Odbc Result Methods

Implementations of pure virtual functions defined in the DBI package for OdbcResult objects.

Usage

# S4 method for class 'OdbcResult'
dbClearResult(res, ...)

# S4 method for class 'OdbcResult'
dbFetch(res, n = -1, ...)

# S4 method for class 'OdbcResult'
dbHasCompleted(res, ...)

# S4 method for class 'OdbcResult'
dbIsValid(dbObj, ...)

# S4 method for class 'OdbcResult'
dbGetStatement(res, ...)

# S4 method for class 'OdbcResult'
dbColumnInfo(res, ...)

# S4 method for class 'OdbcResult'
dbGetRowCount(res, ...)

# S4 method for class 'OdbcResult'
dbGetRowsAffected(res, ...)

# S4 method for class 'OdbcResult'
dbBind(res, params, ..., batch_rows = getOption("odbc.batch_rows", NA))

Arguments

res

An object inheriting from DBI::DBIResult.

...

Other arguments passed on to methods.

n

maximum number of records to retrieve per fetch. Use n = -1 or n = Inf to retrieve all pending records. Some implementations may recognize other special values.

dbObj

An object inheriting from DBIObject, i.e. DBIDriver, DBIConnection, or a DBIResult.

params

For dbBind(), a list of values, named or unnamed, or a data frame, with one element/column per query parameter. For dbBindArrow(), values as a nanoarrow stream, with one column per query parameter.

batch_rows

The number of rows to retrieve. Defaults to NA, which is set dynamically to the minimum of 1024 and the size of the input. Depending on the database, driver, dataset and free memory, setting this to a lower value may improve performance.
