You always pass failure on the way to success.

Hi all,
Table schema
empid primary key
emp_name
emp_age
emp_skills
emp_Isactive
I am storing multiple skills of a customer in same column separated with commas.I have designed a search form where in the employer enters skills in search box separated using commas. I want to match these skills irrespective of commas.
for this purpose i used a stored proc and passed skills as parameters
select skill from tbljob where skill like '%'+ISNULL(@skill1,skill)+'%' or skill like '%'+ISNULL(@skill2,skill)+'%' or skill like '%'+ISNULL(@skill3,skill)+'%'
but if one of the skill 1,2,3 is null ie if user enters only 1 or 2 , it returns all rows because the other condition is always true .
How can i use "OR" with other statements so that it works out

change your ISNULL() NULL result to something that can't be located:
ISNULL(@skill1,'&^%$')

Hi im executing a sql command from my C# windows form.
Its a count command : SELECT [COLUMN NAME], COUNT(*) FROM [DATABASE] GROUP BY [COLUMN].
2 Columns load from the results, the column name, and the number of records (count).
How can i display these results in a C# windows form? Datagrid, large textbox?
Please help me on this.

You can display them pretty much whichever way you want. What are the requirements? Grid seems like a good idea to me.

Hi,
How to convert .csv file .mdb file?
I am working in PL/SQL (toad) and C#
Here is my sample code:
string strConn = "Data Source=;User ID=; Password=;";
OracleConnection conn = new OracleConnection(strConn);
conn.Open();
OracleCommand cmd = new OracleCommand();
string strSQL;
strSQL = "";
strSQL += "INSERT INTO [MY_TBL] (";
strSQL += "F_NAME, ";
strSQL += "L_NAME) VALUES ( ";
strSQL += "SELECT ";
strSQL += "F_NAME, ";
strSQL += "L_NAME ";
strSQL += "FROM ";
strSQL += @"[Text;DATABASE=C:\myPath;]";
strSQL += ".";
strSQL += "[poc.csv])";
cmd = new OracleCommand(strSQL,conn);
cmd.ExecuteNonQuery();
conn.Close();
I am getting the error: invalid table name.
If any of you worked on this, can you please share the code with me.

The general method would be to import the text file (csv) into Access (into a temporary table), then manipulate the data from the temporary table into the correct locations using queries/code etc.

Don't walk in front of me, I may not follow;
Don't walk behind me, I may not lead;
Just bugger off and leave me alone!!

Hi everyone.
I'm making a custom tool for registering working hours for my employer against a Visual FoxPro database.
I've created a procedure for executing sql queries against the database, but my insert statments aren't commited.
The return value (affected rows) says that the query was successfull.
I'm using a normal "insert into (col1, col2, col(n)) VALUES(val1, val2, val(n))" statement - so nothing fancy.
I've tried using transactions and myTransaction.Commit(); without success.
I've also tried using keywords like "GO" or "COMMIT" in the query - but the FoxPro ODBC driver isn't too keen on those keywords. 
Am I missing something here?
I thought ODBCCommand.ExecuteNonQuery() used the auto-commit property.
Is there and specific properties that must be set, or keywords I must include to make it commit?
Sidenote:
If I copy/paste the query into an ODBC tool (freeware tool I just downloaded for testing purpouses) and execute the query,
the row is added successfully.
I'd really appreciate any feedback you've got.

I copied the database into a cvs folderstructure the other day.
Forgot to update the configuration file with the connectionstring the very next day...

