Question

我有这样的查询。

SELECT * FROM player_details where name in ('messi','neymar','suarez','alves')

我想在钛中执行此查询。我试过这个

var in  = ['messi','neymar','suarez','alves'];
db.execute('SELECT * FROM player_details where name in ?',in);

但上面的代码产生错误。如何在钛中添加IN和NOT IN条件？

Answer 1

单个参数?替换单个表达式。

如果有四个值，则需要四个参数：

db.execute('SELECT * FROM player_details where name in (?,?,?,?)', in);

Answer 2

如果数组的长度是动态的，请尝试以下方法：

var params = ["messi", "neymar", "suarez", "alves"],
    qMarks = new Array(params.length).join("?,") + "?";


db.execute("SELECT * FROM player_details WHERE name in (" + qMarks + ");", params);

如何在查询参数中使用IN？
