第一種方法:

???????? ?? string str="server=.;uid=sa;pwd=111111;database=text_db";//連接字符串

??????? SqlConnection SCON = null;//連接對(duì)象

??????? SqlCommand SCom=new SqlCommand();//命令對(duì)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：這種執(zhí)行我不推薦這也就是把多條sql語(yǔ)句寫成了一條sql語(yǔ)句就行執(zhí)行（大家如果要一次連接想執(zhí)行多條sql語(yǔ)句那用下面的）

?

第二種方法:

?

?????? string str="server=.;uid=sa;pwd=111111;database=text_db";//連接字符串

??????? SqlConnection SCON;

??????? SqlCommand SCom1=new SqlCommand();//要執(zhí)行sql語(yǔ)句的第一個(gè)命令對(duì)象

???? ?? SqlCommand SCom2=new SqlCommand();//要執(zhí)行sql語(yǔ)句的第二個(gè)命令對(duì)象

??????????? SCON=new SqlConnection(str);

??????????? SCON.Open();

?????????? //第一條要執(zhí)行的sql語(yǔ)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();

???????? ?//第二條要招行的sql語(yǔ)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();

?? 這種方法就是利用了一個(gè)SqlConnection對(duì)象進(jìn)行一次連接，在關(guān)閉前執(zhí)行多個(gè)SqlCommand命令對(duì)象，執(zhí)行在進(jìn)行關(guān)閉連接
