Clearly the following is incorrect.
INSERT INTO `aTable` (`A`,`B`) VALUES((SELECT MAX(`A`) FROM `aTable`)*2),'name');
I get the value:
SQL query:
INSERT INTO `aTable` (`A`, `B` )
VALUES
(
(
SELECT MAX(`A`)
FROM `aTable`
) *2
, 'name'
)
MySQL said:
1093 - You can't specify target table 'aTable' for update in FROM clause
So, I'm trying to make a bitmap table, each row corresponds to one Bit, and has a 'map' value.
To insert in the table, I don't want to do two queries, I want to do one.
How should I do this?
No one commented on this, but since I am trying to make a bitmap, it should be * 2 not ^ 2, my mistake, please note that is why the comments often say ^ 2, it was an error in the version that the commenters read.
try:
insert into aTable select max(a)^2, 'name' from aTable;
or
insert into aTable select max(a)^2, 'name' from aTable group by B;
If you need a join, you can do this:
insert into aTable select max(a)^2, 'name' from aTable, bTable;
My "Server version" is "5.0.51b-community-nt MySQL Community Edition (GPL)"
Actually, you can alias the table on the insert. I've seen this question all over the place, but no one seems to have tried that. Use a subquery to get the max from the table, but alias the table in the subquery.
INSERT INTO tableA SET fieldA = (SELECT max(x.fieldA) FROM tableA x)+1;
A more complex example, where you have a corresponding secondary key and might be inserting the FIRST record for the corresponding secondary key:
INSERT INTO tableA SET secondaryKey = 123, fieldA = COALESCE((SELECT max(x.fieldA) FROM tableA x WHERE x.secondaryKey = 123)+1,1);
By aliasing the table, it doesn't throw the error and seems to work. I just did this while coding something, although I can't see if there area any silly syntax errors above, I would try that type of syntax.
I take it that INSERT ... SELECT isn't working? I see this in the documentation for it:
The target table of the INSERT
statement may appear in the FROM
clause of the SELECT part of the
query. (This was not possible in some
older versions of MySQL.) In this
case, MySQL creates a temporary table
to hold the rows from the SELECT and
then inserts those rows into the
target table.
Out of curiosity, which version of MySQL are you using?
I think you need to drop the "VALUES", and have a valid select statement.
see this link
I'm not particularly a mySQL guy, I use MSSQL mostly. But If you format the select statement correctly, It should work.
as soon as the Select is correct you can do this.
I need to migrate data from one Database to another one, both are on the same local system.
The tables and columns got different names and I mustn't migrate all the Columns from the old Database, so
Select * doesn't work for me.
INSERT INTO newDatabase.table1(Column1, Column2);
SELECT oldDatabase.table1(column1, column2) FROM oldDatabase.table1
but all i got is a #1064 - Syntax Error
What is the error in my Query and How can i fix this ?
Thanks in advance
Your query should go like this:
INSERT INTO newDatabase.table1 (Column1, Column2)
SELECT column1, column2 FROM oldDatabase.table1;
UPDATE
Since this answer is getting more attention than I even anticipated, I should expand on this answer. First of all, it might not be obvious from the answer itself, but the columns do not need to have the same name. So, following will work too (assuming that the columns exist in their respective tables):
INSERT INTO newDatabase.table1 (Column1, Column2)
SELECT SomeOtherColumn, MoreColumns FROM oldDatabase.table1;
Furthermore, they don't even need to be real columns in the table. One of the examples for transforming data that I use quite often is:
INSERT INTO newDatabase.users (name, city, email, username, added_by)
SELECT CONCAT(first_name, ' ', last_name), 'Asgard', CONCAT(first_name,'#gmail.com'), CONCAT(first_name,last_name), 'Damir' FROM oldDatabase.old_users;
So, as it might be more obvious now, the rule is, as long as the SELECT query returns same number of columns that INSERT query needs, it can be used in place of VALUES.
INSERT INTO db1.table SELECT * FROM db2.table;
If you want to copy data to same tables of different db.
You said "The tables and columns got different names", but you still used the same names. Try this:
INSERT INTO newDatabase.newtable1 (newColumn1, newColumn2)
SELECT oldcolumn1, oldcolumn2 FROM oldDatabase.oldtable1;
CREATE TABLE db2.table LIKE db1.table;
INSERT INTO db2.table
SELECT column_name FROM db1.table
I am trying to INSERT INTO a table using the input from another table. Although this is entirely feasible for many database engines, I always seem to struggle to remember the correct syntax for the SQL engine of the day (MySQL, Oracle, SQL Server, Informix, and DB2).
