I was wondering if there is a way to retrieve the MySQL code for DB setup. Right now it's using sqlite for output when I run 'manage.py sql management'
See below:
MB-PR0:users jg$ python manage.py sql management
BEGIN;
CREATE TABLE "management_service" (
"id" integer NOT NULL PRIMARY KEY,
"service_name" varchar(32) NOT NULL
)
;
CREATE TABLE "management_employee_services" (
"id" integer NOT NULL PRIMARY KEY,
"employee_id" integer NOT NULL,
"service_id" integer NOT NULL REFERENCES "management_service" ("id"),
UNIQUE ("employee_id", "service_id")
)
;
CREATE TABLE "management_employee" (
"id" integer NOT NULL PRIMARY KEY,
"first_name" varchar(32) NOT NULL,
"last_name" varchar(32) NOT NULL,
"email" varchar(32) NOT NULL,
"gmail_active" bool NOT NULL,
"employee_status" bool NOT NULL
)
;
CREATE TABLE "management_note" (
"id" integer NOT NULL PRIMARY KEY,
"note_name" text NOT NULL,
"employee_id" integer NOT NULL REFERENCES "management_employee" ("id")
)
;
COMMIT;
Is there a way to have this output as MySQL?
Thanks!
Change your settings.py file to use
MySQL
run manage.py sql management
Change your Settings.py file back.
I think that should work. I've never tried it though.
This looks like basic SQL syntax. Can't you use this script by just running it via commandline?
$ mysql <my_db_name> -u<user_name> -p < mysql.sql
(This is using commandline redirecting)
You will be asked for your password after pressing enter, then the script is executed.
Before that you can check if it is installed:
$ mysql -V
..or do you have phpmyadmin or the MySQL "IDE" installed? At least from the last one you could execute the script from a GUI desktop application, if needed.

I try do create a simple mysql database with Flyway migration, but it doesn't going well.
I have created my .sql it named as V1_0__init.sql and I've written some sql commands there:
CREATE TABLE User (
id INT PRIMARY KEY AUTO_INCREMENT NOT NULL,
created DATE NOT NULL,
username varchar(15) NOT NULL,
password varchar(15) NOT NULL,
email varchar(40) NOT NULL,
status boolean NOT NULL,
unique(username)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
I think it should be fine, but I have two errors, one at the first line (CREATE TABLE) and another at the fourth line (created DATE NOT NULL).
The error message says:
Invalid or Incomplete statement
Expected one of the following: ALGORITHM DEFINER SQL VIEW
(At the 'created DATE NOT NULL' line have a similar message, the only difference is this: Algoritm definer OR sql view)
I've tried to fix these but it didn't go well.
Anyone could help me how to fix this?
Maybe did I miss something? Should I do something in application.properties?
I need this code to run the instant the professor hits the F5 button.
I created a database and I have a problem with the USE statement
SQL just can't switch to the database that USE statement is calling. it's saying this:
could not locate entry in sysdatabases for database
I tried with square brackets ([]) and it's not helping.
The project is about Car Service and its a school project.
I just need that USE statement to run or some other solution so the code can run without error and in one click on F5.
USE master;
IF DB_ID('ServisAutomobila') IS NOT NULL
DROP DATABASE ServisAutomobila;
GO
CREATE DATABASE ServisAutomobila;
USE ServisAutomobila
go
CREATE TABLE Automobil
(
Automobil_ID int identity (1,1) not null,
Model nvarchar (50) not null,
GodinaProizvodnje nvarchar(50) not null,
RegistarskiBroj nvarchar (50) unique not null,
BrojMotora nvarchar (50) unique not null,
BrojSasije nvarchar (50) unique not null,
Kvar nvarchar (250) not null,
TipAutomobila_ID int not null,
Zemlja_ID int not null,
Vlasnik_ID int not null
)
CREATE TABLE Zemlja
(
Zemlja_ID int identity (1,1) not null,
Zemlja nvarchar (50) not null
)
The GO keyword is a batch terminator. So in your example:
CREATE DATABASE ServisAutomobila;
USE ServisAutomobila
go
The batch is executed as one and results in that particular error because the database engine tries do use database ServisAutomobila which does not exists yet. This means that you must add that extra GO suggested in the previous comments before you can use the newly created database:
CREATE DATABASE ServisAutomobila;
GO;
USE ServisAutomobila;
GO;
I am trying to create database android_api and table users but I am getting error
#1064 - Something is wrong in your syntax near 'use android_api
create table 'users'(
id int(11) NOT NULL primary KEY AU' w linii 3
Here is the code
create database android_api
use android_api
create table users(
id int(11) NOT NULL primary KEY AUTO_INCREMENT,
unique_id varchar(23) not null unique,
name varchar(50) not null,
email varchar(100) not null unique,
encrypted_password varchar(80) not null,
salt varchar(10) not null,
created_at datetime,
updated_at datetime null
);
You should separate each SQL statement with ;, otherwise your syntax is incorrect.
Here is the correct syntax:
create database android_api;
use android_api;
create table users(
id int(11) NOT NULL primary KEY AUTO_INCREMENT,
unique_id varchar(23) not null unique,
name varchar(50) not null,
email varchar(100) not null unique,
encrypted_password varchar(80) not null,
salt varchar(10) not null,
created_at datetime,
updated_at datetime null
);
In your code what you did was actually:
create database android_api use android_api
(Which is not a valid CREATE statement).
Actually, the accepted answer is enough. This is a very small idea to share after running into the same problem as you report it, but in a beginner's tutorial Load PostgreSQL Sample Database in an SQL Shell.
