这是我的密码:
db = SQLite.openDatabase(database_name, database_version, database_displayname, database_size, this.openCB, this.errorCB);
db.transaction((tx) => {
tx.executeSql('CREATE TABLE IF NOT EXISTS Inspections( '
+ 'id INTEGER PRIMARY KEY NOT NULL, '
+ 'inspector_id INTEGER NOT NULL, '
+ 'inspection_data TEXT ); ', [], this.successCB, this.errorCB);
tx.executeSql('INSERT INTO Inspections (inspector_id, inspection_data) VALUES ('+decoded.uid+','+formData+');', []);
});
我想在检查表中插入json数据。我还使用了json.strigify()函数,但没有得到任何解决方案。尝试以下方法:
db = SQLite.openDatabase(database_name, database_version, database_displayname, database_size, this.openCB, this.errorCB);
db.transaction((tx) => {
tx.executeSql('CREATE TABLE IF NOT EXISTS Inspections( '
+ 'id INTEGER PRIMARY KEY NOT NULL, '
+ 'inspector_id INTEGER NOT NULL, '
+ 'inspection_data TEXT ); ', [], this.successCB, this.errorCB);
tx.executeSql('INSERT INTO Inspections (inspector_id, inspection_data) VALUES (?,?);', [decoded.uid,formData]);
});
