var ErrNoSQLExecutor = errors.New("sqlbind: no SQL executor in context")

ErrNoSQLExecutor reports that a Context does not contain a database executor. It is returned instead of panicking so generated Context wrappers remain ordinary error-returning APIs.

Functions ¶

func Bool ¶

func Bool(row Row, column string) (bool, error)

func Float64 ¶

func Float64(row Row, column string) (float64, error)

func ForEach ¶

func ForEach(rows *sql.Rows, fn func(Row) error) error

ForEach scans rows without retaining the full result.

func Int ¶

func Int(row Row, column string) (int, error)

func Int64 ¶

func Int64(row Row, column string) (int64, error)

func Key ¶

func Key(row Row, column string) (key string, present bool, err error)

Key returns a stable grouping key. present is false for SQL NULL.

func RegisterScanRows ¶

func RegisterScanRows[T any](fn func(*sql.Rows) ([]T, error))

RegisterScanRows registers a generated SQL tree scanner for T.

func RequiredKey ¶

func RequiredKey(row Row, column string) (string, error)

RequiredKey is Key with NULL rejected for a root object.

func ScanRows ¶

func ScanRows[T any](rows *sql.Rows) ([]T, error)

ScanRows maps joined SQL rows into a grouped object tree using generated code.

func String ¶

func String(row Row, column string) (string, error)

func WithSQLExecutor ¶ added in v0.1.6

func WithSQLExecutor(ctx context.Context, executor SQLExecutor) context.Context

WithSQLExecutor returns a child Context containing a database executor. Framework transaction middleware can store a *sql.Tx for generated <Component>Context wrappers to resolve.

Types ¶

type Row ¶

type Row map[string]any

Row is a SQL row indexed by result column name.

type SQLExecutor ¶ added in v0.1.6

type SQLExecutor interface {
	ExecContext(context.Context, string, ...any) (sql.Result, error)
	QueryContext(context.Context, string, ...any) (*sql.Rows, error)
}

SQLExecutor is implemented by *sql.DB, *sql.Conn, and *sql.Tx.

func SQLExecutorFromContext ¶ added in v0.1.6

func SQLExecutorFromContext(ctx context.Context) (SQLExecutor, error)

SQLExecutorFromContext returns the executor installed by WithSQLExecutor.
