Transact SQL :: Select And Parse Json Data From 2 Columns Into Multiple Columns In A Table?
Apr 29, 2015
I have a business need to create a report by query data from a MS SQL 2008 database and display the result to the users on a web page. The report initially has 6 columns of data and 2 out of 6 have JSON data so the users request to have those 2 JSON columns parse into 15 additional columns (first JSON column has 8 key/value pairs and the second JSON column has 7 key/value pairs). Here what I have done so far:
I found a table value function (fnSplitJson2) from this link [URL]. Using this function I can parse a column of JSON data into a table. So when I use the function above against the first column (with JSON data) in my query (with CROSS APPLY) I got the right data back the but I got 8 additional rows of each of the row in my table. The reason for this side effect is because the function returned a table of 8 row (8 key/value pairs) for each json string data that it parsed.
1. First question: How do I modify my current query (see below) so that for each row in my table i got back one row with 19 columns.
SELECT A.ITEM1,A.ITEM2,A.ITEM3,A.ITEM4, B.*
FROM PRODUCT A
CROSS APPLY fnSplitJson2(A.ITEM5,NULL) B
If updated my query (see below) and call the function twice within the CROSS APPLY clause I got this error: "The multi-part identifier "A.ITEM6" could be be bound.
2. My second question: How to i get around this error?
SELECT A.ITEM1,A.ITEM2,A.ITEM3,A.ITEM4, B.*, C.*
FROM PRODUCT A
CROSS APPLY fnSplitJson2(A.ITEM5,NULL) B, fnSplitJson2(A.ITEM6,NULL) C
I am using Microsoft SQL Server 2008 R2 version. Windows 7 desktop.
select CurrencyCode,TransactionCode,TransactionAmount,COUNT(TransactionCode) as [No. Of Trans] from TransactionDetails where CAST(CurrentTime as date)=CAST(GETDATE()as date) group by TransactionCode, CurrencyCode,TransactionAmount order by CurrencyCode
select CurrencyCode,TransactionCode,TransactionAmount,COUNT(TransactionCode) as [No. Of Trans] from TransactionDetails where CAST(CurrentTime as date)=CAST(GETDATE()as date) group by TransactionCode order by CurrencyCode
But of course this codes gives an error, but how can I get my desired result??
I'm working on a sales commission report that will show commissions for up to 5 sales reps for each invoice. The invoice detail table contains separate columns for the commission rates payable to each rep, but for some reason the sale srep IDs are combined into one column. The salesrep column may contain null, a single sales rep id, or up to five slaes rep IDs separated by the '~' character.
So I'd like to parse the rep IDs from a single column (salesreplist) in my invoice detail table (below) to multiple columns (RepID1, RepID2, RepID3, RepID4,RepID5) in a temp table so I can more easily calculate the commission amounts for each invoice and sales rep.
Here is my table:
CREATE TABLE invcdtl( invoicenum int, salesreplist [text] NULL, reprate1 int NULL, reprate2 int NULL, reprate3 int NULL, reprate4 int NULL, reprate5 int NULL, )
As you can see, some records have trailing delimiters but some don't. This may be a result of the application's behavior when multiple reps are entered then removed from an invoice. One thing for sure is that when there are multiple reps, the IDs are always separated by '~'
So I have been trying to get mySQL query to work for a large database that I have. I have (lets say) two tables Table_One and Table_Two. Table_One has three columns: Type, Animal and TestID and Table_Two has 2 columns Test_Name and Test_ID. Example with values is below:
In Table_One all types come under one column and the values of all Types (Mammal, Fish, Bird, Reptile) come under another column (Animals). Table_One and Two can be linked by Test_ID
I am trying to create a table such as shown below:
This should be my final table. The approach I am currently using is to make multiple instances of Table_One and using joins to form this final table. So the column Bird, Reptile, Mammal and Fish all come from a different copy of Table_one.
For e.g
Select Test_Name AS 'Test_Name', Table_Bird.Animal AS 'Birds', Table_Mammal.Animal AS 'Mammal', Table_Reptile.Animal AS 'Reptile, Table_Fish.Animal AS 'Fish' From Table_One
[Code] .....
The problem with this query is it only works when all entries for Birds, Mammals, Reptiles and Fish have some value. If one field is empty as for Test_Two or Test_Three, it doesn't return that record. I used Or instead of And in the WHERE clause but that didn't work as well.
