An SQL statement that contains quotes (i.e. ") instead of apostrophes (i.e. ') to delimit strings works fine in Access, however, in odbc_exec, it fails with
[Microsoft][ODBC Microsoft Access Driver] Too few parameters. Expected 6.
For example:
$q = "INSERT INTO TableA (Fld1, Fld2, Fld3) VALUES('A', 'B', 'C');"
works fine in both Access and ODBC, but
$q = 'INSERT INTO TableA (Fld1, Fld2, Fld3) VALUES("A", "B", "C");'
fails with the above error.
