Example Usage

use prax_query::sequence::{Sequence, SequenceBuilder};

// Define a sequence
let seq = Sequence::builder("order_number")
    .start(1000)
    .increment(1)
    .min_value(1)
    .max_value(i64::MAX)
    .cycle(false)
    .cache(20)
    .build();

// Generate SQL
let create_sql = seq.to_postgres_create_sql();

// Get next value
let next_val_sql = seq.nextval_sql(DatabaseType::PostgreSQL);
