Firstly, althought you are only generating a small list, using a CTE to generate a sequential list performs terribly and is best avoided. However, only variables declared before the bound cursor was declared will be substituted into it. (Same as FORWARD ALL.) statements run, and then control passes to the next statement after END CASE. The cursor cannot be open already, and it must have been declared as an unbound cursor variable (that is, as a simple refcursor variable). The following example demonstrates the use of FETCH into a variables. types each time they are run from a PL/pgSQL stored procedure, use the EXECUTE The before or just after the select_expressions list. Based on your cluster type values differs. I see, according to console output you run query as separate statements. the STL_QUERY table or Redshift console. Cursors are available, but no variables, stored procedures, or user created functions. The Solution 1: From the documentation, @UniqueConstraint annotation is used inside the @Table annotation on the entity-class level. efficient way to return large row sets from stored procedures. After that, check if there is more row left to fetch. To specify a portal name, simply assign a string to the refcursor variable before opening it.
