我正在使用 SQLite.swift。
有什么方法可以在 SQLite 中执行不区分变音符号的 LIKE 查询?例如,这个查询:
SELECT * FROM users WHERE name LIKE "thu%"
会返回:
thử
thu
thư
etc.

来自 the documentation :
We can create custom collating sequences by calling createCollation on a database connection.
try db.createCollation("NODIACRITIC") { lhs, rhs in
return lhs.compare(rhs, options: .DiacriticInsensitiveSearch)
}
We can reference a custom collation using the Custom member of the Collation enumeration.
restaurants.order(collate(.Custom("NODIACRITIC"), name))
// SELECT * FROM "restaurants" ORDER BY "name" COLLATE "NODIACRITIC"
在您的情况下,您可以在之后执行以下查询:
SELECT * FROM users WHERE name COLLATE NODIACRITIC LIKE 'thu%'
