Write two statements to read in values for my_city followed by my_state. Do not provide a
prompt. Assign log_entry with current_time, my_city, and my_state. Values should be separated
by a space. Sample output for given program if my_city is Houston and my_state is Texas:
2014-07-26 02:12:18: Houston Texas
Note: Do not write a prompt for the input values.
current_time = '2014-07-26 02:12:18:'
my_city = ''
my_state = ''
log_entry =
''' Your solution goes here '''
print(log_entry)
I've tried several solutions and it is only printing out the date and time. Since the date and
time is given, I figured to concatenate the city and state strings then add them under log
entry however it still only prints out the date. I can't enter the actual city and state
because there is a back end test where Zybooks add a different city and state. Here is what I
have tried so far.
concatenated_string = my_city + ' ' + my_state
log_entry = current_time + concatenated_string
Actually figured it out.
my_city = input("")
my_state = input("")
log_entry = (current_time + ' ' + my_city + ' ' + my_state)

Hi everyone I'm trying convert this code so it works in postgres. I figured I will use to_char(dateinquar:: date, 'mm/dd/yyyy') instead of convert(varchar,dateinquar,101). But I'm not sure what can be used instead of FOR XML PATH? I don't need to generate any XML document. How would I get multiple dates in a single row separated by comma for the case below?
Case d.Closing WHEN 0 THEN NULL WHEN 1 THEN (
substring((SELECT convert(varchar,dateinquar,101) + ', ' FROM PDT_tblAReasons sub
WHERE sub.IDnumber = d.IDnumber and dateoutquar IS NULL
GROUP BY IDnumber,dateinquar FOR XML PATH('')),0,len((
SELECT convert(varchar,dateinquar,101) + ', ' FROM PDT_tblAReasons sub
WHERE sub.IDnumber = d.IDnumber and dateoutquar IS NULL
GROUP BY IDnumber,dateinquar FOR XML PATH('')))-0)) end As [Closing Date]
Thank you

Long story short, I need a stored procedure that would get the data from a few different views and put it into a .CSV file. Easy enough, but me being me, I decided to write something that could get the data from any table one could potentially desire. I decided to go with 2 procedures in the end:
Loop through a table with all the parameters (catalog, schema, table name, export path/file name etc. etc.) and feed it to 2nd stored procedure (in theory it should make it easier to manage in future, if/when different data needs to be exported). This one is fairly straightforward and doesn't cause any issues.
Pick up the column names (which was surprisingly easy - below in case it helps anyone)
select #SQL = 'insert into Temp_Export_Headers ' +
'select COLUMN_NAME ' +
'from [' + #loc_Source_Database + '].information_schema.columns ' +
'where table_name = ''' + #loc_Source_Table + ''''
and
select #Headers = coalesce(#Headers + ',', '') + convert(varchar, Column_Name)
from Temp_Export_Headers
After that, I want to dump all the data from "actual" table into temp one, which in itself is easy enough, but that's where things start to go downhill for me.
select #SQL =
'drop table if exists TempData ' +
'select * ' +
'into TempData ' +
'from [' + #loc_Source_Database + '].' + #loc_Source_Schema + '.' + #loc_Source_Table + ' with (nolock) '
Select * is just temporary, will probably replace it with a variable later on, for now it can live in this state on dev.
Now I want to loop through TempData and insert things I want (everything at the moment, will add some finesse and where clauses in near future) and put it into yet another temp table that holds all the stuff for actual CSV export.
Is there any way to add a self incrementing column to my TempData without having to look for and get rid of the original PK / Identity? (Different tables will have different values / names for those, making it a bit of a nightmare for someone with my knowledge / experience to loop through in a sensible manner, so I'd just like a simple column starting with 1 and ending with whatever last row number is)
#ShubhamPandey 's answer was exactly what I was after, code below is a product of my tired mind on the verge of madness (It does, however, work)
select #SQL =
'alter table TempData ' +
'add Uni_Count int'
select #SQL2 =
'declare #UniCount int ' +
'select #UniCount = 0 ' +
'update tempdata with (rowlock) ' +
'set #UniCount = Uni_Count = #UniCount + 1'
Both versions execute quicker than select * into without any other manipulation. Something I cannot yet comprehend.
