sql-server - Automate Importing Multiple Excel Worksheets into SQL

Question

I need to allow a user to select an Excel file, and then upload All Worksheets to a SQL table. I'm not sure how to do this. The format of each sheet is exactly the same. And the worksheet format matches the SQL table format.

Answer 1

您可以将 ODBC 提供程序用于 Excel 文件。这是一些用 javascript 编写的代码，用于将 Excel 文件导入 SQL Server 表。每个工作表都被视为一个表格。数据类型存在一些问题，因为 ODBC 驱动程序通过读取每列的第一个值来推断每列的数据类型，因此如果列的第一行数据中有数字，则整列将被读取为数字，并且每个“非数字”值将被读取为 NULL。

var objCat = new ActiveXObject("ADODB.Connection"); 
var objRSExcel = Server.CreateObject("ADODB.Recordset");
objRSExcel.CursorLocation = 3;
var file =  "imported_file.xls";
var TableName = "[Sheet1$]"

// Database Creation
objCat.ConnectionString = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + file + ";Extended Properties=Excel 8.0;";                    
objCat.Open();
objRSExcel.Open("SELECT * FROM " + TableName, objCat);

var rsInsert = Server.CreateObject("ADODB.Recordset");
rsInsert.Open("SELECT * FROM [TARGET_TABLE]", cn, 1, 3);

while (!objRSExcel.EOF) {
    rsInsert.AddNew();
    for (var j=0;j<objRSExcel.Fields.Count; j++) {
        rsInsert.Fields(j).Value = objRSExcel.Fields(j).Value;
    }
    rsInsert.Update();
    objRSExcel.MoveNext();
}
objRSExcel.Close();
rsInsert.Close();
