javascript - SQLite "The given key was not present in the dictionary"

Question

我有使用 sql lite 插件的 cordova windows 应用程序。现在看到两个查询执行相同的操作:

1) "CREATE TABLE IF NOT EXISTS Settings (setting TEXT PRIMARY KEY, value TEXT NOT NULL)";
2) "CREATE TABLE IF NOT EXISTS Settings (setting TEXT, value TEXT NOT NULL, PRIMARY KEY(setting))";

不幸的是，第二个将会失败

"PRAGMA foreign_keys = ON";

不幸的是，我的表具有多列的主键，因此需要第二种语法。

example: PRIMARY KEY(setting, value)

知道为什么以及如何解决吗？

代码:

let db = window.openDatabase("MFS", "", "MFS database", 52428800);
db.transaction((tx) => {
    let query1 = "CREATE TABLE IF NOT EXISTS Settings (setting TEXT PRIMARY KEY, value TEXT NOT NULL)",
        query2 = "CREATE TABLE IF NOT EXISTS Settings (setting TEXT, value TEXT NOT NULL, PRIMARY KEY(setting))";
    tx.executeSql(query1/*query2*/, [], (tx, result, query) => {
    }, (tx, err, query) => {
        alert(err.message);
    }
});

Answer 1

我使用CREATE TABLE IF NOT EXISTS Settings(设置INTEGER PRIMARY KEY ...)定义主键，它的工作方式就像一个魅力:

db.transaction(createLocalTableSettings, errorLocalTable, successCreateLocalTableSettings);

function createLocalTableSettings(tx) {
    tx.executeSql('CREATE TABLE IF NOT EXISTS Settings (setting INTEGER PRIMARY KEY, value TEXT NOT NULL)');
}
function successCreateLocalTableSettings() {
        console.log('Settings Table successful created');
}
function errorLocalTable(err) {
        console.log("Error creating Settings Table! Processing SQL: " + err.sql + " Parameter: " + JSON.stringify(err.params));
}

希望这有帮助!
