如何在 sql 中进行类似条件的内部连接

Question

Basically i have two tables and the two tables are EmployeeDetails and SalaryStatement are described below.

EmployeeDetails table:-

SalaryStatement table:-

I need to use the Employee_name field from EmployeeDetails table and see whether it is used in Operations field from SalaryStatement table. If the string "Name1" matches i need to do inner join from table1 and table2 considering all attributes from two tables. I am not sure how to use LIKE condition in inner join. Table 1 EmployeeDetails table is the base table here.

Answer 1

If you want the employee's name contained inside Operations then do this:

select *
from EmployeeDetails e inner join SalaryStatement s
on s.Operations like concat('%', e.EmployeeName, '%')

or maybe:

select *
from EmployeeDetails e inner join SalaryStatement s
on s.Operations like concat('%(', e.EmployeeName, ' ==%)%')
