Is there a way to use positional parameters when calling Oracle stored procedure using System.Data.OracleClient?
IDataParameter parameter = dbCommand.CreateParameter( );
parameter.Value = "Blah Blah";
parameter.Type = OracleType.Varchar;
dbCommand.Parameters.Add(parameter);
The code above creates a parameter and assigns "Parameter1" name to it. When stored proc is called Oracle gives "wrong number or types of arguments" error.
Solved problem by switching to provider from Oracle (Oracle.DataAccess)

I have the below code which uses a method. When I try to assign the Field Symbol value [Type ANY] to the return parameter RO_TAB [Type Ref to Data], I am getting an error message OBJECTS_MOVE_NOT SUPPORTED [Conversion of type "l" to type "g" not supported.].
The issue is happening after a BW system upgrade along with which we also moved to ABAP objects. The code executes perfectly in the older version of ABAP.
The dump occurs in the below line:
RO_TAB = <lf_storage>.
I have no idea why.
method GET_LU_STORAGE_FOR_ODS.
* IMPORTS
* IF_ODS TYPE RSODSTECH
* IF_ODS_TABLE_TYPE TYPE ZODS_TAB_TYPE
* RETURNS
* RO_TAB TYPE REF TO DATA
FIELD-SYMBOLS:
<lf_storage> TYPE ANY.
DATA:
lf_index TYPE SY-TABIX,
lf_sindex TYPE STRING,
lf_name TYPE STRING.
lf_index = GET_LU_STORAGE_INDEX(
IF_ODS = IF_ODS
IF_ODS_TABLE_TYPE = IF_ODS_TABLE_TYPE ).
lf_sindex = lf_index.
CONCATENATE
'MO_LU_DATA_'
lf_sindex
INTO lf_name.
ASSIGN lf_name TO <lf_storage>.
RO_TAB = <lf_storage>.
endmethod.
You need to create a data object first, using the CREATE DATA statement. Then you can ASSIGN a field symbol to work with the dynamically created data object. There's an example in the online manual. A field symbol is not a reference, it simply places the variable assigned to it in its position. You're effectively trying to move a string (which is what lf_name is) to a reference variable, and that won't work.
You cannot assign a variable of type STRING to a variable of type REF TO DATA.
The following code snippet shows how it should be done.
DATA: lf_name TYPE string.
DATA: lo_tab TYPE REF TO DATA.
FIELD-SYMBOLS: <lf_name> TYPE string.
lf_name = 'test'.
GET REFERENCE OF lf_name INTO lo_tab.
*lf_name = lo_tab. "this is not allowed
ASSIGN lo_tab->* TO <lf_name>.
So in your case it would be sufficient to define a field symbol.
FIELD-SYMBOLS: <lf_name> TYPE STRING.
then assign the contents referenced by RO_TAB to this field symbol.
ASSIGN ro_tab->* TO <lf_name>.
and finally do the concatenation.
CONCATENATE
'MO_LU_DATA_'
lf_index
INTO <lf_name>.
That's all! No further assignments should be required.
How about just this?
lf_sindex = lf_index.
CONCATENATE
'MO_LU_DATA_'
lf_sindex
INTO RO_TAB.
Does anyone know how to pass a local variable to PlatonScript procedure as an argument?
I just don't want to use global variables.
Thanks
When you create a procedure that has parameters you have to declare it like
<p_targetsData>
<![CDATA[START:p_targetsData(testvar1,testvar2)
testvar1 = "test"
testvar2 = 123
RETURN 1 ]]>
</p_targetsData>
when you want to call it and pass the parameters you write
#testvar1:STRING
#testvar2:INTEGER
CALL p_targetsData(testvar1,testvar2)
jPlaton uses calling by reference so after the CALL execution your variables will still have their real value
In JMeter I added the configuration for oracle server. Then I added a JDBC request object and put the ResultSet variable name to status.
The test executes fine and result is displayed in treeview listener.
I want to use the variable status and compare it with string but jmeter is throwing error about casting arraylist to string.
How to retrieve this variable and compare with string in While Controller?
Just used some time to figure this out and think the accepted answer is slightly incorrect as the JDBC request sampler has two types of result variables.
The ones you specify in the Variable names box map to individual columns returned by your query and these you can access by saying columnVariable_{index}.
The one you specify in the Result variable name contains the entire result set and in practice this is a list of maps to values. The above syntax will obviously not work in this case.
The ResultSet variable returned with JDBC request in JMeter are in the for of array. So if you want to use variable status, you will have to use it with index. If you want to use the first(or only) record user status_1. So you need to use it like status_{index}.
