To run the LOWER() function on a variable in Oracle, you can simply use the LOWER() function in your SQL query along with the variable you want to convert to lowercase. For example, if you have a variable named 'name' and you want to convert it to lowercase, you can use the following query:
SELECT LOWER(name) FROM your_table;
This will return the 'name' variable in lowercase letters. You can use this function in any SELECT, INSERT, UPDATE, or DELETE query where you want to convert a variable to lowercase.
How to lowercase a column value in Oracle?
To lowercase a column value in Oracle, you can use the LOWER() function in your SQL query. Here is an example:
1 2 |
SELECT LOWER(column_name) AS lowercase_column FROM table_name; |
Replace column_name
with the name of the column you want to lowercase and table_name
with the name of the table containing the column. This query will return the values in the specified column in lowercase.
How to change the case of a variable to lower in Oracle?
To change the case of a variable to lower in Oracle, you can use the LOWER()
function. Here is an example of how you can do this:
1 2 3 4 5 6 |
DECLARE my_variable VARCHAR2(50) := 'Hello World'; BEGIN my_variable := LOWER(my_variable); DBMS_OUTPUT.PUT_LINE(my_variable); END; |
In this example, the LOWER()
function is used to convert the value of the my_variable
to lowercase. The output will be 'hello world'.
How to transform text to lowercase in Oracle PL/SQL?
To transform text to lowercase in Oracle PL/SQL, you can use the LOWER
function. Here is an example:
1 2 3 4 5 6 7 |
DECLARE v_input_text VARCHAR2(100) := 'HELLO WORLD'; v_lower_text VARCHAR2(100); BEGIN v_lower_text := LOWER(v_input_text); DBMS_OUTPUT.PUT_LINE('Lowercase text: ' || v_lower_text); END; |
In this example, the LOWER
function is used to convert the text 'HELLO WORLD' to lowercase, which is then stored in the variable v_lower_text
. The output will be 'hello world'.
How to apply lowercase filtering on a text column in Oracle?
To apply lowercase filtering on a text column in Oracle, you can use the LOWER function in a SELECT statement.
For example, if you have a table called "employees" with a column "last_name" that you want to filter in lowercase, you can use the following query:
1 2 3 |
SELECT last_name FROM employees WHERE LOWER(last_name) = 'smith'; |
This query will retrieve the last names from the "employees" table that are equal to "smith" in lowercase.
How to convert a string to lowercase in an Oracle query?
To convert a string to lowercase in an Oracle query, you can use the LOWER()
function. Here is an example query that demonstrates how to convert a column value to lowercase:
1 2 |
SELECT LOWER(column_name) AS lowercase_value FROM table_name; |
In this query, column_name
is the name of the column that contains the string you want to convert to lowercase, and table_name
is the name of the table where the column is located. The LOWER()
function is used to convert the value of the column to lowercase, and the result is displayed in a new column named lowercase_value
.
You can also use the LOWER()
function with literal strings. For example:
1 2 |
SELECT LOWER('HELLO WORLD') AS lowercase_string FROM dual; |
This query will return hello world
as the value of the lowercase_string
column.
