Forgive me as I'm relatively new to SQL. But I'm trying to take modified data from a SELECT query on one table, and use it to populate data into another table.
SELECT ID FROM TABLE WHERE VALUE=10
I want to insert the resultant ID's into another Table, but with modifications such that the value is:
1stString.ID.2ndString
I've found answers for how to use the ID from the SELECT in the insert, but I can't seem to get it working when trying to concatenate. There are also other values that I'm inserting, but they're literals (I'm trying to initialize default key settings for the ID's given in another table.
Using MS SQL Studio 2008, btw.
INSERT INTO table (field)
SELECT '1stString.' + cast(id as varchar(50)) + '.2ndString'
FROM table2
WHERE id = 10
Edit - response to comment:
You're on the right track, but you want to select your hard-coded strings from your table, like this:
INSERT INTO table1 (field1, field2, field3)
SELECT '1stVal', '2ndVal', '1stString.' + cast(id as varchar(50)) + '.2ndString'
FROM table2
WHERE id = 10
This is also illustrated in Dustin Laine's answer.
INSERT INTO table1
(
f1, f2, f3, f4
)
SELECT f1, f2, f3, 'defaultval' as f4
FROM table2
WHERE value = 1

There is a db2 database with two tables. The first one, table1, has autoincrement column ID. It is the foreign key for the table2.
A am writing an HTML generator for SQL queries. So with some input parameters it generates a query or multiple queries. It is not connected to the database.
What I need is to get that autoincrement field and use it in next queries.
So basically, the scenario is:
insert into table1;
select autogenerated field ID;
insert into table2 using that ID;
insert into table2 using that ID;
...some more similar inserts...
insert into table2 using that ID;
And all that SQL query should be generated and then used as a single SQL script.
I was thinking about something like this:
SELECT ID FROM FINAL TABLE (INSERT INTO Table1 (t1column1, t1column2, etc.)
VALUES (t1value1, t1value2, etc.))
But I don't know, how I can write the result into a variable so I could use it in next queries like this:
INSERT INTO Table2 (foreignKeyCol, t2column1, t2column2, etc.)
VALUES ($ID, t2value1, t2value2, etc.)
I could just paste that select instead of $ID, but the second query can be used several times with the same $ID and different values.
EDIT: DB2 10.5 on Linux.
You can chain several inserts together using CTEs, like so:
WITH idcte (id) as (
SELECT ID FROM FINAL TABLE (
INSERT INTO Table1 (t1column1, t1column2, etc.)
VALUES (t1value1, t1value2, etc.)
)
),
ins1 (id) as (
SELECT foreignKeyCol FROM FINAL TABLE (
INSERT INTO Table2 (foreignKeyCol, t2column1, t2column2, etc.)
SELECT id, t2value1, t2value2, etc.
FROM idcte
)
),
-- more CTEs
SELECT foreignKeyCol FROM FINAL TABLE (
-- your last INSERT ... SELECT FROM
)
Essentially you will have to wrap each INSERT into a SELECT FROM FINAL TABLE for this to work.
Alternatively, you can use a global variable to keep the ID value:
CREATE VARIABLE myNewId INT;
SET myNewId = (SELECT ID FROM FINAL TABLE (
INSERT INTO Table1 (t1column1, t1column2, etc.)
VALUES (t1value1, t1value2, etc.)
));
INSERT INTO Table2 (foreignKeyCol, t2column1, t2column2, etc.)
VALUES (myNewId, t2value1, t2value2, etc.);
DROP VARIABLE myNewId;
This assumes a recent version of Db2 for LUW.
I've found that Access doesn't allow Insert Into queries for multiple records unless using a Select query from a one row table. Still, it doesn't work and I'm not sure what I'm missing.
I'm trying to insert into tblTarget, which contains 3 fields: ID, F1, F2 (Respectively auto number, number, number).
I have created a table onerow. I'm not exactly sure how it should be created, so right now it has the fields: ID, F1, F2 (Identical fields to the target table), with only one row (Empty row, except for the ID). Note that I haven't programmed the table to allow only one row, it just has only one at the moment.
