> Query such as
> {code:sql}
> SELECT g_0.intkey FROM bqt1.smalla g_0 UNION SELECT g_1.intkey FROM bqt1.smallb g_1 LIMIT 100
> {code}
> fails with
> {noformat}
> [PIOLEDBENT] [SQL Parser] [Line 1:106] Syntax error at 'TOP'
> {noformat}
> because it is translated as
> {code:sql}
> SELECT g_1.IntKey AS c_0 FROM dvqe..SmallA AS g_1 UNION SELECT g_0.IntKey AS c_0 FROM dvqe..SmallB AS g_0 TOP 100
> {code}
> notice the TOP 100 at the end, instead of right after the SELECT.
