Can't figure out why I can't perform this join, I've done many like it in the past. Am I missing something?
SELECT *
FROM THB_View.PCM_PCM_BASE base
LEFT OUTER JOIN THB_View.PCM_PCM_BASE_REOCCUR rec
LEFT OUTER JOIN THB_View.ATV atv ON base.PCM_TAG = atv.ATV_OCCURRING_PCM_TAG
ON base.RECORD_KEY = rec.RECORD_KEY
WHERE
base.PCM_STATUS = 'ENROUTE'
AND rec.PCM_HRC_TAG IS NULL OR rec.PCM_HRC_TAG = ''
AND rec.PCM_EQP_TAG IS NULL OR rec.PCM_EQP_TAG = ''
The error occurs on base.PCM_TAG the 5th line in the SQL statement
Your from clause is not the typical way to write the joins. It is allowed, but this affects the scoping of the identifiers. Essentially, this is interpreted as:
from THB_View.PCM_PCM_BASE base left join
(THB_View.PCM_PCM_BASE_REOCCUR rec left join
THB_View.ATV atv
on base.PCM_TAG = atv.ATV_OCCURRING_PCM_TAG
)
on base.RECORD_KEY = rec.RECORD_KEY
Which explains why base is not recognized.
Just write the joins the standard way with the on condition right after the tables being joined:
from THB_View.PCM_PCM_BASE base left join
THB_View.PCM_PCM_BASE_REOCCUR rec
on base.RECORD_KEY = rec.RECORD_KEY left join
THB_View.ATV atv
on base.PCM_TAG = atv.ATV_OCCURRING_PCM_TAG

I can simply use a select statment on a join to pull results I'd Like using:
Select * from RESULTS (NOLOCK) left join orders on Results.ordno = orders.ordno
left join folders on folders.folderno = orders.folderno
left join pranaparms on folders.prodcode = pranaparms.prodcode and results.analyte = pranaparms.analyte
WHERE Results.s <> 'OOS-A' and Results.Final Between pranaparms.LOWERQCLIMIT and pranaparms.UPPERQCLIMIT and (pranaparms.LOWERQCLIMIT IS NOT NULL and pranaparms.UPPERQCLIMIT IS NOT NULL)
and results.ordno in (1277494)
However, is there a convenient way which I could do an update on the selected fields?
I have tried this so far:
Update RESULTS (NOLOCK) left join orders on Results.ordno = orders.ordno
left join folders on folders.folderno = orders.folderno
left join pranaparms on folders.prodcode = pranaparms.prodcode and results.analyte = pranaparms.analyte
set Results.S = 'OOS-B'
WHERE Results.s <> 'OOS-A' and Results.Final Between pranaparms.LOWERQCLIMIT and pranaparms.UPPERQCLIMIT and (pranaparms.LOWERQCLIMIT IS NOT NULL and pranaparms.UPPERQCLIMIT IS NOT NULL)
and results.ordno in (1277494)
However, it is passing an error indicating "Incorrect syntax near '('"
Is there a way for me to update off of this join or will I need to do tables individually?
Your select syntax suggests SQL Server. The correct update syntax in SQL Server is:
update r
set S = 'OOS-B'
from results r left join
orders o
on r.ordno = o.ordno left join
folders f
on f.folderno = o.folderno left join
pranaparms p
on f.prodcode = p.prodcode and r.analyte = p.analyte
where r.s <> 'OOS-A' and
r.Final Between p.LOWERQCLIMIT and p.UPPERQCLIMIT and
(p.LOWERQCLIMIT IS NOT NULL and p.UPPERQCLIMIT IS NOT NULL) and
r.ordno in (1277494);
Notes:
Table aliases make the query much easier to write and to read.
Do not use NOLOCK unless you know what you are doing. Given that you don't know the syntax rules for update for the database you are using, I will guess that you don't understand locks either.
Your WHERE conditions are turning the outer joins into inner joins. You should just specify the correct join type -- and probably move the conditions to the on clauses. I've left the logic as you wrote it.
