<p>The Change Dynamic Default Collection (QSQCHGDC) API defines a default
|
||
|
|
collection for unqualified table names in dynamically prepared statements or in
|
||
|
|
dynamically executed statements. The default collection is defined only for the
|
||
|
|
job issuing the API call. The default collection will take precedence over the
|
||
|
|
naming convention and default collection specified when the SQL program was
|
||
|
|
created.</p>

<h3>Usage Notes</h3>

<ol>

<li>If a package is created with a DFTRDBCOL, QSQCHGDC has no effect.<br>

group scoped.</li>
