Question

我在mysql的一个简单案例中陷入困境。我不知道如何用另一个变量名编写变量。

@a='hello'
@hello='yes'
how can we get the value of @(@a) as 'yes' ;

我的情况：

我尝试在mysql中导入一个txt文件，但该列是动态的。

txt Ex

COL1 COL2 COL3 COL4 COL5 COL6 COL7 COL8 COL9 COL10 COL11 COL12....
1    a    b     1    c    d
2    a1   a2    b1   b2   3   c1   c2   c3   d1     d2    d3
.....

字母列是动态的，取决于数字值列（1或2或3）

我想要做的是将这些数据插入到mysql的表中

我的解决方案是将动态部分作为数组处理并将其放在表的一列中：

Number1      A       B        Number2    C               D
2            a1 a2   b1 b2    3          c1 c2 c3        d1 d2 d3

我的sql命令：

LOAD DATA INFILE 'txt' INTO TABLE test FIELDS TERMINATED BY '|' OPTIONALLY ENCLOSED BY '\"' LINES TERMINATED BY '\\n' (@col1,@col2,@col3,@col4,@col5,@col6,@col7,@col8,@col9,@col10,@col11,@col12,@col13,@col14,@col15,@col16,@col17,@col18,@col19,@col20) 

set Number1=@col1,

set A=(CASE @col1 WHEN '1' THEN @col2 WHEN '2' THEN CONCAT(@col2,',',@col3) WHEN '3' THEN CONCAT(@col2,',',@col3,',' ,@col4) END)

set B=(CASE @col1 WHEN '1' THEN @col3 WHEN '2' THEN CONCAT(@col4,',',@col5) WHEN '3' THEN CONCAT(@col5,',',@col6,',' ,@col7) END)"

set C ?

我想这样做：

set c=@col(1+@col1+@col1)

因为如果我使用案例，我应该写这么多次，而对于下一列C，我应该写一下col1和第NUMBER2列的值的组合

提前感谢您的帮助

因为iam在这一点上大胆，所以我花了一天时间写了一个长度为31662的sql 你甚至无法用手绘制所有这些内容：

sql = "LOAD DATA INFILE %s INTO TABLE cdr_data_test_1 FIELDS TERMINATED BY '|' OPTIONALLY ENCLOSED BY '\"' LINES TERMINATED BY '\\n'
