从Perl脚本比较MySQL数据库中的日期

Question

我有一个带有MySQL查询的Perl脚本，如下所示

my $date         = strftime "%Y-%m-%d", localtime;

my $db_passwdcol = "password";
my $db_table     = "users";
my $db_usercol   = "username";
my $db_cond      = "expire_date";

my $sql_query    = "SELECT $db_passwdcol FROM $db_table WHERE $db_usercol = ?" . ($db_cond gt $date ? ");

我想要做的是使用SQL查询将当前值与过期日期进行比较。我尝试了许多变化，但无望。

提前致谢，

Answer 1

更改sql查询字符串，如下所示;

 $sql_query = "SELECT $db_passwdcol FROM $db_table WHERE $db_usercol = ? AND $db_cond > NOW()";

最佳，
