I have a table
doctors (
id int,
name varchar(255)
)
where name like “Sername Name”.
In query i need only Sername of doctor. How can i do it with standard or with solution on most RDBMS?
I know only two solution.
First is SUBSTRING(input SIMILAR pattern ESCAPE escape-char) in postgres is SUBSTRING(input FROM pattern-string).
Second is in postgres like substring(name, 0 , position(' ').
UPD: Is it normal to ask rdbms to split string or better do it manualy in code?
