读取Excel的记录并导入SQL数据库
当前位置:点晴教程→知识管理交流

准备一下,近段时间,需要把Excel的数据导入数据库中。 using System.Configuration; using System.Data; using System.Data.OleDb; using System.Data.SqlClient;
你可以写一个方法,是去读取Excel文档的方法,返回DataSet数据集:
private DataSet ImportExcelToDataSet(string virtualPath, string sqlQueryStatement) { string excelConnectionString = DB.ExcelConnectionString(Server.MapPath(virtualPath)); OleDbConnection dc = new OleDbConnection(excelConnectionString); OleDbDataAdapter da = new OleDbDataAdapter(sqlQueryStatement, dc); DataSet ds = new DataSet(); da.Fill(ds); return ds; }
try { string cs = ConfigurationManager.ConnectionStrings["InsusSqlConnectionString"].ConnectionString; using (SqlConnection sqlConn = new SqlConnection(cs)) { string sqlQueryStatement = "SELECT [Material],[Plnt],[Level],[Item],[Component],[Object description] FROM [Sheet1$]"; string virtualPath = "~/App_Data/Book1.xlsx"; DataSet ds = ImportExcelToDataSet(virtualPath, sqlQueryStatement); DataTable dt = ds.Tables[0]; sqlConn.Open(); using (SqlBulkCopy sqlbc = new SqlBulkCopy(sqlConn)) { sqlbc.DestinationTableName = "BOM"; sqlbc.ColumnMappings.Add("Material", "Material"); sqlbc.ColumnMappings.Add("Plnt", "Plnt"); sqlbc.ColumnMappings.Add("Level", "Level"); sqlbc.ColumnMappings.Add("Item", "Item"); sqlbc.ColumnMappings.Add("Component", "Component"); sqlbc.ColumnMappings.Add("Object description", "Object description"); sqlbc.WriteToServer(dt); Response.Write("数据导入成功!"); } } } catch (Exception ex) { throw ex; }
下面内容于2017-10-17 14:38分添加: private OleDbDataReader ImportExcelToDataReader(string virtualPath, string sqlQueryStatement) { string excelConnectionString = DB.ExcelConnectionString(Server.MapPath(virtualPath)); OleDbConnection oleConn = new OleDbConnection(excelConnectionString); OleDbCommand oleComm = new OleDbCommand(sqlQueryStatement, oleConn); oleConn.Open(); return oleComm.ExecuteReader(); }
string sqlQueryStatement = "SELECT [Material],[Plnt],[Level],[Item],[Component],[Object description] FROM [Sheet1$]"; string virtualPath = "~/App_Data/Book1.xlsx"; string cs = ConfigurationManager.ConnectionStrings["InsusSqlConnectionString"].ConnectionString; SqlConnection sqlConn = new SqlConnection(cs); OleDbDataReader reader = ImportExcelToDataReader(virtualPath, sqlQueryStatement); using (SqlBulkCopy bulkCopy = new SqlBulkCopy(sqlConn)) { bulkCopy.DestinationTableName = "BOM"; try { sqlConn.Open(); bulkCopy.WriteToServer(reader); Response.Write("数据导入成功。"); } catch (Exception ex) { Console.WriteLine(ex.Message); } finally { reader.Close(); sqlConn.Close(); } } 该文章在 2017/11/16 23:48:37 编辑过 |
