Re: embedded sql and object_statistics

Ah - didn't see that the quotes are in the string - so if the string contains something like 'OBJ1', 'OBJ2', 'OBJ3' the following code should work:

...
where objname in (
select trim(trim(element), '''')
from table(systools.split('XXX, YYY', ','))
)
...

The split() creates the result table - the inside trim() removes potentially spaces - and the outside trim() removes the quote characters.

The way to dynamic SQL should always be the last resort - because dynamic SQL is not optimizable at compile time.

Dynamic SQL will probably be your best bet.

This is what you mentioned using:



select on qsys2.object_statistics, and my

Where objname in (:l_objects)

You also mentioned l_objects containing "'OBJECT1', 'OBJECT2'"

IN does not work like this over a variable.


You are basically doing this:



select * FROM TABLE(QSYS2.OBJECT_STATISTICS(…)) X

Where OBJNAME in ( '''A'',''B'',''C'',''D''' )


The SPLIT didn’t work because you are including the single quote inside your L_OBJECTS string.

If you used Dynamic SQL then you could build the statement as you expected it to work.

If you stay with Static and stop adding the quotes into your string then the split will work.
Split would work if the string contained “OBJECT1, OBJECT2, OBJECT3” without the quotes.


If you don’t want to use Split, and keep the quotes then you can use POSITION like this:

WHERE Position( '''' || TRIM(OBJNAME) || '''' IN :L_OBJECTS ) > 0
