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 From_User_Name, Text FROM Tweets WHERE From_User_Name = ?",
    data = data.frame("twitter")
)

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