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 ID, Leave_Type FROM [CData].[Employee Management].Leave_Types WHERE Leave_Type = ?",
    data = data.frame("Sick")
)

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