The query:
INSERT INTO tblTarget (F1, F2)
SELECT * FROM (
SELECT '31','3' FROM onerow
UNION ALL
SELECT '31','2' FROM onerow);
Error I receive: "The Insert Into statement contains the following unknown field name: 'Expr1000'. Make sure you have typed correctly, and try the operation again.
My instincts say the problem is with the onerow table, but I can't figure out the solution.
This works for me in Access 2010:
INSERT INTO tblTarget (F1, F2)
SELECT *
FROM
(
SELECT 31 AS F1, 3 AS F2 FROM onerow
UNION ALL
SELECT 31, 2 FROM onerow
)
The trick was to specify the field names in the first of the UNION-ed queries so the names matched those in the INSERT clause.
try like this:
Insert into UserData(UserName,Password)
Select 'user1','abc'
Union All
Select 'user2','abc'
I need retrieve a value of columm with SELECT. But, I have multiple values ...
I don't know what the user go select in checkbox...
Ex:
Insert Into MyTable (dados) Values ('a1') I want the result = Angulo 1
Insert Into MyTable (dados) Values ('a2';'a3') I want the result = Angulo 2
Insert into MyTable (dados) Values ('a3'; a1) I want the result = Angulo 3; Angulo 1
Insert into MyTable (dados) Values ('a6'; 'a7'; 'a4') I want the result = Angulo 6; Angulo 7;Angulo4
I am Trying with SELECT CASE WHEN. But it still fails...
I suspect you are asking how to use the IN keyword in your SELECT statements? It is a little unclear what you are trying to do.
Try this:
SELECT *
FROM MyTable
WHERE dados IN ('a6','a7','a4')
Assuming you have a table named MyTable and a column named dados with 3 rows in that table for a6, a7 and a4, this will return all the matches (in this case, all three rows).
Good luck.
When you say:
insert into MyTable(dados)
Values ('a6', 'a7', 'a4')
You are saying "I have one column to put data into called dados." Then, you are providing three values. This will fail in any database (even apart from the fact that the semicolons should be commas).
Perhaps you want:
insert into MyTable(dados)
Values ('a6;a7;a4')
That is only one value, a string.
This suggests a denormalized database. You might want three different rows in a table, one for each value, connected together by some key.
here are some examples if you're using sql server 2008 and above:
if(OBJECT_ID('tempdb..#dados') is not null)
DROP TABLE #dados
select top 100 * INTO #dados FROM
(
values(1,2,3),
(4,5,6),
(7,8,9)
) t(a,b,c)
select * FROM #dados
INSERT INTO #dados (a,b,c)
values(11,22,33),
(44,55,66),
(77,88,99)
SELECT * FROM #dados
INSERT INTO #dados (a,b,c)
SELECT * FROM
(
values(111,222,333),
(444,555,666),
(777,888,999)
) t(a,b,c)
SELECT * FROM #dados
If you want to insert multiple rows (not columns) the syntax is
Insert Into
MyTable (dados)
Values
('a1'),
('a2')
Looks like you're trying to ask for two things.
How to insert multiple values would be done in the following way:
Insert Into MyTable (dados) Values ('a6'),('a7'),('a4')
If you want to return the actual values 'Angulo' + the number, you can use the following:
CREATE TABLE MyTable
(
Dados varchar(255)
)
Insert Into MyTable (dados) Values ('a12')
Insert Into MyTable (dados) Values ('a2'),('a3')
Insert Into MyTable (dados) Values ('a3'),('a1')
Insert Into MyTable (dados) Values ('a6'),('a7'),('a4')
SELECT 'Angulo'+ SUBSTRING(dados,PATINDEX('%[0-9]%',dados),LEN(dados))
FROM MyTable
It will find the first number (assuming it's always the first number you're after) and get the rest of them. It will then append it with the prefix 'Angulo' (e.g Angulo1, Angulo7, etc)
If these aren't what you're after. Please can you explain further what you need.
I'm attempting to select a table of data and insert this data into another file with similar column names (it's essentially duplicate data). Current syntax as follows:
INSERT INTO TABLE1 (id, id2, col1, col2)
SELECT similiarId, similiarId2, similiarCol1, similiarCol2
FROM TABLE2
The problem I have is generating unique key fields (declared as integers) for the newly inserted records. I can't use table2's key's as table1 has existing data and will error on duplicate key values.
