GetRows
This example demonstrates how to use the GetRows method.
The ADO Recordset object is used to hold a set of records from a database table. A Recordset object consist of records and columns (fields).
In ADO, this object is the most important and the one used most often to manipulate data from a database.
set objRecordset=Server.CreateObject("ADODB.recordset")
|
Recordset objects can support two types of updating:
In ADO there are 4 different cursor types defined:
The cursor type can be set by the CursorType property or by the CursorType parameter in the Open method.
Note: Not all providers support all methods or properties of the Recordset object.
| Property | Description |
|---|---|
| AbsolutePage | Sets or returns a value that specifies the page number in the Recordset object |
| AbsolutePosition | Sets or returns a value that specifies the ordinal position of the current record in the Recordset object |
| ActiveCommand | Returns the Command object associated with the Recordset |
| ActiveConnection | Sets or returns a definition for a connection if the connection is closed, or the current Connection object if the connection is open |
| BOF | Returns true if the current record position is before the first record, otherwise false |
| Bookmark | Sets or returns a bookmark. The bookmark saves the position of the current record |
| CacheSize | Sets or returns the number of records that can be cached |
| CursorLocation | Sets or returns the location of the cursor service |
| CursorType | Sets or returns the cursor type of a Recordset object |
| DataMember | Sets or returns the name of the data member that will be retrieved from the object referenced by the DataSource property |
| DataSource | Specifies an object containing data to be represented as a Recordset object |
| EditMode | Returns the editing status of the current record |
| EOF | Returns true if the current record position is after the last record, otherwise false |
| Filter | Sets or returns a filter for the data in a Recordset object |
| Index | Sets or returns the name of the current index for a Recordset object |
| LockType | Sets or returns a value that specifies the type of locking when editing a record in a Recordset |
| MarshalOptions | Sets or returns a value that specifies which records are to be returned to the server |
| MaxRecords | Sets or returns the maximum number of records to return to a Recordset object from a query |
| PageCount | Returns the number of pages with data in a Recordset object |
| PageSize | Sets or returns the maximum number of records allowed on a single page of a Recordset object |
| RecordCount | Returns the number of records in a Recordset object |
| Sort | Sets or returns the field names in the Recordset to sort on |
| Source | Sets a string value or a Command object reference, or returns a String value that indicates the data source of the Recordset object |
| State | Returns a value that describes if the Recordset object is open, closed, connecting, executing or retrieving data |
| Status | Returns the status of the current record with regard to batch updates or other bulk operations |
| StayInSync | Sets or returns whether the reference to the child records will change when the parent record position changes |
| Method | Description |
|---|---|
| AddNew | Creates a new record |
| Cancel | Cancels an execution |
| CancelBatch | Cancels a batch update |
| CancelUpdate | Cancels changes made to a record of a Recordset object |
| Clone | Creates a duplicate of an existing Recordset |
| Close | Closes a Recordset |
| CompareBookmarks | Compares two bookmarks |
| Delete | Deletes a record or a group of records |
| Find | Searches for a record in a Recordset that satisfies a specified criteria |
| GetRows | Copies multiple records from a Recordset object into a two-dimensional array |
| GetString | Returns a Recordset as a string |
| Move | Moves the record pointer in a Recordset object |
| MoveFirst | Moves the record pointer to the first record |
| MoveLast | Moves the record pointer to the last record |
| MoveNext | Moves the record pointer to the next record |
| MovePrevious | Moves the record pointer to the previous record |
| NextRecordset | Clears the current Recordset object and returns the next Recordset object by looping through a series of commands |
| Open | Opens a database element that gives you access to records in a table, the results of a query, or to a saved Recordset |
| Requery | Updates the data in a Recordset by re-executing the query that made the original Recordset |
| Resync | Refreshes the data in the current Recordset from the original database |
| Save | Saves a Recordset object to a file or a Stream object |
| Seek | Searches the index of a Recordset to find a record that matches the specified values |
| Supports | Returns a boolean value that defines whether or not a Recordset object supports a specific type of functionality |
| Update | Saves all changes made to a single record in a Recordset object |
| UpdateBatch | Saves all changes in a Recordset to the database. Used when working in batch update mode |
Note: You cannot handle events using VBScript or JScript (only Visual Basic, Visual C++, and Visual J++ languages can handle events).
| Event | Description |
|---|---|
| EndOfRecordset | Triggered when you try to move to a record after the last record |
| FetchComplete | Triggered after all records in an asynchronous operation have been fetched |
| FetchProgress | Triggered periodically in an asynchronous operation, to state how many more records that have been fetched |
| FieldChangeComplete | Triggered after the value of a Field object change |
| MoveComplete | Triggered after the current position in the Recordset has changed |
| RecordChangeComplete | Triggered after a record has changed |
| RecordsetChangeComplete | Triggered after the Recordset has changed |
| WillChangeField | Triggered before the value of a Field object change |
| WillChangeRecord | Triggered before a record change |
| WillChangeRecordset | Triggered before a Recordset change |
| WillMove | Triggered before the current position in the Recordset changes |
| Collection | Description |
|---|---|
| Fields | Indicates the number of Field objects in the Recordset object |
| Properties | Contains all the Property objects in the Recordset object |
| Property | Description |
|---|---|
| Count | Returns the number of items in the fields collection. Starts
at zero.
Example: countfields = rs.Fields.Count |
| Item(named_item/number) | Returns a specified item in the fields collection.
Example: itemfields = rs.Fields.Item(1) |
| Property | Description |
|---|---|
| Count | Returns the number of items in the properties collection. Starts
at zero.
Example: countprop = rs.Properties.Count |
| Item(named_item/number) | Returns a specified item in the properties collection.
