CUBRID does not support default value constraints.

Error message

CUBRID does not support default value constraints.

What it means

yii\db\cubrid\Schema::loadTableDefaultValues() (framework/db/cubrid/Schema.php:241) is the loader behind Schema::getTableDefaultValues() and throws NotSupportedException unconditionally because Yii's CUBRID driver does not read default-value constraints from the catalog. Like loadTableChecks() above it, this fires from schema introspection rather than from DDL you wrote yourself.

Solutions

1. Skip default-value introspection when the driver is cubrid
2. Catch yii\db\NotSupportedException and degrade to an empty list
3. Read defaults from getTableSchema()->columns[x]->defaultValue instead, which the CUBRID driver does support

Example fix

// before
$defaults = $db->schema->getTableDefaultValues('product'); // throws on CUBRID

// after
try {
    $defaults = $db->schema->getTableDefaultValues('product');
} catch (\yii\db\NotSupportedException $e) {
    $defaults = []; // not supported by the CUBRID driver
}

$defaults = [];
if ($db->driverName !== 'cubrid') {
    $defaults = $db->schema->getTableDefaultValues($tableName);
} else {
    // column-level defaults are still available:
    foreach ($db->getTableSchema($tableName)->columns as $name => $column) {
        $defaults[$name] = $column->defaultValue;
    }
}

try {
    $defaults = $db->schema->getTableDefaultValues($tableName);
} catch (\yii\db\NotSupportedException $e) {
    $defaults = []; // fall back to TableSchema->columns[x]->defaultValue
}

When it happens

Trigger: $db->schema->getTableDefaultValues('product'); tooling iterating all constraint types (checks/uniques/defaults); schema diffing or ER-diagram generation against CUBRID.

Common situations: Cross-DBMS introspection utilities; model/code generators enumerating constraints; QA tooling that validates schema expectations on every supported driver.
