在postgresql中，内部联接在单行中给出id的结果

这是我的疑问：

  SELECT    (sc.contract_number) AS id,
            to_char(sc.contract_date, 'DD/MM/YYYY') AS "Contract Date",
            (sc.cust_name) AS "Customer Name",
            (
             SELECT pt.product_desc
             FROM   product_product pp,
                    product_template pt
             WHERE  pt.id = pp.product_tmpl_id AND
                    type = 'service' AND
                    pt.name LIKE sc.pms_lines
            ) AS "PMS",
            CASE WHEN sc.parent_ref IS NULL THEN ROUND(sc.basic_amount)
                 ELSE 0
            END AS "New Amount",
            CASE WHEN sc.parent_ref IS NULL THEN 0
                 ELSE ROUND(sc.basic_amount)
            END AS "Renew Amount",
            ROUND(sc.service_tax_amount + sc.edu_tax_amount +
                  sc.hs_edu_tax_amount) AS "Service Tax",
            ROUND(sc.grand_total_amount) AS "Total"
  FROM      sale_contract sc
  INNER JOIN inspection_costing_line icl ON (sc.id = icl.id)
  WHERE     sc.contract_date BETWEEN '2015-03-02'
                             AND     '2015-03-10'
  ORDER BY  sc.contract_number ASC;

我得到的结果是：

    id              | Contract Date |           Customer Name           | PMS             | New Amount | Renew Amount | Service Tax | Total

预期结果

    id              | Contract Date |           Customer Name           | PMS             | New Amount | Renew Amount | Service Tax | Total

您正在使用select pt…的输出。。。。作为列，请尝试在from子句中移动select，如下所示：

SELECT    (sc.contract_number) AS id,
            to_char(sc.contract_date, 'DD/MM/YYYY') AS "Contract Date",
            (sc.cust_name) AS "Customer Name",
            pt.product_desc AS "PMS",
            CASE WHEN sc.parent_ref IS NULL THEN ROUND(sc.basic_amount)
                 ELSE 0
            END AS "New Amount",
            CASE WHEN sc.parent_ref IS NULL THEN 0
                 ELSE ROUND(sc.basic_amount)
            END AS "Renew Amount",
            ROUND(sc.service_tax_amount + sc.edu_tax_amount +
                  sc.hs_edu_tax_amount) AS "Service Tax",
            ROUND(sc.grand_total_amount) AS "Total"
  FROM      product_product pp, product_template pt, sale_contract sc
  INNER JOIN inspection_costing_line icl ON (sc.id = icl.id)
  WHERE     sc.contract_date BETWEEN '2015-03-02'
                             AND     '2015-03-10' and
            pt.id = pp.product_tmpl_id AND
            type = 'service' AND
            pt.name LIKE sc.pms_lines
  ORDER BY  sc.contract_number ASC;

我无法对其进行测试，但可以将其用作起点

您可以演示如何加入销售和发票表吗？这是我的查询。。从sc.id=icl.id上的销售合同sc内部连接检验成本计算行icl中选择列名称，其中sc.contract日期在“2015-03-02”和“2015-03-10”之间，由sc.contract\U编号ASC确定@abhijeetmote。使用您正在使用的真实查询编辑您的问题。评论中的版本不是您正在运行的版本-例如，它只会返回一列。我从您的问题中删除了所有的和HTML，但却被还原回：“很抱歉，这是问题中的最终更改…使用您的解决方案，将跳过包含多个PM的记录，据我所知，子查询工作正常。。。问题在于连接。
