DefaultValue for Property

Migrating from dotConnect for Oracle v7 and Entity FrameWork 4.0 to dotConnect for Oracle v8.3.135.6 and Entity Framework 6.1. Still using EntityObject template.

Here's an example of an existing table.

Code: Select all

CREATE
	TABLE "PL"."SYSTEMPARAMETRAR"
	(
		"GRUPP"          CHAR(16 BYTE) DEFAULT NULL,
		"LINJE"          CHAR(16 BYTE) DEFAULT NULL,
		"PARAMETER"      CHAR(20 BYTE) DEFAULT NULL NOT NULL ENABLE,
		"PARAMETER_DATA" CHAR(72 BYTE) DEFAULT ' ',
		"TYP"            CHAR(1 BYTE),
		"MAX_STORLEK"    NUMBER(*,0) DEFAULT 0,
		"MIN_STORLEK"    NUMBER(*,0) DEFAULT 0,
		"KOMMENTAR"      CHAR(50 BYTE) DEFAULT ' ',
		"SKP_DATUM" DATE DEFAULT sysdate,
		"SKP_TID" CHAR(8 BYTE) DEFAULT TO_CHAR(sysdate,'HH24:MI:SS'),
		"UPD_DATUM" DATE DEFAULT sysdate,
		"UPD_TID"             CHAR(8 BYTE) DEFAULT TO_CHAR(sysdate,'HH24:MI:SS'),
		"ANTAL_UPPDATERINGAR" NUMBER(*,0) DEFAULT 0,
		CONSTRAINT "SYSTEMPARAMETRAR_PRIM_KEY" PRIMARY KEY ("GRUPP", "LINJE", "PARAMETER") USING INDEX PCTFREE 10 INITRANS 2 MAXTRANS 255 COMPUTE STATISTICS STORAGE(INITIAL 65536 NEXT 1048576 MINEXTENTS 1 MAXEXTENTS 2147483645 PCTINCREASE 0 FREELISTS 1 FREELIST GROUPS 1 BUFFER_POOL DEFAULT) TABLESPACE "PLTSIDX" ENABLE,
		CHECK ( max_storlek         >= 0 ) ENABLE,
		CHECK ( min_storlek         >= 0 ) ENABLE,
		CHECK ( antal_uppdateringar >= 0 ) ENABLE
	)
	PCTFREE 10 PCTUSED 40 INITRANS 1 MAXTRANS 255 NOCOMPRESS LOGGING STORAGE

		INITIAL 131072 NEXT 1048576 MINEXTENTS 1 MAXEXTENTS 2147483645 PCTINCREASE 0 FREELISTS 1 FREELIST GROUPS 1 BUFFER_POOL DEFAULT
	)
	TABLESPACE "PLTS1" ;

Gives me this:

        #endregion
    }

And this:

Code: Select all

        <EntityType Name="SYSTEMPARAMETRAR">
          <Key>
            <PropertyRef Name="GRUPP" />
            <PropertyRef Name="LINJE" />
            <PropertyRef Name="PARAMETER" />
          </Key>
          <Property Name="GRUPP" Type="CHAR" Nullable="false" MaxLength="16" />
          <Property Name="LINJE" Type="CHAR" Nullable="false" MaxLength="16" />
          <Property Name="PARAMETER" Type="CHAR" Nullable="false" MaxLength="20" />
          <Property Name="PARAMETER_DATA" Type="CHAR" MaxLength="72" devart:DefaultValue="' '" DefaultValue=" " />
          <Property Name="TYP" Type="CHAR" MaxLength="1" />

          <Property Name="MIN_STORLEK" Type="decimal" Scale="0" DefaultValue="0" />

          <Property Name="UPD_TID" Type="CHAR" MaxLength="8" DefaultValue="to_char(sysdate,'HH24:MI:SS')" />
          <Property Name="ANTAL_UPPDATERINGAR" Type="decimal" Scale="0" DefaultValue="0" />
        </EntityType>

So when I run the code I get:

And the exception: {"ORA-12899: value too large for column \"PL\".\"SYSTEMPARAMETRAR\".\"SKP_TID\" (actual: 29, maximum: 8)"}

I get the text "to_char(sysdate, 'HH24:MI:SS')" instead of the result from the function.
This worked in EF4.0, have I missed something in my update?

Ok, so this http://blog.devart.com/set-identity-and ... faultvalue speaks about my problem.

If I manually change to this (directly in the code or in the (devart) entity developer) it works (almost, I can't set the value to anything myself, it always get the to_char-value):

Code: Select all

          <Property Name="SKP_TID" Type="CHAR" MaxLength="8" DefaultValue="to_char(sysdate,'HH24:MI:SS')" StoreGeneratedPattern="Computed" />
          <Property Name="UPD_TID" Type="CHAR" MaxLength="8" DefaultValue="to_char(sysdate,'HH24:MI:SS')" StoreGeneratedPattern="Computed" />

It works for the DATE-columns.

Patrik

I tried making the columns NOT NULLABLE but got the same result.

1. Please remove the DefaultValue and StoreGeneratedPattern attributes from the definitions of your SKP_TID and UPD_TID properties in both CSDL and SSDL parts of the model.

