SELECT ROLL_PLAN_NO,NOM_ROLL_THICK,NOM_ROLL_WIDTH,NOM_SLAB_WIDTH,LG_ST,COUNT(*) AS NUM , SUM(CASE WHEN FILL_REASON=' ' THEN 1 ELSE 0 END) 正常計劃, SUM(CASE WHEN FILL_REASON='1' THEN 1 ELSE 0 END) 無委, SUM(CASE WHEN FILL_REASON='2' THEN 1 ELSE 0 END) 填充 FROM HPMOMMA00 WHERE ROLL_PLAN_NO='112076' GROUP BY ROLL_PLAN_NO,NOM_ROLL_THICK,NOM_ROLL_WIDTH,NOM_SLAB_WIDTH,LG_ST UNION ALL SELECT ROLL_PLAN_NO,NOM_ROLL_THICK,NOM_ROLL_WIDTH,NOM_SLAB_WIDTH,LG_ST,COUNT(*) AS NUM, SUM(CASE WHEN FILL_REASON=' ' THEN 1 ELSE 0 END) 正常計劃, SUM(CASE WHEN FILL_REASON='1' THEN 1 ELSE 0 END) 無委, SUM(CASE WHEN FILL_REASON='2' THEN 1 ELSE 0 END) 填充 FROM TPMOMMA00 WHERE ROLL_PLAN_NO='112076' GROUP BY ROLL_PLAN_NO,NOM_ROLL_THICK,NOM_ROLL_WIDTH,NOM_SLAB_WIDTH,LG_ST
SELECT NVL(SUM(NOM_SLAB_WT),0) FROM TPMOMMA00 WHERE ORDER_NO='"+order_no+"' AND APP_STATUS<='64' AND FILL_REASON='2'
這個NVL函式是若查出來為NULL則為0,前面是case when實用統計
