I would like to insert some data into a table. One field I would like to get from another table, so I'm using select statement inside. This is the code:
INSERT INTO t.table1 (
id,
id_t2,
date_of_change
)
VALUES (
t.table1_seq.nextval,
SELECT s.id_id_t2 from t.table2 s where s.something='something',
TO_DATE('02/05/2017 13:43:34','DD/MM/YYYY HH24:MI:SS')
)
Although select statement is always returning only 1 field (1 row), I presume this is why I'm getting the error.
How can I write INSERT statement with SELECT statement for just 1 field? Can it be done? If not, is there any other solution for this problem? Thank you.
You can translate your whole insert statement into the form of
insert into table1 (fields)
select fields from table2
This will allow you to specify in your select some values from the source table and some constant values. Your resulting query would be
INSERT INTO t.table1 (
id,
id_t2,
date_of_change
)
SELECT t.table1_seq.nextval,
s.id_id_t2,
TO_DATE('02/05/2017 13:43:34','DD/MM/YYYY HH24:MI:SS')
FROM t.table2 s
WHERE s.something='something'

I want to insert some data into table tableA, but I have to use group by and my_sequence.nextval. It is impossible to use both in the same statment, is exists any workaround ?
For example:
insert into tableA (
taba_id,
taba_sum,
taba_date
) select
tabb_sequence.nextval,
sum(tabb_value),
tabb_date
from
tableB group by (tabb_date);
After execute this statment, I got:
ORA-02287: sequence number not allowed here
According oracle documentation,I should get this error.
How to deal with sequence and group by caluses in one statment?
The problem here is because your sequence is not aggregated, therefore you have this error. Try this way:
insert into tableA (
taba_id,
taba_date,
taba_sum
)
select tabb_sequence.nextval,
tabb_date,
stv
from (select tabb_date,
sum(tabb_value) stv,
from tableB
group by tabb_date) a;
I am creating a volatile table and trying to insert rows to the table. I can upload one row like below...
create volatile table Example
(
ProductID VARCHAR(15),
Price DECIMAL (15,2)
)
on commit preserve rows;
et;
INSERT INTO Example
Values
('Steve',4);
However, when I try to upload multiple I get the error:
"Syntax error: expected something between ')' and ','."
INSERT INTO Example
Values
('Steve',4),
('James',8);
As Gordon said, Teradata doesn't support VALUES with multiple rows (and the UNION ALL will fail because of the missing FROM.
You can utilize a Multi Statement Request (MSR) instead:
INSERT INTO Example Values('Steve',4)
;INSERT INTO Example Values('James',8)
;
If it's a BTEQ job the Inserts are submitted as one block after the final semicolon (when there's a new command starting on the same line it's part of the MSR). In SQL Assistant or Studio you must submit it using F9 instead of F5.
I don't think Teradata supports the multiple row values syntax. Just use select:
INSERT INTO Example(ProductId, Price)
WITH dual as (SELECT 1 as x)
SELECT 'Steve' as ProductId, 4 as Price FROM dual UNION ALL
SELECT 'James' as ProductId, 8 as Price FROM dual;
CTE syntax (working):
insert into target_table1 (col1, col2)
with cte as (select 1 col1)
select 'value1', 'value2' from cte
union all
select 'value1a', 'value2a' from cte
;
CTE Syntax not working in Teradata
(error: expected something between ")" and the "insert" keyword)
with cte as (select 1 col1)
insert into target_table1 (col1, col2)
select 'value1', 'value2' from cte
union all
select 'value1a', 'value2a' from cte
;
I found a solution for this via RECURSIVE. It goes like this:-
INSERT INTO table (col1, col2)
with recursive table (col1, col2) as
(select 'val1','val2' from table) -- 1
select 'val1','val2' from table -- 2
union all select 'val3','val4' from table
union all select 'val5','val6' from table;
Data of line 1 does not get inserted (but you need this line). Starting from line 2, the data you enter for val1, val2 etc. gets inserted into the respective columns. Use as many UNION ALLs' as many rows you want to insert. Hope this helps :)
At least in our version of Teradata, we are not able to use an insert statement with a CTE. Instead, find a real table (preferably small in size) and do a top 1.
