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，但由于某种原因，我收到以下错误:com.microsoft.sqlserver.jdbc.SQLServerException: Incorrect syntax near '@P0' 即使此 'P0' 不在我的语法中...

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...

我读到有人遇到了同样的问题，但他们使用的是存储过程，我没有使用它，所以我不知道他的解决方案对我有用.(他的解决方案是在过程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代码.真的希望有人能帮我解决这个问题，我很沮丧.

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 ? 
"+
                              "z.bankAccountNo, 
"+
                              "z.statementNo,

                              "z.transactionDate,

                              "z.description,

                              "z.amount,

                              "select

                              "ROW_NUMBER() OVER (ORDER BY x.transactionDate, x.statementNo) AS RowNumber,

                              "x.transactionDate,

                              "x.statementNo,

                              "a.statementNo,

                              "a.transactionDate,

                              "a.description,

                              "FROM BankTransactions as a

                              "LEFT OUTER JOIN BankTransactionCategories as b

                              "ON a.category = b.categoryCode

                              "WHERE b.categoryCode is null

                              ") as x

                              ") as z

                              "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

SQL Server 要求你在 top 的参数周围加上括号，如果你传入一个变量:

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

SELECT TOP (?)
