01422, 00000, "exact fetch returns more than requested number of rows"
// *Cause: The number specified in exact fetch is less than the rows returned.
// *Action: Rewrite the query or change number of rows requested
Your query returns multiple rows, you need to change it to return only one row.

WHERE clause should be modified so that SELECT returns just one row for each record in a block.
Sometimes SELECT DISTINCT helps.
Or, using an aggregate function such as SELECT MAX(NAME), MAX(DESCRIPTION) ... does the job.
However, it is you who has to investigate all options and apply the most appropriate one.

Quote:yes, it has one or more records to Display in the Detail block.
If there is more than one record, then you have to loop through the record set to process/display each row.
select Name, description, nvl(title),0)
into :blk1.name, :blk1.expl, :blk1.sub
from table1
where pid = :blk1.pid;
If all of the values are from a single table, why not simply create a block based on this table and set the WHERE_CLAUSE of the block to filter the records by the :BLK1.PID?

If this detail block is a database block (nobody said that it isn't) and POST-QUERY is used to populate non-database items, then I disagree with you, Craig.
