resource_path = gui.Application.instance.resource_path

这是一个赋值语句，它的作用是将gui.Application.instance.resource_path的值赋给变量resource_path。具体来说，gui.Application.instance是一个单例对象，表示当前应用程序的实例，resource_path是它的一个属性，表示应用程序所使用的资源文件的路径。这条语句的目的是获取应用程序的资源文件路径并将其存储在变量resource_path中，以便在后续的代码中使用。

select a.*,count(distinct b.id) as 'topicNum',count(distinct c.id) as 'groupNum' from resource_instance_rocketmq a left join resource_rocketmq_topic b on a.instance_id = b.instance_id left join resource_rocketmq_group c on a.instance_id = c.instance_id where a.instance_name like '%gaotu%' group by a.instance_id order by topicNum asc limit 3 offset 2

以下是将该 SQL 查询语句转换为 Golang 代码的示例：

package main

import (
	"context"
	"database/sql"
	"fmt"

	_ "github.com/go-sql-driver/mysql"
)

func main() {
	db, err := sql.Open("mysql", "user:password@tcp(host:port)/database")
	if err != nil {
		panic(err.Error())
	}
	defer db.Close()

	query := `
		SELECT a.*, COUNT(DISTINCT b.id) AS topicNum, COUNT(DISTINCT c.id) AS groupNum
		FROM resource_instance_rocketmq a
		LEFT JOIN resource_rocketmq_topic b ON a.instance_id = b.instance_id
		LEFT JOIN resource_rocketmq_group c ON a.instance_id = c.instance_id
		WHERE a.instance_name LIKE ?
		GROUP BY a.instance_id
		ORDER BY topicNum ASC
		LIMIT 3 OFFSET 2
	`
	rows, err := db.QueryContext(context.Background(), query, "%gaotu%")
	if err != nil {
		panic(err.Error())
	}
	defer rows.Close()

	for rows.Next() {
		// 读取查询结果，并进行处理
	}
}

请将代码中的 `user`、`password`、`host`、`port`、`database` 分别替换为您的 MySQL 数据库的实际连接信息。同时，您需要安装 `go-sql-driver/mysql` 包以便 Golang 代码连接 MySQL 数据库。请注意，为了防止 SQL 注入攻击，我们使用了 `?` 占位符，并将查询条件 `"gaotu"` 作为参数传入 `QueryContext` 方法中。

SELECT a.comm_id, c.Title AS house_keeper_name, ( SELECT build.id FROM erp_base.tb_base_masterdata_resource AS resource INNER JOIN erp_base.tb_base_masterdata_resource AS unit ON unit.id = resource.parent_id INNER JOIN erp_base.tb_base_masterdata_resource AS build ON build.id = unit.parent_id WHERE resource.id = a.resource_id ) AS resource_group, b.resource_type FROM tb_charge_receipts_detail a LEFT JOIN erp_base.tb_base_masterdata_resource b ON a.resource_id = b.id LEFT JOIN erp_base.rf_dictionary c ON b.house_keeper = c.id GROUP BY a.comm_id, c.Title, resource_group, b.resource_type 在mysql中报SELECT list is not in GROUP BY clause and contains nonaggregated column 'erp_charge.a.resource_id' which is not functionally dependent on columns in GROUP BY clause; this is incompatible with sql_mode=only_full_group_by 如何做sql的修改

根据错误提示，可以尝试修改sql_mode，去掉only_full_group_by，或者添加a.resource_id到GROUP BY子句中，但是这样可能会导致查询结果不准确。为了避免这种情况，可以使用聚合函数来替代a.resource_id，比如使用MAX(a.resource_id)。

修改后的SQL语句如下：

SELECT a.comm_id, c.Title AS house_keeper_name,
(SELECT build.id FROM erp_base.tb_base_masterdata_resource AS resource
INNER JOIN erp_base.tb_base_masterdata_resource AS unit ON unit.id = resource.parent_id
INNER JOIN erp_base.tb_base_masterdata_resource AS build ON build.id = unit.parent_id
WHERE resource.id = a.resource_id) AS resource_group,
b.resource_type
FROM tb_charge_receipts_detail a
LEFT JOIN erp_base.tb_base_masterdata_resource b ON a.resource_id = b.id
LEFT JOIN erp_base.rf_dictionary c ON b.house_keeper = c.id
GROUP BY a.comm_id, c.Title, resource_group, b.resource_type
