Data Resource - Target Data URI

Undraw Environment


A target uri is a uri that defines one or more target resources for data transfer operations.


Reusing the name of the source in the target

The below target data uri


will define the target resource

  • located in the sqlite connection
  • and a name that is composed of

Example: if the source table name is time, the target table name would be new_time

Using a part of source name in the target

With a glob pattern, you can reference parts of the source.

Example with the below data selector


and the below target data uri

  • if the source table name were D_TIME, D_CUSTOMERS,
  • the target table names would be TIME, CUSTOMERS

File system

In a shell such as powsershell, the $ character should be quoted. (That's why we recommand bash)

tabli data copy '*/bootstrap.min.css@cd' '/boot/bootstrap.$1.min.css@cd'




  • connection is the name of a connection
  • pattern is an expression that define the name of the target. This pattern can include the captured characters from the data selector glob expression.

Glob Backreference

In the pattern, you can reference a globbing matched wildcard from a data source selector using the x syntax where x indicates the index of a glob pattern. ie

  • 0 defines the whole expression (ie the whole path)
  • 1 defines the first matched wildcard
  • 2 defines the second matched wildcard
  • and so on until 9.

You can see the value of the back reference with the tabli data list command. If you want to know the value of 1, just ask for the attribute 1

Example with tpcds where we want to capture the name of the web table but without the prefix.

tabli data list  -a name -a 1 web_*@tpcds
name          1         
-----------   -------   
web_page      page      
web_returns   returns   
web_sales     sales     
web_site      site

Attribute Reference

In the pattern, you can reference a resource attribute using the x or x syntax where x indicates the name of the attribute.


You can see all available attributes with the data info command.

tabli data info web_page@tpcds
