如何执行PreparedStatement的Sybase IQ中（选择OBJECT_ID（））？(H

我们有一个小的JDBC应用程序，会谈到Sybase IQ数据库，其作用：

String objectName = "SYS.SYSWEBSERVICE"; 
//The actual value of objectName does not matter.
//It could be any view object in the sys schema

PreparedStatement preparedStatement =
    connection.prepareStatement("SELECT OBJECT_ID(?)");
preparedStatement.setString(1, objectName);
preparedStatement.executeQuery();

我们收到此错误：

java.sql.SQLException: JZ0SA: Prepared Statement: Input parameter not set, index: 0.s

我看着http://infocenter.sybase.com/help/index.jsp?topic=/com.sybase.infocenter.dc39001.0700/html/prjdbc0700/CHDGJJIG.htm

JZ0SA: Prepared Statement: Input parameter not set, index: _____.
Action: Be sure that each input parameter has a value.

当我更改代码

setString(0, objectName)

我正进入（状态：

java.lang.ArrayIndexOutOfBoundsException: -1
    at com.sybase.jdbc4.jdbc.SybPreparedStatement.a(Unknown Source)
    at com.sybase.jdbc4.jdbc.SybPreparedStatement.a(Unknown Source)
    at com.sybase.jdbc4.jdbc.SybPreparedStatement.a(Unknown Source)
    at com.sybase.jdbc4.jdbc.SybPreparedStatement.setString(Unknown Source)

我们使用jconn-4.0.jar：

Manifest-Version: 1.0
Created-By: 1.6.0_03 (Sun Microsystems Inc.)
Main-Class: SybVersion

Name: com/sybase/jdbcx/
Implementation-Vendor: "Sybase, Inc."
Specification-Title: "jConnect for JDBC 4.0"
Implementation-Title: "com.sybase.jdbcx"
Implementation-Version: "Build (26502)"
Specification-Version: "7.0"
Specification-Vendor: "Sybase, Inc."

谁能告诉我什么，我做错了什么？谢谢。

尽管什么API文档可能会说，我觉得参数索引必须从零开始，也许这是你正在使用JDBC驱动程序中的错误。尝试用从零开始的索引。的SetString（0，....）;
