SQL_OneValue

string Column_ID
string SQL_Command


Accepts and executes a SQL command on the current default connection. It then fetches the first row of the result, and if it can find the named column, returns its value.

Any failure at any stage returns false.

Be careful that the SQL_Command actually return one or at most a few rows, if a command is issued to the server that would return 1 million rows, the server will execute the entire command, even though it only returns the first row to PHP.
