您可以将其拆分为您为其创建视图的逻辑组件。

例如 :

  LEFT JOIN
    (SELECT dtl.txde_sku_code sku_code , COALESCE( SUM(hdr.txhd_value_nett), 0) txn_sales FROM txn_detail dtl
    JOIN txn_header hdr ON dtl.orgu_code_cmpy      = hdr.orgu_code_cmpy AND dtl.orgu_code = hdr.orgu_code AND
      dtl.till_short_desc                          = hdr.till_short_desc AND dtl.txhd_txn_nr = hdr.txhd_txn_nr
    JOIN txn_header_wag txhw ON hdr.orgu_code_cmpy = txhw.orgu_code_cmpy AND hdr.orgu_code = txhw.orgu_code AND
      hdr.till_short_desc                          = txhw.till_short_desc AND hdr.txhd_txn_nr = txhw.txhd_txn_nr
    WHERE hdr.txhd_txn_type                        = 10
    AND dtl.txde_detail_type                      IN ( '1', '2', '3', '201', '202', '203', '204', '205', '206',
      '207', '208', '210', '211' )
    AND txhw.txhw_processed_date = '20111212'
    AND hdr.txhd_state           = 0
    AND hdr.txhd_training_mode   = 0
    AND hdr.txhd_voided          = 0
    AND dtl.txde_item_void       = 0
    GROUP BY dtl.txde_sku_code
    ) txn ON prd.prod_sku = txn.sku_code

可以替换为:

CREATE OR REPLACE VIEW sum_sales_by_date_sku_code 
AS
SELECT txhw.txhw_processed_date processed_date,dtl.txde_sku_code sku_code , COALESCE( SUM(hdr.txhd_value_nett), 0) txn_sales FROM txn_detail dtl
    JOIN txn_header hdr ON dtl.orgu_code_cmpy      = hdr.orgu_code_cmpy AND dtl.orgu_code = hdr.orgu_code AND
      dtl.till_short_desc                          = hdr.till_short_desc AND dtl.txhd_txn_nr = hdr.txhd_txn_nr
    JOIN txn_header_wag txhw ON hdr.orgu_code_cmpy = txhw.orgu_code_cmpy AND hdr.orgu_code = txhw.orgu_code AND
      hdr.till_short_desc                          = txhw.till_short_desc AND hdr.txhd_txn_nr = txhw.txhd_txn_nr
    WHERE hdr.txhd_txn_type                        = 10
    AND dtl.txde_detail_type                      IN ( '1', '2', '3', '201', '202', '203', '204', '205', '206',
      '207', '208', '210', '211' )
AND hdr.txhd_state           = 0
AND hdr.txhd_training_mode   = 0
AND hdr.txhd_voided          = 0
AND dtl.txde_item_void       = 0
GROUP BY dtl.txde_sku_code;

查询部分将更改为:

 LEFT JOIN sum_sales_by_sku_code  tnx ON prd.prod_sku = txn.sku_code
 WHERE tnx.processed_date = '20111212'
