Actually, it's not. I'm using the Firebird's default parameter syntax,
the question mark. And, I use "new object[] {paramValue1, paramValue2,
etc..}" to pass the parameters, and paramValueX are just simple
variables or object properties, don't have to be FbParameter. I don't
remember trying @p0, although I did try with actual names(i.e.:
@PDate), since it was also documented in the MSDN documentation, but I
was getting an invalid field error coming from Firebird.
But, as you mentioned, one might have to look at the EF6 sources to
find out the real behavior.

Well, AFAIK only the @p0 is supported. Maybe the {0} works as well, but
I know only about the @p0 from documentation. Of course we can check EF6
sources, but I'm too lazy to do that. :D

Re: [Firebird-net-provider] EF handling - as string parameter
Hello Jiri,
its my fault: AUSLASTUNG_GEHOERT_ZU is Varchar(20), the parameter "Halle 6 -
Schlosserei" is 21 chars long After correcting the length to 30 it works
fine. Interessting the slq console does not compain about the too long input
for the query.
Thanks for answering to my posting that fast.
Can you please add 1 line to describe the difference between using {0} vs. @p0
?
Thanks
Niko

Re: [Firebird-net-provider] EF handling - as string parameter
Hello Jiri,
thanks for the response.
I guess I am missing something here. The code below produces the same error as
{0}.
ppaQuery = "SELECT * FROM LPP_PRODUKTIONSAUFTRAEGE WHERE PRODUKTIONSSTATUS NOT
IN ('Abgeschlossen','Storno') AND AUSLASTUNG_GEHOERT_ZU = @p0 ORDER BY
PRODUKTIONSAUFTRAG_ID";
tmpPPA = this._ctx.LPP_PRODUKTIONSAUFTRAEGE.SqlQuery(ppaQuery, new
object[]{this.CurrentHalle}).ToList();
If I copy the query to the SQL tool and execute the query it works fine (even
when it does not return a record, which is also the case in other working
queries).
SELECT * FROM LPP_PRODUKTIONSAUFTRAEGE WHERE PRODUKTIONSSTATUS NOT IN
('Abgeschlossen','Storno') AND AUSLASTUNG_GEHOERT_ZU = 'Halle 6 - Schlosserei'
ORDER BY PRODUKTIONSAUFTRAG_ID
Do you have an idea whats missing?
Thanks
Niko

Hi,
I just saw that the query and the execution do not match correct. This is the
query with the parameter that creates an exception if the parameter is "Halle 6

ppaQuery = "SELECT * FROM LPP_PRODUKTIONSAUFTRAEGE WHERE PRODUKTIONSSTATUS NOT

[Firebird-net-provider] EF handling - as string parameter
Hello,
I am using following query to get all workitems for a specific organisation
unit:
ppaQuery = "SELECT * FROM LPP_PRODUKTIONSAUFTRAEGE WHERE PRODUKTIONSSTATUS
NOT IN ('Abgeschlossen','Storno') ORDER BY PRODUKTIONSAUFTRAG_ID";
tmpPPA = this._ctx.LPP_PRODUKTIONSAUFTRAEGE.SqlQuery(ppaQuery).ToList();
This works fine, unless the parameter contains a -. In this case I receive
an exception "arithmetic exception, numeric overflow, or string
truncation\r\nstring right truncation"
In the case I concatenate the sql query it works fine:
ppaQuery = "SELECT * FROM LPP_PRODUKTIONSAUFTRAEGE WHERE PRODUKTIONSSTATUS
NOT IN ('Abgeschlossen','Storno') AND AUSLASTUNG_GEHOERT_ZU = '" +
this.CurrentHalle + "' ORDER BY PRODUKTIONSAUFTRAG_ID";
tmpPPA = this._ctx.LPP_PRODUKTIONSAUFTRAEGE.SqlQuery(ppaQuery,
this.CurrentHalle).ToList();
Its EF 6.13 and Firebird .net Provider 4.10 (I am aware of the newer
versions but need to migration a big number of assemblies).
I would like to understand if there is a way to resolve this problem in a
more elegant way.
Thanks
Niko
