Overview

Package types provides common SQL column types and model field embeds.

Basic time types (package sqltime)

  • sqltime.Datetime: calendar date-time stored as a SQL datetime type (MySQL DATETIME, PostgreSQL TIMESTAMP).
  • sqltime.Timestamp: integer unix timestamp at second precision.
  • sqltime.TimestampMilli: integer unix timestamp at millisecond precision.

Operation-time embeds over sqltime.Datetime

Combinations of CreatedAt / UpdatedAt / DeletedAt for record lifecycle. Soft-deletion variants (CreationModificationDeletion*) implement SoftDeletion. Aliases: OperationDatetime, OperationDatetimePrecise.

Second precision:

  • CreationDatetime
  • CreationModificationDatetime
  • CreationModificationDeletionDatetime
  • sqlops.CreationDatetime
  • sqlops.CreationModificationDatetime
  • sqlops.CreationModificationDeletionDatetime

Millisecond precision (Datetime with precision=3):

  • CreationDatetimeMilli
  • CreationModificationDatetimePrecise
  • CreationModificationDeletionDatetimePrecise
  • sqlops.CreationDatetimeMilli
  • sqlops.CreationModificationDatetimePrecise
  • sqlops.CreationModificationDeletionDatetimePrecise

Column names differ: types uses an `f_` prefix (e.g. f_created_at); sqlops uses unprefixed names (e.g. created_at).

Operation-time embeds over sqltime.Timestamp / TimestampMilli

Second precision (sqltime.Timestamp):

  • CreationTime
  • CreationModificationTime
  • CreationModificationDeletionTime
  • sqlops.CreationTime
  • sqlops.CreationModificationTime
  • sqlops.CreationModificationDeletionTime

Millisecond precision (sqltime.TimestampMilli):

  • CreationTimePrecise
  • CreationModificationTimePrecise
  • CreationModificationDeletionTimePrecise
  • sqlops.CreationTimePrecise
  • sqlops.CreationModificationTimePrecise
  • sqlops.CreationModificationDeletionTimePrecise

Soft-deletion variants implement SoftDeletion. Aliases: OperationTime, OperationTimePrecise. Same f_ vs unprefixed column naming as the Datetime embeds above.

Bool

types.Bool is a three-state boolean (TRUE / FALSE / UNKNOWN ) for avoiding ambiguity with Go's two-state bool. Use Boolean(b) to convert from bool.

Text

types.Text wraps SQL TEXT. An empty string is stored as NULL.

Blob

types.Blob wraps SQL BLOB (BYTEA on PostgreSQL). An empty slice is stored as NULL.

Decimal

types.Decimal is a high-precision decimal for monetary and exact numeric columns.

JSON

types.JSONArray and types.JSONObject marshal Go values to/from JSON columns.

Other

AutoIncID is an embed for an auto-increment primary key (f_id). ID is a generic unsigned identifier type.

Marker interfaces CreationMarker, ModificationMarker, DeletionMarker, and SoftDeletion describe create / update / soft-delete behavior used by model code generation. +genx:doc

type Serial added in v0.3.7 

type Serial struct {
	// ID 自增主键
	ID int64 `db:"f_id,autoinc" json:"-"`
}

Serial is an auto-increment primary key embed (column f_id).

ID is int64 rather than uint64 for two reasons:

  1. SQL integer types used for identity columns are signed in the SQL standard and in common dialects (INTEGER / BIGINT; PostgreSQL SERIAL / BIGSERIAL map to signed integers). Unsigned 64-bit integers are not a portable auto-increment type across databases.

  2. database/sql treats integer driver.Value as int64. Passing a uint64 with the high bit set (value >= 1<<63) fails with "uint64 values with high bit set are not supported". Result.LastInsertId also returns int64. Using int64 keeps insert args, scan targets, and last-insert-id in one representation without conversion edge cases.

	// SoftDeletion returns soft deletion field name, modification fields if any,
