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)
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.
