feat: implement Returning method for UpdateBuilder and DeleteBuilder
 2025-07-25 11:07:39 +08:00
Huan Du 8e5ccbbee2 feat: implement Returning method for UpdateBuilder and DeleteBuilder 
Fixes #210

This commit adds the Returning method to both UpdateBuilder and DeleteBuilder,
following the same implementation pattern as InsertBuilder.

Changes:
- Add returning field to UpdateBuilder and DeleteBuilder structs
- Add updateMarkerAfterReturning and deleteMarkerAfterReturning markers
- Implement Returning methods for both builders
- Add RETURNING clause support for PostgreSQL and SQLite flavors
- Add comprehensive test coverage including:
  - Basic functionality tests
  - Flavor-specific behavior tests
  - Edge cases (empty, single, multiple columns)
  - Complex scenarios (ORDER BY, LIMIT, CTE)
  - SQL injection compatibility
  - Method chaining validation

The RETURNING clause is properly positioned after LIMIT and is ignored
for database flavors that don't support it (MySQL, SQL Server, CQL,
ClickHouse, Presto).

Example usage:
  ub := Update("users").Set("name = ?", "John").Where("id = ?", 1).Returning("id", "updated_at")
  db := DeleteFrom("users").Where("status = ?", "inactive").Returning("id", "deleted_at")

Fix #195 the order of LIMIT and OFFSET clauses when using the Presto flavor

Bar Weiss feef77c099 Fix the order of LIMIT and OFFSET clauses when using the Presto flavor (issue #195) 
Queries that have both a limit and an offset build a query with a limit clause *before* the offset clause.

```go
fmt.Println(Select("*").From("table").Offset(5).Limit(10))
// SELECT * FROM table LIMIT 10 OFFSET 5
```

This seems to generate syntax errors in Trino. [Presto documentation specifies OFFSET before LIMIT](https://prestodb.io/docs/current/sql/select.html#limit-clause) in the SELECT statement documentation too, but is not very explicit about the reverse not being supported.

If the OFFSET and LIMIT clauses are swapped, the query succeeds.

Expected:

```go
fmt.Println(Select("*").From("table").Offset(5).Limit(10))
// SELECT * FROM table OFFSET 5 LIMIT 10
```
