我正试图从一封信一字的一张桌上挑选(例如a-f)
我尝试了这样的条款:

以上所述并不可行。 任何想法,我会错做什么?

http://www.postgresql.org/docs/8.3/static/Functions-matching.html。 SIMILAR TO keyword. 下面列出所有标题,从一、k或t开始。
... WHERE lower(title) SIMILAR TO (a|k|t)%

<>0>
<>%>>>> > 代码/代码”的特性与格式相应的任何特性。 例如,第二种模式的范例是:bc、ab、a、w、w、恐惧等。
此外,必须指出<代码>。 SIMILAR TO keyword is only available to PostgreSL and it is not ANSIQ.
最后,在使用特性类别时,不需要<代码>底线(标题)代码>。 你们只能寻找像样的东西。
