I am new to PL-SQL. Can anyone answered me how to write Select statement(temp table) and apply if/else on the basis of that temp table and print output line?
Sorry if you are asking my work/effort to see how far I have made it...I am looking a way to start.
Any help would be highly appreciable.

I am working with a sql query where I have fields set dynamically but few of the fields values can be null,In case its null I want to fetch all the records with that column data.
like:
Select * from users where name=:name and class=:class;
Now suppose I have got value of only name variable and not the class,So now As class variable is not there It will give a error but I want to fetch users with all the classes in that case?
I tried this but it doesnt work:
MapSqlParameterSource params = new MapSqlParameterSource();
params.addValue("name", request.params.name);
//run the query
How can I achieve this?
If parameter value is NULL then retrieve all value.
-- PostgreSQL
SELECT *
FROM users
WHERE (name = param_name OR param_name IS NULL)
AND (class = param_class OR param_class IS NULL);

Need to divide 2 varchar columns
tried cast function to convert varchar to number
I have put sample below for SQL Server. I am explicitly casting both dividend(10 below) & divisor (2 below) for clarity in the programming.
DECLARE #value1 VARCHAR(10) = '10'
DECLARE #value2 VARCHAR(10) = '2'
SELECT CAST(#Value1 AS INT) / CAST(#Value2 AS INT)

I am trying to create a stored procedure which when called will return me multiple results
so a small variation in my sql code is:
#getnames = select * from mytable order by firstname;
#getActivename = select * from #getnames where Status = 19;
but that sems to be failing and i am not sure what i am doing wrong here
Perhaps you want :
select top (1) #getActivename = firstname
from mytable
where Status = 19
order by firstname;
According to your code you don't need to use two variables you can directly express it as by using single variable.

I want to add a star * to the end of the 'DisplayName' field of any record with a category of 2. Not sure how to do this but I think this is on the right track?
UPDATE `table_name`
SET `DisplayName` = replace(DisplayName, 'old_text', 'new_text')
WHERE Category = '2';
My problem is I need to just add a space and a character at the end, not do a find and replace.
The generic SQL would be:
UPDATE `table_name`
SET `DisplayName` = CONCAT(DisplayName, '*')
WHERE Category = '2';
CONCAT() can be spelled in different ways depending on the database -- such as + or ||.

I have an INSERT/UPDATE Procedure that will only seem to update when I change the existing "name".
I added a code field to the java, and want to update the code to the existing table without having to modify the "name" because it already exists. If I modify the "name" then the "code" will get updated to that row in the table.
Can someone help me understand whats going or what I need to modify?
thanks
PROCEDURE update_things
(things IN OUT things_bean, user_id IN NUMBER)
IS
t_things things_bean;
BEGIN
-- If there is already an id set ... this is an update
IF things.ID <> 0
THEN
SELECT things_bean (ID, NAME, code, work, foo)
INTO t_things
FROM things
WHERE things.ID = ID;
IF NOT things.equals (t_things)
THEN
things.foo:= t_things.foo;
things.foo.modified_date := SYSDATE;
things.foo.modified_by := user_id;
UPDATE things
SET NAME = things.NAME,
code = things.code,
foo= things.foo
WHERE ID = things.ID;
END IF;
END update_things;
looks to me like you should check this call:
things.equals(t_things)
to make sure your code value is part of the equality check.