I fix my problem by chance, but I really want to know why it works :),
Here's the thing:
I get the ORA-00933: SQL command not properly ended Error when I execute the following SQL statement:
INSERT INTO BASP_DX.QLR#GT(BDCDYH, QSZT)
SELECT NVL(e.BDCDYH, ' '),b.LIFECYCLE AS QSZT
FROM DJ_DY a
LEFT JOIN DJ_XGDJGL d
ON d.ZSLBH = a.SLBH
LEFT JOIN DJ_DJB e
ON e.SLBH = d.FSLBH
AND e.SLBH = '0123456789'
LEFT JOIN DJ_QLRGL f
ON f.SLBH = e.SLBH
AND f.QLRLX = 'Person1'
LEFT JOIN DJ_QLRGL b
ON b.SLBH = a.SLBH
AND (b.QLRLX = 'Person2' OR (b.QLRLX = 'Person3' AND b.QLRID = f.QLRID))
WHERE a.SLBH = '12345'
AND e.SLBH IS NOT NULL
-- add the condition to ensure that
-- this statement and the second statement get the same result
AND b.QLRID IS NOT NULL
AND (a.LIFECYCLE = '0' OR a.LIFECYCLE IS NULL);
I remove all the unnecessary insert value, related table and condition from the original SQL statement, to focus on the problem part.
Then I google it, from this post I know the causes may be:
An INSERT statement with an ORDER BY clause or an INNER JOIN
A DELETE statement with an INNER JOIN or ORDER BY clause
An UPDATE statement with an INNER JOIN
Apparently, these are not my type. I didn't use the INNER JOIN and ORDER BY, all I use is LEFT JOIN statement, so I wonder it might be reason that I set too many conditions with the LEFT JOIN statement (such as LEFT JOIN DJ_QLRGL b), so I try move the conditions after WHERE clause, it looks like this:
INSERT INTO BASP_DX.QLR#GT(BDCDYH, QSZT)
SELECT NVL(e.BDCDYH, ' '),b.LIFECYCLE AS QSZT
FROM DJ_DY a
LEFT JOIN DJ_XGDJGL d
ON d.ZSLBH = a.SLBH
LEFT JOIN DJ_DJB e
ON e.SLBH = d.FSLBH
AND e.SLBH = '0123456789'
LEFT JOIN DJ_QLRGL f
ON f.SLBH = e.SLBH
AND f.QLRLX = 'Person1'
LEFT JOIN DJ_QLRGL b
ON b.SLBH = a.SLBH
-- this conditions move to WHERE clause
WHERE a.SLBH = '12345'
AND e.SLBH IS NOT NULL
-- here is the original LEFT JOIN condition
AND (b.QLRLX = 'Person2' OR (b.QLRLX = 'Person3' AND b.QLRID = f.QLRID))
AND (a.LIFECYCLE = '0' OR a.LIFECYCLE IS NULL);
Then it works!
But why?
I just want to know the reason for this situation.
Solution
the problem is triangular join, the LEFT JOIN conditions can't contain the condition concerning both the self join table, in this case, it's b.QLRID = f.QLRID, so when I remove the b.QLRID = f.QLRID condition, it works.
Firstly, the join of "DJ_QLRGL b" is not LEFT any more,
as WHERE condition excludes rows with no b counterpart found
My current query show the data from the table called "Buque" and has some references from another tables. The problem is when i execute the query it never shows the result because it consumes too much memory i guess.
The current query i have
select buq.buq_codigo, tbu.tbu_codigo, tbu.tbu_nombre, pai.pai_codigo, pai.pai_nombre,
pue.pto_codigo, pue.pto_nombre, lin.lin_codigo, lin.lin_nombre, tra.tra_codigo,
tra.tra_nombre, buq.buq_nombre, buq.buq_des, buq.num_trb, buq.num_eslora,
buq.max_tons, buq.reg_lloyd, buq.buq_codigo1, buq.codigo_omi,
case buq.buq_estado when 'A' then 'Activo' else 'Inactivo' end as buq_estado
from publico.mae_buque as buq, publico.mae_tipbuque as tbu, publico.mae_pais as pai,
publico.mae_puerto as pue, publico.mae_linea as lin, publico.mae_trafico as tra
where buq.tbu_codigo = tbu.tbu_codigo or
buq.pai_codigo = pai.pai_codigo or
buq.pto_codigo = pue.pto_codigo or
buq.lin_codigo = lin.lin_codigo or
buq.tra_codigo = tra.tra_codigo
I also tried with inner joins but the problem is it returns me the data that meets the conditions of the joins. In other words, if the join has data to compare, returns the name, if not, show the null data.
