I am trying to run this query but the query keeps giving up on me:
Update StockInvoiceInfo set Quantity = Quantity - 2 where p_id = 5 AND ProductDate = convert(Cast('31-5-2015' as datetime)) ;
After Running this code it returns an error below:
Incorrect syntax near '31-5-2015'
The datatype of the ProductDate column isDate. I am using Sql Server 2012.
You have used Convert functions but didn't supplied it with parameters. Also there is no need for this function here. Also take care of date format. I have changed it to standard format:
Update StockInvoiceInfo set Quantity = Quantity - 2
where p_id = 5 AND ProductDate = Cast('2015-05-31' as datetime)
If all you are trying to do is compare a Sql Date, then just use an agnostic format like '20150531' or easier to read '2015-05-31'. No need for casts or convert at all, i.e.
WHERE ... AND ProductDate = '2015-05-31'
However, if ProductDate isn't a date, but one of the *DATETIME* data types, and you are looking to update any time on the same day, then I believe you are looking for something like:
Update StockInvoiceInfo
set Quantity = Quantity - 2
where
p_id = 5
AND CAST(ProductDate AS DATE) = '2015-05-31';
However, the performance will be lousy as the clause isn't likely to be SARGable. You're better off simply doing:
AND ProductDate >= '2015-05-31' AND ProductDate < '2015-06-01';
(Resist the temptation to use between, or hacks like ':23:59:59' as there will be data corner cases which will bite you)
use CAST('5-31-2015' as DATETIME)
with the above update statement you started convert but with incomplete syntax
here the convert syntax
Update StockInvoiceInfo
set Quantity = Quantity - 2
where p_id = 5
AND ProductDate = convert(datetime,Cast('31-5-2015' as varchar),103) ;

I am trying to implement Slowly Changing Dimension Type 2 through T-SQL but I can't figure out how to put a request to work.
Table columns: cpf, nome, telefone_update, endereco_insert
Basically the logic is: if the MATCH doesn't happen using cpf, then the record must be inserted; if the MATCH happens but only the telefone_update field has changed, there is no need to another record and I just want to UPDATE and override the values; if the MATCH happens but only the endereco_insert field has changed I want to add a new record and update the start and end dates.
What I have so far is:
insert into #dm_lucas_tst (
[cpf],
[nome],
[telefone_update],
[endereco_insert],
[dt_scd_start],
[dt_scd_end],
[nu_scd_version]
)
select [cpf],
[nome],
[telefone_update],
[endereco_insert],
cast(dateadd(month, datediff(month, 0, getdate()), 0) as date) as [dt_scd_start],
'2199-12-31' AS [dt_scd_end],
1 AS [nu_scd_version]
from (
merge edw.dim.dm_lucas_tst as Target
using edw.dim.stg_lucas_tst as Source
on Target.cpf = Source.cpf
when not matched by target
then
insert (
[cpf],
[nome],
[telefone_update],
[endereco_insert],
[dt_scd_start],
[dt_scd_end],
[nu_scd_version]
)
values (
Source.[cpf],
Source.[nome],
Source.[telefone_update],
Source.[endereco_insert],
cast(dateadd(month, datediff(month, 0, getdate()), 0) as date),
'2199-12-31',
1
)
when matched
and Source.telefone_update <> Target.telefone_update
and Target.dt_scd_end = '2199-12-31'
then
update set telefone_update = Source.telefone_update
output $ACTION ActionOut,
Source.[cpf],
Source.[nome],
Source.[telefone_update],
Source.[endereco_insert]
) AS MergeOut
where MergeOut.ActionOut = 'UPDATE';
But I don't think putting another WHEN MATCH AND ... will make that work.
Any suggestions?
Thanks in advance!
Accordingly to your description, I'm assuming that you need:
SCD Type 1 for column [telefone_update]
SCD Type 2 for column [endereco_insert]
I've used application SCD Merge Wizard to easily create described logic.
When I made tests for it - everything looks as expected, I guess.
I described the process on my blog - please have a look and tell me if that was exactly what you wanted?

In my problem which I am trying to solve, there is a performance values table:
Staff PerformanceID Date Percentage
--------------------------------------------------
StaffName1 1 2/15/2016 95
StaffName1 2 2/15/2016 95
StaffName1 1 2/22/2016 100
...