Is there a silver-bullet syntax coming from an SQL standard (for example, SQL-92) that would allow me to insert the values without worrying about the underlying database?
Try:
INSERT INTO table1 ( column1 )
SELECT col1
FROM table2
This is standard ANSI SQL and should work on any DBMS
It definitely works for:
Oracle
MS SQL Server
MySQL
Postgres
SQLite v3
Teradata
DB2
Sybase
Vertica
HSQLDB
H2
AWS RedShift
SAP HANA
Google Spanner
Claude Houle's answer: should work fine, and you can also have multiple columns and other data as well:
INSERT INTO table1 ( column1, column2, someInt, someVarChar )
SELECT table2.column1, table2.column2, 8, 'some string etc.'
FROM table2
WHERE table2.ID = 7;
I've only used this syntax with Access, SQL 2000/2005/Express, MySQL, and PostgreSQL, so those should be covered. It should also work with SQLite3.
To get only one value in a multi value INSERT from another table I did the following in SQLite3:
INSERT INTO column_1 ( val_1, val_from_other_table )
VALUES('val_1', (SELECT val_2 FROM table_2 WHERE val_2 = something))
Both the answers I see work fine in Informix specifically, and are basically standard SQL. That is, the notation:
INSERT INTO target_table[(<column-list>)] SELECT ... FROM ...;
works fine with Informix and, I would expect, all the DBMS. (Once upon 5 or more years ago, this is the sort of thing that MySQL did not always support; it now has decent support for this sort of standard SQL syntax and, AFAIK, it would work OK on this notation.) The column list is optional but indicates the target columns in sequence, so the first column of the result of the SELECT will go into the first listed column, etc. In the absence of the column list, the first column of the result of the SELECT goes into the first column of the target table.
What can be different between systems is the notation used to identify tables in different databases - the standard has nothing to say about inter-database (let alone inter-DBMS) operations. With Informix, you can use the following notation to identify a table:
[dbase[#server]:][owner.]table
That is, you may specify a database, optionally identifying the server that hosts that database if it is not in the current server, followed by an optional owner, dot, and finally the actual table name. The SQL standard uses the term schema for what Informix calls the owner. Thus, in Informix, any of the following notations could identify a table:
table
"owner".table
dbase:table
dbase:owner.table
dbase#server:table
dbase#server:owner.table
The owner in general does not need to be quoted; however, if you do use quotes, you need to get the owner name spelled correctly - it becomes case-sensitive. That is:
someone.table
"someone".table
SOMEONE.table
all identify the same table. With Informix, there's a mild complication with MODE ANSI databases, where owner names are generally converted to upper-case (informix is the exception). That is, in a MODE ANSI database (not commonly used), you could write:
CREATE TABLE someone.table ( ... )
and the owner name in the system catalog would be "SOMEONE", rather than 'someone'. If you enclose the owner name in double quotes, it acts like a delimited identifier. With standard SQL, delimited identifiers can be used many places. With Informix, you can use them only around owner names -- in other contexts, Informix treats both single-quoted and double-quoted strings as strings, rather than separating single-quoted strings as strings and double-quoted strings as delimited identifiers. (Of course, just for completeness, there is an environment variable, DELIMIDENT, that can be set - to any value, but Y is safest - to indicate that double quotes always surround delimited identifiers and single quotes always surround strings.)
Note that MS SQL Server manages to use [delimited identifiers] enclosed in square brackets. It looks weird to me, and is certainly not part of the SQL standard.
Two approaches for insert into with select sub-query.
With SELECT subquery returning results with One row.
With SELECT subquery returning results with Multiple rows.
1. Approach for With SELECT subquery returning results with one row.
INSERT INTO <table_name> (<field1>, <field2>, <field3>)
VALUES ('DUMMY1', (SELECT <field> FROM <table_name> ),'DUMMY2');
In this case, it assumes SELECT Sub-query returns only one row of result based on WHERE condition or SQL aggregate functions like SUM, MAX, AVG etc. Otherwise it will throw error
2. Approach for With SELECT subquery returning results with multiple rows.
INSERT INTO <table_name> (<field1>, <field2>, <field3>)
SELECT 'DUMMY1', <field>, 'DUMMY2' FROM <table_name>;
The second approach will work for both the cases.
To add something in the first answer, when we want only few records from another table (in this example only one):
INSERT INTO TABLE1
(COLUMN1, COLUMN2, COLUMN3, COLUMN4)
VALUES (value1, value2,
(SELECT COLUMN_TABLE2
FROM TABLE2
WHERE COLUMN_TABLE2 like "blabla"),
value4);
Instead of VALUES part of INSERT query, just use SELECT query as below.
