问题 I try to install informix on node.js via follow from "https://npmjs.org/package/nodejs-db-informix", but it's not success. I don't understand about Pre-req (Setup and configure Informix).

问题 I'm having multiple windows throughout my 4gl program where I have to position to the center of the screen. For example: OPEN WINDOW w_yesno AT 10, 10 WITH 4 ROWS, 56 COLUMNS ATTRIBUTE (BORDER, MESSAGE LINE FIRST+1, PROMPT LINE FIRST+2) Is there any keyword I can use to automatically open it in the center? Something like: OPEN WINDOW w_yesno AT CENTER 回答1: No, there isn't a keyword solution to centring windows. You can use variables for the positions and do the calculation, or you can do the

问题 I have a SQL query which was initially this- DELETE FROM table_1 WHERE column_1 IN ( SELECT column_1 FROM table_2 WHERE column_3 < CURRENT - INTERVAL(N) MONTH TO MONTH) Now my advisory has told to use Financial Close Year instead of CURRENT like: DELETE FROM table_1 WHERE column_1 IN ( SELECT column_1 FROM table_2 WHERE column_3 < FINANCIAL YEAR CLOSE - INTERVAL(N) MONTH TO MONTH) FINANCIAL YEAR CLOSE being March End. I have no idea as to how I should incorporate the changes. 回答1: Since

问题 Not really sure where to go with this one. I have a PHP script that invokes a PERL script that connects to an Informix database. This setup works just fine when I run the script to the Windows cmd prompt, but when I attempt to run it through cron in cygwin it fails on [Informix][Informix ODBC Driver]Unable to load translation shared library (DLL). (SQL-IM009) I have tried adding the Informix bin directory (/cygdrive/c/Program\ Files\ (x86)/IBM/Informix/Client-SDK/bin) to the PATH variable in

问题 I have a friend who has a management application, and he would like to import some of his data in Excel. The thing is I have no idea about how to read this type of files, In his application directory he has a folder named app.dbs. Inside there are *.idx and *.dat files. What would be the easiest way to read this files? Maybe ODBC connector, or installing some version of Informix DB?? 回答1: That sounds like C-ISAM files, or an Informix-SE (Standard Engine) install. You most certainly can't read

问题 I ask about alternative or similar query in informix to perform the following: INSERT INTO days (depcode,studycode,batchnum) values (1,2,3);SELECT SCOPE_IDENTITY(); I want a query to return the SCOPE_IDENTITY() during insertion statement 回答1: I know that in t-sql you have the OUTPUT statement? Where [KEY] is the column name of your primary key and @OUT_KEY is a variable you need to declare INSERT INTO days ( depcode, studycode, batchnum ) OUTPUT INSERTED.[KEY] INTO @OUT_KEY VALUES ( 1,2,3 )

问题 I have this Informix SQL statement which takes ages to run. Does anybody see any way to optimize it so it wouldn't take so long? SELECT * FROM OriginalTable WHERE type = 'S' AND flag <> 'S' INTO TEMP TempTableA; SELECT * FROM OriginalTable WHERE type = 'Z' AND flag <> 'S' INTO TEMP TempTableB; UPDATE OriginalTable SET flag = 'D' WHERE Serialnumber in ( select Serialnumber from TempTableA WHERE NOT EXISTS(SELECT * FROM TempTableB WHERE TempTableB.Col1 = TempTableA.Col1 AND TempTableB.Col2 =

问题 I wrote a function, StoogeFunk , that uses FOREACH against systables and syscolumns , to concatenate in a string the list of fields in a table (the name of which is passed as a function parameter). I surround with CAST/VARCHAR(30) the date fields, for reasons I dare not explain. So, I come to a point where I have in a string, SelectString , the equivalent of: SELECT Name, CAST(DOB AS VARCHAR(30)) AS DOB, ShoeSize FROM Stooges My function simply returns that LVARCHAR string (and it is a long

问题 I need to push data from Informix to my .NET server in real time, just like we can do it automatically as soon as there is a change in the database with SignalR and MS SQL Server. Can this be done? Informix doesn't seem to have inbuilt functionality that would allow .NET server to know whenever there is a new record in the database. I have not been able to find a solution to this even after hours and hours of searching with Google. 回答1: Since Informix 11.70, Informix has supported a Change
