SYBASE ASE 15.0.2 – Case Sensitive to Non-Case Sensitive

SYBASE ASE 15.0.2 – Case Sensitive to Non-Case Sensitive.

Sybase ASE database by default is case sensitive. But Oracle is not. We are testing one application with SYBASE ASE 15.0.2 developer edition where we will be having a data from Oracle RDBMS which needs to be replicated to ASE. That raw data is non-case and it's in various forms. To avoid more re-work as this is an immediate testing so we planned to test this.

I tried few sites which I could not able to get the resource and after browsing Google my search ended with infocenter.sysbase.com.

1; select @@version

2; go


Adaptive Server Enterprise/15.0.2/EBF 14336/P/x86_64/Enterprise

Linux/ase1502/2486/64-bit/FBO/Thu May 24 08:06:35 2007

I Here is the procedure I used to find the default sort order of the database which is 25, Binary ordering for UTF-16.

1; sp_helpsort

2; go


Sort Order Description


Character Set = 190, utf8

Unicode 3.1 UTF-8 Character Set

Class 2 Character Set

Sort Order = 25, binary

Binary ordering for UTF-16

(return status = 0)

The are two ways to approach this one is via server console on a Unix system with sqlloc or with sp_configure. I preferred to go with sp_configure as I will always have control of what I am doing. This is a test purpose and I did not bother to dump the database. So FULL DATABASE is must, whenever we do configuration changes, always makes us on safer sideJ.

2; select s1.value2

3; from syscurconfigs s1, sysconfigures s2

4; where s1.config = s2.config

5; and s2.name = 'configuration file'

6; go




Take a copy of the Configuration file before you proceed further. It helps us to know what we have before system changes.

4; sp_configure "default sortorder id", 52

5; go

You have just reconfigured ASE's default sort order. System table indexes will be rebuilt when you reboot ASE.

Parameter Name Default Memory Used Config Value

Run Value Unit Type

------------------------------ ----------- ----------- ------------

------------ -------------------- ----------

default sortorder id 50 0 52

25 id static

(1 row affected)

Configuration option changed. Since the option is static, Adaptive Server must be rebooted in order for the change to take effect.

Changing the value of 'default sortorder id' does not increase the amount of memory Adaptive Server uses.

(return status = 0)

Shutdown the ASE Server…

1; shutdown

2; go

Server SHUTDOWN by request.

ASE is terminating this process.

Start the ASE Server

Once you bring the ASE server it will check for consistency and it will rebuild all the indexes.
