TQuery Float field is implicitly rounded to integer when using ODBC - oracle

I'm querying 1 value from table. In db it's value is 48.8
When my app use BDE's native Oracle SQL Link driver, everything is Ok, it's still 48.8.
Then I make the app to use another BDE alias, which use ODBC data source (latest driver from Oracle). And now displayed value is 48.0
Details
The column is factW NUMBER(10, 3).
Test code:
var
q: TQuery;
begin
q := TQuery.Create( SELF );
try
q.DatabaseName := 'Realize';
q.SQL.Text := 'SELECT factW, TO_CHAR(factW) charW'
+'FROM bSertific WHERE id_sertific = :id';
q.ParamByName('id').AsInteger := dm1.Sertif1ID_SERTIFIC.AsInteger;
q.Open;
ShowMessage( ' factW = '
+ FloatToStrF(
q.FieldByName('factW').AsFloat,
ffFixed,
5, 3 ) // here 48.000
+ ' charW = ' + q.FieldByName('charW').AsString // here 48.8
);
finally
q.Free;
end;
end;


I hadn't find a proper solution. The workaround is to query the field as a string and convert it back and forth on the client side.

ODP.NET, Managed reading LONG column results in ORA-01009

I'm trying to get the source of a view in my .net app.
To do this, I query DBA_VIEWS: it has a column TEXT with exactly what I need. The type is LONG.
If I do it using the Unmanaged driver, everything works as expected.
The same code with Managed driver results in ORA-01009: missing mandatory parameter.
Adding a transaction around the command and using breakpoint and "slow" steps sometimes results in the same code working.
ODP.NET version is 19, Oracle DB is 18c Express Edition. Strangely enough, the same code works just fine with Oracle Database 12c regardless of driver type.
Is there maybe some setting I need to change on the database or in code? I'm completely lost here.
Code I'm using for testing:
Imports System.Data.Common
Imports Oracle.ManagedDataAccess
'Imports Oracle.DataAccess
Module Views
Function CreateCommand(Connection As DbConnection) As System.Data.Common.DbCommand
Dim cmd As Data.Common.DbCommand = Connection.CreateCommand()
With CType(cmd, Client.OracleCommand)
.BindByName = True
.FetchSize = &H100000 '1 Mb
.InitialLONGFetchSize = -1 'the entire LONG or LONG RAW data is prefetched and stored in the fetch array.
.InitialLOBFetchSize = -1 'the entire LOB data is prefetched and stored in the fetch array.
End With
Return cmd
End Function
Sub query()
Try
Using DBConnection = New Client.OracleConnection("User ID=TESTUSER;Password=TESTPWD;Data Source=TESTDB;Pooling=True")
DBConnection.Open()
Using DBConnection.BeginTransaction()
Using cmdSQL = CType(CreateCommand(DBConnection), Client.OracleCommand)
cmdSQL.CommandText = "select TEXT from DBA_VIEWS where VIEW_NAME = :0"
Dim p = cmdSQL.CreateParameter()
p.ParameterName = "0"
p.Value = "TEST_VIEW"
cmdSQL.Parameters.Add(p)
Dim sw = Stopwatch.StartNew
Using rdr = cmdSQL.ExecuteReader
rdr.FetchSize = 2 ^ 20
While rdr.Read
Dim row(rdr.FieldCount - 1) As Object
rdr.GetProviderSpecificValues(row)
Dim x = row(0)
Console.WriteLine($"{x.ToString.Length} bytes")
End While
End Using
Console.WriteLine($"{sw.ElapsedMilliseconds} ms")
End Using
End Using
End Using
Catch ex As Exception
Console.WriteLine(ex.ToString)
End Try
End Sub
End Module

You can use an anonymous block with output parameter and a call to ExecuteNonQuery. Your command text will be
"begin select TEXT into :0 from DBA_VIEWS where VIEW_NAME = :1; end;"
Add 2 parameters. Make sure that
' Parameter #1 has
p.Direction = ParameterDirection.Output
p.OracleDbType = OracleDbType.Long
p.Size = 1000000
And use command cmd.ExecuteNonQuery(). Then, when parameter is retrieved, just use its value
Dim txt As String = cmd.Parametersp[0].Value.ToString()

