Counting chars in sequences via SQL
(2 answers)
Closed 7 years ago.
In Postgres/SQL, how can I get the count of a character in a column?
For example, I want to run a query which will return the number of times "X" appears in a column that has the value "XXX" - and it should return 3.
One method is the difference of lengths:
select (length(col) - length(replace(col, 'X', ''))) as NumX

I want to get the person number and phase against max sequence phase for the employee -
PERSON_NUMBER
SEQUENCE
Phase Name

Which function can I use in OTBI for this ? I tried using
"max("Job Application - Progression"."Current Phase Sequence Number") keep(dense_rank first order by "Job Application - Progression"."Current Phase Name" desc)"
But this is not the correct syntax for OTBI

Query to get multiple row into single row
(3 answers)
Closed 3 years ago.
I have the below data and I have to concatenate the long text column and make it as a single row. The challenge part is only one row has the notification number and other rows are null. You cannot group by the notification number.
I need the output as 2 rows
row number Notification Number Plant Creation Date Language Lineno Tag Long Text
1 10014354914 A057 43466 EN 1 >X aaabbbcccdddeeefffggghhhjjjkkklll
2 10014354915 A057 43466 EN 1 >X aaabbbcccdddeeefffgggpppqqqrrrsss
I have used cursor for this. But it is taking much time.
If you are using oracle:
with data("row number", "Notification Number","Plant","Creation Date","Language","Lineno","Tag","Long Text") as (
select 1,10014354914,'A057',43466,'EN',1,'>X','aaabbbcccdddeeefffggghhhjjjkkklll' from dual
union all
select 2,10014354915,'A057',43466,'EN',1,'>X','aaabbbcccdddeeefffgggpppqqqrrrsss' from dual)
select LISTAGG("Long Text",'') within group (order by "row number") from data;
if you are using ms-sql maybe try this:
SELECT u.[Long Text] AS [text()]
FROM yourtable u
ORDER BY u.[row number]
FOR XML PATH ('')

Is there any way to return 3 as a result of ((5168/2000) .
I'm using CEILING(5168/2000) to delete rows. Its returning 2. But I want 3.
So that loop execute for 3 times.
Is there any way to return 3 as a result of (5168/2000)
Yes, make sure you're diving floating point numbers not integers
CEILING(5168.0/2000)
One way to achive that, aside from hardcoding the .0 as I have above, is to cast your integer to an appropriate type, for example:
CEILING(CAST(5168 AS FLOAT)/2000)
or muultiply it by a decimal
CEILING((1.0 * 5168)/2000)

How to get min/max of two integers in Postgres/SQL?
(2 answers)
Closed 6 years ago.
is there some way to determine the max value out of two values in SQL?
I use the mod function:
MOD(cnt, cnt/100)
This yields a division by 0 error when cnt is smaller than 100. I therefore would like something like this:
MOD(cnt, MAX(cnt/100, 1))
You can use greatest
SELECT greatest(a, b, c) FROM your_table;
