Sqlit3不接受空格中輸入

Question

我在sqlite3的數據庫中的表徑（即處理自行車道，其模式是：

CREATE TABLE trails (ID integer primary key, name text, city text, state char(2), length integer, ascent integer, difficulty char(2), description text); 

然後我嘗試插入值是：

INSERT INTO trails (name, city, state, length, ascent, difficulty, description) VALUES (‘Blue'Sky’,‘Fort Collins’,‘CO’, 6, 300, ‘bg’, ‘cool trail’); 

我認爲，數據類型的文本將採取給予任何形式的字符串（甚至那些字符串，例如一個段落）。這是怎麼回事了？

Answer 1

字符串的字符可以是單引號'或雙引號"。當字符串包含單引號時使用雙引號。

CREATE TABLE trails (ID integer primary key, name text, city text, state char(2), length integer, ascent integer, difficulty char(2), description text); 

INSERT INTO trails (name, city, state, length, ascent, difficulty, description) VALUES ("Blue'Sky","Fort Collins","CO", 6, 300, "bg", "cool trail");
