What is SQL Code Generator?

A SQL code generator turns table details into practical statement templates. Instead of repeatedly writing column lists for INSERT statements, SELECT projections, UPDATE assignments, and DELETE conditions, you define the table once and let the tool assemble clean SQL for your target database.

This generator focuses on starter code for application queries and migrations. It can output a complete CRUD set or one statement at a time, quote identifiers for the selected dialect, and switch between prepared placeholders and literal sample values. Primary-key columns are used in WHERE clauses so generated SELECT, UPDATE, and DELETE statements are immediately useful.

How to Use SQL Code Generator

1

Enter the table name and choose a SQL dialect.

2

Pick one SQL statement or the full CRUD set.

3

Add columns with SQL types, sample values, nullability, and primary-key flags.

4

Choose prepared placeholders or literal sample values.

5

Copy the generated SQL code.

Common Use Cases

  • Scaffolding CRUD queries for a new table.
  • Creating prepared SQL templates for application code.
  • Producing migration examples during schema design.
  • Comparing placeholder styles across SQL dialects.
  • Building quick examples for documentation or tutorials.

Example Input and Output

A users table with a primary key generates a prepared UPDATE statement with a WHERE clause.

Configuration
Dialect: PostgreSQL, table: users, columns: id PK, name, email, prepared placeholders enabled.
Generated SQL
UPDATE "users"
SET "name" = $1, "email" = $2
WHERE "id" = $3;

Privacy

All SQL generation happens locally in your browser. Table and column details are not sent to a server.

Prepared statements

Prepared placeholders are the safer default for application code. Bind values through your database driver rather than interpolating user input into SQL strings.

Frequently Asked Questions

Does this execute SQL against a database?
No. It only generates SQL text in your browser. Review the statement and run it in your own database client or migration tool.
What placeholder style is used?
PostgreSQL uses $1, $2, and so on. SQL Server uses named @column placeholders. MySQL, SQLite, and Standard SQL use question-mark placeholders.
How are WHERE clauses generated?
Columns marked as primary keys are used in WHERE clauses. If no primary key is selected, the first column is used as a fallback so the statement remains complete.
Can I generate only INSERT or only SELECT?
Yes. Use the Output dropdown to switch between a full CRUD set and individual CREATE, INSERT, SELECT, UPDATE, or DELETE statements.
Does this support joins or foreign keys?
No. This tool generates single-table starter statements. Add joins, constraints, and indexes manually as your schema requires.
