I'm using the following statement to determine the correct prefix:
select *
from [lcsCDR].[dbo].[Phones] c
inner join [CallAnalysisDatabase].[dbo].[CallRates$] r
on r.Prefix COLLATE Latin1_General_CI_AI = SUBSTRING(c.PhoneUri,1,LEN(r.Prefix))
left join [CallAnalysisDatabase].[dbo].[CallRates$] r_anti
on r_anti.Prefix COLLATE Latin1_General_CI_AI = SUBSTRING(c.PhoneUri,1,LEN(r_anti.Prefix))
and LEN(r_anti.Prefix) > LEN(r.Prefix)
where r_anti.Prefix is null
Could you please give me an example for adding a formula integrated within this statement?
The 'Rate' table contains 2 calculation fields:
start_rate
rate_per_minute
A tables 'VoipDetails' and SessionDetails contains the folowing:
DATEDIFF(s, VoipDetails.SessionIdTime, SessionDetails.SessionEndTime)
If the correct prefix is found THEN use the following formule:
DATEDIFF(s, VoipDetails.SessionIdTime, SessionDetails.SessionEndTime))/60)*r.rate_per_minute)+start_rate)
Could you please give me an example for pl/sql ms sql server management studio?
If I understand your question correctly then you want a Scalar Function in T-SQL.

I'm trying to select columns from two tables, Lignes and Détail Production. Détail Production links to the first one with the key NoLigne (which is the same name in both tables).
I know that I have to put [ ] or `` around the table's name, but I'm having the error No value given for one or more required parameters, which I believe means that SQL doesn't recognize the name. I tried aliasing the name of the table having a space in its name, but I have the same error. Here is my code:
SELECT
NoProduction,
Quantite,
DateMaxProd,
Lignes.Référence
FROM
[Détail Production] AS D
INNER JOIN
Lignes ON D.NoLigne = Lignes.NoLigne
WHERE
D.Soldee = 0 AND
D.EtatLigne = 0 AND
Lignes.Soldee = 0 AND
(QteRecue - Quantite - Acompter * NbHS)>0
Unfortunately, I can't get rid of the alias or the name of the table in the FROM and WHERE clause because my tables share columns with the same name. I can't rename the tables or the columns, and I'm actually using the software Windev which uses HFSQL as a dbms. I'm trying to connect to an access database with the OLEDB connector, and when I switch to HFSQL it works.
Here is a mre:
SELECT
*
FROM
[Détail Production]
INNER JOIN
Lignes ON [Détail Production].NoLigne = Lignes.NoLigne
When using HFSQL database, it works, when using OLEDB with an access database, it throws the error No value given for one or more required parameter
Thanks for your help.
I found the problem:
SELECT
D.NoProduction,
D.Quantite,
D.DateMaxProd,
Lignes.Référence
FROM
[Détail Production] AS D
INNER JOIN
Lignes ON D.NoLigne = Lignes.NoLigne
WHERE
D.Soldee = 0 AND
D.EtatLigne = 0 AND
Lignes.Soldee = 0 AND
(D.QteRecue - D.Quantite - D.Acompter * D.NbHS) > 0
I was missing the comparison on the last condition of the WHERE clause. I thought it was because of the alias or the brackets because others online had similar problems and the error changed as I tried other ways of writing the FROM clause. The right way to write a name with spaces in HFSQL is with brackets [ ]. Also, there were problems with names not matching accents from the database.
I'm using Access ADP as a front end to SQL. I have two tables:
One is Price_2018
One is Price_2020
I want to choose Price from the Price_2018 or the Price_2020 table, depending upon the Purchase_Date. I tried first putting IiF statement in the Query Designer:
Iif ([Purchase_Date] < Convert(DateTime, '2020-01-01 00:00:00'),[Price_2018],[Price_2020])
Access didn't allow that and ended up putting the whole thing in quotes in the SQL pane, so all I got was text output.
Someone suggested putting in the Select section:
CASE ([Purchase_Date] < CONVERT(DATETIME, '2020-01-01 00:00:00') WHEN 1 THEN [Price_2018] ELSE [Price_2020]
That didn't work either and gave me this error:
Error in list of function arguments: '<' not recognized.Error in list of function arguments: ',' not recognized.Error in list of function arguments: 'FROM' not recognized.
Unable to parse query text.
How to resolve this error. I'm not familiar with using a CASE statement in Access or SQL.
I combined 2 Price tables (combined table called VWC_2018_2020) as suggested. Full query:

