ddtek.oracle.dll使用相关

ddtek.oracle.dll 可以不安装Oracle客户端，直接使用其来登录Oracle服务器，

 

数据库连接（后面一种为双机集群）：

var conn = new DDTek.Oracle.OracleConnection();
conn.ConnectionString = "Host=172.16.1.32;Port=1521;User ID=slmesuser;Password=slmesuser;Service Name=tqmes";
conn.Open();

string conStr = "Host=10.0.1.1;Port=1521;User ID=scott;Password=tiger; Service Name=ORCL;Alternate Servers=(Host=10.0.1.2;Port=1521;Service Name=ORCL)";

使用上，与OracleClient基本相同，但在OracleCommand的Parameter定义和使用上略有不同，如下：

 

OracleClient:

 OracleCommand mCmd = new OracleCommand("insert into " + sTable + "(test1,test2) values('111',:mBlob)", mCon);
 mCmd.Parameters.Add("mBlob", OracleType.Blob, blob.Length).Value = blob;
return mCmd.ExecuteNonQuery();

OracleCommand mCmd = new OracleCommand("insert into " + sTable + "(test1,test2) values('111',:mBlob)", mCon); mCmd.Parameters.Add("mBlob", OracleType.Blob, blob.Length).Value = blob; return mCmd.ExecuteNonQuery();

 

 

ddtek

OracleCommand mCmd = new OracleCommand("insert into " + sTable + "(test1,test2) values('111',?)", mCon);
mCmd.BindByName = true;
mCmd.Parameters.Add(":mBlob", OracleDbType.Blob, blob.Length).Value = blob;
return mCmd.ExecuteNonQuery();

OracleCommand mCmd = new OracleCommand("insert into " + sTable + "(test1,test2) values('111',?)", mCon); mCmd.BindByName = true; mCmd.Parameters.Add(":mBlob", OracleDbType.Blob, blob.Length).Value = blob; return mCmd.ExecuteNonQuery();  

 

 

DDTEK里，SQL语句中使用？代替变量，下边按照Parameters数组中的顺序依次赋值