The query must return me 611 records, with inner joins returns 68 records.
Concerning your desired result, use left outer joins, which fill up any non-existing rows of the right hand side table with null-values;
Concerning the out of memory issue, note that you used or to connect your tables; this actually leads to the fact that almost every record of the involved tables is connected to almost every other record (almost a cross join / cartesian product); This can get very large if you connect 6 tables...
select buq.buq_codigo, tbu.tbu_codigo, tbu.tbu_nombre, pai.pai_codigo, pai.pai_nombre,
pue.pto_codigo, pue.pto_nombre, lin.lin_codigo, lin.lin_nombre, tra.tra_codigo,
tra.tra_nombre, buq.buq_nombre, buq.buq_des, buq.num_trb, buq.num_eslora,
buq.max_tons, buq.reg_lloyd, buq.buq_codigo1, buq.codigo_omi,
case buq.buq_estado when 'A' then 'Activo' else 'Inactivo' end as buq_estado
from publico.mae_buque as buq
left outer join publico.mae_tipbuque as tbu on buq.tbu_codigo = tbu.tbu_codigo
left outer join publico.mae_pais as pai on (buq.pai_codigo = pai.pai_codigo)
left outer join publico.mae_puerto as pue on (buq.pto_codigo = pue.pto_codigo)
left outer join publico.mae_linea as lin on (buq.lin_codigo = lin.lin_codigo)
left outer join publico.mae_trafico as tra on (buq.tra_codigo = tra.tra_codigo)
You have to use left outer join:
select *
from
publico.mae_buque as buq
left outer join publico.mae_tipbuque as tbu on (buq.tbu_codigo = tbu.tbu_codigo)
left outer join publico.mae_pais as pai on (buq.pai_codigo = pai.pai_codigo)
left outer join publico.mae_puerto as pue on (buq.pto_codigo = pue.pto_codigo )
left outer join publico.mae_linea as lin on (buq.lin_codigo = lin.lin_codigo)
left outer join publico.mae_trafico as tra on (buq.tra_codigo = tra.tra_codigo);
I have encountered very strange behavior of my query and I wasted a lot of time to understand what causes it, in vane. So I am asking for your help.
SELECT count(*) FROM main_table
LEFT JOIN front_table ON front_table.pk = main_table.fk_front_table
LEFT JOIN info_table ON info_table.pk = front_table.fk_info_table
LEFT JOIN key_table ON key_table.pk = COALESCE(info_table.fk_key_table, front_table.fk_key_table_1, front_table.fk_key_table_2)
LEFT JOIN side_table ON side_table.fk_front_table = front_table.pk
WHERE side_table.pk = (SELECT MAX(pk) FROM side_table WHERE fk_front_table = front_table.pk)
OR side_table.pk IS NULL
Seems like a simple join query, with coalesce, I've used this technique before(not too many times) and it worked right.
In this query I don't ever get nulls for side_table.pk. If I remove coalesce or just don't use key_table, then the query returns rows with many null side_table.pk, but if I add coalesce join, I can't get those nulls.
It seems key_table and side_table don't have anything in common, but the result is so weird.
Also, when I don't use side_table and WHERE clause, the count(*) result with coalesce and without differs, but I can't see any pattern in rows missing, it seems random!
