我要评论1.获取return返回值
复制代码 代码如下:
//存储过程
//create procedure mysql
// @a int,
// @b int
//as
// return @a + @b
//go
sqlconnection conn = new sqlconnection(configurationmanager.connectionstrings["localsqlserver"].tostring());
conn.open();
sqlcommand mycommand = new sqlcommand("mysql", conn);
mycommand.commandtype = commandtype.storedprocedure;
mycommand.parameters.add(new sqlparameter("@a", sqldbtype.int));
mycommand.parameters["@a"].value = 10;
mycommand.parameters.add(new sqlparameter("@b", sqldbtype.int));
mycommand.parameters["@b"].value = 20;
mycommand.parameters.add(new sqlparameter("@return", sqldbtype.int));
mycommand.parameters["@return"].direction = parameterdirection.returnvalue;
mycommand.executenonquery();
response.write(mycommand.parameters["@return"].value.tostring());
2.获取output输出参数值
复制代码 代码如下:
//存储过程
//create procedure mysql
// @a int,
// @b int,
// @c int output
//as
// set @c = @a + @b
//go
sqlconnection conn = new sqlconnection(configurationmanager.connectionstrings["localsqlserver"].tostring());
conn.open();
sqlcommand mycommand = new sqlcommand("mysql", conn);
mycommand.commandtype = commandtype.storedprocedure;
mycommand.parameters.add(new sqlparameter("@a", sqldbtype.int));
mycommand.parameters["@a"].value = 20;
mycommand.parameters.add(new sqlparameter("@b", sqldbtype.int));
mycommand.parameters["@b"].value = 20;
mycommand.parameters.add(new sqlparameter("@c", sqldbtype.int));
mycommand.parameters["@c"].direction = parameterdirection.output;
mycommand.executenonquery();
response.write(mycommand.parameters["@c"].value.tostring());
c#接收存储过程返回值:
复制代码 代码如下:
public static int user_add(user us)
{
int iret;
sqlconnection conn = new sqlconnection(conn_str);
sqlcommand cmd = new sqlcommand("user_add", conn);
cmd.commandtype = commandtype.storedprocedure;
cmd.parameters.addwithvalue("@uname", us.uname);
cmd.parameters.addwithvalue("@upass", us.upass);
cmd.parameters.addwithvalue("@passquestion", us.passquestion);
cmd.parameters.addwithvalue("@passkey", us.passkey);
cmd.parameters.addwithvalue("@email", us.email);
cmd.parameters.addwithvalue("@rname", us.rname);
cmd.parameters.addwithvalue("@area", us.area);
cmd.parameters.addwithvalue("@address", us.address);
cmd.parameters.addwithvalue("@zipcodes", us.zipcodes);
cmd.parameters.addwithvalue("@phone", us.phone);
cmd.parameters.addwithvalue("@qq", us.qq);
cmd.parameters.add("@return_value", "").direction = parameterdirection.returnvalue;
try
{
conn.open();
cmd.executenonquery();
iret = (int)cmd.parameters["@return_value"].value;
}
catch (sqlexception ex)
{
throw ex;
}
finally
{
conn.close();
}
return iret;
}
c#接收存储过程输出参数:
复制代码 代码如下:
public static decimal cart_useramount(int uid)
{
decimal iret;
sqlconnection conn = new sqlconnection(conn_str);
sqlcommand cmd = new sqlcommand("cart_useramount", conn);
cmd.commandtype = commandtype.storedprocedure;
cmd.parameters.addwithvalue("@uid", uid);
cmd.parameters.add("@amount", sqldbtype.decimal).direction=parameterdirection.output;
try
{
conn.open();
cmd.executenonquery();
iret = (decimal)cmd.parameters["@amount"].value;
}
catch (sqlexception ex)
{
throw ex;
}
finally
{
conn.close();
}
return iret;
}
