About
data delete is a tabli command that supports the delete data operation where the data to delete are defined in a source data resource.
This is an alias command of the data transfer command where the transfer-operation option has been set to delete.
Prerequisites
- The target data resource should have at minimum a primary key or a unique key.
- The source data resource should have at minimum a primary key or a unique key of the target data resource
Syntax
tabli data delete -h
Tabli data delete
=================
Delete one or more records of data resources that are present in other data resources.
Note: This is an alias command to the `transfer` command with the `delete` transfer operation.
Examples
--------
1 - To delete the records of the Sql query `query_11.sql` from the Sql table `analytics`, you would execute
tabli data delete (query_11.sql)@sqlite analytics@sqlite
2 - To delete the records of the file `foo.csv` from the `sqlite` table `foo`, you would execute
tabli data delete foo.csv foo@sqlite

-bs,--buffer-size <bufferSize> defines the size of the memory buffer between the source and target threads
-mdu,--metrics-data-uri <metricsDataUri> defines a target data uri where the data metrics should be exported
-sfs,--source-fetch-size <fetchSize> defines the fetch size against the source connection
-tbs,--target-batch-size <batchSize> defines the batch size against the target data resource
-tcf,--target-commit-frequency <commitFrequency> defines the commit frequency in number of batches against the target data resource
-tw,--target-worker <targetWorkerCount> defines the target number of thread against the target connection
-wbv,--with-bind-variables defines if bind variables are used in the SQL statement
