Hi,

im trying to use a custom update function defined in SSDL part (see here).

It seems like the dataprovider is removing the quotes from the CommandText and lower casing it. When using

Code: Select all

<CommandText>UPDATE "TestTable" SET "TestColumn" = @TestColumn WHERE "TestTableID" = @TestTableID;</CommandText>

an exception is thrown that column testcolumn does not exist.

Is there any option to prevent this behaviour?

Thanks,
Dresel

I solved this issue. Coming from a MSSQL background, i missunderstood devart ef parameter mapping.

When using "@" for a parameter, you also have to add it to the parametername - otherwise it is (silently?) removed and treated as a column - thats why i thought the error is about the column and not about the parameter...

So with "@" as prefix possible solutions would be

Code: Select all

<CommandText>UPDATE "TestTable" SET "TestColumn" = @TestColumn WHERE "TestTableID" = @TestTableID;</CommandText>
<Parameter Name="@TestColumn" Type="int" Mode="In" />
<Parameter Name="@TestTableID" Type="int" Mode="In" />

or with ":" as prefix

Code: Select all

<CommandText>UPDATE "TestTable" SET "TestColumn" = :TestColumn WHERE "TestTableID" = :TestTableID;</CommandText>
<Parameter Name="TestColumn" Type="int" Mode="In" />
<Parameter Name="TestTableID" Type="int" Mode="In" />

Thanks,
Dresel
