Programmer response
For a result set locator there are two
common causes for the error:
- The host variable used as a result set locator was never assigned a valid result set locator value. Result set locator values are returned by the DESCRIBE PROCEDURE and ASSOCIATE LOCATORS statements. Make sure the value in your host variable is obtained from one of these statements.
- Result set locator values are only valid as long as the underlying SQL cursor is open. If a commit or rollback operation closes an SQL cursor, the result set locator associated with the cursor is no longer valid.
For a LOB locator, some common causes for the error are:
- The host variable used as a LOB locator was never assigned a valid LOB value.
- A commit or rollback operation or an SQL FREE LOCATOR statement freed the locator.
For a table locator, the error commonly occurs when the host variable that was used as a table locator was never assigned a valid table locator value.
