com.microsoft.sqlserver.jdbc.SQLServerException:'@ P0'附近的语法不正确

Question

我有一个SQL server 2008程序,它返回一个参数,我从java调用它.我的代码如下

存储过程代码是

Create PROCEDURE countInfected @infected int out
AS
Select @infected = COUNT(*) from userInfo
where userID NOT IN (Select userID from deletedInfo);

Java调用代码是

CallableStatement infected = null;
infected = con.prepareCall("call countInfected(?)");
infected.registerOutParameter(1, java.sql.Types.INTEGER);
infected.execute();
System.out.println("Infected"+ infected.getInt(1));

但是infected.execute(); 正在生成以下错误

com.microsoft.sqlserver.jdbc.SQLServerException:'@ P0'附近的语法不正确

请指导我哪里有问题

Answer 1

正如@GregHNZ提供的这个链接所暗示的那样,SQL Server需要一组围绕调用的花括号.

代码中的行如下所示:

infected = con.prepareCall("{ call countInfected(?) }");
