Process process = new Process();
process.StartInfo.FileName = "cmd.exe";
process.StartInfo.UseShellExecute = false;
process.StartInfo.RedirectStandardInput = true;
process.StartInfo.RedirectStandardOutput = true;
process.StartInfo.RedirectStandardError = true;
process.StartInfo.CreateNoWindow = true;
process.Start();

command 参数可以输入如

net stop mssqlserver
代码是最好的文字，不多说，请看我的代码，并给分，呵呵。
--step1. 建表
if exists(select * from sysobjects where id=object_id('student') and objectproperty(id,'IsTable')=1)
drop table student
go
create table student
(
id int identity(100,10) not null
,sname varchar(10) not null
,sno varchar(30) not null
)
go
--step2.建存储过程
if exists(select * from sysobjects where id=object_id('proc_demo') and objectproperty(id,'IsProcedure')=1)
drop procedure proc_demo
go
create procedure proc_demo
@o_maxid int output
as
set nocount on
--如果希望大小写敏感，使用第一句，因为SQL Server默认是大小写不敏感的
--update student set sno='cay_'+sno where ascii(substring(sname,1,1))=87 and ascii(substring(sname,2,1))=65 and sno not like 'cay_%'
update student set sno='cay_'+sno where sname like 'WA%' and sno not like 'cay_%'
print convert(varchar(10),@@rowcount)+'条记录符合条件并被处理'
select @o_maxid=max(id) from student where id=100
if(@o_maxid is null) print '没有找到符合条件的最大记录'
set nocount off
go
--测试数据1
truncate table student
set identity_insert student on
insert into student(id,sname,sno)values(1,'WA1','1');
insert into student(id,sname,sno)values(2,'wa2','2');
insert into student(id,sname,sno)values(3,'3','3');
set identity_insert student off
go
--测试数据2
truncate table student
insert into student(sname,sno)values('WA1','1');
insert into student(sname,sno)values('wa2','2');
insert into student(sname,sno)values('3','3');
go
--测试过程
declare @maxid int
exec proc_demo @maxid out
print '最大id是'+convert(varchar(10),@maxid)

方法比较多，就说两种先
var i,j:Integer;
s:string;
myfile:textfile;
begin
with query1 do
begin
close;
sql.clear;
sql.add('select * from sb_fcs');
open;
end;
AssignFile(myfile,'d:\2.txt');
Rewrite(myfile);
try
for i:=0 to query1.recordcount-1 do
begin
for j:=0 to query1.FieldCount-1 do
BEGIN
s:=query1.fields[j].name+':'+query1.fields[i].asstring+',';
writeln(myfile,s);//myfile 为要写的txt文件
end;
query1.next;
end;
finally CloseFile(myfile);
END;
end;
方法二：
s1:string;
s:tstringlist;
with query1 do
begin
s1:='';
for i:=0 to fieldcount-1 do s1:=s1+fields[i].asstring+' ';
s.add(s1);
循环读入
next;
end;
s.savetofile('c:\a.txt');
