![]() The backtick character is shown on a US keyboard layout. Figure 1 shows where you find it on a US keyboard layout: Figure 1. You should use a pair of backticks to enclose identifiers instead. Using square brackets in table and column names will trigger an error in MySQL. However, if you need to create a table in another database in the same script, this is a must. The database and schema names are optional. Why? Because in MySQL, a schema is synonymous with a database. Here’s how it goes: CREATE TABLE database_name.table_nameĭid you notice the table name preceded by the database name? Now, here’s a T-SQL equivalent format you are familiar with:ĬREATE TABLE database_name.schema_name.table_name One of the noticeable syntax differences in MySQL CREATE TABLE is the absence of a schema name. Let’s start the comparison by defining the table name. Create Table Statement in MySQL and T-SQL The SQL Server version used here is SQL Server 2019.The MySQL version used here is MySQL 8 using the InnoDB storage engine.However, before we proceed, let’s clarify a few points: So, we will only cover 5 basic points to get you up and running with MySQL CREATE TABLE command. Besides, the fastest way to learn a new SQL database platform is by comparing its common functionality and syntax. In addition, its default value is the current timestamp of the operating system on which the MariaDB server runs.īecause we don’t explicitly specify the storage engine for the projects table, it takes InnoDB as the storage engine.Are you a T-SQL developer learning the basics of MySQL? Then, one of the things you might want to learn is MySQL CREATE TABLE statement. The created_at column is a timestamp column that accepts date and time values.The cost is a decimal column that also does not accept null values.The begin_date and end_date are the date columns.Because it has a not null constraint, you cannot insert null values into this column. The project_name is a variable-length character with a maximum size of 255 characters.It means that a value in the project_id column will uniquely identify a row in the table. In addition, the project_id column is the primary key specified by the primary key constraint at the end of the table. It has the auto_increment property, therefore, MariaDB will automatically generate a sequential number when you insert a row into the table. ![]() To define a column for a table, you use the following syntax:Ĭreated_at timestamp default current_timestamp, The InnoDB is a good transaction storage engine that supports ACID, referential integrity, and crash recovery. MariaDB has made InnoDB as the default storage engine since version 10.2. ![]() If you skip the storage engine, MariaDB will use the InnoDB by default. Finally, optionally specify a storage engine for the table in the engine clause.Fourth, specify table constraints like primary key, foreign key, check, and unique after the column list.Third, specify a list of columns for the table within the parentheses, the columns are separated by commas (,).Second, use the if not exists option to conditionally create the new table only if it does not exist.The table name must be unique within a database. First, specify the name of the table that you want to create after the create table keywords.Create table table_name(Ĭode language: SQL (Structured Query Language) ( sql ) ![]()
