[英]How do I create a dictionary from a specific table field?
I'm writing a script that will take data from text reports generated by a legacy system and import it into a more flexible tracking database.我正在编写一个脚本,该脚本将从遗留系统生成的文本报告中获取数据,并将其导入到更灵活的跟踪数据库中。 I'm trying to figure out how to build up a dictionary from data within a table so that I can quickly filter through the imported data using the dictionary exists method and only import the data belonging to my shop.
我试图弄清楚如何从表中的数据构建字典,以便我可以使用字典存在方法快速过滤导入的数据,并且只导入属于我的商店的数据。
I have a table called tblShop
that contains a field called [WorkcenterID]
.我有一个名为
tblShop
的表,其中包含一个名为[WorkcenterID]
的字段。 As my script runs, it's going to be extracting data from the text report, looking at the employee's work center, checking if that employee belongs to me (by comparing the extracted work center text to the dictionary), and if true, writes the data to an import table for further processing.当我的脚本运行时,它将从文本报告中提取数据,查看员工的工作中心,检查该员工是否属于我(通过将提取的工作中心文本与字典进行比较),如果为真,则写入数据到导入表以供进一步处理。

For the curious, here's my code:对于好奇,这是我的代码:
Private Sub Command5_Click()
Dim crscd, startdt, stopdt, starttm, stoptm, bldstr, rmstr, evtid, empn, empw As String
Dim i, cd, ci, es, ee As Integer
Dim cdb As DAO.Database
Dim imt, sht As DAO.Recordset
Dim wcDict As New Scripting.Dictionary
Set cdb = CurrentDb
Set imt = cdb.OpenRecordset("tblImport", dbOpenTable)
Set sht = cdb.OpenRecordset("tblShop", dbOpenTable)
'--- grab pasted text data from form ---
strText = Me.InData.Value
'--- split text data into array so we can read line by line ---
arrlines = Split(strText, vbCrLf)
'--- reset line counters ---
i = 0
ci = -1
cd = -1
es = -1
ee = -1
For Each strline In arrlines
'--- find location of course info ---
If Left(strline, 17) = "COURSE NARRATIVE" Then
cd = i + 2
End If
'--- find location of course location info & event ID
If Left(strline, 8) = "BUILDING" Then
ci = i + 1
End If
'--- find where assigned employee data starts
If Left(strline, 6) = "EMP NR" Then
es = i + 1
End If
'--- find where assigned employee data ends
If es > 0 And IsNumeric(Left(strline, 5)) = False Then
ee = i - 1
End If
'--- extract course code and start/stop dates/times
If i = cd Then
crscd = Left(strline, 6)
startdt = Left(Right(strline, 28), 7)
starttm = Left(Right(strline, 20), 4)
stopdt = Left(Right(strline, 15), 7)
stoptm = Left(Right(strline, 7), 4)
End If
'--- extract building number, room number and event ID
If i = ci Then
bldstr = Trim(Left(strline, 13))
rmstr = Trim(Left(Right(strline, 55), 9))
evtid = Trim(Left(Right(strline, 46), 9))
End If
i = i + 1
Next
'--- clear import table
DoCmd.SetWarnings False
DoCmd.RunSQL "DELETE * FROM tblImport"
DoCmd.SetWarnings True
'--- dump employee data to import table
For n = es To ee
empn = Left(Left(arrlines(n), 48), 5)
empw = Left(Right(Left(arrlines(n), 48), 11), 4)
'--- verfiy employee belongs to us before importing data
'If wcDict.exists(empw) = True Then
'imt.AddNew
'imt!EmpID = empn
'imt!Workcenter = empw
'imt.Update
'End If
Next
wcDict = Nothing
imt.Close
Set imt = Nothing
sht.Close
Set sht = Nothing
cdb.Close
Set cdb = Nothing
End Sub
The solution is to use the following code to loop through the recordset to extract the required data:解决方法是使用以下代码循环记录集提取所需数据:
sht.MoveFirst
Do While Not sht.EOF
empw = sht![WorkcenterID]
wcDict.Add empw, vbNullString
sht.MoveNext
Loop
empw = ""
Insert that before the pasted text data grab, uncomment the verify if
block at the bottom and it'll work.插入粘贴的文本数据抓取之前,取消对验证
if
块在底部,它会工作。
