I need to format the resulted number after count it first
select
count(`mybooks.IDbook') as book
from mybooks
the query returns e.g. 3456
and I need to format is as 3.456
thank's
The following query will show your book count with decimal points as separators:
SELECT REPLACE(FORMAT(COUNT(0), 0), ',', '.') AS book
FROM mybooks
SQLFiddle
solved as
SELECT
REPLACE(FORMAT(COUNT(0), 0), ',', '.') AS books
FROM
mybooks
thank's for your time

I'm using the following code to convert a string datetime variable to datetime, but the converted string is missing SSS part.
Code used:
cast(FROM_UNIXTIME(UNIX_TIMESTAMP(oldtime, "yyyy-MM-dd'T'HH:mm:ss.SSS'Z'"),"yyyy-MM-dd HH:mm:ss.SSS") as timestamp) as newtime
The outcome:
2019-03-08T18:28:36.901Z is converted to 08MAR2019:18:28:36.000000
Some other oldtimes in string:
2020-03-09T16:05:06:827Z
2020-03-09T16:03:19:354Z
2020-03-11T16:03:57:280Z
2020-03-10T16:02:57:642Z
2020-03-10T16:04:07:455Z
2020-03-10T16:04:09:737Z
2020-03-10T16:03:57:280Z
2020-03-10T16:02:46:816Z
The SSS part '901' is missing in the converted time. Would like help on keeping the SSS part since I need to sort the records by their exact time.
Thank you!
from_unixtime is always until minutes(yyyy-MM-dd HH:mm:ss) to get millisecs we need to do some workarounds.
we will extract the millisecs from the old_time using regexp_extract then concat that to from_unixtime result and finally cast to timestamp.
Example:
select old_time,
timestamp(concat_ws(".", --concat_ws with . and cast
FROM_UNIXTIME(UNIX_TIMESTAMP(old_time, "yyyy-MM-dd'T'HH:mm:ss.SSS'Z'"),"yyyy-MM-dd HH:mm:ss"), -- from_unixtime and unix_timestamp to convert without millisecs
regexp_extract(string(old_time),".+\\.(.*)(?i)z",1))) as newtime from --regexp_extract to extract last 3 digits before z then concat
(select string("2020-03-11T21:14:41.335Z")old_time)e
+------------------------+-----------------------+
|old_time |newtime |
+------------------------+-----------------------+
|2020-03-11T21:14:41.335Z|2020-03-11 21:14:41.335|
+------------------------+-----------------------+
UPDATE:
Your sample data have : before milliseconds, Try with below query:
select old_time,
timestamp(concat_ws(".", --concat_ws with . and cast
FROM_UNIXTIME(UNIX_TIMESTAMP(old_time, "yyyy-MM-dd'T'HH:mm:ss:SSS'Z'"),"yyyy-MM-dd HH:mm:ss"), -- from_unixtime and unix_timestamp to convert without millisecs
regexp_extract(string(old_time),".+\\:(.*)(?i)z",1))) as newtime from --regexp_extract to extract last 3 digits before z then concat
(select string("2020-03-11T21:14:41:335Z")old_time)e
Simply replace 'T' with space ' ' remove 'Z' and replace last ':' with dot, like this :
select regexp_replace('2020-03-09T16:05:06:827Z','(.*?)T(.*?):([^:]*?)Z$','$1 $2\\.$3');
Result:
2020-03-09 16:05:06.827

I have a table in Oracle call STATISTICS.
COLUMN NAME DATE TYPE
MODEL VARCHAR2(30 BYTE)
NEW_COUNT NUMBER
NEW_DATE DATE
OLD_COUNT NUMBER
OLD_DATE DATE
PRNCT_CHANGE NUMBER
Now I have sql that updates statistics table:
UPDATE STATISTICS
SET
OLD_COUNT = NEW_COUNT,
NEW_COUNT =
( -- semantic table --
SELECT COUNT(*)
FROM TABLE(SEM_MATCH(
'{
?s ?p ?o
}',
SEM_Models(MODEL),NULL,
SEM_ALIASES(SEM_ALIAS('','http://SEMANTIC#')),NULL))
),
OLD_DATE = NEW_DATE,
NEW_DATE = SYSDATE
WHERE MODEL = &MY_MODEL
;
Now, can I do this? Push the date from a new date to an old date before I update the new date?
I am also doing the same thing with the NEW_COUNT and OLD_COUNT...
It sounded logical but is ok to do this?
So I followed my own advice :) and it worked just fine. I am not sure if this is the best practice but it does the trick
I have a table in sqlite db called [tblbook] with a column [authors]. What I am trying to do in the sql is to split the author values to firstname and the lastname and sort it on lastname. I did find this great code:
SELECT substr(BookAuthor, 1, NULLIF(CHARINDEX(' ', BookAuthor) - 1, -1)) AS [FirstName],
substr(BookAuthor, CHARINDEX(' ', BookAuthor) + 1, LEN(BookAuthor)) AS [LastName]
FROM tblBook where _id=3
It works perfectly on MSSQL but sqlite doesn't have the charindex function hence it fails.
Could anyone please be kind and advise me what should be the best approach to achieve this.
Another way (a little shorter) to write this would be
SELECT
substr(BookAuthor, 1, instr(BookAuthor, ' ') - 1) AS first_name,
substr(BookAuthor, instr(BookAuthor, ' ') + 1) AS last_name
FROM tblBook where id=3
ORDER BY last_name
This would apply for version 3.7.15 and beyond.
Unfortunately this functionality is missing from SQLite:

