| dbAppendTable,DatabaseConnectorConnection,character-method {DatabaseConnector} | R Documentation |
Insert rows into a table
Description
The dbAppendTable() method assumes that the table has been created
beforehand, e.g. with dbCreateTable().
The default implementation calls sqlAppendTableTemplate() and then
dbExecute() with the param argument. Backends compliant to
ANSI SQL 99 which use ? as a placeholder for prepared queries don't need
to override it. Backends with a different SQL syntax which use ?
as a placeholder for prepared queries can override sqlAppendTable().
Other backends (with different placeholders or with entirely different
ways to create tables) need to override the dbAppendTable() method.
Usage
## S4 method for signature 'DatabaseConnectorConnection,character'
dbAppendTable(
conn,
name,
value,
databaseSchema = NULL,
temporary = FALSE,
oracleTempSchema = NULL,
tempEmulationSchema = getOption("sqlRenderTempEmulationSchema"),
...,
row.names = NULL
)
Arguments
conn |
A DBIConnection object, as returned by
|
name |
The table name, passed on to
|
value |
A data frame of values. The column names must be consistent with those in the target table in the database. |
databaseSchema |
The name of the database schema. See details for platform-specific details. |
temporary |
Should the table created as a temp table? |
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 |
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
dbAppendTable() returns a
scalar
numeric.
