MS SQL异常：'@ P0'附近的语法不正确

问题描述

我正在使用MS SQL查询数据库，出于某种原因我收到以下错误： com.microsoft.sqlserver.jdbc.SQLServerException：'@ P0'附近的语法不正确即使这个P0在我的语法中不在任何地方......

I'm querying a DB using MS SQL and for some reason I get the following error: com.microsoft.sqlserver.jdbc.SQLServerException: Incorrect syntax near '@P0' even though this 'P0' isn't anywhere in my syntax...

我读过某人有同样的问题，但他们使用了存储proc，我没有使用的东西，所以我看不出他的解决方案对我有用。 （他的解决方案是关于在程序调用周围添加大括号{}。

I've read that someone has had a same issue but they were using a stored proc, something which I am not using so I don't see how his solution will work for me. (His solution being asomething about adding braces {} around the procedure call.

无论如何，下面我已经粘贴了相关的代码。真的希望有人可以帮我这个，得到非常沮丧。

Anyways, below I have pasted the relevant code. Really hope someone can help me with this, getting quite frustrated.

PreparedStatement stmt = null;
Connection conn = null;    

String sqlQuery = "SELECT TOP ? \n"+
                              "z.bankAccountNo, \n"+
                              "z.statementNo, \n"+
                              "z.transactionDate, \n"+
                              "z.description, \n"+
                              "z.amount, \n"+
                              "z.guid \n"+
                              "FROM \n"+
                              "( \n"+
                              "select  \n"+
                              "ROW_NUMBER() OVER (ORDER BY x.transactionDate, x.statementNo) AS RowNumber, \n"+
                              "x.transactionDate, \n"+
                              "x.statementNo, \n"+
                              "x.description, \n"+
                              "x.amount, \n"+
                              "x.bankAccountNo, \n"+
                              "x.guid \n"+
                              "FROM \n"+
                              "( \n"+
                              "SELECT  \n"+
                              "a.bankAccountNo,  \n"+
                              "a.statementNo,  \n"+
                              "a.transactionDate, \n"+
                              "a.description,  \n"+
                              "a.amount,  \n"+
                              "a.guid  \n"+
                              "FROM BankTransactions as a  \n"+
                              "LEFT OUTER JOIN BankTransactionCategories as b  \n"+
                              "ON a.category = b.categoryCode  \n"+
                              "WHERE b.categoryCode is null \n"+
                              ") as x \n"+
                              ") as z \n"+
                              "WHERE (z.RowNumber >= ?)";

stmt = conn.prepareStatement(sqlQuery);
stmt.setInt(1, RowCountToDisplay);
stmt.setInt(2, StartIndex);
ResultSet rs = null;
try{
    rs = stmt.executeQuery();
} catch (Exception Error){
    System.out.println("Error: "+Error);
}

提前致谢！

推荐答案

如果传入变量，SQL Server要求您在 top 的参数周围放置括号：

SQL Server requires you to place parenthesis around the argument to top if you pass in a variable:

SELECT TOP (?)
