Question

所以我有我的proc的这一部分：

SELECT
        com_contact.rc_name_full as CreatedBy,
        capComponent.cm_strike as CapStrike,
        floorComponent.cm_strike as FloorStrike,
        tq_nominal_notional as Notional,
        maxComponent.cm_effective_dt as EffectiveDate,
        maxComponent.cm_maturity_dt as MaturityDate,
        CAST(CAST(DATEDIFF(mm,maxComponent.cm_effective_dt,maxComponent.cm_maturity_dt) as decimal(9,2))/12 as decimal(9,2)) as term,
        (
            CASE WHEN se_amort_term_mnth IS NOT NULL THEN se_amort_term_mnth / 12
            ELSE CAST(CAST(DATEDIFF(mm,
                ISNULL(cmam_amortization_start_dt, maxComponent.cm_effective_dt),
                cmam_amortization_end_dt) as decimal(9,2))/12 as decimal(9,2))
            END
        ) AS AmortTermYears,
        tq_dd_product as Product,
        dh_key_rate as KeyRate,
        dh_pv01 as PV01,
        dh_val_time_stamp as RateTimeStamp,
        re_bnk_le.re_company_name as Company,
        rc_contact_id as UserId,
        stp_name as NickName,
        '' as project,
        '' as Borrower,
        '' as Lender,
        '' as AdditionalInfo,
        CASE WHEN tpm_pd_permission_id = 85 THEN 'LLH' WHEN tpm_pd_permission_id = 86 THEN 'ALM' ELSE '' END as Permission,
        tr_transaction_id as TransactionId,
        NULL as IndicationId

    FROM cfo_transaction

显示'' as project的行，我们现在必须实际更改以返回数据。

名为FROM的{{1}}旁边的表格上有一个名为cfo_transaction的ID。我们有另一个名为tr_transaction_id的表，它将这些id与项目ID相关联，使用两个名为：

的列。

com_project_transaction_link和pt_tr_transaction_id，然后我们有一个表格，其中包含名为pt_pj_project_id且com_project和pj_project_id的所有项目。

目标：从该项目表中返回pj_project_name，并将其与正在拉动的交易相关联。

我真的不知道该怎么做。

谢谢！

Answer 1

您只需向查询的另一个表添加第二个联接。

select 
    yourfields,
    p.pj_project_name as project
FROM cfo_transaction t
join com_project_transaction_link tl
  on t.tr_transaction_id = tl.pt_tr_transaction_id
join com_project p
  on tl.pt_pj_project_id = p.pj_project_id

Answer 2

SELECT ..., cp.pj_project_name
    FROM cfo_transaction ct
        INNER JOIN com_project_transaction_link cptl
            ON ct.tr_transaction_id = cptl.pt_tr_transaction_id
        INNER JOIN com_project cp
            ON cptl.pt_pj_project_id = cp.pj_project_id

Answer 3

试试这个：

SELECT
        com_contact.rc_name_full as CreatedBy,
        capComponent.cm_strike as CapStrike,
        floorComponent.cm_strike as FloorStrike,
        tq_nominal_notional as Notional,
        maxComponent.cm_effective_dt as EffectiveDate,
        maxComponent.cm_maturity_dt as MaturityDate,
        CAST(CAST(DATEDIFF(mm,maxComponent.cm_effective_dt,maxComponent.cm_maturity_dt) as decimal(9,2))/12 as decimal(9,2)) as term,
        (
            CASE WHEN se_amort_term_mnth IS NOT NULL THEN se_amort_term_mnth / 12
            ELSE CAST(CAST(DATEDIFF(mm,
                ISNULL(cmam_amortization_start_dt, maxComponent.cm_effective_dt),
                cmam_amortization_end_dt) as decimal(9,2))/12 as decimal(9,2))
            END
        ) AS AmortTermYears,
        tq_dd_product as Product,
        dh_key_rate as KeyRate,
        dh_pv01 as PV01,
        dh_val_time_stamp as RateTimeStamp,
        re_bnk_le.re_company_name as Company,
        rc_contact_id as UserId,
        stp_name as NickName,
        PR.pj_project_name as project,
        '' as Borrower,
        '' as Lender,
        '' as AdditionalInfo,
        CASE WHEN tpm_pd_permission_id = 85 THEN 'LLH' WHEN tpm_pd_permission_id = 86 THEN 'ALM' ELSE '' END as Permission,
        tr_transaction_id as TransactionId,
        NULL as IndicationId

    FROM cfo_transaction TR
    INNER JOIN com_project_transaction_link TL
    ON TR.tr_transaction_id = TL.pt_tr_transaction_id
    INNER JOIN com_project PR
    ON TL.pt_pj_project_id = PR.pj_project_id

上面的查询假设每个事务和项目都在加入项目和事务表的表上（因此INNER JOIN），但是如果你想要，你可以将它们改为LEFT JOIN
