Bug #53353 [NEW]: Error retrieving data from MDB database: column is DOUBLE

From: Operating system: Windows 7 PHP version: Irrelevant Package: ODBC related Bug Type: Bug Bug description:Error retrieving data from MDB database: column is DOUBLE Description: ------------ Test environment: - Windows 7 32bit, PHP 5.2.9 and PHP 5.3.1., MS Access 2002 SP3 - ODBC 'DSN1': Microsoft Access Driver (*.mdb) 6.01.7600.16385 - ODBC 'DSN2': Microsoft Access Driver (*.mdb,*.adccdb) 14.00.4760.1000 - Test to access the database also performed with IDL (www.ittvis.com) In the access database I have a value -0.0864691123456789 (this is 19 characters long which is important) in a column defined as DOUBLE. When I connect to the database with 'DSN1' then I get an ASCII 0 back with PHP 5.2.9 and 5.3.1. When I connect to the database with 'DSN2' then I get an 'E-2' (the exponent of the floating point number) back with PHP 5.2.9 and 5.3.1. When I retrieve the data with IDL from 'DSN1' and 'DSN2' I get the correct numbers. When I cut the last character in the access database -0.086469112345678 so that the cell contains only 18 characters, the correct numbers are retrieved with PHP.
