Question

我有一个SQL查询：

DECLARE @output varchar(100) exec map.GetGenreStatusName 'Genre', '2018-03-16', @output OUTPUT select @output;

它返回smth，如：

<anonymous>
 Completed

我需要从java代码中获取它。我的变体是：

final String statusCheck = "DECLARE @output varchar(100) exec map.GetGenreProtocolStatusName ?, ?, ? OUTPUT select @output;";
List<String> chekList = new ArrayList<>();
 try (CallableStatement statement = connection.prepareCall(statusCheck)) {
       statement.setString(1, packageName);
        statement.setDate(2, date);
        statement.registerOutParameter("output", 12);
        statement.execute();
        ResultSet checkStatusResult = (ResultSet) statement.getObject(0);
        chekList.add(checkStatusResult.getString(0));
    }

如何从select到我的列表中将此字符串“Completed”？我用“？”尝试了不同的变种设置和注册输入/输出参数，我尝试像查询一样执行它，但没有。

已将字符串更改为：

final String statusCheck = "exec map.GetGenreProtocolStatusName ?, ?, ?;";

代码：

final Connection connection = DriverManager.getConnection（dataSourceUrl，dbProperties）;

    List<TvScheduleInterval> scheduleIntervals = new ArrayList<>();
    List<String> checkList = new ArrayList<>();

    try (CallableStatement statement = connection.prepareCall(statusCheck)) {
        statement.setString(1, packageName);
        statement.setDate(2, date);
        statement.registerOutParameter(3,12);
        statement.execute();
        checkList.add(statement.getString(3));
    }

立即工作。

声明输出参数并将其选为查询结果，T-SQL，JAVA
