第一种方法:
string str="server=.;uid=sa;pwd=111111;database=text_db";//连接字符串
SqlConnection SCON = null;//连接对象
SqlCommand SCom=new SqlCommand();//命令对象
SCON=new SqlConnection(str);
SCON.Open();
SCom.CommandText = "insert into cum(nm,age,sex,addr) values(‘”+name1+”’, ‘”+age1+”’, ‘”+sex1”’,’”+addr1+”’); insert into cum(nm,age,sex,addr) values(‘”+name1+”’, ‘”+age1+”’, ‘”+sex1”’,’”+addr1+”’)";
SCom.Connection = SCON;
SCom.CommandType = CommandType.Text;
int num = SCom.ExecuteNonQuery();
SCON.Close();
注意:这种执行我不推荐这也就是把多条sql语句写成了一条sql语句就行执行(大家如果要一次连接想执行多条sql语句那用下面的)
第二种方法:
string str="server=.;uid=sa;pwd=111111;database=text_db";//连接字符串
SqlConnection SCON;
SqlCommand SCom1=new SqlCommand();//要执行sql语句的第一个命令对象
SqlCommand SCom2=new SqlCommand();//要执行sql语句的第二个命令对象
SCON=new SqlConnection(str);
SCON.Open();
//第一条要执行的sql语句
SCom1.CommandText = "insert into cum(nm,age,sex,addr) values(@name,@age,@sex,@addr)";
SCom1.Parameters.Add("@name", SqlDbType.Text);
SCom1.Parameters.Add("@age", SqlDbType.Int);
SCom1.Parameters.Add("@sex", SqlDbType.Bit);
SCom1.Parameters.Add("@addr", SqlDbType.Text);
SCom1.Parameters["@name"].Value = name1;
SCom1.Parameters["@age"].Value = age1;
SCom1.Parameters["@sex"].Value = sex1;
SCom1.Parameters["@addr"].Value = addr1;
SCom1.Connection = SCON;
SCom1.CommandType = CommandType.Text;
int num = SCom1.ExecuteNonQuery();
//第二条要招行的sql语句
SCom2.CommandText = "insert into cum(nm,age,sex,addr) values(@name,@age,@sex,@addr)";
SCom2.Parameters.Add("@name", SqlDbType.Text);
SCom2.Parameters.Add("@age", SqlDbType.Int);
SCom2.Parameters.Add("@sex", SqlDbType.Bit);
SCom2.Parameters.Add("@addr", SqlDbType.Text);
SCom2.Parameters["@name"].Value = name2;
SCom2.Parameters["@age"].Value = age2;
SCom2.Parameters["@sex"].Value = sex2;
SCom2.Parameters["@addr"].Value = addr2;
SCom2.Connection = SCON;
SCom2.CommandType = CommandType.Text;
int num = SCom2.ExecuteNonQuery();
SCON.Close();
这种方法就是利用了一个SqlConnection对象进行一次连接,在关闭前执行多个SqlCommand命令对象,执行在进行关闭连接
