Here is an overview of the issue:
---------------------------------------------------------------------
Key: HB-447
Summary: SAPDB hangs with big strings.
Type: Bug
Status: Unassigned
Priority: Minor
Project: Hibernate2
Components:
core
Versions:
2.0.2
Assignee:
Reporter: the_Ellessar
Created: Mon, 3 Nov 2003 2:44 AM
Updated: Mon, 3 Nov 2003 2:44 AM
Environment: Sapdb 7.4, Linux red hat 9
Description:
I'm having a problem with SapDB and long strings. It is probably a bug in SapDB (driver) but I made an easy fix in the sapdb dialect.
According to the SapDB documentation it is possible to put dat with a length 8k in a VARCHAR field, but when I define a string with length bigger than 1024 SapDB becomes REAL slow.
As far as I know the clob type doesn't work very well with the SAP JDBC driver.
So I created the next patch:
Index: SAPDBDialect.java
