subquery

[whg001]

can not parse some sqls. would you like help me to solve this problem
example
"SELECT *, (SELECT group_concat(inner_url) inner_url FROM t_media_info b WHERE a.id = b.msg_id GROUP BY msg_id) inner_url WHERE f_step = 1 AND business_id IN (6, 3, 4, 8, 9, 12, 14, 15, 38, 39, 5) ORDER BY create_time DESC

To fix the issue we would have to make a breaking change, because the parser cannot handle "*" and columns/subselects in one query at the moment.

To workaround the problem you need to replace the "*" by single columns. Maybe a different parser (e.g. node-sql-parser) might handle your query.

Thank for your reply, I fixed this subquery。(I have taken over a project that involves this package. Recently, i need to add some feature to it)

/subquery_clause
  = '(' __ stmt:select_stmt __ ')' {
    stmt.parentheses = true
    return stmt
  }

// (SELECT * FROM `t_mi_partner_interface_privilege`) AS `total`
// t_aa.*
// (SELECT * FROM `t_mi_partner_interface_privilege`) `total`
// f_test aaa

  =
  (KW_ALL / (STAR !ident_start))?{
        return {
            expr: {
              type: 'column_ref',
              column: '*'
            },
            as: null
        }
    }
  / tbl:ident __ DOT __ STAR {
      return {
        expr: {
          type: 'column_ref',
          table: tbl,
          column: '*'
        },
        as: null
      };
    }
  / subquery:subquery_clause __ alias:alias_clause? {
      return { expr: subquery, as: alias || null, column:alias  };
    }
  / e:expr __ alias:alias_clause? {
      return { expr: e, as: alias };
    }
