将java整数数组作为参数传递给postgres过程

定义java整数数组如下：

Integer[] details = {5097, 5098, 5099, 5100, 5101, 5102, 5121, 5122, 5123, 5124, 5125, 5126, 5127, 5128, 5129, 5130};

connection = (Connection) DriverManager.getConnection(MySQLURL,"postgres","admin");
Array dArray = connection.createArrayOf("INT", details);

String simpleProc = "{ call SMS.P_DELETE_DATA("+dArray+") }";
        CallableStatement cs = connection.prepareCall(simpleProc);
        cs.execute();

CREATE FUNCTION SMS.P_DELETE_WORKPLAN_FOR_LESSON(P_LESSONS INT[]) 
 RETURNS VOID AS $$

然后使用连接对象将java数组转换为postgres类型数组，如下所示

Integer[] details = {5097, 5098, 5099, 5100, 5101, 5102, 5121, 5122, 5123, 5124, 5125, 5126, 5127, 5128, 5129, 5130};

connection = (Connection) DriverManager.getConnection(MySQLURL,"postgres","admin");
Array dArray = connection.createArrayOf("INT", details);

String simpleProc = "{ call SMS.P_DELETE_DATA("+dArray+") }";
        CallableStatement cs = connection.prepareCall(simpleProc);
        cs.execute();

CREATE FUNCTION SMS.P_DELETE_WORKPLAN_FOR_LESSON(P_LESSONS INT[]) 
 RETURNS VOID AS $$

之后，将dArray作为参数传递给postgres程序，如下所示

Integer[] details = {5097, 5098, 5099, 5100, 5101, 5102, 5121, 5122, 5123, 5124, 5125, 5126, 5127, 5128, 5129, 5130};

connection = (Connection) DriverManager.getConnection(MySQLURL,"postgres","admin");
Array dArray = connection.createArrayOf("INT", details);

String simpleProc = "{ call SMS.P_DELETE_DATA("+dArray+") }";
        CallableStatement cs = connection.prepareCall(simpleProc);
        cs.execute();

CREATE FUNCTION SMS.P_DELETE_WORKPLAN_FOR_LESSON(P_LESSONS INT[]) 
 RETURNS VOID AS $$

我写了博士后程序签名如下

Integer[] details = {5097, 5098, 5099, 5100, 5101, 5102, 5121, 5122, 5123, 5124, 5125, 5126, 5127, 5128, 5129, 5130};

connection = (Connection) DriverManager.getConnection(MySQLURL,"postgres","admin");
Array dArray = connection.createArrayOf("INT", details);

String simpleProc = "{ call SMS.P_DELETE_DATA("+dArray+") }";
        CallableStatement cs = connection.prepareCall(simpleProc);
        cs.execute();

CREATE FUNCTION SMS.P_DELETE_WORKPLAN_FOR_LESSON(P_LESSONS INT[]) 
 RETURNS VOID AS $$

但是当我运行java代码时，它抛出格式错误的过程/函数调用……

有人建议我解决这个问题

提前感谢。

Hełm，您应该使用方法而不是Sql字符串为Sql语句设置参数。 试着这样做：

        connection = (Connection) DriverManager.getConnection(MySQLURL,"postgres","admin");
        Array dArray = connection.createArrayOf("INT", details);
        String simpleProc = "{ call SMS.P_DELETE_DATA(?) }";
        CallableStatement cs = connection.prepareCall(simpleProc);
        cs.setArray(1, dArray);
        cs.execute();
        cs.close();