String host = vars.getObject("status").get(0).get("option_value");
print(host);
log.info("----- " + host);
Form complete infromation read the "yellow box" in this link:
http://jmeter.apache.org/usermanual/component_reference.html#JDBC_Request
Other util example:
http://jmeter.apache.org/usermanual/build-db-test-plan.html
You can use Beanshell/Groovy (same code works) in JSR233 PostProcessor to work with “Result Variable Name” from JDBC Request like this:
ArrayList results = vars.getObject("status");
for (HashMap row: results){
Iterator it = row.entrySet().iterator();
while (it.hasNext()){
Map.Entry pair = (Map.Entry)it.next();
log.info(pair.getKey() + "=" + pair.getValue());
}
}
Instead of output to log replace with adding to string with delimiters of your choice.
I've got a function in an oracle database. I need to call it from delphi. I use the following code:
procedure TForm1.Run;
var
q:TADOQuery;
begin
q:=TADOQuery.Create(nil);
q.Connection:=ADOConnection1;
q.ParamCheck:=false;
q.SQL.Add('BEGIN');
q.SQL.Add(' :RES:=Search(:P_DATE);');
q.SQL.Add('END;');
q.Parameters.AddParameter.Name:='P_DATE';
q.Parameters.ParamByName('P_DATE').Direction:=pdInput;
q.Parameters.ParamByName('P_DATE').DataType:=ftDate;
q.Parameters.ParamByName('P_DATE').Value:=Now;
q.Parameters.AddParameter.Name:='RES';
q.Parameters.ParamByName('RES').DataType:=ftFloat;
q.Parameters.ParamByName('RES').Direction:=pdOutput;
q.Parameters.ParamByName('RES').Value:=1;
q.ExecSQL;
//...
I get ora-06550 error, saying invalid number or type of parameters. If I change the P_DATE parameter to sysdate, i.e. :RES:=Search(sysdate);, it works fine.
So how can I pass an "in" parameter of type DATE to an oracle function from delphi?
Found ORA-06550 when Oracle stored function is called.. However this relates to Kylix Pascal IDE. Am I expected to meet the same behaviour for delphi? Didn't try to use oracle procedure instead of a function. Maybe this issue can be solved some how else...
Oracle doesn't have a date type for bind variables - you need to explicitly convert the bind variable to a date:
:res := search(to_date(:p_date, 'dd/mm/yyyy'));
You should then be able to pass your variable as a string matching the date format you've specified.
Try to send this parameter as a string:
.........
q.SQL.Add('BEGIN');
q.SQL.Add(' :RES:=Search(TO_DATE(:P_DATE,''YYYYMMDD''));');
q.SQL.Add('END;');
q.Parameters.AddParameter.Name:='P_DATE';
q.Parameters.ParamByName('P_DATE').Direction:=pdInput;
q.Parameters.ParamByName('P_DATE').DataType:=ftString;
q.Parameters.ParamByName('P_DATE').Value:=FormatDateTime('yyyymmdd',Now);
..........
You're doing it wrong (and I think you had a previous question deleted as being a duplicate that asked this same question (different function, but same idea) just a couple of days ago).
You're calling the function wrong in the first place.
.........
q.SQL.Add('BEGIN');
q.SQL.Add(' SELECT Search(TO_DATE(:P_DATE,''YYYYMMDD'')) FROM System.Dual;');
q.SQL.Add('END;');
q.Parameters.AddParameter.Name:='P_DATE';
q.Parameters.ParamByName('P_DATE').Direction:=pdInput;
q.Parameters.ParamByName('P_DATE').DataType:=ftDate;
q.Parameters.ParamByName('P_DATE').Value:=Now;
q.Open;
if not q.IsEmpty then // or not q.Eof
Res := q.Fields[0].AsFloat;
I'm calling a system stored procedure for full text search package. It generates terms used for full text search based on a sql literal.
ex: exec ctx_query.explain('index_name', 'full text filter', 'explain table') etc
I'm doing the following in my code:
using(OracleCommand command = new OracleCommand("ctx_query.explain", DataAccess.GetConnString()))
{
comm.Parameters.AddWithValue("index_name", "explain1");
//comm.Parameters.AddWithValue("text_query", "(test) OR (term1 ACCUM term2");
comm.Parameters.AddWithValue("text_query", txtUserInput.Text);
comm.Parameters.AddWithValue("explain_table", "explain_results");
comm.Parameters.AddWithValue("sharelevel", 0);
comm.Parameters.AddWithValue("explain_id", new Guid().ToString().Substring(0,30));
comm.ExecuteNonQuery();
}
The "text_query" parameter will be built from user input. Does the above prevent sql injection because the textUserInput.Text will be passed as a command parameter?
ctx_query.explain does not execute the query, it only examines it, so there is no SQL injection risk here.
