Move SQL data from one table to another

Question

I was wondering if it is possible to move all rows of data from one table to another, that match a certain query?

For example, I need to move all table rows from Tab

You may use "Logical Partitioning" to switch data between tables:

By updating the Partition Column, data will be automatically moved to the other table:

here is the sample:

CREATE TABLE TBL_Part1
(id  INT NOT NULL,
 val VARCHAR(10) NULL,
 PartitionColumn  VARCHAR(10) CONSTRAINT CK_Part1 CHECK(PartitionColumn = 'TBL_Part1'),
 CONSTRAINT TBL_Part1_PK PRIMARY KEY(PartitionColumn, id)
);

CREATE TABLE TBL_Part2
(id  INT NOT NULL,
 val VARCHAR(10) NULL,
 PartitionColumn  VARCHAR(10) CONSTRAINT CK_Part2 CHECK(PartitionColumn = 'TBL_Part2'),
 CONSTRAINT TBL_Part2_PK  PRIMARY KEY(PartitionColumn, id)
);

GO

CREATE VIEW TBL(id, val, PartitionColumn)
WITH SCHEMABINDING
AS
     SELECT id, val, PartitionColumn FROM dbo.TBL_Part1
     UNION ALL  
     SELECT id, val, PartitionColumn FROM dbo.TBL_Part2;

GO

--Insert sample to TBL ( will be inserted to Part1 )
INSERT INTO TBL
VALUES(1, 'rec1', 'TBL_Part1');

INSERT INTO TBL
VALUES(2, 'rec2', 'TBL_Part1');

GO

--Query sub table to verify
SELECT * FROM TBL_Part1

GO
--move the data to table TBL_Part2 by Logical Partition switching technique
UPDATE TBL
  SET
      PartitionColumn = 'TBL_Part2';

GO

--Query sub table to verify
SELECT * FROM TBL_Part2