I'd like to first figure out the count of how many rows are not the Current Edition have the following:
Second I'd like to be able to select the primary key of all the rows involved
Third I'd like to select all the primary keys of just the rows not in the current edition
Not really sure how to describe this without making a dataset
CREATE TABLE [Project].[TestTable1]( [TestTable1_pk] [int] IDENTITY(1,1) NOT NULL, [Source_ID] [int] NOT NULL, [Edition_fk] [int] NOT NULL, [Key1_fk] [int] NOT NULL, [Key2_fk] [int] NOT NULL,
[Code] .....
Group by fails me because I only want the groups where the Edition_fk don't match...
I have a Problem with my SQL Statement.I try to insert different Columns from different Tables into one new Table. Unfortunately my Statement doesn't do this.
If object_ID(N'Bezeichnungen') is not NULL Drop table Bezeichnungen; GO create table Bezeichnungen ( Artikelnummer nvarchar(18), Artikelbezeichnung nvarchar(80), Artikelgruppe nvarchar(13),
I am facing a problem in writing the stored procedure for multiple search criteria.
I am trying to write the query in the Procedure as follows
Select * from Car where Price=@Price1 or Price=@price2 or Price=@price=3 and where Manufacture=@Manufacture1 or Manufacture=@Manufacture2 or Manufacture=@Manufacture3 and where Model=@Model1 or Model=@Model2 or Model=@Model3 and where City=@City1 or City=@City2 or City=@City3
I am Not sure of the query but am trying to get the list of cars that are to be filtered based on the user input.
I'm trying to write a stored procedure that will parse XML attributes and populate columns within a DB with the stripped data. I'm a complete novice who prior to this week knew nothing about SQL commands, My understanding at least is that I need to perform a bulk insert.
Example XML file:
<?xml version="1.0" encoding="ISO-8859-1"?> <!DOCTYPE Asset_Collection SYSTEM "Asset_Collection.dtd"> <Asset_Collection> <Collection_Metadata Name="Asset Collection" Description="Random XML Feed Test"
[Code] ....
Table/Columns which need to be inserting into: Table: TABLE_A
We are using a table that may give 1 to and unknown number of data elements (ie. years) . How can we break this to show only three years in each row. Since we don't know the number years we really won't know the number of rows needed. Years are stored in their own table by line.
car make year1 year2 year3 A volare 1995 1996 1997 a volare 1997 1998 1999 b toyat 1965 1966 1968
We can pivot out the first X# but we don't know how many lines so we don't know how many rows we will be creating.
Sorry for the confusing subject. Here's what im doing:I have a table of products. Products have N categories andsubcategories. Right now its 4. But there could be more down theline so it needs to be extensible.So ive created a product table. Then a category table that has manycategories of products, of which a product can belong to N number ofthese categories. Finally a ProductCategory "match" table.This is pretty straigth forward. But im getting confused as to how towrite views/sprocs to pull out rows of products that list all theproducts categories as columns in a single query view.For example:lets say productId 1 is Cap'n Crunch cereal. It is in 3 categories:Cereal, Food for Kids, Crunchy food, and Boxed.So we have:Product----------------1 Capn CrunchCategories-----------------1 Cereal2 Food for Kids3 Crunchy food4 BoxedProductCategories------------------1 11 21 31 4How do I go about writing a query that returns a single result set fora view or data set (for use in a GridView control) where I would havethe following result:Product results---------------------------------ProductId ProductName Category 1 Category 2Category 3 Category N ...------------------------------------------------------------------------1 Capn Crunch Cereal Food for Kids Crunchy foodBoxedAm I just thinking about this all wrong? Sure seems like it.Cheers,Will
I have a data flow task in which there is a OLEDB source, derived column item, and a oledb destination. My source is a SQL command, that returns some values. I have some values, that I define in the derived columns, and set default values under the expression column. My question is, I also have some destination columns which in my OLEDB destination need another SQL command. How would I do that? Can I attach two or more OLEDB sources to one destination? How would I accomplish that? Thanks
I'm working on a data analysis involving a table with a large number of records (close to 2 million). I'm using only three of the columns in the table and basically am grouping results based on different criteria. The three columns are PWSID, Installation and AccountType. I have to Provide the PWSID column with a count of the total number of installations per PWSID, also a count of AccountTypes per PWSID. I have the following query, but the numbers aren't adding up and I'm not sure why. I'm falling short in the total count by around 60k records.
I am looking for a way to get the PRODUCT of all columns and group by M_DOMA, [FROM] - Basically multiply all columns on the row that are not M_DOMA or [FROM].
