I got a piece of code to check the existence of a table from . This is applicable for [^]. The revised code for OleDB is below:

C#

public bool CheckTableExist(OleDbConnection conn, string tblName)
{
    bool b = false;
    string[] restrictions = new string[]  { null, null, tblName };
    DataTable dTable = conn.GetSchema("Tables", restrictions);
    if (dTable.Rows.Count == 0)
    {
        b = false;
    }
    else
    {
        b = true;
    }
    return b;
}

This may also be applicable for SQL Server, or any other OLE database, but is NOT for Oracle DB. How to check the existence of a table in Oracle DB? Thanks in advance if you can share your experience.

You can usually find this in Oracle by checking the user_tables object.

Something like this should do it:

SQL

SELECT COUNT(table_name) FROM user_tables WHERE table_name='tlbNameToCheckFor'

Dear hypermellow:
Thanks for your post. I test this sql statement in Oracle SQL Developer. It works fine.
