问题 SQLFIddle link for this data. Suppose I have a table with following Structure: create table rd(r1 number,r2 number, primary key (r1,r2)); Sample Data: | R1 | R2 | ----------- | 1 | 2 | | 1 | 4 | | 2 | 3 | | 3 | 1 | | 4 | 5 | What it means is that R1 is related to R2 , bi-directionally. So if there is an entry in database for 1,3 there won't be an entry like 3,1. According to above data: 1 is related to 2,4,3 directly. And 4 is related to 1 also . So via transitive dependency, 1 and 5 are also

Change NLS Character set parameters on Oracle 11g XE

由 倾然丶 夕夏残阳落幕 提交于 2019-12-06 04:09:28
问题 I am using Oracle 11g Express Edition. Currently when I check NLS character set parameter using SELECT * FROM nls_database_parameters; it gives the default values: NLS_CHARACTERSET: AL32UTF8 NLS_NCHAR_CHARACTERSET: AL16UTF16 I want to set both these parameters to UTF8. How can I do so? I have just installed Oracle 11g XE, so there is not data except those required by Oracle itself. 回答1: This worked for me where an application was checking for UTF8 rather than AL32UTF8 .

Search for similar words using an index

由 廉价感情. 提交于 2019-12-06 02:55:16
I need to search over a DB table using some kind of fuzzy search like the one from oracle and using indexes since I do not want a table scan(there is a lot of data). I want to ignore case, language special stuff(ñ, ß, ...) and special characters like _, (), -, etc... Search for "maria (cool)" should get "maria- COOL" and "María_Cool" as matches. Is that possible in Oracle in some way? About the case, I think it can be solved created the index directly in lower case and searching always lower-cased. But I do not know how to solve the special chars stuff. I thought about storing the data without
