Query Custom Object3 using Like

Question

Hi,
A customer has many models attached to him .Each model info is maintained in custom object 3 . We have maintained External Unique Id of model(object3) in the format custno-modelno .So each model is identified uniquely by external unique id. I want to delete all the models of that customer using webservice delete mechanism . Inorder to accomplish that we are query the object based on external unique Id to get all models assigned to the customer and delete . In the query expression tried to use LIKE operator ( ex : find all models for customer 1234; query-expression is 'LIKE 1234-' ). But query does not result all the models .
Can anyone help me on this .We are using ondemand 19

Hi,
Thanks . All the models for a particular customer have customer number - in common. So If the query can give all the models of that customer i can omit all the models using delete operation .
Example :
customer # 1234
model1: t20 externalunique id: 1234 - t20
model2: t40 externalunique id: 1234 - t40
similarly all models of the customer have 1234 - in their external unique Id .So I was trying to perform query using ' LIKE 1234-' here '-' is a wildcard .
But the WS did not give back any result .
Only if we query '1234-t20' then the response document is not null.
I would like to know the query expression in such a scenario.
The WS user trying to perform delete operation has the required permission
