add result type: gorm.DB, *gorm.DB

User Case Description

type Querier interface {
	// FindByCondition
	//
	// where("
	// {{if role != nil}}
	//   	{{if role.Name !=""}}
	//			 name LIKE concat("%",@role.Name,"%")
	//       {{end}}
	// {{end}}
	// ")
	FindByCondition(role *gen.T) (*gorm.DB, error)
}

execute generate.go, and then get role.gen.go

func (s systemRoleDo) FindByCondition(role *model.SystemRole) (executeSQL *gorm.DB, err error) {
	var params []interface{}

	var generateSQL strings.Builder
	if role != nil {
		if role.Name != "" {
			params = append(params, role.Name)
			generateSQL.WriteString("name LIKE concat(\"%\",?,\"%\") ")
		}
	}

	executeSQL = s.UnderlyingDB().Where(generateSQL.String(), params...) // ignore_security_alert
	err = executeSQL.Error

	return
}