StaffName2 1 2/15/2016 100
StaffName2 2 2/15/2016 100
StaffName2 1 2/22/2016 100
And the SQL statement as follows:
SELECT TOP (10)
tbl_Staff.StaffName,
ROUND(AVG(tbl_StaffPerformancesValues.Percentage), 0) AS AverageRating
FROM
tbl_Staff
INNER JOIN
tbl_AcademicTermsStaff ON tbl_Staff.StaffID = tbl_AcademicTermsStaff.StaffID
INNER JOIN
tbl_StaffPerformancesValues ON tbl_AcademicTermsStaff.StaffID = tbl_StaffPerformancesValues.StaffID
WHERE
(tbl_StaffPerformancesValues.Date >= #DateFrom)
AND (tbl_AcademicTermsStaff.SchoolCode = #SchoolCode)
AND (tbl_AcademicTermsStaff.AcademicTermID = #AcademicTermID)
GROUP BY
tbl_Staff.StaffName
ORDER BY
AverageRating DESC, tbl_Staff.StaffName
What I am trying to do is, from a given date, for instance 02-22-2016,
I want to calculate average performance for each staff member.
The code above gives me average without considering the date filter.
Thank you.
Apart from your join conditions and table names which looks quite complex, One simple question, If you want the results for a particular date then why is the need of having
WHERE tbl_StaffPerformancesValues.Date >= #DateFrom
As you said your query is displaying average results but not for a date instance. Change the above line to WHERE tbl_StaffPerformancesValues.Date = #DateFrom.
Correct me if I am wrong.
Thanks for the replies, the code above, as you all say and as it is also expected is correct.
I intended to have a date filter to see the results from the given date until now.
The code
WHERE tbl_StaffPerformancesValues.Date >= #DateFrom
is correct.
The mistake i found from my coding is, in another block i had the following:
Protected Sub TextBoxDateFrom_Text(sender As Object, e As System.EventArgs) Handles TextBoxDate.PreRender, TextBoxDate.TextChanged
Try
Dim strDate As String = Date.Parse(DatesOfWeekISO8601(2016, WeekOfYearISO8601(Date.Today))).AddDays(-7).ToString("dd/MM/yyyy")
If Not IsPostBack Then
TextBoxDate.Text = strDate
End If
SqlDataSourcePerformances.SelectParameters("DateFrom").DefaultValue = Date.Parse(TextBoxDate.Text, CultureInfo.CreateSpecificCulture("id-ID")).AddDays(-7)
GridViewPerformances.DataBind()
Catch ex As Exception
End Try
End Sub
I, unintentionally, applied .AddDays(-7) twice.
I just noticed it and removed the second .AddDays(-7) from my code.
SqlDataSourcePerformances.SelectParameters("DateFrom").DefaultValue = Date.Parse(TextBoxDate.Text, CultureInfo.CreateSpecificCulture("id-ID"))
Because of that mistake, the SQL code was getting the performance values 14 days before until now. So the average was wrong.
Thanks again.
I have a dynamic result from Dapper query that contains records like this:
{DapperRow, billing_currency_code = 'USD', count(*) = '6'}
I'm able to access 'USD' by using rowVariable.billing_currency_code
To get '6' value I tried rowVariable["count(*)"] and rowVariable.kv["count(*)"] and unfortunately nothing works...
I can't change the count(*) column name in my case
How to get the '6' value from the rowVariable of type DapperRow in such case?
If the column name genuinely is "count(*)", then you can cast the row to a dictionary:
var data = (IDictionary<string,object>)row;
object value = data["count(*)"];
For that to work (at least, in SQL Server), your query would need to be something like:
select count(*) as [count(*)]
However, in most cases the column doesn't have a name, in which case: fix your query ;p
Actually, I'd probably say fix your query anyway; the following would be much easier to work with:
select count(*) as [Count]
Suppose Your Data as below
var Details={DapperRow, billing_currency_code = 'USD', count(*) = '6'}
as The columns is coming dynamically
var firstRow= Details.FirstOrDefault();
To get the heading columns of the data
var Heading= ((IDictionary<string, object>)firstRow).Keys.ToArray();
To get the value of the data by using key
var details = ((IDictionary<string, object>)firstRow);
var vallues= details[Heading[0]];
Hello from an absolute beginner in SQL!
I have a field I want to populate based on another table. For this I have written this query, which fails with: Msg 512, Level 16, State 1, Line 1
Subquery returned more than 1 value. This is not permitted when the subquery follows =, !=, <, <= , >, >= or when the subquery is used as an expression.
The statement has been terminated.
oK, here goes:
Update kre.CustomerOrderLineCopy
SET DepNo = (SELECT customerordercopy.DepNo
FROM kre.CustomerOrderCopy , kre.CustomerOrderLineCopy
WHERE CustomerOrderLineCopy.OrderCopyNo =kre.CustomerOrderCopy.OrderCopyNo)
WHERE CustomerOrderLineCopy.OrderCopyNo = (SELECT CustomerOrderCopy.OrderCopyNo
FROM kre.CustomerOrderCopy, kre.CustomerOrderLineCopy
WHERE kre.CustomerOrderLineCopy.OrderCopyNo = kre.CustomerOrderCopy.OrderCopyNo)
What I'm trying to do is to change DepNo in CustomerOrderLineCopy, with the value in DepNo in CustomerOrderCopy - based on the same OrderCopyNo in both tables.
