SQL Where like filter expression for entql and gorm

go-miniquery

SQL Where like safe filter expression for entql and gorm

gorm

• use reflect to get model graph
• support join relation

package main

import "gorm.io/gorm"

func TestMiniQuery() {
	var db *gorm.DB
	// build to username = ? and Profile__age > ?
	db.Model(User{}).Scopes(ApplyMiniQuery(`username="wener" && Profile.age > 18`)).Rows()
}

entql

• generate entsql - recommend
  • depends on generated graph - will validate when build
  • support edge filter
• generate entql
  • function is not as complete as entsql
  • do not depends on generated graph - validate when entql to sql

package main

import "entgo.io/ent/dialect/sql"

func TestEntSQL() {
	var s *sql.Selector
	s.Where(sql.P(func(builder *sql.Builder) {
		b := &entmq.MiniQLToEntSQLBuilder{
			Node:        node,          // *sqlgraph.Node
			Graph:       schemaGraph,   // *sqlgraph.Schema
			QueryString: query,
		}
		builder.Join(b)
		err := b.Err()
		if err != nil {
			panic(errors.Wrap(err, "invalid query"))
		}
	}))
}
