Usage

MySQL(...) "TSconnect"(q, dbname, ...) "TSget"(serIDs, con,  TSrepresentation=options()$TSrepresentation, tf=NULL, start=tfstart(tf), end=tfend(tf), names=NULL,  TSdescription=FALSE, TSdoc=FALSE, TSlabel=FALSE, TSsource=TRUE, vintage=getOption("TSvintage"), panel=getOption("TSpanel"),   ...) "TSput"(x, serIDs, con, Table=NULL,  TSdescription.=TSdescription(x), TSdoc.=TSdoc(x), TSlabel.=TSlabel(x), TSsource.=TSsource(x),   vintage=getOption("TSvintage"), panel=getOption("TSpanel"),  ...)

"TSdescription"(x, con, ...) "TSdoc"(x, con, ...) "TSlabel"(x, con, ...) "TSsource"(x, con, ...) "TSvintages"(con)

Arguments

q

A character string indicating the query interface to use, or a database connection object.

dbname

The name of the database to which the connection should be established, omitted if q is a database connection object.

con

A database connection.

serIDs

identifiers for series to extract.

x

data series to put on the database, or a series identifier for TSdescription and TSdoc or, for print, a database connection as returned by TSconnect.

TSrepresentation

time series representation to use for the result.

names

Optional character vector to use for series names.

tf

Optional tframe to use for truncating data. (See tfwindow.)

start

Optional start date to use for truncating data. (See tfwindow.)

end

Optional end date to use for truncating data. (See tfwindow.)

TSdescription

TRUE or FALSE indicating whether description should be extracted

TSdescription.

Description to put on the database.

TSdoc

TRUE or FALSE indicating whether documentation should be extracted.

TSdoc.

Documentation to put on the database.

TSlabel

TRUE or FALSE indicating whether series label should be extracted.

TSlabel.

Short series label to put on the database.

TSsource

TRUE or FALSE indicating whether source indication should be extracted.

TSsource.

Source indication to put on the database.

Table

Character string indicating database table. (In TSput this is necessary if it cannot be determined automatically).

vintage

Vintage to be supplied (if supported by db).

panel

Panel to be supplied (if supported by db).

...

Arguments passed to other methods or to RMySQL::MySQL

Value

Details

These are MySQL methods for TSdbi. See the TSdbi for details and see the vignette distributed with package TSdata for more complete examples. Package TSsql is required for functions createTSdbTables() and removeTSdbTables(). Typically createTSdbTables() will only be done once, and the tables will not be removed. These steps are done in the example below.
