Stored procedures 如何将错误记录作为DB2存储过程标准输出的一部分输出
有时，当我们执行错误记录时，我们会得到错误数据和下面的存储过程错误，错误代码如下所示 “sql>调用REFLOADER.SP_ALL_ES_CODE（） [2018-11-20 10:14:01][22004][87]在不允许使用空值的上下文中指定了空值。.SQLCODE=-87，SQLSTATE=22004，DRIVER=4.23.42.“ 因此，我想**将错误代码与下面脚本中失败的错误值/记录集一起分离出来。您能否帮助我了解代码，在哪里以及如何获得错误记录输出。** 在这里输入代码 创建或替换过程SCHEMA1.SP_ALL_代码（） 动态结果集1 P1：开始Stored procedures 如何将错误记录作为DB2存储过程标准输出的一部分输出,stored-procedures,error-handling,db2-luw,Stored Procedures,Error Handling,Db2 Luw,有时，当我们执行错误记录时，我们会得到错误数据和下面的存储过程错误，错误代码如下所示 “sql>调用REFLOADER.SP_ALL_ES_CODE（） [2018-11-20 10:14:01][22004][87]在不允许使用空值的上下文中指定了空值。.SQLCODE=-87，SQLSTATE=22004，DRIVER=4.23.42.“ 因此，我想**将错误代码与下面脚本中失败的错误值/记录集一起分离出来。您能否帮助我了解代码，在哪里以及如何获得错误记录输出。** 在这里输入代码 创建或替