I'm open for all suggestion.
Thanks,
ohalvors
If you just join the tables together the update is easier:
UPDATE A SET A.DepNo = B.DepNo
FROM kre.CustomerOrderLineCopy A
INNER JOIN kre.CustomerOrderCopy B ON A.OrderCopyNo = B.OrderCopyNo
The problem is that at least one of your sub queries return more than one value. Think about this:
tablePerson(name, age)
Adam, 11
Eva, 11
Sven 22
update tablePerson
set name = (select name from tablePerson where age = 11)
where name = 'Sven'
Which is equivalent to: set Sven's name to Adam and Eva. Which is not possible.
If you want to use sub queries, either make sure your sub queries can only return one value or force one value by using:
select top 1 xxx from ...
This may be enough to quieten it down:
Update kre.CustomerOrderLineCopy
SET DepNo = (SELECT customerordercopy.DepNo
FROM kre.CustomerOrderCopy --, kre.CustomerOrderLineCopy
WHERE CustomerOrderLineCopy.OrderCopyNo =kre.CustomerOrderCopy.OrderCopyNo)
WHERE CustomerOrderLineCopy.OrderCopyNo = (SELECT CustomerOrderCopy.OrderCopyNo
FROM kre.CustomerOrderCopy --, kre.CustomerOrderLineCopy
WHERE kre.CustomerOrderLineCopy.OrderCopyNo = kre.CustomerOrderCopy.OrderCopyNo)
(Where I've commented out kre.CustomerOrderLineCopy in the subqueries) That is, you were hopefully trying to correlate these subqueries with the outer table - not introduce another instance of kre.CustomerOrderLineCopy.
If you still get an error, then you still have multiple rows in kre.CustomerOrderCopy which have the same OrderCopyNo. If that's so, you need to give us (and SQL Server) the rules that you want to apply for how to select which row you want to use.
The danger of switching to the FROM ... JOIN form shown in #Avitus's answer is that it will no longer report if there are multiple matching rows - it will just silently pick one of them - which one is never made clear.
Now I look at the query again, I'm not sure it even needs a WHERE clause now. I think this is the same:
Update kre.CustomerOrderLineCopy
SET DepNo = (
SELECT customerordercopy.DepNo
FROM kre.CustomerOrderCopy
WHERE CustomerOrderLineCopy.OrderCopyNo = kre.CustomerOrderCopy.OrderCopyNo)
I have a database in PostgreSQL and I'm developing an application in PHP using this database.
The problem is that when I execute the following query I get a nice result in phpPgAdmin but in my PHP application I get an error.
The query:
SELECT t.t_name, t.t_firstname
FROM teachers AS t
WHERE t.id_teacher IN (
SELECT id_teacher FROM teacher_course AS tcourse
JOIN course_timetable AS coursetime
ON tcourse.course = coursetime.course
AND to_char(to_timestamp('2010-4-12', 'YYYY-MM-DD'),'FMD') = (coursetime.day +1)
)
AND t.id_teacher NOT IN (
SELECT id_teacher FROM teachers_fill WHERE date = '2010-4-12'
)
ORDER BY t.t_name ASC
And this is the error in PHP
operator does not exist: text = integer (to_timestamp('', 'YYYY-MM-DD'),'FMD') =
(courset... ^ HINT: No operator matches the given name and argument type(s).
You might need to add explicit type casts.
The purpose to solve this error is to use the ORIGINAL query in php with :
$date = "2010"."-".$selected_month."-".$selected_day;
SELECT ...
AND to_char(to_timestamp('$date', 'YYYY-MM-DD'),'FMD') = (coursetime.day +1)
)
AND t.id_teacher NOT IN (
SELECT id_teacher FROM teachers_fill WHERE date = '$date'
)
The error message seems quite clear to me. You are mixing strings and numbers. More precisely, you are converting a string ('2010-4-12') to a timestamp, then to a string, then comparing to an int. This is a type mess, and postgresql is quite strict with typing (for good reasons). What are you trying to do here ?
to_char(to_timestamp('2010-4-12', 'YYYY-MM-DD'),'FMD') = (coursetime.day +1))
Further, you should use a TIMESTAMP, just a DATE.
If (I'm not sure) you are tring to compare the day of week from a date formated as 'YYYY-MM-DD' to a given value (as an integer), you should better use date_part. For example (not tested):
date_part('dow' , to_date('2010-4-12', 'YYYY-MM-DD') ) = coursetime.day + 1
