 ==== Auto-Increment Column ====
 [[v5:dictionary:column_attributes#AUTO or AUTOINCREMENT|Auto-increment]] support for Oracle databases is implemented by creating an on-insert trigger that retrieves a sequence number from a sequence //**SEQ_ + table name **//. This is done by default.
+If you have long table names then the generated trigger name can exceed the maximum allowed length. To prevent this, use the class variable ''useCompactAutoIncrements''. This will change the trigger name to a generated CRC value of the name.
+=== Example using the table name "customer_delivery_address" ===
+By default, the trigger name would be SEQ_CUSTOMER_DELIVERY_ADDRESS which exceeds the 16 character name for sequences. By setting ''$db->useCompactAutoIncrements=true'', the sequence name is changed to ''SEQ_401703491''
+=== Accessing the trigger in your code ===
+<code php>
+$db->useCompactAutoIncrements=true;
+$tab = 'customer_delivery_address';
+$tab = sprintf('SEQ_%u',crc32(strtolower($tab)));
+print $tab; //prints SEQ_401703491

 A second difference to this driver is that it does not create a sequence to emulate auto-increment fields. You must provide the functionality yourself if you need it.

 This driver provides an undocumented enhancement to the oci8 driver. The differences in the driver relate solely to the use of cursors in stored procedures. This may be related to information in the function [[v5:database:oracle:executecursor|executeCursor]]  and the [[v5:userguide:oracle_tutorial|Oracle Tutorial]]. If you have the appropriate expertise and the time to investigate and explain these drivers, let us know.
