【go】xorm分类统计及多表联查

1 分类统计

• 1 sql

SELECT grade_protection_level AS type, count(grade_protection_level) AS count
FROM `vital_7jvebmrryff3_asset`
WHERE (field_group = '应用信息')
        AND (asset_life_cycle = '正式')
        AND (status = 1)
GROUP BY  grade_protection_level
ORDER BY  count(grade_protection_level) DESC

• 2 xorm

func (*dAnalyse) FindCount(orgIds []any) ([]model.Analyse[int], error) {
	res := []model.Analyse[int]{}     // 映射结构为切片
	err := AppsWhere().Select("grade_protection_level as type, count(grade_protection_level) as count").
		In("organization_id", orgIds).   // sql中删去了此条件
		GroupBy("grade_protection_level").
		OrderBy("count(grade_protection_level) desc").
		Find(&res)
	return res, err
}

2 多表联查

• xorm

func (*dAnalyse) FindTotalOrderDesc(orgNames []string) ([]model.Analyse[int], error) {
	res := []model.Analyse[int]{}
	err := AppsWhere().Select("name as org, count(grade_protection_status) as count").
		Join("INNER", "vital_7jvebmrryff3_organization", "vital_7jvebmrryff3_asset.organization_id = vital_7jvebmrryff3_organization.id").   // 内联INNER,外联LEFT
		In("name", orgNames).
		Where("grade_protection_status = '未定级'").
		GroupBy("name").
		OrderBy("count(grade_protection_status) desc").Find(&res)
	return res, err
