I created a table with the query editor in pgAdmin4, added some data and I can select entries from that table. However, pgAdmin does not show that new table anywhere in the side bar under Schemas/Tables. Where else should I look?
Select the database and navigate to Object/Refresh. Then the new table appears in the side bar.

How can I view table comments in Oracle SQL Developer?
I added some comments:
COMMENT ON TABLE my_table_name IS 'Here are my table comments';
I know I can use some SQL query like SELECT * FROM user_tab_comments; to display the comments, but I am curious with it is possible to view them using Oracle SQL Developer's GUI, as we can do for column comments by opening the "Columns" tab for a given table.
You can view the table comments by going to the "Details" tab and scrolling down:
Alternatively, you can right-click on the table, and select Table > Comment:
The second solution also allows you to edit the comment.
In a MySQL database I can change a table structure with an ALTER statement but how to do that in PostgreSQL with pgAdmin III? In pgAdmin III every time I drop the table and again run the updated create query of that table. Is is possible to ALTER the table in the PostgreSQL database using pgAdmin III?
Server -> Database -> Schema -> Table -> Right Click On Table -> Properties...
Step1 :
Step2 :
Step3 :
Last step is Save your changes...
In pgAdmin III you basically have two options to alter a table structure:
In the hierarchy to the left, navigate to the table and use the context menu (right-click with the mouse) to access the properties of the table. In the pop-up dialog you can make the changes. You can also drill down in the hierarchy to the individual columns and make changes to column names, data types, column constraints, etc.
After you connect to the database, you see a SQL button in the top button bar. Clicking that opens up a SQL console and you can type in an ALTER statement using standard SQL syntax.
Note that pgAdmin III does not refresh the tree hierarchy on the left of the screen after making changes through the SQL console, you have to do that manually. Right click on a node and click "Refresh" to update the information in that node and everything under that node. (So if you made changes to a single table, r-click on the table name, if multiple tables are affected r-click on the schema name, etc.)
In pgAdmin, When I am open view table data, popup window are opened with title: edit table data without primary key, please see screenshot.
I add primary key column on table:
alter table users add column id bigserial primary key
though, this popup window still opened, when trying view table data.
Cann you tell me please what is wrong here?
postgresql version is 9.3
pgAdmin version is 1.18.1
pgAdmin takes a look at the database when you open it and then you are working with that snapshot. Any changes made will only be visible to pgAdmin after you do a "refresh". This is a right-click menu option on most objects in the object tree.
So even while you know you have changed the table and the changes are in the database (you can use the SQL editor to verify that), pgAdmin doesn't - an object tree refresh (in your case on your table users) fixes that.
I am new to postgreSQL. Is there any way to insert row in postgreSQL pgAdmin without using SQL Editor (SQL query)?
The accepted answer is related to PgAdmin 3 which is outdated and not supported.
For PgAdmin 4 and above, the application is running in the browser.
After you create your table, you have to make sure that your table has a primary key otherwise you couldn't edit the data as mentioned in the official documentation.
To modify the content of a table, each row in the table must be
uniquely identifiable. If the table definition does not include an OID
or a primary key, the displayed data is read only. Note that views
cannot be edited; updatable views (using rules) are not supported.
1- Add primary key
Expand your table properties by clicking on it in the pgAdmin4 legend. Right-click on 'Constraints', select 'Create' --> 'Primary Key'to define a primary key column.
2- View the data in excel like format
Browser view, right-click on your table --> select View/Edit Data --> All Rows
3- Add new row / Edit data
On the Data Output tab at the bottom of the table below the last row, there will be an empty row where you can enter new data in an excel-like manner. If you want to make updates you can also double click on any cell and change its value.
4- Save the changes
Click on the 'Save' button on the menu bar near the top of the data window.
I think some answers don't provide an answer to the original question, some of them insert records but with SQL statements and the OP clearly said WITHOUT, so I post the right answer: (Step by Step)
Alternatively you can use the query tool:
INSERT INTO public.table01(
name, age)
VALUES (?, ?);
use the lightning icon to execute.
You can do that without the SQL editor, but it's better to do this by queries.