Is there a better / more sensible way of doing this? (My reasoning with the loop - there will potentially be a lot of data for some of the tables / views, with most of them executed daily, plan was to export everything on Sat/Sun when system isn't that busy, and have daily "updates" going from last highest unique id to current.)
Looping was a horrible idea. To illustrate just how bad it was:
Looping through 10k rows meant execution time of 1m 21s.
Not looping through 500k rows resulted in execution time of 56s.
Since you are doing a table creation while insertion, you can always go forward with a statement like:
select #SQL =
'drop table if exists TempData ' +
'select ROW_NUMBER() OVER (<some column name>) AS [Id], * ' +
'into TempData ' +
'from [' + #loc_Source_Database + '].' + #loc_Source_Schema + '.' + #loc_Source_Table + ' with (nolock) '
This would create an auto-incrementing index for you in the TempData table
I am trying to create a script that builds a SQL statement dynamically and then executes it.
Here is the string that is built & stored in #strSQL (verified by using PRINT)
UPDATE DNN_RSM_Exams
SET ScoringDates = REPLACE(ScoringDates, '/2015', '/2016')
WHERE SchoolYear = 2015
It executes the variable as follows:
EXECUTE (#strSQL)
However I get the following error:
Conversion failed when converting the nvarchar value 'UPDATE DNN_RSM_Exams SET ScoringDates = REPLACE(ScoringDates, '/' to data type int.
It seems to terminate the EXECUTE when it hits the first forward-slash (/). I tried escaping it using a double slash (//), an open bracket ([), and a backslash (\). None if it worked.
Can anyone help me please?
UPDATE #01: 8/17/15
Sorry if I didn't give enough information initially...
ScoringDates is an NVARCHAR(MAX) field.
The Code that builds the SQL Statement is:
SET #strSQL = 'UPDATE ' + #strTableName +
' SET ScoringDates = REPLACE(ScoringDates, ''/' + LTRIM(RTRIM(STR(#intSchoolYear_CopyFrom + 1))) + ''', ''/' + LTRIM(RTRIM(STR(#intSchoolYear_CopyFrom + 2))) + ''')' +
' WHERE SchoolYear = ' + LTRIM(RTRIM(STR(#intSchoolYear_CopyTo)))
ScoringDates is a string based field that holds data in an INI-like formatted string. I want to change the year portion of ANY date found in the string, but I want to avoid accidental changes of any other numbers that may match. So I am specifically looking to replace "/YYYY" with a different "YYYY" value. The "/" preceding the year value is to ensure that what is being preplaced is the YEAR and not another numeric value within the string.
UPDATE #02: 8/18/15
So I am completely flabbergasted...after banging my head on this script for hours yesterday, I went home defeated. Come in today, start up my PC and run the script again so I can see the error message again...and it worked!
I've never come across this with SQL Management Studio, but it is possible that SQL Management Studio somehow lost it's marbles yesterday and needed a reboot? I thought the SQL was process by the server directly. Could it be that some is processed by the studio first before handing it off to the server and if the studio had "issues" then it would cause strange errors?
In any case, thank you so much guys for your input, I am sorry that it was a wheel spinner. It never occurred to me that a reboot would fix my issue, I just assumed my code was wrong.
You want to replace '/ with ''
So your set statement will be something like...
SET #strSQL = 'UPDATE DNN_RSM_Exams
SET ScoringDates = REPLACE(ScoringDates, ''2015'', ''2016'')
WHERE SchoolYear = 2015'
EDIT:
How is your code different than this below? (I will edit this again and clean it up after. Code just won't fit into comments)
DECLARE #TableName TABLE (ScoringDates VARCHAR(100), SchoolYear INT)
DECLARE #strTableName VARCHAR(MAX)
DECLARE #intSchoolYear_CopyFrom VARCHAR(MAX)
DECLARE #intSchoolYear_CopyTo VARCHAR(MAX)
SET #strTableName = '#TableName'
SET #intSchoolYear_CopyFrom = '2009'
SET #intSchoolYear_CopyTo = '2010'
DECLARE #strSQL VARCHAR(MAX)
SET #strSQL = 'DECLARE #TableName TABLE (ScoringDates VARCHAR(100), SchoolYear INT); UPDATE ' + #strTableName +
' SET ScoringDates = REPLACE(ScoringDates, ''/' + LTRIM(RTRIM(STR(#intSchoolYear_CopyFrom + 1))) + ''', ''/' + LTRIM(RTRIM(STR(#intSchoolYear_CopyFrom + 2))) + ''')' +
' WHERE SchoolYear = ' + LTRIM(RTRIM(STR(#intSchoolYear_CopyTo)))
PRINT #strSQL
EXECUTE (#strSQL)
I am trying to normalize my tables to make the db more efficient.
