JDBC调用SQL Server存储�q�程

在说明之�?先做一下准备工�?下面的说明主要针对SQL Server数据�?另外要保证jtds驱动�E�序已经��试通过.

调用带有输入和输出参数的存储�q�程

假设已经存在一个存储过�E�user_registry_stat,其代码如�?

                CREATE PROCEDURE user_registry_stat(@stylebook int,@result int output )AS
                    BEGIN
                    /*不返回计�?/
                    SET NOCOUNT ON

                    DECLARE @total_amount int
                    SET @total_amount = (SELECT count(id) as amount from CP_USER)

                    IF(@total_amount>@stylebook)
                    BEGIN
                          @result = 1
                    END
                    ELSE
                    BEGIN
                          @result =2
                    END

               JAVA执行代码如下:
               public static void executeStoredProcedure(Connection con) {
                     try {
                           CallableStatement cstmt = con.prepareCall("{call user_registry_s(?,?)}");
                            cstmt.seInt(1, 50);
                           cstmt.execute();
                           System.out.println("RETURN STATUS: " + cstmt.getInt(2));
                           cstmt.close();
                      }catch (Exception e) {
                           e.printStackTrace();
                     }
                  }
2.   调用带有�q�回状态的存储�q�程
            假设已经存在一个存储过�E�user_registry_stat,其代码如�?
                  CREATE PROCEDURE user_registry_stat(@stylebook int)AS
                    BEGIN
                    /*不返回计�?/
                    SET NOCOUNT ON

                    DECLARE @total_amount int
                    SET @total_amount = (SELECT count(id) as amount from CP_USER)

                    IF(@total_amount>@stylebook)
                        return 1
                    ELSE
                        return 2

            java执行代码如下:
            public static void executeStoredProcedure(Connection con) {
               try {
                  CallableStatement cstmt = con.prepareCall("{? = call user_registry_stat(?)}");
                  cstmt.registerOutParameter(1, java.sql.Types.INTEGER);
                  cstmt.seInt(2, 50);
                  cstmt.execute();
                  System.out.println("RETURN STATUS: " + cstmt.getInt(1));

                  cstmt.close();
            }catch (Exception e) {
               e.printStackTrace();
            }
         }
