我们有一个小型的jdbc应用程序与sybase iq数据库进行对话,该数据库执行:
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
JZ0SA: Prepared Statement: Input parameter not set, index: _____.
Action: Be sure that each input parameter has a value.
当我更改代码时
setString(0, objectName)
我得到了:
java.lang.ArrayIndexOutOfBoundsException: -1

at com.sybase.jdbc4.jdbc.SybPreparedStatement.setString(Unknown Source)
我们正在使用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."
有人能告诉我我做错了什么吗?谢谢。

尽管API文档可能会说,我认为参数索引必须从零开始,这可能是您正在使用的JDBC驱动程序中的错误。尝试使用从零开始的索引。了setString(0,....);