Real query:
SELECT ECHANGE.EXC_AUTO_KEY, STOCK_RESERVATIONS.STR_AUTO_KEY FROM EXCHANGE
LEFT JOIN WO_BOM ON WO_BOM.WOB_AUTO_KEY = EXCHANGE.WOB_AUTO_KEY
LEFT JOIN VIEW_WO_SUB ON VIEW_WO_SUB.WOO_AUTO_KEY = WO_BOM.WOO_AUTO_KEY
LEFT JOIN STOCK stock3 ON stock3.STM_AUTO_KEY = EXCHANGE.STM_AUTO_KEY
LEFT JOIN STOCK stock2 ON stock2.STM_AUTO_KEY = EXCHANGE.ORIG_STM
LEFT JOIN CONSIGNMENT_CODES con2 ON con2.CNC_AUTO_KEY = stock2.CNC_AUTO_KEY
LEFT JOIN CONSIGNMENT_CODES con3 ON con3.CNC_AUTO_KEY = stock3.CNC_AUTO_KEY
LEFT JOIN CI_UTL ON CI_UTL.CUT_AUTO_KEY = EXCHANGE.CUT_AUTO_KEY
LEFT JOIN PART_CONDITION_CODES pcc2 ON pcc2.PCC_AUTO_KEY = stock2.PCC_AUTO_KEY
LEFT JOIN PART_CONDITION_CODES pcc3 ON pcc3.PCC_AUTO_KEY = stock3.PCC_AUTO_KEY
LEFT JOIN STOCK_RESERVATIONS ON STOCK_RESERVATIONS.STM_AUTO_KEY = stock3.STM_AUTO_KEY
LEFT JOIN WAREHOUSE wh2 ON wh2.WHS_AUTO_KEY = stock2.WHS_ORIGINAL
LEFT JOIN SM_HISTORY ON (SM_HISTORY.STM_AUTO_KEY = EXCHANGE.ORIG_STM AND SM_HISTORY.WOB_REF = EXCHANGE.WOB_AUTO_KEY)
LEFT JOIN RC_DETAIL ON stock3.RCD_AUTO_KEY = RC_DETAIL.RCD_AUTO_KEY
LEFT JOIN RC_HEADER ON RC_HEADER.RCH_AUTO_KEY = RC_DETAIL.RCH_AUTO_KEY
LEFT JOIN WAREHOUSE wh3 ON wh3.WHS_AUTO_KEY = COALESCE(RC_DETAIL.WHS_AUTO_KEY, stock3.WHS_ORIGINAL, stock3.WHS_AUTO_KEY)
WHERE STOCK_RESERVATIONS.STR_AUTO_KEY = (SELECT MAX(STR_AUTO_KEY) FROM STOCK_RESERVATIONS WHERE STM_AUTO_KEY = stock3.STM_AUTO_KEY)
OR STOCK_RESERVATIONS.STR_AUTO_KEY IS NULL
Removing LEFT JOIN WAREHOUSE wh3 gives me about unique EXC_AUTO_KEY values with a lot of NULL STR_AUTO_KEY, while leaving this row removes all NULL STR_AUTO_KEY.
I recreated simple tables with numbers with the same structure and query works without any problems o.0
I have a feeling COALESCE is acting as a REQUIRED flag for the joined table, hence shooting the LEFT JOIN to become an INNER JOIN.
Try this:
SELECT COUNT(*)
FROM main_table
LEFT JOIN front_table ON front_table.pk = main_table.fk_front_table
LEFT JOIN info_table ON info_table.pk = front_table.fk_info_table
LEFT JOIN key_table ON key_table.pk = NVL(info_table.fk_key_table, NVL(front_table.fk_key_table_1, front_table.fk_key_table_2))
LEFT JOIN (SELECT fk_, MAX(pk) as pk FROM side_table GROUP BY fk_) st ON st.fk_ = front_table.pk
NVL might behave just the same though...
I undertood what was the problem (not entirely though): there is a LEFT JOIN VIEW_WO_SUB in original query, 3rd line. It causes this query to act in a weird way.
When I replaced the view with the other table which contained the information I needed, the query started returning right results.
Basically, with this view join, NVL, COALESCE or CASE join with combination of certain arguments did not work along with OR clause in WHERE subquery, all rest was fine. ALthough, I could get the query to work with this view join, by changing the order of joined tables, I had to place table participating in where subquery to the bottom.
I'm trying to pass this query to inner join, but it does not know how?
This is the query I want to use InnerJoin with these values where

Thank you!
I think you are trying to go to the standard (explicit) syntax. What you need to do is take what would be your JOIN operators in the WHERE clause and move them near the table itself. What you need to know is what tables on the left (Before the INNER JOIN operator you are joining to the right (After the INNER JOIN operator)
