Replace all (replaceall)
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 |
|---|---|
| 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
