Consider above queries: Group by 1 means to group by the first column and group by 1,2 means to group by the first and second column and group by 1,2,3 means to group by first second and third column.
In sql if we use 1=1 in a statement in where clause it gives the true condition then the statement is executed it will give the output, if we use 1=2 in where clause then the statement will not give output as the condition is false. Example.
A query like this can be used to ping the database. The clause: WHERE 1=0. Ensures that non data is sent back, so no CPU charge, no Network traffic or other resource consumption. A query like that can test for: server availability.
The reason you put the WHERE 1=2 clause in that SELECT INTO query is to create a field-copy of the existing table with no data. But if you don't want the data contained in Table1 , and you just want the table structure, you put a WHERE clause to filter out all of the data.
no where clauseEssentially, where 1 = 1 means no where clause. It will always be true, so all records will be returned. Some people believe, erroneously, that it makes queries go faster.
WHERE 1 is a synonym for "true" or "everything." It's a shortcut so they don't have to remove the where clause from the generated SQL.
Using "where 1=1" reduces the complexity of the code needed in dynamic sql 'where' clause generation. Otherwise, when creating the 'where' clause you would need to check if this is the first component for each component added.
“Every [SQL] data type includes a special value, called the null value,”0 “that is used to indicate the absence of any data value”.1. The null value does not indicate why a value is absent—it simply marks the places that do not have a data value.

The name "Shrek" is the romanization of the Yiddish word שרעק (shrek), or שרעקלעך (shreklekh), which came in turn from the German Schreck and meaning "fear" or "fright".
