Mssql schema parase throws warning in addForeignKeys

[danomatic]

a key in rows is not defined. this snippet should fix it:

    $stmt = $this->dbh->query("SELECT ccu1.TABLE_NAME, ccu1.COLUMN_NAME, ccu2.TABLE_NAME AS FK_TABLE_NAME, ccu2.COLUMN_NAME AS FK_COLUMN_NAME, ccu2.CONSTRAINT_NAME AS FK_NAME
                                FROM INFORMATION_SCHEMA.CONSTRAINT_COLUMN_USAGE ccu1 INNER JOIN
                                        INFORMATION_SCHEMA.TABLE_CONSTRAINTS tc1 ON tc1.CONSTRAINT_NAME = ccu1.CONSTRAINT_NAME AND
                                        CONSTRAINT_TYPE = 'Foreign Key' INNER JOIN
                                        INFORMATION_SCHEMA.REFERENTIAL_CONSTRAINTS rc1 ON rc1.CONSTRAINT_NAME = tc1.CONSTRAINT_NAME INNER JOIN
                                        INFORMATION_SCHEMA.CONSTRAINT_COLUMN_USAGE ccu2 ON ccu2.CONSTRAINT_NAME = rc1.UNIQUE_CONSTRAINT_NAME
                                WHERE (ccu1.table_name = '".$table->getName()."')");

    $foreignKeys = array(); // local store to avoid duplicates
    while ($row = $stmt->fetch(PDO::FETCH_ASSOC)) {

        $lcol = $row['COLUMN_NAME'];
        $ftbl = $row['FK_TABLE_NAME'];
        $fcol = $row['FK_COLUMN_NAME'];
        $name = $row['FK_NAME'];

When do you see a warning? How to reproduce? Which line is fixed with your snippet in whichfile?

The current source is below. The variable $name is not defined. My code selects an extra column, FK_NAME, and assigns the variable.

    while ($row = $stmt->fetch(PDO::FETCH_ASSOC)) {

        $lcol = $this->cleanDelimitedIdentifiers($row['COLUMN_NAME']);
        $ftbl = $this->cleanDelimitedIdentifiers($row['FK_TABLE_NAME']);
        $fcol = $this->cleanDelimitedIdentifiers($row['FK_COLUMN_NAME']);

        $foreignTable = $database->getTable($ftbl);
        $foreignColumn = $foreignTable->getColumn($fcol);
        $localColumn = $table->getColumn($lcol);

        if (!isset($foreignKeys[$name])) {
