golang sql pointer values keep repeating itself - sql

Question

Below is a golang function which is being called with an input channel
func getOptions(inChannel <-chan Param) <-chan ParamOptions {
paramOptions := make(chan ParamOptions )
go func() {
defer close(paramOptions )
var wg sync.WaitGroup
conn, err := sql.Open("mssql", wellConnStr)
if err != nil {
log.Fatal("open connection failed:", err.Error())
}
defer conn.Close()
getParamOptions := func(db *sql.DB, param *Param) {
defer wg.Done()
fmt.Println("querying options for ", param.Code, param.Name)
rows, err := db.Query(`select *
from dbo.ParamOptions where code=? and name=?`, &param.Code, &param.Name)
fmt.Println("results for ", param.Name, param.Code)
if err != nil {
log.Fatal("query failed:", err.Error())
}
defer rows.Close()
found := false
...
paramOptions <- ParamOptions...
break
}
if found == false {
fmt.Println("did not find options for ", param.Code, param.Name)
}
}
for paramInChannel := range paramChannel {
wg.Add(1)
fmt.Println("retrieving inputs for ", paramInChannel.Code, paramInChannel.Name)
**go** getParamOptions(conn, &wellInChannel)
}
wg.Wait()
}()
return paramOptions
}
If i remove the go keyword before calling the function getParamOptions it works without any problems. However if I use go then the last code and name keeps repeating within the the getParamOptions function, even though the options retrieved seems to be of the correct Param, the Code and Name values are being repeated
