ADO Connection object >>Execute Method
It executes the specified query, SQL statement, stored procedure, or
provider-specific text.
Syntax

Set recordset = connection.Execute (CommandText, RecordsAffected, Options)
|
Example
Dim cnn As ADODB.Connection
Dim rst As ADODB.Recordset
Set cnn = New ADODB.Connection
Set rst = New ADODB.Recordset
cnn.Open " Provider=Microsoft.Jet.OLEDB.4.0;"
& _
"Data Source=D:\MyData\Northwind.mdb;" & _
"User Id=91128; Password=planning;"
Set rst = cnn.Execute("Select * from Employees")
Do Until rst.EOF
Debug.Print rst.Fields(0).Value
rst.MoveNext
Loop
cnn.Close

Parameter |
Description |
CommandText |
A String value that contains the SQL statement, stored
procedure, a URL, or provider-specific text to execute. Optionally,
table names can be used but only if the provider is SQL aware. For
example if a table name of "Customers" is used, ADO will automatically
prepend the standard SQL Select syntax to form and pass "SELECT * FROM
Customers" as a Transact-SQL statement to the provider. |
RecordsAffected |
Optional. A Long variable to which the provider
returns the number of records that the operation affected. |
Options |
Optional. A Long value that indicates how the
provider should evaluate the CommandText argument. Can be a bitmask of
one or more CommandTypeEnum or ExecuteOptionEnum values.
Note:
Do not use adExecuteStream with the Execute method of a
Connection object. |
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 |
|
Indicates that the command should execute asynchronously. This value
cannot be combined with the CommandTypeEnum value adCmdTableDirect. |
adAsyncFetch |
|
Indicates that the remaining rows after the initial quantity
specified in the CacheSize property should be retrieved asynchronously. |
adAsyncFetchNonBlocking |
|
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 |
|
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 |
|
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 |
|
Indicates that the CommandText is a command or stored procedure that
returns a single row which should be returned as a Record object. |
