ASP.NET中的数据库操作类sqlhelper及方法使用指南

要在VS2005中使用sqlhelper类,必须把Microsoft.ApplicationBlocks.Data.dll引用到项目中.

1.通过存储过程查询的方法SqlHelper.ExecuteDataset(数据库连接字符, 存储过程字符, 参数数组);

2.通过字符串查询的方法SqlHelper.ExecuteDataset(数据库连接字符, CommandType.Text , 查询字符串,参数数组);

3.通过存储过程插入的方法SqlHelper.ExecuteScalar(数据库连接字符, 存储过程字符, 参数数组);

4.通过字符串插入的方法SqlHelper.ExecuteScalar(数据库连接字符, CommandType.Text , 插入及刷新字符串,参数数组);

5.通过存储过程刷新的方法SqlHelper.ExecuteNonQuery(数据库连接字符, 存储过程字符, 参数数组);

6.通过字符串刷新的方法SqlHelper.ExecuteNonQuery(数据库连接字符, CommandType.Text , 刷新字符串,参数数组);
