RecordCount Property

Applies To

OraDynaset Object

OraSQLStmt Object

Description

Not available at design time and read-only at run time.

Usage

record_count = oradynaset.RecordCountrecord_count = orasqlstmt.RecordCount

Data Type

Long Integer

Remarks

Referencing this property requires that the entire result table be fetched immediately from an Oracle database to determine the count of records. Due to the potentially severe performance impact of this, the user should avoid using this property and instead execute an additional query using the COUNT(*) clause, and use the SnapshotID property to guarantee time consistency. For an example, see the SnapShot property.

Referencing this property while using the ORADYN_NOCACHE option of the CreateDynaset method causes an implicit MoveLast operation and makes the current record the last record in the dynaset.

Examples

RecordCount Example (OraDynaset)

This example demonstrates the use of the RecordCount property to determine the number of records retrieved with a SELECT statement and OraDynaset. Copy and paste this code into the definition section of a form. Then, press F5.

Sub Form_Load ()
 
 'Declare variables as OLE Objects.
 Dim OraSession As OraSession 
 Dim OraDatabase As OraDatabase 
 Dim OraDynaset As OraDynaset 
 
 'Create the OraSession Object.
 Set OraSession = CreateObject("OracleInProcServer.XOraSession")
 
 'Create the OraDatabase Object by opening a connection to Oracle.
 Set OraDatabase = OraSession.OpenDatabase("ExampleDb", "scott/tiger", 0&)
 
 'Create the dynaset.
 Set OraDynaset = OraDatabase.CreateDynaset("select * from emp", 0&)
 
 'Display the number of records. Note that this causes
 'all records to be fetched to ensure an accurate count.
 
 MsgBox OraDynaset.RecordCount & " records retrieved."
 
 
End Sub

Record Count Example (OraSQLStmt)

The following example shows the number of records inserted into the database after using an INSERT statement with OraSQLStmt.

Dim OraSession As OraSession 
Dim OraDatabase As OraDatabase 
Dim OraDynaset As OraDynaset 
Dim OraSqlStmt As OraSQLStmt 
Dim OraPArray1 As OraParamArray 
Dim OraPArray2 As OraParamArray
Dim I As Integer  
  
On Error GoTo ERR_array_sql 
  
'Test case for inserting/updating/deleting multiple rows using parameter arrays 
'with SQL statements  
Set OraSession = CreateObject("OracleInProcServer.XOraSession") 
Set OraDatabase = OraSession.OpenDatabase("exampledb", "scott/tiger", 0&) 
 
'Create table  
OraDatabase.ExecuteSQL ("create table part_nos(partno number, description" & _ 
                  "char(50), primary key(partno))")  
 
OraDatabase.Parameters.AddTable "PARTNO", ORAPARM_INPUT, ORATYPE_NUMBER, 10, 22 
OraDatabase.Parameters.AddTable "DESCRIPTION", ORAPARM_INPUT, ORATYPE_CHAR, _ 
              10, 50 
If OraDatabase.LastServerErr <> 0 Or OraDatabase.LastServerErrText <> "" Then
  MsgBox "Error" 
End If  
 
Set OraPArray1 = OraDatabase.Parameters("PARTNO") 
Set OraPArray2 = OraDatabase.Parameters("DESCRIPTION") 
 
'Initialize arrays 
For I = 0 To 9 
  achar = "Description" + Str(I) 
  OraPArray1.put_Value 1000 + I, I 
  OraPArray2.put_Value achar, I 
Next I  
 
Set OraSqlStmt = OraDatabase.CreateSql("insert into" & _  
          "part_nos(partno, description) values(:PARTNO,:DESCRIPTION)", 0&) 
If OraDatabase.LastServerErr <> 0 Or OraDatabase.LastServerErrText <> "" Then  
    MsgBox "Error" 
End If 
MsgBox "# of records inserted : " & OraSqlStmt.RecordCount 
  
Exit Sub