It's a pity, Oracle deprecated LONG data type for ages but LONG data is still used many times for internal data.
You could write a function and then get the data by calling the function:
create or replace function GetViewText(v in varchar2) return clob is
ret CLOB;
BEGIN
FOR aRow IN (SELECT TEXT FROM DBA_VIEWS WHERE VIEW_NAME = v) LOOP
ret := aRow.TEXT;
-- or ret := TO_CLOB(aRow.TEXT);
END LOOP;
RETURN ret;
END;

Yet another way from this answer is to (ab)use dbms_xmlgen.getxml.
We can either use it to query a single view's code (as in my original question)
with input as (
select
:0 as VIEW_NAME
from dual
)
SELECT
substr(
text_xml,
instr(text_xml, '<LONGCOL>') + length('<LONGCOL>'),
instr(text_xml, '</LONGCOL>', -1) - (instr(text_xml, '<LONGCOL>') + length('<LONGCOL>'))
) as TEXT
from
(
-- getxml can return malformed xml (which is good in this case)
-- while getxmltype can not.
select dbms_xmlgen.getxml(q'{
SELECT TEXT as LONGCOL
FROM SYS.DBA_VIEWS
WHERE VIEW_NAME = '}' || input.VIEW_NAME || q'{'
}') as text_xml
from input
)
or create our own DBA_VIEWS version.
create or replace view APP_SCHEMA.DBA_VIEWS
as
select
OWNER, VIEW_NAME, TEXT_LENGTH,
case
when (TEXT_VC is not null and TEXT_LENGTH <= 4000)
then to_clob(TEXT_VC)
when TEXT is NULL
then NULL
else (
SELECT
substr(
text_xml,
instr(text_xml, '<LONGCOL>') + length('<LONGCOL>'),
--instr(text_xml, '</LONGCOL>', -1) - (instr(text_xml, '<LONGCOL>') + length('<LONGCOL>'))
TEXT_LENGTH
) as TEXT
from
(
-- getxml can return malformed xml (which is good in this case)
-- while getxmltype can not.
select dbms_xmlgen.getxml(q'{
SELECT TEXT as LONGCOL
FROM SYS.DBA_VIEWS
WHERE OWNER = '}' || OWNER || q'{'
and VIEW_NAME = '}' || VIEW_NAME || q'{'
}') as text_xml
from dual
)
)
end as TEXT,
TEXT_VC, TYPE_TEXT_LENGTH, TYPE_TEXT, OID_TEXT_LENGTH, OID_TEXT, VIEW_TYPE_OWNER, VIEW_TYPE, SUPERVIEW_NAME, EDITIONING_VIEW, READ_ONLY, CONTAINER_DATA, BEQUEATH, ORIGIN_CON_ID, DEFAULT_COLLATION, CONTAINERS_DEFAULT, CONTAINER_MAP, EXTENDED_DATA_LINK, EXTENDED_DATA_LINK_MAP, HAS_SENSITIVE_COLUMN

Oracle Spatial : SDO_RELATE returns Polygon that are not inside

I am having an issue with the SDO_RELATE, it is returning the geometries that
are not inside
t.geom is not inside of myGeom() but it is still returning 8 results.
Does anyone have any idea?
The query:
select t.geom from GEOM_TABLE t where SDO_RELATE(t.geom, MDSYS.ST_GEOMETRY( mygeom() ).geom,'mask=INSIDE')= 'TRUE';
the table GEOM_TABLE has 8 GEOM:

CT_FETCH error in PowerBuilder Program

Save yourself a ton of headaches and use datawindows... You'd reduce that entire script to about 10 lines of code.

Paul Horan gave you good advice. This would be simple using DataWindows or DataStores. Terry Voth is on the right track for your problem.
In your code, Variable l_pvds_obj_id needs to be the same type as gx_l_doc_obj_id because if you get a result, it will always be equal to it. From the apparent naming scheme it was intended to be long. This is the kind of stuff we look for in peer reviews.
A few other things:
Most of the time you want SQLCode not SQLDbCode but you didn't say what database you're using.
After you UPDATE crt_script you need to check the result.
I don't see COMMIT or ROLLBACK. Autocommit isn't suitable when you need to update multiple tables.
You aren't using most of the values from the first SELECT. Perhaps you've simplified your code for posting or troubleshooting.

