how to split a large table consisting of a single column with 15 attributes, there should be 15 columns. in MsSQL server. Thanks 😊!

[@LearnatKnowstar]

There can be different approaches. One way can be to use string split function. Please see detailed tutorial here -

@@LearnatKnowstar thanks 😊

[@pareshyadnik4108]

can we use parse name function to split the string or there is a performance issue

[@pickmeisha]

My field is 'Doe,John A' and I am trying to partition the A...this is not working as it pulls over the entire name when there is no middle initial.

[@raj-sk4br]

What about middle name?

[@LearnatKnowstar]

If there is always a middle name, you can use charindex to extract the middle string. If the middle name might or might not exist, then more logic needs to be put in the SQL query.

[@LearnatKnowstar]

Thanks for presenting this scenario. We will post a solution video soon.

[@solomong.gebrhana1204]

what if we have 4 strings to extract? what is the best function to use?

[@YouCallThataKnife253]

What if I no longer want to see that original concatenated column?

[@prashantdahiya711]

Thank you Mam, 👍

[@LearnatKnowstar]

Glad it was helpful 🙏

[@tanyagupta6319]

How many possibilities these SQL queries will come in the placement? I mean same as it came ya little bit differ has to be come?

[@Hakeem_Abdul]

Can you pls help me with a similar request.?? My need is: if length of input field is more than 40 characters, then it should load data until last space before 40 characters to one column and the remaining should load to another column..

[@Dracometeor562]

is this supported at SQL 2005 ?

[@LearnatKnowstar]

Yes, it is.

[@NaveenKumar-fq4sb]

where is data set ...

[@Faisal1504]

What about the space between the , and first name? Don’t we add +1 to charIndex. ?

[@LearnatKnowstar]

Yes, you can do a +1 or apply trim on the extracted first name.

[@prashantx19]

what if there are three commas

[@LearnatKnowstar]

You can use string split function. See tutorial here

[@shubhamgoyal5227]

Hello mam if there is middle name then then could you please guide how to derive it e.g ram kumar bansal in this how can we derive kumar using sql query.

[@hnaidu.pro21]

Static Method (Name is Hardcoded):
SELECT SUBSTRING('Ram Kumar Bansal',
CHARINDEX(' ', 'Ram Kumar Bansal') + 1,
CHARINDEX(' ', 'Ram Kumar Bansal', 5) - CHARINDEX(' ', 'Ram Kumar Bansal', 1)) AS MiddleName
Dynamic Method (Applies to all names):
SELECT SUBSTRING([Name],
CHARINDEX(' ', [Name]) + 1,
CHARINDEX(' ', [Name], CHARINDEX(' ', [Name]) + 1) - CHARINDEX(' ', [Name], 1)) AS MiddleName
FROM TableName;

[@avinashkarad7141]

i am using 11g .. i have data like below in 1 column
col_name
1
john
34000
3
david
20000
want output like in 3 different columns like this
id name salary
1 john 34000
3 david 20000
pls help me with this @Learn at Knowstar

[@hnaidu.pro21]

Another Method: Using a Substring
SELECT EmployeeID, Name,
SUBSTRING([Name], CHARINDEX(' ', [Name], 1) + 1, LEN([Name])) AS FirstName,
SUBSTRING([Name], 1, CHARINDEX(',', [Name], 1) - 1) AS LastName
FROM [dbo].[tblNames]
Method 2: Using Reverse function (along with LEFT, RIGHT)
SELECT EmployeeID, Name,
RIGHT([Name], CHARINDEX(' ', REVERSE([Name])) - 1) AS FirstName,
LEFT([Name], CHARINDEX(',', [Name], 1) - 1) AS LastName
FROM [dbo].[tblNames]
