Valid For
Extract and Replicat
Description
Use the TRIMVARSPACES
and NOTRIMVARSPACES
parameters to control whether or not trailing spaces in a source VARCHAR
column are truncated when applied to a target CHAR
or VARCHAR
column. TRIMVARSPACES
and NOTRIMVARSPACES
can be used at the root level of the parameter file as global ON/OFF
switches for different sets of TABLE
or MAP
statements, and they can be used within an individual TABLE
or MAP
statement to override any global settings for that particular MAP
or TABLE
statement.
The default is NOTRIMVARSPACES
because the spaces in a VARCHAR
column can be part of the data. Before using TRIMVARSPACES
, make certain that trailing spaces are not required as part of the target data.
For Extract, TRIMVARSPACES
only has an effect if Extract is performing mapping within the TABLE
statement (by means of a TARGET
statement).

Examples
The following example uses TRIMVARSPACES
and NOTRIMVARSPACES
at the root level of the parameter file. The default of NOTRIMVARSPACES
is in effect until the last MAP
statement, to which TRIMVARSPACES
applies.
MAP fin.src1, TARGET fin.tgt1; MAP fin.src2, TARGET fin.tgt2; MAP fin.src3, TARGET fin.tgt3; TRIMVARSPACES MAP fin.src4, TARGET fin.tgt4;
The following example uses TRIMVARSPACES
within a MAP
statement to override the global default of NOTRIMVARSPACES
. The default applies to the first two MAP
statements, and then TRIMVARSPACES
applies to the last two targets.
MAP fin.src1, TARGET fin.tgt1; MAP fin.src1, TARGET fin.tgt2; MAP fin.src1, TARGET fin.tgt3, TRIMVARSPACES; MAP fin.src1, TARGET fin.tgt4, TRIMVARSPACES;
