SQL Server 2012 :: Merging Two Tables Based On Date Field?
Sep 8, 2015
I have two tables like,
create table dbo.#Status(
ID varchar(50),
Status varchar(50),
EffectiveStartDate datetime,
EffectiveEndDate datetime,
Is_Current bit
[code].....
I want result as the attached image.
Create table query for result is: CREATE TABLE dbo.#Result(
ID varchar(50),
Fee varchar(100),
Bill varchar(50),
A_Date date,
B_Date date,
Status VARCHAR(50),
EffectiveStartDate datetime,
EffectiveEndDate datetime
)
I have two tables. Status and Fourhistory tables.Status table contains a status column with effectivestart and end dates as history. This column is having history at month level.
Fourhistory table maintains 4 columns as part of history with the use of effectivestart and end dates. Here history capturing is at day level.
Desired Result: I want to merge the status column into FourHistory table.Below i have given some possible sample scenarios which i face and the third table contains the expected ouput.how to achieve this in T-SQL query.
create table dbo.#Status( ID varchar(50), Status varchar(50), EffectiveStartDate datetime, EffectiveEndDate datetime, Is_Current bit
I have a source table in the staging database stg.fact and it needs to be merged into the warehouse table whs.Fact.
stg.fact is not a delta feed it is basically an intra-day refresh.
Both tables have a last updated date so its easy to see which have changed.
It will be new (insert) or changed (update) data that I am interested in, there are no deletions.
As this could be in the millions of rows that are inserts or updates then this needs to be efficient.
I expect whs.Fact to go to >150 million rows.
When I have done this before I started with T-SQL Merge statement and that was not performant once I got to this size.
My original option was to do this is SSIS with a lookup task that marks the inserts and updates and deal with them seperately. However I set up the lookup tranformation the reference data set will have a package variable in the SQL commnd. This does not seem possible with the lookup in 2012! Currently looking at Merge Join transformation and any clever basic T-SQL that could work as this will need to be fast, and thats where I think that T-SQL may be the better route.
Both tables will have >100,000,000 rows Both tables have the last updated date The Tables are in different databases but on the same SQL Instance Each table holds 5 integer columns, one Varchar, one datatime
Last time I used Merge it was a wider table with lots of columns so don't know if this would be an option.
I have a query to run a report where the results has a column named “Due Date” which holds a date value based on the project submission date.Now, I need to add 4 columns named, “45 Days Expectant”, “30 Days Overdue”, “60 Days Overdue” and “90 Days Overdue”.I need to do a calculation based on the “Due Date” and “System (I mean default computer date) Date” that if “System Date” is 45 days+ to “Due Date” than put “Yes” in “45 Days Expectant” row.
Also, if “Due Date” is less than or equal to system date by 30 days, put “Yes” in “30 Days Overdue” and same for the 60 and 90 days.how to write this Case Statement? I have some answers how to do it in SSRS (Report Designer) but I want to get the results using T-SQl.
I am trying to update records based on the results of a query with a subquery.
The result set being produced shows the record of an item number. This result produces the correct ItemNo which I need to update. The field I am looking to update is an integer named Block.
When I run the update statement all records are updated and not the result set when I run the query by itself.
Below is the code I am using in an attempt to update the block column but it updates all records and not the ones which I need to have the Blocked field set to 1.
Update #items set Blocked = 1 Where Exists ( SELECT ItemNo=MAX(CASE rn WHEN 1 THEN ItemNo END) --,SearchNo --,COUNT(*)
[Code] ...
Why is the update changing each record? How can I change the update to choose the correct records?
I'm writing a view to check record counts in a table that has numerous datasets and therefore various "Activity Dates". Is it possible as part of the SQL statement to have a CASE statement for example so that it can identify the field to use as the activity date?
The field to use is being identified using a seperate table so at the moment I have CASE WHEN FieldToUse = '2' THEN MapCol ELSE '[Activity_Date]' END, where FieldToUse = '2' identifies the date field to use and the MapCol data is the field name to be used as the activity date.
