jconnect6 连接sybase iq 15 问题
各位老大，在mysql中下面的代码（？在= 左边的情况）可以运行，而在sybase中报错，有没有哪位兄弟遇到过啊。

Java code

Class.forName(driver);        Connection connection = DriverManager.getConnection(url,username,password);        PreparedStatement statement = connection.prepareStatement("select * from managedaccount where  ?=1");        statement.setString(1, "1");        statement.executeQuery();

错误如下：

Java code

Exception in thread "main" com.sybase.jdbc3.jdbc.SybSQLException: SQL Anywhere Error -143: Column '@p0' not found    at com.sybase.jdbc3.tds.Tds.processEed(Tds.java:3069)    at com.sybase.jdbc3.tds.Tds.nextResult(Tds.java:2373)    at com.sybase.jdbc3.jdbc.ResultGetter.nextResult(ResultGetter.java:69)    at com.sybase.jdbc3.jdbc.SybStatement.nextResult(SybStatement.java:220)    at com.sybase.jdbc3.jdbc.SybStatement.nextResult(SybStatement.java:203)    at com.sybase.jdbc3.jdbc.SybStatement.queryLoop(SybStatement.java:1705)    at com.sybase.jdbc3.jdbc.SybStatement.executeQuery(SybStatement.java:1690)    at com.sybase.jdbc3.jdbc.SybPreparedStatement.executeQuery(SybPreparedStatement.java:97)    at Test.main(Test.java:29)

[解决办法]
看一下sql写法是否正确...
[解决办法]
sybase好像不支持那样的语法
[解决办法]
select * from managedaccount where ?=1:
你用字符串累加生成SQL语句，再动态执行，不支持这种写法
