将那么多行读入记录集中,因为在 Excel 文件的 B 列中使用了单元格,使用 ADODB 连接 EXCEL;

Read that many rows into the recordset, as there are used cells in column B in Excel file, using ADODB connection with EXCEL;

最重要的是,代码是用 Word VBA 编辑器编写的,它是从 Word .docm 文件中提取的。

我从这个 Word .docm 文件连接到 Excel 文件(使用 ADODB 连接),它作为客户端数据库,我正在从该文件读取整个 sheet (sheet name = "data") 到动态数组中,稍后将搜索。

问题在于,在这个 Excel 文件中,A 列中有一个索引号,它是使用系列填充手动预填充的,直到第 70000 行。同时,从B列开始的真实数据只有182行。

所以问题是:如何仅检索从该文件中提取的记录集中已有效填充(B 列中最后使用的行)的行数- 当然没有打开文件。并使用 EXCEL.

的 ADODB 连接

我问这个问题是因为在后面的代码中,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),稍后我将需要它来搜索和填充自动生成word文件。

这是我目前得到的代码:(宏将从 Word 文件中获取)

假设我的 Excel 文件 (Worksheets("data")) 中有 182 个有效填充行 - 在第一个空单元格之前,B 列或 C 列中没有空白单元格B 或 C 列中的单元格,目前将是“B183”和“C183”,但随着新客户数据填充后续行,这些列中的第一个空单元格会发生变化。

但永远不会出现 B 列和 C 列中除了第一个空单元格之外还有空白单元格的情况。

您的连接字符串表示您的列在单元格的第一行中有名称。

假设 B 列称为“mycolumn”

那么你需要改变

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"
