Php ORA-01036：非法变量名称/编号-oci\u按\u名称绑定\u

我已经用“select*from person”测试过了，效果不错。

我想得到一份名字以“a”开头的人的名单。这可能吗？

尝试将查询更新为：

$letter= "A";
$statement = oci_parse($connection, "select * from person where firstname like ':letter%'");
oci_bind_by_name($statement, ':letter', $letter);

oci_parse($connection, "select * from person where firstname like :letter || '%'");
