I'm coming from a MS SQL background using SSMS. I just recently started using Oracle / Toad at a new company and I'm finding it to be a bit finicky.
One of the things that I use to do in SSMS was select 2 queries, and then execute the statement and see the results for both.
When I attempt to run the following queries
select count(*) from table1;
select count(*) from table2;
I get the following error message back: ORA-00933: SQL Command not properly ended
Is there something in particular that I'm not doing correct?
In your tool, hit F5, you'll get your results as a script for both queries.
In the free, official GUI for Oracle Database, you can do this:
As Barbaros Özhan notes, you'll need to fix your queries first. You need to do a count() on SOMETHING - * will work.
You need to include some literal like 'x', or a symbol like * or a number 1 inside count function like count(1) or count(*) or count('x').
In your case, one of these missing operators causes ORA-00933.
The answer apparently was the button that I was selecting in Toad for Oracle / slightly incorrect SQL statement.
I was hitting the "Execute / compile statement at caret" button instead of the "Execute Script As" button.

I am trying to parameterize certain where clauses to standardized my Postgres SQL scripts for DB monitoring. But have not found a solution that will allow me to have the following script run successfully
variablename = "2021-04-08 00:00:00"
select * from table1
where log_date > variablename;
select * from table2
where log_date > variablename;
Ideally, I would be able to run each script separately, but being able to find/replace the variable line would go a long way for productivity.
Edit: I am currently using DBeaver to run my scripts
To do this in DBeaver I figured out you can use Dynamic Parameter Bindings feature.
https://github.com/dbeaver/dbeaver/wiki/SQL-Execution#dynamic-parameter-bindings
Here is a quick visual demo of how to use it:
https://twitter.com/dbeaver_news/status/1085222860841512960?lang=en
select * from table1
where log_date > :variablename;
When executing the query DBeaver will prompt you for the value desired and remember it when running another query.
I'm new with LinqPad and I would like to run two simple SQL statements at the same time so I can see the values in two tables. If I run the following individually it works but now when I run them at the same time. I get an error "invalid character".
Select * From Table1; Select * From Table2;
I found this article that suggests this format but it's not working for me.
How to run multiple SQL queries?
BTW: I'm using the free version of LinqPad 5.00.08 at the moment.
I know this is old, but I found this in my search for the same problem. (Using a SQL Server Compact database.) The way I was able to get mine to work was to add GO after each query.
SELECT * FROM Table1;
GO
SELECT * FROM Table2;
GO
You need to use Dump function
Table1.Dump();
Table2.Dump();
When using Postgres through the psql command line client, you can use tab completion in the WHERE clause. For example, a "users" table with an "email" and "age" column, you could type:
SELECT age FROM users WHERE em<TAB>
Would give you
SELECT age FROM users WHERE email
However, this doesn't work in the SELECT clause. Typing:
SELECT em<TAB>
does NOT give you
SELECT email
Of course it doesn't work because it doesn't yet know what table to peer into for the the tab completion, but is there some way to do this? I tried switching the order of the sql statement to
FROM users SELECT em<TAB>
But that neither works, nor appears to be a legal SQL statement (it throws an error when executing).
No, there is no way to do this in psql. But is supported in some IDE, i.e. https://www.jetbrains.com/idea (only ultimate edition) and valentina db studio. (I only use Intellj Idea - and psql :) - and don't know other IDEs but probably this feature is supported by the most IDEs).
In most sql databases I have seen you can do something like:
SELECT ABS(-2.4)
and I get back 2.4. Notice there is no FROM clause.
When I try to do this in OpenEdge via Squirrel and the JDBC driver I get a syntax error. Is there a way to run SELECT statements like this (sans FROM clause) via JDBC?

We have a huge SQL script involving tens of tables, subqueries, hundreds of attributes. It works perfectly in the test database but returns sql subquery returns more than 1 row error when running in the production database. The script was working perfectly up until now. The problem is, all I get is a one-line error specified above with no clues whatsoever which exact subquery causes the error which makes it near to impossible to debug. The question is, how am I supposed to know which line of the SQL causes the error? Is there any way to "debug" it line by line like you would do it in a programming language?
I am using TOAD with Oracle 11g.
Add print or DBMS_OUTPUT.PUT_LINE commands to your script to print messages. And/or use exception handlers in the script. Possibly add some variables that count or label which statement you are at, and output that in the exception handler.

Once you have found the query that causes the problem, convert it to a similar query with an appropriate group by and having count(*) > 1 so that you can see what data caused the problem. For instance if you have a correlated subquery that looks like:
(select name from names where id=foo.id)
then write a similar query
select id from names group by id having count(*) > 1
to identify the offending data.
If you have multiple subqueries in the query that produces the error, you could temporarily convert the subqueries to use temporary tables and search them all for duplicates.
