Very very useful! Is it possible to create a table via a dblink query without specifying the data types of the attributes in the select list? Simon, Unfortunately there is no way to do it to my knowledge without specifying the datatype. Its an issue with stored functions that return untyped rows as well such as the tablefunc crosstab feature.

I haven't checked in 8. I suspect it hasn't but has come up quite a bit in discussions. This is a good posting and thought I'd give it a try. But ran into trouble when I tried connecting to my local SQL server. This there something different I need to do? Regards, Flex.

Thanks a lot, i am very dizzy to find this out Example:. Can any one help me in loading the dblink. Mohame, What sort of problem are you running into? Since dblink can be used with any query, it is declared to return record , rather than specifying any particular set of columns.

This means that you must specify the expected set of columns in the calling query — otherwise PostgreSQL would not know what to expect. Here is an example:. At run time, an error will be thrown if the actual query result from the remote database does not have the same number of columns shown in the FROM clause.

The column names need not match, however, and dblink does not insist on exact type matches either. It will succeed so long as the returned data strings are valid input for the column type declared in the FROM clause.