In general, if you have the reported error in an SQL shell, and if you are not sure whether you have typed ; at the end of the last line, just type ; as a new command and press Enter to be sure that you type your next command in LINE 1 and not in LINE 2.
Without this "trick", some stupidity like this can happen:
postgres=# CREATE DATABASE dvdrental
postgres-# show databases
postgres-# create database dvdrental;
ERROR: syntax error at or near »show«
LINE 2: show databases
^
postgres=# create database dvdrental
postgres-# CREATE DATABASE dvdrental;
ERROR: syntax error at or near »CREATE«
LINE 2: CREATE DATABASE dvdrental;
^
postgres=# CREATE DATABASE dvdrental;
CREATE DATABASE
Finally working, as can be seen by the output CREATE DATABASE.
I am currently using mysql as my database and use flyway to manage database schema. All my unit tests are running against mysql and they are running really slow with adding more unit tests. Now I want to change the database from mysql to h2 memory database in unit tests. Below is my setting for h2 db connection:
#Datasource
spring.datasource.url=jdbc:h2:mem:testDb;MVCC=TRUE;LOCK_TIMEOUT=10000;DB_CLOSE_ON_EXIT=FALSE;DATABASE_TO_UPPER=true
spring.datasource.username=
spring.datasource.password=
spring.datasource.driver-class-name=org.h2.Driver
spring.datasource.default-transaction-isolation-level=1
When I run flywayMigrate, I got some sql errors. Below is one example, this sql is used to create a table on mysql but failed to run on h2.
CREATE TABLE `file_storage` (
`id` BIGINT(64) NOT NULL AUTO_INCREMENT,
`file_name` VARCHAR(45) NULL,
PRIMARY KEY (`id`))
DEFAULT CHARACTER SET = utf8;
below is the error I got from h2. I don't know what wrong with my sql. Is there a way for h2 to accept mysql database schema?
Execution failed for task ':dbschema:flywayMigrate'.

I have hundreds of sql scripts which is running fine in mysql. So I don't want to change anything in these scripts. Is there a way to allow h2 accepts mysql script?
According to this description, you may try to use your H2 database in MySQL Compatibility Mode, by setting it in the connection string as MODE=MySQL. Here is exactly what is said about it:
To use the MySQL mode, use the database URL jdbc:h2:~/test;MODE=MySQL or the SQL statement SET MODE MySQL.
When inserting data, if a column is defined to be NOT NULL and NULL is inserted, then a 0 (or empty string, or the current timestamp for timestamp columns) value is used. Usually, this operation is not allowed and an exception is thrown.
Creating indexes in the CREATE TABLE statement is allowed using INDEX(..) or KEY(..). Example: create table test(id int primary key, name varchar(255), key idx_name(name));
Meta data calls return identifiers in lower case.
When converting a floating point number to an integer, the fractional digits are not truncated, but the value is rounded.
Concatenating NULL with another value results in the other value.
Text comparison in MySQL is case insensitive by default, while in H2 it is case sensitive (as in most other databases). H2 does support case insensitive text comparison, but it needs to be set separately, using SET IGNORECASE TRUE. This affects comparison using =, LIKE, REGEXP.
Your issue can be seen with your example
CREATE TABLE `file_storage`
(
'id` BIGINT(64) NOT NULL AUTO_INCREMENT,
`file_name` VARCHAR(45) NULL,
PRIMARY KEY (`id`)
)
DEFAULT CHARACTER SET = utf8;
The last line "DEFAULT CHARACTER SET = utf8" is setting a mySQL table option. H2 does not have such an option at either the table or schema level as it operates using Unicode at all times.
If you have a lot of SQL DDL statements that have been written over the years for MySQL you are likely to see a lot of such issues.
I have this #1007 error with my SQL code. When I try to import into my database it gives me this #1007 error. The data base is called company. I'm new to SQL and it would be good if someone could help me out. Thanks
CREATE DATABASE company;
CREATE TABLE login(
id int(10) NOT NULL AUTO_INCREMENT,
username varchar(255) NOT NULL,
password varchar(255) NOT NULL,
PRIMARY KEY (id)
)
It looks like the database "company" may already exist. If you look at the link provided by #Marc B, the error "#1007" corresponds to:
"Error: 1007 SQLSTATE: HY000 (ER_DB_CREATE_EXISTS)
Message: Can't create database '%s'; database exists
An attempt to create a database failed because the database already exists.
Drop the database first if you really want to replace an existing database, or add an IF NOT EXISTS clause to the CREATE DATABASE statement if to retain an existing database without having the statement produce an error."
Check your schema to make sure that you don't already have a database called "company" created.
Perhaps you are only trying to create the table "login", whereas you would simply need the code:
CREATE TABLE login(
id int(10) NOT NULL AUTO_INCREMENT,
username varchar(255) NOT NULL,
password varchar(255) NOT NULL,
PRIMARY KEY (id)
)
making sure you create this table in the already existing "company" database.
You are trying to create a database that has already been created.
Staring at your two commands, you could do CREATE TABLE IF NOT EXISTS
you also need to set default database before creating the table
CREATE DATABASE IF NOT EXISTS company;
USE company
CREATE TABLE login (
id int NOT NULL AUTO_INCREMENT,
username varchar(255) NOT NULL,
password varchar(255) NOT NULL,
PRIMARY KEY (id)
);
or you could put the DB name before the table name
CREATE DATABASE IF NOT EXISTS company;
CREATE TABLE company.login (
id int NOT NULL AUTO_INCREMENT,
username varchar(255) NOT NULL,
password varchar(255) NOT NULL,
PRIMARY KEY (id)
);
