I have the attached table structure :
How do I select all the columns from this table as I want the output to be:
msg_src_id ,cntry_cd ,hldr_org_addrs ,hldr_idv_tins ,hldr_idv_nms ,pmts
Thanks!

I have column "elements" in table which is having a json(array json) row values which looks like this
elements
[{"key":12,"value":"qw"},{"key":13,"value":"fa"}]
[{"key":32,"value":"24"},{"key":321,"value":"21"}]
I want to make an column of arrays for every row which consist of keys extracted from that row's json values ,my desired column "result" may look like this
elements
result
[{"key":12,"value":"qw"},{"key":13,"value":"fa"}]
{12,13}
[{"key":32,"value":"24"},{"key":321,"value":"21"}]
{32,321}
is there a way to do it? thank you
Schema (PostgreSQL v13)
CREATE TABLE test (
elements json
);
INSERT INTO test VALUES ('[{"key":12,"value":"qw"},{"key":13,"value":"fa"}]');
INSERT INTO test VALUES ('[{"key":32,"value":"24"},{"key":321,"value":"21"}]');
Query #1
select elements::text, array_agg(cast(value->>'key' as integer)) as result
from test, json_array_elements(elements)
group by 1
ORDER BY 1;
elements
result
[{"key":12,"value":"qw"},{"key":13,"value":"fa"}]
12,13
[{"key":32,"value":"24"},{"key":321,"value":"21"}]
32,321

select elements::text,

I have a scenario, where 100's of select statements sql's are in one metadata table or some text file.
Need to insert all sql results into one specific table. (master table has col1, col2,col3 .... 200columns )
problem im facing(ORA-00947) is every select statement has different number of columns.
.. i need to generate INSERT PART.
CASE 1 : INSERT INTO (COL1,COL2,COL3) <<this select part comes from file/variable>>
CASE 2 : INSERT INTO (COL1) <<this select part comes from file/variable>>
CASE 3 : INSERT INTO (COL1) <<this select part comes from file/variable>>
have to figure out how many columns are in select part then generate INSERT part.
.
Thought of create as select but problem is some select statement has max(col) without alias so it will fail.
This is too long for a comment.
If you are storing SQL in a table, then you are constructing your query dynamically. So, update the table and list the columns that you want.
You could then construct the inserts as :
insert into master_table (<column list here>)
<select here>;
Both the select and column list would come from the table.
By far the easiest is to create a view for each SELECT statement. Then you can query the USER_TAB_COLUMNS view on the view name and get the column names.

