ExecuteScaler and ExecuteReader in 7.5.2 web Your last visit to this thread was on 1/1/1970 12:00:00 AM

I can get ExcuteScaler to work in a C# Snippet, but I can't get ExecuteReader to work to retrieve multiple records from oracle. Support appreciated.

strSQLOwnerInfo = " Select userid from userinfo";
using (System.Data.OleDb.OleDbConnection connownerinfo = new System.Data.OleDb.OleDbConnection(datasvc.GetConnectionString()))
{
connownerinfo.Open();
using (System.Data.OleDb.OleDbCommand cmd = new System.Data.OleDb.OleDbCommand(strSQLOwnerInfo, connownerinfo))
{
rdrownerinfo = cmd.ExecuteReader();
while (rdrownerinfo.Read())
{
UID = (string)rdrownerinfo["userid"];
}
}

What is the error you're getting? That will definitely help.

Also, have you tried upper casing the table and field names? If the Oracle implementation is case-sensitive then that would be a problem.

Is this all the code? I hope not - for a start you havent declared the datareader..also dont you hgave to use a ToString() after the rdownerinfo["userid"]? Incidentially you should use the co;lumn ordinal as (apparently) its quicker so rdownerinfo[0].ToString(); If you use a tostring() you wont have to cast either.

Also its worth noting that if you are just setting the same UID every time it will always be one value (even it if it has looped through all the records). You would have to append the values to the variable or do whatever you have to. Grandma.....suck eggs....sorry you have probably left out your code for the post but worth checking.
