I think we do not necessarily need a mysql procedure.
Refer to the following code block
```
public void dropKey(Connection conn, String tableName, String key,
boolean isForeignKey)
{
String alter_sql_str;
if (isForeignKey) {
alter_sql_str = "ALTER TABLE " + tableName + " DROP FOREIGN KEY
" + key;
} else {
alter_sql_str = "ALTER TABLE " + tableName + " DROP KEY " + key;
}
try(PreparedStatement pstmt = conn.prepareStatement(alter_sql_str);)
{
pstmt.executeUpdate();
s_logger.debug("Key " + key + " is dropped successfully from the
table " + tableName);
} catch (SQLException e) {
s_logger.debug("Ignored SQL Exception when trying to drop " +
(isForeignKey ? "foreign " : "") + "key " + key + " on table " + tableName + "
exception: " + e.getMessage());
}
}
```
