sql - join 78 specific codes from created table to linked table. Can't use IN() function (character limit), Can't do RI -


i have db (access 2010) pulling data from, trying make easier pull specific cases instead of mucking in excel.

we have 78 product type codes classify account type. unfortunately can't use in() function because there many characters (there 1024 char limit). looked online , suggested make table inner join on product codes want.

i created table codes want pull, joined on productcodetype in linked database table. unfortunately when run sql nothing shows up, blank. tried different join combinations no avail, read further , found can't enforce referential integrity on linked db tables non-linked db tables.

i think problem i'm not sure, , don't know if i'm using right language, can't find similar issue mine i'm hoping it's easy fix , i'm not thinking right way.

is there way select cases (78 product type codes) large database using in() or reference table when can't create new table in linked db?

thank you, k

you must use 2 tables , build query join them. if join don't return result, sure joined fields of same data type , realy share same values.

if data source excel, sure there isn't trailing blanks or other 'invisible' character.

java - IntelliJ - No such instance method -

using intellij's 12 ultimate, i'm running following code in debugger: java import play.api.libs.json.jsvalue; public class foo { ... public jsvalue tojson() { ... } public class fooexample { ... foo foo = new foo(); system.out.println("...); //<-- breakpoint at breakpoint, right-clicked source code , picked "evaluate expression," typing in: foo.tojson() . but following error showed up: no such instance method: play.api.libs.json.jsvalue$class.com.foo.foo.tojson () am doing wrong? foo#tojson calls scala code, if matters. edit had breakpoint after instantiation of foo. downvoted it, deserved it. edit my answer no longer valid after op modified question (i.e. moved breakpoint actual is).. a breakpoint hit before line executed. in case foo has not yet been declared or instantiated (i.e. foo constructor has not yet been called). you'll need put breakpoint @ next line (or step on current line) if want evaluate foo .

identifier - Is it possible for an html5 document to have two ids? -

i wondering if html5 element can have 2 ids, this: <button id="thing1" id="thing2" name="button1" onclick="change()">click here</button> or this: <button id="thing1, thing2" name="button1" onclick="change()">click here</button> also, if 1 of ids said 1 thing, , other id said thing, 1 used? tl;dr : no. in versions of html, each element can have 1 id. see the spec : the id attribute specifies element's unique identifier (id). [dom] the value must unique amongst ids in element's home subtree , must contain @ least 1 character. the value must not contain space characters. note: there no other restrictions on form id can take; in particular, ids can consist of digits, start digit, start underscore, consist of punctuation , etc. note: element's unique identifier can used variety of purposes, notably way link specific parts of document usin
