Transact SQL :: Find Unmatching Columns Between Two Tables While Applying A Change Column Prefix Table

Nov 16, 2015

For our ETL process, we maintain a TransformationList table that has the source view and the destination table. Data is copied from the view into the table (INSERT INTO). I am trying to find column names in the Views that are not column names in the associated Table.

In the below example, want to end up with three records:

 1, View1, Column4
 2, View2, Column4
 2, View2, Column5

I have it almost working, except that there is a table, ChangeColPrefix table, that is used by the ETL process to change some of the view's column name prefixes. Some of the source views have column names with prefixes that do not match the destination table column names. Say view SouthBase has all the column names prefixed with SB - like SBAcct, SBName. And the Destination table of Area District has ADAcct, ADName. There would be a row in the ChangeColPrefix for SouthBase, SB, AD, 1, 2 that would be used by the ETL process to create the INSERT INTO Area District From SouthBase.

I need to use this ChangeColPreifx to find my unmatching columns between my source views and destination tables. With out that table SBAcct and SBName from SouthBase will not appear to match the columns of ADAcct and ADName, but they do match.

I want to end up with these three records as non-matching:

View1, Column4
View2, Column4
View2, Column5

View1 has Salumn2 and View2 has Salumn5, and they must be changed to Column2 and Column5 as per the ChangeColPrefix table before running the Select from INFORMATION_SCHEMA.COLUMNS EXCEPT Select from INFORMATION_SCHEMA.COLUMNS looking for unmatched columns.

/***** Set Up Test Data *****/
-- Create 2 test views
IF EXISTS(SELECT * FROM sys.views WHERE object_id = OBJECT_ID(N'[dbo].[View1]'))
DROP VIEW dbo.[View1]
GO
CREATE VIEW View1
AS SELECT '1' AS Column1 , '2' AS Salumn2 , '4' AS Column4;

[Code] ....

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.

Transact SQL :: Adding New Columns To Server 2012 Table

Apr 28, 2015

I am planning to add some new columns to an existing sql server 2012 table. I know that I need to use the alter statement to accomplish this goal. However my questions is the location of where I want to add the new columns to the table. It would make more sense to add the new columns to the middle of the table since these columns have a similar meaning as other columns in the middle of the table.However is it better to add these new columns at the end of the table? I am asking this question since I am thinking I might need some sql to move the values of existing columns and values around?Thus is it better to add new columns to a table in the middle of the table, at the end of the table, or at the end of the table? If so, can you tell me why one location is better than another location?

Transact SQL :: Find Missing Months In A Table For The Earliest And Latest Start Dates Per ID Number?

Aug 27, 2015

I need to find the missing months in a table for the earliest and latest start dates per ID_No.  As an example:

create table #InputTable (ID_No int ,OccurMonth datetime)
insert into #InputTable (ID_No,OccurMonth) 
select 10, '2007-11-01' Union all
select 10, '2007-12-01' Union all
select 10, '2008-01-01' Union all
select 20, '2009-01-01' Union all
select 20, '2009-02-01' Union all
select 20, '2009-04-01' Union all
select 30, '2010-05-01' Union all
select 30, '2010-08-01' Union all
select 30, '2010-09-01' Union all
select 40, '2008-03-01'

For the above table, the answer should be:

ID_No OccurMonth
----- ----------
20 2009-02-01
30 2010-06-01
30 2010-07-01

1) don't include an ID column,

2) don't use the start date/end dates in the data or

3) use cursors, which are forbidden in my environment.

Transact SQL :: How To Bulk Insert Rows From Text File Into A Wide Table Which Has 1400 Columns

Feb 3, 2010

we can easily load a file into db tables. However, my main concern here is the number of columns in the file. A text file TEXT_1400.txt has 1400 columns. I am unable to load data to my db table using BCP or BULK INSERT commands, as maximum of 1024 columns are allowed per table in SQL Server 2008. 

We can still go ahead and create ‘Wide Table’ (a special table that holds up to 30,000 columns.  The maximum size of a wide table row is 8,019 bytes.). But when operating on wide table, BCP/BULK INSERT commands still fail. After few hours of scratching my head over BCP and BULK INSERT, I observed that while inserting BCP/BULK INSERT commands are unable to identify SPARSE columns and skip these columns, which disturbs column mapping and results in data conversion and trancation errors.
 
Is there any proper way to load this kind of files into the db table?

SQL 2012 :: Split Data From Two Columns In One Table Into Multiple Columns Of Result Table

Jul 22, 2015

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:

**TABLE_ONE**
Type Animal TestID
-----------------------------------------
Mammal Goat 1
Fish Cod 1
Bird Chicken 1
Reptile Snake 1
Bird Crow 2
Mammal Cow 2
Bird Ostrich 3

**Table_Two**
Test_name TestID
-------------------------
Test_1 1
Test_1 1
Test_1 1
Test_1 1
Test_2 2
Test_2 2
Test_3 3

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:

Test_Name Bird Reptile Mammal Fish
-----------------------------------------------------------------
Test_1 Chicken Snake Goat Cod
Test_2 Crow Cow
Test_3 Ostrich

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.

Open the connection again and do the ExecuteScalar() again. Theres got to be a better way of doing this.
