游标将值存储在变量中但未在另一个 table Sql 服务器中更新

Question

我写了一个游标，我在其中使用游标从 table 获取值并在另一个 table 中更新这些值。在测试时，我分析了值存储在 table 中并且更新也在工作，因为 sql 服务器消息显示 1 行已更新，但游标中的值未在 table 我很困惑，无法得到任何答案

我不清楚您遇到问题的原因，但这确实不需要游标（几乎什么都不需要，除了一些非常小众的场景，它们速度慢且难以编码）。

你可以直接加入更新

UPDATE pp
SET
    PATIENT_TOTAL_BAL = pae.PATIENT_TOTAL_BAL, 
    INS_TOTAL_BAL = pae.INS_TOTAL_BAL,
    PATIENT_CURRENT_AMT_DUE = pae.PAT_CURRENT_AMOUNT, 
    ABOVE_30 = pae.PAT_ABOVE_30, 
    ABOVE_60 = pae.PAT_ABOVE_60, 
    ABOVE_90 = pae.PAT_ABOVE_90, 
    ABOVE_120 = 5000, 
    INS_CURRENT_AMT_DUE = pae.INS_CURRENT_AMOUNT, 
    INS_ABOVE_30 = pae.INS_ABOVE_30, 
    INS_ABOVE_60 = pae.INS_ABOVE_60, 
    INS_ABOVE_90 = pae.INS_ABOVE_90, 
    INS_ABOVE_120 = pae.INS_ABOVE_120
FROM PATIENT_PROF pp
JOIN T_PATIENT_AMOUNT_AGE pae ON pae.patient_seq_num = pp.SEQ_NUM
WHERE pp.SEQ_NUM = 4366999;

你可以去掉WHERE到运行这个整体table。
