Locate (locate)

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

Description

The column created returns the position of the first occurrence of a specified value in a string, counting from 0. 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 Locate operation. You need to specify two arguments:

Argument	Data type

Argument	Data type
String ^mandatory	string
Substring to locate ^mandatory	string

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

Example

In the demo.ecommerce.data table, we want to know the position of the ? character in the strings of the uri column. To do it, we will create a new column using the Locate operation.

The arguments needed to create the new column are:

String - uri column
Substring to locate - ?

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 Locate operation:

locate(string, string_to_locate)

Example

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

from demo.ecommerce.data
  select locate(uri, "?") as `uri_locate_?`
