A is left joined to B on one integer column. For all records where joined column of table A contains a null value all fields of the record in resultset are empty. The resultset usually containes more than one record. The records are retrieved by odbc_result. This is observed only on SQL Server 2005 Express. Checked with PHP 4.4.2 and 4.4.1 I have the original Windows build of PHP 4.4.2 Reproduce code: --------------- Table A cint integer cstr char ... Table B cint integer cstr char ... ... A left join B on A.cint = B.cint ... Expected result: ---------------- If A.cint is null only B.cstr should be empty. Actual result: -------------- All selected fields A.cint, A.cstr, B.cint, B.cstr are empty when retrieving them with odbc_result. When A.cint cotains an integer where a record with A.cint = B.cint exists all data are retrieved. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=36421&edit=1
