Enter the number of rows to initially retrieve when executing a query in the SQL Editor or the Query Builder.

When you scroll through the Results grid, additional records are retrieved on demand (Oracle) or through re-execution (other platforms). Default: 1000 Unlimited—Return all rows for a query. Caution: Selecting unlimited rows can impact performance and memory usage when querying a large table. Default: Cleared
