NumericScale and Precision Properties Example (VB)

This example uses the NumericScale and Precision properties to display the numeric scale and precision of fields in the Discounts table of the Pubs database.

'BeginNumericScaleVB

    'To integrate this code
    'replace the data source and initial catalog values
    'in the connection string

Public Sub NumericScaleX()

    ' connection and recordset variables
   Dim rstDiscounts As ADODB.Recordset
   Dim Cnxn As ADODB.Connection
   Dim fldTemp As ADODB.Field

   Dim strSQLDiscounts As String

   ' Open connection
   Set Cnxn = New ADODB.Connection
   strCnxn = "Provider='sqloledb';Data Source='MySqlServer';Initial Catalog='Pubs';Integrated Security='SSPI';"

   Cnxn.Open strCnxn
   
   ' Open recordset
   Set rstDiscounts = New ADODB.Recordset
   strSQLDiscounts = "Discounts"
   rstDiscounts.Open strSQLDiscounts, Cnxn, adOpenStatic, adLockReadOnly, adCmdTable

   ' Display numeric scale and precision of
   ' numeric and small integer fields
   For Each fldTemp In rstDiscounts.Fields
      If fldTemp.Type = adNumeric Or fldTemp.Type = adSmallInt Then

   Next fldTemp

    ' clean up
   rstDiscounts.Close
