What is GoSQLX?

GoSQLX is a production-ready SQL parsing SDK for Go. It tokenizes, parses, and generates ASTs from SQL with zero-copy optimizations and intelligent object pooling - handling 1.25M+ operations per second with sub-microsecond latency.

ast, _ := gosqlx.Parse("SELECT u.name, COUNT(*) FROM users u JOIN orders o ON u.id = o.user_id GROUP BY u.name")
// → Full AST with statements, columns, joins, grouping - ready for analysis, transformation, or formatting

Why GoSQLX?

• Not an ORM - a parser. You get the AST, you decide what to do with it.
• Not slow - zero-copy tokenization, sync.Pool recycling, no allocations on hot paths.
• Not limited - PostgreSQL, MySQL, SQL Server, Oracle, SQLite, Snowflake. CTEs, window functions, MERGE, set operations.
• Not just a library - CLI, VS Code extension, GitHub Action, MCP server, WASM playground, Python bindings.

Get Started in 60 Seconds

go get github.com/ajitpratap0/GoSQLX

package main

import (
    "fmt"
    "github.com/ajitpratap0/GoSQLX/pkg/gosqlx"
)

func main() {
    // Parse any SQL dialect
    ast, _ := gosqlx.Parse("SELECT * FROM users WHERE active = true")
    fmt.Printf("%d statement(s)\n", len(ast.Statements))

    // Format messy SQL
    clean, _ := gosqlx.Format("select id,name from users where id=1", gosqlx.DefaultFormatOptions())
    fmt.Println(clean)
    // SELECT
    //   id,
    //   name
    // FROM users
    // WHERE id = 1

    // Catch errors before production
    if err := gosqlx.Validate("SELECT * FROM"); err != nil {
        fmt.Println(err) // → expected table name
    }
}
