sqlite：多个where子句语法：where s="somestring" and where i=0;

Question

我犯了什么错误？

$ sqlite3 test.db
SQLite version 3.8.5 2014-08-15 22:37:57
Enter ".help" for usage hints.
sqlite> create table t (s text not null, i integer);
sqlite> select * from t where s="somestring"; /* works */;
sqlite> select * from t where i=0; /* works */;
sqlite> select * from t where s="somestring" and where i=0;
Error: near "where": syntax error

Answer 1

尝试

select * 
from t 
where s="somestring" 
and i=0;

而不是

select * 
from t 
where s="somestring" 
and where i=0;

Answer 2

select * from t where s="somestring" and i=0;

删除最后一个 where - 每个语句只需要而且只能有一个 where。

Answer 3

您不需要在此查询中指定 where 2 次

sqlite> select * from t where s="somestring" and i=0;

应该够了。

sqlite：多个where子句语法：where s="somestring" and where i=0;

sqlite: multiple where clause syntax: where s="somestring" and where i=0;
