I want to display all the names in a table that contains the character ‘+’ but it doesn’t work on Oracle SQL developer, while the column contains names with ‘+’
Select *
from Table where NAME like '%+%';
==> I got an empty output
Example:
Could you help me please ?!
>Solution :
In Oracle, the + character has a special meaning in the LIKE operator, as it represents a single character that can be any character. This means that the %+% pattern in your WHERE clause will match any string that contains a single character between any other characters, but it will not match a + character itself.
To match a + character in a LIKE clause, you will need to escape it using the ESCAPE clause. The ESCAPE clause specifies a character that will be treated as an escape character, allowing you to match the actual + character instead of its special meaning.
Here’s an example of how you can use the ESCAPE clause to match the + character in a LIKE clause:
SELECT * FROM Table WHERE NAME LIKE '%+%' ESCAPE '+';
This will match any string that contains a + character, regardless of its position in the string.
