Output Array Binding

I am looking for an example of output array binding (equivalent to BULK COLLECT). The input sample code is very good, but the documentation talks about output binding as well, but there are no examples.
If anyone has a short example that shows how to set up the bind variables, I would very much appreciate it.

Hi,
From
http://download-west.oracle.com/docs/cd/B19306_01/win.102/b14307/featOraCommand.htm#BABBDHBB
<snippet>
// execute the cmd
cmd.ExecuteNonQuery();
//print out the parameter's values
Console.WriteLine("parameter values after executing the PL/SQL block");
for (int i = 0; i < 3; i++)
Console.WriteLine("Param2[{0}] = {1} ", i,
(cmd.Parameters[1].Value as Array).GetValue(i));
for (int i = 0; i < 3; i++)
Console.WriteLine("Param3[{0}] = {1} ", i,
(cmd.Parameters[2].Value as Array).GetValue(i));

Exception Handling for Array Binding

Hi
1)
I am using a Stored Procedure.
I am using array binding and if i am sending an array of count 10 to be inserted in a table and only 9 got inserted,i deliberatly inserted one errorneous record in array, the count returned by ExecuteNonQuery() is 10.Why ?
How can i come to know exact number of rows inserted in table, how can i use Output variables, because the array bind count is 10 so if i add an output parameter it gives error ArrayBind count is wrong....
2)
Is it possible to roll back all the inserts if error occurs in any of the insert by Oracle engine.What it does is it inserts all correct records and leaves the errorneous record and doesn't even throw any exception or any message.
Answer - This can be achieved by using OracleTransaction and don't use Exception handling in procedure otherwise there wont be any exception thrown by procedure which is necessary to detect if an error occured during insert.If you use exception handling OracleEngine will insert correct rows and leave errorneous record and return count of inserted + non inserted records which is wrong.
Please help.

You'll need to encapsulate your validation within it's own block as described below:
-- this will die on the first exception
declare
TYPE T_BADDATA_TEST IS TABLE OF VARCHAR2(1000) INDEX BY binary_integer ;
tbt T_BADDATA_TEST ;
aBadTypeFound exception ;
begin
   tbt(0) := 'a';
   tbt(1) := 'b';
   tbt(2) := 'c';
    for idx in tbt.first..tbt.last loop
      if tbt(idx) = 'b' then
          raise aBadTypeFound ;
      else
          dbms_output.put_line(tbt(idx));
      end if ;
    end loop ;
end ;--encapsulate the exception area in a begin/end block to handle the exception but continue on
declare
TYPE T_BADDATA_TEST IS TABLE OF VARCHAR2(1000) INDEX BY binary_integer ;
tbt T_BADDATA_TEST ;
aBadTypeFound exception ;
begin
   tbt(0) := 'a';
   tbt(1) := 'b';
   tbt(2) := 'c';
    for idx in tbt.first..tbt.last loop
      BEGIN
      if tbt(idx) = 'b' then
          raise aBadTypeFound ;
      else
          dbms_output.put_line(tbt(idx));
      end if ;
      EXCEPTION
        WHEN aBadTypeFound THEN
            dbms_output.put_line(tbt(idx) || ' is bad data');
        WHEN OTHERS THEN
            dbms_output.put_line('exception');
      END ;
    end loop ;
end ;

Reg: PLS-00418: array bind type must match PL/SQL table row type error

I am trying to access a table of records through JDBC OracleCallableStatement. I am able to do it fine for all mappings except for the ones below
TYPE CAT_CD_TYPE IS TABLE OF A.B %TYPE INDEX BY BINARY_INTEGER;
TYPE ORG_CD_TYPE IS TABLE OF C.D %TYPE INDEX BY BINARY_INTEGER;
Column B is CHAR(1) and Column D is CHAR(2). I am trying to register the out parameters of Oraclecallablestatement as
cstmt.registerIndexTableOutParameter(2, 2000, OracleTypes.CHAR, 0);
cstmt.registerIndexTableOutParameter(3, 2000, OracleTypes.CHAR, 0);
All the other mappings work fine. These two fail with the error
SQLException in invokeDBPackage() : ORA-06550: line 1, column 32:
PLS-00418: array bind type must match PL/SQL table row type
ORA-06550: line 1, column 35:
PLS-00418: array bind type must match PL/SQL table row type
ORA-06550: line 1, column 7:

I tried other OracleTypes mappings too but no luck so far.
Any advice on this would be greatly appreciated.