Index of substring in SQLite3?
Maybe you can feed your custom string position function to SQLite using http://www.sqlite.org/c3ref/create_function.html
But if you really need it, there is a complex, ineffective workaround:
http://sqlfiddle.com/#!7/e03a4/3
1: create a numbers table/view
2: join authors to numbers table, and choose the MIN position of the space
3: now you can split the names
SELECT
substr( name, 1, pos-1) AS first_name,
substr( name, pos+1) AS last_name
FROM (
SELECT
author.name,
numbers.x AS pos
FROM author
INNER JOIN numbers
WHERE substr( author.name, numbers.x, 1) = ' '
GROUP BY author.name
) AS a
ORDER BY last_name;
I have two tables(oracle):
(I have marked the primary keys with a star before the column name)
Table1 Columns are :
*date,
*code,
*symbol,
price,
weight
Table2 columns are :
*descriptionID
code
symbol
date
description
I need to find the below information using query,
For a given code and a symbol on a particular day,is there any description.
for example: code = "AA" and symbol = "TEST" on 2012-4-1 on Table 1 => is there atleast one row like ID=, code ="AA", symbol ="TEST" ,date = 2012-4-1 in table 2
I tried with the below query:
select * from Table1 t1 INNER JOIN
Table2 t2
on t1.code = t2.code and t1.symbol = t2.symbol and
TO_CHAR(t1.date, 'YYYY/MM/DD') = TO_CHAR(t1.date, 'YYYY/MM/DD')
But it doesnt give me output like:
code = AA, symbol = TEST, date 2012-4-1 => descrition count = 10
code = AA, symbol = TEST, date 2012-4-2 => descrition count = 5
code = BB, symbol = HELO, date 2012-4-1 => descrition count = 20
Can some one suggest me a query which can achieve the above output.
I don't see why you need the join:
SELECT count(*)
FROM Table2
WHERE code='AA'
AND symbol = 'TEST'
AND date = to_date('2012-04-01', 'yyyy-mm-dd')
UPDATE: (after reading your comment)
I still don't see why you need the join. Do you need some data from table1 ?
Anyway, if you want the count for all the (code,symbol,date)s then why not group by ?
As for the dates, better use trunc to get rid of the time parts.
So:
SELECT code, symbol, date, count(*)
FROM Table2
GROUP BY code, symbol, date
the Trunc() Method takes a String\Date input and Creates a DATE output that is in this Format: "DD\MM\YYYY".
So Its should do exactly what you want.
My original question
When I execute the following query in SQLite, I get this error:
Query Error: misuse of aggregate: sum() Unable to execute statement
When I change the name of the "Loan" column to something like loan_amount the error goes away and my query works fine. Why is there a problem with "Loan"?
select
t.*
, coalesce(sum(ded0.after_tax_ded_amt), 0) as "Loan"
, coalesce(sum(ded1.after_tax_ded_amt), 0) as ee_advance_amount
from totals t
left join totals as ded0
on t.ee_ssn = ded0.ee_ssn
and t.deduction_code = "Loan"
and ded0.deduction_code = "Loan"
left join totals as ded1
on t.ee_ssn = ded1.ee_ssn
and t.deduction_code = "EE Advance"
and ded1.deduction_code = "EE Advance"
group by t.ee_ssn;
Mid-post revelation
I'm pretty sure I figured out why I get the error, is it because I am comparing to "Loan" in the on-clause of my joins?
If so, how can I still use the word "Loan" for my column name in the output of my query?
I'd guess that your real problem is quote misuse. Single quotes in SQL are for quoting string literals, double quotes are for quoting column and table names that need to be case sensitive or contain odd characters. SQLite is fairly forgiving of odd syntax so it is probably making a guess about what "Loan" means and guessing incorrectly. Try this:
select
t.*
, coalesce(sum(ded0.after_tax_ded_amt), 0) as "Loan"
, coalesce(sum(ded1.after_tax_ded_amt), 0) as ee_advance_amount
from totals t
left join totals as ded0
on t.ee_ssn = ded0.ee_ssn
and t.deduction_code = 'Loan'
and ded0.deduction_code = 'Loan'
left join totals as ded1
on t.ee_ssn = ded1.ee_ssn
and t.deduction_code = 'EE Advance'
and ded1.deduction_code = 'EE Advance'
group by t.ee_ssn;
