Oracle Extract Numbers From Field Guide
To extract numbers from a field, you can use regular expressions to match numerical characters. In Oracle, you can achieve this using the REGEXP_SUBSTR function.
To extract numbers from a field, you can use the following query statement:
Extract the digits from the column in the table using regular expressions.
Among them, column_name is the name of the field from which numbers are to be extracted, and table_name is the name of the table that contains this field.
For example, if you want to extract numbers from the “content” field of a table named “test_table,” you can use the following query:
Get the numerical value from the content column in the test_table.
In this way, you can extract the numbers from the content field.
