Overview

UpdateBuilder builds parameterized UPDATE … SET … WHERE statements:

import com.github.ezframework.javaquerybuilder.query.builder.QueryBuilder;
import com.github.ezframework.javaquerybuilder.query.sql.SqlResult;

SqlResult result = QueryBuilder.update("users")
    .set("status", "inactive")
    .set("updated_at", "2026-01-01")
    .whereEquals("id", 42)
    .build();

// → UPDATE users SET status = ?, updated_at = ? WHERE id = ?
// Parameters: ["inactive", "2026-01-01", 42]

---

Multiple conditions

SqlResult result = QueryBuilder.update("products")
    .set("price", 9.99)
    .whereEquals("category", "sale")
    .whereGreaterThanOrEquals("stock", 1)
    .build();
// → UPDATE products SET price = ? WHERE category = ? AND stock >= ?

---

OR condition

SqlResult result = QueryBuilder.update("users")
    .set("role", "user")
    .whereEquals("role", "guest")
    .orWhereEquals("role", "temp")
    .build();
// → UPDATE users SET role = ? WHERE role = ? OR role = ?

---

RETURNING (PostgreSQL)

RETURNING is appended inline after the WHERE clause. The caller is responsible for using a PostgreSQL connection; the clause is emitted regardless of which dialect is passed to build().

SqlResult result = QueryBuilder.update("users")
    .set("status", "active")
    .whereEquals("id", 7)
    .returning("id", "updated_at")
    .build();

// → UPDATE users SET status = ? WHERE id = ? RETURNING id, updated_at
// Parameters: ["active", 7]
