|

|
|
value to another. This includes the assignment of host variables.

The database manager uses a common set of system services for converting SBCS
|
||
|
|
data, DBCS data, MIXED data, and graphic data.</p>
|

<div class="section"><p>The rules for CCSIDs are as follows:</p>
|
||
|
|
<ul><li>If the CCSID of the source matches the CCSID of the target, the value
|
||
|
|
is assigned without conversion.</li>
|
||
|
|
<li>If the sub-type for the source or target is BIT, the value is assigned
|
||
|
|
without conversion.</li>
|
||
|
|
<li>If the value is either null or an empty string, the value is assigned
|
||
|
|
without conversion.</li>
|
||
|
|
<li>If conversion is not defined between specific CCSIDs, the value is not
|
||
|
|
assigned and an error message is issued.</li>
|
||
|
|
<li>If conversion is defined and needed, the source value is converted to
|
||
|
|
the CCSID of the target before the assignment is performed.</li>
