It derives initialization property named_param_prefix
IBProvider:

This property determines prefix of the named parameters in the query text.
Allowed values: «», «:», «@».
If you set empty string into the property then provider will not support named parameters. This functionality is necessary with the executing of DDL queries (in IBP v1, v2).
Starting with provider version 5.20, modification of the value of this property will put the command in an unprepared state.