We have a database and have 6-7 growing tables. All the tables have Primary and foreign key relation. I want to do partition based on the date column.
I need 3 partitions
First partition has to hold present data second partition need to hold the previous year data (SAS storage) Third partition need to hold all the old data and need to be in the archive database
I understand that first we need to disable the constraints (Indexes PK & FK) Then create partition function and partition schema Then Create the Constraints again
I have a client data which has the candidate id, a start date which will have only the date in varchar format and a time value associated to that date in varchar format in a seperate column.
To give a brief explanation about the data a candidate will come to study center at any time point in a day for example 10:00 AM on 20-10-2014. The start date will be 20-10-2014 and from 10:00 AM he will have test based on the time point. So if the time point is 2 HR, then at 12:00 PM he will have a test. If the time point is 8 HR, it will get added with 10:00 AM and based on this he will have the test at 06:00 PM. When the timepoint reaches 00:00 the start date needs to be the next date instead of 20-10-2014.
The start date needs to be appended with the time value such that when it crosses over the time 00:00, the start date needs to get increased by 1 ie the next day. I have added the start date to the time by using the code below
CAST(STARTDATE as datetime) + CAST(CAST(STUFF([TIME],3,0,':') as time(0)) as datetime) as [EXPECTEDDATETIME]
By this above code i have created the expected datetime however
I will not be able to hardcode the value due to dynamic data. I tried to apply >= and < to the time value something like
case when MyTime >= '00:00' and MyTime < '08:10' the Dateadd(day, 1, date)
This works perfect but my concern is that I cannot put the value 08:10 because it will not a constant value for all rows.
I have provided a screenshot of my data and a expected date column for reference.
Here is the desired counted output, I would like to pull distinct Date, MachineNumber, TestName and then count how many times they occur in the raw data form.I do need to perform a case on the date because right now its in a datetime format and I only need the date.
I am pulling three columns with the same names from 8 different tables. What I need to display the date, machine & test name and count how many times a test was run on a machine for that date. I have a feeling this can be handled by SSAS but haven't built an analysis cube yet because I am unfamiliar with how they work. I was wondering if this is possible in a simple query. I tried to set something up in a #Temp table. Problem is the query takes forever to run because I am dealing with 1.7 Million rows. Doing an insert into #temp select columnA, columnB, columnC from 8 different tables takes a bit.
I have a table of "applicants" with unique applicant id and another table "reviews" with reviews which has unique id and Emplid and contains general program name like Math and then may contain 3 addition rows for specific program like Calculus, algebra, geometry etc.
There may or may not be a record for each applicant id in table reviews or there can be 1 or more than one record in reviews based on level of review( General or Specific).
All the general reviews has “Math” as Program_code but if there are more reviews, they can have Program_code like “Cal” , “Abr”, “Geo”
I want to join the tables so I can get all the records from both the tables where Program_code in reviews table is “Math” only.
That is I want to join the table and get all the records from reviews table where the program_code is “Math” only How can I do that?
I have a date held in a varchar field in a temporary sql table and I want to convert it into a sql date and it doesn't work. I can replicate this as below -
I have two tables: TestA and TestB. Both tables have 3 fields: ID,Name, and RunDate. I need to create a query which will join the twotables first on Name but then I need to match up the RunDates eventhough the RunDates won't be the same.CREATE TABLE TestA (ID INT IDENTITY, Name VARCHAR(255), RunDateDATETIME)CREATE TABLE TestB (ID INT IDENTITY, Name VARCHAR(255), RunDateDATETIME)INSERT INTO TestA VALUES ('Account 1', '9/1/2004 12:00PM')INSERT INTO TestB VALUES ('Account 1', '9/1/2004 12:15PM')INSERT INTO TestA VALUES ('Account 1', '9/2/2004 1:00PM')INSERT INTO TestB VALUES ('Account 1', '9/2/2004 1:15PM')INSERT INTO TestA VALUES ('Account 1', '9/3/2004 3:00PM')INSERT INTO TestA VALUES ('Account 2', '9/5/2004 4:00PM')INSERT INTO TestB VALUES ('Account 2', '9/5/2004 4:15PM')Here's a common scenario:User updates TestA data for Account 1 on 9/1/2004 at 12:00pm. Thenthe user updates TestB data for Account 1, 15 minutes later. I wantthese two records to match. The user must always update TestA databefore they update TestB data. Therefore, there might be more rows inTestA then in TestBHere's what the results should look like for the above data.Name TestA Date TestB Date---- ---------- ----------Account 1 9/1/2004 12:00pm 9/1/2004 12:15PMAccount 1 9/2/2004 1:00pm 9/2/2004 1:15PMAccount 1 9/3/2004 3:00pm (NULL)Account 2 9/5/2004 4:00pm 9/5/2004 4:15PMAny help would be much appreciated!!!!
