Create a table in the database

Source: R/DBI.R

The default dbCreateTable() method calls sqlCreateTable() and dbExecute(). Backends compliant to ANSI SQL 99 don't need to override it. Backends with a different SQL syntax can override sqlCreateTable(), backends with entirely different ways to create tables need to override this method.

# S4 method for DatabaseConnectorConnection
dbCreateTable(
  conn,
  name,
  fields,
  databaseSchema = NULL,
  oracleTempSchema = NULL,
  tempEmulationSchema = getOption("sqlRenderTempEmulationSchema"),
  ...,
  row.names = NULL,
  temporary = FALSE
)

Arguments

conn

A DBIConnection object, as returned by dbConnect().

name

The table name, passed on to dbQuoteIdentifier(). Options are:

  • a character string with the unquoted DBMS table name, e.g. "table_name",

  • a call to Id() with components to the fully qualified table name, e.g. Id(schema = "my_schema", table = "table_name")

  • a call to SQL() with the quoted and fully qualified table name given verbatim, e.g. SQL('"my_schema"."table_name"')

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().

databaseSchema

The name of the database schema. See details for platform-specific details.

oracleTempSchema

DEPRECATED: use tempEmulationSchema instead.

tempEmulationSchema

Some database platforms like Oracle and Impala do not truly support temp tables. To emulate temp tables, provide a schema with write privileges where temp tables can be created.

...

Other parameters passed on to methods.

row.names

Must be NULL.

temporary

Should the table created as a temp table?

Value

dbCreateTable() returns TRUE, invisibly.

Details

The databaseSchema argument is interpreted differently according to the different platforms: SQL Server and PDW: The databaseSchema schema should specify both the database and the schema, e.g. 'my_database.dbo'. Impala: the databaseSchema should specify the database. Oracle: The databaseSchema should specify the Oracle 'user'. All other : The databaseSchema should specify the schema.
