DBD::SQLite::db prepare failed: unrecognized token:

问题：

perl INSERT 数据库操作过程中出现： DBD::SQLite::db prepare failed: unrecognized token:

修改前：

$orderInfo = "{orderInfo: $data}";
$stmls = "INSERT INTO strokeOrder(Name,OrderInfo) values('$nameInfo[1]','$orderInfo')";
$sth = $dbh->prepare($stmls);
$rv = $sth->execute() or die $DBI::errstr;

$orderInfo 包含有 31d0 之类的字符

修改后：

$orderInfo = "{orderInfo: $data}";
$stmls = "INSERT INTO strokeOrder(Name,OrderInfo) values(?,?)";
$sth = $dbh->prepare($stmls);
$rv = $sth->execute($nameInfo[1],$orderInfo) or die $DBI::errstr;
