Status: Feedback
Bug Type: MSSQL related
Operating System: Win 2000 Server
PHP Version: 4.3.5
New Comment:
mssql_query() does not do anything to the SQL statement, other than
passing it on to the SQL server (once). There is no code to resubmit
the same statement. The SQL statement can be a batch of inserts and or
other commands, and mssql_query() will return false if one statement
fails to execute on the server. A true value is returned if everything
was executed with success but no data sets were returned (INSERT,
UPDATE and DELETE statements). If a single statement returns a
recordset mssql_query() will return a reource handle for the data.
I think this is a bug in either your PHP code or in the SQL statements
(batches) you are sending to the server. Can you please provide some
more info woth some code that reproduces the error.

Huh? How can this be PHP bug?

Description:
------------
Depending of database and/or network charge, a single INSERT may be
executed more than one time by mssql_query(), even if the first INSERT
was executed successfully. The return code of mssql_query will be set
to the last executed INSERT.
In my case, a unique index prevented the subsequent INSERT's. This
caused a lot of confusion, because the first INSERT was completed
successful and mssql_query("INSERT INTO ...", $con) delivered "false"
nevertheless.
Problably, a longer delay time will be misinterpreted as a database
lock, and mssql_query tries to encounter this by repetitions of the
same INSERT.
Couldn't find any workaround for this.
I recognized this bug in PHP versions 4.3.2 - 4.3.5.
Expected result:
----------------
A succesful INSERT may not be repeated.
