错误：当前事务中止，命令被忽略，直到事务块结束—从Aqua Studio导出数据

Question

I am trying to export one table from Aquastudio into CSV file. The table has approximately 4.4 million rows. When I am trying to use the export window function in the aqua studio, I am facing the following error:

Error: ERROR: current transaction is aborted, commands ignored until end of transaction block

I am not understanding what the problem is. I read few articles regarding this error and found that this is happening due to some error in the last postgreSQL command. I did not use any SQL commands for this export and I dont know how to debug this. I am also unable to view the log files.

Answer 1

Use rollback to cancel the previous query. After that, you will be able to execute your current query.

Answer 2

You probably shouldn't be exporting millions of rows through a JDBC/ODBC connection, especially for Redshift.

For Redshift, please use the UNLOAD command documented here . You'll have to UNLOAD the file to S3 and download it from there.

For Postgres, use COPY TO as documented here .
