To get specific words in the output of an Oracle query, you can use the following approach:

  1. Use the SUBSTR function: You can use the SUBSTR function in your SELECT statement to extract specific words from a column.


For example, if you have a column name "words" that contains a sentence, and you want to extract the first word from that sentence, you can use the following query:

1
2
SELECT SUBSTR(words, 1, INSTR(words, ' ') - 1) AS first_word
FROM your_table;


  1. Use the REGEXP_SUBSTR function: If you need to extract words based on a pattern or regular expression, you can use the REGEXP_SUBSTR function.


For example, if you want to extract all words that start with the letter "A" from a column, you can use the following query:

1
2
SELECT REGEXP_SUBSTR(words, 'Aw+', 1, 1) AS words_starting_with_A
FROM your_table;


By using these functions and techniques, you can easily extract specific words from the output of an Oracle query.
