Question

我有

CmdString = "insert into Team_table (name1, name2, result1, result2) (select t1.name,t2.name,NULL,NULL from teams t2 cross join teams t1)";

当按下输入时将其分为2列，如

CmdString = "insert into Team_table (name1, name2, result1, result2) 
(select t1.name,t2.name,NULL,NULL from teams t2 cross join teams t1)";

错误出现

我该如何解决？

Answer 1

尝试以下

CmdString = "insert into Team_table (name1, name2, result1, result2)" + 
" (select t1.name,t2.name,NULL,NULL from teams t2 cross join teams t1)";

或

CmdString = @"insert into Team_table (name1, name2, result1, result2) 
(select t1.name,t2.name,NULL,NULL from teams t2 cross join teams t1)";

Answer 2

在字符串前面使用@符号，然后可以在多行上打破字符串

string CmdString = @"insert into Team_table (name1, name2, result1, result2) 
                (select t1.name,t2.name,NULL,NULL from teams t2 cross join teams t1)";

您收到错误的原因是因为编译器将新行视为新的C＃语句，并且它期望您关闭前一个字符串并使用;

终止语句编辑：正如@Servy指出的那样，将其作为逐字字符串（带@）会导致新行字符成为字符串的一部分。所以你的字符串将是这样的：

"insert into Team_table (name1, name2, result1, result2) \r\n (select t1.name,t2.name,NULL,NULL from teams t2 cross join teams t1)"

如果你不想换行并希望在多行上拆分字符串，那么你必须在每一行上定义一个字符串并使用如下的连接：

string CmdString = 
    "insert into Team_table (name1, name2, result1, result2) " + 
    "(select t1.name,t2.name,NULL,NULL from teams t2 cross join teams t1)";

Answer 3

喜欢这个。

    CmdString = "insert into Team_table (name1, name2, result1, result2)" + 
        "(select t1.name,t2.name,NULL,NULL from teams t2 cross join teams t1)";
