在子查询中使用带有过滤器的子查询进行选择

Question

我有以下代码：

SELECT DISTINCT    
    tctc_cntipcli as "Type of contract" ,
    texe_cncclipu as "Contract number",
    TCTC_CNDOCIDC as "Client name", 
    tsrv_cndesser as "Service name", 
    texe_cnfuncid as "Service number", 
    tsrs_cnsubsdc as "Subservice name", 
    texe_cnsubser as "Subservice number", 
    tmap_cndesc as "Map",

    ( 
        SELECT to_char(count(tlof_cnlofrid)) 
        from service.kndtlof
        where   
            tlof_cncclipu = tctc_cncclipu and
            tlof_cnservic = texe_cnfuncid and
            tlof_cnsubser = texe_cnsubser and
            tlof_cnfhalta > trunc (sysdate, 'mm')
    ) as "Volume of files messages" ,
    (
        select count(it.int_tran_id)
        from internal_transactions it
        join status ss on ss.int_tran_id = it.int_tran_id
        join app_data ad on it.int_tran_id in 
        (
            select distinct ad.int_tran_id
            from app_data
            where app_data.add_info_table in ('ACH', 'Wire')
        )
        join service.kndtexe ke on it.debit_acct in 
        (
            select distinct texe_cnasupro
            from service.kndtexe ke
            where 
                (
                    (ke.texe_cnfuncid = '3001' and ke.texe_cnsubser = 'W1')
                    or
                    (ke.texe_cnfuncid = '3085' and ke.texe_cnsubser = 'I%')
                )
        )
        where it.entry_timestamp > trunc(sysdate, 'mm')
    ) as "Volume of payments"
from 
    service.kndtctc, 
    service.kndtexe, 
    service.kndtscm, 
    service.kndtsrv, 
    service.kndtsrs, 
    service.kndtmap
where 
    tctc_cncclipu = texe_cncclipu
    and texe_cnfuncid = tsrv_cncveser
    and texe_cnfuncid = tsrs_cncveser 
    and texe_cnsubser = tsrs_cnsubser
    and texe_cncclipu = tscm_cncontra
    and tscm_cnmapco = tmap_cnmapco
    and tscm_cnservic = tsrv_cncveser
    and tscm_cnsubser = tsrs_cnsubser
    and tctc_cnestado in ('01', '03')
    and texe_cnestado in ('01', '03')
    and tsrv_cnestado in ('01', '03')
    and tsrs_cnestado in ('01', '03')
    and tscm_cnestado in ('01', '03')
    and tmap_cnestado in ('01', '03')
    and tctc_cncclipu in ('50008753')
order by tctc_cncclipu;

第二个子查询是从事务 db 查询到服务 db（请参阅业务需求图像），需要检查 texe 表中是否存在与 tctc 中的合同编号下的合同相关联的任何帐户，并且仅输出 3001 /W1 或 3085/I%。我如何过滤子查询来实现这一点？

您可以使用

将查询放置在查询周围
