I have two INSERT INTO statements to the same table...
INSERT INTO #TempTable (col1, col2, col3)
VALUES (value1, value2, value3)
INSERT INTO #TempTable (col4, col5, col6)
exec CheckComponent
how can I insert both to the same row on the #TempTable... using the current script, the 1st 3 columns are sent to row 1 while the last 3 columns are sent to row 2
This is what I getting right now:
This is what I need to get:
thank you in advance for any help you can provide...
INSERT INTO #TempTable (col1, col2, col3)
VALUES (value1, value2, value3)
UPDATE #TempTable
SET col = val , ...
WHERE pk = pkval
pk means primary key.
Couple of options here.
use an update instead of an insert for the second half of the data.
Run the EXEC CheckComponent and insert it into a different temp table. Then you can use joins to combine the data on another insert.

Consider the following schema and table:
CREATE TABLE IF NOT EXISTS `names` (
`id` INTEGER,
`name` TEXT,
PRIMARY KEY(`id`)
);
INSERT INTO `names` VALUES (1,'zulu');
INSERT INTO `names` VALUES (2,'bene');
INSERT INTO `names` VALUES (3,'flip');
INSERT INTO `names` VALUES (4,'rossB');
INSERT INTO `names` VALUES (5,'albert');
INSERT INTO `names` VALUES (6,'zuse');
INSERT INTO `names` VALUES (7,'rossA');
INSERT INTO `names` VALUES (8,'juss');
I access this table with the following query:
SELECT *
FROM names
ORDER BY name
LIMIT 10
OFFSET 4;
Where offset 4 is used because it's the rowid (in the ordered list) to the first occurance of 'R%' names. This returns:
1="7" "rossA"
2="4" "rossB"
3="1" "zulu"
4="6" "zuse"
My question is, is there an SQL statement which can return the OFFSET value (in the R case above its 4) given a starting first letter please? (I don't really want to resort to stepping() through results, counting rows, until first 'R%' is reached!)
I've tried the following without success:
SELECT MIN(ROWID)
FROM
(
SELECT *
FROM names
ORDER BY name
)
WHERE name LIKE 'R%'
It always returns single row of NULL data.
As background, this table is a phone book list and I want to provide subset of results (from main table) back to caller, starting at a initial letter offset.
Just count the rows before the string of interest:
select count(*) from names where name < 'r';
The following has a number of options. Basically your issues is that the sub-query doesn't return the roiwd hencne NULL as the minimum. However, there is no need to use the rowid directly as the id column is an alias of the rowid, so that could be used:-
SELECT name, id, MIN(rowid), min(id) -- shows how rowid and id are the same
FROM
(
SELECT rowid, * -- returns rowid from the subquery so min(rowid) now works
FROM names
ORDER BY name
)
WHERE name LIKE 'R%' ORDER BY id ASC LIMIT 1 -- Will effectivley do the same (no need for the sub-query)
Extra columns added for demonstration.
As such your query could be :-
SELECT min(rowid) FROM names where name LIKE 'R%';
Or :-
SELECT min(id) FROM names where name LIKE 'R%';
You could also use :-
SELECT id FROM names WHERE name LIKE 'R%' ORDER BY id ASC LIMIT 1;
Or :-
SELECT rowid FROM names WHERE name LIKE 'R%' ORDER BY id ASC LIMIT 1;
I have written an SQL query which amalgamates data from two separate tables with the following query:
SELECT * FROM table 1
UNION ALL
SELECT * FROM table 2
ORDER BY column 1
What I'd like to be able to do is to add a column or 'stamp' in a newly created column which details the table which each text entry originally came from. So my output would have a column which detailed the table which each row was originally from.
Essentially, the tables I have are made up of large quantities of numeric data and are hard to distinguish upon completing the Union command.
Thanks for any help.

