Trim the left side (ltrim)
Removes all the extra spaces from the beginning of a string.
How does it work in the search window?
This operation needs only one argument:
|String to be trimmed (mandatory)||string|
The data type of the new column is string.
We want to remove the blank spaces at the left side of the values in one of the columns of this file.
To try this example, first upload the file as a lookup table (name it trim_operations). Once uploaded, go to Data Search → Finder and access the my.lookup.trim_operations table.
Then, select Create column from the query toolbar and select Trim the left side as the operation. The arguments needed are:
- String to be trimmed - trim_left column
The result is not visible in the interface, since the search window table automatically trims blank spaces at both sides of the strings. Select Download from the toolbar and download the data as a CSV to see the data trimmed.