PLS-00418: array bind type must match PL/SQL table row type

If a PL/SQL table is indexed by CHAR and is a parameter
in a Stored Program, we are not able to call the stored
program from the Java code.
We get the following error code.
java.sql.SQLException: ORA-06550: line 1, column 62:
PLS-00418: array bind type must match PL/SQL table row type
ORA-06550: line 1, column 7:

But if we change the CHAR into VARCHAR2 then it works.
We are using Oracle9i Enterprise Edition Release 9.2.0.5.0 -64bit Production ,
JServer Release 9.2.0.5.0 - Production
and JDK1.4.

Array Bind: nbr of updated rows?

Hello,
when using array binding with UPDATE statements, how to look up the number of updated rows?
I couldn't find any parameter property such as ArrayBindAffectedRows.
Is it possible to use array bind with SQL statements which return values, e.g.:
UPDATE emp SET salary = salary + :increase
WHERE mgr = :mgrNo
RETURNING salary INTO :newSalary;
Hm, arrays :increase and :newSalary might have different lengths.
Thanks,
Armin

Ok this is genuinly tricky.
The only way I can think of to get this is to use FORALL and BULK COLLECT. This does an array-bound insert from PL/SQL. But you need to pass Associative Arrays from ODP.NET to PL/SQL to get this started.
Any other solution I could think of would require running some PL/SQL code for each update statement, for instance in a trigger. But avoiding the context switches from PL/SQL to SQL is a main reason to use array binding in the first place.
Here's a complete sample program:
I used inline PL/SQL for compactness, but you might want to save the block as a procedure.
using System;
using System.Data;
using Oracle.DataAccess.Client;
using Oracle.DataAccess.Types;
     public class Test
      static OracleConnection connect()
        string constr = "data source=oracle;user id=scott;password=tiger";
        OracleConnection con = new OracleConnection(constr);
        con.Open();
        return con;
    const string sql = @"
declare

    update emp
    SET
    sal = sal + l_increase(idx)
    WHERE mgr = l_managers(idx)
    RETURNING sal BULK COLLECT INTO l_newSals;
:records_affected := l_newSals.count;
end;

Associative array binding - poor performance

Dear All
i have very very low performence when i am inserting a binary array using associative array bind. i mean when i insert huge jagged binary array.
the jagged array has
BinarryArray[0][0]........BinarryArray[0][8000]
BinarryArray[1][0]........BinarryArray[1][8000]
BinarryArray[3600][0]........BinarryArray[3600][8000]
BinarryArray[0] - i have 8000 byte end so on. total is 3600 X 8000
that means 28,800KB hence to ~28MB.
the C# code is as follows
string strInsert "Insert Into T Values(t.SEQUENCE.currval, :paramArr);
OracleCommand objCommand = new OracleCommand;
OracleParameter objParam = new OracleParameter(paramArr, OracleDbtype.blob, 8000, system.data.ParameterDirection.Input,true,0,0,"ColumnName", system.data.DataRowVersion.Curren, BinarryArray);
objCommandtext = strInsert;
objCommand.ArrayBindCount = BinarryArray.Length;
objCommand.Parameters.Clear();
objCommand.Parameters.Add(paramArr);
objCommand.ExecuteNonQuery();
In generall the Insertion is good for each row in the array i get separate row in the DB but it works so slow.
why??????
see the code below

well??

User Defined Type - Array bind Query very slow

Hi.
I have following Problem. I try to use Oracle Instant Client 11 and ODP.NET to pass Arrays in SELECT statements as Bind Parameters. I did it, but it runs very-very slow. Example:
- Inittial Query:
SELECT tbl1.field1, tbl1.field2, tbl2.field1, tbl2.field2 ... FROM tbl1
LEFT JOIN tbl2 ON tbl1.field11=tbl2.field0
LEFT JOIN tbl3 ON tbl2.field11=tbl3.field0 AND tbll1.field5=tbl3.field1
...and another LEFT JOINS
WHERE
tbl1.field0 IN ('id01', 'id02', 'id03'...)
this query with 100 elements in "IN" on my database takes 3 seconds.
- Query with Array bind:
in Oracle I did UDT: create or replace type myschema.mytype as table of varchar2(1000)
than, as described in Oracle Example I did few classes (Factory and implementing IOracleCustomType) and use it in Query,
instead of IN ('id01', 'id02', 'id03'...) I have tbl1.field0 IN (select column_value from table(:prmTable)), and :prmTable is bound array.
this query takes 190 seconds!!! Why? I works, but the HDD of Oracle server works very hard, and it takes too long.
Oracle server we habe 10g.
PS: I tried to use only 5 elements in array - the same result, it takes also 190 seconds...
Please help!

