Multiple joins in SQL Server

Hi I have a requirement where in i haev to convert the SQL from Oracle
to the one which will run on the SQL server.

in the Oracle Query i am doing multiple joins, between some 13 tables.
and some of these joins are inner joins and some are Left outer joins.

table1 inner joined with table 2
table2 inner join with table3
table2 inner join with table4
table2 left join with table5
table5 left jin with table6
table6 left jin with table7
table7 left jin with table8
table8 left jin with table9

Any idea how to achieve this??

Easy peasy, e.g.

select <list of fields>
from table1
join table2 on table1.a = table2.a
join table3 on table2.b = table3.b
join table4 on table2.c = table4.c
left join table5 on table2.d = table5.d
left join table6 on table5.e = table6.e
left join table7 on table6.f = table7.f
left join table8 on table7.g = table8.g
left join table9 on table8.h = table9.h

Narendra,

Assuming on Oracle you don't face the deprecated (+) syntax it should be
identical since the JOIN syntax is SQL Standard. What fails?

Cheers

Hello All & Thanks in advance for your help! Background: 1) tblT_Documents is the primary parent transaction table that has 10 fields and about 250,000 rows 2) There are 9 child tables with each having 3 fields each, their own PK; the FK back to the parent table; and the unique data for that table. There is a one to many relation between the parent and each of the 9 child rows. Each child table has between 100,000 and 300,000

I have a SQL query I'm invoking via VB6 & ADO 2.8, that requires three "Left Outer Joins" in order to return every transaction for a specific set of criteria. Using three "Left Outer Joins" slows the system down considerably. I've tried creating a temp db, but I can't figure out how to execute two select commands. (It throws the exception "The column prefix 'tempdb' does not match with a table name or alias name used in the query.")

I was inspired by the recent discussion of returning multiple recordsets to ADO from a stored procedure. (Amazed is probably more accurate). I asked about how to accomplish same with Oracle and got a nudge in the right direction from Mr. Kreft. I promised to provide details once working, so here it is. The code is shown below. My next step is to build this technique into my application. I'm hoping for substantial performance gain. ...

I'm kind of comfortable with basic joins, but a current project requires a complex query of many tables. The GROUP_CONCAT(DISTINCT ...) function has been very useful as returning my values as comma delimited values when joining multiple tables. I have one table called 'floorplans' which has two fields (floorplan_jpg & floorplan_pdf), I'd like each of these fields to return arrays of the same length (they have the same # of values in the data...

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
