I know how to run a simple "select * from table" in java postgres jdbc connector.
But how do we run two or more statements, where statement2 depends on statement1 using java/JDBC-Postgres?
Example #1:
SET search_path TO a,b,c;
Select * from table1;
Example #2:
Create temporary table tempabc ... definition and value;
Select * from tableDEF inner join tempabc USING (tableDEF.refid = tableDEF.id) where table a=1;
This question may already be answered but I cannot find duplicates for it. If nothing in staightforward JDBC-Postgres way let me know other ways. Thanks!
This may be what you are looking for: Batch statements. The caveat is that your statements must be insert/update/delete (actions).

Alternatively, you could execute a stored proc and return cursors. More on that here: https://stackoverflow.com/a/10804730/559095
对于第一个问题,您可以使用setSchema更改搜索路径。至于第二个问题,只要您使用相同的连接,临时表就会在那里。
