I’m trying to insert single values from other tables but getting this error. If you know that how to fix then please fix mine code …
Check this:
INSERT INTO Library_Records_DB(Book_Name, Student_Roll_Num, Student_Name, Student_Department, Lending_Date) values ( "English", 747, (select Full_Name from GCUF_Students_DB_Morning where Roll_Num=747), (select Department from GCUF_Students_DB_Morning where Roll_Num=747), "01-jan-2020" )

Answer
I’d try something like:
INSERT INTO Library_Records_DB (Book_Name, Student_Roll_Num, Student_Name, Student_Department, Lending_Date) select "English", Roll_Num, Full_Name, Department, "01-jan-2020" from GCUF_Students_DB_Morning where Roll_Num=747
(But I don’t know your data. Will the select return one row?)
