Inserting multiple rows in a single SQL query? [duplicate]
(4 answers)
Closed 7 years ago.
I have multiple set of data to insert at once
INSERT INTO MyTable VALUES ("John", "Doe", 1234567890, "employee", "");
INSERT INTO MyTable VALUES ("Susen", "Gupta", 1234567890, "leander");
INSERT INTO MyTable VALUES ("Karn", "Share", 1234567890, "employee", "home");
I want to insert multiple rows in a single SQL statement. And can it possible to do it with different number of values.
Multi-row insert has been part of the SQL standard since SQL-92, and many of the modern DBMS' support it. That would allow you to do something like:
insert into MyTable ( Name, Id, Location)
values ('John', 123, 'Lloyds Office'),
('Jane', 124, 'Lloyds Office'),
('Billy', 125, 'London Office'),
('Miranda', 126, 'Bristol Office');
You'll notice I'm using the full form of insert into there, listing the columns to use. I prefer that since it makes you immune from whatever order the columns default to.
If your particular DBMS does not support it, you could do it as part of a transaction which depends on the DBMS but basically looks like:
begin transaction;
insert into MyTable (Name,Id,Location) values ('John',123,'Lloyds Office');
insert into MyTable (Name,Id,Location) values ('Jane',124,'Lloyds Office'),
insert into MyTable (Name,Id,Location) values ('Billy',125,'London Office'),
insert into MyTable (Name,Id,Location) values ('Miranda',126,'Bristol Office');
commit transaction;
This makes the operation atomic, either inserting all values or inserting none.
Yes you can, but it depends on the SQL taste that you are using :) , for example in mysql, and sqlserver:
INSERT INTO Table ( col1, col2 ) VALUES
( val1_1, val1_2 ), ( val2_1, val2_2 ), ( val3_1, val3_2 );
But in oracle:
INSERT ALL
INTO Table (col1, col2, col3) VALUES ('val1_1', 'val1_2', 'val1_3')
INTO Table (col1, col2, col3) VALUES ('val2_1', 'val2_2', 'val2_3')
INTO Table (col1, col2, col3) VALUES ('val3_1', 'val3_2', 'val3_3')
.
.
.
SELECT 1 FROM DUAL;
In SQL Server, you can do this:
INSERT INTO MyTable VALUES ("John", 123, "Lloyds Office"),
("Jane", 124, "Lloyds Office"),
("Billy", 125, "London Office"),
("Miranda", 126, "Bristol Office")

Example:
INSERT INTO TABLE ( USERID, USERNAME) VALUES (1,"ok1"),(2,"ok2");
As i understood ,Multiple rows insertion not allowed in Oracle Database.
Please confirm me if any other alternatives for inserting multiple records into oracle DB with above format.
Oracle only allows one row to be inserted at a time. So use two inserts:
INSERT INTO TABLE ( USERID, USERNAME)
VALUES (1, 'ok1');
INSERT INTO TABLE ( USERID, USERNAME)
VALUES (2, 'ok2');
Or use INSERT . . . SELECT:
INSERT INTO TABLE ( USERID, USERNAME)
SELECT 1 'ok1' FROM DUAL UNION ALL
SELECT 2, 'ok2' FROM DUAL;
I am sorry if my question is not clear or my query is not sufficient to help. I have a procedure that has multiple if/else statement. My goal is to insert one row if that if statements meets the criteria else go further. Something like this:
create or replace procedure abc.xyz
( i_name varchar2
,number number,
sections varchar2)
...
max_date date;
min_date date;
...
if(sum=0)
insert into abc_table
(id,name,number,sections,description,date,amount,price,source,latest_date)
select user_seq.nextval,name,number,max_date,amount,0
,'xyz',trunc(sysdate))
from abc_table x
where x.name=i_name
and x.number=i_name
and x.section=i_section;
elseif (sum>0)
insert into abc_table
(id,name,number,sections,description,date,amount,price,source,latest_date)
select user_seq.nextval,name,number,max_date,amount,0
,'xyz',trunc(sysdate))
from abc_table x
where x.name=i_name
and x.number=i_name;
and x.section=i_section;
when i run my procedure, to insert the calculated value , the values are correct but so many rows were inserted. How can I prevent from multiple insert and make only one row insert ?
You are doing it wrong.
