传入实体执行（可添加 修改 删除）事务。
IDbHelper
dbHelper = new OracleHelper(ConfigHelper.GetConfigString("BusinessDbConnection"));
bool result
= true;
try
{
dbHelper.BeginTransaction();
//主表
TE_AREAManager
manager = new TE_AREAManager(dbHelper,
userInfo);
TE_AREAEntity
tE_AREAEntity = manager.GetObject(dbHelper.SqlSafe(eatxtAREA_ID));
manager.Delete(tE_AREAEntity);
//子表 TE_AREA_SUBManager
submanager = new TE_AREA_SUBManager(dbHelper,
userInfo);
TE_AREA_SUBEntity
tE_AREA_SUBEntity = submanager.GetObject(dbHelper.SqlSafe(eatxtAREA_ID));
submanager.Delete(tE_AREA_SUBEntity);
//事务提交 dbHelper.CommitTransaction();
}
catch(Exception
ex)
{
//事务回滚 dbHelper.RollbackTransaction();
result=false;
}
可以传入sql语句执行事务IDbHelper
dbHelper = new OracleHelper(ConfigHelper.GetConfigString("BusinessDbConnection"));
bool result
= true;
try
{
dbHelper.BeginTransaction();
string commandText
= "
DELETE FROM TE_AREA WHERE ID=" +
dbHelper.SqlSafe(id);
dbHelper.ExecuteNonQuery(sqlString);
commandText
= "
DELETE FROM TE_AREA_SUB WHERE ID=" +
dbHelper.SqlSafe(id);
dbHelper.ExecuteNonQuery(commandText);
dbHelper.CommitTransaction();
}
catch(Exception
ex)
{
dbHelper.RollbackTransaction();
result=false;
}
还可以同时传入实体，SQL语句IDbHelper
dbHelper = new OracleHelper(ConfigHelper.GetConfigString("BusinessDbConnection"));
bool result
= true;
try
{
dbHelper.BeginTransaction();
//主表
TE_AREAManager
manager = new TE_AREAManager(dbHelper,
userInfo);
TE_AREAEntity
tE_AREAEntity = manager.GetObject(dbHelper.SqlSafe(eatxtAREA_ID));
manager.Delete(tE_AREAEntity);
//子表
TE_AREA_SUBManager
submanager = new TE_AREA_SUBManager(dbHelper,
userInfo);
TE_AREA_SUBEntity
tE_AREA_SUBEntity = submanager.GetObject(dbHelper.SqlSafe(eatxtAREA_ID));
submanager.Delete(tE_AREA_SUBEntity);
//执行SQL语句
string commandText
= "
DELETE FROM JINTIANDA WHERE ID=" +
dbHelper.SqlSafe(id);
dbHelper.ExecuteNonQuery(commandText); //事务提交
dbHelper.CommitTransaction();
}
catch(Exception
ex)
{
//事务回滚
dbHelper.RollbackTransaction();
result=false;
}
