labkey.updateRows: Update existing rows of data in a labkey database

Description

Send data from an R session to update existing rows of data in the database.

Usage

labkey.updateRows(baseUrl, folderPath,
    schemaName, queryName, toUpdate)

Arguments

baseUrl

a string specifying the baseUrlfor the labkey server

folderPath

a string specifying the folderPath

schemaName

a string specifying the schemaNamefor the query

queryName

a string specifying the queryName

toUpdate

a data frame containing the row(s) of data to be updated

Value

A list is returned with named categories of command, rowsAffected, rows, queryName, containerPath and schemaName. The schemaName, queryName and containerPath properties contain the same schema, query and folder path used in the request. The rowsAffected property indicates the number of rows affected by the API action. This will typically be the same number as passed in the request. The rows property contains a list of row objects corresponding to the rows updated.

Details

A single row or multiple rows of data can be updated. The toUpdate data frame should contain the rows of data to be updated and must be created with the stringsAsFactors option set to FALSE. The names of the data in the data frame must be the column names from the labkey database. To update a row/column to a value of NULL, use an empty string ("") in the data frame (regardless of the database column type).
