在 Sybase IQ 中使用 LIST 和排序 - 多个 LIST 选择抛出 "ORDER BY"？
Using LIST and sorting in Sybase IQ - multiple LIST selects throws off "ORDER BY"?
我的查询类似于...
LIST( column1, " ;" ORDER BY column2)
这行得通。当我在 SELECT 中添加更多 LIST 函数时，ORDER BY 将被忽略。任何人都知道为什么会发生这种情况？我想避免单独进行联合或 运行 查询然后加入
文档表明对使用多个 ORDER BY 子句有限制：
"A query block containing more than one aggregate function with valid ORDER BY clauses can be executed if the ORDER BY clauses can be logically combined into a single ORDER BY clause."
