Replace all (replaceall)

[ 1 Description ] [ 2 How does it work in the search window? ] [ 3 How does it work in LINQ? ]

Description

Searches for a value in a given string and returns a new string where all the occurrences (if any) are replaced by another indicated value. Note that this operation is case sensitive.

How does it work in the search window?

Select Create column in the search window toolbar, then select the Replace all operation. You need to specify three arguments:

Argument	Data type

Argument	Data type
Starting string ^mandatory	string
Substring to search ^mandatory	string
Substring to replace ^mandatory	string

The data type of the values in the new column is string.

Example

In the demo.ecommerce.data table, we want to create a new column that replaces LOG by log in all the strings of the uri column. To do it, we will create a new column using the Replace all operation.

The arguments needed to create the new column are:

String - uri column
Substring to search - Click the pencil icon and enter LOG
Substring to replace - Click the pencil icon and enter log

Click Create column and you will see the following result:

How does it work in LINQ?

Use the operator select... as... and add the operation syntax to create the new column. This is the syntax for the Replace all operation:

replaceall(string, string_to_search, string_to_replace)

Example

You can copy the following LINQ script and try the above example on the demo.ecommerce.data table.

from demo.ecommerce.data
  select replaceall(uri, "LOG", "log") as LOGtolog
