sql - How do I execute a sequence of DB2 queries with a loop in the middle of them? -

-

i have been rolling around issue couple of days now. converting unix script uses sybase run in db2 instead , there loop in middle of it.

the script contains several temp tables , update statements reliant came before it... followed loop , few more temp tables, update statements, etc... before query @ end populates end result , exports spreadsheet.

the issue have can declare, insert, update, , select query blocks run @ same time. however, when try run @ once loop in middle, following error: " sql0104n unexpected token "end-of-statement" found following "ssion.min_assessment". expected tokens may include: "join ". line number=1. sqlstate=42601".

the blocks run fine when ran individually... need of blocks run can place them in unix script scheduled.

the structure looks this:

declare temp_table_a; insert temp_table_a (select ... <table> ...); declare temp_table_b; insert temp_table_b (select ... temp_table_a, <table> ...); update temp_table_b set <field> = (select <field> <table> ...); delete temp_table_b ...; declare temp_table_c; declare temp_table_d; begin atomic    v1        select ... temp_table_b           delete temp_table_c;        insert temp_table_c (select ...);        delete temp_table_b exists (select 1 temp_table_c);        update temp_table_d set <date_field> = temp_table_c.<date_field> exists (select 1 temp_table_b ...);        delete temp_table_c exists (select 1 temp_table_c ...);        insert temp_table_d select ... temp_table_c;    end for;  end declare temp_table_e; insert temp_table_e (select ... temp_table_d, <table> ...); update temp_table_e set <field> = (select <field> <table> ...); select ... temp_table_e;

does have ideas can of query blocks run in sequence , include loop?

first, need put declare @ beginning. then, in order control execution use handler , variable, or fetching each row in for.

C# random value from dictionary and tuple -

i have following code, , need random item contains string "region_1" dictionary. public static dictionary<int, tuple<string, int, currencytype>> itemarray = new dictionary<int, tuple<string, int, currencytype>>() { { 0xb3e, new tuple<string, int, currencytype>("region_1", 1500, currencytype.fame) } }; public static int generateitemid(string shopid) { var generateditem = itemarray.elementat(new random().next(0, itemarray.count)).key; } how select this? it's not possible efficiently... first create static random @ class level... prevent non-random behaviour if run query on short period of time... (it's seeded discrete clock) static random rnd = new random(); then: var item = itemarray.values .where(t => t.item1 == shopid) .orderby(_ => rnd.next()) .firstordefault()

so i'm trying install zoneminder , have run under nginx, has few compiled files need run using fast-cgi. these files lack extension. if file has extension, there no issue , nginx interprets file , return 404 if can't find it. if has no extension, assume it's directory , return 404 when can't find sort of index page. here have now: # security camera domain. server { listen 888; server_name mydomain.com; root /srv/http/zm; # enable php support. include php.conf; location / { index index.html index.htm index.php; } # enable cgi support. location ~ ^/cgi-bin/(.+)$ { alias /srv/cgi-bin/zm/; fastcgi_pass unix:/run/fcgiwrap.sock; fastcgi_param script_filename $document_root/$1; include fastcgi.conf; } } the idea is, under cgi-bin directory goes through fastcgi pipe. any idea on howi can fix this? upon closer inspection, realized zoneminder has 2 cgi sc...
