| dbCreateTable,DatabaseConnectorConnection-method {DatabaseConnector} | R Documentation |
Create a table in the database
Description
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.
Usage
## S4 method for signature '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
|
name |
The table name, passed on to
|
fields |
Either a character vector or a data frame. A named character vector: Names are column names, values are types.
Names are escaped with A data frame: field types are generated using
|
databaseSchema |
The name of the database schema. See details for platform-specific details. |
oracleTempSchema |
DEPRECATED: use |
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 |
temporary |
Should the table created as a temp table? |
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.
Value
dbCreateTable() returns TRUE, invisibly.
