data values retrieved from the following datatypes: Char, NChar, Text,
NText, Char for Bit Data, VarChar, NVarChar, and VarChar for Bit
Data.

Default value
TrimSpaces=0 (ADO.NET, O90, O10, SNC, and IN9) or TrimSpaces=1
(DIR, ASE, and SYC). For JDBC, the default values depend on the
PBTrimCharColumns value in the registry. For ODBC, the default values
depend on the PBTrimCharColumns value in the PBODBnnn.INI file. (If the
PBTrimCharColumns keyword is missing for a particular database
connection, the default value for the ODBC interface is
TrimSpaces=0.)
Usage
By default, PowerBuilder trims spaces from the following
datatypes: Char, NChar, Text, NText, Char for Bit Data, VarChar,
NVarChar, and VarChar for Bit Data.
ODBC database interface
Some ODBC drivers, such as SQL Anywhere, trim trailing spaces
before the data reaches the fetch buffer — even when TrimSpaces is
set to 0.
If your DBMS makes a distinction between Char data with trailing
spaces and Char data without trailing spaces when evaluating a WHERE
clause expression, you might receive the message Row changed between
retrieve and update when your DataWindow object’s update properties are
set to “Key and updateable columns”. To prevent this, change your
DataWindow object’s update properties. In embedded SQL, you can check
Sqlca.Sqlnrows after each update to determine if the update took place.
Avoid using Char data columns in the WHERE clause of an UPDATE or DELETE
statement when TrimSpaces=1.
Examples
To specify that PowerBuilder should not trim trailing
spaces:
-
Database profile
Clear the Trim Trailing Spaces In CHAR Data check box on the
Syntax page in the Database Profile Setup dialog box. -
Application
Type the following in code:
1SQLCA.DBParm="TrimSpaces=0"
