问题 I am trying to figure out how to write an INSERT INTO query with table name and column name of the source as parameter. For starters I was just trying to parametrize the source table name. I have written the following query. For now I am declaring and assigning the value of the variable tablename directly, but in actual example it would come from some other source/list. The target table has only one column. CREATE OR REPLACE FUNCTION foo() RETURNS void AS $$ DECLARE tablename text; BEGIN

问题 I am new to pl/pgsql and trying to create a dynamic query. What I have now is a basic combination of parameters for testing. When it works properly, I will gradually add more dynamic parts, to create a dynamic, all-in-one query. The problem is that this should work, but instead I see an empty search_creator as Data Output in the pgadmin4. This is the code CREATE FUNCTION search_creator(creator text) RETURNS TABLE(place_id bigint, place_geom geometry, event_name character(200)) AS $$ BEGIN

问题 Is there something like JPA Specifications for Spring Data MongoDB Repositories? If not, how can I make dynamic queries with repositories? A classic scenario could be a search form with optional fields that the user will fill. 回答1: I found myself a way. The trick can be done using QueryDSL , in the following way: First, add the QueryDSL dependencies: <dependency> <groupId>com.mysema.querydsl</groupId> <artifactId>querydsl-mongodb</artifactId> <version>${querydsl-mongo.version}</version> <

问题 I have found solutions (I think) to the problem I'm about to ask for on Oracle and SQL Server, but can't seem to translate this into a Postgres solution. I am using Postgres 9.3.6. The idea is to be able to generate "metadata" about the table content for profiling purposes. This can only be done (AFAIK) by having queries run for each column so as to find out, say... min/max/count values and such. In order to automate the procedure, it is preferable to have the queries generated by the DB,

问题 Is it possible to use Fiddler 4 to retrieve the structure of the queries sent to RavendB (C#)? In fact, I am currently using session.Query() to write queries to manage the data stored in a RavenDB database. I would like to transform all these queries into session.Advanced.DocumentQuery() queries. But, some of these queries are complex. Is it possible to use fiddler to see how RavenDB transform the session.Query() queries I run into session.Advanced.DocumentQuery() queries? If so, how can I
