    <p>There doesn't appear to be an easy way to do it. I tried using the undocumented (as in I couldn't find it in the help docs but it is in the oci.h header) <code>OCI_ATTR_HANDLE_POSITION</code> using <code>OCIAttrGet()</code> on the bind handle:</p> <pre><code>ub4 bpos = 0; OCIBind *bindp; OCIAttrGet(bindp, OCI_HTYPE_BIND, &amp;bpos, 0, OCI_ATTR_HANDLE_POSITION, errhp); </code></pre> <p>Unfortunately, that seems to work for bind handles that you bound positionally, but return 0 for any you bound by name.</p> <p>So it seems like you would have to use the <a href="http://download.oracle.com/docs/cd/B19306_01/appdev.102/b14250/oci15rel003.htm#sthref2656" rel="nofollow"><code>OCIStmtGetBindInfo()</code></a> call to have it fill an array of bind variable names then iterate through it to find the position(s) for each named bind, either by comparing the bind name to the values in the bind variable names array (the values of which will be uppercased):</p> <pre><code>sb4 found = 0; text* bvns[100]; ub1 bvnls[100]; text* invs[100]; ub1 invls[100]; ub1 dupls[100]; OCIBind* bhnds[100]; OCIStmtGetBindInfo(stmthp, errhp, (ub4)100, (ub4)1, &amp;found, bvns, bvnls, invs, invls, dupls, bhnds); for (unsigned int col = 0; col &lt; found; col++) { printf("%p is bound to name: %s", bhnds[col], bvns[col]); } </code></pre> <p>One interesting thing to note about multiple placeholders in a statement is that it behaves differently if your statement is an anonymous block or not. That is: </p> <pre><code>insert into foo (bar, baz) values (:bar, :bar) </code></pre> <p>Will fill your <code>found</code> output variable with 2 (and the arrays with info for 2 binds), whereas:</p> <pre><code>begin insert into foo (bar, baz) values (:bar, :bar); end; </code></pre> <p>Will fill your <code>found</code> output variable with 1 (and the arrays with info for 1 bind). Nonetheless, a single call to <code>OCIBindByName()</code> will bind both in either case.</p>

    1. COI think you're right, there's no way to do it just within OCI. Thanks!

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