What now? Thanks
Since ADP files use an SQL Server backend (no longer supported as of MS Access 2013), you must use its TSQL dialect which does support IIF (or CASE) and can compare dates with string representations without conversion.
Below I extend to fuller query assuming various columns. Adjust as needed:
SELECT
...
IIF(t.[Purchase_Date] < '2020-01-01', p18.price, p20.price)
...
FROM [Transactions] t
INNER JOIN [Price_2018] p18
ON t.price_id = p18.price_id
INNER JOIN [Price_2020] p20
ON t.price_id = p20.price_id
I have the following SQL statement which returns the desired result in SQL Server 2012:
SELECT
S.ONOMA
, S.DIEY
, S.POLH
, S.TK
, S.IDIOT
, S.KODIKOS
, S.AFM
FROM
SYNERG AS S
INNER JOIN
(SELECT
G.AFM, MIN(KODIKOS) AS KODIKOS
FROM SYNERG AS G
WHERE LEN(ISNULL(AFM, '')) != 0
GROUP BY AFM) AS I ON S.KODIKOS = I.KODIKOS
ORDER BY
S.AFM
but when I run the same SQL statement in MS Access 2007 I get an error:
Circular reference caused by 'KODIKOS' in query definition's SELECT list.
Any help would be appreciated.
As explained in the link by HansUp:
The alias of a calculated field cannot be identical to any of the field names used to calculate the field.
This can be rather annoying (esp. if it is a field that is returned by the query), but there is no way around it.
So you need to change the alias, e.g.:
SELECT
S.ONOMA
, S.DIEY
, S.POLH
, S.TK
, S.IDIOT
, S.KODIKOS
, S.AFM
FROM
SYNERG AS S
INNER JOIN
(SELECT
G.AFM, MIN(KODIKOS) AS MinKODIKOS
FROM SYNERG AS G
WHERE LEN(Nz(AFM, '')) <> 0
GROUP BY AFM) AS I ON S.KODIKOS = I.MinKODIKOS
ORDER BY
S.AFM
Note also that an IsNull() function exists in Access, but has a different meaning (it takes one argument and returns a Boolean). The corresponding function is Nz()
And (thanks #HansUp), the unequal operator is <>, not !=. I always use <> in SQL Server too, no need to make things more complicated than necessary. :)
I have a table that contains a column storing sql functions, column names and similar snippets such as below:
ID | Columsql
1 | c.clientname
2 | CONVERT(VARCHAR(10),c.DOB,103)
The reason for this is to use selected rows to dynamically create results from the main query that match spreadsheet templates. EG Template 1 requires the above client name and DOB.
My Subquery is:
select columnsql from CSVColumns cc
left join Templatecolumns ct on cc.id = ct.CSVColumnId
where ct.TemplateId = 1
order by ct.columnposition
The results of this query are 2 rows of text:
c.clientname
CONVERT(VARCHAR(10),c.DOB,103)
I would wish to pass these into my main statement so it would read initially
Select(
select columnsql from CSVColumns cc
left join Templatecolumns ct on cc.id = ct.CSVColumnId
where ct.TemplateId = 1
order by ct.columnposition
) from Clients c
but perform:
select c.clientname, CONVERT(VARCHAR(10),c.DOB,103) from clients c
to present a results set of client names and DOBs.
So far my attempts at 'injecting' are fruitless. Any suggestions?
You can't do this, at least not directly. What you have to do is, in a stored procedure, build up a varchar/string containing a complete SQL statement; you can execute that string.
declare #convCommand varchar(50);
-- some sql to get 'convert(varchar(10), c.DOB, 103) into #convCommand.
declare #fullSql varchar(1000);
#fullSql = 'select c.clientname, ' + #convCommand + ' from c,ients c;';
exec #fullSql
However, that's not the most efficient way to run it - and when you already know what fragment you need to put into it, why don't you just write the statement?
I think the reason you can't do that is that SQL Injection is a dangerous thing. (If you don't know why please do some research!) Having got a dangerous string into a table - e.g 'c.dob from clients c;drop table clients;'- using the column that contains the data to actually execute code would not be a good thing!
EDIT 1:
The original programmer is likely using a C# function:
string newSql = string.format("select c.clientname, {0} from clients c", "convert...");
Basic format is:
string.format("hhh {0} ggg{1}.....{n}, s0, s1,....sn);
{0} in the first string is replaced by the string at s0; {1} is replaces by tge string at s1, .... {n} by the string at sn.
This is probably a reasonable way to do it, though why is needs all the fragments is a bit opaque. You can't duplicate that in sql, save by doing what I suggest above. (SQL doesn't have anything like the same string.format function.)
In Oracle 11g, I came across an error for a query and cannot figure why it is erroring on me. Here is the query:

) main_data
Selecting individual fields like above will give me an "invalid identifier error". If I do select * then it gives me back the data without any error. What am I doing wrong here? Thank you.
The old quoted identifier problem... see point 9 in the database object naming documentation, and note that Oracle does not recommend using quoted identifiers.
You've put your column alias as lower case inside double-quotes. That means that any references to it also have to be quoted and exactly match the case. So this would work:
select
main_data.issue_number,
main_data."transaction_number"
from
...
But unless you have a burning need to have that alias like that - and I doubt you do as all the identifier names from the actual table columns are not quoted - it would be simpler to remove the double quotes from the inner selects:
select
main_data.issue_number,
main_data.transaction_number
from
(
select
...
'' as transaction_number,
p1header.check_account_number
...
UNION ALL
select
...
'' as output_tx_number_prin,
'' as output_tx_number_int,
check.transaction_number,
check.dda_number as check_account_number
...
You don't actually need to alias the columns in the second branch of the union; the column identifiers will all be taken from the first branch.
