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

Single-Use Statements

The sqlExecute function from RODBCext accepts an additional data frame for binding query parameters to values.

sqlExecute(
    cnx,
    query = "SELECT Student_ID, Transaction_Number FROM [CData].[Btrieve].Billing WHERE Student_ID = ?",
    data = data.frame("22")
)

results <- sqlGetResults(cnx, max = 1000)
while (is.data.frame(results)) {
    for (row in 1:nrow(results)) {
        cat(paste("Student_ID = ", results[row,]$Student_ID, "\n"))
        cat(paste("Transaction_Number = ", results[row,]$Transaction_Number, "\n"))
    }
    results <- sqlGetResults(cnx, max = 1000)
}
