I selected a table in mysql workbench by running a query like:
select * from table1
From the results grid I made some updates to the result. However, when I run the query again non of my updates are there anymore?
Is it possible to add or edit result from MySQL Workbench?
after edit the row press on apply Then apply the script on the DataBase

I've written code to insert data in mysql database successfully compiled it on cmd and my database along with table is also ready.
I want to know the further steps so that can understand whether my record has inserted or not in mysql
If your code is doing as expected, and there is no error, then the values should be inserted.
Steps to check whether everything is working fine or not:
Go to your database and run this query:
SELECT * FROM tableName
Run the program and insert some data.
Again go to your database and run this query:
SELECT * FROM tableName
If there are changes appeared according to the data inserted, it means your program is working fine.
I'm not that good at mysql but some of my tables has this line where I can edit and delete the row easy without writing any SQL? How can I make that row inside another table?
You can use any GUI editor like phpmyadmin or the tools which P.Salmon mentioned.
Using GUI editor, you can connect to the database using connection string and you can view tables and see the result which can edited and deleted.
I am using MySQL Query Browser 1.2.17. My problem is that using EXACTLY the same query sometimes I get No database selected error.
I tried to find any dependence in using USE database; or FROM database.table.
I have no idea when will I get an error and when I won't and if I get I don't know how to solve this (since there is in the query USE database;).
UPDATE AND SOLUTION:
Since the problem was independent neither on the USE database; nor FROM database.table and has been observed RANDOMLY (ex. run query, it works, then immediately run again with the same query and it didn't work anymore), I recreated the database simply filling it with data from backup and it helped.
Best practice to write query.
databasename.tablename
example
SELECT * FROM database.table where 1 = 1
I managed to connect to MySQL DB via Sql Developer following this guide. MySQL DB shows and I can expolre tables via the navigator. However, I could not run SELECT statement to show any of these tables. In MySQL workbench I used to use :
use [database_name]
Then, run select statement in that database. But in Sql developer, I am not sure what should I add to the statement to make it work. I have tried the following:
select *
from [table_name].[database_name];
It does not work. I found this tutorial, but nothing is mentioned about simple select statement. Any help is deeply appreciated.
AFAIK, except MySQL specific commands; all other standard SQL commands like SELECT,INSERT,UPDATE,DELETE should work just fine using SQL Developer. but per your posted query, it looks total strange.
Your query
select * from [table_name]#[database_name];
remove that # sign.
you should qualify like database_name.table_name.
Unless it's a typo, remove those [] as well from your query
statement.
Your query should look like
select * from database_name.table_name;
You can always write your SQL including database as well, in the form of:
database.tablename
such as:
select * from wordpressdb.usertable where username="someone"
Suppose that I want to execute two query one is-
select * from table1;
select * from table2;
if I want to execute it I need to remove one query from two then I can execute, I'm using mysql query browser1.2.12.
If we use script tab then I can not see the output, is there any way to execute one of query from multiple query after selection.
that functionality is not available in mysql query browser on any version.
Mysql Query Browser is getting old nowdays. Mysql launch the new generation IDE with name Mysql Workbench.
use it,here u got more options.
enjoy!!
