Compose query to create a simple table

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

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"))
#> Warning: Do not rely on the default value of the row.names argument for sqlCreateTable(), it will change in the future.
#> <SQL> CREATE TABLE "my-table" (
#>   "a" integer,
#>   "b" text
#> )
#> 
sqlCreateTable(ANSI(), "my-table", iris)
#> Warning: Do not rely on the default value of the row.names argument for sqlCreateTable(), it will change in the future.
#> <SQL> CREATE TABLE "my-table" (
#>   "Sepal.Length" DOUBLE,
#>   "Sepal.Width" DOUBLE,
#>   "Petal.Length" DOUBLE,
#>   "Petal.Width" DOUBLE,
#>   "Species" TEXT
#> )
#> 

# By default, character row names are converted to a row_names colum
sqlCreateTable(ANSI(), "mtcars", mtcars[, 1:5])
#> Warning: Do not rely on the default value of the row.names argument for sqlCreateTable(), it will change in the future.
#> <SQL> CREATE TABLE "mtcars" (
#>   "row_names" TEXT,
#>   "mpg" DOUBLE,
#>   "cyl" DOUBLE,
#>   "disp" DOUBLE,
#>   "hp" DOUBLE,
#>   "drat" DOUBLE
#> )
#> 
sqlCreateTable(ANSI(), "mtcars", mtcars[, 1:5], row.names = FALSE)
#> <SQL> CREATE TABLE "mtcars" (
#>   "mpg" DOUBLE,
#>   "cyl" DOUBLE,
#>   "disp" DOUBLE,
#>   "hp" DOUBLE,
#>   "drat" DOUBLE
