Fields

operation: SqlOperation

schema: String

table: String

select_columns: Option<String>

Columns to select (None = *)

filters: Vec<FilterCondition>

Filter conditions (WHERE)

orders: Vec<OrderClause>

ORDER BY clauses

limit: Option<i64>

LIMIT

offset: Option<i64>

OFFSET (from range)

single: bool

Whether to return a single row (enforced at execution)

maybe_single: bool

Whether to return zero or one row

count: CountOption

Count option

set_clauses: Vec<(String, usize)>

Insert/Update column-value pairs: Vec<(column, param_index)>

many_rows: Vec<Vec<(String, usize)>>

For insert_many/upsert_many: Vec of rows, each is Vec<(column, param_index)>

returning: Option<String>

RETURNING columns (None = don’t return, Some(“*”) = all)

conflict_columns: Vec<String>

ON CONFLICT columns (for upsert)

conflict_constraint: Option<String>

ON CONFLICT constraint name (alternative to columns)

ignore_duplicates: bool

When true, upsert generates ON CONFLICT DO NOTHING instead of DO UPDATE

schema_override: Option<String>

Schema override for per-query schema qualification

explain: Option<ExplainOptions>

EXPLAIN options (only for SELECT)

head: bool

Head mode: SELECT count(*) only, no rows