Select ID, FIRST(forename), FIRST(surname) from table1 GROUP BY ID;
I know First doesn't work in TSQL, I used to use it in Access and now need to run something like that in TSQL. Simply getting unique ID with first forename and surname, cause there are some dupes in a table.
There are records like:
ID forename surname -------------------------------- 1 John Kormack 1 James Dope 2 Erin Dupes 3 Will Hugh 3 Walter Heisenberg
WITH summary AS (SELECT tu.SequenceNumber, tu.trialid, tu.SBOINumber, tu.DisplayFlag,
[Code] ....
I am having trouble with the RowNumber Over Partition By portion of the query. I would like the query to return only the first occurrence of each sboinumber in the table for each trial id. It is only giving me the first occurrence of each sboinumber. I tried including the trialid in the partition by clause, but that is not working.
How do I select where two columns are the same, but the remaining columns might be different? For example, if I have 4 columns: First, Last, Class, and Year. I want a listing of First, Last, Class and Year but only if the same First, Last has > 1 row (ie that the same person is in the table twice.)
What is the most efficient way to write an SP to tackle all kinds of combinations here (where a user could give any search input).I know this must be fairly common to come across this situation.I have written an SP which will take in all the parameters and based on "IF" statements and using "LIKE" in SQL, this SP returns search results.But I wanted to know if there was more efficient ways of doing this, as you can imagine you might end up having several combinations of IF conditions.
I have a view in my database detailing the expiry date of each credential for each employee. The view is designed as to display one record per employee and in that record is the expiry date of each credential and the days remaining. So the columns are as follows:-
Employee CodeExpiry Date (x8 columns) (named as credential e.g. [Passport]) Days Remaining (x8 columns) (named as "TS_" + Credential)
I'm trying to use the CASE function to compare each DATETIME column with one another and retrieve the minimum. How can I return the minimum date as a run-time column and sort the view by this column? My code is as follows:-
SELECT [Passport],[TS_Passport],[Visa],[TS_Visa],[Civil_ID],[TS_Civil_ID],[KOC_Pass],[TS_KOC_Pass],[JO_Pass],[TS_JO_Pass], [Ratqa_Pass],[TS_Ratqa_Pass],[Driving_License],[TS_Driving_License],[Health_Book],[TS_Health_Book], CASE WHEN Passport <= Visa AND Passport <= Civil_ID AND Passport <= KOC_Pass AND Passport <= JO_Pass AND
[code]....
I've been told that this is the most efficient given the number of records in my database. The Min_Date is always NULL. I need the minimum of the 8 dates to be the Min_Date.
1 2015 ba1 137 HL EL Eco 2 2015 ba1 138 EL SL HS 3 2015 ba1 139 SL EL His
From this table i use to admit a student and select their choice of group simultaneously all the subjects associated with GROUP is save on another table.
Here is the TABLE 2 Structure and sample data:
table 2 (NAME - tblstudetail)
id studentID session course sub1 sub2 sub3
1 15120001 2015 ba1 EL SL HS 2 15120002 2015 ba1 HL EL Eco 3 15120003 2015 ba1 SL EL His 4 15120004 2015 ba1 HL EL Eco
AND so no..........................
Now i just want to COUNT the Number of Groups Filled in tblStudateil.
I am using SQL 2012. I have a GROUP BY and I want to select two other fields from my table at the same time: One column that is a string (account_code) and one that I need to perform a count on (customer_number). I know the code COUNT(DISTINCT customer_number) works for getting that. I need to select both of those fields on top of what I have. I have the following:
DECLARE @Providers TABLE (ID INT IDENTITY(1,1), Provider_Name VARCHAR(20), Uniq_Id VARCHAR(10), Total_Spent MONEY, Total_Earned MONEY) INSERT INTO @Providers (Provider_Name, Uniq_Id,Total_Spent, Total_Earned)
In a table I have some rows with flag A & B for a scode, some scode with only A and some are only B flags.
I would like to fetch all rows with flag A when both flags are present, no rows with B should be fetched. Fetch all rows when only single flags are present for a scode.How to achieve this using TSQL code.
SELECT ID1, ID2, type, (case when type = '1' then sum(value) else '0' end) as Value1, (case when type = '3' then sum(value) else '0' end) as Value2, (case when type <> '1' and type <> '3' then sum(value) else '0' end) as Value3 FROM table1 WHERE ID1 = 'x' and ID2= 'y' GROUP BY ID1, ID2, Type
