Alternatives: Special Chars in German with REGEXP (Spezialzeichen in Deutsch - eine Alternative) 🔗

select peid
, trim(replace(replace(replace(upper(name),'Ö','OE'),'Ä','AE'),'Ü','UE')) as name
, trim(replace(replace(replace(upper(vorname),'Ö','OE'),'Ä','AE'),'Ü','UE')) as vorname
, geb_Gruend_Datum as gebdat
,'x' as geschl
from daten

CREATE INDEX i_nls_1 ON daten(NLSSORT(name, 'NLS_SORT=XGERMAN_AI'));
CREATE INDEX i_nls_2 ON daten(NLSSORT(vorname, 'NLS_SORT=XGERMAN_AI'));

-- match auf nur erster vorname, eindeutig
WHERE a.vorname = regexp_substr(l.vorname,'^[a-zA-Z]*')

-- match auf nur erster name, eindeutig
WHERE regexp_substr(a.name,'^[a-zA-Z]*') = regexp_substr(l.name,'^[a-zA-Z]*')

-- match auf nur erster name und erster vorname, eindeutig
WHERE regexp_substr(a.name,'^[a-zA-Z]*')    = regexp_substr(l.name,'^[a-zA-Z]*')

-- match auf soundex erster name und erster vorname
WHERE soundex(regexp_substr(l.name,'^[a-zA-Z]*'))
    = soundex(regexp_substr(a.name,'^[a-zA-Z]*'))

-- match auf zweiter vorname(X) auf erster vorname(Y) !
WHERE regexp_substr(l.name,'^[a-zA-Z]*') = regexp_substr(a.name,'^[a-zA-Z]*')

-- match auf irgendwas ähnliches (something similiar, almost similiar)
WHRERE regexp_like(a.vorname,l.vorname)

Update on Oracle g Database Features for Linguistic Sorting and Query Functions 🔗

Oracle g Database introduced many new features for case accent and linguistic independent query and sort functions back in 2011. These features were highly beneficial for SQL and PL/SQL developers, enabling them to search for almost similar string matching and set up linguistic sorting easily.

As of the year 2024, the relevance and importance of these features have only increased. With the ever-growing globalization and diversity in data, linguistic sorting and query functions play a crucial role in ensuring accurate and efficient data retrieval and organization.

In the current technological landscape, where data is vast and varied, the capability to perform linguistic sorting in different languages, such as German, remains a valuable asset for organizations using Oracle g Database.

The original functionalities like altering sessions to enable linguistic sorting and case-insensitive searches are still applicable and widely used by developers. The ability to create indexes with specific linguistic sorting rules, like NLS SORT XGERMAN AI, continues to enhance database performance and data retrieval efficiency.

Moreover, the use of REGEXP for handling special characters in German text provides a flexible and powerful way to manipulate and query data, ensuring accurate results even with complex linguistic requirements.

For SQL and PL/SQL developers working with Oracle g Database in 2024, the documentation and resources provided by Oracle, such as the Oracle Docs and Oracle Support, remain valuable sources of information for leveraging linguistic sorting features effectively.
