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 unid, FirstName FROM Person WHERE City = ?",
    data = data.frame("Miami")
)

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