Objects made from Apex classes defined by the user.An enumeration is a typed list of values.A primitive-to-primitive map, sObject, or collection.A list (or array) of primitives, sObjects, user-defined objects, Apex classescreated objects or collections.A collection that includes the following items:.A sObject, such as an Account, Contact, or M圜ustomObject c, is either general or particular.Integer, Double, Long, Date, Datetime, String, ID, or Boolean are examples of primitives.We use these data types as it is required depending on the condition. Apex in Salesforce assigns a data type to all variables and expressions, such as sObject, primitive, or enum. redshift OPTIONS ( dbtable 'tbl_write', forward_spark_s3_credentials 'true', tempdir 's3n://path/for/temp/data' url 'jdbc:redshift://redshifthost:5439/database?user=username&password=pass' ) AS SELECT * FROM tabletosave - Using IAM Role based authentication instead of keys CREATE TABLE tbl USING com. redshift OPTIONS ( query 'select x, count(*) from table_in_redshift group by x', forward_spark_s3_credentials 'true', tempdir 's3://path/for/temp/data', url 'jdbc:redshift://redshifthost:5439/database?user=username&password=pass', ) - Writing to Redshift - Create a new table in redshift, throws an error if a table with the same name already exists CREATE TABLE tbl_write USING com. redshift OPTIONS ( dbtable 'tbl', forward_spark_s3_credentials 'true', tempdir 's3://path/for/temp/data', url 'jdbc:redshift://redshifthost:5439/database?user=username&password=pass', ) - Load Redshift query results in a Spark dataframe CREATE TABLE tbl USING com.
