Execute immediate v_SQL;
where v_FY0 is NUMBER(10);v_SQL NVarchar2(4000),v_InsertType VARCHAR2(4000); and v_OffSet Number(10); v_tblInsertType VARCHAR2(4000);
Upon executing, I get: v_FY0 =2018 and v_OffSet = 0;
Upon executing ,i am getting the error - ORA-00923: FROM Keyword not found where expected.
How to resolve this issue and how to get this working.
You can't use as in the from clause.
This query:
select * from (select dummy from dual) as tab
produces error ORA-00933. So simply remove as:
select * from (select dummy from dual) tab

my display cade looks like below i want to covert my display from vertical to horizontal
code:-
dbms_output.put_line('output1 : ' || value1);
dbms_output.put_line('output2 : ' || value2);
dbms_output.put_line('output3 : ' || value3);
dbms_output.put_line('output4 : ' || value4);
dbms_output.put_line('output5 : ' || value5);
dbms_output.put_line('output6 : ' || value6);
output:-
output1 : 100
output2 : 200
output3 : 300
output4 : 400
output5 : 500
output6 : 600
I want output like below:-
output1 output2 output3 output4 output5 output6
100 200 300 400 500 600
As a first step, you will need to assign rows to the columns
select output1,output2,....., row_number() over (partition by value1 ,....order by output) col from yourtable
then you add PIVOT:
PIVOT
(
max(output)
for col in (1, 2, 3, ..., 240)
)```
You can use LPAD:
DECLARE
value1 NUMBER(8,2) := 100;
value2 NUMBER(8,2) := 200;
value3 NUMBER(8,2) := 300;
value4 NUMBER(8,2) := 400;
value5 NUMBER(8,2) := 500;
value6 NUMBER(8,2) := 600;
c_width CONSTANT PLS_INTEGER := 10;
BEGIN
dbms_output.put_line(
LPAD('output1', c_width, ' ')
|| ' ' || LPAD('output2', c_width, ' ')
|| ' ' || LPAD('output3', c_width, ' ')
|| ' ' || LPAD('output4', c_width, ' ')
|| ' ' || LPAD('output5', c_width, ' ')
|| ' ' || LPAD('output6', c_width, ' ')
);
dbms_output.put_line(
LPAD(value1, c_width, ' ')
|| ' ' || LPAD(value2, c_width, ' ')
|| ' ' || LPAD(value3, c_width, ' ')
|| ' ' || LPAD(value4, c_width, ' ')
|| ' ' || LPAD(value5, c_width, ' ')
|| ' ' || LPAD(value6, c_width, ' ')
);
END;
/
Which outputs:
output1 output2 output3 output4 output5 output6
100 200 300 400 500 600
or TO_CHAR:
DECLARE
value1 NUMBER(8,2) := 100;
value2 NUMBER(8,2) := 200;
value3 NUMBER(8,2) := 300;
value4 NUMBER(8,2) := 400;
value5 NUMBER(8,2) := 500;

I want to write dynamic query from update statement to merge merge statement

this one also not work ----ORA-01747: invalid user.table.column, table.column, or column specification
dynamic update to dynamic merge
while changing merge with update statement
not working
There are few mistakes in concatenation and usage of the MERGE statement.
Try the following dynamic query:
'MERGE INTO '
|| TABLE1
|| ' t1 '
|| ' USING '
|| TABLE2
|| ' t2 '
|| ' ON ( '
|| V_CONS
|| ' ) when matched then update set '
|| REGEXP_SUBSTR(V_T1_FIELDS, '[^,]+', 1, 1)
|| ' = '
|| REGEXP_SUBSTR(V_T2_FIELDS, '[^,]+', 1, 1)
|| ', '
|| REGEXP_SUBSTR(V_T1_FIELDS, '[^,]+', 1, 2)
|| ' = '
|| REGEXP_SUBSTR(V_T2_FIELDS, '[^,]+', 1, 2)
|| ', '
|| REGEXP_SUBSTR(V_T1_FIELDS, '[^,]+', 1, 3)
|| ' = '
|| REGEXP_SUBSTR(V_T2_FIELDS, '[^,]+', 1, 3);
I am assuming that
TABLE1 and TABLE2 are valid table names
V_CONS is a valid condition on tables
V_T1_FIELDS and V_T2_FIELDS contains valid column names of the table