Fixing sql length error in progress 4gl 10.2B

I'm trying to use the openedge jdbc connector to pull data from an existing progress db but im running into column width issues.
Here is the error that is holding me up.
[DataDirect][OpenEdge JDBC Driver][OpenEdge] Column TabDisplayName in table PUB.Menu has value exceeding its max length or precision.
I've looked at many posts, each offering different advice, and here's what I've given a go this far:
Manually modify the SQL width via the data dictionary.
I ran a quick check on PUB.Menu.TabDisplayName to find a max value of 44 Characters
Set the width to x(50) to no avail and then x(100) out of a fix of irrational rage, again with no luck.
Use the SUBSTR() SQL Function to truncate the field -not optimum but better than nothing
I get weird results with this. It works fine in sqlexp but in a java environment its like the column is never selected.
Use the dbtool to automatically fix width problems with option #2
After selecting all tables and "areas" (not sure what those are...) and submitting the final option I am returned to the proenv cmdline as if nothing ever happened.
Modify the sql width programmatically via 4gl
This is the only option I found that I have yet to try.
I am a little reluctant to try this only because a manual modification failed. Also this is a live development environment(for me only) and Im trying to mess it up too terribly, although i am taking snaps regularly.
Running progress 10.2B on a unix machine.
Any comments and suggestions would be appreciated.
-Thanks

The dbtool option is the best. It is designed for this. From proenv you should see something like this:
proenv> dbtool s2k

If your db has a server up & running choose "1" at the connect: prompt. If not, choose "0".
Pick 100 for padding to double the width of fields.
Try it on a copy of the "sports" database if you are unsure. Use a higher level of verboseness if you want some insight into what it is doing.
It does not take very long to run on a small development database. (It is basically instantaneous on "sports".)

It is possible to create views with substring (field.name,1,maxlength) option and use PUB2.viewname instead pub.tablename

Passing huge XML from C#/.Net to Oracle Stored Procedure via CLOB parameter - ORA-01008: not all variables bound

Environment:
Server: Oracle 11.2g server on a 64-bit windows 2008
Client: Oracle 11g client on Windows XP SP3, ASP.Net 4.0, Visual Studio 2010, C#
Input size of XML ~ 1,206,500 characters (Calculated based on the maximum data that I would have).
Scenario:
The web application generates the XML that the oracle stored procedure uses to update a table in the database. Since the XML size is pretty large, the Stored Procedure Parameter type chosen is CLOB instead of LONG as LONG has a limitation of 32760 characters.
Problem:
Using CLOB as the parameter type throws up the error "ORA-01008: not all variables bound" for the same stored procedure code which works perfectly for the parameter type as LONG (and XML length < 32760)
C# Code for invoking stored procedure:
OracleCommand DbUpdateCommand = null;
OracleLob tempLOB = null;
DbUpdateCommand.CommandText = "declare xx clob; begin dbms_lob.createtemporary(xx, false, 0); :tempclob := xx; end;";
DbUpdateCommand.Parameters.Add(new OracleParameter("tempclob", OracleType.Clob)).Direction = ParameterDirection.Output;
DbUpdateCommand.ExecuteNonQuery();
//Assign the value to the LOB
tempLOB = (OracleLob)DbUpdateCommand.Parameters[0].Value;
tempLOB.BeginBatch(OracleLobOpenMode.ReadWrite);
//Convert the string to byte array to write to LOB
UnicodeEncoding encoding = new UnicodeEncoding();
byte[] renewalDetailXMLBytes = encoding.GetBytes(renewalDetailXML);
tempLOB.Write(renewalDetailXMLBytes, 0, renewalDetailXMLBytes.Length);
tempLOB.EndBatch();
DbUpdateCommand.CommandText = "P_WEB_PRDCR_RNEW_UPDT";
DbUpdateCommand.CommandType = System.Data.CommandType.StoredProcedure;
DbUpdateCommand.Parameters.Add("PN_KEY_AGNT_RNEW_HDR",
System.Data.OracleClient.OracleType.Number, 12).Value = agentRenewalHeader;
DbUpdateCommand.Parameters.Add("PN_KEY_CO",
System.Data.OracleClient.OracleType.Number, 12).Value = companyCode;
DbUpdateCommand.Parameters.Add("PC_RNWL_DETL_XML",
System.Data.OracleClient.OracleType.Clob).Value = tempLOB;
DbUpdateCommand.Parameters.Add("PS_USR_NM",
System.Data.OracleClient.OracleType.VarChar,255).Value = userName;
DbUpdateCommand.ExecuteNonQuery();
Oracle Stored Procedure Code:
CREATE OR REPLACE PROCEDURE DOIADMIN.P_WEB_PRDCR_RNEW_UPDT (
PN_KEY_AGNT_RNEW_HDR IN NUMBER,
PN_KEY_CO IN NUMBER,
PC_RNWL_DETL_XML IN CLOB,
PS_USR_NM IN VARCHAR2
)
AS
lx_rnew_detl_xml XMLTYPE;
lct_rnew_detl_cntx DBMS_XMLSAVE.ctxtype;
--Construct the complete xml for financial data
lx_rnew_detl_xml := XMLTYPE(PC_RNWL_DETL_XML);
--table to be updated with the xml
lct_rnew_detl_cntx := DBMS_XMLSAVE.newcontext('IL_AGNT_RNEW_DETL');
--Set the key column list
DBMS_XMLSAVE.SETKEYCOLUMN(lct_rnew_detl_cntx, 'KEY_AGNT_RNEW_HDR');
DBMS_XMLSAVE.SETKEYCOLUMN(lct_rnew_detl_cntx, 'KEY_CO');
DBMS_XMLSAVE.SETKEYCOLUMN(lct_rnew_detl_cntx, 'KEY_INDVDL_LIC');
--Set the udpate column
DBMS_XMLSAVE.SETUPDATECOLUMN(lct_rnew_detl_cntx, 'FLG_MARKED_FOR_CANCEL');
--update the table from the rows
ln_cntr := DBMS_XMLSAVE.UPDATEXML(lct_rnew_detl_cntx, lx_rnew_detl_xml.getCLOBVal());
DBMS_XMLSAVE.closecontext(lct_rnew_detl_cntx);
END p_web_prdcr_rnew_updt;
Anyone who has worked with passing large XML via CLOB parameter and converted that CLOB to XML in the stored procedure can please help? Any alternate approach to this problem would also be highly appreciated.
Thanks in advance.