Insert Into OtherRealTable(x, y)
Select top 1
'x' as x,
'y' as y
FROM RealTable
create table dummy as (select '1' col1) with data;
INSERT INTO Student
(Name, Maths, Science, English)
SELECT 'Tilak', 90, 40, 60 from dummy union
SELECT 'Raj', 30, 20, 10 from dummy
;
yes you can try this.
INSERT INTO Student
SELECT (Name, Maths, Science, English) FROM JSON_Table
(ON (SELECT 1 id,cast('{"DataSet" : [
{"s":"m", "Name":"Tilak", "Maths":"90","Science":"40", "English":"60" },
{"s":"m", "Name":"Raj", "Maths":"30","Science":"20", "English":"10" }
]
}' AS json ) jsonCol)
USING rowexpr('$.DataSet[*]')
colexpr('[{"jsonpath":"$.s","type":"CHAR(1)"},{"jsonpath":"$.Name","type":"VARCHAR(30)"}, {"jsonpath":"$.Maths","type":"INTEGER"}, {"jsonpath":"$.Science","type":"INTEGER"}, {"jsonpath":"$.English","type":"INTEGER"}]')
) AS JT(id,State,Name, Maths, Science, English)
I need to populate reqopt table which have two varchar fields (valeur, categorie), the first shoud be field from another table (mytable) and another should be a simple varchar ('prop').
I've tried this
INSERT INTO reqopt(valeur, categorie) (select distinct name from mytable , 'prop')
I got this error Incorrect syntax near 'prop'.
INSERT INTO reqopt(valeur, categorie)
select distinct name, 'prop'
from mytable
SELECT DISTINCT NAME AS valeur,'PROP' REMARKS AS categorie
INTO reqopt

I am trying to select data from one table
and insert the data into another table
SELECT ticker FROM tickerdb;
Using OracleSql I am trying to
get the ticker symbol "GOOG" from the tickerdb table,
and insert the t.ticker into the stockdb table.
select from tickerdb table --> insert into quotedb table
INSERT INTO quotedb
(t.ticker, q.prevclose, q.opn, q.rnge,
q.volume, q.marketcap, q.dividend, q.scrapedate)
VALUES (?,?,?,?,?,?,?,?,SYSDATE)
tickerdb t inner JOIN quotedb q
ON t.ticker = q.ticker
From the oracle documentation, the below query explains it better
INSERT INTO tbl_temp2 (fld_id)
SELECT tbl_temp1.fld_order_id
FROM tbl_temp1 WHERE tbl_temp1.fld_order_id > 100;
You can read this link
Your query would be as follows
//just the concept
INSERT INTO quotedb
(COLUMN_NAMES) //seperated by comma
SELECT COLUMN_NAMES FROM tickerdb,quotedb WHERE quotedb.ticker = tickerdb.ticker
Note: Make sure the columns in insert and select are in right position as per your requirement
Hope this helps!
You can use
insert into <table_name> select <fieldlist> from <tables>
try this query below:
Insert into tab1 (tab1.column1,tab1.column2)
select tab2.column1, 'hard coded value'
from tab2
where tab2.column='value';
You will get useful information from here.
SELECT ticker
INTO quotedb
FROM tickerdb;
I'm trying to write a query that extracts and transforms data from a table and then insert those data into another table. Yes, this is a data warehousing query and I'm doing it in MS Access. So basically I want some query like this:
INSERT INTO Table2(LongIntColumn2, CurrencyColumn2) VALUES
(SELECT LongIntColumn1, Avg(CurrencyColumn) as CurrencyColumn1 FROM Table1 GROUP BY LongIntColumn1);
I tried but get a syntax error message.
