Language: SQL from PostgreSQL in Amazon Redshift;
Editor: Dbeaver Community
Hello guys! I saw the example here in the community from how to declare variables in Dbeaver using the "set" statement, such as in the query below:
#set vaolink = 73401;
select distinct
creative_id,
max(partition_date) as max_date
from meta_ad_xdevice.meta_ad_creative
where name like '%${vaolink}\\_%'--VAO Link
group by
creative_id;
This query results 3 values (rows) in the creative_id column. How can I store these 3 rows in one variable? I want the result to be stored in a sigle variable and then use it in other parts of the code.
Can you please help me?
Thank you!

I have a sequence in postgreSQL database, and when I run NEXTVAL(sequence_name) query inside pgAdmin 4 it returns only one value that is correct.
However inside NestJS project that's bootstrapped with TypeORM when I run this.repo.createQueryBuilder().select("NEXTVAL(sequence_name)").execute()
It returns array of objects with all next values generated.
Example: If I have 500 rows inside the table, it will return 500 NEXTVAL values for some reason.
I've tried my best to find a solution online, but no luck.
Any ideas?
The solution was fairly simple, thanks #nbk for the comment.
This was a solution:
this.repo
.createQueryBuilder()
.where('id = (select MAX(id) FROM table_name)')
.select("nextval('sequence_name")
.getRawOne();
In Mysql I am getting Innodb_rows_inserted and Innodb_rows_deleted values using these queries
select variable from information_schema.global_status where variable_name = 'innodb_rows_inserted'
Same thing I want to achieve in postgresql. Innodb is not used in postgres so I want to get some queries to fetch total inserted and deleted rows count .Can anyone help me how to get Innodb_rows_inserted and Innodb_rows_deleted values in postgresql. Thanks in advance
I think this is a very dumb question but I just can't find how to do it.
I'm using ExecuteSQL in filemaker but I noticed the result text doesn't contain the column name, any idea how I can make the result show column name?
Thanks in advance!
You could simply add a text line to your calculation, before calling the ExecuteSQL() function, e.g.:
"SomeField,AnotherField¶"
&
Execute SQL ( "SELECT SomeField, AnotherField FROM YourTable" ; "" ; "" )
Note that you can use the GetFieldName() function to protect your calculation against fields being renamed.
You can also use a query like:
SELECT * FROM FileMaker_Fields WHERE TableName='YourTable'
to retrieve ALL field names of a table.
Wondering if there is a way to query a SQL Server database and somehow format columns to omit commas in the data if there is any.
Reason for asking is I have 10000+ records and through out the data the varchar have data like 3,25% and other 1%.
I'd prefer not to alter the data in the original table thus asking if a select with other functions would do the trick.
I have thought about selecting all the data into a temp table and stripping the commas but that is a lot of work for every time I do the query.
Any info or if its is possible please reply.
Take a look at the REPLACE function:
SELECT REPLACE(YourColumn, ',', '')
FROM YourTable
Use SQL REPLACE :
REPLACE(YourField,',','')
I am have two fields in my table:
One is Primary key auto increment value and second is text value.
lets say: xyzId & xyz
So I can easily insert like this
insert into abcTable(xyz) Values('34')
After performing above query it must insert these information
xyzId=1 & xyz=34
and for retrieving I can retrieve like this
select xyzId from abcTable
But for this I have to write down two operation. Cant I retrieve in single/sub query ?
Thanks
If you are on SQL Server 2005 or later you can use the output clause to return the auto created id.
Try this:
insert into abcTable(xyz)
output inserted.xyzId
values('34')
I think you can't do an insert and a select in a single query.
You can use a Store Procedures to execute the two instructions as an atomic operation or you can build a query in code with the 2 instructions using ';' (semicolon) as a separator betwen instructions.
Anyway, for select identity values in SQL Server you must check ##IDENTITY, SCOPE_IDENTITY and IDENT_CURRENT. It's faster and cleaner than a select in the table.
