Oracle SQL-免费文本搜索

Question

I'm implementing a kind of Catalog Search (Item Search), but I want to support searches with partial information, specially to support searches with Item Description, so users could type in part of the Item Description.

I want to support something like:

port = S port s
sup port
Port
port able

123 = NES89- 123 9989
123 9948993HD-08
767-OIJD-189 123 -09OI

Any ideas?

Thanks.

Answer 1

Use "like" comparison.

example:

select *
from tbl
where my_data like '%port%';

Answer 2

如果要搜索的列称为TXT ，并且输入字符串是名称为:SEARCH_STR的绑定变量，则需要在查询中包括WHERE INSTR(TXT, :SEARCH_STR) > 0 。