I want to group by a fields value in a table. I have a purchase table where contracts and orders are stored in together. Now what I need is, I have to group only by the rows that contain an identical contract_no and order_no as those records represent the actual contract. the other rows contain order data-sets which need to be subtracted from the contracts values.
I have tables in my database, tblNames1, tblNames2, tblNames3, and a main addresses table (currently empty). Once I've imported the address data I need to match the addressIDs in the names tables to the Primary ID in the address table based on the values of a field CompanyName (which is common to all the tables) My issue is that I have a huge CSV file with the master address information but obviously SQL server needs to assign foreign keys so the names tables can linked to corresponding rows in address table. It's a a many to 1 relationship as their will be one address with multiple name entries. All the names are normalized so everything can be matched up...
I am trying to match records that are >= the current date. I have tried using: SELECT DISTINCT name FROM table WHERE datefield >= DATEPART(month, GETDATE()) AND datefield >= DATEPART(day, GETDATE()) AND datefield >= DATEPART(year, GETDATE()) ORDER BY name but this is not giving me the result that I am looking for. What is the best way to match a DateTime field type using the current date without the time?
I need to send an email when my 'LastRunDate' field is 30 days old (i.e. It should send an email if the LastRunField = 7/21/2007).
I would need to include the matching fields in the database (i.e. MachineID, Description, etc.) then update that field to todays date.
I have a few values in the 'Frequency' field such as Daily, Monthly, Yearly. Daily would be 24 hrs, monthly 30 days, yearly 365 days from the lastrundate.
I think I got all my create table statements are correct.
I need to Find the number of agents for each supplier that has at least one agent. The result should be tuples of the form (sid, sName, number of agents)
-Select Sid, sName, count(Aid) from Agent A join Supplier S on (S.Sid = A.Sid) group by S.Sid, S.sName, Aid; But it gives me this error: no such column: A.Sid
Im thinking I might have a problem with my create table statement and/or primary key statements?
I have a detailed report in ssrs in which data can come from start date and end date parameters.
but the problem is. for example i gave startdate as 01/01/2015 and end date as 09/31/2015 then the data must be in displayed in such a way that jan month in one tab and feb month data in one tab and sooo on to sep month data in new tab when i export to Excel.
I have two tables tbl1 and tbl2, which I do a full outer join between tbl1 and tbl2 on recordId field. The recordId field is not a key in either of the tables.
If there is one row each for a recordId 123 in both tables, the select query would return one combined row.
If tble1 had two rows for recordId 123, and tbl2 had one row for the same, it would return to rows repeating the data in tbl2.
If tbl2 had two rows and bl1 had one row, it would return two rows in output repeating the data in tbl1.
Is the above correct? Would the result be different if it was an inner join instead of full outer join?
Is it ever possible that one of the two records with recordId 123 will be dropped from the result?
