Re: curly braces to group outer joins in queries from

What about the `OJ'?

FROM ( OJ table alias left join table2 alias2 )

OJ seems plain wrong, right?

Here's their code snippet (from
oo_1.1_src/dbaccess/source/ui/querydesign/QueryDesignView.cxx):

if(aJoin.getLength())
{
::rtl::OUString aStr = ::rtl::OUString::createFromAscii("{ OJ ");
aStr += aJoin;
aStr += ::rtl::OUString::createFromAscii(" },");
aTableListStr += aStr;
}

You mean simple parathesis, no `OJ' would be OK?

like:

@@ -1141,9 +1141,9 @@

if(aJoin.getLength())
{
- ::rtl::OUString aStr = ::rtl::OUString::createFromAscii("{ OJ ");
+ ::rtl::OUString aStr = ::rtl::OUString::createFromAscii("( ");
aStr += aJoin;
- aStr += ::rtl::OUString::createFromAscii(" },");
+ aStr += ::rtl::OUString::createFromAscii(" ),");
aTableListStr += aStr;
}

Thanks for the prompt reply, as usual!
