write.jdbc {SparkR}

R Documentation

+ +

Save the content of SparkDataFrame to an external database table via JDBC.

+ +

Description

+ +

Save the content of the SparkDataFrame to an external database table via JDBC. Additional JDBC +database connection properties can be set (...) +

+ + +

Usage

+ +

+## S4 method for signature 'SparkDataFrame,character,character'
+write.jdbc(x, url, tableName,
+  mode = "error", ...)
+
+write.jdbc(x, url, tableName, mode = "error", ...)
+

+ + +

Arguments

+ + + + + + + + + + + + +

`x`	+ a SparkDataFrame. +
`url`	+ JDBC database url of the form `jdbc:subprotocol:subname`. +
`tableName`	+ yhe name of the table in the external database. +
`mode`	+ one of 'append', 'overwrite', 'error', 'ignore' save mode (it is 'error' by default). +
`...`	+ additional JDBC database connection properties. +

+ + +

Details

+ +

Also, mode is used to specify the behavior of the save operation when +data already exists in the data source. There are four modes: +

+ +

append: Contents of this SparkDataFrame are expected to be appended to existing data. +
+
overwrite: Existing data is expected to be overwritten by the contents of this +SparkDataFrame. +
+
error: An exception is expected to be thrown. +
+
ignore: The save operation is expected to not save the contents of the SparkDataFrame +and to not change the existing data. +
+

+ + + +
