使用ADODB与EXCEL的连接,将这么多行读入记录集,因为Excel文件的B列中使用了单元格;

问题描述

最重要的是,代码是用Word VBA编辑器编写的,并且是从Word .docm文件获取的。

从这个Word .docm文件中,我正在连接到用作客户端数据库的Excel文件(使用ADODB连接),并且正在从该文件(工作表名称=“数据”)中读取整个工作表到动态数组,稍后将进行搜索

问题是,在此Excel文件中,A列中有一个索引号,该索引号是手动填充的,使用系列填充,直到第70000行。同时,从B列开始的实际数据仅填充182行。

所以问题是:如何仅检索有效填充的行数(B列中最后使用的行)到从该文件提取的记录集中-当然不打开文件。并在EXCEL中使用ADODB连接。

我问这个问题,因为在代码的后面,我需要记录集中的行数才能将其写入动态数组(使用ReDim语句),稍后我将需要搜索并填充单词文件自动

这是我到目前为止获得的代码:(宏将从Word文件中午餐)

arraySize = recSet.RecordCount   'I wanted to assign total number of records to arraySize variable to use it later in ReDim statement.
Debug.Print arraySize

ReDim strArray(1 To arraySize)
For i = 1 To arraySize
   strArray(i) = recSet(i)
Next i

intRow = 2

'  For Each cntCntrl In ActiveDocument.ContentControls

'    If cntCntrl.Title = "02KlientNrDowodu" Then cntCntrl.Range.Text = objExcel.Sheets("data").Cells(intWiersz,9)
'  Next

假设我的Excel文件(Worksheets(“ data”))中有效填充了182行-B或C列中没有空白单元格,直到B或C列中的第一个空单元格都将是“ B183”和“ C183”,但这些列中的第一个空单元格会发生变化,因为新的客户数据会填充随后的行。

但是永远不会出现这样的情况:B和C列中有空白单元格,而不是这些列中的第一个空单元格。

解决方法

您的连接字符串表示您的列在单元格的第一行中都有名称。

假设列B被称为“ mycolumn”

然后您需要更改

strQuery = "SELECT * From [data$]"

strQuery = "SELECT * From [data$] WHERE mycolumn <> ''"

或者您可能需要

strQuery = "SELECT * From [data$] WHERE mycolumn <> '' AND mycolumn IS NOT NULL"
