Question

I have 2 tables
Table1:
======
ID Name EmpID
== ==== =====
1 Dan 12
2 Isaro 13

Table2:
======
ID Name EmpID
== ==== ======
1 Muhi Dan NULL
2 Johanna Isaro NULL

I want to insert into table2 the EmpID from table1 but I want to check if Dan, Isaro from the table 1 exist in the table2. If so then it can insert into table2 the same EmpID from table1.
As u can see in the table2 there is muhi Dan means Dan exists in the table2, means then it should insert this.
How to perform this?

Solution 1

SQL

UPDATE Table2
SET EmpID = t1.EmpID
FROM
    Table2 t2
INNER JOIN
    Tabel1 t1
ON 
    t2.Name LIKE '%' + t1.Name

This makes sure that the name in table2 ends with the name in table1.

Solution will give a wrong result if substring of other name is same as the name you are looking for eg: if 'Jordan' name exist in table instead of dan it will still give you the output

You are right. Insert a whitespace before the Name: LIKE '% ' + t1.Name to only get full last names.