I recommend you generate an explain plan for each query and post them here. Based on what you have given the following MAY be happening:
Your first query has as static IN list when it is submitted to the server. Therefore when Oracle generates the execution plan the CBO can accurately determine it based on a KNOWN set of input parameters. However the second query has a bind variable for this list of parameters and Oracle has no way of knowing at the time the execution plan is generated what that list contains. If it does not know what the list contains it cannot generate the most optimal execution plan. Therefore I would guess that it is probably doing some sort of full table scan (although these aren't always bad, remember that!).
Again please post the execution plans for each.
HTH!

Support for Array Binding and PL/SQL tables (IN, INOUT, or OUT)

I have attempted, unsuccessfully, to use array binding in stored procedure/function calls where the sp/sf has parameters that are PL/SQL tables. I have seen the topic floating around in this forum, but I have not seen the explicit questions:
- Does ODP.NET support PL/SQL tables as IN, INOUT or OUT parameters to stored procedures/functions?
- Will any planned ODP.NET release support PL/SQL tables as IN, INOUT or OUT parameters to stored procedures/functions?
I am aware that I can use REF CURSORS to handle the OUT situation, but I need to make a design decision concerning supporting parameters of IN and INOUT PL/SQL tables.
Thanks.
James

You really MUST do this!! - i.e. include support for PL/SQL table parameters (IN INOUT and OUT) in a future release of ODP.NET.
PL/SQL tables are a fundamental type in Oracle stored procedures and you will be preventing a huge number of existing projects from migrating to .NET if you don't acknowledge them as part and parcel of Oracle programming.
I sincerely hope support for PL/SQL table parameters is treated as a serious issue.
Think what a coup it would be for you over Microsoft (who don't currently support PL/SQL tables with their .NET native provider for Oracle and don't look as if they will at least in the short term)!
Please, please, please!

Using array binding to perform multiple rowupdates in one pass

For the first time I am attempting to use array binding in VB.NET to update multiple rows via a single execution of a stored procedure. My subroutine is:
Friend Sub UpdateSolutionStatusUsingArrays(ByVal intNumBeingUpdated As Integer, ByVal arrScenarioID() As Integer, ByVal arrSolutionID() As Integer, ByVal arrInOrOut() As Integer, ByVal arrTimePeriod() As Integer)
Try
'Set up the Command object
Dim cmdUpdateSolutionStatus As OracleCommand
cmdUpdateSolutionStatus = New OracleCommand
cmdUpdateSolutionStatus.CommandType = CommandType.StoredProcedure
cmdUpdateSolutionStatus.CommandText = "ProcUpdateSolutionStatus"
cmdUpdateSolutionStatus.Connection = cnnORACLE
cmdUpdateSolutionStatus.ArrayBindCount = intNumBeingUpdated - 1
cmdUpdateSolutionStatus.CommandTimeout = CInt(tblOptions.Rows(intDatabaseIndex).Item("ConnectionTimeout"))
'Add ScenarioID array as parameter
Dim p_ScenarioID As New OracleParameter("ScenarioID", OracleDbType.Int32)
p_ScenarioID.Direction = ParameterDirection.Input
p_ScenarioID.Value = arrScenarioID
cmdUpdateSolutionStatus.Parameters.Add(p_ScenarioID)
'Add SolutionID array as parameter
Dim p_SolutionID As New OracleParameter("SolutionID", OracleDbType.Int32)
p_SolutionID.Direction = ParameterDirection.Input
p_SolutionID.Value = arrSolutionID
cmdUpdateSolutionStatus.Parameters.Add(p_SolutionID)
'Add InOrOut array as parameter
Dim p_InOrOut As New OracleParameter("InOrOut", OracleDbType.Int32)
p_InOrOut.Direction = ParameterDirection.Input
p_InOrOut.Value = arrInOrOut
cmdUpdateSolutionStatus.Parameters.Add(p_InOrOut)
'Add TimePeriod array as parameter
Dim p_TimePeriod As New OracleParameter("TimePeriod", OracleDbType.Int32)
p_TimePeriod.Direction = ParameterDirection.Input
p_TimePeriod.Value = arrTimePeriod
cmdUpdateSolutionStatus.Parameters.Add(p_TimePeriod)
'Open connection
cnnORACLE.Open()
'Run stored procedure
cmdUpdateSolutionStatus.ExecuteNonQuery()
'Tidy up
cmdUpdateSolutionStatus = Nothing
cnnORACLE.Close()
Catch ex As Exception
WriteLog("Subroutine UpdateSolutionStatusUsingArrays:" & ex.Message.ToString)
strState = "Error"
'Update Run Status to show error has occurred
cnnORACLE.Close()
UpdateRunStatusORACLE(7)
End Try
End Sub
When the routine tries to run cmdUpdateSolutionStatus.ExecuteNonQuery() I get the error message:
Unable to cast object of type 'System.Int32[]' to type 'System.IConvertible'.
I have tried all sorts of variants of the code but with no success. The arrays are being set up correctly. Anyoneone know what I'm missing?

