SQL Code Generator Online

The SQL code generator reads a CREATE TABLE statement and writes the everyday queries you need for that table: select all rows, select one row by key, insert, update, and delete. Every statement uses bound parameters, so the output can go straight into a repository class, a DAO, or a stored query file without the SQL-injection risk of string concatenation.

What it generates

For a customers table with an auto-increment id, the output contains:

  • SELECT of all columns, plus a version filtered by the primary key.
  • INSERT INTO customers (email, full_name, …) VALUES (?, ?, …) — without the generated id.
  • UPDATE … SET for every non-key column, with the key in the WHERE clause.
  • DELETE … WHERE id = ?.

Use the Statements option to output only one of them.

Placeholder styles

Different drivers expect different parameter markers, so pick the one your stack uses: positional ?, PostgreSQL-style numbered $1, $2, or named :email and @email. Numbered placeholders restart at $1 in every statement, matching how you pass parameter arrays to each query.

Dialect-aware quoting

Table and column names are quoted for the chosen database — backticks for MySQL, double quotes for PostgreSQL, SQLite, and Oracle, and square brackets for SQL Server — so reserved words like order or user are safe to use as identifiers.

Input tips

The parser accepts CREATE TABLE from any of the supported databases, including IF NOT EXISTS, schema-qualified names, inline and table-level primary keys, and trailing table options such as ENGINE=InnoDB. If no CREATE TABLE is found, you get a clear error message.

Don't have a table definition yet? Design one in the SQL Table Generator. Format and review scripts in the SQL Viewer, and generate INSERT statements from spreadsheet data with CSV to SQL.

Frequently Asked Questions

Use ? for MySQL drivers, JDBC, SQLite, and PDO positional parameters; $1, $2 for PostgreSQL drivers such as node-postgres; :name for PDO named parameters, Oracle, and SQLAlchemy text(); and @name for SQL Server and ADO.NET/Dapper.

It uses the table's primary key — either marked inline (id INT PRIMARY KEY) or with a PRIMARY KEY (…) constraint, including composite keys. If the table has no primary key, the first column is used.

Columns declared as AUTO_INCREMENT, SERIAL, or IDENTITY are generated by the database, so they are left out of the INSERT column list and the UPDATE SET list.

The generator works on one table at a time and uses the first CREATE TABLE statement it finds. Paste each table separately to get its statements.
