目前数据库内已有大量数据，需把编号相同的但其他数据不同的 N行数据；提取出来写进WINCC MSHFlexGrid控件里，请问对SQL的查询脚本和查询按钮的VB脚本该怎样写，最好带有时间范围筛选。
基于GPT和Monster组的调写：
确定您使用的数据库类型。下面以使用 SQL Server 为例：
SQL 查询脚本：
SELECT DISTINCT id, field1, field2, ..., fieldN
FROM table_name
WHERE date BETWEEN start_date AND end_date
GROUP BY id, field1, field2, ..., fieldN
HAVING COUNT(*) = 1
VB 查询按钮脚本：
Private Sub QueryButton_Click()
Dim conn As New ADODB.Connection
Dim rs As New ADODB.Recordset
Dim strSQL As String
strSQL = "SELECT DISTINCT id, field1, field2, ..., fieldN " & _
"FROM table_name " & _
"WHERE date BETWEEN #" & startDate & "# AND #" & endDate & "# " & _
"GROUP BY id, field1, field2, ..., fieldN " & _
"HAVING COUNT(*) = 1"
conn.Open "Provider=SQLOLEDB;Data Source=yourServerName;Initial Catalog=yourDBName;User ID=yourUsername;Password=yourPassword;"
rs.Open strSQL, conn
' 将查询结果写入 MSHFlexGrid 控件
With MSHFlexGrid
.Clear
.Columns = rs.Fields.Count
.Rows = 1
For i = 0 To rs.Fields.Count - 1
.TextMatrix(0, i) = rs.Fields(i).Name
Next
.Rows = .Rows + 1
.TextMatrix(1, 0) = rs(0).Value
.TextMatrix(1, 1) = rs(1).Value
...
.TextMatrix(1, N) = rs(N).Value
rs.MoveNext
While Not rs.EOF
.Rows = .Rows + 1
.TextMatrix(.Rows - 1, 0) = rs(0).Value
.TextMatrix(.Rows - 1, 1) = rs(1).Value
...
.TextMatrix(.Rows - 1, N) = rs(N).Value
rs.MoveNext
Wend
End With
rs.Close
conn.Close
End Sub

首先，关于 SQL 的查询脚本，如果你想查询编号相同的数据，并且按照时间范围进行筛选，可以使用下面的 SQL 语句：
SELECT *
FROM table_name
WHERE code = 'your code' AND time BETWEEN 'start_time' AND 'end_time'
GROUP BY code
HAVING COUNT(*) > 1
其中，table_name是表名，code是编号列的列名，time是时间列的列名，start_time和end_time分别是开始时间和结束时间，请根据实际情况自行修改。
关于 VB 的查询按钮脚本，可以使用 ADO 或者 DAO 等数据访问方式，以下是一个使用 ADO 的示例：
Private Sub Command1_Click()
Dim conn As New ADODB.Connection
Dim rs As New ADODB.Recordset
conn.Open "Provider=SQLOLEDB;Data Source=your_server;Initial Catalog=your_database;User ID=your_username;Password=your_password;"
rs.Open "SELECT * FROM table_name WHERE code = 'your code' AND time BETWEEN 'start_time' AND 'end_time' GROUP BY code HAVING COUNT(*) > 1", conn, adOpenStatic, adLockReadOnly
MSHFlexGrid1.Clear
MSHFlexGrid1.Cols = rs.Fields.Count
MSHFlexGrid1.Rows = 1
For i = 0 To rs.Fields.Count - 1
MSHFlexGrid1.Col = i
MSHFlexGrid1.Text = rs.Fields(i).Name
Next
MSHFlexGrid1.Rows = 2
Do While Not rs.EOF
For i = 0 To rs.Fields.Count - 1
MSHFlexGrid1.Col = i
MSHFlexGrid1.Row = MSHFlexGrid1.Rows - 1
MSHFlexGrid1.Text = rs.Fields(i).Value
Next
MSHFlexGrid1.Rows = MSHFlexGrid1.Rows + 1
rs.MoveNext
Loop
rs.Close
conn.Close
End Sub
SELECT * FROM TableName WHERE ID IN (SELECT DISTINCT ID FROM TableName WHERE Date BETWEEN StartDate AND EndDate)；
VB脚本应该是：Dim conn As New ADODB.Connection conn.Open "Provider=SQLOLEDB;Data Source=ServerName;Initial Catalog=DBName;User Id=UserName;Password=Password" Dim rs As New ADODB.Recordset rs.Open "SELECT * FROM TableName WHERE ID IN (SELECT DISTINCT ID FROM TableName WHERE Date BETWEEN '" & StartDate & "' AND '" & EndDate & "')", conn, adOpenStatic, adLockOptimistic MSHFlexGrid1.DataSource = rs MSHFlexGrid1.Refresh.
