Are there any other fields in MYTABLE? Particularly a unique key?

with unpivot as (
select key, varchar(element, 15) as f1
from mytable, table(systools.split(myfield1, ';'))
)
select *
from mytable1 t1
where t1.key in (select u.key from mytable2 t2 inner join unpivot u on u.f1
= m2.flda)

If there's no unique key, you could use RRN.

Generally, you don't want to create a temporary table unless you have
multiple processes running over it.
Yes, this will take more memory, but usually less time.

I have a Table (MYTABLE1) with millions of rows with a field FLD1 (256
chars). I have another table (MYTABLE2) with about 100 rows with a field
FLDA (15 chars).

I want to get all records from MYTABLE1 where FLD1 has FLDA.
If FLDA has a value of 'ABCD' then
Select * from MYTABLE1 where FLD1 like %ABCD%
would probably do the job. But I need to do it for FLDA values of all the
records in MYTABLE2.

I know I haven't explained it properly so let me give an example:

FIELD1 in MYTABLE1:
Row 1 - ABCDEF;123456;GH;78
Row 2 - CDEFG;345678;
Row 3 - 345678;EWRT;9888
Row 4 - 85465;ASDFGT;QWERTY;85656

FLDA in MYTABLE2:
Row 1 - 123456
Row 2 - 345678

The final sql should return Rows 1,2,3 from MYTABLE1.

TIA
Vinay
