The Execute Method
The Execute method executes the query, SQL statement or procedure specified in the
CommandText property of the Command object.
The results are stored in a new Recordset object if it is a row-returning
query. A closed Recordset object will be returned if it is not a row-returning
query.
Syntax for row-returning
Set rs=objcommand.Execute(ra,parameters,options)
|
Syntax for non-row-returning
objcommand.Execute ra,parameters,options
|
| Parameter |
Description |
| ra |
Optional. Returns the number of records affected by a
query. For a row-returning query, use the RecordCount property of the Recordset object to
count of how many records are in the object. |
| parameters |
Optional. Parameter values passed with an SQL
statement. Used to change, update, or insert new parameter values into the Parameters Collection.
|
| options |
Optional. Sets how the provider should evaluate the CommandText property.
Can be one or more CommandTypeEnum or ExecuteOptionEnum values.
Default is adCmdUnspecified.
|
Example
<%
Set objcommand.Text="SELECT * FROM Customers"
objCommand.Execute
%>
or
<%
Set objcommand.Text="Customers"
objCommand.Execute(,,adCmdTableDirect)
%>
|
CommandTypeEnum Values
| Constant |
Value |
Description |
| adCmdUnspecified |
-1 |
Does not specify the command type argument. |
| adCmdText |
1 |
Evaluates CommandText as a textual definition of a command or stored
procedure call. |
| adCmdTable |
2 |
Evaluates CommandText as a table name whose columns are all returned
by an internally generated SQL query. |
| adCmdStoredProc |
4 |
Evaluates CommandText as a stored procedure name. |
| adCmdUnknown |
8 |
Indicates that the type of command in the CommandText
property is not known. |
| adCmdFile |
256 |
Evaluates CommandText as the file name of a persistently stored
Recordset. Used with Recordset.Open or Requery only. |
| adCmdTableDirect |
512 |
Evaluates CommandText as a table name whose columns are all returned.
Used with Recordset.Open or Requery only. To use the Seek method, the
Recordset must be opened with adCmdTableDirect. This value cannot be
combined with the ExecuteOptionEnum value adAsyncExecute. |
ExecuteOptionEnum Values
| Constant |
Value |
Description |
| adOptionUnspecified |
-1 |
Indicates that the command is unspecified. |
| adAsyncExecute |
16 |
Indicates that the command should execute asynchronously. This value
cannot be combined with the CommandTypeEnum value adCmdTableDirect. |
| adAsyncFetch |
32 |
Indicates that the remaining rows after the initial quantity specified
in the CacheSize property should be retrieved asynchronously. |
| adAsyncFetchNonBlocking |
64 |
Indicates that the main thread never blocks while retrieving. If the
requested row has not been retrieved, the current row automatically
moves to the end of the file. If you open a Recordset from a Stream
containing a persistently stored Recordset, adAsyncFetchNonBlocking will
not have an effect; the operation will be synchronous and blocking.
adAsynchFetchNonBlocking has no effect when the adCmdTableDirect option
is used to open the Recordset. |
| adExecuteNoRecords |
128 |
Indicates that the command text is a command or stored procedure that
does not return rows (for example, a command that only inserts data). If
any rows are retrieved, they are discarded and not returned.
adExecuteNoRecords can only be passed as an optional parameter to the
Command or Connection Execute method. |
| adExecuteStream |
256 |
Indicates that the results of a command execution should be returned
as a stream. adExecuteStream can only be passed as an optional parameter
to the Command Execute method. |
| adExecuteRecord |
512 |
Indicates that the CommandText is a command or stored procedure that
returns a single row which should be returned as a Record object. |
