I use sql 2012 but, one can answer up to 2019

create table t ( b decimal(13,4) not null, c decimal(13,4) not null);
Insert into T (B,C) values ( 1,200);
Insert into T (B,C) values (   200   ,400);
Insert into T (B,C) values (  600,   900);

create table t1 (b decimal(13,4) not null, c decimal(13,4) not null);
Insert into t1 (B,C) values ( 1,100);
Insert into t1 (B,C) values (  200   ,500);
Insert into t1 (B,C) values (  800,   1000);

-- "t" and "t1" table holds ranges which could be any thing where b<c, i have to find out where "t" has range but "t1" does not?
--ex "t"  has 1,200 , "t1"  1,100  so i want to see 100 to 200 t2 does not have any thing.

Q) i have to find out the range where "t" has got range but "t1" does not? that means start range and end range will be passed

and i have to find out the range where "t1" is not done but "t" is done

-- case 1 table "t" and "t1" will have no overlap  with in the table

-- case 2 they will have overlap with in the table.

result

100 -200

600 - 800

Off the top of my head, that sounds like a variation of the "gaps and islands" problem. In T-SQL you can use window functions (or other ways) to solve the basic problem, maybe you can extend that approach. Look here, for example: https://www.red-gate.com/simple-talk/sql/t-sql-programming/the-sql-of-gaps-and-islands-in-sequences/

You need to identify any ranges not included between 0 and 1. Note that some ranges do overlap. The exclusivity of the endpoints is not relevant for use case; You only need to identify what the endpoints of the gaps.

Here is the table structure:

DECLARE @ CheckRegister TABLE
(
AccountNumber Varchar(10),
CheckNumber Varchar(10)

Lordy... the spammers sure had a field day on this one.

DerFredo cited a really good link by Dwain Camps on the subject.  Other than my posts, it's also the only post that has nothing to do with the spam that the others have written.  I'm not even going to mention the subject of the spam the others have written for fear of the damned bots and human moroffs posting more spam.

Cannabis seeds collecting is one of the most rewarding parts of gardening. Not only are you able to take care of yourself by tending to your plants and harvesting the fruits of your labor, but you are also able to preserve the seeds that grow from them. These seeds can be used to create a new crop or to save your favorite varieties for future use.

As a first step, it's important to understand that not all plant species can produce viable seeds. This includes many types of wildflowers and some vegetables, so be sure to check the label first. In addition, each seed has its own requirements for conditions before it can germinate. Some need cold temperatures, while others prefer warmth in order to develop properly. Make sure you're taking care of these conditions when collecting seeds to increase their chance of success.

Once you have collected enough seeds for your garden, it's time to start planting them! Take care not to plant them too early as they may rot in the ground before they have a chance to sprout. You should also make sure that they are planted in well-draining soil with good drainage as this will ensure they don't rot in their pots or containers. Once they reach a certain size, you can transplant them into larger containers so they have room to grow into mature plants.
