How to set up ODBC 10.1b for Progress DB

阅读更多关于 How to set up ODBC 10.1b for Progress DB

问题 I'm trying to set up an ODBC client driver for Progress 10.1b. I was able to install the client software that is required, but there is apparently also an ODBC.reg script file that needs to be run to correctly set up the registry in order for me to use the ODBC drivers. Can anyone point me to where I would find this script? Or tell me the set of registry entries that would have to be made? 回答1: That's not a standard part of the install process. Are these the steps that you followed to get the

I don't have access to

问题 I get this error from Progress database when running the following query using ODBC: SELECT distinct Table.column, { fn CONVERT(SUBSTRING(Table.ProblematicColumn, 1, 60), SQL_VARCHAR)} as test FROM PUB.Table WHERE ( Table.id IN ( SELECT Table.id FROM PUB.Table ) ) I know it's possible to fix it using the DBTools. However, I run queries against multiple Progress databases of multiple clients, so it's not practical to do this every time. Also, for some reason, the ODBC client I'm using (PHP),

Static vs dynamic queries in OpenEdge

阅读更多关于 Static vs dynamic queries in OpenEdge

问题 Question is very common, let's see pros and cons of each in OpenEdge in terms of code readability, flexibility and performance off course. Static queries: + readability: convenient `buffer.field` notation + performance: higher (supposedly, need comments) -/+ "global scope" allows to handle all previously used buffers, but could lead to ambiguousness, so you'll have to clarify it with a table name (table.field instead of field) - flexibility: you cannot alternate predicate-expression much,

I'm trying to develop a program that will connect to a Progress Database (9.1E) using C# (Visual Studio 2010 Ultimate), but I first need to get a connection string to the Progress Database from the C# program.

I'm using ArchLinux and I am trying to install OpenEdge progress drivers so I can access it via PHP. I've installed the unixodbc package and the drivers, but when I test the connection via isql or PHP, I get the same error... # isql -3 SUBS2A [01000][unixODBC][Driver Manager]Can't open lib '/usr/dlc/odbc/lib/pgoe1023.so' : file not found [ISQL]ERROR: Could not SQLConnect The messed up thing is that "/usr/dlc/odbc/lib/pgoe1023.so" presently exists, I even symlinked it from "/usr/dlc".

Exclude rows based on other rows (SQL)

阅读更多关于 Exclude rows based on other rows (SQL)

Say I have a query like this: SELECT * FROM TABLE And it returns this: TABLE ID | DATA | VAL =============== 01 | ABCD | 1 01 | DEFG | 2 02 | FGHI | 3 02 | HIJK | 2 03 | JKLM | 3 03 | LMNO | 4 04 | NOPQ | 0 04 | PQRS | 1 Currently I have a query that attempts find only good values like this, but it's flawed because IDs that have bad VALs in other rows are included, which is not what I'd like. SELECT * FROM TABLE WHERE TABLE.VAL IN ("1","2","3") would return this (with LMNO and PQRS missing): TABLE ID | DATA | VAL =============== 01 | ABCD | 1 01 | DEFG | 2 02 | FGHI | 3 02 | HIJK | 2 03 | JKLM
