<div><p>Due to limitations in iSeries™ <span class="keyword">i5/OS™</span> releases
|
|
prior to V5R2M0, using the iDB2CommandBuilder on these servers has limited
|
|
support.</p>
|
|
<div class="section"><p>Properly specifying Select command text on the iDB2Command object
|
|
used with the iDB2CommandBuilder is key when connecting to pre-V5R2M0 servers.
|
|
Here are some recommended guidelines for creating Select statements for use
|
|
on pre-V5R2M0 servers. </p>
|
|
<ul><li>Simple statements produce the best results. For example, SELECT * FROM
|
|
MYSCHEMA.MYTABLE. </li>
|
|
<li>Fully qualify the table name with its schema. For example, MYSCHEMA.MYTABLE. </li>
|
|
<li>Selection fields are allowed, but must be specified in simple format.
|
|
Only columns specified in the query table should be used. For example, SELECT
|
|
ID, NAME, BALANCE FROM MYSCHEMA.MYTABLE. </li>
|
|
<li>Derived fields or constants in the selection criteria are discouraged.
|
|
They may produce unpredictable results. For example, SELECT ID, LENGTH(NAME),
|
|
'Name' FROM MYSCHEMA.MYTABLE.</li>

|
