To get the number between special characters in Oracle, you can use the SUBSTR function along with INSTR function.
Here is an example query: SELECT SUBSTR(column_name, INSTR(column_name, '[', 1, 1) + 1, INSTR(column_name, ']', 1, 1) - INSTR(column_name, '[', 1, 1) - 1) AS number_between_special_chars FROM table_name;
This query will extract the number between the first occurrence of '[' and ']' in the column_name column of the table_name table. You can modify the query to extract numbers between different special characters as needed.

What is the most effective way to extract a numerical value between special characters in Oracle?
The most effective way to extract a numerical value between special characters in Oracle is by using regular expressions. You can use the REGEXP_SUBSTR function to search for a specific pattern within a string and extract the numerical value between the special characters.
For example, if you want to extract a numerical value between parentheses in a string, you can use the following query:
1
|
SELECT REGEXP_SUBSTR(column_name, '\((\d+)\)', 1, 1, NULL, 1) AS extracted_value FROM table_name;
|
In this query, \((\d+)\) is the regular expression pattern that matches a numerical value between parentheses. The (\d+) part of the pattern captures the numerical value, and the REGEXP_SUBSTR function extracts it from the string.
You can adjust the regular expression pattern based on the specific special characters you are trying to extract the numerical value between.
How to get number between special character in oracle?
You can use the REGEXP_SUBSTR function in Oracle to extract numbers between special characters. Here's an example query that extracts numbers between parentheses:
1 2 |
SELECT REGEXP_SUBSTR(your_column, '\((\d+)\)', 1, 1, NULL, 1) AS extracted_number FROM your_table; |
In this query:
- your_column is the column in your table that contains the text with the numbers between parentheses.
- your_table is the table where the data is stored.
- '\((\d+)\)' is the regular expression pattern that matches numbers between parentheses.
- 1, 1, NULL, 1 are parameters that specify where to start searching, how many occurrences to match, and which subexpression to return.
You can adjust the regular expression pattern and parameters as needed to extract numbers between different special characters.
How to extract numerical values between special characters in Oracle?
To extract numerical values between special characters in Oracle, you can use a combination of functions such as REGEXP_SUBSTR and regular expressions. Here is an example query that demonstrates how to extract numerical values between parentheses:
1 2 |
SELECT REGEXP_SUBSTR(column_name, '\(([0-9]+)\)', 1, 1, NULL, 1) AS extracted_value FROM your_table; |
In this query:
- column_name is the name of the column in your table that contains the data you want to extract from.
- '\(([0-9]+)\)' is the regular expression pattern that matches the numerical values between parentheses. It looks for a left parenthesis followed by one or more digits followed by a right parenthesis.
- 1, 1, NULL, 1 are additional parameters for the REGEXP_SUBSTR function that specify the start position, occurrence number, match parameter, and subexpression number to extract.
You can adjust the regular expression pattern and parameters as needed to extract numerical values between different special characters in your data.
How to extract numeric content enclosed by special characters in Oracle?
You can use the REGEXP_SUBSTR function in Oracle to extract numeric content enclosed by special characters. Here's an example of how you can achieve this:
1 2 3 |
SELECT REGEXP_SUBSTR(column_name, '\d+', 1, 1) AS extracted_number FROM your_table WHERE REGEXP_LIKE(column_name, '[^0-9]||\d+||[^0-9]') |
In this query:
- Replace "column_name" with the name of the column containing the data you want to extract from.
- Replace "your_table" with the name of the table containing the column.
- The REGEXP_SUBSTR function is used to extract the numeric content from the column.
- '\d+' specifies that we want to extract one or more numeric characters.
- The REGEXP_LIKE function is used to filter out any rows that do not contain any numeric content enclosed by special characters.
This query will return the numeric content enclosed by special characters from the specified column in your table.
What is the syntax for extracting numbers between special characters in Oracle?
To extract numbers between special characters in Oracle, you can use regular expressions in combination with the REGEXP_SUBSTR function. Here is the syntax to do this:
1 2 |
SELECT REGEXP_SUBSTR(column_name, 'pattern') FROM table_name; |
In the above syntax:
- column_name is the name of the column containing the data you want to extract numbers from.
- pattern is the regular expression pattern that defines the special characters and numbers you want to extract.
For example, if you want to extract numbers between parentheses in a column called "description", you can use the following query:
1 2 |
SELECT REGEXP_SUBSTR(description, '\((\d+)\)', 1, 1, NULL, 1) FROM table_name; |
In this example, the regular expression pattern '((\d+))' captures any numbers between parentheses in the "description" column. The \d+ part matches one or more digits, while the parentheses () are used to capture the matching numbers.
