Excel数据生成Sql语句的方法

选中想要生成的列，套用表格格式，选中表包含标题的选项确定，然后在最右边的一列第二行处，点击函数功能，选择CONCATENATE，在文本里输入想要的结构即可

代码如下	复制代码
，=CONCATENATE("('",[@id],"','",[@name],"'),")

这样生成的之后的语句可以写为

代码如下	复制代码
insert table1 (id,name) values ('1', "测试1"),('2', "测试2")...

如果你会C#我们可以使用OleDb读取Excel并生成SQL语句

代码如下

复制代码

using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.IO; using System.Reflection; using Excel = Microsoft.Office.Interop.Excel; using System.Data; using System.Data.OleDb; using System.Windows.Forms; namespace ReadXlsxData {     static class ParseXlsx     {         public static readonly int COMMENT_INDEX=4;   //字段说明行下标         public static readonly int KEY_INDEX = 5;    //主键行下标         public static readonly int TYPE_INDEX = 6;   //字段类型行下标         public static readonly int SQLNAME_INDEX = 7;      //数据库字段名行下标         public static readonly int VALUE_INDEX = 8;      //value 行下标         public static StringBuilder objectData = new StringBuilder();         public static DataTable ToDataSet(string filePath)         {             string connStr = "";                        string fileType = System.IO.Path.GetExtension(filePath);             if (string.IsNullOrEmpty(fileType)) return null;             if (fileType == ".xls")                 connStr = "Provider=Microsoft.Jet.OLEDB.4.0;" + "Data Source=" + filePath + ";" + ";Extended Properties="Excel 8.0;HDR=NO;IMEX=1"";             else                 connStr = "Provider=Microsoft.ACE.OLEDB.12.0;" + "Data Source=" + filePath + ";" + ";Extended Properties="Excel 12.0;HDR=NO;IMEX=1"";             string sql_F = "Select * FROM [{0}]";             OleDbConnection conn = null;             OleDbDataAdapter da = null;             DataTable dataTable = new DataTable();             try             {                 // 初始化连接，并打开   www.111cn.net                               conn = new OleDbConnection(connStr);                 conn.Open();                 da = new OleDbDataAdapter();                 da.SelectCommand = new OleDbCommand(String.Format(sql_F, "Sheet1$"), conn);                 da.Fill(dataTable);             }             catch (Exception ex)             { }             finally             {                  // 关闭连接                                  if (conn.State == ConnectionState.Open)                 {                     conn.Close();                     da.Dispose();                     conn.Dispose();                 }             }             conn.Close();             da.Dispose();             conn.Dispose();             return dataTable;         }         public static string ReadExcelFile(string namef, string sqlfile, string sqlcomment)         {             objectData.Clear();             DataTable dt = ToDataSet(namef);             string temp, key,temp1,temp2;             List<int> index = new List<int>();                      //创建表头             objectData.Append("DROP TABLE IF EXISTS `" + sqlfile + "`;n");             objectData.Append("CREATE TABLE `" + sqlfile + "` (n");             int columnSize = dt.Columns.Count;             int rowSize = dt.Rows.Count;             DataColumn dc;             DataRow dr;             temp = string.Empty;             key = string.Empty;             temp1 = string.Empty;             temp2 = string.Empty;             DataRow dr5 = dt.Rows[COMMENT_INDEX],dr9=dt.Rows[SQLNAME_INDEX],dr8=dt.Rows[TYPE_INDEX];             for (int i = 1; i < columnSize; i++)             {                 dc = dt.Columns[i];                 temp2 = dr5[dc].ToString();                 temp1 = dr9[dc].ToString();                 if (temp2 == string.Empty)//空列判断                     break;                 else if (temp1.ToString() != string.Empty)  //数据库字段                 {                     index.Add(i);                     temp = dr8[dc].ToString();                     if (temp.Contains("vachar"))                         objectData.Append("t`" + temp1 + "` " + temp + " NOT NULL DEFAULT '' COMMENT '" + temp2 + "',n");                     else                         objectData.Append("t`" + temp1 + "` " + temp + " NOT NULL DEFAULT '0' COMMENT '" + temp2 + "',n");                     temp = dt.Rows[KEY_INDEX][dc].ToString();                     if (temp != null && temp.Contains("key"))                     {                         key += "`" + temp1 + "` "; } }             }             if(key!=string.Empty)                 objectData.Append("tPRIMARY KEY (" + key + ")n");             objectData.Append(") ENGINE=InnoDB DEFAULT CHARSET=utf8 COMMENT='" + sqlcomment + "';n");             for (int i = VALUE_INDEX; i < rowSize; i++)   //读取数据记录             {                 objectData.Append("INSERT INTO `" + sqlfile + "` VALUES ('");                 dr = dt.Rows[i];                 int length = index.Count;                 for (int j = 0; j < length; j++)                 {                     objectData.Append(dr[index[j]] + "','");                 }                 objectData.Remove(objectData.Length - 3, 2);                 objectData.Append(");n");             }              return objectData.ToString();         }     }

}

最终导出结果如下
