下面的代码可以根据excel文件，生成创建表的SQL，以及测试InsertSQL 。方法将excel数据创建到SQL table 中
private void GetExcelFile(string path, string folder = "")
{
StringBuilder sb = new StringBuilder();
//loadfile
Workbook workbook = new Workbook(path);
for (int i = 0; i < workbook.Worksheets.Count; i++)
{
var sheetName = workbook.Worksheets[i].Name;
sb.AppendFormat("create table [BIUPload_{0}] (", sheetName);
sb.AppendLine();
Cells cells = workbook.Worksheets[i].Cells;
#region create sql
StringBuilder sql_log = new StringBuilder();
StringBuilder sql_insert = new StringBuilder();
sql_insert.AppendFormat("insert BIUPload_{0} (", sheetName);
for (int c = 0; c < cells.MaxDataColumn + 1; c++)
{
if (cells[0, c] != null && cells[0, c].Value != null)
{
var colname = cells[0, c].Value.ToString();
//sb.AppendLine("colname:" + colname);
sb.AppendFormat("[{0}] nvarchar(20) ,", colname);
sb.AppendLine();
if (c == 0)
{
sql_insert.AppendFormat("[{0}]", colname);
}
else
{
sql_insert.AppendFormat(",[{0}]", colname);
}
sql_insert.AppendLine();
}
}
sb.AppendLine(")");
sql_insert.AppendLine(")");
#endregion
#region create values
for (int r = 1; r <= cells.MaxDataRow; r++)
{
var sql_values = new StringBuilder();
sql_values.AppendLine(sql_insert.ToString());
sql_values.AppendLine(" values (");
sql_log.AppendLine(sql_values.ToString());
List<SqlParameter> parameters = new List<SqlParameter>();
for (int c = 0; c < cells.MaxDataColumn + 1; c++)
{
var pName = "@P" + c;
if (cells[r, c] != null && cells[r, c].Value != null)
{
var value = cells[r, c].Value.ToString().Trim();
SqlParameter sqlParameter = new SqlParameter(pName, value);
parameters.Add(sqlParameter);
if (c == 0)
{
sql_values.AppendFormat("{0}", pName);
sql_log.AppendFormat("‘{0}‘", value);
}
else
{
sql_values.AppendFormat(",{0}", pName);
sql_log.AppendFormat(",‘{0}‘", value);
}
}
else
{
if (c == 0)
{
sql_values.AppendFormat("‘‘");
sql_log.AppendFormat("‘‘");
}
else
{
sql_values.AppendFormat(",‘‘");
sql_log.AppendFormat("‘‘");
}
}
}
sql_values.AppendLine(" )");
sql_log.AppendLine(" )");
SqlHelper.ExecuteNonQuery(_connString, CommandType.Text, sql_values.ToString(), parameters.ToArray());
}
#endregion
//insert values
#region insertSql
var sqlFile = File.Create(Path.Combine(folder, sheetName+DateTime.Now.ToString("yyyyMMddHHmmss") + ".sql"));
StreamWriter sw2 = new StreamWriter(sqlFile);
string excuteSQL = delete + sql_log.ToString();
// SqlHelper.ExecuteNonQuery(_connString, System.Data.CommandType.Text, excuteSQL);
sw2.WriteLine(excuteSQL);
sw2.Flush();
sw2.Close();
sqlFile.Close();
#endregion
}
#region create table
var file = File.Create( Path.Combine(folder, DateTime.Now.ToString("yyyyMMddHHmmss") + "entity.txt"));
StreamWriter sw = new StreamWriter(file);
sw.WriteLine(sb.ToString());
sw.Flush();
sw.Close();
file.Close();
#endregion
}
Aspose 直接插入SQL Server DataTalbe
