Hi Follow up on the previous thread, I wanted to implement bulk insert in single transaction. I have tested using db:add and db:store and that seems to be working. However, using db:store, it appears that the file needed to be persisted in the file system, which is one of the limitation that I have. I’m currently having these files as InputStream for binary, is there a way that I can insert binary files in a single batch transaction using basexclient basex/BaseXClient.java at master · BaseXdb/basex · GitHub<https://github.com/BaseXdb/basex/blob/master/basex-examples/src/main/java/org/basex/examples/api/BaseXClient.java> ? Or some other alternative ?

BaseX script executed each command separately. This is by design and required by the nature of XQuery (Update), which by design always executes as one transaction - Which can be difficult do deal with if you have a large amount of data and have to e.g. hold it in memory. Each XQuery runs in one single transaction, so you can simply add your documents via XQuery, e.g. db:add("DB", "embedded7.xml"), db:add("DB", "embedded8.xml") Cheers Dirk On 05/19/2016 08:11 PM, Wang, Genneva wrote: Hi I’m trying to figure out whether batched transaction would work for basex, and I came across the RUN and EXECUTE command specified in http://files.basex.org/releases/8.4/BaseX84.pdf page 58-59. The document mentioned following in the summary section: RUN:Evaluates the contents of file as XQuery expression. If the file ends with the suffix .bxs, the file content will be evaluated as command script. This command can be used to run several commands in a single transaction EXECUTE: Evaluates the specified input as command script. This command can be used to run several commands in a single transaction. I’ve tried this myself For example, I’d like to know if I batch 2 inserts, if one fails, would both inserts get rollback. I’m using a simple .bxs (attached and also listed below for your convenience) and run the execute using GUI. OPEN test ADD TO embedded7.xml <root>embedded</root> ADD TO embedded8.xml <root>embedded CLOSE The second ADD (embedded8.xml) is not a valid xml format so I’m expecting it to fail, and rollback both files if any of them have already added. But after executing this script, I’m seeing embedded7.xml have been added. Would you be able to confirm if this is the expected behavior ? If so, is there anyway that I can batch multiple inserts and ensures that these batch of files can be committed at the same time, and rollback all together if any of the file has an error ?