Hello.
I have a _CommandPtr that has the type CommandTypeEnum::adCmdTex, and the CommandText a query("Select test from Table_1") and this select returns one row and one column that has a binary data(image) in it.
<br />
CommandPtr pCommand;<br />
pCommand.CreateInstance(__uuidof(Command)); <br />
pCommand->ActiveConnection = this->pConnection;<br />
pCommand->CommandType = CommandTypeEnum::adCmdText;<br />
pCommand->CommandText = _bstr_t("select test from Table_1"); <br />
<br />
pRecordset = pCommand->Execute(NULL,NULL,CommandTypeEnum::adCmdText); <br />
BYTE* buffer = NULL;<br />
if(pRecordset != NULL)<br />
{<br />
while (!pRecordset->GetEndOfFile())<br />
{<br />
VARIANT var = pRecordset->Fields->GetItem("test")->Value;<br />
void * pData = NULL;<br />
SafeArrayAccessData(var.parray, &pData);<br />
long size = GetArraySize(var, NULL);<br />
buffer = new BYTE[size];<br />
memcpy(buffer, pData, size);<br />
SafeArrayUnaccessData(var.parray); <br />
pRecordset->MoveNext();<br />
}<br />
pRecordset->Close();<br />
}<br />
where
<br />
long GetArraySize(const VARIANT& var, long * nElems)<br />
{<br />
if ( !(var.vt & VT_ARRAY) ) return -1; <br />
<br />
long size = 0;<br />
long dims = SafeArrayGetDim(var.parray);<br />
long elemSize = SafeArrayGetElemsize(var.parray);<br />
long elems = 1;<br />
for ( long i=1; i <= dims; i++ )<br />
{<br />
long lbound, ubound;<br />
SafeArrayGetLBound(var.parray, i, &lbound);<br />
SafeArrayGetUBound(var.parray, i, &ubound);<br />
elems *= (ubound - lbound + 1);<br />
}<br />
<br />
if ( nElems ) *nElems = elems;<br />
<br />
size = elems*elemSize;<br />
return size;<br />
}<br />
When I debug the application, I get the record in the VARIANT var = pRecordset->Fields->GetItem("test")->Value; but when I put par.parray in Memory explorer in VS, i only see this data "fe ee fe ee fe ee fe ee fe ee fe ee fe ee ...fe ee" and of course it brakes at
SafeArrayGetLBound(var.parray, i, &lbound);
Can someone tell me where I am doing a very bad thing?
P.S. I was able to read the binary data correctly from the server using C#.NET 2.0.

I found the solution... it's the GetChunck method....
<br />
if(pRecordset != NULL)<br />
{<br />
while (!pRecordset->GetEndOfFile())<br />
{<br />
ADO_LONGPTR size = pRecordset->Fields->Item["test"]->ActualSize;<br />
<br />
BYTE* buffer = new BYTE[size];<br />
_variant_t varChunk;<br />
varChunk = pRecordset->Fields->Item["test"]->GetChunk(size);<br />
<br />
BYTE * pData = NULL;<br />
SafeArrayAccessData(varChunk.parray, (void HUGEP* FAR*)&pData);<br />
memcpy(buffer, pData, size);<br />
SafeArrayUnaccessData(varChunk.parray);<br />
<br />
ofstream myFile ("C:\\Blue hills.jpg", ios::out | ios::binary);<br />
myFile.write((char*)buffer, size);<br />
myFile.flush();<br />
<br />
pRecordset->MoveNext();<br />
}<br />
pRecordset->Close();<br />
}<br />
<br />

if i run my view in the Designer at hte Enterprise manager i get that error message.. but if i run it through the SQL analyzer it's fine it wont have any errors..

You are Using any field which is keyword
so use all field name with [] ex//
Select name,group from employee
Select [name],[group] from [employee]

ei tnx so much..
at least now i got a hint cause i dont know where to start fixing that error..

In a transaction block if any error for insert or update occures (e.g. caused by foreign key-primary key constraint violation) does the transaction automatically rolls back or do we need to manually roll it back ?
|
|
|
|
|
Syntax will go like this:
<br />
Begin Try<br />
Begin Transaction<br />
--Your Line of code<br />
Commit Transaction<br />
End Try<br />
Begin Catch<br />
RollBack Transaction<br />
End Catch<br />
--Your line of code<br />
You will have to call commit or rollback for your transaction.....
|
|
|
|
|
Does such syntax really exist ? I am using SQL Server 2000. and I get error when runnig such code.It doesn't know TRY keyword.
|
|
|
|
|
It will rollBack "autopmatically" if you will say so.
E.G.
BEGIN TRAN
your code
if @@error <> 0 goto err
-- more code
if @@error <> 0 goto err
At the end:
commit tran<br />
return 1<br />
<br />
err:<br />
rollback tran<br />
return 0
Sincerely,
Elina
Life is great!!!
Enjoy every moment of it!
