controller：

    /**
     * 測試 inSql
     * @param tenantUser
     * @return List
     */
    @GetMapping(value = "/inSqlTest")
    public Result<?> inSqlTest(TenantUser tenantUser){
        LambdaQueryWrapper<TenantInfo> wrapper = new LambdaQueryWrapper<>();
        wrapper.inSql(TenantInfo::getId,
                "SELECT `tenant_id` FROM `tenant_user` WHERE `phone` = '"+tenantUser.getPhone()+"'");
        List<TenantInfo> list = tenantInfoService.list(wrapper);
        return Result.OK(list);
    }

控制臺打印sql：

SELECT
	*  
FROM
	tenant_info 
WHERE
	deleted = 0 
	AND (
	id IN ( SELECT `tenant_id` FROM `tenant_user` WHERE `phone` = '15013092652' ))

條件構造器的sql:

SELECT `tenant_id` FROM `tenant_user` WHERE `phone` = '15013092652'

(其中`tenant_user`.`tenant_id`對應`tenant_info`.`id`。)

測試結果如下：
