## Overview

The Table Schema Generator is a streamlined utility designed to help developers quickly create SQL table definitions by converting structured column data into ready-to-use CREATE TABLE statements.

## Inputs

- **Table Name** (text): Enter table name...
- **Database Type** (select)
- **Columns (JSON or name:type:nullable:pk:auto:default)** (textarea): \[{"name":"id","type":"INT","nullable":false,"primaryKey":true,"autoIncrement":true,"defaultValue":""},{"name":"username","type":"VARCHAR(255)","nullable":false,"primaryKey":false,"autoIncrement":false,"defaultValue":""}\]

## When to use

- When you need to rapidly prototype database structures for new applications.
- When migrating data models between different SQL database engines.
- When you want to ensure consistent column definitions across multiple development environments.

## How it works

- Enter your desired table name to define the target entity.
- Select your preferred database engine, such as MySQL, PostgreSQL, SQLite, or SQL Server.
- Input your column specifications using the JSON format to define names, types, constraints, and primary keys.
- Generate the SQL script instantly to copy and execute in your database management tool.

## Use cases

- Standardizing database schema documentation for team projects.
- Quickly generating boilerplate code for database migration scripts.
- Testing different data types and constraints during the initial design phase of a database.

## Frequently asked questions

### Which SQL dialects are supported?

The tool currently supports MySQL, PostgreSQL, SQLite, and SQL Server.

### Can I define primary keys and auto-increment fields?

Yes, you can specify primary keys and auto-increment properties directly within the column configuration JSON.

### Is the output compatible with all SQL clients?

Yes, the generated output provides standard SQL syntax compatible with most major database management systems and command-line interfaces.

### Do I need to manually write the SQL syntax?

No, the tool automatically handles the syntax generation based on the parameters and column definitions you provide.

### Can I save my schema configurations?

The tool generates the SQL code for immediate use; you can copy the output to a text file to save your schema definitions locally.