INSERT INTO table1 ( column1 , 2, 3... )
SELECT col1, 2, 3... FROM table2
Most of the databases follow the basic syntax,
INSERT INTO TABLE_NAME
SELECT COL1, COL2 ...
FROM TABLE_YOU_NEED_TO_TAKE_FROM
;
Every database I have used follow this syntax namely, DB2, SQL Server, MY SQL, PostgresQL
This can be done without specifying the columns in the INSERT INTO part if you are supplying values for all columns in the SELECT part.
Let's say table1 has two columns. This query should work:
INSERT INTO table1
SELECT col1, col2
FROM table2
This WOULD NOT work (value for col2 is not specified):
INSERT INTO table1
SELECT col1
FROM table2
I'm using MS SQL Server. I don't know how other RDMS work.
This is another example using values with select:
INSERT INTO table1(desc, id, email)
SELECT "Hello World", 3, email FROM table2 WHERE ...
Just use parenthesis for SELECT clause into INSERT. For example like this :
INSERT INTO Table1 (col1, col2, your_desired_value_from_select_clause, col3)
VALUES (
'col1_value',
'col2_value',
(SELECT col_Table2 FROM Table2 WHERE IdTable2 = 'your_satisfied_value_for_col_Table2_selected'),
'col3_value'
);
Simple insertion when table column sequence is known:
Insert into Table1
values(1,2,...)
Simple insertion mentioning column:
Insert into Table1(col2,col4)
values(1,2)
Bulk insertion when number of selected columns of a table(#table2) are equal to insertion table(Table1)
Insert into Table1 {Column sequence}
Select * -- column sequence should be same.
from #table2
Bulk insertion when you want to insert only into desired column of a table(table1):
Insert into Table1 (Column1,Column2 ....Desired Column from Table1)
Select Column1,Column2..desired column from #table2
from #table2
Here is another example where source is taken using more than one table:
INSERT INTO cesc_pf_stmt_ext_wrk(
PF_EMP_CODE ,
PF_DEPT_CODE ,
PF_SEC_CODE ,
PF_PROL_NO ,
PF_FM_SEQ ,
PF_SEQ_NO ,
PF_SEP_TAG ,
PF_SOURCE)
SELECT
PFl_EMP_CODE ,
PFl_DEPT_CODE ,
PFl_SEC ,
PFl_PROL_NO ,
PF_FM_SEQ ,
PF_SEQ_NO ,
PFl_SEP_TAG ,
PF_SOURCE
FROM cesc_pf_stmt_ext,
cesc_pfl_emp_master
WHERE pfl_sep_tag LIKE '0'
AND pfl_emp_code=pf_emp_code(+);
COMMIT;
Here's how to insert from multiple tables. This particular example is where you have a mapping table in a many to many scenario:
insert into StudentCourseMap (StudentId, CourseId)
SELECT Student.Id, Course.Id FROM Student, Course
WHERE Student.Name = 'Paddy Murphy' AND Course.Name = 'Basket weaving for beginners'
(I realise matching on the student name might return more than one value but you get the idea. Matching on something other than an Id is necessary when the Id is an Identity column and is unknown.)
You could try this if you want to insert all column using SELECT * INTO table.
SELECT *
INTO Table2
FROM Table1;
I actually prefer the following in SQL Server 2008:
SELECT Table1.Column1, Table1.Column2, Table2.Column1, Table2.Column2, 'Some String' AS SomeString, 8 AS SomeInt
INTO Table3
FROM Table1 INNER JOIN Table2 ON Table1.Column1 = Table2.Column3
It eliminates the step of adding the Insert () set, and you just select which values go in the table.
This worked for me:
insert into table1 select * from table2
The sentence is a bit different from Oracle's.
INSERT INTO yourtable
SELECT fielda, fieldb, fieldc
FROM donortable;
This works on all DBMS
For Microsoft SQL Server, I will recommend learning to interpret the SYNTAX provided on MSDN. With Google it's easier than ever, to look for syntax.
For this particular case, try
Google: insert site:microsoft.com
The first result will be http://msdn.microsoft.com/en-us/library/ms174335.aspx
scroll down to the example ("Using the SELECT and EXECUTE options to insert data from other tables") if you find it difficult to interpret the syntax given at the top of the page.
