Copy table structure and data SQL statements

SELECT * into target table name from source table name

INSERT into target table name (Fld1, fld2) Select Fld1, 5 from source table name

The above two sentences are to insert the source table data into the target table , but the two sentences are different:

The first sentence (select to from) requires that the target table does not exist because it is created automatically when it is inserted.
The second sentence (insert to select from) requires that the target table exist, because the target table already exists, so we can insert a constant in addition to the field of the source table, as in the example: 5.

1: Copy table structure and data to a new table

SELECT * into destination database name. dbo. destination table name from the original table name

SELECT * Into My0735home.dbo.infoMianTest from Infomian

2: Back up part of the table column (do not write * and write out the list of columns)

Select Column Name 1, column name 2, column name 3 into destination database name. dbo. destination table name from the original table name

Select Id,title,mtype,stype,author,tel,nr to InfoMianTest2 from Infomian

3: Part of the backup table row (plus where condition)

SELECT * into destination database name. dbo. destination table name from the original table name where id<10

SELECT * into Infomiantest2 from Infomian where id<10

4: Back up part of a table column (do not write * and write out a list of columns) and a subset of rows (plus where condition)

Select Column Name 1, column name 2, column name 3 into destination database name. dbo. destination table name from the original table name where id<10

5: Copy only the structure of the table: for example: SELECT * Inot T1 from titles WHERE 1=2

6: Query results from multiple tables:

SELECT Title_id,title,pub_name into T3

From titles T INNER JOIN Publishers P

On t.pub_id=p.pub_id
