Sql Server replication table

 

SELECT INTO and INSERT INTO SELECT statement to copy two kinds of table 

 1. INSERT INTO the SELECT statement

      Statement in the form of: Insert INTO Table2 (field1, Field2, ...) value1 the SELECT, value2, ... from Table1

      Table2 required target table must exist, since the target Table2 table already exists, we insert the source table Table1 except field, but also can be inserted constants. Examples are as follows:

2. 2. the SELECT INTO statement to the FROM

      Statement in the form of: the SELECT vale1, value2 INTO Table1 from Table2

      Table2 required destination table does not exist, because the table is automatically created upon insertion of Table2, and replication fields specified in Table1 data in Table2 . Examples are as follows:

 

- . 1 . Create Test Table 

    Create the Table1 TABLE 

    ( 

        A VARCHAR ( 10 ), 

        B VARCHAR ( 10 ), 

        C VARCHAR ( 10 ), 

        CONSTRAINT [PK_Table1] the CLUSTERED a PRIMARY KEY 

        ( 

            A the ASC 

        ) 

    ) the ON [a PRIMARY] 

    the GO



     - 2 . create test data 

    Insert INTO Table1 values ( ' Zhao ' , ' ASDS ' , ' 90 ' ) 

    Insert INTO Table1 values ( ' money ' ,' ASDS ' , ' 100 ' ) 

    Insert INTO Table1 values ( ' Sun ' , ' ASDS ' , ' 80 ' ) 

    Insert INTO Table1 values ( ' Li ' , ' ASDS ' , null ) 

    GO



     - 3 .Select INTO statement creates the FROM and copying the data table Table2 

    SELECT a, C the INTO Table2 from the Table1 

    the GO



     - . 4 . the results show updated 

    SELECT * from Table2

    GO

     - 5 . Delete table test 

    drop TABLE Table1 

    drop TABLE Table2
