NHibernate 下 执行SQL语句 (原创)
public IList ExecuteSQLQuery(string sql) {
ITransaction trn = this._session.BeginTransaction();
try {
ISQLQuery sqlQuery = _session.CreateSQLQuery(sql);
int ss = sql.IndexOf(" ");
sql = sql.Substring(ss + 1);
int ee = sql.IndexOf(" from");
sql = sql.Substring(0, ee);
string[] filed = sql.Split(new char[] { ',' });
for (int i = 0; i < filed.Length; i++) {
if (filed[i].IndexOf("as") > 0) {
filed[i] = filed[i].Substring(filed[i].IndexOf("as") + 3).Trim();
}
sqlQuery.AddScalar(filed[i], NHibernateUtil.String);
}
IList resultList = sqlQuery.List();
trn.Commit();
return resultList;
} catch (Exception e) {
trn.Rollback();
throw e;
}
}
注意,此方法 的SQLSTR最好 字段和表明 都用别名,例如:select t1.filed1 as filed1,t1.field2 as field2 from table1 as t1 where t1.filed2>0;
