[SOLVED] Is there a way to implement cassandra "decimal" Datatype in Golang

Is there a way to implement cassandra "decimal" Datatype in Golang

I have a database field that is set to decimal, while in my Go project I am having problem choosing which datatype can be used. each time I send a create reuquest to my code, I get a "cannot marshal 'decimal' into #golang datatype#

this is my database schema

CREATE TABLE transaction(
organization_id timeuuid,
month text,
employee_id timeuuid,
id timeuuid,
employee_name text,
amount decimal,
deductions int,
date_approved date,
PRIMARY KEY ((organization_id, month), id)

)

my golang models looks like this

type WageGarnishment struct {
ID            gocql.UUID `json:"id"`
organizationID            gocql.UUID `json:"organization_id"`
Month          string     `json:"month"`
Amount        Float64    `json:"amount"`
Deductions    uint       `json:"deductions"`
EffectiveDate time.Time  `json:"effective_date"`
DateApproved  time.Time  `json:"date_approved"`
EmployeeSummary

}

no matter the datatype in my Amount Field I keep getting this Error:

Error #01: can not marshal float64 into decimal

Thanks for your Help in Advance

Solution

If you look into documentation for Gocql package, then you will see that the decimal is mapped to the Go's infDec data type (see its doc) so you need to use it instead of Float64.
