edbLog: Write an operation "log" (used when modifying the database)
In easydb: Generic S3 Classes for Simple Database Interfaces

Description Usage Arguments Author(s) See Also

Write an operation "log" (to be used when modifying the

database). An operation log consists in information about (a) the function

used, (b) the table modified, (c) the operation date, (d) R version, (e)

easydb version, (f) the option useds ('mode' and 'getKey' if used with

edbWrite()). This is not version control, and this is not comprehensive

operation log.

edbLog(edb, tableName = as.character(NA), fun = as.character(NA), 


    date = date(), R.version = R.version.string, nodename = Sys.info()[["nodename"]], 


    edbVersion = NULL, mode = as.character(NA), getKey = as.character(NA), 


    logRandId = rnorm(1), logMsg = as.character(NA), 


    logTableName = "edbLog", logCreateTableIfNotExist = TRUE)

`edb`	An object of class 'edb', such as returned by `edb`. Database in which the log has to be written.
`tableName`	Single character string. The name of the table that was modified. Not to be confused with 'logTableName'.
`fun`	Single character string. The name of the function that did the modification.
`date`	Single character string. The date and time of the operation.
`R.version`	Single character string. R version
`nodename`	Single character string. Name of the computer (node).
`edbVersion`	Single character string. Version of easydb. If NULL, the version is fetched using 'installed.packages()'.
`mode`	Single character string. Value of the argument 'mode', if fun is edbWrite().
`getKey`	Single character string. Value of the argument 'getKey', if fun is edbWrite().
`logRandId`	Single numerical. Some number, hopefully unique, that can be used to identify the log record, as a complement to the log date.
`logMsg`	Single character string. Aditional log message to be written in the log table (same record as the rest).
`logTableName`	Single character string. Name of the log table. If that table does not exist, it will be created.
`logCreateTableIfNotExist`	Single logical. If TRUE (the default), then the table is created if it does not exist yet. Please notice that this option is not multi-thread safe.