You can select a scalar value from your selects, but you need to specify columns instead of *:
SELECT col1, col2, 'TABLE1' FROM table 1
UNION ALL
SELECT col1, col2, 'TABLE2' FROM table 2 ORDER BY column 1
You can simply add any expression(s) anywhere in the SELECT clause:
SELECT *, 1 AS SourceTable FROM Table1
UNION ALL
SELECT *, 2 AS SourceTable FROM Table2
ORDER BY Column1;
I am trying to do multiple inserts into an oracle table with data rom another table and I also use a sequence. Something like this: http://www.dbforums.com/oracle/1626242-insert-into-table-sequence-value-other-table.html
Now..in the destination table there is a primary key on the column that is being populated by the sequence and it is giving me primary key violation. My guess is that the sequence.nextval is not working for some reason. Where is the error? This is my actual query:
insert into xxxx (col1, col2, col3, col4, col5)
select SEQ_CNT.nextval, inner_view.*
from (select col1, 26, 0, 'N'
FROM yyyy WHERE col_ID = 30 AND DELETED = 'N' ) inner_view;
It seems unlikely to me that the problem is that calling nextval on the sequence is not working. It is much more likely that some other process has inserted data in the table with primary key values greater than the values currently being returned from the sequence. If you
SELECT seq_cnt.nextval
FROM dual
and compare that to the largest value of the primary key in the table
SELECT max(col1)
FROM xxxxx
my wager is that the maximum value is greater than the nextval from the sequence. If that's the case, you'd generally want to reset the sequence to the current maximum value as well as figuring out how the problematic data got inserted so that the problem doesn't happen again in the future.
the outer query will not loop, hence the sequence will not increment. try this solution below
insert into xxxx (col1, col2, col3, col4, col5)
select inner_view.*
from (select SEQ_CNT.nextval, col1, 26, 0, 'N'
FROM yyyy WHERE col_ID = 30 AND DELETED = 'N' ) inner_view;
I am using the following query to display database rows in an alphabetical order:
SELECT word_id FROM table1 ORDER BY word ASC
But I want to get values from table2, where I don't have column "word" and to sort it by column "word" which is in table1.
I want something like this:
SELECT word_id FROM table2 ORDER BY table1.word ASC
Thank you in advance.
You must connect the two tables with a join:
SELECT t2.word_id
FROM table2 t2
, table1 t1
WHERE t2.word_id = t1.word_id -- this is the join
ORDER BY t1.word ASC
I have the following query:
SELECT rowid FROM table1 ORDER BY RANDOM() LIMIT 1
And as well I have another table (table3). In that table I have columns table1_id and table2_id. table1_id is a link to a row in table1 and table2_id is a link to a row in another table.
I want in my query to get only those results that are defined in table3. Only those that have table1 rowid in their table1_id column. There may not be any columns at all referring to a certain table1 rowid so in this case I don't want to receive them.
How can I achieve this goal?
Update: I tried the following query, which doesn't work:
SELECT rowid FROM table1
WHERE rowid IN (SELECT table1_id FROM table3 WHERE table1_id = table1.rowid)
ORDER BY RANDOM() LIMIT 1
SELECT rowid FROM table1
WHERE rowid IN ( SELECT DISTINCT table1_id FROM table3 )
ORDER BY RANDOM() LIMIT 1;
This query means "choose at random a row from table1 which has an entry in table3".
Every row in table1 equal likelihood of being selected (DISTINCT) as long as it is referenced at least once in table3.
If you are trying to get more than one result, then you should remove the "ORDER BY RANDOM() LIMIT 1" clause.
Assuming you want to select more than just a rowid, you need to SELECT from a JOIN between the tables you're interested in. SQLite doesn't have the full set of standard JOIN functionality, so you'll need to re-work your query so it can use a LEFT OUTER JOIN.
SELECT table1.rowid, table1.other_field
FROM table3
LEFT OUTER JOIN table1 ON table3.table1_id = table1.rowid
ORDER BY RANDOM()
LIMIT 1;