To do this I have removed several columns from a table that I was updating several columns on.
Here is the original query when all the columns were in the table:
UPDATE myActDataBaselDataTable
set [Correct Arrears 2]=(case when [Maturity Date]='' then 0 else datediff(d,convert(datetime,#DataDate, 102),convert(datetime,[Maturity Date],102)) end)
from myActDataBaselDataTable
Now I have removed [Maturity Date] from the table myActDataBaselDataTable and it's necessary to retrieve that column from the base reference table ACTData, where it is called Mat.
In my table myActDataBaselDataTable the Account number field is a concatenation of 3 fields in ACTData, thus
myActDataBaselDataTable.[Account No]=ac.[Unit] + ' ' + ac.[ACNo] + ' ' + ac.[Suffix]
(where ac is the alias for ACTData)
So, having looked at the answers given elsewhere on SO (such as 1604091: update-a-table-using-join-in-sql-server), I tried to modify this particular update statement as below, but I cannot get it right:
UPDATE myActDataBaselDataTable
set dt.[Correct Arrears 2]=(
case when ac.[Mat]=''
then 0
else datediff(d,convert(datetime,'2014-04-30', 102),convert(datetime,ac.[Mat],102))
end)
from ACTData ac
inner join myActDataBaselDataTable dt
ON dt.[Account No]=ac.[Unit] + ' ' + ac.[ACNo] + ' ' + ac.[Suffix]
I either get an Incorrect syntax near 'From' error, or The multi-part identifier "dt.Correct Arrears 2" could not be bound.
I'd be grateful for any guidance on how to get this right, or suugestiopns about how to do it better.
thanks
EDIT:
BTW, when I run the below as a SELECT it returns data with no errors:
select case when [ac].[Mat]=''
then 0
else datediff(d,convert(datetime,'2014-04-30', 102),convert(datetime,[ac].[Mat],102))
end
from ACTData ac
inner join myActDataBaselDataTable dt
ON dt.[Account No]=ac.[Unit] + ' ' + ac.[ACNo] + ' ' + ac.[Suffix]
In a join update, update the alias
update dt
What is confusing is that in later versions of SQL you don't need to use the alias in the update line
I have a function that takes in the personalia of a person
function person = prompt_person ()
name = input ( ' Whats your name ? ' , 's' ) ;
day = input ( ' What day of the month were you born ? ') ;
month = input (' What month were you born ? ') ;
year = input ( ' What year were you born? ') ;
phone = input ( ' Whats your telephone number ? ') ;
date_of_birth = struct ('day', day, 'month', month, 'year', year) ;
person = struct ( 'name' , name, 'date_of_birth' , date_of_birth , 'phone' , phone ) ;
end
But I keep getting the error message "Invalid field name "name" ", "Error message in prompt_person (line 8) And I have no idea whats wrong because I've tried creating a simpler little test function:
function [out] = tes( )
word=input('Insert word here ','s');
num=input('Insert number here ');
out= struct('Number1', word, 'Number2', num);
end
And it works just fine, even though it seems to be the exact same code which gets me in toruble in the first function. Any ideas what's going on here?
I tried changing the variable name to personName as suggested and I accidentaly found out whats wrong:
Turn out I needed to use a variable name with no space between the '' and the text.
E.g. 'PersonName' instead of ' PersonName '.
You might consider using strtrim to strip leading and trailing whitespeace from a string. For example:
>> name = ' John Doe ';
>> name = strtrim(name)
name =
John Doe
If you need to remove all spaces, try strrep(name,' ','').
>> name = strrep(name,' ','')
name =
JohnDoe
