关于Oracle和SQLServer数据库在.net中拼接数据库语句的不同

1             StringBuilder strSql=new StringBuilder();
2             strSql.Append("insert into Books(");
3             strSql.Append("Title,Author,PublisherId)");
4             strSql.Append(" values (");
5             strSql.Append("@Title,@Author,@PublisherId)");
6             strSql.Append(";select @@IDENTITY");
7             SqlParameter[] parameters = {
8                     new SqlParameter("@Title", SqlDbType.NVarChar,200),
9                     new SqlParameter("@Author", SqlDbType.NVarChar,200),
10                     new SqlParameter("@PublisherId", SqlDbType.Int,4)};
11             parameters[0].Value = model.Title;
12             parameters[1].Value = model.Author;
13             parameters[2].Value = model.Publisher.Id ;

15             object obj = DbHelperSQL.GetSingle(strSql.ToString(),parameters);
16             if (obj == null)
17             {
18                 return 1;
19             }
20             else
