I have created a Google cloud mySql instance that I would like to use to store some greenhouse information. I have set up the instance and I have also connected my NodeJs program to the instance. I also have the mysql cloud proxy running with the following command
.\cloud_sql_proxy.exe -instances=my-instance-name=tcp:3306
The following code was used to connect to the database.
var dbConnected = false;
const config = ConnectionOptions = {
host: '127.0.0.1',
user: 'Username',
password: 'Password',
database: 'GreehouseInfo',
dialect: 'mysql',
synchronize: true,
}
const connection = mysql.createConnection(config);
async function ConnectToDatabse() {
await connection.connect((err) => {
if (err) throw err;
console.log('Connected!');
dbConnected = true;
});
}
Now I have also used the following query to Create some of my Tables dynamically and the code looks something like this #
async function CreateTables() {
return new Promise(resolve => {
if (dbConnected){
var sql = "CREATE TABLE IF NOT EXISTS Users(User_ID INT AUTO_INCREMENT PRIMARY KEY,UserName VARCHAR(255) NOT NULL,Password VARCHAR(255))";
connection.query(sql, function (err, result) {
console.log(result)
if (err) console.log(err);
});
}
console.log("Table created");
resolve();
});
}
The query does not throw any errors when I start the node service and says that the tables were created and when I connect to the DB Instance using the command line and the following command mysql -u RichardTeunen -p --host 127.0.0.1 --port 3306 then I can use the following command show tables; To see my tables and then I can see the table users that I have just created
The issue i am experiencing is when I try to perform any queries on the table. I have created the following function for performing queries for me.
async function PerformQuery(querytext) {
return new Promise(resolve => {
if (dbConnected){
var sql = querytext;
connection.query(sql, function (err, result) {
if (err) console.log(err.message);
});
}
console.log("Query performed");
resolve();
});
}
I have tried Select and Insert statements with this query and I always get the error that
The table GreehouseInfo.USERS does not exist
However as I just showed the Table does exist, so I am unsure why this is occurring. I have read that this happens if you backup your device to another location and then you should take some files with you but I am unsure what database files I may have to copy to my local device to make the connection valid on this device. Any advice would be much appreciated.
