Pass Array as parameter in DB2 Stored Procedure

自作多情 提交于 2019-12-07 22:51:27
I am trying to create a stored procedure which takes an array as a parameter and in the WHILE loop iterates through this array and adds the chars into a table. For example if I had an array of ['a','b','c'] I would want to pass this into my stored procedure and the characters 'a' , 'b' and 'c' to be placed into a table. My SP creates successfully, but I am having issues when I try to call my procedure. Can anybody point me towards how to pass in an array? My procedure is as follows.... DROP PROCEDURE DB.LWRH_DYNAMIC_SP@ create type stringArray as VARCHAR(100) array[100]@ CREATE PROCEDURE DB

问题 I am trying to connect to an IBM DB2 9 database on a Linux server from my Java application. I am using db2jcc.jar (DB2 Universal JDBC Driver). Establishing a connection is taking a ridiculous amount of time. What could be wrong? I know there are a lot of factors that could cause this, but I want to get down to the root cause. 回答1: First off I would try to up the log level on the driver to debug or even trace. This might give you an easy way of seeing where it is hanging in it's attempt to

只谈情不闲聊 提交于 2019-12-07 18:52:13
问题 Is there a function/package available in DB2 9.5 to calculate MD5 hash? Something similar to Oracle's DBMS_OBFUSCATION_TOOLKIT.MD5 ? 回答1: There is no built-in function to do this, but you can certainly create your own User Defined Function (UDF). This Developerworks article contains an implementation: http://www.ibm.com/developerworks/data/library/techarticle/dm-0407tessarek/#UDFs 回答2: There is GET_HASH_VALUE function in DB2 9.7 part of DBMS_UTILITY system module.

说实话,ORACLE把国内的程序员惯坏了,代码中的SQL充斥着大量ORACLE特性,几乎没人知道ANSI的标准SQL是什么样子,导致程序脱离了ORACLE根本无法运行,还好随着hibernate的流行,情况有了很大改观 DB2 作为众多国际大客户的选择(据说世界500强80%用 DB2 ,前100强更是全部采用 DB2 ),在国内真的很不流行,属于小众数据库,但是没办法,现在的项目要用 DB2 ,所以不得不面对熟悉ORACLE的开发同事们写出的“ORACLE版代码”,众多的兼容性问题搞得很是头大,遂整理了一份经常遇到的兼容性问题列表供大家参考,貌似最近问题少了些,但愿这个势头能继续下去 1、数据类型转换函数 整型转 字符型 字符串 转整形 字符串 转浮点型 浮点型 转字符串 字符串 转日期 字符串 转时间戳 日期 转字符串 ORA to_char(1) to_number ('1') to_number ('1.1') to_char (1.1) to_date ('2007-04-26','yyyy-mm-dd') to_date ('2007-04-26 08:08:08','YYYY-MM-DD HH24:MI:SS') to_char ( to_date ('2007-04-29','yyyy-mm-dd'),'yyyy-mm-dd') DB2 char(1) int('1

SQL query: how to translate IN() into a JOIN?

岁酱吖の 提交于 2019-12-07 14:31:41
问题 I have a lot of SQL queries like this: SELECT o.Id, o.attrib1, o.attrib2 FROM table1 o WHERE o.Id IN ( SELECT DISTINCT Id FROM table1 , table2 , table3 WHERE ... ) These queries have to run on different database engines (MySql, Oracle, DB2, MS-Sql, Hypersonic), so I can only use common SQL syntax. Here I read, that with MySql the IN statement isn't optimized and it's really slow, so I want to switch this into a JOIN . I tried: SELECT o.Id, o.attrib1, o.attrib2 FROM table1 o, table2, table3

问题 For a DB2 on z/OS Materialized Query Table, how can you retrieve the last refresh time? The documentation states that one of the actions that DB2 takes during a REFRESH is to populate the catalog with a refresh timestamp.

I was looking for this in order to compare the time stamp with another resource to see if it has changed since the last
