Table Existing

[GMV]

Hi,
Could any body tell me the proper way to find a table
whether it exists or not.
I use code:

OleDbConnection dbConnection = new OleDbConnection(ConnectionString);
string InsertQuery = "CREATE TABLE Processed (Cod INTEGER, ProcessDate DATETIME)";
OleDbCommand dbCreateCommand = new OleDbCommand(InsertQuery, dbConnection);
dbDeggyConnection.Open();
dbCreateCommand.ExecuteNonQuery();

But, if table already exist I get an error.
Thx in advance.

the easiest sol. would be keeping try catch blocks

OleDbConnection dbConnection = new OleDbConnection(ConnectionString);
string InsertQuery = "CREATE TABLE Processed (Cod INTEGER, ProcessDate DATETIME)";
OleDbCommand dbCreateCommand ;
try
{
dbCreateCommand = new OleDbCommand(InsertQuery, dbConnection);
}catch
{
}
dbDeggyConnection.Open();
dbCreateCommand.ExecuteNonQuery();

yes, there are other sol. also.

you can access the table info from
a metatable
like
execute the query

SELECT * FROM sysobjects WHERE name = 'TableName'

and check for the results...

rest u know...

forgot to give an example (i tested it on my machine)

SELECT * FROM sysobjects WHERE name = 'pro'

if exists will return with
pro 965578478 U 1 1 1610612736 0 0 0 2003-02-10 10:38:35.190 0 0 0 U 1 67 0 2003-02-10 10:38:35.190 0 0 0 0 0 0 0

these details in SQLDataReader r;

int i=0;
while(r.Read() )
{
i++
}
if( i >=1 )
{
// don't create table
}

else
{
//create table
}

I'm sorry! I have problem with inet connection.

Thx a million!!!

[pareshgh]

why ???
what happened...

SELECT * FROM sysobjects WHERE name = 'TableName'

should work... it gives the existance of a table.
if you are using SQL Server

did you got that..

Hi!
I use Microsoft Access.
I think the problem in that.

[pareshgh]

yeah, look I gave you example with respect to SQL Server,
I don't know that you are having MS Access. so I think for timebeing you should go with try...catch untill 'I'/'you'/someone
finds the correct solution from access table..

rgds,