According to the Oracle documentation, The syntax for the Oracle INSERT statement when inserting a single record using the VALUES keyword is:
INSERT INTO table
(column1, column2, ... column_n )
VALUES
(expression1, expression2, ... expression_n );
But the syntax for the Oracle INSERT statement when inserting multiple records using a SELECT statement is:
INSERT INTO table
(column1, column2, ... column_n )
SELECT expression1, expression2, ... expression_n
FROM source_table
[WHERE conditions];
reference: https://www.techonthenet.com/oracle/insert.php
from the link i shared:
If you don't want to insert duplicate:
INSERT INTO clients
(client_id, client_name, client_type)
SELECT 10345, 'IBM', 'advertising'
FROM dual
WHERE NOT EXISTS (SELECT *
FROM clients
WHERE clients.client_id = 10345);
I already have a table built in oracle.
Im trying to insert some data like this:
INSERT INTO movies_actor('name','id')
VALUES ('Nuno','2'), ('Pedro','3'), ('Jose','1');
select * from movies_actor;
I always get this error
ORA-00928: missing SELECT keyword
What am I doing wrong?
I don't think you need the single quote around your field names.
You need to do:
INSERT INTO TableName(Column1, Column2)
VALUES('Nuno', '2');
In your example, it would be:
INSERT INTO movies_actor(name, id)
VALUES ('Nuno','2');
INSERT INTO movies_actor(name, id)
VALUES ('Pedro','3');
INSERT INTO movies_actor(name, id)
VALUES ('Jose','1');
select * from movies_actor;
Another way.
insert into table
(field1, field2)
select value1, value2
from dual
union
select value3, value4
from dual
etc
You cannot insert multiple records in one statement using VALUES. You can either use Tenzin's solution or use INSERT ALL :
INSERT ALL
INTO movies_actor(name, id) VALUES ('Nuno', '2')
INTO movies_actor(name, id) VALUES ('Pedro', '3')
INTO movies_actor(name, id) VALUES ('Jose', '1')
SELECT * FROM dual;
When use a bunch of INSERT statements as below it takes forever :
INSERT INTO my_table ( col1, col2, id_col) VALUES ('val1', 'val1', (select max(my_table_ID) from my_table)+1);
If I run one by one and commit then it works fine. What is the reason?
I know sequence should be used in production. But I am writing this to insert few rows in toad.
may be
INSERT INTO my_table ( col1, col2, id_col)
VALUES ('val1', 'val1', (select max(my_table_ID)+1 from my_table));
or in pl/sql block
declare
v_max number(10);
begin
select max(my_table_id) + 1 into v_max
from my_table;
insert into my_table ( col1, col2, id_col)
values ('val1', 'val1', v_max);
end;
/
but, i don't know you task...
may be used sequence + trigger before insert?

Insert multiple rows WITHOUT repeating the "INSERT INTO ..." part of the statement?
(17 answers)
Closed 9 years ago.
I have multiple set of data to insert at once, say 4 rows. My table has three columns: Person, Id and Office.
INSERT INTO MyTable VALUES ("John", 123, "Lloyds Office");
INSERT INTO MyTable VALUES ("Jane", 124, "Lloyds Office");
INSERT INTO MyTable VALUES ("Billy", 125, "London Office");
INSERT INTO MyTable VALUES ("Miranda", 126, "Bristol Office");
Can I insert all 4 rows in a single SQL statement?
In SQL Server 2008 you can insert multiple rows using a single SQL INSERT statement.
INSERT INTO MyTable ( Column1, Column2 ) VALUES
( Value1, Value2 ), ( Value1, Value2 )
For reference to this have a look at MOC Course 2778A - Writing SQL Queries in SQL Server 2008.
For example:
INSERT INTO MyTable
( Column1, Column2, Column3 )
VALUES
('John', 123, 'Lloyds Office'),
('Jane', 124, 'Lloyds Office'),
('Billy', 125, 'London Office'),
('Miranda', 126, 'Bristol Office');
If you are inserting into a single table, you can write your query like this (maybe only in MySQL):
INSERT INTO table1 (First, Last)
VALUES
('Fred', 'Smith'),
('John', 'Smith'),
('Michael', 'Smith'),
('Robert', 'Smith');
NOTE: This answer is for SQL Server 2005. For SQL Server 2008 and later, there are much better methods as seen in the other answers.
You can use INSERT with SELECT UNION ALL:
INSERT INTO MyTable (FirstCol, SecondCol)
SELECT 'First' ,1
UNION ALL
SELECT 'Second' ,2
UNION ALL
SELECT 'Third' ,3
...
Only for small datasets though, which should be fine for your 4 records.
INSERT statements that use VALUES syntax can insert multiple rows. To do this, include multiple lists of column values, each enclosed within parentheses and separated by commas.
Example:
INSERT INTO tbl_name (a,b,c) VALUES(1,2,3),(4,5,6),(7,8,9);
