SQL Code Generator for CRUD and UPSERT SQL Statements
Enter a table name and columns, mark the primary key, and generate CRUD statements for MySQL, PostgreSQL, SQLite, SQL Server, or Oracle. The SQL Code Generator also creates UPSERT syntax suited to the selected dialect, including ON CONFLICT, ON DUPLICATE KEY, or MERGE, and parameterized INSERT snippets in JavaScript, Python, PHP, and Java.
The SQL Code Generator helps developers create SQL statements from a table name, column names, and a marked primary key. It generates common CRUD statements—SELECT, INSERT, UPDATE, and DELETE—along with UPSERT, CREATE INDEX, and ALTER statements. You can use it to prepare SQL for MySQL, PostgreSQL, SQLite, SQL Server, or Oracle.
Choose the database dialect you are working with and provide the table details. UPSERT syntax is adapted to the selected dialect: the generated form may use ON CONFLICT, ON DUPLICATE KEY, or MERGE. The tool also creates parameterized INSERT snippets in JavaScript, Python, PHP, and Java, giving you a starting point for adding inserts to application code.
SQL dialects share many concepts, but their syntax can differ. Generating statements for a specific dialect is useful when you want a starting point that better matches your database rather than drafting every statement manually. SQL describes database operations, while JavaScript, Python, PHP, and Java are programming languages; the parameterized INSERT snippets connect those two parts of a development workflow.
The SQL Code Generator runs entirely in your browser. Your input is processed on your device and is not uploaded, stored, or sent to a server. After the page has loaded, it continues to work without an internet connection.
This tool is useful for developers and DevOps engineers preparing database statements, building application code, or working with more than one SQL dialect. Generate the output you need, then review it for your table and project before using it.
Step 1: Enter the table name and its columns. These details are used to build statements for your table.
Step 2: Mark the primary key. This helps define the key used in the generated SQL.
Step 3: Choose a SQL dialect from MySQL, PostgreSQL, SQLite, SQL Server, or Oracle, and set the available options.
Step 4: Generate the SQL, then copy the statements or parameterized INSERT snippet you need.
Use case: Prepare SQL statements for test, fixture, or seed-data workflows without writing each CRUD statement from scratch.
Use case: Generate SELECT, INSERT, UPDATE, and DELETE statements for a table using its name, columns, and primary key.
Use case: Produce UPSERT syntax for a supported database dialect, such as ON CONFLICT, ON DUPLICATE KEY, or MERGE.
Use case: Create SQL for MySQL, PostgreSQL, SQLite, SQL Server, or Oracle when working across different database projects.
Use case: Get a parameterized INSERT snippet in JavaScript, Python, PHP, or Java to use as a starting point in application code.
Use case: Generate CREATE INDEX or ALTER statements as part of a database development workflow.
