SQL Table Generator

Q: What does CREATE TABLE do?

The CREATE TABLE statement is a fundamental SQL command used to create a new table in a database. It defines the table's name and the properties of each column, including data types and constraints.

Q: Why are there different SQL Dialects?

Different database systems like MySQL, PostgreSQL, and SQL Server have their own variations or 'dialects' of SQL. They might use different data type names or syntax for features like auto-incrementing keys. Our tool handles these differences for you.

Q: What do the column options mean?

PK stands for Primary Key, a unique identifier for each record. AI stands for Auto Increment, which automatically generates a unique number for new records. Not Null (NN) ensures a column must have a value.

Q: Is the data I enter kept private?

Yes, your data is private. The tool runs entirely in your browser. Your table schema and generated SQL are never sent to our servers.

About the SQL Table Generator

We built this tool to speed up the process of creating database schemas. Writing `CREATE TABLE` statements by hand can be tedious and prone to syntax errors. Our visual generator provides an interactive interface to define your table's structure, including column names, data types, and constraints like Primary Keys and Auto-Increment. It's perfect for developers, database administrators, and students who need to create SQL schemas quickly and accurately.

How to Use the Tool

Start by setting your "Table Name" and choosing the correct "SQL Dialect" for your database.
In the "Columns" section, you can edit the pre-filled example rows. Click "Add Column" to add more fields.
For each column, enter a name, select a data type from the dropdown, and optionally specify a length (e.g., for `VARCHAR`) and a default value.
Use the checkboxes to set a column as a Primary Key, Auto Incrementing, or Not Null.
Use the arrow and 'x' buttons to reorder or remove columns.
The `CREATE TABLE` statement in the output panel will update in real-time. Copy or download the code when you are ready.

Frequently Asked Questions

What does `CREATE TABLE` do?

The `CREATE TABLE` statement is a fundamental SQL command used to create a new table in a database. The statement defines the name of the table and the names and properties of each column, including their data types (like `INT` or `VARCHAR`) and any constraints.

Why are there different SQL Dialects?

While SQL is a standard, different database systems like MySQL, PostgreSQL, and SQL Server have their own variations or "dialects." They often have different names for data types or use slightly different syntax for things like auto-incrementing keys. Our tool automatically adjusts the generated code to match the syntax of your chosen dialect.

What do the column options mean?

Primary Key (PK): This constraint uniquely identifies each record in a table. A primary key must contain unique values and cannot contain NULL values.
Auto Increment (AI): This allows a unique number to be generated automatically when a new record is inserted into a table. It's commonly used for primary key columns.
Not Null (NN): This constraint ensures that a column cannot have a NULL value. It forces a field to always contain a value. You can uncheck this to allow `NULL` values.

Is the data I enter kept private?

Yes, your data is completely private. This tool is built with JavaScript and runs entirely in your web browser. Your table schema and generated code are never sent to our servers. Your work remains secure on your own computer.
