Hi,
My application accesses DB2 over DB2 CLI and we use the calls
SQLTables, SQLTablePrivile ges, SQLColoumns to retrieve the schema
information from the system catalog tables. When we call SQLTables
when using the DB2 Connect Client v7.1.0.40, the call results in the
following query
SQLTables( hStmt=1:1, szTableQualifie r=Null Pointer,
cbTableQualifie r=0, szTableOwner="P 390", cbTableOwner=-3,
szTableName="%" , cbTableName=-3, szTableType="TA BLE", cbTableType=-3 )
---> Time elapsed - +1.045900E-002 seconds
( StmtOut.=" SELECT CREATOR, NAME, TYPE, REMARKS,
TBCREATOR,TBNAM E,LOCATION FROM "SYSIBM".SYSTAB LES WHERE CREATOR='P390'
AND CREATOR<>'SYSIB M' AND TYPE='T' ORDER BY 3, 1, 2 FOR FETCH ONLY" )
Our customer was seeing a huge delay when our application was loading
the schema on his production system. It turns out that they are using
the DB2 v7.1.0.93 (Fixpack 11) of DB2 Connect Client on Win2K. This
version uses RTRIM in the SQL call resulting from the application call
to SQLTables. (The 7.1.0.40 does not use RTRIM)
Is there any way I can setup the Connect client so that the RTRIM
function is not called? The DB2 DBA at the client end say that the use
of RTRIM prevents the use of indices, which will obviously impact
performance. Do you have any pointers for this?
Regards
~Rashmi

Hi,
This is my rtrim version:
inline void rtrim(string *ptr_s)
{
string::reverse_iterator rit= ptr_s->rbegin();
while(rit != ptr_s->rend() && *rit==' ') ptr_s->erase((++rit).base());
}

Hi,
i am using Postgres 7.4.2 with jdbc. Every time i try to select a
varchar the SQL generated by the jdbc driver uses RTRIM(t0.columnname)
which breaks an existing application. Is this normal, can we disable
the RTRIM usage?

Hi,
I have erronous white space at the end of my 'description' field within my
'product' table. I tried using the RTRIM function but it won't let me
because it is a TEXTBLOB (text) field.
Can anyone show me how to write a query that will update all my rows
automatically?
I'm using SQL Server 2000.

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
