INSERT INTO
Description
The INSERT INTO statement inserts new rows into a table. The inserted rows can be specified by value expressions or result from a query.
Syntax
INSERT INTO [ TABLE ] table_identifier [ partition_spec ] [ ( column_list ) ]
{ VALUES ( { value | NULL } [ , ... ] ) [ , ( ... ) ] | query }
Parameters
-
table_identifier
Specifies a table name, which may be optionally qualified with a database name.
Syntax:
[ database_name. ] table_name -
partition_spec
An optional parameter that specifies a comma-separated list of key and value pairs for partitions.
Syntax:
PARTITION ( partition_col_name = partition_col_val [ , ... ] ) -
column_list
An optional parameter that specifies a comma-separated list of columns belonging to the
table_identifiertable. Spark will reorder the columns of the input query to match the table schema according to the specified column list.Note:The current behaviour has some limitations:
- All specified columns should exist in the table and not be duplicated from each other. It includes all columns except the static partition columns.
- The size of the column list should be exactly the size of the data from
VALUESclause or query.
-
VALUES ( { value
|NULL } [ , … ] ) [ , ( … ) ]Specifies the values to be inserted. Either an explicitly specified value or a NULL can be inserted. A comma must be used to separate each value in the clause. More than one set of values can be specified to insert multiple rows.
-
query
A query that produces the rows to be inserted. It can be in one of following formats:
- a
SELECTstatement - a
TABLEstatement - a
FROMstatement
- a
