I want to copy data from one table to another in MySQL. Table 1 (Existing table): aid st_id from_uid to_gid

I want to copy data from one table to another in MySQL.

Table 1 (Existing table):

aid    
st_id
from_uid
to_gid
to_uid
created
changed
subject
message
link

Table 2 (New Table)

st_id
uid
changed
status
assign_status

I want to copy some fields of data from T开发者_StackOverflowABLE 1 into TABLE 2.

Can this be done using MySQL queries?


This will do what you want:

INSERT INTO table2 (st_id,uid,changed,status,assign_status)
SELECT st_id,from_uid,now(),'Pending','Assigned'
FROM table1

If you want to include all rows from table1. Otherwise you can add a WHERE statement to the end if you want to add only a subset of table1.


If you don't want to list the fields, and the structure of the tables is the same, you can do:

INSERT INTO `table2` SELECT * FROM `table1`;

or if you want to create a new table with the same structure:

CREATE TABLE new_tbl [AS] SELECT * FROM orig_tbl;

Reference for insert select; Reference for create table select


You can easily get data from another table. You have to add fields only you want.

The mysql query is:

INSERT INTO table_name1(fields you want)
  SELECT fields you want FROM table_name2


where, the values are copied from table2 to table1


CREATE TABLE newTable LIKE oldTable;

Then, to copy the data over

INSERT INTO newTable SELECT * FROM oldTable;


The best option is to use INSERT...SELECT statement in mysql.

http://dev.mysql.com/doc/refman/5.0/en/insert-select.html


SELECT *
INTO newtable [IN externaldb]
FROM table1;

http://www.w3schools.com/sql/sql_select_into.asp


INSERT INTO Table1(Column1,Column2..) SELECT Column1,Column2.. FROM Table2 [WHERE <condition>]


You should create table2 first.

insert into table2(field1,field2,...)
select field1,field2,....
from table1
where condition;


You can try this code

insert into #temp 
select Product_ID,Max(Grand_Total) AS 'Sales_Amt', Max(Rec_Amount) ,'',''
from Table_Name group by Id


the above query only works if we have created clients table with matching columns of the customer

INSERT INTO clients(c_id,name,address)SELECT c_id,name,address FROM customer


IF the table is existed. you can try insert into table_name select * from old_tale;

IF the table is not existed. you should try create table table_name like old_table; insert into table_name select * from old_tale;


$sql_query= "REPLACE INTO customerdeletelist SELECT * FROM customerdetail WHERE account_number = '$account_number' && customer_number = '$customer_number' && updateDate = '$updateDate'";

$shift= mysqli_query($con, $sql_query);


If someone doing it regularly - u can try to use this tool. Unstable, but ready https://github.com/morkva-vladyslav/database-donor
