sqlCreateTable

Compose query to create a simple table

Description

Exposes an interface to simple CREATE TABLE commands. The default method is ANSI SQL 99 compliant. This method is mostly useful for backend implementers.

Usage

sqlCreateTable(con, table, fields, row.names = NA, temporary = FALSE, ...)

Arguments

`con`	A database connection.
`table`	Name of the table. Escaped with `dbQuoteIdentifier()`.
`fields`	Either a character vector or a data frame. A named character vector: Names are column names, values are types. Names are escaped with `dbQuoteIdentifier()`. Field types are unescaped. A data frame: field types are generated using `dbDataType()`.
`row.names`	Either `TRUE`, `FALSE`, `NA` or a string. If `TRUE`, always translate row names to a column called "row_names". If `FALSE`, never translate row names. If `NA`, translate rownames only if they're a character vector. A string is equivalent to `TRUE`, but allows you to override the default name. For backward compatibility, `NULL` is equivalent to `FALSE`.
`temporary`	If `TRUE`, will generate a temporary table statement.
`...`	Other arguments used by individual methods.

Details

The row.names argument must be passed explicitly in order to avoid a compatibility warning. The default will be changed in a later release.

Examples

sqlCreateTable(ANSI(), "my-table", c(a = "integer", b = "text"))
sqlCreateTable(ANSI(), "my-table", iris)

# By default, character row names are converted to a row_names colum
sqlCreateTable(ANSI(), "mtcars", mtcars[, 1:5])
sqlCreateTable(ANSI(), "mtcars", mtcars[, 1:5], row.names = FALSE)
