QuestionsProblem with multiselect filter
c3media asked 6 years ago

Hello Abu,


Have two tables:

Products and Categories

Both has id field, so Products table have a field names Category_id.

Then get problem because in example you have field as client_id for table client, then it has issue to work showing message:

Couldn’t execute query. Column ‘id’ in field list is ambiguous – SELECT count(*) as c FROM (SELECT id, name FROM products INNER JOIN categories on products.category_id = WHERE 1=1)


Thanks by your help

To avoid ambiguity, you need to set table.field in dbname property: e.g.
$col[“dbname”] = “”;
