Topic: Sampling of records on intersection of field values and line
There is a table ` agents ` in which there is a string field, for example ` business `.
The whole natural numbers divided by a comma are stored in this field - "10,15,25,7,1".
Numbers in this field do not repeat.
Sortings of numbers in this field are not present, but, if needed, it is possible to make.
String constant Str which on value is similar with the above described field is set - i.e., in it the whole natural numbers divided by a comma are written down. Numbers do not repeat also sortings are not present (but it is possible to make).
It is necessary to select all records from ` agents ` in which the field ` business ` contains at least one number entering in Str.
Whether there is a possibility to make sampling by one request?
