Hello SQL Experts,
I have a question.... I have 3 tables (table1, table 2 and table3)
table1: table2
ID meat id type
1 beef pork 1 beef
2 pork chicken 2 chicken
3 pork chicken beef 3 beef
I have table3.
I am trying to write a t-sql querythat: first it will go to table1 and check for meat column, if the column has beef then it will go to table2 and then pick the ID corrosponding to beef and then add those 2 columns (table2.ID and meat) in table3. if the column has pork, chicken and beef this process should repeate 3 times and add the 3 rows in table3.
My question is how to get the data in meat column and check if it has pork and chicken (or) chicken, pork and beef etc..... is there any string function that I can use in T-SQL. (There is a space between 2 meats types in the meat column).
Please give me some T-SQL syantx for this.
Thank you all so much

We're going to want to see expected results if we're going to try to figure this out for you, unfortunately. It's a little odd. Also, if you can take a look at the first link in my signature, it will help you lay out the structure for us to help you.

Additionally, I assume you've tried to work through this already, please post your attempts so far.

EDIT: This screams either homework question or horrendous data layout. I'd like to know which we're dealing with.

How about:

select * into bbq

from table2

/*

result

-------------------

nom nom nom nom nom

(1 row(s) affected)

*/

Or, seriously, try looking at charindex and patindex in BOL - they should help you <to finish that homework>

Can you please list the structure and content of table 3, results? This will help define the question. Thanks.

try below code:

select t2.id,t1.meat

from table2 t2

cross join table1 t1

Where (case when t1.meat like '%'+t2.type+'%' then 1 else 0 end) = 1

order by t1.meat

Read the article at the first link in my signature line below. Try posting a bit of data and table structure that way and see the difference in how folks help you. 😉

RBAR is pronounced "ree-bar" and is a "Modenism" for Row-By-Agonizing-Row.
First step towards the paradigm shift of writing Set Based code:
________Stop thinking about what you want to do to a ROW... think, instead, of what you want to do to a COLUMN.

Change is inevitable... Change for the better is not.
