When getting an associative array from a MSSQL database: with mssql_fetch_array(), the keys of the array can be no longer than 30 characters.

I have a field 'last_modification_user_login_id' (31 characters) in a table 'document', but after selecting all fields from that table, I can't access that field. A var_dump however on the array shows a key 'last_modification_user_login_i', which is 30 characters. It has the right value.

This is not a problem with:
- Databases: the same code works with MySQL and PostgreSQL on the 'same' database.
- Arrays: keys can be longer than 30 characters

So it has to be a 'mssql_fetch_array' bug!

Vincent

I am using the latest release of PHP 5.0 build 2195, release date Apr 25 2004 12:10:13.  I am also experiencing this problem.

The MSSQL library provided by Microsoft canonly handle name, table and column names of 30 characters or less. This is not possible to fix in the php extension, and Microsoft has not updated the library since the releaseof SQL server 6.x.
