Parameterized Statements

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 High, Date FROM AAPL WHERE collapse = ?",
    data = data.frame("daily")
)

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