仅将FETCH FIRST 1行放入在FOR READ ONLY之前和OPTIMIZE FOR 1

ROW。


" FETCH FIRST 1 ROW ONLY"是Subselect的一部分。

FOR READ ONLY和优化1行是select-sttement的一部分。

Put "FETCH FIRST 1 ROW ONLY" before "FOR READ ONLY" and "OPTIMIZE FOR 1
ROW".

"FETCH FIRST 1 ROW ONLY" is part of Subselect.
"FOR READ ONLY" and "OPTIMIZE FOR 1 ROW" are part of Select-sttement.

即使这不起作用。

Even this does not work.
