问题 I occasionally use iseries navigators "generate sql" to convert out DDS objects into sql code. Is there a way to automate this? or perhaps a green screen equivalent command? what I'm really after is a way to translate a keyed logical file into a set of sql indexes. 回答1: You want to use the Generate Data Definition Language (QSQGNDDL) API... http://www-01.ibm.com/support/knowledgecenter/ssw_ibm_i_71/apis/qsqgnddl.htm There's at least two published utilities that use this API. http://www

问题 We are generating our jpa access layers with MyEclipse. Afterwards we have the generated models and data layer access services. We ran into some problems for some fields with a defined precision. Entity: @Entity public class TestEntity{ @Column(name="DECTEST", scale = 3, precision = 13) BigDecimal decTest; } Now we create a bean and try to save it: TestEntity te = new TestEntity(); te.setDecTest(new BigDecimal(1.2)); TestEntityService.save(te); We get the following error: Caused by: com.ibm

问题 I'm still a bit of a noob, so pardon if this question is a bit obvious. I did search for an answer but either couldn't understand how the answers I found applied, or simply couldn't find an answer.

问题 Have a table of suppliers that have 'approval codes' (VNDAPP) and a table of contracts that have 'requirement codes' (COXA). Contracts can have any number of requirements and suppliers can have any number of approvals. VNDAPP: (vendor approvals table) VNUM (vendor number) REQMT (approval code) COXA: (contract requirements table) CONTR (contract number) REQMT (requirement) Need to find all suppliers that have approvals that, as a minimum, meet the requirements of a certain contract.

问题 I'm running the following query using PHP's db2_prepare and db2_execute (schema names have been changed to protect the innocent): WITH U AS ( SELECT * FROM FOO.USR WHERE USR_ID = ? ), UC AS ( SELECT UC.* FROM FOO.USR_CNTRCT UC JOIN U ON U.USR_ID = UC.USR_ID ) , LC AS ( SELECT DISTINCT CNTRCT_ID FROM FOO.CNTRCT_LOC CL JOIN FOO.USR_LOC UL ON UL.SLS_CTR_CD = CL.SLS_CTR_CD JOIN U ON U.USR_ID = UL.USR_ID WHERE CL.SLS_CTR_CD IN (?,?,?,?) ) SELECT C.*, COALESCE(P.PGM_NM, CAST('' AS CHAR(80) CCSID 37

问题 How can I seach for a special character like "→" (0x1A)? An example for my query is: select * from Data where Name like '%→%' I want to use instead of "→" something like 0x1A. I can't use any Java or C# Code.

My DB2 environment runs on AS400/iSeries and use EBCDIC instead of

问题 I am new to the repository pattern but am creating a repository to connect to two different database types that have the same data structure. Where and how should I handle the connection? Here are my requirements/constraints/project description I will be connecting to SQL Server 2005 and DB2 (on Iseries) I will be using the repository in a WPF application. Although I would like to use Entity Framework, I cannot. This is because IBM charges a rediculous $11,000 for a product called DB2 Connect
