sqlCopy(channel, query, destination, destchannel = channel,
        verbose = FALSE, errors = TRUE, ...)

sqlCopyTable(channel, srctable, desttable, destchannel = channel,
             verbose = FALSE, errors = TRUE)

Arguments

channel, destchannel

connection handle as returned by odbcConnect.

query

any valid SQL statement

destination, srctable, desttable

character: a database table name accessible from the connected DSN.

verbose

Display statements as they are sent to the server?

errors

if TRUE halt and display error, else return -1.

...

additional arguments to be passed to sqlSave.

Details

sqlCopy as is like sqlQuery, but saves the output of query in table destination on channel destchannel.

sqlCopyTable copies the structure of srctable to desttable on DSN destchannel. This is within the limitations of the ODBC lowest common denominator. More precise control is possible via sqlQuery.

Value

See sqlGetResults.
