Read the Descriptions from all columns in MS Access database

From one of my developers. This VBA (couldn’t find an approach in .Net) will loop through all the tables and write out the description from all the fields.

 

TODO’s include grabbing descriptions for tables and then tweaking below to create ALTER statements so that the comments can be applied to a server RDBMS after migration from Access (since almost none of the migration utilities I’ve seen migrate this documentation from Access).

 

Option Explicit

[cc lang=’vb’ ]’call readAllTables
Public Function readAllTables()

Dim DB As Database, tbl As TableDef, fld As DAO.Field

Dim RS As Recordset
Dim Table As String
Dim allDesc As String

Set DB = CurrentDb()

For Each tbl In DB.TableDefs
If Left$(tbl.Name, 4) <> “MSys” Then
‘Debug.Print “In Table ” & tbl.Name ‘& ”      ” & tbl.DateCreated & ”      ” & tbl.LastUpdated & ”     ” & tbl.RecordCount
allDesc = allDesc & vbNewLine & “Table:” & tbl.Name
‘ optional code to print all the fields
On Error Resume Next
For Each fld In tbl.Fields
‘Debug.Print fld.Name
allDesc = allDesc & vbNewLine & fld.Name & “:” & fld.Properties(“Description”)
Next fld
End If
Next tbl

WriteToATextFile (allDesc)
End Function

Sub WriteToATextFile(ByVal outputStr)
‘first set a string which contains the path to the file you want to create.
‘this example creates one and stores it in the root directory
Dim MyFile As String
MyFile = “c:\” & “TableFieldsWithDesc.txt”
‘set and open file for output
Dim fnum As Integer
fnum = FreeFile()
Open MyFile For Output As fnum
‘write project info and then a blank line. Note the comma is required
Write #fnum, outputStr
Write #fnum,
Close #fnum
End Sub[/cc]
