有的时候我们需要在ADO.NET中同时执行多条的SQL语法,我们要如何处理,

例如下:

        //查詢基本資料
private static void TestQry()
{
DataTable dtReturn =new DataTable();
//查詢基礎資料
try
{
//模擬查詢原始資料
string strSql1 = @"
Select id,name from databasename@dblinkname:tablename
union
Select id,name from databasename@dblinkname:tablename
into temp tmp_tablename with no log;
";
string strSql2 = @"
select * from tmp_tablename;
";
string strSql3 = @"
drop table tmp_tablename;
";
using (IfxConnection conn = new IfxConnection(gsConnStr))
{
using (IfxCommand cmd = new IfxCommand(strSql1, conn))
{
conn.Open(); //
cmd.CommandType = CommandType.Text;
cmd.CommandText = strSql1;
cmd.ExecuteNonQuery(); using (IfxDataAdapter ad = new IfxDataAdapter(strSql2, conn))
{
ad.Fill(dtReturn);
} cmd.CommandType = CommandType.Text;
cmd.CommandText = strSql3;
cmd.ExecuteNonQuery(); conn.Close();
}
}
}
catch (Exception ex)
{
dtReturn = null;
Console.WriteLine(ex.Message);
}
}
