Hi, Which behavior are you looking for ? If you want the following statements to succeed, I guess that you don't want to be in a transaction context. In this case, you should have a look at the following link : https://www.postgresql.org/docs/11/ecpg-commands.html By default, the AUTOCOMMIT is OFF but you can set it to ON and it should solve your issue as only explicit transactions will keep a transaction context.

All subsequent correct (SELECT ...) statements get rejected with, for example: ... posDebug: [27.12.2019 15:20:59:044] stmt: SELECT ctid, * from titel_datum WHERE desk>='31.12.1900' AND feldnr IN ( 2 ) ORDER BY desk ASC , feldnr ASC posDebug: [27.12.2019 15:20:59:044] ESQL: PREPARE sid_titel_datum FROM :select_anw; ==== sqlca ==== sqlcode: -400 sqlerrm.sqlerrml: 105 sqlerrm.sqlerrmc: current transaction is aborted, commands ignored until end of transaction block on line 918 sqlerrd: 0 0 0 0 0 0 sqlwarn: 0 0 0 0 0 0 0 0 sqlstate: 25P02 ========posSqlError======= ... Note: we are not in some kind TRANSACTION block, like 'EXEC SQL BEGIN TRANSACTION;' What is the correct way to abort the "transaction" as requested by the PG server to return to normal operations?
