Consider a CUSTOMERS table containing a mixed case CUSTNAME column.
To search it, many will use the UPPER() or LOWER() functions to mono case the
field like so:
Select * from customers
Where upper(custname) = upper(CustomerNameToFind)
However, this results in poor performance since an index canâ??t be used.
A better solution is to create a case insensitive index and perform your search
in a case insensitive
To create the case insensitive index, all you need to do is create the index
from a STRSQL or â??Run SQL
Scriptsâ?? session that is currently set to ignore case.
1) F13 â?? Services
2) Option 1 â?? Changes Session attributes
3) Change â??Sort Sequenceâ?? on the 2nd page to *LANGIDSHR
For iNavâ??s Run SQL Scripts
1) Connectionâ??JDBC Setup
2) Language Tab
3) Change â??Sort Based Onâ?? to Language ID
4) Make sure â??Sharedâ?? radio button under â??Sort Weightâ?? is selected
Now to make use of the indexâ?¦.
For interactive SQL , follow the same steps as above to switch your sessionâ??s
For a stored procedure, UDF, or embedded SQL, add the statement
SET OPTION SRTSEQ = *LANGIDSHR
For JDBC connections, add the follow to the connection string:
jdbc:as400://MYAS400;date format=iso;sort=language;sort weight=shared
