How do I add a table element without changing grouping? This select works as intended:
SELECT cid, cnumber, cenrtyp, MAX(nqpoints);
from demographicenroll3.dbf;
WHERE cenrtyp = "RT" ;
GROUP BY cid, cnumber, cenrtyp ;
This gives me a list which includes only one of the records in the group cid, subgroup cnumber, that has the max nqpoints value, which is what I want.
But I need to include the unique record number of cnumber in my recordset, which is ecid - so I add ecid:
SELECT cid, cnumber, cenrtyp, MAX(nqpoints), ecid;
from demographicenroll3.dbf;
WHERE cenrtyp = "RT" ;
GROUP BY cid, cnumber, cenrtyp, ecid ;
But this doesn't work because it changes the grouping making the Max(nqpoints) incorrect. Any tricks to get what I want?
You can't do that in a single query, but you can by making your existing query into a derived table in another query:
SELECT dmax.cid, dmax.cnumber, dmax.cenrtyp, maxpts, ecid ;
FROM demographicenroll3 d3
JOIN (
SELECT cid, cnumber, cenrtyp, MAX(nqpoints) AS maxpts;
from demographicenroll3;
WHERE cenrtyp = "RT" ;
GROUP BY cid, cnumber, cenrtyp) dmax ;
ON d3.cid = dmax.cid ;
AND d3.cnumber = dmax.cnumber ;
AND d3.cenrtyp = dmax.cenrtype ;
AND d3.nqpoints = dmax.maxpts

Is it possible to rewrite the following query
SELECT CT.GROUP, CT.EMP_ID, HT.EFF_DT
FROM CURR_TABLE CT
JOIN (SELECT GROUP, EMP_ID, MAX(EFF_DT) AS EFF_DT
FROM HIST_TABLE
WHERE STAT = 'A'
GROUP BY GROUP, EMP_ID) HT ON CT.GROUP = HT.GROUP AND
CT.EMPID = HT.EMP_ID
WHERE CT.GROUP = :1
AND CT.EMP_ID = :2
in a way that is similar to CROSS JOIN style?
SELECT table1.column1, table2.column2...
FROM table1, table2 [, table3 ]
The reason is that I want to create such query in Peoplesoft, and the above can only be achieved by creating a separate view for the selection with the group by clause. I want to do this just in one query without creating additional views.
You may try writing your query as a single level join with an aggregation:
SELECT
CT.GROUP,
CT.EMP_ID,
MAX(HT.EFF_DT) AS EFF_DT
FROM CURR_TABLE CT
LEFT JOIN HIST_TABLE HT
ON CT.GROUP = HT.GROUP AND
CT.EMPID = HT.EMP_ID AND
HT.STAT = 'A'
WHERE
CT.GROUP = :1 AND
CT.EMP_ID = :2
GROUP BY
CT.GROUP,
CT.EMP_ID;
Note that GROUP is a reserved SQL keyword, and you might have to escape it with double quotes to make this query (or the one in your question) work on Oracle.
I am new to Oracle. I am trying to update the values of a table with the values from a SELECT DISTINCT statement using the MERGE INTO method. I want to update the values for a table based on what is in the USING table conditionally.
A quick diagram of what I am essentially going for is
MERGE
INTO update_table ut
USING
(SELECT DISTINCT
t1.column_1
,t2.column_2
FROM table_1 t1
INNER JOIN table_2 t2
ON t1.foreign_key = t2.primary_key) st
ON (ut.pk = st.column_1)
WHEN MATCH UPATE
SET(ut.update_column = st.column_2
WHERE st.column_1 = 1
AND st.column_2 = 1
,ut.update_column = st.column_2
WHERE st.column_1 = 2
AND st.column_2 = 2);
However, when I do so I get the INVALID COLUMN SPECIFICATION error on the line where I use SET. How can I work around this to successfully update the table, preferably in ANSI standard?