你需要用 SQL 查询语句从数据库中选择出编号相同且其他数据不同的 N 行数据。下面是一个示例的 SQL 查询语句，该语句查询编号为 X 的数据，并限制时间范围为从 “start_time” 到 “end_time”：
SELECT * FROM table_name
WHERE id = X
AND time BETWEEN 'start_time' AND 'end_time'
GROUP BY id
HAVING COUNT(*) > 1;
对于查询按钮的 VB 脚本，你可以这样写：
Private Sub btnQuery_Click()
Dim con As New ADODB.Connection
Dim rs As New ADODB.Recordset
Dim start_time As Date, end_time As Date
' 设置连接字符串，这里以 SQL Server 为例
con.Open "Driver={SQL Server};Server=.\SQLExpress;Database=test;Trusted_Connection=yes;"
' 设置时间范围
start_time = CDate(Me.txtStartTime.Text)
end_time = CDate(Me.txtEndTime.Text)
' 执行 SQL 查询语句
rs.Open "SELECT * FROM table_name WHERE id = X AND time BETWEEN '" & start_time & "' AND '" & end_time & "' GROUP BY id HAVING COUNT(*) > 1;", con
' 将查询结果写入 WINCC MSHFlexGrid 控件
Me.MSHFlexGrid1.Clear
Me.MSHFlexGrid1.Rows = 1
While Not rs.EOF
Me.MSHFlexGrid1.Rows = Me.MSHFlexGrid1.Rows + 1
For i = 0 To rs.Fields.Count - 1
Me.MSHFlexGrid1.TextMatrix(Me.MSHFlexGrid1.Rows - 2, i) = rs.Fields(i).Value
Next i
rs.MoveNext
Wend
' 关闭数据库连接
rs.Close
con.Close
End Sub
请注意，上面的代码仅供参考，请根据你的数据库连接情况和实际需求
作者根据资料编写的程序已经可已根据AD查询数据，但我对查出来的数据进行时间段限制，应该怎么修改，我SQL里的记录的时间列名为 时间
'---------------------打开数据库 --------------------'
sCon= "Provider=SQLOLEDB; Integrated Security =SSPI;Persist Security Info=False; Initial Catalog=生产统计; Data Source=ZKCD\WINCC"
Set conn=CreateObject("ADODB.Connection")
conn.ConnectionString = sCon
conn.CursorLocation = 3
conn.Open
Set oRs1 = CreateObject("ADODB.Recordset")
Set oCom = CreateObject("ADODB.Command")
oCom.CommandType = 1
'---------------------查询数据库 --------------------'
strSQL1= "SELECT * FROM [当日生产统计]"
strSQL1 = strSQL1 & " WHERE AD = '" & DATE1 & "'"
Set oCom.ActiveConnection = conn
oCom.CommandText = strSQL1
Set oRs1 = oCom.Execute
SQL查询脚本：
SELECT * FROM TableName WHERE ID in (Select ID From TableName Group by ID HAVING count(*) > 1) AND date BETWEEN dateFrom and dateTo;
VB脚本：
Sub Query_Click()
Dim strSQL As String
strSQL = "SELECT * FROM TableName WHERE ID in (Select ID From TableName Group by ID HAVING count(*) > 1) And date BETWEEN '"& dateFrom & "' And '" & dateTo & "'"
MSHFlexGrid.DataSource = strSQL
MSHFlexGrid.Refresh
End Sub
