Hello,

I have 2 database in postgres, both DB are related using dblink and I need to detect that when making a change in a structure or view could affects the related DB or its views.

The changes I make and need to control are:
1- When I make a change on the structure in DB 1, for example we add a field, and forget to change it in the view or related query. In this case I need a list of views that have related to be able to update them.

2- When I make a change in views in DB 1, and I do not edit all the related queries. In this case, I need a list of queries where the view is used in order to update it.

3- When I make a change in view in DB 1 used by a dblink view in DB 2 without updated it. In this case I need to be notified that the view or structure used in dblink to be able to update it.

Is there any functionality that I can use to be able to do this type of controls?

Hi,

We are migrating from oracle to postgresql. And we faced problems while rewriting oracle procedures to postgresql functions.

We get all the data required for the endpoint from single procedure to reduce round trips to database.

for example if we want show user posts

create or replace procedure user_posts(userId IN NUMBER, noOfPosts OUT NUMBER, posts OUT sys_refcursor, postComments OUT sys_refcursor)

here we are getting noOfPosts, posts and postComments resultset from single procedure.

Searched for the equivalent procedure in postgresql but not found.

While searching for the answer I found returns table. But using returns table I am not able to achieve this. I am able to get only one of these three out parameters.

Because of this constraint now we are using three queries for noOfPosts, posts and postComments.

How can we achieve same with postgresql.

Thanks.

Hi,

 I am trying to get refcursor from postgresql procedure using spring data jpa. I am getting below error.

org.springframework.orm.jpa.JpaSystemException: No Dialect mapping for JDBC type: 1111; nested exception is org.hibernate.MappingException: No Dialect mapping for JDBC type: 1111

Here data got inserted in database but not able to get the data from.

CREATE OR REPLACE FUNCTION public.register(email text, password text, name text)
 RETURNS refcursor

AS $function$
DECLARE
	userInfo REFCURSOR;
	userId int4;

	insert into "users"(u_email, u_password, u_name)
	values(email, password, name);
	
	userId := currval('user_u_user_id_seq');

	open userInfo FOR SELECT * FROM users WHERE u_user_id = userId;

	return userInfo;
end;

Hi
I have some point data stored in a postgreSQL/PostGIS Database
I need to do some distance measurements select point within 0.5 km of my point

something like

select * from geo_table where ST_DWithin('POINT(Long Lat)' ::geography,geog,0.5)

Select all Open in new window

the problem is points are stored as Geometry Longitude, Latitude SRD= 4326

  my geo_table has geom column created from  Longitude, Latitude points and a currently empty geog column

Any idea how to  create the geography column either from the existing geography column or from the Longitude, Latitude (Stored digitally not DMS ) columns?

thank you

Hi,
 I am using PostgreSQL database for developers.Now I want to migrate the PostgreSQL database to SQL lite in windows 7.
 what should i do? Please suggest me.

Hi
I'm running PHP version 5.3.5 on a standalone (No internet) fedora 12

I need to build a search web page to query a PostgreSQL database I can't use PDO because the driver is missing

pg_connect works so how do I write a select query that can take 1 or more user parameters from a front end form and loop through the results

At this stage I'm just trying to work out how to query the database safely  eg bind the user parameters to prevent SQL Injection  

I get SQL syntax error on the where clause I think the array isn't being passed into $1

syntax error at or near "," line XX:  name like $1 , array("Trevor%")

<?php
error_reporting(E_ALL);

// Connect to a database named "mary"
$dbconn = pg_connect("dbname=mary") or die("Cannot connect ".  pg_last_error()) ;

$name = "Trevor%";  // simulate $_POST 

$SQL = <<<SQL
Select name,age,address from my_table where name like $1" , array("$name"));
SQL;
 // actual query is over multi lines

$results= pg_query($SQL) or die("Cannot connect ".  pg_last_error()) ;

if($results){
// loop through results building HTML
  while($row = pg_fetch_array($result, NULL, PGSQL_ASSOC)){
            echo "<p>Name:" . $row['name'] . "age: " .$row['age'] .  "address:" . $row['address'] . "</p>";
  }
}// end if results
else{
      echo "<p>No Data </p>";
}

Hi Team,

         I am using PostgreSQL using PGadmin 4 for Backup &restore. I can able to take backup easily using backup.And also restore the backup file to new database.

       But I can't able to overwrite database restore.If i try new database restore successfully completed.If i restore backup file to old database i get a error.I was using pg admin and lot of command also for restore.Anyone can you please help me for this issue. I am using windows 7 32 Bit.

I have 2 tables in posgreSQL something like this

table_1

id,text1,text2,text_3
1,99,012345
2,999,023456

table_2

id,text3
1,099/12345
2,999/23456 

Select all Open in new window

I need to link the 2 tables together  so on
table_1
if text1 is 2 digits I need to add  a leading zero = temp_text1
and remove the leading zero to text2  = temp_text2
without altering the text in text1 or text2 as  these are linked to another tables

then run an update command

update table_1 set text3 = concatenate(temp_text1, '/', temp_text2)  

Text3 in both table should then be the same format

xxx/xxxxx  or 123/12345

Hi
My VCenter server service on VMware virtual appliance 5.5 keeps stopping. upon investigating it looks like the database has taken all the disk space (99%).

I have followed this article and it only reclaimed a couple of gigs as now showing (97%). see screen print attached.

Can anyone tell me how I can reclaim more disk space please?

Thanks

We support a system where custom fields in the system are stored as hstore fields. Like this

select query

select udf_data from inventory

Select all Open in new window

""LocOver"=>"", "freight"=>"0", "3M Codes"=>"", "V_Partno"=>"110SP-60", "brokerage"=>"0", "Dentsply C"=>"""

Here is the data for one record. LocOver, freight, 3M Code, V_Partno, brokerge, Dentsply are the field names in the system

I want to update

I want to update the udf_data column with the values from inventory.part_no column from the udf_data V_Partno

So the update statement should be like this:

update customers
set udf_data = misc1
where udf_data ?| '{cust_type}'

But the hstore has a particular update statement like this:

update customers set udf_data = udf_data || '"cust_type"=>"test"'::hstore

Which does not work. Can anyone help?

I have a PosgreSQL database where I have an array field with 4 values.  This query will extract one value at the time

select public.addresses.address[1] from public.addresses

I'm linking the table to an Access database and the array I have above does not work there. How can I do this in Access?

Here is are my results from PostgreSQL and this is what I want to do in Access

The query is as below.
The attached file shows the existing worksheet with the columns that are output from this query.
The attached file also shows the desired worksheet, with some columns removed and the postcode column included twice, the extra postcode column to be included as the first column.
