How to Extract Text Between Two Words In Oracle?

To extract text between two words in Oracle, you can use the combination of functions such as SUBSTR, INSTR, and LENGTH. Here is an example query that extracts text between two words "start" and "end":

1
2
3
4
5

SELECT SUBSTR(your_column, 
              INSTR(your_column, 'start') + LENGTH('start'), 
              INSTR(your_column, 'end', INSTR(your_column, 'start')) 
              - INSTR(your_column, 'start') - LENGTH('start')) AS extracted_text
FROM your_table;

Replace "your_column" with the column containing the text, and "your_table" with the table name. This query will retrieve the text between the words "start" and "end" from the specified column.

What is the correct SQL syntax for retrieving text between two specific words in Oracle?

In Oracle, you can use the SUBSTR function along with INSTR function to retrieve text between two specific words. Here is the correct SQL syntax:

1
2
3
4

SELECT SUBSTR(column_name, INSTR(column_name, 'start_word') + LENGTH('start_word'), 
                     INSTR(column_name, 'end_word') - INSTR(column_name, 'start_word') - LENGTH('start_word'))
FROM table_name
WHERE column_name LIKE '%start_word%end_word%';

Replace column_name, table_name, start_word, and end_word with your actual column name, table name, and the words you want to extract the text between.

How can I extract information between two words in an Oracle database query?

You can use the SUBSTR function in Oracle to extract information between two words in a database query. Here's an example:

1
2
3
4

SELECT SUBSTR(your_column, 
              INSTR(your_column, 'first_word') + LENGTH('first_word'), 
              INSTR(your_column, 'second_word') - INSTR(your_column, 'first_word') - LENGTH('first_word')) 
FROM your_table;

In this example, replace your_column with the column that contains the text you want to extract information from, your_table with the table where the column is located, first_word with the starting word, and second_word with the ending word.

The SUBSTR function extracts a substring from a string, using the INSTR function to find the position of the starting and ending words within the column. The length of the starting word is added to the starting position to exclude it from the extracted substring, and the difference between the positions of the ending and starting words is used to determine the length of the extracted substring.

Please note that this approach assumes that the starting and ending words only appear once in the column. If they appear multiple times, you may need to adjust the query accordingly.

What function should I use to extract text between two specific strings in Oracle SQL?

You can use the SUBSTR function in Oracle SQL to extract text between two specific strings. Here is an example of how you can use the SUBSTR function to extract text between two specific strings:

1
2
3
4
5

SELECT SUBSTR(column_name, 
              INSTR(column_name, 'start_string') + LENGTH('start_string'),
              INSTR(column_name, 'end_string') - INSTR(column_name, 'start_string') - LENGTH('start_string')) AS extracted_text
FROM your_table;

In this example, column_name is the column from which you want to extract the text, 'start_string' is the starting string from which you want to extract the text, and 'end_string' is the ending string after which you want to stop extracting the text. The SUBSTR function is used to extract the text between the position of the starting string and the position of the ending string in the column data.

What is the easiest technique for extracting text between two words in Oracle SQL?

One common technique for extracting text between two words in Oracle SQL is to use the SUBSTR function in combination with the INSTR function.

For example, if you have a string 'The quick brown fox jumps over the lazy dog' and you want to extract the text between the words 'quick' and 'jumps', you can use the following query:

1
2
3
4
5
6

SELECT SUBSTR(
         your_column,
         INSTR(your_column, 'quick') + LENGTH('quick') + 1,
         INSTR(your_column, 'jumps') - INSTR(your_column, 'quick') - LENGTH('quick') - 1
       ) AS extracted_text
FROM your_table;

This query uses the INSTR function to find the positions of the 'quick' and 'jumps' words in the string, then uses the SUBSTR function to extract the text between these two positions.

Note that this technique assumes that the words 'quick' and 'jumps' appear only once in the string. If they appear multiple times, additional logic will be needed to handle this scenario.
