C 運算元據庫備份和還原

c#實現sqlserver2000資料庫備份還原的兩種方法

: 方法一（不使用sqldmo）：
//////備份方法
///sqlconnection conn = new sqlconnection("server=.;database=master;user id=sa;password=sa;");
sqlcommand cmdbk = new sqlcommand();
cmdbk.commandtype = commandtype.text;
cmdbk.connection = conn;
cmdbk.commandtext = @"backup database test to disk='c:ba' with init";
trycatch(exception ex)
finally
//////還原方法
///sqlconnection conn = new sqlconnection("server=.;database=master;user id=sa;password=sa;trusted_connection=false");
conn.open();
//kill database process
sqlcommand cmd = new sqlcommand("select spid from sysprocesses ,sysdatabases where sysprocesses.dbid=sysdatabases.dbid and sysdatabases.name='test'", conn);
sqldatareader dr;
dr = cmd.executereader();
arraylist list = new arraylist();
while(dr.read())
dr.close();
for(int i = 0; i < list.count; i++)
", list), conn);
cmd.executenonquery();
}sqlcommand cmdrt = new sqlcommand();
cmdrt.commandtype = commandtype.text;
cmdrt.connection = conn;
cmdrt.commandtext = @"restore database test from disk='c:ba'";
trycatch(exception ex)
finally
方法二（使用sqldmo）：
//////備份方法
/ backup = new sqldmo.backupclass();
sqldmo.sqlserver server = new sqldmo.sqlserverclass();
//顯示進度條
sqldmo.backupsink_percentcompleteeventhandler progress = new sqldmo.backupsink_percentcompleteeventhandler(step);
backup.percentcomplete += progress;
trycatch(exception ex)
finally
this.pbdb.value = 0;
//////還原方法
/ restore = new sqldmo.restoreclass();
sqldmo.sqlserver server = new sqldmo.sqlserverclass();
//顯示進度條
sqldmo.restoresink_percentcompleteeventhandler progress = new sqldmo.restoresink_percentcompleteeventhandler(step);
restore.percentcomplete += progress;
//kill database process
sqlconnection conn = new sqlconnection("server=.;database=master;user id=sa;password=sa;trusted_connection=false");
conn.open();
sqlcommand cmd = new sqlcommand("select spid from sysprocesses ,sysdatabases where sysprocesses.dbid=sysdatabases.dbid and sysdatabases.name='test'", conn);
sqldatareader dr;
dr = cmd.executereader();
arraylist list = new arraylist();
while(dr.read())
dr.close();
for(int i = 0; i < list.count; i++)
", list), conn);
cmd.executenonquery();
}conn.close();
trycatch(exception ex)
finally
this.pbdb.value = 0;

先從資料庫中取出結果集後進行處理資料後再update更新到資料庫。如果只想讀取和顯示資料，只需要使用資料讀取sqldatareader即可，但要處理資料然後更新資料庫 增加 更改 局需要資料集dataset和資料介面卡sqldataadaper。sqldataadapter的用法 讀取資料用sqld...