Try declaring the arrays as OracleNumber datatype instead of Integer. I've had this issue before, and I believe this is what I did to solve the problem.

Insert SDO_GEOMETRY using array binding

Hi,
does anyone know howto insert the elem_info array and the ordinates array of a SDO_GEOMETRY object using array binding and ODP or if there is a way to insert the SDO_GEOMETRY object using the same technique.
/Anders

The current releases of ODP.NET do not support object types, hence no "proper" SDO_GEOMETRY support. You can retrieve the data as an XML-type as illustrated here:
Re: ODP.Net + Spatial
I know of no way to insert an SDO_GEOMETRY object using array binding at this time.
If someone else has a solution, please do post!

Procedure Array Binding a Null Value

Can you perform array binding in ODP.NET (to a procedure for example that inserts values) and assume that if there are null values in the array that the records inserted will have the corresponding null values in their records?

Can I use Array Binding with a ExecuteDataSet or ExecuteReader methods?

I want to use Array binding with selects. From the examples that I see so far it seems like everyone is showing the ExecuteNonQuery method. I wonder if I can use this functionality with a regular query that returns ref cursoros.

what is the error you recieve?

How to loop an output array and pass each index to the next VI in the sequence in TestSTAND?

Hi,
I have 2 VIs - XX and YY. The output of XX generates an array of strings.
The input of YY takes in a string. I have VIs XX followed by YY in the
sequence editor.
For each item in the output array of XX, I want to pass that item into
YY and execute YY.
How do I do this in TestStand without creating an intermediate VI.
Your help is greatly appreciated folks!
Thx

Hi,
What you could do is set the second step to loop.
Then use as one of the parameters to VI YY the string array using RunState.LoopIndex as the array index.
eg. Locals.MyStringArray[RunState.LoopIndex]
Hope this helps

PL/SQL array bind output variable

I've been trying to learn how to pass an array to an pl/sql script. Getting the data into the db seems to be working fine, but I would like to know if there was a problem inserting the data. More specifically, I would like to know THE SPECIFIC ROW that caused the problem.
pl/sql code:
create or replace procedure pp (
          v_out      out number,
          v_listtype in repair_codes.listtype%type,
v_repaircode in repair_codes.repaircode%type
is
begin
insert into repair_codes (listtype, repaircode) values (v_listtype,v_repaircode);
     v_out:=1;
commit;
     --just setting up test variable for now
end;
vb.code:
Dim cmd As New OracleCommand("pp", dbConn)
cmd.CommandType = CommandType.StoredProcedure
cmd.ArrayBindCount = 3
Dim al(2) As String
Dim ar(2) As String
al(0) = "JOE1"
al(1) = "JOE2"
al(2) = "JOE3"
ar(0) = "TEST1"
ar(1) = "TEST2"
ar(2) = "TEST3456789"
Dim out As New OracleParameter("v_out", OracleDbType.Varchar2, 20)
out.Direction = ParameterDirection.Output
cmd.Parameters.Add(out)
Dim listtype As New OracleParameter("v_listtype", OracleDbType.Varchar2)
listtype.Value = al
cmd.Parameters.Add(listtype)
Dim repaircode As New OracleParameter("v_repaircode", OracleDbType.Varchar2)
repaircode.Value = ar
cmd.Parameters.Add(repaircode)
dbConn.Open()
Try
cmd.ExecuteNonQuery()
Catch ex As OracleException ' catches only Oracle errors
ex = ex
Select Case ex.Number
Case 1
MessageBox.Show("Error attempting to insert duplicate data.")
Case 12545
MessageBox.Show("The database is unavailable.")
Case Else
MessageBox.Show("Database error: " & ex.Message.ToString())
Dim wha = ex.Errors(0).ArrayBindIndex 'always '0'
End Select
Finally
dbConn.Close()
End Try
error:
OracleParameter.ArrayBindSize is invalid
Code above will work if I remove everything about the 'output' variable
To test I would like to put in data for a column that is too large, have all other rows inserted, but return the row that had bad data. Thanks for any thoughts on this-

I have a similar issue, i.e. the pl/sql table type as out parameter is causing probleml in one API related to Oracle Applications. I have singled this problem out by creating wrappers and testing them against BPEL process. Now as soon as I put an out parameter with pl/sql table in my wrapper, I start getting errors. Why the invoke even care about what is in output while calling the API? How can I get rid of it. I am not able to pin point where exactly you made the changes. Could you please share some more info or possibly share the BAD and GOOD code.
We will probably get away with this by creating just a wrapper that would have NO out parameter as PL/SQL table as I don't think we need it anyway.
Still want to know what is the issue here as we would like to avoid any custom wrapper creation?
