that is defined by the fetch buffer is left. ated rows might subsequently reappear at different positions within the result set, or might disappear completely.

not absolutely that

SQL Server can sometimes choose to implement a cursor type other than the one requested, which is referred to as an implicit cursor conversion or cursor degradation. With SQL Server 8.

talk this

This exception occurs because the SQL Server 8. In-place ates are supported for cursors where the cursor type and concurrency support ates.

In situations where the row is not atable, such as because of an optimistic concurrency conflict such as a competing ate or deletion, the exception might not arise until insertRowateRowor deleteRow is called. This avoids problems where a column is ated by using a different type from the type returned by the server, and subsequent getter calls could invoke client side type conversions that give inaccurate results.

If the ateRow method is called when no columns have been ated, the JDBC driver will throw an exception with the message, "ateRow called when no columns have been ated. The moveToInsertRow method effectively places the result set into insert mode, and cursor positioning methods terminate insert mode.

Custom Cursor for Chrome™ - Change your regular mouse pointer to a fun, custom cursor!

Relative cursor positioning calls move the cursor relative to the position it was at before moveToInsertRow was called. After cursor positioning calls, the eventual destination cursor position becomes the new cursor position.

very valuable

If the cursor positioning call made while in insert mode does not succeed, the cursor position after the failed call is the original cursor position before moveToInsetRow was called. If insertRow fails, the cursor remains on the insert row and the cursor remains in insert mode.

Dating cursor

Columns in the insert row are initially in an uninitialized state. A call to the insertRow method returns all the columns in the insert row to an uninitialized state.

final, sorry
