Re: Need SQL help

You need to have 5770-SS1 option 39 (International Components for Unicode)
installed to be able to use the REGEXP functions in SQL.

The function is REGEXP_INSTR - this requires at least 7.3, as well.

Good luck!

I ran this on the development box:
select *
from mytable1
where regex_instr(myfield1,
select listagg(trim(flda),'|') from mytable2
)> 0

I got error "REGEX_INSTR in *LIBL type *N not found"

I gave you two different single SQL statements...

But if you can actually use SQL, I don't know why you'd ask for it.

They use sql interface SEQUEL software (by fortra) , which does not

doing

this

with a single sql statement, I can try to see if it can be done in

SEQUEL.

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
