Question/Problem Description
Error occurs when running a SELECT query via JDBC or ODBC.

Error indicates a failure to get a record lock.

Error occurs when isolation level is set to one of the following:
  • Read Committed
  • Repeatable Read
  • Serializable
Steps to Reproduce

Defect Number
Enhancement Number
SELECT statements are being run while connected with Read Committed, Repeatable Read, or Serializable set as the Isolation Level. These isolation levels will place a share lock on the record while it is being read.
Option #1 - applies from OpenEdge 10.1A02 and later.
Use the "WITH (NOLOCK)" hint in the SELECT query. This ensures that no record locks are acquired. For example,

SELECT * FROM pub.customer WITH (NOLOCK);

The "WITH (NOLOCK)" hint is similar to using the Read Uncommitted isolation level in that it will result in a dirty read.

Option #2 - applies to all OpenEdge (10.x/11.x) versions using the Read Committed isolation level.
Use the "WITH (READPAST)" hint in the SELECT query. This option causes a transaction to skip rows locked by other transactions that would ordinarily appear in the result set, rather than block the transaction waiting for the other transactions to release their locks on these rows. For example,


Please be aware that this can lead to fewer records being returned than expected since locked records are skipped/omitted from the result set.

Option #3 - applies to all Progress/OpenEdge versions.
Change the Isolation Level to Read Uncommitted to ensure that, when a record is read, no record locks are acquired. Using the Read Uncommitted isolation level will result in a dirty read.
This can be done at ODBC DSN level or via the SET TRANSACTION ISOLATION LEVEL <isolation_level_name> statement. For example,