Although, in pgAdmin, there is an option which you can click to have an excel-like window where you can add and update data in a table without using SQL language. Please select a table which you want to add a row first and click on the next icon here below.
Editing table data without primary key is forbidden
If your tables don't have a primary key or OIDs, you can view the data only.
Inserting new rows and changing existing rows isn't possible for the Edit Data tool without primary key.
Use INSERT:
INSERT INTO tablename (field1, field2) values ('value1', 2);
on pgAdmin 4, right-click on the table and use the item like below. You can also use that script in the background.
Finally, to watch the inserted data do like below. You can also use that script in the background.
All the above are correct answers. I just want to add that : When u create a table, make sure u have atleast one column as PRIMARY_KEY. Then, just follow the GUI : View/Edit data. U can add row as the last row of the table
As an update, the icon for the save button is different in pgAdmin 4.
This is how the menu should look after right-clicking on the table you want to insert into and hovering over "View/Edit Data".
After adding rows, either press F6 (on Ubuntu) or click the icon that looks like a stack of discs (database icon) with a lock on it.

I've searched through all of the responses on SQL Developer and I haven't found a response that matches this question. I need to be able to see the SQL for a table/view etc by clicking on the sql tab, but for now it simply shows me a blank screen. Has anyone else solved this? It works fine in toad and I can see the code but we have a new server and I can't connect to it with toad. Any help would be nice.
When i connect to SQL Developer and type alter the session set current_schema=xyz then i am connect as if i was that user.
When i open the branche other users, and navigate to a table of user xyz, and click table A_TABLE, then i see the definition of that table in the columns tab and i have several other tabs, such as data to show the data in the table. So far so good.
But when i navigate to the SQL tab (on the far right of the tabs) i would expect to see the DLL of the table, but this tab stays empty. (this is also posted in another thread, but no good solution)
Is there a way to get this working ?
Probably tab in the backend looks in user_tables and user_tab_columns to generatie the DLL.
And since i did an alter session, the table are probably in the all_tables view.
It works fine when i log in and click my own tables, but not that of other users.
Same think with view definitions.
Also right clicking on the object and choose quick DLL results in empty file/worksheet of clipboard.
In short, can the tab SQL only work for schema owners of dba's or can it also work when using alter session set current_schema = xyz
Not sure exactly what you mean, but:
1. Can you connect to your db using Sqldev? Can you expand the list of schema objects and see your tables?
2. If so then when you open a sql worksheet, yes it is blank., this is where you type your sql statement and execute it. Type the FROM clause first, then go back and add the select clause and sql dev will show a drop down list of columns for the tables you can select from w/o typing the col names.
3. If you want to see you table data, simply double click the table in the tree browser on the left.
You can also build queries graphically though drag and drop.
But, normal behavior of the SQL worksheet window is to display blank, so not sure exactly what you expecting to happen.
If you select a view and right click and select Export DDL and Select Save to Worksheet, then the DDL is pasted into a worksheet: Example:
CREATE TABLE "HR"."COUNTRIES"
( "COUNTRY_ID" CHAR(2 BYTE) CONSTRAINT "COUNTRY_ID_NN" NOT NULL ENABLE,
"COUNTRY_NAME" VARCHAR2(40 BYTE),
"REGION_ID" NUMBER,
CONSTRAINT "COUNTRY_C_ID_PK" PRIMARY KEY ("COUNTRY_ID") ENABLE,
CONSTRAINT "COUNTR_REG_FK" FOREIGN KEY ("REGION_ID")
REFERENCES "HR"."REGIONS" ("REGION_ID") ENABLE
) ORGANIZATION INDEX NOCOMPRESS PCTFREE 10 INITRANS 2 MAXTRANS 255 LOGGING
STORAGE(INITIAL 65536 NEXT 1048576 MINEXTENTS 1 MAXEXTENTS 2147483645
PCTINCREASE 0 FREELISTS 1 FREELIST GROUPS 1 BUFFER_POOL DEFAULT)
TABLESPACE "USERS"
PCTTHRESHOLD 50;
SQL DDL statements show the 'code' to create the schema object.
