Drawing UPCA In Java

The cursor will then be associated with the collection of Properties related to the specified asset:
Set @CrsrVar = Cursor For Select Property, Value, Unit From InventoryProperty inner join Property On InventoryProperty.PropertyId = Property.PropertyId Where InventoryProperty.InventoryId = @intInventoryId
Before it can be used, the cursor needs to be opened:
Open @CrsrVar
The content of the first record can then be fetched into local variables:
Fetch Next From @CrsrVar Into @chvProperty, @chvValue, @chvUnit
If the fetch was successful, we can start a loop to process the complete recordset:
While (@@FETCH_STATUS = 0)
After the values from the first record are processed, we read the next record:
Fetch Next From @CrsrVar Into @chvProperty, @chvValue, @chvUnit
Once all records have been read, the value of @@fetch_status is set to 1 and we exit the loop. We need to close and deallocate the cursor and finish the stored procedure.
Close @CrsrVar Deallocate @CrsrVar
Now, let s save and execute this stored procedure:
Declare @chvRes varchar(8000) Exec prGetInventoryProperties_Cursor 5, @chvRes OUTPUT Select @chvRes Properties

Cursor-Related Statements and Functions
Let s review statements and functions that you need to utilize to control cursors.
The Declare Cursor Statement
This statement declares the Transact-SQL cursor and specifies its behavior and the query on which it is built. It is possible to use syntax based on the SQL-92 standard or native Transact-SQL syntax. We will display only the simplified syntax. If you need more details, refer to SQL Server Books Online.
Declare cursor_name Cursor For select_statement
The name of the cursor is an identifier that complies with the rules set for local variables.
The Open Statement
The Open statement executes the Select statement specified in the Declare Cursor statement and populates the cursor:
Open { { [Global] cursor_name } | cursor_variable_name}
The Fetch Statement
The Fetch statement reads the row specified in the Transact-SQL cursor.
Fetch [ [ Next | Prior | First | Last | Absolute {n | @nvar}
4:

| Relative {n | @nvar} ] From ] { { [Global] cursor_name } | @cursor_variable_name} [Into @variable_name[,...n] ]
This statement can force the cursor to position the current record at the Next, Prior, First, or Last record. It is also possible to specify the Absolute position of the record or a position Relative to the current record. If the developer specifies a list of global variables in the Into clause, those variables will be filled with values from the specified record. If the cursor has just been opened, you can use Fetch Next to read the first record.
@@fetch_status
@@fetch_status is a function (or global variable) that returns the success code of the last Fetch statement executed during the current connection. It is often used as an exit criterion in loops that fetch records from a cursor.
