我定义我的表并导入数据…

> .separator "\t"
> .headers on
> CREATE TABLE clinical(
       patid      VARCHAR(20),eventdate  CHAR(10),sysdate    CHAR(10),constype   INT,consid     INT,medcode    INT,staffid    VARCHAR(20),textid     INT,episode    INT,enttype    INT,adid           INT);
> .import "Sample_Clinical001.txt" clinical
> SELECT * FROM clinical LIMIT 10;
patid   eventdate   sysdate constype    consid  medcode staffid textid  episode enttype adid
patid   eventdate   sysdate constype    consid  medcode staffid textid  episode enttype adid
471001  30/01/1997  09/03/1997  4   68093   180 0   0   0   20  11484
471001  30/01/1997  09/03/1997  2   68093   60  0   0   0   4   11485

我的第一个想法是删除违规行,但是没有按预期的方式工作,而是删除整个表…

> DELETE FROM clinical WHERE patid = "patid";
> SELECT * FROM clinical LIMIT 3;
>

我是否得到测试平等错误的语法？我不确定; the docs似乎不区分两者.我以为我会再试一次

> .import "Sample_Clinical001.txt" clinical
> SELECT * FROM clinical LIMIT 3;
patid   eventdate   sysdate constype    consid  medcode staffid textid  episode enttype adid
patid   eventdate   sysdate constype    consid  medcode staffid textid  episode enttype adid
471001  30/01/1997  09/03/1997  4   68093   180 0   0   0   20  11484
471001  30/01/1997  09/03/1997  2   68093   60  0   0   0   4   11485
> DELETE FROM clinical WHERE patid == "patid";
> SELECT * FROM clinical LIMIT 3;
>

我甚至在这里正确的轨道上,还是我做一些愚蠢的事情？

我会期望在调用.import时跳过标题行是一个简单的选项,因为在文本文件中具有标题行是一个相当常见的情况.
