INSERT SELECT statement in Oracle 11G

Question

I\'m trying to run a very simple sql statement in Oracle 11g.

 insert into table1 (col1, col2) values (select t1.col1, t2.col2 from oldtable1 t1, oldtable2 t         


        

Answer 1

You don't need the 'values' clause when using a 'select' as your source.

insert into table1 (col1, col2) 
select t1.col1, t2.col2 from oldtable1 t1, oldtable2 t2;

Answer 2

for inserting data into table you can write

insert into tablename values(column_name1,column_name2,column_name3);

but write the column_name in the sequence as per sequence in table ...

Answer 3

Your query should be:

insert into table1 (col1, col2) 
select t1.col1, t2.col2 
from oldtable1 t1, oldtable2 t2

I.e. without the VALUES part.

Answer 4

There is an another option to insert data into table ..

insert into tablename values(&column_name1,&column_name2,&column_name3);

it will open another window for inserting the data value..

Answer 5

Get rid of the values keyword and the parens. You can see an example here.

This is basic INSERT syntax:

INSERT INTO "table_name" ("column1", "column2", ...)
VALUES ("value1", "value2", ...);

This is the INSERT SELECT syntax:

INSERT INTO "table1" ("column1", "column2", ...)
SELECT "column3", "column4", ...
FROM "table2";
