To concatenate two strings from two queries in Oracle, you can use the concatenation operator (||). Here is an example: SELECT query1.column1 || query2.column2 AS concatenated_string FROM query1, query2 WHERE query1.id = query2.id; This will concatenate the values of column1 from query1 and column2 from query2 into a single string and display it as concatenated_string in the result set.

How to concatenate strings from different columns in Oracle?

In Oracle, you can concatenate strings from different columns using the || operator. Here's an example:

SELECT first_name || ' ' || last_name AS full_name FROM employees;

This query will concatenate the first_name and last_name columns with a space between them and return the result as a new column named full_name.

How to concatenate strings with a space in Oracle?

In Oracle, you can concatenate strings with a space using the || operator. Here is an example:

SELECT 'Hello' || ' ' || 'World' AS concatenated_string FROM dual;

This will output:

concatenated_string

Hello World

In this example, we are concatenating the strings 'Hello', a space, and 'World' using the || operator and specifying a space within single quotes.

How to join strings from different queries in Oracle?

To join strings from different queries in Oracle, you can use the concatenation operator (||) in your SELECT statement. Here is an example of how you can achieve this:

SELECT query1.column1 || query2.column2 AS concatenated_strings FROM query1, query2 WHERE query1.id = query2.id;

In this example, we are selecting column1 from query1 and column2 from query2 and concatenating them together with the || operator. Make sure to replace query1, query2, column1, column2, and id with the appropriate table and column names from your queries.
