我有VP3 - 艺术与设计和HS5 - 健康与社会关怀,我需要在Oracle之后获得字符串' - '.这可以使用子串实现吗？

谢谢,Ar

我需要在sql中将yyyy-mm-dd hh:mm:ss.msec转换为yyyy-mm-dd.

我试过了

CONVERT(DATETIME,MIN(Vdaily_calender.VDC_day_date),120)

但得到相同的结果.

请指教

谢谢Ar

我正在尝试连接到Datasource,但收到此错误:

An error occurred during local report processing. 
An error has occurred during report processing. 
Cannot create a connection to data source 'PO'.
You have specified integrated security or credentials in the connection string for the data source, but the data source is configured to use a different credential type. To use the values in the connection string, you must configure the unattended report processing account for the report server.

知道如何解决这个问题吗？

谢谢Aruna

我试图在Oracle中执行以下查询:

SELECT DISTINCT
   t4.s_studentreference "Student ID",
  t3.p_surname "Surname",
  t3.p_forenames "Forenames",
t1.m_reference "Course",
 t2.e_name "Enrolment Name"
 FROM student t4,
  person t3,
  enrolment t2,
  course t1
WHERE t4.s_id(+) =t3.p_id
AND (t2.e_student=t3.p_id)
AND (t2.e_course =t1.m_id)
AND (t1.m_reference LIKE 'LL563%15')
OR (t1.m_reference LIKE 'LL562%15')
OR (t1.m_reference LIKE 'LL563%16')
OR (t1.m_reference LIKE 'LL562%16')

但是,我得到以下错误:

ORA-01652: unable to extend temp segment by 128 in tablespace TEMP
01652. 00000 -  "unable to extend temp segment by %s in tablespace %s"
*Cause:    Failed to allocate an extent of …

我在SQL Server上执行以下查询，但出现错误：

SELECT DISTINCT t1.p_id "Id",
(TO_CHAR("sysdate", 'YYYY') + least(SIGN(("sysdate" - to_date('01-Aug-' | | TO_CHAR("sysdate", 'YYYY'), 'DD-Mon-RRRR'))), 0)) "Year"

FROM 
   t1,
   t7,
   t9
WHERE 
   t9.ei_id(+)          = t7.e_id
AND (t7.e_student        = t1.p_id)
AND (t7.e_module         = t8.m_id)
AND (NVL(t9.ei_q18m06, t7.e_end) > '31-Jul-' | | (TO_CHAR("sysdate", 'YYYY') + least(SIGN(("sysdate" - to_date('01-Aug-' | | TO_CHAR("sysdate", 'YYYY'), 'DD-Mon-RRRR'))), 0) + - 5))

Error:

'nvl' is not a recognized built-in function name. 

知道如何避免这种情况吗？

我在server1上有原始查询，需要在服务器2上创建它。我能够创建View，但是在执行该视图时，在CASE语句中遇到错误，如下所示：

Error:

    Msg 8180, Level 16, State 1, Line 1
    Statement(s) could not be prepared.
    Msg 102, Level 15, State 1, Line 1
    Incorrect syntax near 'Qry1097'.
    Msg 125, Level 15, State 4, Line 1
    Case expressions may only be nested to level 10.

查询：SELECT

ID, Forename, Surname, 

Code, Description, 

Grade, Dept,

Course, Title, 

CASE WHEN Code IN ('VJ028') THEN 'FUNCTIONAL SKILLS - LEVEL 1 & LEVEL 2' 

WHEN Code IN ('VE203', '22877C')  THEN 'WRITING - LEVEL 2' 

WHEN Code …

    (to_char(sysdate,'YYYY')+least(sign((sysdate-to_date('01-Aug-'||
to_char(sysdate,'YYYY'),'DD-Mon-RRRR'))),0)) "AcYear"

错误：

'to_char' is not a recognized built-in function name.

我尝试将 to_char 和 to_date 更改为 CONVERT 但出现错误。

我期待 2016 年 AcYear

有人可以帮忙吗？