I have a table that was created importing data from an Excel spreadsheet. The table currently looks like this:
I would like to either retrieve the column name from every row or either create a new table with a couple of columns, Data and ColumnName
So, being more clear, ABAS-3 for example is under ClinicalPsycology column, I'd like to create a temporary table or at least return in a query the column name for ABAS-3.
The ideal for me would be to create a temporary table that looks like this:
Data ColumnName
---------------------------
ABAS-3 ClinicalPsycology
ADHDT-2 ClinicalPsycology
AAB SpecialEducation
SAGES-3 Counseling
... and like that.. is that possible?
A general way to do this in any database is to use union all:
select ClinicalPsycology as data, 'ClinicalPsycology' as column
from t
union all
select SpecialEducation as data, 'SpecialEducation' as column
from t
union all
. . .;
Some databases support lateral joins (via the lateral or apply keywords). Such methods would be more efficient than using union all on each column.
In Table A i have many fields like referenceid, amount, timestamp, remarks, status, balancebefore, balanceafter, frmsisdn, tomsisdn, id etc etc
I want to create a new table, Table B based of Table A(with column names, datatypes etc etc) but i only need specific columns that are in table A.
I tried select * into TableB from TableA where 1 = 2 but it says ORA-00905: missing keyword. I am using TOAD.
thank you
In Oracle, the correct syntax is create table as. SELECT INTO is used primarily in SQL Server and Sybase.
create table tableb as
select . . .
from tableA;
Only include the where clause if you don't actually want to insert any rows.
In MySQL the syntax is the same as Oracle's (see here).
Notice that the new table does not contain any constraints from the original table (indexes, keys, etc.)
I had to make a new table to get the Include statement working in Entity Framework since EF was looking for a table called be_PostTagbe_Posts. I was using EF Code First from DB. But now the question is about SQL. I added one row of data and now the include works. But what I am looking for is a SQL command that can copy data from 1 column in 1 table and 1 column in another into the new be_PostTagbe_Posts table. In the be_Posts table I need the data in PostRowID to go into be_Posts_PostRowID and PostTagId to go into be_PostTag_PostTagID. Both be_PostTag_PostTagID and be_Posts_PostRowID are in the new be_PostTagbe_Posts table. I am not very good with SQL so not sure how to do this.
Edit: Thanks for the answers. I tried 2 separate queries but only data was inserted into the the be_PostTag_PostTagID while be_PostTag_PostRowID remained null.
And I tried this query which returned The multi-part identifier "be_PostTag.PostID" could not be bound.
INSERT INTO be_PostTagbe_Posts(be_PostTag_PostTagID, be_Posts_PostRowID)
SELECT be_PostTag.PostTagID, be_Posts.PostRowID
WHERE be_PostTag.PostID = be_Posts.PostID
EDIT:
This only inserted half the data - even 2 inserts leave one column null
INSERT INTO be_PostTagbe_Posts (be_Posts_PostRowID)
SELECT PostRowID FROM be_Posts;
INSERT INTO be_PostTagbe_Posts (be_PostTag_PostTagID)
SELECT PostTagID FROM be_PostTag;
And yet management studio tells me the query executed successfully but one column is still null. Weird.
Here are screenshots of the tables:
SELECT PostTagID AS be_PostTag_PostTagID, PostRowID AS be_Posts_PostRowID
INTO be_PostTagbe_Posts
FROM be_PostTag
Inner JOIN be_Posts
ON be_PostTag.PostID=be_Posts.PostID
That command created the new table with the 2 columns populated.
If i understand you ,you want to Copy Table Z's Column A to Table X And Table Z's Column B to Table Y.
If it is so, According to your question it is not clear about Table Structure of TableX and TableY
Assuming TableX And TableY to single ColumnTable [Apart from IdentityColumn] our query will be
INSERT INTO TableX
SELECT ColumnA FROM TableZ
INSERT INTO TableY
SELECT ColumnB FROM TableZ
Rest put your Entire Structure of Table To Get More Help Because These query are on Assumptions
There's not enough information in your question to give you a working example, but this would be the general syntax for INSERTing into a different table using a query SELECTing from two other tables.
INSERT INTO destination_table(wanted_value_1, wanted_value_2)
SELECT table_1.source_field_1, table_2.source_field_1
WHERE table_1.matching_field = table_2.matching_field
There has to be some sort of relationship between the two tables for the WHERE clause to work in that statement. I'm guessing based the little information you provided that there is a PostRowID field somewhere in the table that contains the tags such that your data would look similar to this in the tag table:
PostRowID PostTagID
--------- ---------
1 1
1 2
1 3
1 4
2 1
2 2
3 3
4 4
It sounds like you should use two sql statements:
Insert into `be_PostTagbe_Posts` (`be_PostTag_PostTagID`)
select `PostTagID` from POSTTAGIDTABLE
and
Insert into `be_PostTagbe_Posts` (`be_Posts_PostRowID`)
select `PostRowID` from POSTTAGIDTABLE
unless the items have some sort of relationship, then if you have a select statement that will select the merged data in two columns you can just do
Insert into `be_PostTagbe_Posts` (`be_PostTag_PostTagID`,`be_Posts_PostRowID`)
(select statement that selects the two items)
