阅读更多关于 Concatenate Multiple Row Values into 1 Row, with SQL for iSeries

问题 First, I need to thank Kent Milligan and his article at http://www.mcpressonline.com/sql/techtip-combining-multiple-row-values-into-a-single-row-with-sql-in-db2-for-i.html for getting me as far in this problem as I have. But now I need to expand on what he has done here. To avoid you having to go to his article, the problem he addressed was concatenating string data from multiple rows into a single row in the resulting table. For example: Table Cars: Make Model Ford Fusion Chevy Tahoe Honda

DB2 for IBM iSeries: IF EXISTS statement syntax

阅读更多关于 DB2 for IBM iSeries: IF EXISTS statement syntax

问题 I am familiar with Sybase which allows queries with format: IF EXISTS () THEN ... ELSE ... END IF (or very close). This a powerful statement that allows: "if exists, then update, else insert". I am writing queries for DB2 on IBM iSeries box. I have seen the CASE keyword, but I cannot make it work. I always receive the error: "Keyword CASE not expected." Sample: IF EXISTS ( SELECT * FROM MYTABLE WHERE KEY = xxx ) THEN UPDATE MYTABLE SET VALUE = zzz WHERE KEY = xxx ELSE INSERT INTO MYTABLE (KEY

Capturing onkeydown in Javascript

阅读更多关于 Capturing onkeydown in Javascript

I have a web front-end to an AS/400 CGI application which allows the use of some of the F1 - F24 keys (depending on the page) as well as page-up, page-down etc - these are passed to the underlying application which handles them appropriately. For instance, on a given page, a user could either press the F3 button or press the F3 key - both of them will set the (hidden) CmdKey variable to have a name of '_K03' and a value of 'F03'. The button handling is simple and has no problems. To handle users pressing an actual F-key on the keyboard, I have had an IE-compatible script for a long time which

new here! Situation: I'm working on a project which needs to communicate with an AS/400 server. My task is to basically handle the requests which will be sent to the AS/400 server. To do this, all the user input should be in EDCDIC bytes. Problem: I have managed to convert packed decimals to String with the code below, found on this forum : public class PackedDecimal { public static long parse(byte[] pdIn) throws Exception { // Convert packed decimal to long final int PlusSign = 0x0C; // Plus sign final int MinusSign = 0x0D; // Minus final int NoSign = 0x0F; // Unsigned final int DropHO = 0xFF

SQL query of multi-member file on AS400

阅读更多关于 SQL query of multi-member file on AS400

On AS400 in interactive SQL in a 5250 session, select * from myfile returns rows from one member only when myfile has more than one member. How can I get rows from a specific member? Important: in the end I'd like to do this over JDBC with jt400 so really I want a solution that'll work there. Thanks. You can create an alias using the create alias command: CREATE ALIAS myLibrary/myAlias FOR memberLibrary/memberFile(memberName) This will allow you to run sql against that member using the alias like you would any other file: SELECT * FROM myLibrary/myAlias Just remember that the alias will stick

C#: Convert COMP-3 Packed Decimal to Human-Readable Value

阅读更多关于 C#: Convert COMP-3 Packed Decimal to Human-Readable Value

问题 I have a series of ASCII flat files coming in from a mainframe to be processed by a C# application. A new feed has been introduced with a Packed Decimal (COMP-3) field, which needs to be converted to a numerical value. The files are being transferred via FTP, using ASCII transfer mode. I am concerned that the binary field may contain what will be interpreted as very-low ASCII codes or control characters instead of a value - Or worse, may be lost in the FTP process. What's more, the fields are
