To get a number between special characters in Oracle, you can use the REGEXP_SUBSTR function. This function allows you to extract a specific pattern from a string based on a regular expression.
For example, if you have a string like 'abc123xyz' and you want to extract the number '123' from it, you can use the following query: SELECT REGEXP_SUBSTR('abc123xyz', '\d+') FROM dual;
In this query, '\d+' is the regular expression pattern that matches any sequence of digits. The REGEXP_SUBSTR function extracts this pattern from the input string and returns the result.
You can customize the regular expression pattern based on your specific requirements to extract numbers between special characters in Oracle.
How to get numbers between special characters in Oracle?
You can use the REGEXP_REPLACE function in Oracle to extract numbers between special characters. Here is an example of how you can achieve this:
1 2 |
SELECT REGEXP_REPLACE('This is a sample string with numbers 123 in between', '[^0-9]+', ',') AS numbers FROM dual; |
In this example, the regular expression '[^0-9]+' matches any non-numeric characters and replaces them with a comma. This will leave only the numbers in the original string.
You can adjust the regular expression pattern according to your specific requirements and the special characters you are looking for.
How to parse text and get numbers between special characters in Oracle?
To parse text and extract numbers between special characters in Oracle, you can use a combination of string functions such as REGEXP_SUBSTR and REGEXP_REPLACE.
Here is an example of how you can extract numbers between special characters in Oracle:
1 2 3 |
SELECT REGEXP_REPLACE(REGEXP_SUBSTR(column_name, '\((\d+)\)'), '[^0-9]', '') AS extracted_number FROM your_table; |
In this query:
- REGEXP_SUBSTR(column_name, '\((\d+)\') extracts the numbers between parentheses from the column values.
- REGEXP_REPLACE(..., '[^0-9]', '') removes any non-numeric characters from the extracted string to get only the numbers.
You can adjust the regular expression pattern in REGEXP_SUBSTR
to match the specific special characters and number format you are looking for in your text.
How to extract numeric values enclosed by parentheses in Oracle?
You can extract numeric values enclosed by parentheses in Oracle using regular expressions and the REGEXP_SUBSTR
function.
Here is an example query to extract numeric values enclosed by parentheses:
1 2 |
SELECT REGEXP_SUBSTR('abc (123) def', '\(\d+\)', 1, 1) AS numeric_value FROM dual; |
In this query:
- 'abc (123) def' is the string containing the numeric value enclosed by parentheses
- '\(\d+\)' is the regular expression pattern that matches numeric values enclosed by parentheses
- 1 is the starting position in the string
- 1 is the occurrence of the pattern to match
This query will return the numeric value 123
extracted from the string 'abc (123) def'
.
You can adjust the regular expression pattern and input string to extract numeric values enclosed by parentheses in different scenarios.
What is the correct procedure to find numbers between brackets in Oracle?
To find numbers between brackets in an Oracle database, you can use the REGEXP_substr function to search for a specific pattern. Here is an example:
1 2 |
SELECT REGEXP_substr(column_name, '\[([0-9]+)\]', 1, 1, null, 1) AS number_in_brackets FROM table_name; |
In this query:
- column_name is the name of the column where you want to search for numbers in brackets.
- table_name is the name of the table where the column is located.
The regular expression pattern used in REGEXP_substr function \[([0-9]+)\]
searches for numbers enclosed in square brackets. The ([0-9]+)
part of the regular expression matches one or more digits.
This query will return the numbers found within brackets in the specified column.
What is the query to extract numerical values between special characters in Oracle?
To extract numerical values between special characters in Oracle, you can use regular expressions with the REGEXP_SUBSTR function. Here is an example query that extracts numerical values between parentheses:
1 2 |
SELECT REGEXP_SUBSTR(column_name, '\((\d+)\)', 1, 1, NULL, 1) AS extracted_number FROM your_table; |
In this query:
- column_name is the name of the column in your table that contains the value between special characters (in this case, parentheses).
- '\((\d+)\)' is the regular expression pattern that matches numerical values between parentheses.
- 1, 1, NULL, 1 are the parameters of the REGEXP_SUBSTR function that specify the starting position, occurrence, match parameter, and subexpression to return.
You can adjust the regular expression pattern and parameters based on the specific special characters and numerical values you are trying to extract.
