// Package dbx provides database utilities built on go-jet/jet and go-toolkit/app.
|
|
//
|
|
// # Module lifecycle
|
|
//
|
|
// Call [ModuleDB] once to register the database [app.Module], then use [SQLO]
|
|
// to access the connection pool. [CurrentDialect] reports the configured dialect.
|
|
// Only one database per process is supported.
|
|
//
|
|
// # Query and mutation helpers
|
|
//
|
|
// [Fetch], [FetchOne], [Query], [Insert], [Update], [Delete], and their Must*
|
|
// and Context variants wrap Jet [Statement] execution with consistent error
|
|
// semantics. [UpdateOne] requires at least one row affected.
|
|
// [WithTx] and [WithTxValue] run functions inside SQL transactions.
|
|
//
|
|
// # Jet column utilities
|
|
//
|
|
// Dialect-neutral type aliases ([Column], [ColumnList]) and helpers for column
|
|
// lists ([NormalCols], [ContainsCol]) and expression building ([ExprValues]).
|
|
// [QueryCount] and [BuildQueryCountFn] support pagination total counts.
|
|
//
|
|
// Partial-update helpers ([ApplyPtr], [ApplyVal]) track changed fields for
|
|
// repository patch logic.
|
|
//
|
|
// # Identifier types
|
|
//
|
|
// [StringKSUID] and [BinaryKSUID] wrap segmentio/ksuid with storage-specific
|
|
// SQL encoding. Both implement [ApplyInterface] via Equal and IsZero for use
|
|
// with [ApplyInterfacePtr]. Both share identical GraphQL string scalar transit.
|
|
// Choose StringKSUID for text columns (VARCHAR, TEXT); choose BinaryKSUID for
|
|
// binary columns (BINARY(20), BYTEA). [ParseStringKSUIDAny] and
|
|
// [ParseBinaryKSUIDAny] accept flexible input for API boundaries.
|
|
//
|
|
// [JSONB] provides map-based JSON column scanning for Postgres JSONB and MySQL JSON.
|
|
//
|
|
// # GraphQL scalars
|
|
//
|
|
// [MarshalUint64] and [UnmarshalUint64] provide JS-safe uint64 serialization for
|
|
// gqlgen without importing gqlgen directly.
|
|
//
|
|
// # Pointer and string utilities
|
|
//
|
|
// [Ptr], [Val], [TrimPtr], [StringToFilter], and related helpers for nullable
|
|
// field handling in repository code.
|
|
//
|
|
// # Debug logging
|
|
//
|
|
// Enable [DBConfig.DebugLog] and blank-import dbxm (MySQL) or dbxp (Postgres)
|
|
// to register Jet query debug output. Setup returns an error if DebugLog is
|
|
// enabled without the matching blank import.
|
|
//
|
|
// # Dialect notes
|
|
//
|
|
// Use [Insert] with LastInsertId on MySQL; Postgres callers should use
|
|
// [InsertReturning]. [InsertReturning] and [UpdateReturning] require Jet
|
|
// RETURNING clauses.