commit;
n_cnt := n_cnt + 1;
end loop;
The issue is here:
. . . || to_char(i.order_date,'yyyymmdd') + 1 ||
Which is currently seen as:
(. . . || to_char(i.order_date,'yyyymmdd')) + 1 ||
The implicit number conversion fails for the above and hence the error.
Enclose the addition to_char(i.order_date,'yyyymmdd') + 1 inside parentheses:
dbms_output.put_line(n_cnt ||'--'|| to_char(sysdate,'yyyymmdd') ||'--'|| chr(1) || '43' ||'--'||
chr(1) || n_dealer ||'--'|| '1525' ||'--'|| '0' ||'--'|| i.amount ||'--'||
chr(1) || i.product_id ||'--'|| chr(1) || i.quantity ||'--'||
chr(1) || (to_char(i.order_date,'yyyymmdd') + 1) ||'--'|| chr(1) ||
to_char(i.order_date,'yyyymmdd'));
EDIT:
As noted by Wernfried, there is another problem in your code. You should add 1 to the date, not the result string.
So correct code will be:
inside parentheses:
dbms_output.put_line(n_cnt ||'--'|| to_char(sysdate,'yyyymmdd') ||'--'|| chr(1) || '43' ||'--'||
chr(1) || n_dealer ||'--'|| '1525' ||'--'|| '0' ||'--'|| i.amount ||'--'||
chr(1) || i.product_id ||'--'|| chr(1) || i.quantity ||'--'||
chr(1) || to_char(i.order_date + 1,'yyyymmdd') ||'--'|| chr(1) ||
to_char(i.order_date,'yyyymmdd'));
I have an elasticsearch cluster containing 10 nodes splited across 3 zones (A, B, C).
The ES configuration file contain:
cluster.routing.allocation.awareness.force.zone.values = "A,B,C";
I have a single index (index1) containing =~ 283674 docs with a size of =~ 231MB.
The setting for this index contain:
"number_of_replicas" : "2", "number_of_shards" : "5",
Shards seems correctly distributed across zone but within a single zone they are not evenly distributed (see table below, E.g. Zone C | S = shard, (P = Primary | S = Secondary)
What can I do to correctly distribute my shards?
++------+----------------------------------------------------+
||Zone A-----------------------------------------------------|
|| | ||
|| Node 1| S1 (P) ||
|| +-----------------------------------------------------+ ||
|| | ||
|| | S2 (S) S4 (S) ||
|| | ||
|| Node 2| ||
|| +-----------------------------------------------------+ ||
|| | ||
|| | ||
|| | S0 (S) S3 (S) ||
|| | ||
|| Node 3| ||
|-------+----------------------------------------------------|
||Zone B-----------------------------------------------------|
|| | ||
|| | S0 (P) ||
|| Node 4| ||
|| +-----------------------------------------------------+ ||
|| | ||
|| | ||
|| | S3 (P) S4 (P) ||

|| | ||
|| | ||

|| Node 10 ||
|------------------------------------------------------------|
+------------------------------------------------------------+
I fixed the issue by forcing the number of shard per host and changing the number of primary / secondary per index:
index.number_of_shards = "5";
index.number_of_replicas = "3";
index.routing.allocation.total_shards_per_node = "2";
This results in 2 shards per node evenly distributed across zone.

However, I am getting the following error:
Error report:
ORA-01410: invalid ROWID
ORA-06512: at line 13
01410. 00000 - "invalid ROWID"
*Cause:
*Action:
1 Ramesh 32
2 Khilan 25
3 kaushik 23
4 Chaitali 25
5 Hardik 27
6 Komal 22
Why is this happening and how can I stop it?
You have your exit in the wrong place; it should be straight after the fetch. You are processing your six real rows properly, but then you have a seventh fetch - after which %notfound will be true - so there is no 'current' row to update. You need to exit before you try to do anything with that invalid row.
BEGIN
OPEN c1;
LOOP
FETCH c1 INTO c_id, c_name, c_age;
EXIT WHEN c1%NOTFOUND;
UPDATE customers
SET age = age + 1
WHERE CURRENT OF c1;
dbms_output.put_line( c_id || ' ' || c_name || ' ' || c_age );
END LOOP;
CLOSE c1;
END;
Hopefully this is just an exercise, as it's not a very efficient way to do the updates.
