I have been trying to use the postgres IN clause in golang, but keep getting errors. This is the query I want to execute.
SELECT id1 FROM my_table WHERE type = (an int) AND id2 = (an int) AND id1 IN (list of UUIDs)
I used this code to construct this query but got the following error.
var params []interface{}
inCondition := ""
params = append(params, type)
params = append(params, id2)
for _, id := range id1 {
params = append(params, id)
if inCondition != "" {
inCondition += ", "
}
inCondition += "?"
}
query := fmt.Sprintf(`SELECT id1 FROM my_table WHERE type = ? AND id2 = ? AND id1 IN (%s)`, inCondition)
rows, err := db.Query(query, params...)
Query I got:
SELECT id1 FROM my_table WHERE type = ? AND id2 = ? AND id1 IN (?, ?, ?)
Params output:
[]interface {}=[0 7545449 d323f8d5-ab97-46a3-a34e-95ceac2f3a6a d323f8d5-ab97-46a3-a34e-95ceac2f3a6b d323f8d5-ab97-46a3-a34e-95ceac2f3a6d]
Error:
pq: syntax error at or near \"AND\""
What am I missing? or, how will I get this to work? id1 is a slice of UUIDs whose length is variable.