Here is the C# code that fixed the issue. I was missing to clear the parameters before reusing the same command object.
C# Code
OracleCommand DbUpdateCommand = null;
OracleLob tempLOB = null;
DbUpdateCommand.CommandText = "declare xx clob; begin dbms_lob.createtemporary(xx, false, 0); :tempclob := xx; end;";
DbUpdateCommand.Parameters.Add(new OracleParameter("tempclob", OracleType.Clob)).Direction = ParameterDirection.Output;
DbUpdateCommand.ExecuteNonQuery();
//Assign the value to the LOB
tempLOB = (OracleLob)DbUpdateCommand.Parameters[0].Value;
tempLOB.BeginBatch(OracleLobOpenMode.ReadWrite);
//Convert the string to byte array to write to LOB
UnicodeEncoding encoding = new UnicodeEncoding();
byte[] renewalDetailXMLBytes = encoding.GetBytes(renewalDetailXML);
tempLOB.Write(renewalDetailXMLBytes, 0, renewalDetailXMLBytes.Length);
tempLOB.EndBatch();
DbUpdateCommand.CommandText = "P_WEB_PRDCR_RNEW_UPDT";
DbUpdateCommand.CommandType = System.Data.CommandType.StoredProcedure;
//Missing line - start
DbUpdateCommand.Parameters.Clear();
//Missing line - end
DbUpdateCommand.Parameters.Add("PN_KEY_AGNT_RNEW_HDR",
System.Data.OracleClient.OracleType.Number, 12).Value =
agentRenewalHeader;
DbUpdateCommand.Parameters.Add("PN_KEY_CO",
System.Data.OracleClient.OracleType.Number, 12).Value =
companyCode;
DbUpdateCommand.Parameters.Add("PC_RNWL_DETL_XML",
System.Data.OracleClient.OracleType.Clob).Value =
tempLOB;
DbUpdateCommand.Parameters.Add("PS_USR_NM",
System.Data.OracleClient.OracleType.VarChar,255).Value =
userName;
DbUpdateCommand.ExecuteNonQuery();