You can include the conditions that you have added in where clause in the selected column list in using clause itself. Like This. (Not tested. Your conditions in where clause were not appropriate)
MERGE
INTO update_table ut
USING (SELECT DISTINCT
t1.column_1 ,
CASE
WHEN t1.column_1 = 1
AND t2.column_2 = 1
THEN t2.column_1
WHEN t1.column_1 = 2
AND t2.column_2 = 2
THEN t2.column_2
END column_2
FROM
table_1 t1
INNER JOIN table_2 t2 ON t1.foreign_key = t2.primary_key
) st
ON (ut.pk = st.column_1)
WHEN MATCHED THEN
UPDATE SET ut.update_column = st.column_2 ;
I have a query that I need for it to return a record even when there are no records. In the case where there are records, I simply want those records returned. On the other hand, when there are no records, I need it to still return a record but with the value for the "context" column (the GROUP BY column) equal to the value of the GROUP BY column that did not meet the criteria and a default value for aggregate function/column (e.g., 0). I tried a subquery:
SELECT
(
SELECT
CONTEXT,
SUM(VAL)
FROM
A_TABLE
WHERE
COL = 'absent'
GROUP BY
CONTEXT
)
FROM
DUAL;
but anything greater than one column in the subquery SELECT clause fails w/ a "too many values" message.
I also tried a UNION (with a little more context to more faithfully represent my situation):
SELECT
*
FROM
(
SELECT
CONTEXT,
SUM(VAL)
FROM
A_TABLE
WHERE
COL = 'absent'
GROUP BY
CONTEXT
UNION
SELECT
CONTEXT,
0
FROM
B_TABLE
)
AB_TABLE
INNER JOIN C_TABLE C -- just a table that I need to join to
ON
C.ID = AB_TABLE.C_ID
WHERE
C.ID = 10
AND ROWNUM = 1 -- excludes 2nd UNION subquery result when 1st returns record;
This one does work but I don't know why since the 2nd UNION subquery does not seem to be expressly connected w/ the first (I need the 2nd CONTEXT value to be the same as the 1st for the case where the 1st returns no records). The problem is that the real query does not return any records when I try to implement a similar strategy. I would like to see if there's a better way to approach this problem and perhaps get it to work for the real query (not included as it is too large and somewhat sensitive).
I am not sure I understand the question, but let's try.
I believe what you are saying is this. You have a table called A_TABLE, with columns CONTEXT, VAL, COL (and perhaps others as well).
You want to group by CONTEXT, and get the sum of VAL but only for those rows where COL = 'absent'. Otherwise you want to return a default value (let's say 0).
This can be done with conditional aggregation. The condition is in a CASE expression within the SUM, not in a WHERE clause (as you saw already, if you filter by COL='absent', in a WHERE clause, the query - past the WHERE clause - has no knowledge of the CONTEXT values that don't appear in any rows with COL = 'absent').
If the "default value" was NULL, you could do it like this:
select context, sum(case when col = 'absent' then value end) as val
from a_table
group by context
;
If the default value is anything other than NULL, the temptation may be to use NVL() around the sum. However, if VAL may be NULL, then it is possible that SUM(VAL) is NULL even when there are rows with COL = 'absent'. To address that possibility, you must leave the sum as NULL in those cases, and instead set the value to 0 (or whatever other "default value") only when there are NO rows with COL = 'absent'. Here is one way to do that. Still a standard "conditional" aggregate query:
select context,
case when count(case when col = 'absent' then 1 end) > 0
then sum(case when col = 'absent' then value end)
else 0 -- or whatever "default value" you must assign here
end as val
from a_table
group by context
;
Here's another way you could handle it that avoids the two additional tables (B_TABLE and C_TABLE).
SELECT context
, MAX(val)
FROM (
SELECT context
, SUM(val) as val
FROM a_table
WHERE col = 'absent'
GROUP BY context
UNION
SELECT context
, 0 as val
FROM a_table
) t
GROUP BY context
This assumes the default value you want to return is 0 and that any value in A_TABLE.VAL will be a positive integer.
http://sqlfiddle.com/#!4/c6ca0/20
SELECT b.context
, sum(a.val)
FROM b_table b
LEFT OUTER JOIN a_table a
ON a.context = b.context
AND a.col = 'absent'
GROUP BY b.context

You have this expression among the select columns (at the top of your code):
(Select 'Y' from MBR_ERR t7 where t7.Member_ID = t6.Member_ID
and t7.Rundate = &Mbr_Err_RunDate ) Mbr_Err
If you want to select the literal 'Y', then just select 'Y' as Mbr_Err. If you want to select either 'Y' or null, depending on whether the the subquery returns exactly one row or zero rows, then write it that way.
I suspect this subquery (or perhaps another one in your code, used in a similar way) returns more than one row - in which case you will get exactly the error you got.
I need to write a dynamic query inside In clause of pivot query in oracle 11g. With Pivot xml, it is possible, but I do not need the xml one. Here is the code snippet.
WITH pivot_data AS (
