Which AWS database service is best suited for non-relational databases? PL/pgSQL are only for grouping. Figure 1: Teradata to Amazon Redshift migration using AWS SCT agents. 1. This behavior stays the same in the context of stored procedures. Create a Redshift cluster. Limits and differences for stored Session2_redshift =# insert into tab1 values (1); Session1_redshift =# select * from tab2; If the result of the SELECT statements isn't important (that is, the atomicity of the operations in the transactions isn't important), move the SELECT statements outside of their transactions, as shown in the following examples: This restriction applies within the xact_id_undone : bigint : ID for the transaction that was undone.
