The following code example shows how to bind parameters to create parameterized statements.

Single-Use Statements

The Query and Exec functions both accept additional parameters for binding query parameters to values.

rows, _ := db.Query("SELECT Type, DatasetName FROM Schemas WHERE ProjectId = ?", "bigquery-public-data")
defer rows.Close()
for rows.Next() {
        var (
                Type string
                DatasetName string
        )

        rows.Scan(&Type, &DatasetName)
        fmt.Printf("Type = %s, DatasetName = %s\n", Type, DatasetName)
}

Reusable Statements

The Prepare function creates prepared Stmt objects, which can be re-used across multiple Query and Exec calls.

stmt, _ := db.Prepare("SELECT Type, DatasetName FROM Schemas WHERE ProjectId = ?")
defer stmt.Close()

rows, _ := stmt.Query("bigquery-public-data 1")
defer rows.Close()
for rows.Next() {
        var (
                Type string
                DatasetName string
        )

        rows1.Scan(&Type, &DatasetName)
        fmt.Printf("Type = %s, DatasetName = %s\n", Type, DatasetName)
}

rows, _ = stmt.Query("bigquery-public-data 2")
defer rows.Close()
for rows.Next() {
        var (
                Type string
                DatasetName string
        )

        rows2.Scan(&Type, &DatasetName)
        fmt.Printf("Type = %s, DatasetName = %s\n", Type, DatasetName)
}