I cannot change the table schema and these are custom id columns not generated automatically by the DB.
Does table1 have an auto-increment on its id field? If so, can you lose similiarId from the insert and let the auto-increment take care of unique keys?
INSERT INTO TABLE1 (id2, col1, col2) SELECT similiarId2, similiarCol1, similiarCol2
FROM TABLE2
As per you requirement you need to do you query like this:
INSERT INTO TABLE1 (id, id2, col1, col2)
SELECT (ROW_NUMBER( ) OVER ( ORDER BY ID ASC ))
+ (SELECT MAX(id) FROM TABLE1) AS similiarId
, similiarId2, similiarCol1, similiarCol2
FROM TABLE2
What have I done here:
Added ROW_NUMBER() which will start from 1 so also added MAX() function for ID of destination table.
For better explanation See this SQLFiddle.
Im not sure if I understad you correctly:
You want to copy all data from TABLE2 but be sure that TABLE2.similiarId is not alredy in TABLE1.id, maybe this is solution for your problem:
DECLARE #idmax INT
SELECT #idmax = MAX(id) FROM TABLE1
INSERT INTO TABLE1 (id, id2, col1, col2)
SELECT similiarId + #idmax, similiarId2, similiarCol1, similiarCol2
FROM TABLE2
Now insert will not fail because of primary key violation because every inserted id will be greater then id witch was alredy there.
If the id field is defined as auto-id and you leave it out of the insert statement, then sql will generate unique id's from the available pool.
In SQL Server we have the function ROW_NUMBER, and if I have understood you correctly the following code will do what you need:
INSERT INTO TABLE1 (id, id2, col1, col2)
SELECT (ROW_NUMBER( ) OVER ( ORDER BY similiarId2 ASC )) + 6 AS similiarId,
similiarId2, similiarCol1, similiarCol2
FROM TABLE2
ROW_NUMBER will bring the number of each row, and you can add a "magic value" to it to make those values different from the current max ID of TABLE1. Let's say your current max ID is 6, then adding 6 to each result of ROW_NUMBER will give you 7, 8, 9, and so on. This way you won't have the same values for the TABLE1's primary key.
I have asked Google and it said to me that Sybase has the function ROW_NUMBER too (http://infocenter.sybase.com/help/index.jsp?topic=/com.sybase.help.sqlanywhere.12.0.1/dbusage/ug-olap-s-51258147.html), so I think you can try it.
If you want to make an identical table why not simply use (quick and dirty) Select INTO method ?
SELECT * INTO TABLE2
FROM TABLE1
Hope This helps.
Make the table1 ID IDENTITY if it is not a custom id.
or
Create new primary key in table1 and make it IDENTITY, and you can keep the previous IDs in the same format (but not primary key).
Your best bet may be to add an additional column on Table2 for Table1.Id. This way you keep both sets of Keys.
(If you are busy with a data merge, retaining Table1.Id may be important for any foreign keys which may still reference Table1.Id - you will then need to 'fix up' foreign keys in tables referencing Table1.Id, which now need to reference the applicable key in table 2).
If you need your 2nd table keep similar values as in 1st table , then donot apply auto increment on 2nd table.
If you have large range, and want easy fast make and don't care about ID:
Example wit CONCAT
INSERT INTO session(SELECT CONCAT("3000", id) as id, cookieid FROM `session2`)
but you can using also REPLACE
How could I, in SQL Server 2008, write a SQL statement that would insert one row for each distinct value it finds in one column in the same table?
Edit:
The table I want to add rows to the same table I'm checking.
I have normalized table with a column [Name], and [Hobby], so how do I insert one new hobby for each name?
Input greatly appreciated =]
try
INSERT INTO TargetTable (SomeColumn)
SELECT DISTINCT TheSourceColumn From SomeSourceTable;
IF that is not what you are looking for please provide more details like what the data model looks like etc.
UPDATE - after edit from OP:
I am not sure that you data model is good but you can do this:
INSERT INTO TheTable (NAME, HOBBY)
SELECT DISTINCT X.NAME, #SomeHOBBY FROM TheTable X;
You could use something like
Insert into table1
Select distinct col1 from tabl2
The above should work as long as table1 has just one column of the same data type as col1 of tabl2
