如何在一个查询中传递多个命令？

Question

大家好我怎样才能更简单地编写下面的代码？ ...在一个查询中有两个sql（OleDb）命令。

con.open();
cmd.CommandText = "DELETE * FROM Customers WHERE ID_C = 1";
cmd.ExecuteNonQuery();
cmd.Clone();
cmd.CommandText = "DELETE * FROM Books WHERE ID_B = 1";
cmd.ExecuteNonQuery();
cmd.Clone();
con.close();

Answer 1

如果您不需要受影响的行数（由ExecuteNonQuery返回），您只需将两个命令放在以“;”分隔的同一SQL中

con.open();
cmd.CommandText = "DELETE * FROM Customers WHERE ID_C = 1; DELETE * FROM Books WHERE ID_B = 1";
cmd.ExecuteNonQuery();
con.close();
