Applies to

ODBC

OLE DB

Syntax

PBTrimCharColumns=value

Parameter

Description

value

Specifies whether PowerBuilder should trim trailing spaces from data of type Char, NChar, Text, NText, Char for Bit Data, VarChar, NVarChar, and VarChar for Bit Data. Values are:

  • NO

    (Default) Do not trim trailing spaces.

  • YES

    Trim trailing spaces.


Default value

'NO'

Usage

This parameter can only be set in the pbodb.ini file. For ODBC, you can set the TrimSpaces parameter in the Database Profile Setup dialog box or in code to perform the same function.

By default, PowerBuilder trims spaces from the following datatypes: Char, NChar, Text, NText, Char for Bit Data, VarChar, NVarChar, and VarChar for Bit Data.

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 PBTrimCharColumns='YES'.

Examples

To specify that PowerBuilder should trim trailing spaces, add the following line to the section for the database you are accessing:

PBTrimCharColumns='YES'