I have to produce a report to calculate no of days based on user input start date and end date.
say for eg: in the tables I have emp name user 'Phani' started work from - EStart 20/11/2014EEnd 10/01/2015 - total days --datediff within his work period he did different roles:
PhaniMarketing (prSt Date) 20/11/2014prE date (28/11/2014) Total 9 days PhaniAdmin (prSt Date) 29/11/2014prE date (20/12/2014) Total 22 days PhaniCRM (prSt Date) 20/12/2014prE date (10/01/2015) Total 22 days Total days 53 Days for this :
[code]...
HOW CAN I USE Case statement to calculate days for given start date and end date. I have to include all three totals, 1 for Job dates, 2, subjobs dates, 3 cal of days for a requested period.
I have soma ado.net code that inserts 7 parameters in a database ( a date, 6 integers). I also use a self incrementing ID but the date is set as primary key because for each series of 6 numbers of a certain date there may only be 1 entry. Moreover only 1 entry of 6 integers is possible for 2 days of the week, (tue and fr). I manage to insert a row of data in the database, where the date is set as smalldatetime and displays as follows: 1/05/2007 0:00:00 in the table. I want to retrieve the series of numbers for a certain date that has been entered (without taking in account the hours and seconds). A where clause seems to be needed but I don’t know the syntax or don’t find the right function I use the following code to insert the row :
and the following code to get the row back (to put in arraylist):
“SELECT C1, C2, C3, C4, C5, C6 FROM Series WHERE (LDate = Today())? WHERE LDate = '" + DateTime.Today.ToString() + "'"
Which is the correct syntax? Is there a better way to insert and select based on the date?
I don’t get any error messages and the code executes fine but I only get an empty datatable in my dataset (the table isn’t looped for rows I noticed while debugging). Today’s date is in the database but isn’t found by my tsql code I think.
I have a query that will generate records monthly based on the number of months that i calculate between two date feilds for a given requestid. How can i use the same query to generate records for weekly and bi weekly based on the receiveddate field that i use in the subtraction for calculating the number of months.
Also when inserting i have been adding a month for every record as i was generating monthly and now i would have to add week and 2 weeks to the receiveddate

Hello Experts, Been struggling with this issue all morning and beginning to get a headache. Essentialy my problem is this. I have a gridview control that ive bound to datasource where the select statement is using an inner join to retrieve textual info from one table in refernce to an object_id contained within both. i.e SelectCommand="SELECT 'multiple fields from both tables'FROM ZCRMTAB_ACTIVITY INNER JOIN ZCRMTAB_ACT_LOG ON ZCRMTAB_ACT_LOG.OBJECT_ID = ZCRMTAB_ACTIVITY.OBJECT_ID WHERE (ZCRMTAB_ACTIVITY.REF_CUST_NO = @REF_CUST_NO) ORDER BY ZCRMTAB_ACTIVITY.CREATED_AT DESC"> <SelectParameters><asp:QueryStringParameter Name="fieldName" QueryStringField="value" Type="String" /> My problem is that this returns individual row results and are displayed on individual lines. Where the object_id is the same i want all the textual info to be displayed within the same row. Does anyone know how i can accomplish this? Thanks in advance
I am trying to drag data from Informix to Sql Server. When I kick off the package using an OLE DB Source and a SQL Server Destination, I get DT_DBDATE to DT_DBTIMESTAMP errors on two fields from Informix which are date data ....no timestamp part
I tried a couple of things:
Created a view of the Informix table where I cast the date fields as datetime year to fraction(5), which failed.
Altered the view to convert the date fields to char(10) with the hopes that SQL Server would implicitly cast them as datetime but it failed.
We are using lookup transformation in SSIS 2012. The lookup transformation queries a table with two date columns. When we hover the mouse over the two columns in the 'columns' tab of the lookup transformation editor, the two columns show as DT_WSTR instead of DT_DBDATE. This causes the SSIS package to fail due to data type mismatch.A similar abandoned thread is available at: URL....
i have two columns in sql which is datetime datatype fromdate & todate, now i want to display it like fromdate-todate in my front end select fromdate +'-'+ todate as date from table. when i use this query , the error is The conversion of a char data type to a datetime data type resulted in an out-of-range datetime value. Thanks for any help
