Hey there, SQL enthusiasts! Have you ever encountered a situation where you’ve imported a CSV file into SQL Server, only to realize that one of your columns contains a list of values? Yeah, I’ve been there too.
Let’s say you’ve got a table that looks like this:
Url | Id | amount | date
X.com | [1,2,3,4] | 12.3 | 11/22/21
T.com | [,4] | 13 | 11/22/21
P.com | [1,2,3,4] | 12 | 11/22/21
J.com | [1,2,3,4,6,7] | 1.3 | 11/22/21
The goal is to break down the Id column into separate rows, assigning one Id per entry. For instance, the first row should become four rows with four Ids each.
Url | Id | amount | date
X.com | 1 | 12.3 | 11/22/21
X.com | 2 | 12.3 | 11/22/21
X.com | 3 | 12.3 | 11/22/21
X.com | 4 | 12.3 | 11/22/21
So, how do you go about achieving this? Well, I’ll share some insights and potential solutions in this post.
