import (
	_ "github.com/aacfactory/fns-contrib/databases/mysql"
)
Define struct

See DAC.

Switch package

Use github.com/aacfactory/fns-contrib/databases/mysql insteadof github.com/aacfactory/fns-contrib/databases/sql/dac.

entry, err = mysql.Insert[Table](ctx, entry) // insteadof dac
Code generator in fn

Add annotation code writer

generates.New(generates.WithAnnotations(mysql.FAG()...))

Use @mysql:transaction annotation. params are readonly and isolation.

  • readonly: set the transaction to be readonly.
  • isolation: use spec isolation. default is use isolation of config.
    • ReadCommitted
    • ReadUncommitted
    • WriteCommitted
    • RepeatableRead
    • Snapshot
    • Serializable
    • Linearizable
// @fn some
// ... some func use transaction
// @mysql:transaction
func some(ctx context.Context, param Param) (result Result, err error) {
	// ...
	return
}

Use @mysql:use annotation to switch datasource service. param is service name and mark it before @mysql:transaction.

// @fn some
// ... some func use transaction
// @mysql:use mysql1
func some(ctx context.Context, param Param) (result Result, err error) {
	// ...
	return
}
