Must have Field Length

Posted on 2001-07-23

I have the following function returning a newtable "Table1" with definitions from another table "GIS".
The new table contains the table definitions but I don't know the "FieldLength" of the table requested.
Is there any way to revise this code to include the
"Field Length" of the table that i'am requuesting information from.


******* Start of Code
Dim d as database
Set d = CurrentDB

Dim r as recordset
Dim f as Field
Dim t as tabledef
Set t = d.CreateTableDef("setup") 'definition table setup
' definition setup in new table
Set f = t.CreateField("FieldName", dbText, 50)
t.Fields.Append f
Set f = t.CreateField("FieldType", dbText, 15)
t.Fields.Append f
Set f = t.CreateField("Comments", dbText, 150)
t.Fields.Append f
d.TableDefs.Append t
Set t = Nothing

Set r = d.OpenRecordset("Table1") 'NameOfDestTblHere

set t = d.Tabledefs("GIS") ' Requested information from this table

For each f in t.Fields
 r.AddNew
 r![FieldName] = f.Name
 r![FieldType] = fType(f.Type)
 r![Comments] = f.Properties("Description").Value
 r.Update
Next f
r.Close
Set f = Nothing
Set t = Nothing
Set d = Nothing
******* End of code


Public Function fType(ByVal f As Long) As String

   Select Case f                                               'Value
       Case dbBoolean:     fType = "Boolean"                   '   1
       Case dbByte:        fType = "Byte"                      '   2
       Case dbInteger:     fType = "Integer"                   '   3
       Case dbLong:        fType = "Long"                      '   4
       Case dbCurrency:    fType = "Currency"                  '   5
       Case dbSingle:      fType = "Single"                    '   6
       Case dbDouble:      fType = "Double"                    '   7
       Case dbDate:        fType = "Date/Time"                 '   8
       Case dbBinary:      fType = "Binary"                    '   9
       Case dbText:        fType = "Text"                      '  10
       Case dbLongBinary:  fType = "Long Binary (OLE Object)"  '  11
       Case dbMemo:        fType = "Memo"                      '  12
       Case dbGUID:        fType = "GUID"                      '  15
       Case dbBigInt:      fType = "Big Integer"               '  16
       Case dbVarBinary:   fType = "VarBinary"                 '  17
       Case dbChar:        fType = "char"                      '  18
       Case dbNumeric:     fType = "Numeric"                   '  19
       Case dbDecimal:     fType = "Decimal"                   '  20
       Case dbFloat:       fType = "Float"                     '  21
       Case dbTime:        fType = "Time"                      '  22
       Case dbTimeStamp:   fType = "Time Stamp"                '  23
       Case Else:          fType = "(Unknown)"
   End Select

End Function

What's the end goal here?  To calculate storage requirements?  Not quite sure what your asking for/looking to do.

j,
Looking to create a  new table with field definitions, (of another table)
instead of having to go into "Design View" of a table and find all the information about a specific table.
This new table will be constructed  as the code suggests.
However, it does not go out and look at the "field length"
of text fields.

Hope this helps
Dave

You want to include the Size property of the field object:

r![Comments] = f.Properties("Description").Value & " Size: " & f.Size