What would you do if you want to do this?
No "VALUES", no parenthesis:
INSERT INTO Table2(LongIntColumn2, CurrencyColumn2)
SELECT LongIntColumn1, Avg(CurrencyColumn) as CurrencyColumn1 FROM Table1 GROUP BY LongIntColumn1;
You have two syntax options:
Option 1
CREATE TABLE Table1 (
id int identity(1, 1) not null,
LongIntColumn1 int,
CurrencyColumn money
)
CREATE TABLE Table2 (
id int identity(1, 1) not null,
LongIntColumn2 int,
CurrencyColumn2 money
)
INSERT INTO Table1 VALUES(12, 12.00)
INSERT INTO Table1 VALUES(11, 13.00)
INSERT INTO Table2
SELECT LongIntColumn1, Avg(CurrencyColumn) as CurrencyColumn1 FROM Table1 GROUP BY LongIntColumn1
Option 2
CREATE TABLE Table1 (
id int identity(1, 1) not null,
LongIntColumn1 int,
CurrencyColumn money
)
INSERT INTO Table1 VALUES(12, 12.00)
INSERT INTO Table1 VALUES(11, 13.00)
SELECT LongIntColumn1, Avg(CurrencyColumn) as CurrencyColumn1
INTO Table2
FROM Table1
GROUP BY LongIntColumn1
Bear in mind that Option 2 will create a table with only the columns on the projection (those on the SELECT).
Remove both VALUES and the parenthesis.
INSERT INTO Table2 (LongIntColumn2, CurrencyColumn2)
SELECT LongIntColumn1, Avg(CurrencyColumn) FROM Table1 GROUP BY LongIntColumn1
I believe your problem in this instance is the "values" keyword. You use the "values" keyword when you are inserting only one row of data. For inserting the results of a select, you don't need it.
Also, you really don't need the parentheses around the select statement.
From msdn:
Multiple-record append query:
INSERT INTO target [(field1[, field2[, …]])] [IN externaldatabase]
SELECT [source.]field1[, field2[, …]
FROM tableexpression
Single-record append query:
INSERT INTO target [(field1[, field2[, …]])]
VALUES (value1[, value2[, …])
Remove VALUES from your SQL.
Remove "values" when you're appending a group of rows, and remove the extra parentheses. You can avoid the circular reference by using an alias for avg(CurrencyColumn) (as you did in your example) or by not using an alias at all.
If the column names are the same in both tables, your query would be like this:
INSERT INTO Table2 (LongIntColumn, Junk)
SELECT LongIntColumn, avg(CurrencyColumn) as CurrencyColumn1
FROM Table1
GROUP BY LongIntColumn;
And it would work without an alias:
INSERT INTO Table2 (LongIntColumn, Junk)
SELECT LongIntColumn, avg(CurrencyColumn)
FROM Table1
GROUP BY LongIntColumn;
Well I think the best way would be (will be?) to define 2 recordsets and use them as an intermediate between the 2 tables.
Open both recordsets
Extract the data from the first table (SELECT blablabla)
Update 2nd recordset with data available in the first recordset (either by adding new records or updating existing records
Close both recordsets
This method is particularly interesting if you plan to update tables from different databases (ie each recordset can have its own connection ...)
inserting data form one table to another table in different DATABASE
insert into DocTypeGroup
Select DocGrp_Id,DocGrp_SubId,DocGrp_GroupName,DocGrp_PM,DocGrp_DocType
from Opendatasource( 'SQLOLEDB','Data Source=10.132.20.19;UserID=sa;Password=gchaturthi').dbIPFMCI.dbo.DocTypeGroup
Do you want to insert extraction in an existing table?
If it does not matter then you can try the below query:
SELECT LongIntColumn1, Avg(CurrencyColumn) as CurrencyColumn1 INTO T1 FROM Table1
GROUP BY LongIntColumn1);
It will create a new table -> T1 with the extracted information