[ WITH <common_table_expression> [ ,...n ] ]
INSERT
{
[ TOP ( expression ) [ PERCENT ] ]
[ INTO ]
{ <object> | rowset_function_limited
[ WITH ( <Table_Hint_Limited> [ ...n ] ) ]
}
{
[ ( column_list ) ]
[ <OUTPUT Clause> ]
{ VALUES ( { DEFAULT | NULL | expression } [ ,...n ] ) [ ,...n ]
| derived_table <<<<------- Look here ------------------------
| execute_statement <<<<------- Look here ------------------------
| <dml_table_source> <<<<------- Look here ------------------------
| DEFAULT VALUES
}
}
}
[;]
This should be applicable for any other RDBMS available there. There is no point in remembering all the syntax for all products IMO.
INSERT INTO FIRST_TABLE_NAME (COLUMN_NAME)
SELECT COLUMN_NAME
FROM ANOTHER_TABLE_NAME
WHERE CONDITION;
Best way to insert multiple records from any other tables.
INSERT INTO dbo.Users
( UserID ,
Full_Name ,
Login_Name ,
Password
)
SELECT UserID ,
Full_Name ,
Login_Name ,
Password
FROM Users_Table
(INNER JOIN / LEFT JOIN ...)
(WHERE CONDITION...)
(OTHER CLAUSE)
select *
into tmp
from orders
Looks nice, but works only if tmp doesn't exists (creates it and fills). (SQL sever)
To insert into existing tmp table:
set identity_insert tmp on
insert tmp
([OrderID]
,[CustomerID]
,[EmployeeID]
,[OrderDate]
,[RequiredDate]
,[ShippedDate]
,[ShipVia]
,[Freight]
,[ShipName]
,[ShipAddress]
,[ShipCity]
,[ShipRegion]
,[ShipPostalCode]
,[ShipCountry] )
select * from orders
set identity_insert tmp off
IF you want to insert some data into a table without want to write column name.
INSERT INTO CUSTOMER_INFO
(SELECT CUSTOMER_NAME,
MOBILE_NO,
ADDRESS
FROM OWNER_INFO cm)
Where the tables are:
CUSTOMER_INFO || OWNER_INFO
----------------------------------------||-------------------------------------
CUSTOMER_NAME | MOBILE_NO | ADDRESS || CUSTOMER_NAME | MOBILE_NO | ADDRESS
--------------|-----------|--------- || --------------|-----------|---------
A | +1 | DC || B | +55 | RR
Result:
CUSTOMER_INFO || OWNER_INFO
----------------------------------------||-------------------------------------
CUSTOMER_NAME | MOBILE_NO | ADDRESS || CUSTOMER_NAME | MOBILE_NO | ADDRESS
--------------|-----------|--------- || --------------|-----------|---------
A | +1 | DC || B | +55 | RR
B | +55 | RR ||
If you go the INSERT VALUES route to insert multiple rows, make sure to delimit the VALUES into sets using parentheses, so:
INSERT INTO `receiving_table`
(id,
first_name,
last_name)
VALUES
(1002,'Charles','Babbage'),
(1003,'George', 'Boole'),
(1001,'Donald','Chamberlin'),
(1004,'Alan','Turing'),
(1005,'My','Widenius');
Otherwise MySQL objects that "Column count doesn't match value count at row 1", and you end up writing a trivial post when you finally figure out what to do about it.
If you create table firstly you can use like this;
select * INTO TableYedek From Table
This metot insert values but differently with creating new copy table.
In informix it works as Claude said:
INSERT INTO table (column1, column2)
VALUES (value1, value2);
Postgres supports next:
create table company.monitor2 as select * from company.monitor;
Hi I am trying to run this query below:
INSERT INTO Database2.Table2 ('1', getdate(), getdate(), '',ID,'','0','0','0','',ID,'','',getdate(),getdate(),'','0','"stackoverflow.com/"'+'ID','0','product','','0')
SELECT ID
FROM Database1.Table1;
I am inserting a new row with constant data mixed with data from another table, this case Database1.Table1 "ID". I constantly keep getting a select statement error when I try to run this code. Is there something I am overseeing or is this statement all wrong? Thank You
Put the constants into the SELECT list.
INSERT INTO Database2.Table2
SELECT '1', getdate(), getdate(), '',ID,'','0','0','0','',ID,'','',getdate(),getdate(),
'','0',CONCAT('"stackoverflow.com/"','ID'),'0','product','','0', ID
FROM Database1.Table1;
BTW, I strongly recommend you get out of the habit of using INSERT without listing the column names before the values. Depending on the specific order of columns in the table definition is very error-prone.
Also, MySQL doesn't use + for string concatenation by default, it uses the CONCAT() function.
