Of date and time data types Data type Name Format DATE YYYY-MM-DD DATETIME YYYY-MM-DD HH:MM:SS TIMESTAMP YYYYMMDDHHMMSS TIME HH:MM:SS Table constraints You can use any of the following table constraints.NOT NULL: Ensures that the value of the column must not be nullCHECK: Before inserting data in the table, it evaluates the condition specified in the CHECK constraint. If the condition fails, then the insert statement failsDEFAULT: Default values of the column. If you do not specify the value of the column in the insert statement, the query inserts the value specified in the DEFAULT constraintPrimary and Foreign keys Once columns are defined, you can create primary key and foreign keys using the following keywordsPRIMARY KEY: It’s a unique index and must be defined as NOT NULL. A table can have only one primary key. The PRIMARY KEY is placed first in the create table statementFOREIGN KEY: MySQL supports the foreign keys. A table can have more than one foreign key that references the primary key of different tablesMySQL Create Table example If you want to create a table using MySQL Workbench, you must configure a new connection. To do that, open MySQL workbench, and on the Welcome screen, click on “MySQL connections.” See the following image: In “Setup New Connection” dialog box, provide the desired name of the connection, Hostname or IP Address of the MySQL database server, port, user name, and password and click on OK. See the following image: Execute the following query to create a new table named “tblEmployees” in the “Employees” database. CREATE TABLE `employees`.`tblemployee` ( `Employee_ID` INT NOT NULL AUTO_INCREMENT, `Employee_Name` VARCHAR(45) NOT NULL, `Employee_Department_ID` INT NOT NULL, `Employee_Grade_ID` INT NOT NULL DEFAULT A, `Employee_Salary` INT NOT NULL, PRIMARY KEY (`Employee_ID`), INDEX `FK_Department_ID_idx` (`Employee_Department_ID` ASC) VISIBLE, CONSTRAINT `FK_Department_ID` FOREIGN KEY (`Employee_Department_ID`) REFERENCES ` employees`.`department` (`Department_ID`)

Chapter 33 MySQL Workbench MySQL Workbench provides a graphical tool for working with MySQL servers and databases. MySQL Workbench is developed and tested with MySQL Server 8.0. MySQL Workbench may connect to MySQL Server 8.4 and higher but some MySQL Workbench features may not function with those newer server versions. The following discussion briefly describes MySQL Workbench capabilities. For more information, see the MySQL Workbench manual, available at MySQL Workbench provides five main areas of functionality: SQL Development: Enables you to create and manage connections to database servers. As well as enabling you to configure connection parameters, MySQL Workbench provides the capability to execute SQL queries on the database connections using the built-in SQL Editor. This functionality replaces that previously provided by the Query Browser standalone application. Data Modeling: Enables you to create models of your database schema graphically, reverse and forward engineer between a schema and a live database, and edit all aspects of your database using the comprehensive Table Editor. The Table Editor provides easy-to-use facilities for editing Tables, Columns, Indexes, Triggers, Partitioning, Options, Inserts and Privileges, Routines and Views. Server Administration: Enables you to create and administer server instances. Data Migration: Allows you to migrate from Microsoft SQL Server, Sybase ASE, SQLite, SQL Anywhere, PostreSQL, and other RDBMS tables, objects and data to MySQL. Migration also supports migrating from earlier versions of MySQL to the latest releases. MySQL Enterprise Support: Support for Enterprise products such as MySQL Enterprise Backup and MySQL Audit. MySQL Workbench is available in two editions, the Community Edition and the Commercial Edition. The Community Edition is available free of charge. The Commercial Edition provides additional Enterprise features, such as database documentation generation, at low cost.. Setting up foreign key in Mysql Workbench. 0. Can't create Foreign Key. 2.

And the consequences of the seemingly simple changes can be disastrous. Ensuring that all references to the renamed table reflect its new name can take much time and effort. With the help of dbForge Refactoring tool, you can quickly and easily rename database tables, including the temporary ones, and the tool will automatically correct all references to the renamed objects. Renaming MySQL schemas MySQL Server doesn't support schema renaming. The RENAME DATABASE statement was added in MySQL 5.1.7 but then was found to be dangerous and was removed in MySQL 5.1.23. To safely rename a database schema, you can use the following tools that come with dbForge Studio for MySQL: Backup/Restore Schema/Data Compare Copy Database The choice of a tool depends on your goals and project requirements. Renaming columns referenced by other columns using foreign keys When renaming a column, you always need to worry about references that use foreign keys - if you manually rename a column, these dependencies will be lost or you will have to find all foreign keys,

Re: How to export if I have foreign keys? Hi!(Donno whether this procedure is advisible or not..but I used tis before for my stuff & worked fine for me..){FromDocs]To make it easier to reload dump files for tables that have foreign key relationships, mysqldump automatically includes a statement in the dump output to set FOREIGN_KEY_CHECKS to 0 as of MySQL 4.1.1. This avoids problems with tables having to be reloaded in a particular order when the dump is reloaded. For earlier versions, you can disable the variable manually within mysql when loading the dump file like this: mysql> SET FOREIGN_KEY_CHECKS = 0;mysql> SOURCE dump_file_nameor simplymysql db_name mysql> SET FOREIGN_KEY_CHECKS = 1;This allows you to import the tables in any order if the dump file contains tables that are not correctly ordered for foreign keys. It also speeds up the import operation. FOREIGN_KEY_CHECKS is available starting from MySQL 3.23.52 and 4.0.3. Setting FOREIGN_KEY_CHECKS to 0 can also be useful for ignoring foreign key constraints during LOAD DATA or ALTER TABLE operations. Hope this helps!Regards,Umesh Shastry Subject Written By Posted Re: How to export if I have foreign keys? May 13, 2005 06:17AM Sorry, you can't reply to this topic. It has been closed.

ON DELETE RESTRICT ON UPDATE CASCADE); Following are the details of the columns: The ID of the Employee is saved in the employee_id column. It is a primary key of the table and has an auto-increment column; hence you do not have to specify the value for this column explicitly. When you insert the data in the table, MySQL generates a sequential integer for the employee_id column The Name of the employee is saved in the employee_name column. The data type of the column is varchar(), and the length is 45. You cannot insert a NULL value in the employee_name column The department ID of the employee is saved in the employee_department_id column. The data type of this column is INTEGER. It’s a foreign key column that references the department_id column of the tbldepartment table. If any row is updated in the tbldepartment table, the values in tblemployee updates automatically (ON UPDATE CASCADE), and the delete operation on the tbldepartment is restricted (ON DELETE RESTRICT) The grade of the employee is saved in the employee_garde column. The data type of this column is varchar and length is 2. The DEFAULT constraint has been created on this column. If we do not specify any value for this column, MySQL inserts the “A” as a default value The salary of the employee is saved in the employee_salary column. The data type of the column is INTEGERView the table definition using MySQL Workbench To view the table from MySQL workbench, Expand Employees database from Left pan expand tables.
