sql find exact string, NOT LIKE

[lukaxa]

i have table with two column

ID and groups.


ID: (1) (2) (3)
Groups: (2,12,21) (11,1,31) (43,44,144)


i want to find id with group 1, if i use "Like" , i am receiving every ID with number 1 in groups: 12,21,11,1,31,1 44.
answer will be (1) (2) (3)


i want just second ID with group number 1

ID (2)

maybe there is some Substring function, and i'm able to separate this values by ","

sorry for bad English

You are having so much trouble because your data is not normalized. It's poorly structured. Please read our article on normalization and then restructure your data.

this is not an option. this data is fixed and given from other person.

how can i normalize data?

there can be 2 group per user or 1000 group per user. i can't create columns for each one.

You don't create a column for each one. That's against normalization. You create a row for each id/group member. Given the data above, a normalized structure would have 2 columns and 9 rows. But you can't normalize your data so that's a moot point.

Your only option then is to build a custom parser using VBA code. You won't be able to do it using just SQL alone.

SELECT * FROM table WHERE GROUPS LIKE '%,1,%'

I think will do the trick...

@Basanth, that won't work because it doesn't separate the groups within the the field.
