Search a string and display all items containing that string

[Richard Alvarez]

i put a search on my program and i use SQL. I want my search function to search even just the part of the string in my access database. how would i do that?

the problem is that it searches for the whole match of the string. i want it to be like this
the field contains john Castro, Robert So, Rick Williams ....
and if i type "john" it will display all records with the word "john".

please help me with.
much appreciated.

Instead of the = operator, use the like operator with wildcards.

[Richard Alvarez]

That "LIKE" thing, is that something like this;

Set rsData = DBConn.Execute("SELECT * FROM tblMasterData WHERE EmpName LIKE '" & Me.txtSearch.Text & "'")

Sir i'm sorry to admit that i'm new with these SQL lines.
Culd you give me some example please?

[Rabbit]

The exact syntax and wildcards depend on the DBMS that you're using.

SELECT *
FROM SomeTable
WHERE SomeField LIKE '%hello%'

[Richard Alvarez]

In my program, the user will input his/her query in a txtbox, so how would I going to replace that '%hello%' with my txtbox like '"%me.txtFName.txt%"'?

[Richard Alvarez]

Sir here is what I did but still don't know if it's correct.

Set rsData = DBConn.Execute("SELECT * FROM tblMasterData WHERE EmpName LIKE" & "*" & Val(Me.txtSearch.Text) & "*")

[Rabbit]

You do it the same way you have it in your original code. Except now you're using Like and wildcards as part of the string.
