I have to convert a DB2 query to SQL Server, but don't understand what exactly below query does:
SELECT
t.MyColumnA NAME(MyColumnA-01),
t.MyColumnA COLHDG("COA" "VALUE")
FROM
MyTable t
It looks like the NAME and COLHDG functions are just UI functions specific to HelpSystems. The actual query would be
SELECT t.MyColumnA AS "COA VALUE"
FROM MyTable t

In MS Access, I created a query by create Menu-> Query Design (with name Query3).
I want use it in an SQL command in another query but when I run it got this error:
Syntax error on query expression 'select f1'
SQL command
INSERT INTO boors (boors.Nemad, boors.Volumn, boors.Price,
boors.LastPrice, boors.LastPerc, boors.LastPr,
boors.LastPer, boors.MinPrice, boors.MaxPrice,
boors.distance, boors.inout, boors.Power)
values (select f1,f2,f3,f4,f5,f6,f7,f8,f9,f10,f11,f12 FROM Query3)
It appears that you are mixing the SQL used for inserting values and inserting from a table/query. As you are doing the latter, your SQL should look like:
INSERT INTO boors (Nemad, Volumn)
SELECT F1, F2
FROM Query3
Regards,
I linked an Oracle Database to my SQL Server in Microsoft SQL Server Management Studio 18. Server Objects -> Linked Servers.
I have a SQL Statement that when I run on the Oracle Developer Tool/Platform it returns the information as expected. But when I run the exact same query on the SQL Server it returns the incorrect results (The actual values in the rows and columns do not match).
What I know.
The table I am query in lives in the Oracle Database.
I can get the same/matching results on the Oracle Developer and SQL Server if I exclude in my WHERE statement anything involving a DATE.
Any thoughts?
The example of the query below.
Works on Oracle Developer but not on MSSQL
SELECT * FROM TABLE1
WHERE status = 'Deviation' and trunc(SRC_ROW_UPDT) BETWEEN TO_DATE('01/03/2020', 'DD/MM/YYYY') AND TO_DATE('10/12/2020','DD/MM/YYYY');
The example of the query below.
Works on both Oracle Developer and MSSQL
SELECT * FROM TABLE1
WHERE status = 'Deviation' and BATCHID = 'ThisBAtchID';
You cannot use ORACLE specific functions like TO_DATE in SQL Server calls. You have to execute them remotely using OPENQUERY. OPENQUERY in MSDN
SELECT * FROM OPENQUERY (OracleSvr, 'SELECT * FROM TABLE1
WHERE status = ''Deviation'' and trunc(SRC_ROW_UPDT) BETWEEN TO_DATE(''01/03/2020'', ''DD/MM/YYYY'') AND TO_DATE(''10/12/2020'',''DD/MM/YYYY'');');
I have rows which contains HTML tags. e.g.
<b>Abc</b> <strong>Bca</strong>
So I need to cut it out. As I suggest I need to find something like '%<%>%' and make a REPLACE to ''.
How can I do it? Interested for both solutions - MS SQL & Oracle also.
Assuming table is called yourtable and field is called htmltag.
In SQL Server:
SELECT
SUBSTRING(substring(htmltag,charindex('>',htmltag)+1,250),0,CHARINDEX('<',
substring(htmltag,charindex('>',htmltag)+1 ,250),0))
FROM yourtable
SQL FIDDLE
In Oracle
SELECT regexp_replace(htmltag, '<[^>]+>', '') htmltag
FROM yourtable
SQL FIDDLE
I need a common select statement that returns a fixed value / row without the need of tables, which has to work with both Oracle & Sql Server.
eg for Oracle I know I can use:
select 'O' AS INDICATOR from DUAL;
But this won't work on Sql Server.
Can this be done with the same SQL on both Oracle & SQL Server?
AFAIK, you'll need different queries, unless you can find a table that exists both on the SQL Server and on the Oracle Server.
Oracle uses the DUAL table for dummy queries, while the syntax to just select a constant on SQL server is a bit simpler:
select 'O' as Indicator
will return a one-row recordset.
P.S. If you intend to write just standard SQL and have it work on both SQL Server and Oracle, note that there are lots and lots of differences, even if you do not use database-side code (stored procedures and functions).
Off the top of my head, some things that are different:
Case statement syntax
NVL vs IsNull
Null sorting behaviour
Data conversion functions
String manipulation functions
etc, etc.
You can't select data in Oracle without from statement. So you need to have a table in Oracle (common practice is to use standard table - Dual). The best solution if you really need to run same query on both database servers is to create Dual table with only one row in MS SQL. But really it's better to use different queries for different servers (maybe via some abstraction layer).
Use a common table expression (CTE) e.g.
WITH D (INDICATOR)
AS
(
SELECT *
FROM (
VALUES ('O')
) T (c1)
)
SELECT INDICATOR
FROM D;
Or more simply in line:
SELECT *
FROM (
VALUES ('O')
) D (INDICATOR)
You can create the DUAL table in SQL Server:
CREATE TABLE DUAL (DUMMY NVARCHAR(1) NOT NULL);
INSERT INTO DUAL VALUES ('X');
and then use the same query as in Oracle:
select 'O' AS INDICATOR from DUAL;
I am trying to use the vs2008 query builder to create a query with a parameter.
I know that in sql server it would work with:
select col1,col2
from tbl
where col3=#myParam
How would it be typed in oracle or is it pl/sql?
I get the problem in the #myParam part.
Oracle SQL parameters are specified using :
SELECT col1, col2 FROM tbl WHERE col3=:myParam
You will have to be careful when specifying this as an OracleParameter though, as some libraries miss off the :, and some require it to bind correctly.
