If you use an argument, make sure its the CONNECTION_ID and not the RESULT_ID.
Testing the result can return a null string or sometimes a garbage string.
# -- Example code --
$rs = odbc_exec($dbc, $sql);
#this is wrong but won't error out until
#you demo the page for a client!
if (odbc_error($rs)) die(...);
#these work
if (odbc_error()) die(...);
if (odbc_error($dbc)) die(...);
Using IBM DB2 V7.1 and MS SQL Server 7 ODBC database connections.Print the result of odbc_error() or odbc_errormsg() after each call to an odbc_ function that gives no error and, sooner or later, you'll get garbage instead of a blank string!
On persistent connections, a failed T-SQL will allow odbc_error and odbc_errormsg to return the error, but a subsequent successful T-SQL will not clear the error. Is it a bug?
