我正在使用MS

SQL查询数据库，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’在我的语法中不存在…

我已经读到有人遇到了同样的问题，但是他们使用的是存储过程，而我没有使用某些东西，所以我看不出他的解决方案对我有用。（他的解决方案是在过程调用周围添加花括号{}。

无论如何，下面我已经粘贴了相关代码。真希望有人能帮助我，让我感到沮丧。

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！

回答：

top如果您传入变量，SQL Server要求您在参数周围加上括号：

SELECT TOP (?)