2. Turn on the InsertNullBehaviour.Omit option in your code before using the SYSTEMPARAMETRAR entity:

Code: Select all

    var config = Devart.Data.Oracle.Entity.Configuration.OracleEntityProviderConfig.Instance;
    config.DmlOptions.InsertNullBehaviour = Devart.Data.Oracle.Entity.Configuration.InsertNullBehaviour.Omit;

3. Check the SQL statement generated by Entity Framework:
http://www.devart.com/dotconnect/oracle ... nitor.html
http://www.devart.com/dbmonitor/dbmon3.exe

Does this help?

PatrikAhlquist · Post by **PatrikAhlquist** » Wed 23 Apr 2014 06:42

It does help, but every time I update the model (with the "Update From Database Wizard") all columns on all tables in my model get the 'DefaultValue="to_char(sysdate,'HH24:MI:SS')"' added right back.

Do I really have to do this manually every time?

Regards,
Patrik

Shalex · Post by **Shalex** » Fri 25 Apr 2014 12:41

The behaviour is changed in the new 8.3.146 build of dotConnect for Oracle: now a property in the generated code is initialized basing on the default value in CSDL only (instead of default values in any of SSDL and CSDL).

Update From Database Wizard compares SSDL part with database. So clear the value in the Default Value attribute in the CSDL part of your model to avoid initialization of the corresponding property in the code. Update From Database Wizard will not see this change and will not offer to update the property in the model.

Also be aware that Update From Database Wizard remembers the choice made once in the wizard. For example: you unchecked the change for a particular column, after this the corresponding change will be unchecked by default in the next runs of Update From Database Wizard.

Does this information help?

I tried something else (see the "default=select max...").

Code: Select all

            <PropertyRef Name="TLOP_NR" />
          </Key>
          <Property Name="TLOP_NR" Type="decimal" Nullable="false" StoreGeneratedPattern="Identity" devart:DefaultValue="(SELECT MAX(TLOP_NR)+1 FROM RH_SUMANALYS)" />

        </EntityType>
        <EntityType Name="RH_SUMANALYS_RESULTAT">
          <Key>

            <PropertyRef Name="SORT_ID" />
          </Key>
          <Property Name="TLOP_NR" Type="decimal" Nullable="false" />
          <Property Name="SORT_ID" Type="CHAR" Nullable="false" MaxLength="20" />
          <Property Name="PRIM_SORT" Type="CHAR" Nullable="false" MaxLength="20" devart:DefaultValue="'                    '" DefaultValue="                    " />
          <Property Name="SEC_SORT" Type="CHAR" MaxLength="20" devart:DefaultValue="'                    '" DefaultValue="                    " />
          <Property Name="TETR_SORT" Type="CHAR" MaxLength="20" devart:DefaultValue="'                    '" DefaultValue="                    " />

          <Property Name="UPD_DATUM" Type="DATE" Nullable="false" devart:DefaultValue="sysdate" />
          <Property Name="UPD_TID" Type="CHAR" Nullable="false" MaxLength="8" />
        </EntityType>

With the InsertDefaultOrOmit flag.

Code: Select all

            var config = Devart.Data.Oracle.Entity.Configuration.OracleEntityProviderConfig.Instance;
            config.DmlOptions.InsertNullBehaviour = Devart.Data.Oracle.Entity.Configuration.InsertNullBehaviour.InsertDefaultOrOmit;

And it almost worked! I got this back when I added a new RH_SUMANALYS with one child (RH_SUMANALYS_RESULTAT).

The changes to the database were committed successfully, but an error occurred while updating the object context. The ObjectContext might be in an inconsistent state. Inner exception message: The object state cannot be changed. This exception may result from one or more of the primary key properties being set to null. Non-Added objects cannot have null primary key values. See inner exception for details.

dbMonitor shows:

Code: Select all

DECLARE
  updatedRowid ROWID;
BEGIN
INSERT INTO PL.RH_SUMANALYS(TLOP_NR, MASKIN_NR, DYGNS_TYP, TIDS_TYP, TIDS_KOD, SORT_KVAL, SPEC_ID, MALKVALITET, NOMINELL_YTVIKT_MIN, NOMINELL_YTVIKT_MAX, GRUNDKVALITET, ANTAL_UPPDATERINGAR, UPD_DATUM)
VALUES ((SELECT MAX(TLOP_NR)+1 FROM RH_SUMANALYS), :p0, :p1, :p2, :p3, :p4, :p5, '      ', :p6, :p7, :p8, :p9, :p10)
RETURNING ROWID INTO updatedRowid;
OPEN :outParameter FOR SELECT TLOP_NR FROM PL.RH_SUMANALYS WHERE ROWID = updatedRowid;
END;

-- -1 row(s) affected.

and

INSERT INTO PL.RH_SUMANALYS_RESULTAT(TLOP_NR, PRIM_SORT, SEC_SORT, TETR_SORT, MAN_EDIT, VIKT, ANTAL, TID, ANTAL_UPPDATERINGAR, UPD_DATUM)
VALUES (:p0, :p1, :p2, '                    ', :p3, :p4, :p5, :p6, :p7, :p8)

p0 is 100212

But this should be possible, right?

Patrik

Have you initialized the SORT_ID property of the RH_SUMANALYS_RESULTAT object in your code?
If this doesn't help, please send us a small test project with the corresponding DDL/DML script so that we can reproduce the issue in our environment.

No, how (and to what value) should I do that?

For example: myRH_SUMANALYS_RESULTATObject.SORT_ID = "valid_value";

PatrikAhlquist wrote:to what value

Please set it to any valid value which is allowed by the design of your database.
