How to Extract Day In Char In Oracle?

To extract the day from a date column in Oracle, you can use the TO_CHAR function along with the 'DD' format model.

For example, if you have a column named "date_column" in a table called "table_name", you can extract the day as a character using the following SQL query:

SELECT TO_CHAR(date_column, 'DD') AS day_char FROM table_name;

This query will return the day of the month as a character for each date in the "date_column" column of the "table_name" table.

How can I extract the day from a char field in Oracle?

You can use the TO_CHAR function in Oracle to extract the day from a char field. Here's an example of how you can extract the day from a char field called my_date_field:

1
2

SELECT TO_CHAR(TO_DATE(my_date_field, 'YYYY-MM-DD'), 'DD') AS day
FROM your_table_name;

In this example, TO_DATE function converts the char field my_date_field into a date format, and then TO_CHAR function extracts the day from that date in the 'DD' format. You can adjust the date format in the TO_DATE function according to the format of your char field.

How to convert varchar2 to date and extract day in Oracle?

To convert a VARCHAR2 column to a DATE data type and extract the day from the date in Oracle, you can use the following SQL query:

1
2
3

SELECT TO_DATE(your_varchar_column, 'format_mask') AS converted_date,
       EXTRACT(DAY FROM TO_DATE(your_varchar_column, 'format_mask')) AS day
FROM your_table;

In the above query:

• Replace your_varchar_column with the name of your VARCHAR2 column that contains the date values.
• Replace 'format_mask' with the appropriate format model that matches the date format in your VARCHAR2 column (e.g., 'YYYY-MM-DD').
• Replace your_table with the name of your table.

By using the TO_DATE function, you can convert the VARCHAR2 column to a DATE data type. Then, you can use the EXTRACT function to extract the day from the converted date.

Example: If your VARCHAR2 column contains dates in the format 'YYYY-MM-DD', you can use the following query:

1
2
3

SELECT TO_DATE(date_column, 'YYYY-MM-DD') AS converted_date,
       EXTRACT(DAY FROM TO_DATE(date_column, 'YYYY-MM-DD')) AS day
FROM your_table;

How to extract day from string in Oracle?

SELECT EXTRACT(DAY FROM TO_DATE('2022-05-15', 'YYYY-MM-DD')) AS day
FROM dual;

This query will extract the day from the string '2022-05-15' and return the day as a number. You can replace '2022-05-15' with any string that represents a date in the format specified in the TO_DATE function.

How to convert char to date and extract day in Oracle?

To convert a character data type (char) to a date data type and extract the day from the date in Oracle, you can use the TO_DATE function to convert the char to a date, and then the EXTRACT function to extract the day from the date.

Here is an example SQL query that demonstrates how to convert a char to a date and extract the day in Oracle:

1
2

SELECT EXTRACT(DAY FROM TO_DATE('20220115', 'YYYYMMDD')) AS extracted_day 
FROM dual;

In this query:

1. '20220115' is the input char value that represents a date in the format 'YYYYMMDD'.
2. TO_DATE function is used to convert the char value to a date value.
3. EXTRACT function is used to extract the day from the converted date value.
4. 'extracted_day' is the alias given to the extracted day value in the result.

You can replace '20220115' with your char value and 'YYYYMMDD' with the appropriate format to match your input date format.

How to extract only day from char in Oracle?

You can extract only the day from a date stored as a char datatype by using the SUBSTR function in Oracle. Here is an example query:

1
2

SELECT SUBSTR('2022-12-31 12:30:45', 9, 2) AS day
FROM dual;

This query will extract the day '31' from the input date '2022-12-31 12:30:45' by starting at character position 9 and taking 2 characters.

You can replace the input date with your char datatype column name to extract the day from the actual data in the table.

SELECT TO_DATE('05-JAN-2022', 'DD-MON-YYYY') AS date_value
FROM dual;

-- Extract day from date
SELECT EXTRACT(DAY FROM TO_DATE('05-JAN-2022', 'DD-MON-YYYY')) AS day_value
FROM dual;

In the above example, we first convert the string '05-JAN-2022' to a date using the TO_DATE function with the format mask 'DD-MON-YYYY'. Then we extract the day from the resulting date using the EXTRACT function. The output will be the day value, which in this case is 5.
