Here is my code: <?php require('../_DSN/DSN_M.php'); $cnnOra = odbc_connect($strarrDSN['dsn'], $strarrDSN['username'], $strarrDSN['pswd']); $res_slct = odbc_exec($cnnOra, " select * FROM person;") or die (odbc_errormsg()); odbc_result_all($res_sldr); $sqlupd = "UPDATE person SET person_ame='Steve Woz' WHERE pk

问题 This is related to my previous question. I'm trying, in Excel, to update external data connections to text files (used by several pivot tables) to point to the correct data sources so data can be refreshed when the Excel workbook and text files are copied to a different directory/computer. (It should act like the paths to the text files are relative.) The data sources are tab delimited text files with the headers in the first columns. I have code that can change the path in the ODBC

问题 I am having some issues connection to an oracle DB using MS Access. If I use SQL Developer to connect to the Oracle DB I see pretty much every table and view in the DB however when I connect using MS Access I only get a selected few. I tough it was because the user didn't have Select privileges on the tables I need so I requested the privilege and after a moth of waiting I finally got it but I still cant see the tables on the Access tool. This is what I see on SQL Developer vs MS access. I

问题 I'm connecting to a SAP HANA tenant database. As I understand it, there are two ways to do this: first, I can specify <server hostname>:<tenant db sql port> for the SERVERNODE connection property. Second, I can specify <server hostname>:<system db sql port> for SERVERNODE and also include the DATABASE connection property set to <tenant db name> . It's recommended to use the second method because it makes operations like moving tenant dbs (i.e. changing sql ports) easier (see "SAP HANA

问题 Daily, I currently have to: download 50 files, 40 are in .csv (comma separated values) format, and 10 in .txt. In each of the .csv files, there are 5 columns (call them B, A, D, C, E), and a differernt 5 columns in the .txt files (call them G, H, I, J, K). I then have to manually open in Excel and rearange the .csv columns into (A, B, C, D, E) for each of the 40 files. The .txt file are already in the required format. I then load these all into 15 teradata tables, using BTEQ on unix There are

问题 From R Studio's ODBC database documentation I can see a simple example of how to read a SQL table into an R data frame: data <- dbReadTable(con, "flights") Let me paste a graphic of the BGBUref table(?) I'm trying to read to an R data frame. This is from my connection pane in R studio. If I use the same syntax as above, where con is the output of my dbConnect(...) I get the following: df <- dbReadTable(con, "BGBURef") #> Error: <SQL> 'SELECT * FROM "BGBURef"' nanodbc/nanodbc.cpp:1587: 42S02:

问题 I'm using Python to read and write SAS datasets, using pyodbc and the SAS ODBC drivers. I can load the data perfectly well, but when I save the data, using something like: cursor.execute('insert into dataset.test VALUES (?)', u'testing') ... I get a pyodbc.Error: ('HY004', '[HY004] [Microsoft][ODBC Driver Manager] SQL data type out of range (0) (SQLBindParameter)') error. The problem seems to be the fact I'm passing a unicode string; what do I need to do to handle this? 回答1: Do you know what
