[英]Swift FMDB modifiers
where are the modifiers for SQL FMDB described ? SQL FMDB的修饰符在哪里描述? In particular, how do I place a quote within a string I wish to insert.
特别是,如何在要插入的字符串中放置引号。 Such as I wish to insert name "Mac's Place" into the database ?
例如我希望在数据库中插入名称“ Mac's Place”? thanks
谢谢
If you use executeUpdate
with ?
如果将
executeUpdate
与?
placeholders in the SQL and then supply the parameters as arguments in the array, you don't have to quote the special characters in the string. SQL中的占位符,然后将参数作为数组中的参数提供,您不必在字符串中引用特殊字符。 For example, you can:
例如,您可以:
if !db.executeUpdate("insert into restaurants (name) values (?)", withArgumentsInArray: ["Mac's Place"]) {
println(db.lastErrorMessage())
}
