I want to get data from database but the format of values that are compared do not tally.
The numbers in database are saved in weird format - sometimes are rounded and some of those are decimals (10, 14, 15, 12.44, 16.10, etc.)
In array I have values rounded on 2 decimals though.
I want to get data from database like so:
$foundPayments = $this>paymentsRepo>newQuery()>whereRaw("CONVERT(DECIMAL(10,2),payments.amount) = :payments", ['payments' => $payments]);
Althought, I end up with an error like this: Syntax error: 7 ERROR: syntax error at or near ","
I am not sure if the code works in laravel 5.1 with sending params like I do but thats not really what I do care for in that - the same error apperars even when I do not use variable.
EDIT:
I am using Postgres.
I think that the syntax that you are using for the convert function is wrong. You should first pass the value then the type to which you are converting to.
But please try the cast function, I think that it should give you the expected result.
$foundPayments = $this->paymentsRepo->newQuery()
->whereRaw("CAST(payments.amount as DECIMAL(10,2)) = :payments",
['payments' => $payments]);

I was trying to query the duration of a WWE wrestler in the matches which he won and here I have successfully retrieved the data:
I would like to remove those zeros and I tried the following piece of code:
strftime(%H:%M:%S, R1.time_in_match)
which doesn't work and give the following error:
': near "%": syntax error
The data I imported were from a data frame which stores the time as time object and put them into the database as type DATETIME. The typeof function used on the "time_in_match" field returned type TEXT.
I was wondering if there is any way to format the time.
Thanks!
SQLite provides 2 functions for this case:
strftime('%H:%M:%S', R1.time_in_match)
and simpler:
time(R1.time_in_match)
because:
The time() function returns the time as HH:MM:SS
(from Date And Time Functions)
See the demo.
Your expression works as intended if you surround the format specifier with single quotes:
strftime('%H:%M:%S', time_in_match)
You could also just use string functions here:
substr(time_in_match, 1, 8)

i have this String '5666,232343' and i want to convert it to Decimal, i use cast('5666,232343' as decimal(7,5)) but it returns NULL value.
Do you know why it doesn't work with CAST
Zorkolot is right. The current precision and scale that you've used is not sufficient for the value you've provided.
If you're using SQL Server 2012 or higher and you want to keep the comma in the value, then you can use the TRY_PARSE function and set a culture. It will return NULL if it encounters an error instead of not completing the statement and returning red text. This also allows you to add basic error handling to the statement, if you wanted, by getting failed conversions to return the value of zero. For example:
This is your original query (which is currently erroring) with my error handling fix:
select coalesce(try_parse('5666,232343' as decimal(7,5) using 'en-GB'),'0') as [DecimalValue]
This is the same thing as above but I've amended the decimal precision and scale so that the value is successfully converted:
select coalesce(try_parse('5666,232343' as decimal(16,6) using 'en-GB'),'0') as [DecimalValue]
This should prevent you having to perform a REPLACE either manually or by using the SQL function.
You need to cast to a decimal that can hold the value of 5666.232343.
DECIMAL(7,5) allows numbers in this format: ##.#####. The biggest number you can have then is 99.99999. You also need to take the comma out and replace it with a period:
SELECT CAST('5666.232343' as decimal(16,6)) AS [DecimalValue]
The problem is probably the comma. In some databases, some of the functions are not as internationally-sensitive as (I think) they should be. So try:
cast(replace('5666,232343', ',', '.') as decimal(7, 5))
I'm trying to run the following query on a database to replace the leading characters of certain rows.
UPDATE table SET path = :newpath || SUBSTRING(path FROM :pathlen)
WHERE path STARTING WITH :oldpath
So for parameter :newpath = foo, :oldpath = bar and :pathlen = 4, I want this
bar\wibble
to be changed to ...
foo\wibble
However, I get the error "expression evaluation not supported" and I'm not sure why. Replacing :pathlen with a literal 4 works correctly, so it's definitely the SUBSTRING causing the problem.
Is it possible to specify scale in a ABS function from a decimal ?
= ABS(([Accounting].salary+ABS([Accounting].expenses))/2)
As of right now everything works correctly but there is a problem with results when the number has only 1 number after the decimal point:
100.12 - All ok
230.1 - Not ok, it should be 230.10
I want the outcome to always have two numbers after the decimal point.
The query has to work on both MS SQL Server and Oracle. I can specify the query for each db manually.
To me, this is more a user interface issue than a SQL issue.
230.1 - Not ok, it should be 230.10
Seriously, that's both the same number.
In Oracle you can convert a number into a string in order to present it to an end user.
select to_char(234.1,'$9,999.99') from dual
$234.10
Have a look at format models in the Oracle documentation.
http://docs.oracle.com/cd/B19306_01/server.102/b14200/sql_elements004.htm
Just change code:
= ABS(([Accounting].salary+ABS([Accounting].expenses))/2)
By the following:
= CAST(ABS(([Accounting].salary+ABS([Accounting].expenses))/2) AS DECIMAL(18 /*set your format here instead of 18*/,2))
I've just checked it in code:
SELECT CAST(230.1 AS DECIMAL(18 /*set your format here instead of 18*/, 2))
And all works fine
In fact, it's just a question of representation of your numbers in the UI for the user. You can convert your number to the string with using to_char () with the format specified. But it is better to define the output format on the front-end
I am trying to duplicate a detail object from Desktop to its Webi equivalent.
I am familiar with the syntax differences, i.e. using semicolons instead of commas and using [] rather than <> to enclose references to other dimensions/measures/detail objects.
Given the working formula from the Deski report:
=ToDate(7+"/1/"+<Current FY>-1 ,"mm/dd/yyyy")
I tried to convert this using the syntax I know from Webi:
=ToDate(7+"/1/"+[Current FY]-1 ; "mm/dd/yyyy")
I faced the error message
The expression or sub-expression at position 8 in the '-' function uses an invalid data type
I am guessing this has something to do with trying to convert a date datatype into an integer in order to subtract "1." However, I do not know what kind of function this requires.
Thanks in advance!
