...0. In the database is a database with two schemas (public and X). With RODBC (1.1-4) , I can connect to the database and get the tables with sqlTables(db). I can query tables in the schema with sqlQuery("SELECT * FROM X.test"). However, I can't get the columns in table X.test with sqlColumns(db,"X.test") //it returns Error in sqlColumns(db, "X.test") : 'X.test': table not found on channel If I do sqlColumns(db, "test") it returns [1] TABLE_QUALIFIER TABLE_OWNER TABLE_NAME COLUMN_NAME DATA_TYPE [6] TYPE_NAME...

Greetings -- in order to write back to SQL databases, one needs to create a dataframe with values. I can get column names of an existing table with sqlColumns. Say I have a vector of values (if they're all the same type), or a list (if different). How do I create a dataframe with column names given by my sqlColumns? To make it concrete, how do we make a dataframe A B C 1 2 3 out of column.names <- LETTERS[1:3] values <- 1:3 ? Chee...

Is there a way to get a table in a certain schema? The Oracle database I am using has a table by the same name in two different schemas. This creates problems in sqlUpdate because to sqlUpdate there are duplicate columns. The following is part of the output of sqlColumns: sqlColumns(eids, "TEST_ARTCL_INST")[,1:4] TABLE_CAT TABLE_SCHEM TABLE_NAME COLUMN_NAME 1 EIDS TEST_ARTCL_INST CHANNEL_ID 2 EIDS TEST_ARTCL_INST ARTICLE_TEST_ID 3 EIDS TEST_ARTCL_INST CHANNEL_OLD_ID 4...

John, perhaps you have found now a way install RPgSQL for windows2000, or anybody other ? many thanks for advance christian [SNIP] I wonder whether anyone has succeeded in building either the RPgSQL or the Rdbi.PGSQL and Rdbi packages for Windows. If so, would you be willing to share either the binary package(s) or

All, I am new in R. I found sqlSave() doesn't work for our Oracle9i.

Any help with this would be much appreciated! Thanks in advance, Megan

I am using asterisk 1.6.1.6 and have been setting up a system to use a Postgresql database as the realtime DB via the ODBC route.

Instead of guessing which data types are being used, I simply query the database and grab the data types (this will work even if the database has columns but is empty), then use this information when populating.

El manual especifica esa opcion, pero no da ningun ejemplo de como usarla. *varTypes an optional named character vector giving the DBMSs datatypes to be used for* *some (or all) of the columns if a table is to be
